Nope , the numerical pad is the rightmost keys,
Itdoes have color keys on the function line. They are
Off Line
5 F-keys
Erase
3 color keys
Reset
Break
The Sound board ( interesting because the main chip was labelled "Sound", with
only a couple of other numbers ) has one resistor setting free like the guy had
some problems and was trying to correct it . there's some burn where it and the
next resister were connected
I guess I'll follow Tony's test procedures to see if I can get it going, but
if there is someone on the list who desires one, I will include the fdd H57
I found 3 weeks ago which I'm sure, based on Rax"s Theorum , was what attracted
it to me in the first place. Rax's theorum mentions nothing about space for
storage !.
Hate Rax, Hate Rax's Theorum. Hare Computers, Hate Land lords !!
Hate inflatable rubber sex dolls with an attitude.
