Its a Televideo 1603. What's interesting about
this system for one thing
is that it was made by Televideo, whom I thought only made terminals. It
has two 5.25" floppies integrated with a green monochrome monitor on a
swivel armature and a detached keyboard. On the back are two DB-25 serial
ports, a D-type connector RS-422 port, a telephone jack for a mouse (which
I didn't get), and two dipswitch blocks. Inside it has an 8088 and a
6502! I was talking to Doug Coward tonight about it and he suggested that
the 6502 was for the terminal operation, and the 8088 was actually the
main processor. This makes sense, but I was wondering if anyone knew more
about it.
I may have some software for it... but it's not handy right now (stored
away) - drop me a note if you need it (I'd bet that it is an old ms-dos
or cp/m set, but it might have some unique televideo bits to it.
WAITING FOR HARD DISK.....
on the WD controller chip. I think perhaps the RS-422 port is where
you'd hook the hard drive to.
Really? Seems more like a balanced line serial port (I have a dim
recollection that 422 and 423 are the same, and 423 definitely is
balanced rs-232, unless I'm completely off).
