anyone ever use a USB/Serial cable to connect to an

trying to connect my 680b to my windows 7 computer via hyper-terminal
to no avail. Any special settings I should be aware for terminal
settings (currently using 9600, 8 data bits, 1 stop bits, NONE for
parity and flow control).
Also, anyone know where I can get the ROM files for a 680b?
What you have to set
the terminal to depends on the jumper settings on
the board. It also depends on the monitor itself - there is an ACIA
version which can work with 9600 8n1, but there is also a Baudot TTY
version.
There is a listing of the monitor and VTL-2 at
http://www.altair680kit.com/manuals/Altair_680-System_Monitor_Manual-03-Bet…
(toplevel page http://www.altair680kit.com/manuals.html).
Since the monitor is only 512bytes, it is IMHO not too tedious to key in
the hex codes. The problem is the availability of 1702 PROMs and a
suitable programmer nowadays.
