dougal22 Posted January 7, 2015 Share Posted January 7, 2015 I got given an Atari STe which was spares/repairs. My intention was to either fix it but if not I would take the TOS 2.06 ROM chips and shove them in my other 1040 STe. I could not switch the ROMS because my working 1040 STe has the TOS roms soldered on the board So i messed around and re-seated some Motorola PLCC and it now boots but with issues A: Sometimes gives lots of screen glitches whilst booting and even once in GEM B: Sometimes won't boot ... will do bombs on the screen and have glitches C: Disk drive will not do anything [ I Checked connections ] D: Sometimes it reads 1024 RAM, sometimes 2048 RAm and sometimes (most times) the full 4096KB Any help would be appreciated Quote Link to comment Share on other sites More sharing options...
ParanoidLittleMan Posted January 7, 2015 Share Posted January 7, 2015 (edited) You should re-seat RAM modules too as first measure. And if possible clean all contacts of socketed chips and sockets.

Yeah I re-seated the RAM. The issues seem to be: Sometimes gives glitches (colors & graphics) Sometimes reads the ram wrong Sometimes puts out bombs during the self/memory test at boot Always: Hear the disk drive spinning and the light remains on but NO clicking of any kind I'll do as you said and clean the contacts etc..

GadgetUK Posted January 8, 2015 Share Posted January 8, 2015 (edited) Probably needs PSU recap as well! Edited January 8, 2015 by GadgetUK Quote Link to comment Share on other sites More sharing options...
locnar77 Posted January 8, 2015 Share Posted January 8, 2015 I was thinking you might need a new PSU as well or recap Quote Link to comment Share on other sites More sharing options...
KLund1 Posted January 22, 2015 Share Posted January 22, 2015 1 or more ram simms might be bad. I had similar issues, swapped out simms for 'new' and all was fine. fyi good luck. Quote Link to comment Share on other sites More sharing options...
