A500 main board revision ID

deimos · 12 January 2022, 18:23

I've looked all over my 500's main circuit board, can't see anything that gives it's revision number. I was expecting something to say "Rev 6.1" or something similar, but nothing.

Am I looking in the wrong place?

Art least the later rev.5 and 6 A had it printed, earlier probably not. Check here: http://amiga.resource.cx/photos/phot...es=med&lang=en or: https://bigbookofamigahardware.com/b...duct.aspx?id=8

Thanks. Mine looks most like http://amiga.resource.cx/photos/phot...res=hi&lang=en , with no revision information in the big empty space on the right hand side. The most obvious difference is that mine doesn't have the OPC bit in the silk screen in that area.

I don't know if "FAB 312512" means anything, but mine also says that like that photo.

A lot of the chips say 1387, so I guess this is early, but not super-early / collectible?

312512 is Rev.3 or earlier...

The revision is written on the underside in 3 and older.
