I bought this like foreverago
its in good order.
i think 30$
It is rare museum piece..
I will ship it
You look up its application, it seems to be fine with eight bit

Well, I made much better progress than I thought I would this evening. All soldering is done, save for the Level 2 board. No pics of the back yet as the board is still caked in flux.
It's neat - take and my previous image, it's a great before & after, almost perfectly lined up. Wish I could properly edit photos to make them match.
BTW - I'll have more images posted in higher resolution at my Flickr site - 1088XLD album is https://www.flickr.com/photos/75619516@N06/albums/72157705660251381
So the cartridge slot will have to be milled out of the top case? The 90 degree angled slot of the 1200XL could work here with an extension to the backplate?? just haven't seen the cart come to fruition yet.

Very nice!
Wonder if Serdashop noticed any uptick in S2 DeamBlaster sales recently 
I just bought one!

Yes - I hope it doesn't re-yellow on me. Oddly, none of the gear I owned ever turned colour. Non smoker, and always covered, out of sunlight, and temp stored. I am a "night owl". Light sensitive, prefer the dark, etc. This was an ebay item, broken, that I was trying to fix.
Oh - no tricks. 40 vol cream lightener, saran wrap, and sunlight. Re-applied every 30 minutes for 3 hours, and I had this perfect result. Ambient temp was 73, moderate humidity when I did this (outdoors).
where do you find 40 volume cream lightener?

I am also a 1200XL fan and i owned 4 at one time.. I would buy one in excellent condition for 200$ plus shipping to Pittsburgh PA. interested in dead units that have decent cases for 80$

That is so damn pretty. Here's a before and after on the case I am using for this drive:
do tell! did you micro airbrush this beast?

You make me want me to say Happy Thanksgiving due to your tenacity and drive and I thank you immensely, although I am sure most of us have been treated with the best Christmas present ever at one time.
Happy Hanukkah and or Merry Christmas.
Peace Love and Happiness!

Was it an Atari?
I landed in Kingman Arizona with a dead radiator. The Business i arrived at was a radiator shop. OLD SCHOOL!
I saw him look up my part and it was definitely an 8 bit program. It probably wasn't an Atari but the whole process took me back to the 8-bit.
His inventory was entirely driven by an 8-bit computer and the invoice was a digital representation of an 8-bit era printer.
He still runs his tight inventory and clean billing on an eight bit. he didn't look for the part online! he saw that he had it in stock!
I was blown away! and when your driving cross country.. he didn't rape me for cost. LABOR cost a bit but i made it on my way with no more overheating.
eight bit worked for me.

I am not going to start a new thread.
I just wanted to show you my build.
It cost a bit more, more..
But i have no intention or need to do this again with gold contacts.
I will do the same when the 1088XLD comes of age.
I was the last of the few that did this.. I wish I was involved when it happened.
I cannot wait until i get my flashed PIC's

Hay kinda the same thing here. I would love to help in the process. I don't care if it sounds like a machine gun but has anyone thought of silicon?
Kinda a pink orange rubber that is very easily molded yet I am unaware if it work well at these small dimensions.
Side note... I am VERY interested in a clean case to mod a 1200XL keyboard enclosure for a 1088XEL build.
Thanks! I will repost in WTB.
But feel free to PM me

cbelcher, I hate seeing naked 1088XEL boards. Not that there is ANYTHING wrong with not having it in a case, but . . . I did a test print of a case. It's not perfect, and I need to run a lid for it, but since I am going to run another print to test out some changes, I would *gladly* send you this case for the cost of shipping. Just so you could protect that nice piece of machinery (and I could sleep more easily at night
. Again, nothing against it or anything, but I saw this post and I have this thing . . . . Let me know. (The backplane is just to show the fit, it is one of the things I need to tweak. It works, but not to my satisfaction).Wow you have a printed case! so you do that sort of thing on your offtime..hehehe
is this tru?
also can i use two dual cf adapters? I really like the pretty blue top lid but i already have the dual backplane, so.....are these units compatible like the multi IDE cables suggest?

sorry the piano was drinking. i tried to plug in the idc into the JTAG

He evidently used a micro header in stead of a standard IDC header..

So anyway
I got the new U1MB from lotherak
and the large headers work like a charm
but the little header dont fit at all..

BTW,
What is the key capacity? can i use a 104 key? Atari only had a 54 key board!????
Douglas

Schematics for every Atari related gizmo I've made are on my website. Use the link in my signature to take you there, then click on the TK-II tab. Or better yet use the TransKeys link
.Found it and i am in grossed in fingering it out thanks. I thought the schm files were for your mini boards but it seems that the most of your mini boards are connector space..
Thanks

Hello 576XE
We've had something like that:
They probably didn't sell enough to redesign them for the XL and XE series.
Sincerely
Mathy
PS it's the CX85
But the switch matrix is mechanical and the drivers are needed to use this thru the joystick port. but you could in theory wire the switches into a 1200XL or likewise keyboard during breakout.. ie wire the CX85 swithces to your mylar..
Douglas

I would check the connector at the motherboard as well as the resistors associated with the data lines from the keyboard.
Get the matrix as in last post and test continuity between the switch matrix
-
A pinout of the TK-II would really help..
Thank You!

Hi Bill,
Yep that's what I thought as well
However in order to be able to have Start, Select, Option, Reset from the keyboard, it will require some jumpers be soldered internally to the D-SUB 15 connector. Minimally at least the reset capability should be added in this way, which is a very simple short distance jump. But it is not an absolute requirement, more for ease of use, since this key does tend to enter the picture often when developing code.
It really is too bad that these signals weren't routed out to the keyboard in the first place, since there were enough unused pins to allow for it, and the console switches do exist on the XEGS's keyboard (just no buttons). This also assumes that only one pin would have been dedicated to GND and another for +5VDC, unlike the doubling up that was done (kind of stupid considering that only two low power CMOS chips are used in the XEGS keyboard). This of course makes it more difficult to use these pins for other things, since the D-SUB 15 connector would need to be fully removed (desoldered) in order to cut the power trace connection on the top side of the motherboard. But like I said it is not a requirement that the extra signals be implemented for TransKey-II in order to work.
XEGS Keyboard Connector Pinout
Edit: Just to be clear, the TransKey-II-XEGS model will already have the connections for Start, Select, Option, Reset routed to its D-SUB 15 connector, two of which will be via on board limiting resistors, in case the XEGS has not been modified and the +5VDC and GND connections are still intact. Don't want to blow out the TransKey-II's I/O, if plugged into a friends unmodified XEGS.
So one is the mylar breakout of the XEGS and the other is the board for the XEGS matrix keyboard.
The matrix board is otherwise known as the "Keyboard Sub Pcb" atari pn C100425 Rev 2
It appears to have a series of 470ohm pull up resisters to deal with the cable length, but i could be wrong but the 1200XL dont have them.
I am very interested in adding a 1200xl keyboard to my 1088xel project using a cable.
Thanks

Just a question about old midi vs new midi...
I see that BEST is selling an old ATARI MIDI peripheral. Are there any differences in the new MIDI keyboards vs the ones from the mid eighties?
In other words if the new keyboard has power, MIDI in and MIDI out, I would think it would work with the older ATARI MIDI peripheral.

can anyone tell me the orientation of Q3 and Q4 transistors under the Pokey chip?
Douglas

Ok, everything is socketed, plugged in, going green. Oh, wait! No video cable for Sophia!!! But the board looks great. I'll work on cable this week;--)
Good catch Michael! I'm waiting on my Video jack to come in as well to give me composite/S-video options.
I may be old school but I am not one room old school..
Can I run the UAV as well as the VBXE simultaneously?
Douglas

Moving along slowly but surely as I have many other things requiring my time. I have found it with my stopping and starting to keep up with my progress to use Michael's PCB Layout and BOM to highlight items that I have soldered in, plus to select my next components to solder based on the preferred sequence outlined by Michael.
where did you get that white motherboard image?

I love it! still some die hard 1020 fans. I have two shrink wrapped in box so I hope the gears held out after all these years.
