Anyone have an Ethernet interface card for an AT&T 730 terminal?

[Al Kossow]

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.
