Trying to resurrect an A500 motherboard
« on: March 03, 2012, 11:53:14 AM »
Its a Rev 6A motherboard i have spare. 512K Chipmem and 8372 agnus A500.

It goes through the grey check/test screens and gets stuck on the last grey screen.

I tried replacing Garry and Paula and tried another Kickstart but same results. Traces look good though i did not test them and motherboard is pretty clean.

I also tried an A500+ 2MB Agnus but that did not work. Just got a black screen. I also tried pushing down the socketed chips and switching the CIA's.

Any ideas what i could try ?
A1200HD- Blizzard 1230IV / 64Mb / Kick 3.1 / OS 3.9 / 20GB HD
A4000 040 @33Mhz -Kick 3.1 / 16MB
A2000 Rev4.4 - \'030 @25Mhz / 8MB / Kick 3.1 / ClassicWB
CD32 -     Stock (W/ 2 CD32 Controllers]
A500 Plus - 68000 / 2MB Chip / 2Mb Fast / 2.04/1.3 / A590 / A570
