Apollo DN5500 refurb suggestions

Show all headers | View raw

I just acquired an Apollo DN5500 (including keyboard and mouse) that has
been in storage for on the order of 25 years.

Is there anything I should do specifically as I start to refurbish it? (I
don’t have the machine here at a moment, I need to clean it thoroughly
before it’s allowed in my home…)

1. I assume the hard disk is not SCSI, and will have a (very) limited life
if it starts up at all. Should I expect it to be MFM or ESDI? How should I
go about imaging it?

2. I assume Domain/OS 10.4 won’t run on it, which is the only OS that I
have handy since it was put on Bitsavers. (I might have a line on a source
for 10.3.5 though.) Any suggestions for how to find an OS for it? I assume
what I should do is get 10.4 running on my 425t or 433s, and then net-boot
an older OS on the DN5500. Is that something that should work?

3. I assume it doesn’t use standard 30-pin or 72-pin SIMMs. If the RAM in
the system does work, and is something like 8MB, should I even bother
trying to expand it?

Anything else I’m missing? Anyone have a line on a service manual or
anything like that? Or ATR cabling/routing/bridging?
