thanks!

PAL.
Anything other than Amiga PAL is playing the wrong way.
Tastes are another matter, there will always be someone who likes to drink bleach.
So the PAL Amiga and more specifically the 500?
I'm in a similar situation as the OP.

If you're in N. America, get an NTSC.
With an A1200 you can switch at bootup and you can modify WHDLOAD games (games cracked to run off a hard drive) to autoboot in PAL or NTSC - your choice. Previous poster says the clock speed is different, which is true, but I've found switching into PAL will slow it down to the proper speed. Easy way to verify is to take a game like Zool, Cannon Fodder, etc, that has a good music track, boot into PAL, and you'll notice it slows down (as does the action).
With a 1084 monitor hooked up, you will also get the extra scanlines of PAL.
Thanks,
I'm in the same position as the OP

Hello,
I love the Amiga (500?) especially the PAL variety.
There are soo many great games for it.
I live in the US and I do have a few Sinclair Spectrum computers that work on my LCD TV with my Scart to HDMI converter very nicely.
I really don't know much..well actually nothing on the Amiga 500.
Is it worth buying? Could I buy a NTSC version and 'convert' it to a PAL version?
Does it have RGB/Scart output?
Is there a way to add modern HDD and add games and programs?
Any suggestions would be much appreciated!

Hello,
Just re-capped my vectrex as well as installed the sound board mod.
I also used a shielded type cable, it wasn't coax because the coax I had, I believe, had aluminum shielding mesh and the solder would not stick(I did find something similar).
My Vectrex is the GCE brand and version 2GE.
The hum wasn't too bad to begin with, so if all else fails I can go back.
From what I understand the buzz or hum doesn't change with volume. So, in my case, low volume the buzz/hum is lower and at higher volume the buzz/hum gets louder.
Wondering if anyone might have some suggestions on anything I can check that may be causing this.
* Just noticed hardware section, apologize for posting this here.

Thanks to ZeroPage Homebrew interview, Matt Smith @mksmith revealed that he's working on a conversion from C64 to Atari 7800 of Ghost's 'n Goblins (2015 version).
Latest wip file (it is even possible to test it online)
Awesome!
Matt is working on the conversion of Night Knight from MSX too!
Thank you very much!
Awesome!

Hello,
I haven't seen an insert around so I decided to make an insert for a Stone Age Gamers NES Clamshell case. The AtariMax cart fits nicely in the NES one.
The file is in PSD or Photoshop and has different layers so you can move, add, delete anything you want.
btw, The dimensions of the insert should be:
12.25" wide and 7.125" tall
Should be all set in PS.
You could probably modify it if you want to make a box(5200 cart box)

Sorry for reviving this post but was interested in the new Concerto Image.
I bought a clamshell case and wanting to make an insert for it.
Can anyone point me to a decent to high quality image of the new Concerto label?

Hello,
Just wanted to make sure that 0.95 is the latest bios file, also I only found 0.94 version for the cbi file.
Is there a version 0.95 for the cbi file?
Also, after using the Harmony programming tool to load the eeprom and then do the copy HBios onto SD card.
I add the .cbi file to root directory of the SD card. Insert SD card into Concerto Cart, insert it in 7800 and turn on.
In the menu do I 'update the bios' using the .cbi file?
thanks,
T

Only the middle IC chip... the Signetics I believe is the brand is a Pokey. The other two are are Antic IC chips used for graphics. And between those brands, I'd go with the AMI over the IMP.
Ahh Thanks CrossBow,
So the CO12294 = Pokey
CO12296 = Antic
Thanks!

Hello,
Going through my spare IC's etc... and found these 3 IC's I believe are POKEY.
I'd like to use one in my Concerto 7800 SD Cart as well as some homebrew games that require a Pokey IC.
If they are all Pokey is one 'better brand' than the others or preferred to use in the concerto sd Cart or Hombrew games with pokey IC's?
Here are the IC's:
Thanks,

Yep, that's a normal factory modification on a 2-port.
Thanks for the reply!
Just wanted to make sure.

Hello,
I'm interested in purchasing Concerto SD-card multicart with empty socket for pokey.
Are there any available atm?

Hello,
Just received an Atari 5200 which is in excellent shape including mainboard.
I'm planning on doing the UAV mod to it.
RF shields were in place and appears that no modifications have been done.
I noticed chip A5 (GTIA)? had pin 11 lifted. Was wondering if this is something Atari did at factory.
It's a 2 port model C021376 REV. 1
Here is the picture:

Don't mean to go on a tangent, what is that blue pcb w/jumpers and wires going toward right side of the case. Scart connector?
And lastly the small pcb with what looks like a relay on it on the left side of the mainboard? (right behind the UAV)

thanks for replies and info!

I seem to remember a caveat about XRam and a Rambo 256k upgrade... IIRC, I think the first bank of extended memory would show a problem even when one didn't exist. Now this makes me want to pull out a Rambo 800XL and test... I will.
See?
thanks for heads up!

Hello,
Are there any plastic clamshell style cases that can be used to store the Harmony cart (or Typical Atari 2600 cart)?
Here's one for NES from Stone Age Gamers:

Not directly. The 9928 outputs Y, R-Y and B-Y. Not RGB. There's a converter out there called TMS-RGB that will do the proper conversion though, and then you get RGBC out that ought to work with this chip.
Thanks for the reply,
I did some searching and found this:
MC13077 encoder It has R-Y and B-Y inputs
Here's the datasheet

If you had the old 64 k chips you could make a 320k memory upgrade combining them and adding support chips for it.... last I knew there aren't any 320k spec chips...
you might go for 128k chips of 256 k chips and make 384k or 512k respectively... though when crossing to 512k you lose internal basic...
yes i have some of the original 64k ones but you lost me after that...
So do all the 256k ram ics stay (x8), do you replace soe of those with 64k?
I noticed before all ram was socketed, all but the 3 closest to the user (upper U's i believe)
Also, I wouldn't be changing anything to the RamboXL pcb would I?
