but I am curious about it. I'm especially curious about the memory. If
his recollection of the memory options is right, this thing supports
34MB or so. How is that possible on a 286?
Time to dig out my PC Tech Journal product guides.
Well, I see a System 5000 and a System 6000 in the 1988 guide and
only the System 5000 in the 1987 one. Both are described as follows:
System 5000
Multiuser, multiprogramming Memory: 512K-16M
CPU: 80286 Graphics: Monochrome, Color
Interface(s): 1 RS-232C, 1 Centronics
Units sold: 5,000 since 1985
Cost: $2,450-$3,895
There's also a System 6000 with the same description but for:
Units sold: 400 since 1986
Cost: $1,595-$3,005
The 1985 issues of IEEE Computer contain a couple of product
annoucements for the System 5000, but nothing more recent.
There's a System 3000 box in the Freeman PC Museum at
http://www.pcmuseum.net; just select "Micro Five" from the
"Manufacturers" search box.
A little web research shows that the company hit hard times around
1987, ultimately being acquired by Samsung in 1988. Their chairman
during that time appeared to be a "turnaround specialist" who later
went on to head up Pick Systems.
That's all I've got here. I suspect that those memory expansion
slots could accommodate 16M tops. Another remote possibility is that
they were LIM/EMS type memory or that they were otherwise
bankswitched.
