Curricula (was: Assembly vs. Everything Else

by ken＠seefried.com

Jumping in late, I know, but when I was at Georgia Tech (mid- to late-80s), we were taught x86 assembly. There was a real focus on the concept that "look folks, there's an awful lot going on under the hood that you might want to be aware of when you write that Pascal (or C, or Lisp, or whatever) program and the details matter". For that lesson, x86 asm is a pretty good, if painful, object lesson. Much of GaTech was like that. Oh, yeah...and we learned Modula-2 from Kim Kings book for undergrad OS. Ken

symphony for dot matrix printers

by acme_ent＠bellsouth.net

This is fantastic -- thanks for sharing. Being a musician, this conjures up all sorts of ideas for using computer sounds to make music. I have a recording studio hung off my main non-classic box, so I can add this to my List of Unfinished Projects. Some useable sounds might be: (printers, of course) hard drive spinup & chatter crt charge & discharge floppy drive stepper motors ps fans cpu cooling fans cd drives (opening, closing, and spinning) scanner sounds tape drives ASR 33s PAC readers card readers So what did I miss (classic or non)?

Nabu Computers Available...

by hardwire＠ptd.net

This might be of interest to somebody here (hopefully)... Surplus Traders (www.73.com) currently has 35 Nabu computers for $29.00 a pop, plus shipping. Normally they do bulk sales, but they will sell the Nabu individually. (Search for item CR356.) I picked one up a while ago, and mine was still 'new', in the box, with a factory seal. Then again, since this surplus, it might be best to verify that the units are 'new' if that's important to you. Unfortunately, I haven't really toyed with the Nabu hardware too much (yet), and if anyone else has, I'd love to hear about it. Either way, these machines are certainly an interesting part of computing history. Here's a small blurb about the Nabu: http://ieee.ca/millennium/telidon/telidon_nabu.html

PDP 11/34 work party

by KenzieM＠sympatico.ca

Well this is the weekend that I'll try and get the PDP 11/34 running as well as the AS400's in the garage. Anyone who will be in the Ottawa area is welcome to come and help. I'd like to see some signs of life before packing the magnetic media into the basement for the winter. Mike Collector of Vintage Computers (www.ncf.ca/~ba600)

DEC rack header plates

by mrbill＠mrbill.net

Anybody know a source of DEC rack header panels (the maroon/red ones) with or without logo, or for the black "cover panels"? I've got a maroon/red pdp11 header panel, and a "blank" maroon/red one, but not the black panels to cover the rest of the cabinet.. Bill -- Bill Bradford mrbill(a)mrbill.net Austin, TX
