There is also a serially-interfaced variant of the LA180, which has a serial-to-parallel (*NOT* "Centronics" parallel, for others reading this) converter board mounted internally. That's...quite interesting. Why is it parallel internally... Because the primary intended configuration for those printers is with dedicated printer controller boards like the LP11, LPV11, and LS11. Ahhhhh. Interesting design choice, to be honest. I bet it was a bit proprietary though....fast as well. Of course it's proprietary. You ordered a printer from DEC when you ordered your computer from DEC. It was a very different world back then. A lot of people (myself included) insisted on direct-in-the-bus printer controllers when we saw how badly serial printers tanked the system when we connected them to DZ11s. ;) -Dave -- Dave McGuire, AK4HZ New Kensington, PA
