   THREE of my friends bought 6300s. They were GREAT compared to the
Sanyos. They actually had ISA expansion slots instead of the ONE
propriatary connector that the Sanyo had. They would run true IBM PC DOS
and all the IBM PC software. I don't remember exactly what speed they ran
at (6MHz?) but I'm pretty sure that it was faster than the PC (plus it used
the 8086 processor). The Sanyo ran at 3.58MHz (8088) so that they could use
CHEAP color burst crsytals for the oscillator. The Sanyos also used part of
the main memory for the video memory instead of having video memory at a
fixed address ala the IBM PC so a LOT of the MS DOS software would not run
on it. The Sanyo had about a 30 Watt power supply, you literally could not
run an 8087 coprosessor and a 2nd floppy drive at the same time! The Sanyo
could not be expanded over 256k without serious hardware hacks, etc etc
etc. The **&*&) non-standard keyboard and keycodes, non-standard IO
connectors. I think everything was non-standard on it! The DOS for the
Sanyo was highly tailored for it and it was FULL of bugs and the manuals
were plain S**T!  Like I said, I HAD a 555. It was THE worst compatible
computer ever made! No make that plain WORST computer ever made. I don't
believe any other computer had as many problems and as little support as
the Sanyos did! I had friends that had Columbias, AT&Ts, and just about any
other that you could name and none of them had a fraction of troubles that
I constantly had. I was a poor college student and could afford anything
else so I stuck with (or got stuck with!) a Sanyo for three years and I
used it A LOT. I DESPISE the things!
