[Coco] OS9 68K, MM/1 software and questions

[Zippster]

I don’t really want to change the design (much), at least for this project, but…

The current design uses a keyboard with a PC/AT style connector.  These
are electrically compatible with a PS/2 keyboard, so an adapter could be used,
or the jack could be changed with no difficulty.

The MM/1 uses a serial port mouse.  Many PS/2 mice support working as a serial
mouse (PS/2-Serial combo mouse), and all that’s needed is an adapter plug.

Probably an ATX power supply, yes.

I have to look closer at the video circuitry as far as the VGA.  The DAC can take a different
pixel clock, but I have to see where the clock is coming from, and how it relates to the
rest of the system.  Possibly just a PLL circuit would be needed.
