[sebhc] H17 ROMS

[Jack Rubin]

The H17 ROM is a 2316 ROM; I haven't checked pin-outs carefully, but I
_think_ it can be duplicated with a 2716. My prom programmer (Data I/O
System 19) doesn't want to read the 2316, but it can burn a 2716. If
nobody responds sooner, I'll verify the compatability (or not) with the
2316 and try to burn a copy from my memory dump (which is what's posted
to the archive).
