Do you know which version of the motherboard that you have (C,D,E, F (285))? That will make a difference on jumper settings and whether you have to do more than just move jumpers.

I soon discovered that I needed to replace the 1.1 ROM and add Extended Color Basic for the purpose or communicating with the drive.  I also read that it was possible to exchange the CPU for an Hitachi and to replace the 4116 RAM with 4164.
