Hi,

I am still trying to get the PC-Handyboard connection to work.  I got as
far as downloading the pcode_hb.s19 file successfully.  After I turn the
main board power off and back on (reset), I should get a message on the
LCD screen ("Interactive-C v 2.81 9/28/93...") but instead the LCD screen
just stays lit on, without displaying any messages.


Your LCD is bad. Either the logic to it is in error (check for
an open on the E pin) or the LCD itself is non-functional.
If IC cannot talk to the LCD it won't run.
