A pair of Pets - Preparing to test after perhaps 40 years unused

[daver2]

That is what I am sort of expecting.

So either a ROM or RAM fault in my book.

Looking at my socketed ROMs:

In our Universal Pet (I called it Dynamic before but realise that's wrong!):

UA3: 9013447-10 (39 '83)
UD7: 901474-04 (02 '83)

In my other 8032 (030) that's untouched so far:

UA3: 901447-10 (50 '81)
UA7: Already an EPROM, TMS 2516JL-45 DAP8140 - the window was exposed on this although in my care it's been closed and in the dark for a long time. I put some tape on anyway.

Any use? Or park this until I've got 2716's?

WHile waiting:

(I think) I was able to read the UD7 EPROM from the 8032030 - attached.

I wasn't able to read the same mask ROM from our 8032090.

I've tried using the EPROM in the 090 but it made no difference, still blank screen.
