The seasonal holidays give me time to play around a bit ...
I wanted to connect my DECprinter I (that's an LA180) but
I could not find any documentation here at home, neither
on the web! Can somebody who knows or has an LA180
connected tell me how it is hooked to a serial line?
It's not!. The interface is a TTL-level parallel one, somewhat similar to
Centronics, but IIRC some of the control lines are inverted, etc.
IIRC, it connects to an LP11 or LPV11 card. The cable is straight-through
wired, I think, but you probalby flip one of the connectors over, as is
usual with DEC cabling.
Or point me to an LA180 user's manual on the web?

I suspect applying RS232 levesl to the connector will cook a few ICs. I
do have the printset somewhere, so it would be repairable...

From my guess, the BERG header is
"standard" as on M7800
DL11's or M7856 DL11-W, SLU's (with the
appropriate lugs
either RS-232 or 20 mA current loop), but I would rather be
assured than destroying a very nice printer!
