CMT MC-II 8088 CMOS System

[Bill (Smithville NJ)]

I was at an hamfest this morning and picked up a CMT MC-II 8088 CMOS System manufactured by Corvallis Microtechnology. It's a handheld device that has the following modules:

four 128KB SRAM
MC-ROS
MC-41M

I put five AA batteries in it and it does power up. But now I am at a loss. When it first powered up, I had a menu of items. I then ran the 41M module and that seems to be an emulation of the HP-41 calculator. Not sure now how to get back to the main menu.

It only came with a hard leather case - no manuals. It looks like it would support keyboard overlays that would probably be a big help in using it.
The top of the unit has two RJ-45 jacks. On the back is a covered connector.

I just pulled the batteries and reinserted them and am now back as a list of items. There are a bunch of ".S" filenames (41M.S, OFF.S,KEYBEEP.S, TIME.S, DATE.S, MODE.S, etc), then KERMIT.X, MCED.X, CMD.X, CMT-ROSS.

Then it says Bytes Free - 16016. Which seems odd, since there are supposedly four 128KB modules installed.

Does anyone have any information - manuals, overlays etc.

Thanks,
