Barry,
I assume you obviously have added a cell battery to preserve the code in the static ram?
I actually don't own a Romox , curious what the board looks like.
Shoot a few pictures if you get a moment. (both sides)
If you compress them you can upload them here or pm me and I'll give you an email address.

How do you load the Sram

No battery, I've not spent much time with it/them. I loaded the contents via the HRD menu program. (I think)

I'll make a picture or two when I find one. It should be very easy to duplicate.

Yes, when you can. I would appreciate seeing it.
Check your archives ...on what you used with it.
I'll check and see if I can find any info on it.

Thanks.

BTW I uploaded a file detailing how the TI cartridges are setup, especially the TI Invaders board.
