I just bought 2 Falcon's and one has a FX-1 label on it... Have not opened it, but is that likely going to be a Sparrow MB?
Did you ever open up the boxes?
Been waiting on that.

Hmm, I never tried this monitor with a Falcon. I'm using it with my Mega STe
and an Exxos version of the UBE VGA adapter. I've been pleased with the results
so far, especially the size.
It's very doubtful that anything else ever will be...
Oh, they are definitely to be bought in 6 packs
I'd sold all my ST/e/TT before and just after moving to Oregon. Only Falcons left. These are the cats meow for the ST resolutions.
Not sure if you remember, I'd posted a hack to get the generic Chinese RGB 2 HDMI to work on the Jag.
On top of that,the Falcon also had a quirk where when connected, the box shorted the Falcon video. Forget the pin now, I'd have to look back. But think the ST and Falcon probably have the same pin outs in respect to RGB mode, and whatever that was (pretty sure it was DC) if bleeding across the cable, could be causing it.
Or I could be full of it 😆

Just caught up on the thread.
Vertical lines with Atari video, yes. Think what I'm seeing (eyes are older than Darklord's) is they "seem" worse at lower resolutions, but think it's the changing of dot pitch, kind of like blowing up an image to the point where quality degrades is what it resembles.
Text was fuzzier in mono, I thought, at least TOS fonts. I wouldn't want to write a book though in any ST interlaced mode
Maybe playing with NVDI and installed system fonts could make it more gooder.
What I found odd was most everyone is saying the vertical "lines" are most noticable on dark/black background. To me they really stood out on the "normal" Atari green, and were virtually unseen when loading Ease desktop, with black background and desk pic. Didn't see that anyone else tested a different desktop. Ease is heavy, but the icons, boxes and such are too notch.
Might also be something true about buffering the video output, or playing with resistor values. Forget what I'd done, but the display revealed some ghosting on a white background, making me think it's not an RGB color space thing, seems a signal issue. Had to look close, but it caught my eye.
And I'd have to go back and look, but don't recall seeing the vertical jail bars during boot, before GEM loads.
The member that had the monitor hooked up to test equipment maybe could chime back in with any new test data.
I don't have any games on the HDD (rocks flying), did run several demos, they all displayed nicely in RGB mode.
Honestly, demos, and a few games are mainly why I jumped on this for RGB use.
The vertical lines are present in VGA mode too, again Ease cleaned things up.
This was checked under standard Falcon modes, unless a demo used a custom setting (the aforementioned test equipment could verified).
It's also Afterburner equipped, runs the bus as 23MHz, 040 CPU and fast RAM at 46MHz. TOS ROM is edited to keep the Blitter at 1/2 CPU clock (11.5MHz).
With the Afterburner, have a NOVA adapter and ATI MACH 64 with 4mb VRAM ISA card.
First thing I'd noticed was most the resolution configurations for the previous monitor didn't work. Think it was an early 17" NEC Multisync LCD (like a bunch of others, took 6 or 7 monitors back to the thrift store after buying these
)
Looking the data sheet for the SE2722H it has a pretty wide band with, but using the video mode generator to enter preset display modes really didn't work for other than 640*480/800*600 24bit. So I'm not sure if it's just fussy, or the video mode generator is showing it's age (mid 90's soft). Unfortunately, NVDI can only configure ET4000 cards. So not sure what the magic is there. Just have to spend the time hitting each resolution's sweet spot.
On the ATI, std VGA at 24bit is rock solid. Looks better than the (bought 2) display output on the ASUS quad-core income tax machine
I'm really impressed with it, know it didn't sound like it, but at $118, I'm going to buy 2 more, one for the toy hauler, and one for the wife's laptop when "docked".
Still think there's a lot left on the table experimenting with the video signal signal.
But it will never be a 1224

Thank you for all the time
That is a huge effort.
Just now starting to do a hand delineation of the Falcon COMBEL to PGA socket adapter, to connections, and Sparrow COMBEL PGA socket to connections. I'm staring at hours and hours of work

Finally had a few minutes at 3am last night to try the SE2722 on an older (pre-consumer) Falcon. (More at the bottom on this).
I'd purchased 2 as the old Dell on the PC started acting up. First impression on the PC was it's average. The older Dell was "only" 24", 27" is nicer (and much lighter). FF a month to last night. Didn't even start off in VGA modes, went right to RGB to test.
Just wow. Honestly, it was difficult to distinguish between modes (VGA vs RGB). Owned a lot of "compatible" LCD-LED used monitors in the past, the SE2722 blows them away.
With only 4mb RAM and a bad DSP SRAM on this board, was limited testing.
Used the APEX viewers for Targa files as well as ImageCopy for viewing.
In 640*400 TC, forgot was even in RGB mode, and started playing with the dither setting in ImageCopy.
Even in interlace mode, ImageCopy presents a stable image, only noticable outside the image borders.
Tested all stock Falcon video modes (sans ST High), no stability or odd syncing noticed.
Think I've read in some of the above post about vertical lines on the display.
These were evident in both VGA and RGB. It's annoying, but not a deal breaker.
Back when Nemesis was first released, Titan (Dave, Doug and crew) were supplying all sorts of tricks and tips.
One of these was to clip out the resistors on the video output and replace them with induction wire pieces.
This Falcon came without the video load resistors.
Been years, my Afterburner Falcon had the resistors removed at some point, and notice now (long forgotten) I'd resoldered them back in place.
I'll move that motherboard back to the bench and retest the monitor there.
Again, have to reread the thread if someone posted a solution for the vertical lines.
Can't wait to try the Sparrow on this as well. While it's "supposed" to have compatible ST video modes, came across one setting where the NEC Multisync couldn't display the mode, and another (forgotten) monitor could. So there's an odd ball frequency there one may think (if having a Sparrow) there is no video output. It does, but if coming across the configuration, give another monitor a try as all the Sparrow video modes do work.
Images displayed in 640*400 TC mode using ImageCopy.

Down to $169.99 at Microcenter -
https://www.microcenter.com/product/638580/
Office Depot / MAX $159.99 until the end of July
https://www.officedepot.com/a/products/9072317/Dell-SE2722H-27-FHD-LED-Monitor/
I'd tried Microcenter on my phone, it spit and sparked for some reason. Googled the monitor and came up with the Office Depot site.
-
Oh, from Office Depot out of San Jose.

Back from the dead
Finally jumped on 2 of the SE2722's. $319 delivery next day.
The early 2000 Dell 24" I'd been using on the PC went on the blink, and the really old (forgot what brand, it's burried during a computer room remodel) monitor that worked in RGB mode on the Falcon wasn't best video quality.
Being 66, 800x600 on a 24" was really getting difficult.
These should shine with the SuperVidel as well as the occasional RGB demo's on the Falcon.
Thank you all for the testing

How are you with SMT MACH CPLD? (ex, Afterburner040).
-
Umm, Sparrow....:)
-
Sometimes the file will need to be byte swapped before burning.
When you load it into programming environment, TOS 4.04 first word should be 602e.
If it reads 2e60 or else, you need to do a swap.
I have CGYWIN on a PC, and use dd.
I can send a 55ns Amtel with 4.04 when I send the COMBEL.

Atari themselves manufactured the limited quantity of poorly marketed Falcon Computers.
However a company called C-Lab got license to produce their own near identical Falcon "MK2" computers until 1996 or 1995.
Pretty sure all C-Lab did was to reutilize stock. They fiddled with hand picked DAC's, noticed those replaced on 4 different C-Labs I've owned/own.
Interesting with the MKX, if indeed they stripped Falcons out of the Atari branded cases, or just sourced a quantity of motherboards. If the first, they should of been an excess of standard Atari cases you'd think.
Here's a odd one for you?

Sorry, I don't know what the CT60 package is, can't find any link to it, also don't know any Mikro, googled, but got nothing relevant
Apologies, even though a small community, big internal foot print
The CT60 (68060 accelerator card for the Falcon) comes with a small set of soft tools. One is a patch tool to update xcontrol.acc for 68060 compatibility. Over time, Atari had updated the file. Roger Burroughs (ExtenDOS) mentions an issue in EmuTOS where his solution is to use a later version of it.
That's just an example for using a later version.
Short answer I guess, find an online archive containing the disk that came with each machine. XCONTROL contained on the Falcon disk is the last version from Atari.
Don't know the specifics of what is patched using the patch program included with the CT60, may not be necessary in your instance. Just pointing out there are a few versions of it, it's known to cause issues in some cases.
I know, I talk too much
-
For xcontrol.acc, use the version included with the CT60 package. Its been patched. Mikro's GitHub page has the file and description.
Don't think it relates to NetUSB.

Been many years since using the HDDriver demo. Think one of the limits use to be only SCSI ID 0 was supported to boot from.
That drive may pre date me
Generally SCSI devices don't (and shouldn't) need to be formatted, only partitioned. On an Atari, even a 10mb drive would take ages using AHDI.

Anyone have an Swiftcalc Version 2? I think all the common online sites have version 1.
Have the SwiftCalc package, no indication of the version. Currently can't install to verify.

Hehe, these are cropped phone shots of the menus on an old LCD.
The quality is pretty good on a proper display.
Messed with most any and all converters, for the price it's pretty good.
If you want to spend more, guess the OSSC is a good option.
Have a Sony BVM-D24E1WU outfitted with a few input cards. Has maybe 120 hours on it, just haven't gotten around to setting it up. It too is a monster. RGB there, without a converter is as good as it gets.
-
Have 2 of these units. They must have a small modification done internally, but work quite well (subjective) with the Falcon and Jaguar, including audio.
Recently purchased an OSSC, yet to setup.
Here's a link to the post here.

Let's do the time warp again...
I'm 59 now.... LOL
Yes, added that up for you
Since the start of this post, as everyone else that has been around for years, have taken in a lot of knowledge for all different types of Atari hardware. During the "Great ST Purge" of 2015, and since, have downsized significantly.
3 Falcons and the Milan remain. The worse part is, since 2008, have learned to write at most 2 or 3 lines of code
So many here are fluent in language. I can type up a storm, that's about it.
Happy with the 2 CT60 setups. Aquirred 2 years ago an Amiga 040-060 adapter, same design as Michaels. Without diving into the IC replacement beneath the CPU of the Milan, haven't been keen on going back to troubleshooting it. I'd found a good thread of all that's involved to have the Milan running well at 20mhz buss on the German Atari forum.
Currently reworking hacks done to my original 1994 Falcon over the years. Had a scare, after socketing the NVRAM, failed to boot the diagnostic cart. Turned out I'd only tacked the socket in place
After resolving that, she lights up just fine. All the pins from the past that were cut for the Nemesis install have been socketed, like the ACIA'S. This allows an independent and much cleaner solution to providing the 500khz via oscillator to each, as well as a smaller smt 48 DSP clock on the underside.
Currently working 2 68040 PLL clock drivers into the system, one setting at the SDMA clock input, and other for expansion and COMBEL distribution across the board.
In the past have toyed with overclocking the FPU. It becomes unstable around 40mhz. Being not of sound mind, and not sure what caused the direction, discovered the FPU (and 20/22mhz bus) settles down using a 64mhz FPU clock. Think Exxos mentions this, at a much later date than I'd discovered. Not sure if we were of the same mind, or he actually read through one of my book post
I did it again! Too much brainstorming.
Last notes I have from Doug Little, he pointed out the clock driver on the AB is only rated at 70mhz (35mhz BCLK) and felt that could be leading to stability issues running the AB over 44mhz. Have a supply of 100mhz IC's, will be using those to test soon.
Where I'm kind of at is all this will still require fly wires across the board. An eBay seller that had some interesting 90 degree ISA card mounts said he'd be willing to make a custom board of my layout to resolve this, as did Frank Lucas. Just need to sit down and lay it all out once the AB is back up.
I'm visualizing an expansion pin supported narrow PCB, with onboard oscillators, Vcc, and pick off points next to critical clock line placement for the VIDEL, SDMA. Wondering, without a scope yet, if an inverted PLL clock from the drivers can replace the traditional Falcon clock patch.
Currently in a holding pattern. I'd offered to setup my spare CT60e and SV for another member on Atari forum and aid troubleshooting. He's not yet replied. User has been having no luck with Insanes CT TOS and his e for a year now. That offer will expire shortly
And where is Jen's? Haven't seen him post in some time, and always become concerned when an Atari user that is legacy to the platform just drops off.

We hear ya brother. I've got so much STacy stuff now, I think I could build a couple
of extra machines from the spare parts. But you know what, that's perfectly okay.
I'm a respiratory therapist at a small rural hospital (St Joseph Martin). This is my
31st year there. They have a retirement plan, but its one of those that works just
like regular retirement, so the earliest I can leave is at age 62. I'm 51 now, so I've
still got a long ways to go. I now what it means to put that much time in, so I'm
glad to see someone getting out, and I sincerely hope that the time from that
moment on is the best years of of your life!

Some years ago sold most everything other than a couple Falcons and associated hardware. I was a subscription freak, but those too all were sold of. Thanks so much for saving all this
Aside from a bunch of cover disk i never go around to parting with, have one issue of Atari Computing August 1997 from a subscription I'd ordered for my mom. After she passed in 2013, I'd found it packed away, unopened
Now living in Oregon, wonder if any of those early folks are still around. Steve's Computers and the magazines produced in the area.

$20+$15 USPS Priority Mail Flat Rate Medium box. 10 lbs. US shipping only.
Update: I'll throw in another EZ135 to go with your other Atari, Mac or PC with SCSI to transfer between machines for another $10 + shipping, allow another $10 shipping, the other box is packed full. Just let me know if you want it when replying. PayPal works best.
Realize this is fairly dated hardware, then who here doesn't own something dated.
During the quad annual Atari room clean out, selected 16 EZ 135 removable disk as items to go to the thrift store, leaving me with 8 disk and 3 EZ drives.
Thought about the "hardcore" stock 520 and 1040 ST users, decided first to make up a small "package" for offer.
If you are working with half MEG of RAM, TOS less than 1.04, this will make life easier in some ways. Using ICD Pro (and a SCSI host adapter of some flavor) you can use each disk as a 135 MB bootable drive, with 16 different installation on each. Takes all but a reboot (if used as a bootable drive) and 40 seconds later working in a different customized environment
Would be my use anyway if that was an only setup. So many ways now to use "modern' storage, this is the way it "use' to be done.
Included CD Recorder Pro, which uses floppy in drive protection. Think this is not the latest version, but it's manual is at least in English, purchased from System Solutions via Toad Computers.
Not familiar with Sound Lab, reading the docs noticed something about compatible with a few different ST sampler carts, Replay 16 was one. It's serialized software, don't know if it's copy protected.
SCSI Tool and HUSHI are both in German, ordered from ASH via their old BBS system. They may or may not be revelint today.
To use the EZ135 drive, an ASCI to SCSI adapter is required (or TT/Falcon), cables. The disk are currently partition as 135mb BGM. Maybe 2 have not been setup. Thought I'd check in, save someone a trip to the thrift store
SpoilerDon't think I missed anything

Thanks a gazillion!

(pending pickup)
To good home.
Both in good working and cosmetic condition.
Think both Goldstar, with integrated 13pin cable.
Shipping in the US cross country guessing about $40-$45.00 each, but would need a postal code for exact amount.
Located 97439, Oregon.
Pick up ok, make it short and sweet, no meet up's, won't hold.
Need the space. Going to Goodwill soon.
PM with interest
PayPal only please.
Been waiting on that.

I'm not that familiar with cartridge based units, am fully aware of their existence and importance to the Atari name.
Have there been any back burner thoughts on Motorola based computer products, in the spirit of what once was?
Those too support many legacy games, with an actual programmer base I'd think would be chomping at the bit for opportunity to provide commerical quality products on capable computer or cartridge based computers.
Just a thought.
