I know what one is but not where to get one. The ACIA is a particular
variety of UART. IIRC, it stands for Advanced Communications Interface
Adapter or something similar. Should be a variant of 6550 chip in there.
Since I have a small drawer of 6550s (stripped from some 1970s 6502-based
dumb terminals), I'm wondering if there are plans on the net (ftp.funet.fi?)
to build one.
I happen to already have an IDE interface for the C-64 (and a 1.3" KittyHawk
drive to go with it); I'd love to stick a browser on there and go. If
possible, I'd probably try to retrofit an ACIA to a recycled C-64 game cart
with some creative wiring. Presumably at low speeds, DMA is not required.
As they say, it's not how well the bear dances, but that the bear can dance
at all.
Great Job, Cameron! Let me know if it's possible to homebrew a serial
interface that's compatible with what you are working on.
