If you're still keen, I've found the details from my original job sheet.
Specs are:
030 @25MHz, OS 2.05 in ROM, 2Mb chip, 4Mb fast.
Other notes say it has a hard drive which appears dead. Floppy drive works OK, but there are mechanical problems with the front case and eject button.
Is there an A3000 which *didn't* have this problem? :-)
All my keyboard adaptors appear to have been used up, but if you can find me a PC keyboard which has a 5 pin DIN connector, I can program a micro (about $18 each) and fit it inside the keyboard to make it Amiga compatible without the need for external adaptors.
Keyboard needs to have the window$ keys, as these are remapped to become the L&R Amiga keys. See, and everyone thinks those keys are useless :-P
