Hello! Reminds me of how in our Apple days, my brother participated in a course for computers in school. Naturally the others needed to wait until after school, or worse the next day to do their homework. Jay did his on ours. And had our new Epson MX100 printer print-out a fancy banner for it. That printer worked its way past several systems. And according to Epson they stopped making print heads for it, (alone) before someone stopped making ribbons. I think they still make dot matrix ones for those applications that only a printer like that would do. Which includes financials and real estate and possible insurance. ----- Gregg C Levine gregg.drwho8 at gmail.com "This signature fought the Time Wars, time and again."

We all know that. But the LP11 is not really much better. It's also interrupt per character unless I remember wrong. But it's only one printer per card, and no input. And of course, much faster, since it's parallel with handshaking. The Unibus controller I used at work, and later at home, with an LA180 was an LS11. I don't remember if it was interrupt-per-character as well, but since it was fairly non-dense TTL logic, I'd assume it was. It fared very well on my 11/34 running (at the time) RSX. In the mid-1980s, I was the first person to turn in high-school homework on printer paper. Even some of the teachers were asking what kind of "typewriter" made such "strange-looking print". ;) You've reminded me of how I was the only person a teacher knew who did a science project narrated by Microsoft Sam. -Dave -- Cory Smelosky http://gewt.net Personal stuff http://gimme-sympathy.org Projects
