RE:PANASONIC HHC RL-H1800 TV DISPLAY ADAPTOR

Thankx all for the info and help with my HHC questions.

i did win the ge programmer with working HHC on ebay for around 50 dollars.

so now i have an hhc with working display and some GE spares.

Tony my answers to your post is below:

...
 Waht exactly is the fault with the existing one?
Missing columns? Missing
rows (over part of the display?) Odd dots missing? 
Missing row's on the last third of the display almost to the end of te display. 

...
 The only HHC peripheral I ahve seen is the
printer/cassette interface and
tht contains a ROM and a custom I/O chip. I would be very suprisied if
the display interface was all standard ICs. 
there were a few hhc peripheral's besides the tv adaptor and printer.

according to my manual that came with the hhc used in the ge programmer there was: the I/O
adaptor for six peripheral's, two printer's with cassette i/o on them , an
acoustic coupler modem and a ram module.

Ge used two modules with the hhc/printer/io adaptor setup: one module held eproms for
software that programed the ge two way radios and the other module interfaced the
radio's to the hcc via cable or ZIF sockets for bare eeproms.

google "ge suitcase programmer" for info on the GE/HHC setup.

there was one other HHC set up that used only an HHC and printer for insurance companies -
the printer attached directly to the HHC and the custom insurance software was on a
"capsule" (rom chip) that went in the back of the HHC.
