I found a strange looking computer today. It's a
Grid 1535 EXP computer and
it has a extra pod that clamped on the computer. The pod contains a HP-IB
port. There an empty slot to the left of the HP-IB port, what's it for?
There's also an empty hole roughly 1 x 2 inches next to the power connector
on the laptop. Is that where the battery is supposed to go? I also got a
extra battery pack that also clamps to the outside fo the computer. Does
any know the specs on this computer? It has a co-axial power connector.
What voltage and polarity power does it require? What's the story with the
HP-IB port and how do you access it?
Wow, it sounds like somebody just lost their GRiD-virginity. John H. took
my 1535EXP, so I have to go from memory. It's a 386DX-33 (in a PGA, so
you can upgrade it via Cyrix/TI/etc) with up to 8MB RAM (low-profile
SIPs). I think it wants 16-18V DC, center neg. The empty hole will
accomidate eithe battery or a power supply with an AC plug.
The GPIB was probably intended for compatibility with earlier GRiD
peripherals, and will be automatically detected by IntegGRiD, a version of
GRiD-OS that runs on top of MS-DOS.
The connector on the bottom of the machine plugs into a docking tray,
which John H. also took and I think was trying to sell last time I
checked. (John, are you there?)
