I'm going to stand by my assertion that the Softcard was a single-board
computer on the technicality that it did have its own RAM - you apparently
forget that registers are a form of RAM - HA! They're memory, they're
addressed over a bus (that just happens to be within the microprocessor),
and you can directly access any register at any time (random access). As
for I/O, that's what the Apple ][ bus was for, right? As Opus from Bloom
County, among other comic characters, was known to utter,
"PBBBBBBTTTTTT!!!
Heh. Nice attempt at hair-splitting but I think you missed. ;-)
For those that cited the Amstrad systems, I was referring to the S-100 and
Softcard timeframe.
But you didn't _say_ that.
CP/M was only provided with the Amstrad CPC664 and
6128 floppy-disk based models, and the DDI-1 disk expansion unit for the
464 (only CP/M 2.2 with the 664, and 2.2 and 3.1 with the 6128).
Nope. It was an option for the CPC series of colour-capable home
computers, yes. But it was supplied *as standard* with the PCW 8000 &
9000 series of monochrome-only "personal computer wordprocessors". You
got 2 boot disks in the box: one with LocoScript, the dedicated
Amstrad PCW word processor (albeit later ported to, or rather
rewritten, for IBM-compatibles), and one with CP/M 3.
CP/M was the _only_ general-purpose OS for the PCWs. (Excluding the
later, unsuccessful, PcW 16.) They had no ROM and no ROM BASIC or
anything else.
I think they were the last CP/M machines of any significance, first
released in 1985, well into the MS-DOS era. Nonetheless they were
hugely successful in their time and there were quite a few CP/M apps
released that only ran on the PCWs, directly driving their 720*256 res
screen in graphics mode or a few in 90*32 text mode.
