Well, I've now acquired a PC05 high-speed paper tape reader/punch for the PDP-11/20 I'm currently restoring. I still lack the PC11 board, though. Megan's list says the following: M781 PC11 U PC11 control board for KA11 M7810 PC11 U Paper tape reader/punch controller Do I *have* to use the M781 version, or can I also use the M7810 if it's all that I can find? What is the actual difference between the two boards? Next: why were the backplane modules mounted at the top of the BA11, wire wrap up, in the 11/20? It's easy to flip the thing over while it's not in a rack, but when it's in a rack... Some trivia: the two partial 11/20's from which this one is being built have serial numbers 786 and 1102. -- Jeffrey S. Sharp jss(a)subatomix.com

I also think it's a good idea. I get pretty fed up with long off-topic threads especially those of a political nature, though I don't mind the occasional off-topic post.

SemiOT: Mourning for Classic Computing

I'll take this even one step further... learning programming isn't learning how to construct applications. They didn't teach how to construct applications when I was in school; and now, with RAD/IDE and class libraries/frameworks, most people never learn. Since constructing applications is (generally) platform-dependent, it might never have been/be appropriate to cover in a college course. Fortunately, my career path put me in the position of maintaining systems constructed (or *not* constructed) by others. I found that I learned how to conceive a large system and implement it by factoring by immersing myself in a previous system that someone else wrote, and while immersing myself, watching out for bad habits to be avoided.

SemiOT: Mourning for Classic Computing

Most likely you're correct, but then I associate BASIC with a full compiler that could generate 132-column headered listings complete with symbol table and assembly language output for each statement. Some 8-bitters *did* boot directly into Pascal... at least I never saw a copy of UCSD Pascal that was anything other than language environment *AND* operating system combined... And as for booting directly into a language environment, any old FORTH programmers here? At one time, I thought FORTH would rule the world.

NOTICE FROM ....... -- NO HTML please! --

by sipke＠wxs.nl

One of the rules that would make sense to me would be that people would stick to plain text mail, rather than fancy large letters etc. NO HTML PLEASE (so of us can't even read it !) As an example I've recoded the offending posting .....

Exidy Sorcerr - IT WORKS

Thanks for the acknowledgement, but I have to say that it was Louis's own perseverance and hard work that got the machine going :-) No mean feat, considering he didn't know much about logic circuits before he started, and this machine actually had several faults! -- Pete Peter Turnbull Network Manager University of York

I checked the pinouts -- the EPROMs do need to be TMS2532.
