2013-09-30 Connected to a terminal
This has the appearance of a PC, including pc power supply, slots, etc
on a conventional pc-like motherboard and case.
Some pics: http://www.wormfood.net/old_computers/
Note: bios 0 works with the terminal. When first started, press Enter
to get the logo. Enter HE to get a list of commands. Terminate
numeric entries with a Space (not Enter!).
