  Shannon,
 There were at least two computer models: 5322 (all-in-one) and 5324
 (screen plus deskside), three printer models: 5217, 5241 and 5242, an
 external dual 8" diskette unit (5246), and a networked floorstanding
 fixed disk unit (5247).  IIRC, the 5324 computer and the 5247 disk unit
 looked pretty similar except that the computer has floppy drives.  The
 disk unit was available in at least two variants - 15MB and 30MB.
 My first draft of this message suggested that you try using the search
 term "system/23", but I tried it, and it doesn't help. :(  I'm guessing
 the narrow market segment and relatively short life span, plus IBM's
 copyrights and such, are the cause.

Yup, that's exactly what I was looking for and could find no mention of.
Not even on wiki's or classic computer directories that I could find
talking about the Datamaster system. Usually they just say that an all
in one predecessor of the PC called the Datamaster or System/23 was
released months before the PC release date. I can't even find pictures
of the 5324 unit, which is what I have. Just wish I could get this thing
to boot. I think I may have corroded connections or something.
So, is the basic in ROM? Do I have to have a system disk to get this
thing to work?
I really appreciate any additional information on this, and maybe these
answers will help someone else too.
Thanks
Shannon
