+Al_Nafuur Posted October 19, 2020 Share Posted October 19, 2020 (edited) The 7800 crashed after a few minutes, and when I restarted it it started with the inbuild Asteroids. So I pulled out the Cartridge and removed @Andrew Davie's beautiful 3D printed case and plugged in the naked PlusCart PCB into the slot. I think the cartridge slot and contacts needs to be cleaned..

Working with the 3D printed cartridge case off likely means the case is a bit too thick for the slot holder. Some 7800 console slot holders are slightly narrower than others. It's enough to give 3rd party cartridges such as Imagic, that are a tad bit thicker than the Atari first party standard, a tough time to work, if at all. You can try shaving the cartridge holder sleeve, or take an exacto knife to the sides to widen/loosen the grip, inside the system. Or see this as an alternative 'fix': 1 Quote Link to comment Share on other sites More sharing options...

marauder666 Posted October 21, 2020 Share Posted October 21, 2020 I've just received another PAL 7800 to video mod, its the same revision board as mine, but the OS ROM is an EPROM, doesnt seem to have been opened before so is stock. Doesnt have the embossed Atari logo on the metal strip, its just screen printed. W5 jumper is set differently to the others I've worked on. Thinking this has a different OS revision. PCB date code of 3293, long after the 1 January 1992 date supposedly all 8 bit Ataris were discontinued. Will be able to test the Pluscart on this one on Saturday when its working. Wish I'd seen the above post before I'd stripped it down. 3 Quote Link to comment Share on other sites More sharing options...
marauder666 Posted October 24, 2020 Share Posted October 24, 2020 (edited) Pluscart works on this PAL 7800 with the EPROM. Edited October 24, 2020 by marauder666 1 Quote Link to comment Share on other sites More sharing options...
juansolo Posted October 24, 2020 Share Posted October 24, 2020 (edited) That's potentially interesting. So not only is that machine dated after the 7800 had supposedly finished production, it has the C300558 bios EPROM which as far as I can tell is the prototype Asteroids bios that can also go into an NTSC machine... http://www.progettoemma.net/mess/system.php?machine=a7800 EDIT: I take it back, that's the same number that's on our ROM chips in both our 7800s. Damn. I'm going to take over a load of my carts on Weds to see what does and doesn't work on it.

+Mitch Posted October 24, 2020 Share Posted October 24, 2020 The last batch of PAL 7800s was assembled in August of 1993. It looks like the one pictured is one of the final batch. Mitch Quote Link to comment Share on other sites More sharing options...

+Mitch Posted October 24, 2020 Share Posted October 24, 2020 The 7800 was cancelled in 1992 in North America and most of Europe. Atari UK continued making 7800s into late 1993. Mitch Quote Link to comment Share on other sites More sharing options...
