TempterOfFate Posted August 9, 2021 Share Posted August 9, 2021 Hello, I upgraded my Atari ST's CPU from a 68000 to a 68010, I unsoldered the old CPU and put a socket in its place, I checked, the continuity is fine to other chips on the board, the 68000's pins got bent when I removed it, and it's a machine pin socket, so it won't really go in, so I can't test that. I get no activity on anything after the CPU upgrade, I've had the machine on for a few minutes now. Just a white screen. No floppy seek, no access on the UltraSatan. Nothing happens when I put a floppy in the machine. Help would be appreciated. Quote Link to comment Share on other sites More sharing options...

TempterOfFate Posted August 10, 2021 Author Share Posted August 10, 2021 I've been working on this for a few hours now, patch wires to GLUE, ROM, and MMU are done, there was a problem with the A3 pad Had black alternating lines and then that went away after I patched to the MMU Back at white screen.

ParanoidLittleMan Posted August 10, 2021 Share Posted August 10, 2021 68010 needs TOS 2.06, or patched TOS 1.xx , because different stackframe. 1 Quote Link to comment Share on other sites More sharing options...
TempterOfFate Posted August 10, 2021 Author Share Posted August 10, 2021 That'd do it. Thanks. I knew I was missing something. I'll put a 68000 back in when I get a new one. Quote Link to comment Share on other sites More sharing options...
