Televideo TS-806/20 - test-drb@ccmp.vtda.org

11 Jun 1999

Well, I'm not sure I agree about the relative importance of cables with
which to interface a hard disk.  That's probably the one thing that makes a
computer compute fast enough to be useful.

First of all I'd try 9600 baud before anything else, since I believe that's
the default.  I don't remember what the board switches do, but I can hunt
around for the manual and get back to you.  I wouldn't use PCAW, as a
terminal, myself.  I haven't had good luck with it.  How about Hyperterminal
of Procomm.  I've used both of those in connection with a PC and had better
luck than with PCAW, though I've had good luck using PCAW for file
transfers, etc.

This box was ostensibly a file server and probably contains VERY important
software, e.g. the MMMost (or whatever it was called) network OS, which
isn't around any longer.  This box is capable of serving as a single-user
system, but if you still have the HDD, from which it should boot all by
itself if it hasn't been roached up, you might want to preserve it.

Well you're in luck . . . I got a phone interruption after which I thought
of a place to look for the manual...Oddly enough, that's where it was.

The manual says the  "upper" four bits of the dip switch is used for baud
rate settings.  The lower four bits (5,6,7,8) are unused except for position
8 which is reserved for diagnostics.  Obviously, the one who wrote this
manual was on drugs.  A closed switch is a zero.

The baud rates go from 19.2K down to 75, with ascending values from 0000 to
1000, remembering that a 0 means CLOSED.  Switch 1 is the lsb.

I hope that helps you get it going!

If you need a boot diskette, maybe I can help you there as well.

Televideo, by the way, is still in business, so it's not inconceivable they
might be able to help too, if you ask them.

 I don't have the cables for the winch (control) or
winch (data) ports
although I have a board for them...they aren't important, I just thought
I'd mention that.  I don't have a (working) terminal right now, so I tried
it with my pc (via serial port & pcAnywhere emulation of TVI 925 @ 75 to
1200 baud settings, n&e&o parity, 4 - 8 data, and 1 stop).  With any of the
settings, I get garbage on the screen.  I would like to get it to work with
my pc.  Any help in those settings in particular would be great.  I noticed
8 dip switches on the main board.  Do you know what they are for?
