;-) Clearing the snow from my glasses, I saw John
Higginbotham typed:
Snip!
Supported or possible??? There's a big difference, you know! ;-)
Supported IIRC is only 300 (maybe 600) bps for the CoCo2, and 1200 for the
CoCo3. I do remember many ads (adverts for our British friends, IIRC)
claiming flawless 1200 (coco1/2) and 2400 (coco3) bps speed for a CoCo.
Again, IIRC I heard rumors of someone actually getting 9600 bps thru the
bitbanger, but I'm sure that's will all interrupts fully disabled in RSDOS
with a memory-to-port (or vise-versa) transfer only -- no other functions
like video, disk or anything else so you were xferring totally blind.
True, the major problem was in how much data 8bit CPU can move
without falling back.
Big snip!
All plug-for-plug compatible with our beloved
