/****************************************************************************
|
||||||
|
|
||||||
|
Preliminary driver for single-board computers by Synertek/Sym Systems.
|
||||||
|
|
||||||
|
The bottom edge connector is compatible with Motorola's EXORciser/
|
||||||
|
Micromodule bus. One of MBC020's other connectors is claimed to allow
|
||||||
|
"Direct Attachment to a CRT Monitor"; this was omitted in MBC010.
|
||||||
|
|
||||||
|
MBC010 and MBC020 were available with either a SY6512 CPU (-65) or
|
||||||
|
MC6800 CPU (-68), running at either 1 or 2 MHz.
|
||||||
|
|
||||||
|
Though the timing circuit includes dynamic RAM refresh control, the
|
||||||
|
onboard RAM is entirely static (6 SY2114s or equivalent, plus an optional
|
||||||
|
socketed 6116).
|
||||||
|
|
||||||
|
"Sym Systems Corp." may have been a short-lived spinoff or subsidiary of
|
||||||
|
Synertek, named in reference to their SYM-1 SBC. Synertek clearly did not
|
||||||
|
insist on in-house sourcing of the 6500-series peripherals, since their
|
||||||
|
catalog photo of the MBC020 includes a Motorola-branded MC6845 CRTC, and
|
||||||
|
the dumped board has a Rockwell VIA and AMI ACIA.
