I just finished taking pictures and dumping the firmware from a 730X terminal
but it turns out it has a Starlan and not an Ethernet interface. It would be
nice to get a firmware dump from an Ethernet card. A start of a 630 driver is
in MAME.

It also appears the keyboards for the 630 and 730 aren't backwards compatible
with the other 6xx products and the 5620. 5620 keyboards need -12v which the 630 or 730
don't supply, and the 610 keyboard doesn't appear to work either. Josh took a
couple
of pictures of his 630 keyboard and even though they look similar, the earlier keyboards
were made by Teletype and the 630 is made by Keytronic.

Mine has a Starlan 10 adapter in it, which is apparently close enough to
twisted-pair Ethernet that it can be bridged with one of AT&T's Starlan
hubs, which is how I have it wired to my network. I'll see if I can dump
the ROMs, but they're not socketed so it'll take a bit of surgery. I also
have the ISDN adapter, which has socketed EPROMs.

Also my 730X cart is newer -- it's the 730+ X Cartridge, Issue 1.2 (c)
1991. I'll get those dumped too, hopefully this weekend.
