Hello all,
I recently got a bare Wavemate Bullet board, and would like to get it up and
running. I received some 8" floppies with it, and they appear to be boot
disks for the board. All but one was readable on another CP/M system.
I'd like to get docs for it, or pointers to more information on the board.
It's a Z-80 based board, and has the CPU, DART, CTC, DMA, and PIO chips.
Looks like it has some RAM (16 MB8264), and some glue logic, plus a
Fairchild MB8877.
It is labeled "Wavemate (c) 1981 Rev. B Hawthorne, CA. Made in U.S.A."
There are two 10-pin headers marked "J3" and "J4", two 50-pin headers
marked
"J1" and "J6", and two 34-pin headers marked "J2" and
"J7". I suspect J3
and J4 are serial I/O, as the traces go to a set of 1488/1489 chips. J1 and
J2 are next to each other on the right of the board, and J7 and J6 are next
to each other on the top of the board. There's also another 34-pin header
near the top right marked "J5". There's an 8-position DIP switch labeled
"SW1". Power appears to be from a plug that loks like a typical PC-style
drive power connector. I'd like to verify the pinout, though, if possible
:-)
Rich, I have some docs for it - about 10 pages - that I will mail
you given an address. But in the interim, here is some
information that may be useful:
J1 Bus extension
J2 Winchester Interface connection to an IMI 7710
Winchester controller or equivalent
J3 Serial port
J4 Serial port
J5 Parallel printer port
J6 8" floppy drive
J7 5.25" floppy drive
J8 Power connector 1,2 NC, 3 Gnd, 4 5VDC @ 1.5A
DIP switch - 8 position is used to initialize the FDC
SW1-5 SW1-6 SW1-7 SW1-8
SDMini off off off off
DDMini off on off on
SD8" off on on off
DD8" on on on on
That ought to get you started, anyway.

Curiously, there's no EPROM, nor even a socket for
one. My luck, it's some
missing part :-(
The boot program is 32 bytes in a ROM. Tiny!
I'd appreciate any help!
Thanks,
Rich B.
