[GreenKeys] HAL CT2100 ROM checksums?

[Steve]

Hi Guys,
I'm working on a HAL CT-2100 and it appears that the microprocessor
is going nuts (none of the CPU controlled functions do anything, garbage on
the display), so I suspect one or more of the EPROMs are bad. Does anyone
out there have the checksums and/or the images for these? Not the kind of
info that would be in the manual, which I'll need to find eventually.
