Atari computers had a region lock?

I'n not sure, actually, I've had more experience with IBM PC's than Ataris

I would assume different versions of the ROM for running different software, possibly one with performance hacks.

It looks like two EPROMS piggybacked, with what I can only assume to be two different BIOSs, mounted in a socket, op top of the stock BIOS chip

Hmm, I guess I'll have to boot it up and find out

Probably some BASIC extension.
Also, it's not BIOS it's ROM.
Power on and show us!

You may be right. I hooked it up and got a command prompt with an "OMNIVIEW XE" placard up at the top.
Surprisingly, my 4K tv can display the composite signal without the sync hooked up. The screen rolls, but I figured that was quite impressive

Pics!

These shots are RF -> VCR -> Composite

Yeah, you get a different prompt when toggling the switches and restarting?

>>57386963
Yep, but the omniview doesn't allow regular characters. That garbled mess is what you get from pressing a couple of keys. The pattern differs depending on the key. Pressing it once seems to open up a query, and pressing it again sets a column.
I just got to some strange self-test menu just now, pics to come

Turns out the self test is a feature, not modded in.
