Marvin, the socket labelled ROM1 should have an Epson ROM in it, and as
far as I know it is the O/S ROM. ROM2 socket on mine has Portable
WordStar and is not necessary to run the system as far as I know. In
fact, I just pulled the ROM on mine and the system still came up (BTW,
those ROMs are neat...they have a little plastic bucket that the ROM sits
in that makes it easy to pull them out and re-insert them). My battery
is worn and does not hold a charge anymore, but it will recharge and
operate for a little while (how long I don't know since I never have it
on for more than a few minutes) but as soon as I plug in the power supply
it works fine. Inside the ROM compartment you will notice an "Initial
Reset" button. Have you tried pressing that? There is also a dip switch
inside (SW4)...my settings are as follows:

1:ON
2:ON
3:ON
4:ON
5:OFF
6:ON
7:OFF
8:OFF

There is a smaller compartment on the bottom near that back of the
unit...did you make sure there is a ROM in there? Is it seated correctly?

Hope this helps in some small way.
