New Mystery Boards

[Jeff Lemke <lemke@terra.cira.colostate.edu>]

I have come across some Apple II boards in an archeaological dig this
weekend, (with no documentation of course), that I'd like to find out
the specifics of, or just what they're for in some cases.


Board 1:  Dated 1982
"GSP" is silkscreened in large letters in the upper left.  "Artwork
PC19845, Rev. B, Model GTP-245" is written on the other side.  There is
a Z8530PC chip on the board, and two 25-pin cables coming from "Port A"
and "Port B".

Board 2:
There is a 34-pin connector, 8 LED lights in two pairs of 4, numbered
1-4 and 5-8, and 4 DIP switches.  Board is labled only with "FAB 830125
Rev. B".  A modem card?

Board 3:  Very unusual looking.
Labled as "MMI DAC Board, Temporal Acuity Products Inc."  There are RCA
"Spkr. Out" and "Aux. Out" jacks, and a long sliding lever on one end of
the board which I presume is supposed to stick out of the back of the
Apple through a slot.  Obviously this is some type of sound board, but
if anyone has any more specific information, please fill me in.

Board 4:
Labled as "Voice Input Module" by "Voice Machine Communications".  There
is another daughterboard (but not piggybacked) connected to this board
by two 16-pin cables.

Board 5:
This is the only board that's fairly straightforward in purpose - it's a
Titan Technologies "Accelerator IIe".  Does anybody know how it compares
to the Applied Engineering accelerator for the IIe?
