I have a LCA-1 and it doesn't seem to be working. I loaded up AppleWriter II and my lowercase is just some random pixels. I do not have the Manual any longer and do not know what needs to be done to get the thing to work. Any one with knowledge is appreciated.
There is some info on the Dan Paymar LCA in this zip file on asimov: (it probably should be better named)

I'm not familiar with how the board works, but I assume there's a character ROM on it? Do the random pixels change depending on which key you press? Do you always get the same pixels for a specific key?
What is the revision of the motherboard ?
IIRC, LCA-1 was designed for the earlier (pre Rev 7) motherboard using 2513 EPROM.
