Its primary architecture dates from the early 1960s. That
was the 60-bit architecture designed by Seymour Cray. But
this model also implements a virtual-mode in which the CPU
operates in 64-bit mode.
The 960 was a machine of mid-1980s manufacture; they were
being sold through the early 1990s.
Tidbit: "The Cyber 960 and all its peripherals took up approximately
1,800 square feet of space and required over 20 tons of air
conditioning to keep cool."

GIT was still running PLATO as recently as 1990, but was
considering migration to NovaNET.
Hi all.
Things are progressing nicely.
The core board is tested and works. I get the monitor prompt
on the VT220 terminal connected to the RS-232 interface.
That means there is also software for it. Go to the updated page
http://home.hetnet.nl/~tshaj/pdpsite/homebrew/startframe.html
Next steps are:
1) adjust monitor software so it runs without the RAM 5565 chip
2) build the I/O ports interface board
3) write the "low-level" in- and output routines
4) write the "stand-alone" pattern SW (the Cylon-eye on the DATA LEDs)
5) the real work: interface with Ersatz-11 (..John?)
The monitor software (e11-6802.zip) already contains some SW
but that has not yet ran; it just assembles without errors ...

I have the manual somewhere that explains this.
I add a patch that makes the console output appear on the VDM-1.
Other choices are teletype, etc.
Unfortunately, I have temporarily misplaced this all.
I have no idea when I will find it.
If anyone else can help, please do so.

Subject: Altair 8K BASIC configuration
While trying to get the 8K BASIC to work with the Altair emulator, I've
figured-out that there must be some way for the user to define, using the
sense switches, which I/O ports could be used for the console.
Does anyone have the manual for 8K BASIC or handwritten notes on the topic?
I need to find the definition of the switches at startup because I'm losing
console input on the emulator when using 8K BASIC.
Thanks.

Finally dug again and found the TECO manuals I talked about a few
weeks ago. Two books:
The bigger one: (1/2" thick or so)
---------------
cover: "decsystem10 TECO"
first page: document number: DEC-10-ETEE-D
"decsystem 10 TECO
TEXT EDITOR AND CORRECTOR PROGRAM
PROGRAMMER'S REFERENCE MANUAL
This manual reflects the software as of version 23
of TECO"
copyright: 1968,69,70,71,72
The smaller one: (1/8" thick or so)
---------------
cover: "decsystem 10 INTRODUCTION TO TECO (TEXT EDITOR AND CORRECTOR)
first page: document number: DEC-10-UTECA-A-D
"This document reflects the software as of version 23
of TECO"
copyright: 1971,72,73,74,75 (third printing, june 1975)
If there's enough interest, and nobody else has already put these
online somewhere, I'll get these scanned to JPG, TIF, or PDF this
weekend.

This would be a mid-80's system I believe.

Anyone have any architectural or performance info for this machine?
I assume it's a memory-to-memory vector machine like the earlier Cybers?

Did you get any disks?
The bus slots are similar to Apple ][ slots. In fact I think
the Concept hard disk controller is really the Apple ][ Corvus
parallel-interface hard disk controller.
You probably want to webulate to
<http://www.spies.com/~aek/pdf/corvus/> where you will find several
scanned manuals including:
ConceptHWRef.pdf - the Concept Hardware Reference
ConceptServiceMan.pdf - the Concept service manual
Somewhere I have a (photocopied) schematic of the 8" floppy disk
controller too. I'll see if I can dig that out and scan it.

You might get away with ordinary ribbon cable, which usually has a
characteristic impedance around 100-120 ohms, for short distances, but the
A cable is really supposed to be 30 twisted pair ribbon cable (one trade
name
is Twist-n-Flat), characteristic impedance 100 ohms. It's wired pin 1 to
pin 1 ... pin 60 to pin 60. The B cable is supposed to be 26-pin flat
shielded cable, with a drain wire, characteristic impedance 130 ohms. It's
also wired pin-to-pin.
The lengths don't matter, as long as they're within the limits: 35 feet for
the A cable and 50 feet for the B cables. How useful it is to have the
daisy-chain cable shorter than the radial cables, I don't know :-)
