Yep, I am here asking you guys for advice about my A4000T, which doesn't boot.
I have been preparing it for sale to fitzsteve and going throught the drives, floppies, ZIPs etc to clean out persoanl data and format disks.
Everything was going fine yesterday: working CD, working hard disk with brand new OS3.9 boot, PPC running fine and all was good. Started putting all the zorro boards back in, starting with a DKB which went in fine.
After putting the PIV in slot 2, the Miggy would not boot, and that is how it has remained despite trying a lot of things:
Tried two different PSUs: one ATX with AT converter, one AT
Tried all three CPU cards: PPC, 060, 030. The machine powers up with all three, and responds to reset. On the 060 there is the familiar rainbow flash that you see every time you start. Tried different RAM on the 060 and PPC.
Tried two different disk modules, tried two different A/V modules.
Tried with and without the ports module.
Tried with floppy only, with no floppy and with various disks.
Took the mobo out of the case and looked for bad contacts, bad caps, broken traces. Can't find anything obvious.
Tried different SIMMs on the mobo
Cleaned all the zorro slots
Tried a different SCSI cable
So I am pretty much stuck. I haven't tried different CIAs as I don't think that's the cause. Not sure about that. They're socketed but will be difficult to remove.
Any ideas? :confused:
