Heres the unboxing photos, the original owner used it for one project
and then boxed it up and put it away, he even went as far as removing
the winchester hard drive and put it in its original box. I had to
Odd...
At lest these DEC desktop machiens are easy to dismantle into modules.
The downside is that they are very hard to repair, getting a test probe
onto the right point can be 'interesting'. I remember having to sort out
a bus arbitration problem in my 'Bow... I had the mainboard on the hench,
the PSU upside-down alongside it. the fan bracke sitting next to that (to
provide the mains on/off switching, etc).
Do you have any other expansion options other than the hard disk? The
graphics card is quite nice (I always fount it curious that a machine
called a 'Rainbow' was actuall a monocrome machine in the base
configuration). An add-on RAM card is nice to have too, there are at
least 2 versions. One gives 192K (and has 3 soldered-in banks of RAM,
64K*1 chips), the other has socekted RAM and can have either 64K or 256K
banks (I think just about any mix is possible).
install the drive, give it a good firm wack because
of stiction and
reinit the drive, but its fully functional, The only thing I can
think of using it for right now is a VT100 terminal to my Mac like I was
doing with the Apple IIc
As others have said, there's both a Z80 and an 8088 in there. It will run
a non-PC-compativle MS-DOS and an odd CP/M that will run both CP/M 80 and
CP/M 86 programs. It's not a bad CP/M box, actually.
