CMT MC-II 8088 CMOS System - Bill (Smithville NJ) - 05-06-2018 06:49 PM
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,
Bill

Hello Bill,
This device is using a modified version of MS-DOS for its OS.

Hello Sylvain,
I have downloaded the zip file. Thank you very much. This is a big help on understanding this very interesting computer.
From a quick read of the manual, the 41M module creates a super HP-41CX - very large memory storage, register access, and many other added commands.
Hopefully some here will have a copy of the 41M manual.
Thanks again for the files.

LOL, I will put back the file and the link tonight (GMT-4h).
