Took out MB and took this photo of back. Note the battery area but also the attached wire on the bottom right, some kind of trace repair?
(Battery is top, just left of center)


Hi!
Had you check the TICK signal from de PSU?
Try start up without this signal from the PSU, only changing the J300 jumper position.

I had this same problema during my PSU MOD adapting a PCAT PSU.

Tried the j300 jumper, no luck.
Looks like I might piece this thing out, not worth the money to fix.

I have tried:
Disabling rom swithcher and using one rom
Removed Megachip and used just the agnus
Reseated cpu and most chips
Cleaned as well as possible
All with just psu and floppies attached nothing more


Could you tell if the Power LED or CapsLock Led blinks when you power on the machine?
