New toy, HP Apollo 4500, and it's broken... - test-drb@ccmp.vtda.org

13 Jun 1998

This is somewhat tangential, but I suspect whoever is
reading about HP Apollo's may be able to contribute.

I came across a rack mount system in the local surplus
store.  The faceplate reads "HP 2100c Programmable 
Microcomputer System".

Any ideas what this is?   Worth picking up?

 <I got a apollo 4500.
 <It has a 68030 inside, and a 700-someodd meg MFM (?) harddisk.

 More likely SCSI (single 50pin cable) or EDSI (two cables like MFM).  
 MFM drives topped out at 160mb or so, EDSI went to at least 400mb maybe 
 higher. 
Definitely ESDI or SCSI.  Although they could have had SMD or ESMD
as well.

 <I have no idea what it runs.  This one has a SummaSketch pad with it.
 <It was used for CAD stuff.

 Some kind of unix. 
Possibly, though the Apollo's ran Domain/OS  which was Multics inspired 
but later it went to BSD compatibility and looked like both Unix and
Multics.

Actually, there are a lot of Apollo collectors out there and the video
card may be getable.  The Apollos used 3C505's for ethernet and some other
Token ring interface.
