I have come into possession of a gorgeous old 520STFM from a family member's attic - I'm planning to channel some of its retro energy to write an 80's novel on it. It's turning in to quite the procrastination time-sink...
- First off - TV-out was snapped, so I re-soldered.
Then I'm getting a black screen with white border. After extensive googling and testing I realised it was bad memory, and ordered the 4MB upgrade kit on ebay, along with a SM124 monitor.
Fitted the upgrade - finally the STFM boots into GEM!
Now I try loading a disk, only to get the 'drive A: not responding' error. I replaced the caps on the drive (epson 380) with no success - so it went in the bin and I ordered a new drive.
New drive arrives, and now I can finally see the drive in GEM and browse files on disks!
BUT - whenever I try to actually boot into any software / games, I get stuck in a white screen / disk access / restart loop, and never manage to boot anything.
I can't see anything wrong with the PSU, and drive access seems fine in GEM. Anyone have any suggestions for a fix?
Thanks in advance folks!
