Hi

Does anyone have an HMI-200?

I just picked one up cheap for a 64180.

It's lacking the manuals and the software, very long shot but maybe someone
here has copies?

I was able to get it working using the serial port info from the
HMI-200-68000 manual that I believe Al Kossow found and uploaded to
bitsavers.    By default it's DCE and so needs a straight thru DB25 cable.

All day I've been having issues with it hanging randomly.  Usually after
just a minute or two though it did once stay up for about 20 minutes.  Hard
to tell if it's a serial issue or an issue with the HMI itself.

Tony
