Thanks for that. SCSI comes in more flavours, as you can seee here: http://en.wikipedia.org/wiki/Scsi#Parallel_SCSI

But judging by the years in that table, the only SCSI standard that ever existed in 1993 was SCSI-1 or Narrow SCSI.

The adapter you were talking about, did it look like these?

The RAM card. Should I understand that the computer could theoretically use even 128 megs or more, but there were no such cards made? Because I wouldn't mind asking for a custom version with more RAM on it from some company.

The floppy port. Is it the same connector with the CD-ROM connector? From what I can see here

the floppy connector on the back is the same with the CD-ROM one, but the pinouts could be different indeed.

Thank you so far
