Ah, okay, I found it now. I think I missed the folder it was in when I
originally went looking.

It's very much appreciated - I don't have the experience with this sort of
thing to be able to figure it out on my own where there are vague things that
someone with experience would 'just know' which chip was right and which was
wrong, etc. I'm a pretty adventurous person normally and I've learned a wide
range of skills over the years. I usually try to tackle anything myself first,
and I've rarely had to completely give up and throw in the towel on projects of
all sorts.
I think I actually had a bit of a mental block when it came to the idea of
building something like this because I'd had some headache-inducing experiences
when I was a kid trying to build some simple circuits using 555 timers that
kept going up in smoke because I was too young to think about things like how
much current this chip might actually be able to pass :)... then later had an
EGA card for my PC which I'd got from a friend who worked for a local company
which built them. I only had a monochrome monitor at the time and he told me
it would work with it, it just needed 'a simple modification', which turned out
to be a daughterboard (which I tried making myself with an etching kit) with a
PAL or something on it which needed to be programmed. For the guys at this
company, that was 'simple' and no doubt when you have easy access to the
equipment to burn PALs or EEPROMs it's as simple as it would be for me to see
some part of my kids' swing set fracturing and think 'I'll just weld that up,
it's a simple fix'. That whole thing with the EGA monochrome daughterboard
kind of put me off building anything involving ICs or PCBs and I guess it's an
experience it's taken the rest of my life (until this week) to get over. (I
hope!)

I actually found the zip file you're referring to with the ROM images back when
I first started playing around with REX in VirtualT. That's how I fell in love
with it and first started trying to order one and/or find out more about
getting some for my physical machines...

If there is one available from DigiKey that will do the job, that would be
fantastic news. I haven't ordered the parts I need from DigiKey yet because I
was guessing at some of the ones for QUAD (there are a lot of different
subtypes of many of these parts and I don't have enough knowledge to judge
which ones are suitable equivalents and which ones aren't - I might need to ask
Stephen for some clarification but I need a breather first after that shipping
BS). If there was some equivalent flash chip I could get from DigiKey instead
of Verical that would absolutely make my day.
