I was going to keep all my compact restoration questions in one thread, but then I thought it might be easier to get answers if I break them up.
As mentioned in an earlier thread, I have a 512K board upgraded with snap-on RAM and SCSI boards, I think both from Dove MacSnap. Either it or the analog board (or both) were not working when I pulled them from a non-working 512Ke some fifteen years ago. Picture of all three:
Can I put these boards in the dishwasher without removing any RAM or ROM chips? The RAM is soldered on and the ROM is socketed. They are really dusty and cleaning with alcohol and rinsing lightly definitely didn't remove all the gunk.
Sadder news:
While trying to straighten the pins on the SCSI board (the ones that plug the ROMs into the socket below) I managed to break one off and it went flying (so I don't have the pin to solder back on). Second row from the bottom, second pin in from the left.
Is this fixable? What, if anything, could I do to replace the missing pin? I don't care that much about SCSI on this machine but not knowing exactly how the upgrade worked, I am not sure what to do to undo it apart from moving the socketed ROM chips back onto the main board. I don't even know how much memory this was originally upgraded to - if it has the SCSI maybe it has 1 MB? Strangely, I see no sign of a SCSI cable having been run to the outside of the machine.
I don't have any grand plans for this machine since it has never been working since I got it, but I thought it would be fun to get it back into working order.
