ZX81 video mod and bus extention cable

[Glen Goodwin]

Hello Jim --

I have a scan of the video circuit mod for composite
output -- if you want it, contact me offlist and I'll
email it to you.

As far as a bus extention cable, I use old 50-conductor SCSI cables.
For the cable ends, my junk box is full of suitable scraps, but if yours
isn't, you can use the connector from a dead 16KB RAM pack for
one end, and any surplus place should have an appropriate piece
for the opposite end, which can be cut down to size and key-notched.

Later --

Glen
