opening and closing the case every time I want to work with the thing is getting tiresome... but space and the necessity to "batten down the hatches" requires its full assembly when not in use. so mounted a 3.5in drive in place of the original 5.25... took a while to find the right drive for the job... and had to resolder the drive-select jumpers. But it's just a standard 1.44mb drive and works... no other jumper changes required.

Had a brilliant idea to mount the original drive inside so it can't get misplaced... went through all the racket necessary (reopening the case, removing the PCBs, mounting the thing, making sure it was secure for transport...

Friggin thing fit perfectly. Then put the PCBs back in.... and dag nab if it wasn't 1/8th of an inch too high. So the original drive and the kaypro may both be suffering separation anxiety.  I kinda am as well.

Ran some experiments while it was open... tried running the logic analyzer program with the board disconnected. Definitely failed all self tests. 

So looks like the LA board is functioning, despite not having sampled any data yet. Also, it detects that I hadn't yet attached the probe-pods. Smart cookie.

Also experimented with the other programs

D.com (?) has a sector error. And recall that there were a couple failures during the write-process... so may just be a flaky disk.

Stardnld.com (?) just freezes...

But prog.com apparently turns the thing into an eprom programmer (with the right personality modules... which of course I don't have)

Pg.com turns it into a pattern generator... 16 channels?

La.com is the logic analyzer

Pip.com is the cp/m program for peripheral intercommunication (basically xcopy or dd, if I understand)

Masmenu.com makes for a nice UI.

And here's a full listing of all the files... since two folks, now, have been unable to mount successfully with cpmtools...

...

Other notables: "Omni4" is printed on screen in many locations... once before reading any disks, so this must have a custom ROM, rather than the standard Kaypro 2x ROM. Got the eeprommer running with the 486 lappy (man it's way easier to use floppies than my original plan to use xmodem) and waiting for my next patience with case opening, etc. 

Thanks to my new pal ziggurat for bringing the custom ROM and more to my attention.

Also cp/m appears to be customized.

But we're pretty durn certain this is a kaypro 2x.

Also... the 3v battery (over 30 years old) has 2.73v on it... so if anyone knows how to read things in the nvram and/or date/time on one of these things, we're curious what it's been holding onto all these years.
