Hi,
I'm not prepared to lay out $200 for these Xerox ROMs, but if I do manage
to get them, I'll read and share them. I did not know there were 5.0 ROMs
for the 820-II, but it appears there were, and they are included.

I have a Xerox 820. I don't know how to tell if it is a -II or not. It is
marked as U05-013264
September 1984. It powers on and boots the monitor. Looking at the PROMs, they
are labeled:
U33 5.0, U34 5.0, U35 5.0, U36 5.0, U37 4.01, U38 4.01
At some point, I need to ask someone to make me bootab
There are guides online, the differences are documented, I believe you can tell
from the outside. Bezel color is not always a 100% indicator.
Floppies are at least easy for them! If no one else can do it, ping me and I
can run off a set.
Thanks,
Jonathan

It appears that mine is an original 820. I need to look inside to see if it has
the double density
upgrade.
I may take you up on your offer at some point.

You have an 820-II; the original 820 only has two ROMs (U63, U64).

Turns ur 800 in a c64.
Cool
I wonder what would be needed to connect a C64 module. I have an 800 but no
C64. I have a Forth module for the C64 that I'd like to fiddle with.

I wonder what it would take to go the other way. I have plenty of C-64’s and
no 8-bit Atari computers. Maybe I’ll finally get one at the next PRGE.

A lot more, I should think. This is just Commodore BASIC v2.0, which has
just about zero special hardware support and was ported almost verbatim

No, I don't think that is true. What is true is that recent versions of SIMH
will create full size container files f
