I was on Ohio Scientific dealer. Here is our 6502 C2. You added the
DUAL 8" floppy drives in another box. Video was TV!...no graphics.

If you go to Mark's Lab:

You can download the OSI Emulator, which will turn your Windows machine
into an OSI Cx computer circa 1975, complete with OS-65/U operating
system and OSI extended BASIC in virtual ROM. Take a step back in time
and test your skills!
You can also download the ORIGINAL OS-65D V3.3 disk images for your 8"
6502 floppy drives....one of the first disk-based operating systems for
microcomputers.

This is our first home computer, the C2 Challenger II. Tape programmed
MUCH faster than Radio Crap's TRS-DOS with TV output you could plug into
any TV video port or use a TV RF modulator. No monitor to buy, if you
couldn't afford one.
Wow...I'd forgotten our retail prices...(c;]
Here's a great page to show our stuff:
http://technology.niagarac.on.ca/peo...cientific.html
Look down this page and you'll see a two-cabinet computer with serial
terminal and big white 8" disk drive. That's the beast...The Challenger
III, the FIRST commercial microcomputer with a HARD DRIVE! The drive, a
74MB, 14", 4-platter monster stolen from the mini-computer market, was a
$6000 ADDON! The Challenger III had THREE processors, a Z-80 for CP/M,
a Motorola 6800 and our usual 6502 running OS-65/U with extended BASIC
that actually supported the hard disk drive noone else had. Want to
boot another OS? No problemo! Just flip the switch to choose your
processor and click the big button on the front to REBOOT from your
floppy!
My partner and I wrote several BASIC systems and sold them as packages
to small business. Our vending machine accounting system was still in
use as late as 1989 in several places. OSI had a vendor for general
accounting on it. Sold quite a few of those. We wrote customized
database systems for specific others....trucking, inventory control,
etc. We made more money on support than sales. Computers were not a
do-it-yourselves plug-n-pray like today. We bought terminals for it
directly from a dumb terminal manufacturer 35 miles away in Columbia,
SC. We also sold the terminals as a dealer...ADDS Regent series, mostly
model 25...built like a tank.
Being an OSI dealer was a hobby for our CB business, but became much
more serious as we learned how to be computer dealers with on-the-job
training. 1975 up....great fun! Seeley Communications, Sumter, SC. My
biggest sale was to Liggett and Myers Tobacco Company in NC. We sold
them twenty four C4P with dual floppies and monitors to set up a
computer training class for their employees. Boy did we smile coming
home THAT day driving back to Sumter!
