Sam,
You know I have a few Spectrums, Spectrum+s, and a Spectrum+3 in my
collection. I showed them to you.

In the S.F.Bay Area, I find the best "finds" at a chain called Thrift Town.
I think it's because they aren't picky about what they accept as donations.

Did anyone else besides Gimix and SWTPC produce SS-50 or SS-30 bus cards?
I'm still looking for a 6800 processor card for my SWTP 6800.

A couple of years ago I bought a NeXT motherboard with a 030 at foothill.
It came in the box for a 040 "Upgrade kit" motherboard.

I have a book called "The NeXT Book", covers hardware and software.
Want to borrow it?
For Trade:
===================================
One very nice book for anyone interested in computer generated music.
"Music by Computer", John Wiley and Sons,1969,139 pages,hardbound,dustcover
edited by Heinz Von Foerster and James W. Beauchamp
This book was started from papers submitted to the "Computers in Music"
session at the 1966 Fall Joint Computer Conference in San Francisco.
Authors are James W. Beauchamp, Herbert Brun, M. David Freedman,
Lejaren Hiller, M.V. Mathews, J.R.Pierce, J.K.Randall, Arthur Roberts,
L.Rosler, Gerald Strang, and Heinz Von Foerster.
In a pocket in the back cover is four 7" floppy records with a total
of 8 sides, containing examples of music and sounds to accompany each
paper. The records are in excellent condition, no scratches.
Example:
"A Computer System for Time-Variant Harmonic Analysis and Synthesis
of Musical Tones" James W. Beauchamp Ph.D., Assistant Professor of
Electrical Engineering, University of Illinois.
The music example is described as:
"Musical Instrument Tones
Synthetic versus Real
Side 8 band 1,2,3
The example consist of a series of comparisons between some musical
tones as they were original recorded in a sound chamber and the
corresponding tones synthesized by digital computer ..........
..... The synthetic tones were produced by
The CSX-1 computer (A/D conversion)
A CDC 1604 (analysis)
An IBM 7094 (tape conversion)
The Illiac II computer (D/A conversion)
Three musical instruments were synthesized: the flute,oboe,and cornet."
===================================
A programming manual.
SAIL August 1976, Stanford Artificial Intelligence Laboratory Memo AIM-289
edited by John F.Reiser. Softcover, plastic "ring" bound, 173 pages
The cover has been separated from the manual but otherwise it's in very
good condition.
"ABSTRACT
Sail is a high level programing language for the PDP-10 computer. It
includes an extended ALGOL 60 compiler and a companion set of execution-
time routines............. This manual describes the Sail language and
the execution-time routines for the typical Sail user: a non-novice
programmer with some knowledge of ALGOL. It lies somewhere between being
a tutorial and a reference manual."
======================================
If anyone cares:
Friday night, the TRS-80 user group I belong to held a belated 20th
birthday party for the TRS-80 Model I which was introduced August 3rd
1977. There was balloons, coffee, and donuts. Our resident guru first
talked about the history. Then he brought out a Model I and went through
the evolution of the Model I. Cassette, modem, expansion interface, disk
drive, and hard drive. At the break, we had a contest playing lunar lander
for the lowest score. The three lowest scores won software.
Finds:
Last weekend at the Livermore flea market I found a ELF II hiding in
a box of junk. So I decided to put togather an ELF exhibit for the
show consisting of the ELF II, an ELF home built from the 1977 PE
construction articles, a Super ELF and the Super ELF in the S-100
Super Expansion Chassis.
A few weeks ago I picked up an Amstrad PPC640 portable computer.
Fold down keyboard,fold up LCD display - the only way I can describe
it is - very sexxy.
Others finds - APF M1000 (video game sys) and about 5 cartridges, a Coleco
Telestar Arcade (triangular cartridge - cool), TI99 external floppy
controller and external drive (never seen one before).
And a DECmate III.
