Frankie Posted May 10, 2020 Share Posted May 10, 2020 I got my hands on an ATR8000 but unfortunately it doesn't work. You can turn it on, the light goes on, and it hums a little. Now, if I connect my Atari to it and boot it up, the keyboard locks up. No drives attached, just the cable to the Atari. Turn on ATR8000, turn on Atari. Atari boots, looks fine, but no keyboard. Turn off ATR8000 ... keyboard comes back to life. I have no idea what to look at. Here is a quick snap I took with the cover off. Help me Obi-one, your my only hope.

Frankie Posted May 10, 2020 Author Share Posted May 10, 2020 HA! I read the manual! The jumpers where set for an RS232 terminal instead of Atari. When I put jumpers J7 and J10 in the correct place every booted ok. I did a quick LPRINT test in basic and it responded correctly. I also confirmed from the jumpers I have the 64KB version.... Now off to find some drives to play with. 10 Quote Link to comment Share on other sites More sharing options...

StartedWith400 Posted May 13, 2020 Share Posted May 13, 2020 Can you help out a non-ATR800 owner? Can you tell me how R15 and R35 are connected in the circuit? I see them in pictures but they are the not in the online schematics. R15 is a 10k near U25, the CTC, and R35 is a 4.7k near U49. The disc capacitor(s) near the SIO connector aren't in the schematics either - and they changed from rev. B to rev. C. Quote Link to comment Share on other sites More sharing options...
scitari Posted May 13, 2020 Share Posted May 13, 2020 I have several of these. Finding drives is easier said than done. Quote Link to comment Share on other sites More sharing options...

I would if I could, but I have no idea how to do that and I’m guessing I need some hardware for it. Quote Link to comment Share on other sites More sharing options...

If you can get into DOS, you should be able to do it with the DOS debugger. Let me see if I can't find you some instructions. Quote Link to comment Share on other sites More sharing options...

Jeffrey Worley Posted July 7, 2020 Share Posted July 7, 2020 I have an ATR8000 on the way, am very familiar with it in its standard and copower configurations, but the one I just bought does not have boot floppies. Can anyone send me the CP/M disk for this machine? Best, Jeff Quote Link to comment Share on other sites More sharing options...

If I were you, from considerable experience with the ATR8000 and with the COpower, I would replace every electrolytic on the boards. I long suspected mine for crappy electrolytics as far back as 1987. I'm not one for 'recapping', but SWP did use crappy caps and it will cause spurious drops in communications with the copwer (crashes), as well as crashes just running CP/M.

svhovater Posted July 14, 2020 Share Posted July 14, 2020 Jeff - send me an email (svhovater@gmail.com) with your mailing address and I'll send you what I have. My ATR8000 is boxed up, no floppies. ;( If the disks are still readable, copy and send back please. cheers Steve 1 1 Quote Link to comment Share on other sites More sharing options...
