[sebhc] ET/ETA-3400 ROM-Dump Help

[Peter Hofmann]

Paul,

All correct and thats really fine. Maybe that I mixed up the part-numbers,
sorry in latin it means "errare humanum est" ... Paul according to your(!)
spare time, I will be very surprised when you can support me with the
contents of these ROMs. The easiest way will be to read them out with an
eprom burner, but high ATTENTION in the right selection of the eprom-type
(2316)is necessary. The other way can be as I described it in my former
postings in using the built-in monitor together with a teminal-emulation on
the pc. Fine and great ...

All the best from Austria
