Today I have for sale a very good-looking Amiga 500 Plus rev 8A board. This is a full rev. 8A board with battery (removed), RTC and 1MB chipram.
Here is a story.
Prologue:
I received the board with a description: not working, greenscreen. The board was very clean without any signs or dust, rear connectors are so nice that I had a temptation to canibalize her for my next A4000D build. Chipset parts are black with shinning legs and without scraches. Must have been stored in a boxed case or somebody cleaned it precisely. Battery was removed. Signs of battery acid on 74LS244 buffer near battery.
Repair:
I didn't even try to turn it on before repair. I used an ohmometer to find damaged tracks. There wasn't any of them near battery but there was teardrop of acid between Gary and Even CIA. That was it, the via running _VMA signal near R712 resistor was non-conducting and this signal is necessary for board to boot so this was at least one of greenscreen reasons. I repaired it almost invisibly using a piece of tinned wire through the via. Didn't find any more damaged tracks, nearby vias are OK and look clean. Then I washed the whole board to neutralize the acid and dried it for several hours on a radiator. I also removed battery legs and cleaned battery pads.
Epilgue:
I connected the board, and the board booted to a well-known Kickstart 2.0 screen. I connected the Flashfloppy/Gotek drive and ran AmigaTestKit. I made all of necessary tests and made photos of results. All PASSED. Then I started Cannon Fodder and played 45 minutes until Jools and Jops died both at the same time killed by enemy grenade...
Ah, the board is not recapped, with original Shoei capacitors. In my opinion it was untouched by soldering station except the repaired _VMA track.
Price: 240 EUR (was 260 EUR)(was 290 EUR) + shipping
Currently shipping only to EU countries to avoid export problems.
Shipping via DPD courier service is around 15-30EUR depending on distance from Poland.
Edit: Price drop!
