Wow, at least I have shown that the standard version still fits under the shield in a 600XL (after a maniac work BTW).

 

 

 

 

That is info I was looking for:-) What specific work btw?

I would definitely co-financing a project with the goal to have an A8 keyboard PCB hosting modern keycaps in our beloved A8 style.

Since I have no design skills I can only offer additional financial support to help kick-off such an endeavor.

100 hundred keycap sets target mentioned previously looks doeble.

[Need BASIC ROM Chip, Or Compatible EPROM]

That is exactly PCB that I have. Thanks for jumpers photo. I have TL866 programmer too. But I have also ordered this https://oshpark.com/shared_projects/MjBJtpCb

Not sure which option I will choose. Thanks to all. Rev C is going in there.

[Need BASIC ROM Chip, Or Compatible EPROM]

Nice but I do not want any additional switches, holes in case. I want to keep my 600XL in original purist shape, only better.

 

I was under impression that it is safe to choose any of the three BASICs. But I will stick to Rev C. then.

I only plan to write very BASIC programs with #FujiNet, to do some simple socket communication, when folks developing #FujiNet are that far.

[Need BASIC ROM Chip, Or Compatible EPROM]

Still I am puzzled. Are there any incompatibilities? Is it better to install ATARI BASIC rev C, TURBO BASIC XL or ALTIRRA BASIC? Which one should I choose? I have Rev B currently.

[Number 1 Atari item you have too many of...]

When I had three 800XLs two years ago I sold one.. guess I am not that bad hoarder. Still I have one too much.

[Number 1 Atari item you have too many of...]

When I saw topic title I was asking myself if such  a thing is possible. Now seeing what you have... I have only one:-( I envy

[New addition to the family: 600XL with supervideo mod and 64kb of ram? B/W...]

Thank you it worked very well. I uploaded some pictures here

 

[How many mods will fit in a 600XL?]

I did UV mod 2.1 (partially). It greatly improved picture. Now even CRT TV input is VERY good. All the noise is gone and sharpness is greatly increased. I replaced  L14 with 3.3Ohm resistor, C115 with 220uF, and connected  pin 1 through resistor 75 (two 38 in series) and connected pin 5 through resistor 100 ohm. See in picture where I connected them. Do not forget to to apply also point 3 from UV mod - cut the foil on bottom side.

[New addition to the family: 600XL with supervideo mod and 64kb of ram? B/W...]

Cool, thanks. It looks like L14 has been replaced with resistor, C115 is bigger now and C109 has been removed. I am gonna give it a try. I do not see S-Video brought out on you board. Maybe it has been done from solder side.

[Atari 800xl - bargain or steer clear?!]

That did not last long haha:-)

[New addition to the family: 600XL with supervideo mod and 64kb of ram? B/W...]

Could you post more detailed picture(s) of video area? Right now I have another PAL 600XL on the desk and I am trying to make video better. See in neighbouring thread (how many mods..) I would like to know what needs to be altered in a PAL machine with monitor out.

[How many mods will fit in a 600XL?]

I have an unmodded PAL, with 16kB RAM. On CRT composite is quite good, but TV signal is noisy. On LCD not even composite is good.

Sorry for my totally off topic yell:

 

The 600xl absolutely kicks ass!!!

 

I love it. Mine has the Hias 576k sram upgrade, a built in rtc, and dual os (stock and mybios). I fixed video output by removing one single disc capacitor. This is one of my most favorite atari 8bit machines.

@Marius which disk capacitor was it?

 

Another question, does wiring S-Video require more than two new resistors?

[What are Atari's selling for now please..]

As soon as we happen to have more than ONE 800 or 130 or so on... we are hoarders. Face it:-)

- 74HC574 chip (latches part of the address),

- GAL16V8D system,
- flash memory SST39SF020 (512kB -> SST39SF040) or e.g. Winbond W29C020

LED1 and R5 resistor are not needed for operation. They were only for diagnostics, but the project turned out to be fully functional, so ...

 

how to do it?
- we create games / programs (.xex) into the sets of CreaXin1 (save as .rom),
- we combine sets with the XEGS Merger program,
- we program GALA (the input from the CPU is also included) and flash, eg with the TOP3000 programmer, possibly TL866, etc.

I managed to buy two sets from Poland. Could you please also post (link to) equations and/or Jedec files for GAL?

[Does anyone make new Atari 8-bit cartridge shells?]

Are those PCBs public or can I order from someone? I would love some cartridge(s) for my 800XL

Could not resist..

Awesome. Waiting ..

[New SDrive-Max stopped powering on.]

Should not be Uno tolerant to having both power sources at the same time? Anyway new Uno costs few bucks. But try reflashing first.

[What Atari item do you wish you had?]

Just a bog standard 130XE with XF551 also standard, no speeder or similar. But the prices went insane...
