Mylar LT cable was No one likes Otronas?

Not quite the same thing, but I was looking at the signals going to the display in the HP110 and 110+ last night. These machines have dot-addressable monochrome displays. There are 11 wires : 3 power : Groumd. +5V, -8 to -13V (depending on the contrast setting) 4 clocks : a) What looks like a dot clock or data strobe b) Possibly start-of-line sync c) Possibly start-of-frame sync d) What looked to be an LCD backplane drive clock 4 data lines. No idea (yet) on what the data means, but these pins did not have regular clock-like waveforms on them. Probably not trivial to drive. HP used a custom chip in the 110 (with an 8K*k SRAM alongside it) and a different custom _hybrid_ in the 110+ (a similar custom chip and 2 8K*8 SRAMs in the same package). -tony
