The board i used was a thing called mac rescue. basically giving more memory and a scsi port. However if you have a strait off 512, ie not a 512e, then you may have a problem where the 800k drive is concerned, as a 512 will not accept an 800k mechanism, anly 400's. if you can scrounge some 128k roms then that will be a good place to start. good luck ay' steveh
