Subject: QX-10 tech info

Hi!

I have the techinical manual for Epson QX-10.  Nothing on Hard disk,
but I can help with floppies.

YES!!  The US output of the uPD765 is decoded into ALL FOUR drive
select signals, something that doesn't always happen with two-drive
machines (IBM-PC, especially the Jr.).  But, You DO have to modify
the bios - actually, it can be modified by an application software,
and that's the beauty of it.  I think you should talk to Epson and
ask for the BIOS listing as well as info on Extended BIOS.  (BIOS
being NOT the ROM but the CP/M BIOS!!! - that's why it can be modified
with an application...)

Drop me a line directly, and I'll see what I can do to help you.
