Enduring problems with A1200 busboards

[Stedy]

Hello,

Can you try running the system without the accelerator installed?

Try booting to an early startup-menu and 'boot without startup-sequence' then run Sysinfo, Scout or similar to see if your Zorro boards show up.

My Apollo 1240 refused to boot (black screen) until I did the timing mods.

Hello,

Have you tried adding just a little bit of solder to each of the affected pins (easier said than done I know)?

A bad solder joint gives you many problems.
