An Open House at RCS/RI <www.osfn.org/rcs>...
We will be getting rid of quite a few things, including a number of
untested RL02s (drives, not packs). Obviously, these are pick up only.
Come on over!

Subject: this weekend
Our Open House is Saturday, June 16th from 10am - 4:30pm
The topic is Games! and we will be featuring SpaceWar on the PDP-12
and other games.
On another note, we need some bodies to help move some things around on
Friday afternoon. I'll be here from about noon on, and Dave will be
stoping by after work. But we need at least two more people. RSVP if
you can help.
The goal is to move the Wang VS100 and peripherals out into the
hallway, in preperation for RICM to pick them up on Saturday. Dave and
I have already moved the printer, disk and tape drives to the edge of
the aisle, but getting them to the door will require moving several
other machines. Please help!!

I have a Toshiba T1000 portable personal computer that I would like to offer
up for trade or sale. It has built in MS-DOS 2.11, 640KB RAM, 8088
processor, 3.5" 720K floppy, 640 x200 LCD, CGA external drive, internal
modem, parallel port, serial port, original user manual and carrying case.
It's in good shape and functional. If this would fit into your collection,
please contact me directly at:

thanks Norm
I'm forwarding this in case anyone on this list is
interested in these manuals.

Hi all...
I've been trying to get some action from this IMSAI for awhile now. Main
problem is I don't know what is on the EPROMs on the EconoROM board. It
looks like banks A & B, OR banks C & D, can be enabled together starting at
address 0000h. There are 6 2708's in A0 through B1, and 8 2708's in C0
through C3.
I've been looking for an EPROM burner that can read/write 2708's with no
luck so far. We have TWO machines at work, and neither will do it. Anyone
know of a burner that WILL?
I manually read the first 256 bytes of the first chip, and disassembled it,
also manually - I'm looking for a good disassembler program too! I've got
one called DASM V1.2 by John Wilson, but have been having some trouble with
it.
If you've got a few minutes, have a look at what I've included below - the
first 128 bytes of code. Let me know if any of it looks familiar. (Or if I
messed up the job!) The comments are for my own benefit - I'm pretty rusty
with assembler.

Joe,
Better stay out of the sun. I think you fried to many neurons. Mike ??? has
the EXOR-bus stuff :-)

Hello all,
As promised, here is the list of EXORbus cards that I have... Any docs or
information on these would be greatly appreciated! (Thanks to Mike and Joe
for already replying to my previous post)...
1 MEX68WW Wire-Wrap prototyping Board (uh, well, I guess this one is
self-explanatory :-) )
1 CMS 9601-501 "Utility Buffer/Cable Breakout" Board (2 ports)
1 CMS 9601-503 "Cable Breakout" Board (8 ports)
2 Chrislin Industries memory board -- 32 4116 chips
2 Motorola Micro Module 1A (one has 4 2708 EPROM's, labels all faded)
2 CMS 9650 Serial I/O Board (8 8650 chips)
2 card extenders w/ test points
1 Micro-Logus P-VDG board (CRT-5037 and CRT 8002 chips, also 4 2016's, and 4
output jacks, coaxial, but smaller than say a cable TV coaxial cable. Also
output jacks are NON-threaded.
1 CMS 9609 MPU board (6809, 2 6821's, 2 6850's, 3 2716 EPROM's, one marked
"Debug 09", others unlabeled)
1 CMS 9609 MPU board (same setup as above, but 3 2716's marked "M9M17 #1,
#2, and #3")
1 Southern Company Services SCSEVDG183, very similar to P-VDG board above,
but w/ CRT-5027, and 4016's instead of 2016's)
1 Hodge Taylor and Associates P/N 040478 (all 74XX logic, no ideas as to
function)
1 Hodge Taylor and Associates P/N 033178 (again, all logic...)
1 unknown vendor, marked "Interface Board" (2 6820's, 2708 EPROM, marked
"D800" (very faded), 40-pin and 50-pin connectors on top)
1 General Micro Systems "Versatile Memory Module" (16 sockets, 9 filled w/
2716 EPROM's, marked "IRCS 0.64" -- Also has battery backup!)
1 CMS 9640 Timer Board
1 Hodge Taylor and Associates P/N 12877 (2 AM2901BDC, 3 AM2909PC, 4
N82S2708N)
Thanks in advance!

operands 20-nsec cycle time Scalar Unit Segmented functional units 64-word
instruction stack 256 word high-speed register file Vector Unit 1, 2, or 4
segmented vector pipelines memory-to-memory data streaming maximum vector
length of 65,536 words gather/scatter instructions up to 800 million 32-bit
floating-point operations/second
Interconnect / Communications System
Memory System
Memory
MOS semiconductor memory
Memory size: 1, 2, 4, 8 or 16 million 64-bit words
Virtual memory accessing mechanism with multiple, concurrently
usable page sizes
SECDED on each 32-bit half word
48-bit address (address space of 4 trillion words per user)
80 nsec memory bank cycle time
Memory bandwidth: 25.6 or 51.2 Gigabits/second
Benchmarks / Compute and data transfer performance
Performance:
Linked triad performance on long vectors approaches asymptotic
speed of machine.
Performance can be severely degraded at short vector lengths
(that is, the typical $n _ {1/2}$ is around 100), and if
vector is not held contiguously. For this reason most
tuned software employs long, contiguously held vectors.
Operating System Software and Environment
Software:
Virtual operating system
Batch and interactive access
FORTRAN compiler
ANSI 77 with vector extensions
32-bit half-precision data type
Special calls to machine instructions
Automatic vectorization
Scalar optimization utilizing large register file
Utilities
Interactive symbolic debugger
Source code maintenance
Object code maintenance
Networkability/ I/O System / Integrability / Reliability / Scalability
I/O
Eight I/O ports, 32-bits in width, expandable to 16
200 Mbits/second for each port
Maximum I/O port bandwidth of 3200 Mbits/sec
Miscellaneous
Cooling: freon
Dimensions: floor area (four pipe model) 23 ft x 19 ft
footprint (with I/O system) 105 sq ft

I've been selling some analog and digital test equipment, some synth
and music-related stuff, and some computer stuff. NeXT Dimension
boards, for example...I had about a dozen of them, and most of them
went for around $400/ea. It's been profitable enough to pay my
$1400/mo rent and my $700/mo car payment, as well as other bills...no
"think" to it, if I hadn't been doing this, I'd be bankrupt...or
worse, working a 9-5 schedule, being taken advantage of by suits and
having clueless MCSEs trying to take credit for my work.
I'm not bitter..
