Lots of unhappy memories of this model, and not for the reasons you might think!
Built to withstand just about anything, this was a very robust and heavy early Server grade machine.
The first of these I touched was absolutely fine, and was at my old Secondary School when I was helping out with trying to recomission an ex SIMS Server running Netware 286ELS for use in the School Library.
I seem to remember it had a 286 CPU and 16Mb of RAM. I can’t remember the size of the HDD for sure but I don’t think it was much bigger than 120Mb. The School server also had a Token Ring Network Card for connectivity to the LAN.
In later years I ran up against these machines running SCO XENIX. These were installed at a customers’ site, and had in all honesty been run well beyond the realistic end of their working life. I’m not sure if these ones had 286 or 386 processors, but they had an internal Tape Drive fitted which was somehow connected to a second Floppy Drive Controller card, and was recognised by SCO Xenix.
My unhappy memories stem from the problems we had with sourcing replacement hardware when HDD’s failed etc. I even remember an engineer (not me!) physically breaking a customers’ most recent backup tape as he was trying to restore it in one of these machines!
