Homebrew PCBs

I'll try with eagle later, just tried winline and no response.

To recap, I made a 3 wire cable, and the PC is sending, I checked this
with a dongle with LED's that monitor the lines, I can 'see' data, one
thing that was odd is thatthe calcomp requires 2-2 and 3-3, not 2-3
and 3-2

I tried it with 6-8-20 connected, and without.

In all the times I sent data to it, it never sent anything back, the
LED never flashed, just stays green, the PC side led is gren, but
flashes red/green with data

It has a switch for ccgl / cpgl, it wont like hpgl so I believe after
hours (an whole evening) of google-ing

Dips switches are used for baud/parity etc so I know thats right, its
printed on the back of the printer!

I did once get a built in test print out of it, but cant remember how,
it was not connected to a pc at the time, just power.

I cant call it dead until I have sent it data I /know/ to be good, but
its looking that way, as though its com's side is 'down' but
mechanically its fine and performs a selftest when switched on, moving
the pen to top/bottom corners etc.
