I'm working on supporting GPIB tablet support for PERQemu (right now it
only supports the 3-button Kriz tablet). Anyone have documentation for
the protocol used by the GPIB variant of the Summagraphics Bit Pad One?
I've found documentation covering the Bit Pad Two
(http://www.calcomp.com/files/Bit%20Pad%202%20Tech%20Ref.pdf) , which
appears to be RS-232 only. I'm sure the protocols are similar, anyone
know for sure?
Thanks,
Josh

Not suprisingly (as a PERQ-fanatic :-)) I have the excellent user manual
for the Bit Pad 1, which contains full schematics and protocol
information. From waht I remember, the BP1 came in RS232 and GPIB
versions, and the data protocol was the same.
If you get no other replies I'll dig out the manual and type it up.

Looks like a pretty simple protocol, should be easy to get going, at
least once I work out the subtleties of GPIB...
(I almost have Accent booting... so very close...)

Yes, thanks to Al for that. It's saved me a bit of typing...
through the trouble of transcribing it for me. Thanks

IIRC you don't need to bother too much about GPIB. On the PERQ side that
was handled by the Z80 and a 9914 chip. And I don;t think the BP1 uses
many of the GPIB features, thankfully.
