All,
Looks like we will be able to save these from the Evil Melter,
enough people have expressed their interest. Some points of
interest:
- they are in Santa Clara, CA, not The Netherlands ;-)
(sorry, my German and Spanish friends)
- they are in a "take em all or go away" deal; this scrapper is
not one of the friendliest in the trade... still, he *does* let
me go through things, which he never allowed before...
- i currently dont have time to work on the systems, as I am about
to go to boston, so will just get them and store them in a safe
place until march, when i am back here.
So.. to all who wanted some of the gear: I am going to arrange for
pickup of the stuff (all of the 7 racks, including the ones with all
the lab peripheral shtuff) and take out the cruft. Someone local
wants to pick up the programmable power supplies saturday, so that
is good ("one rack down, 6 to go!") and the digital voltmeter is
also "taken". I will try to compress the stuff into 2 or three of
the racks (the H960 clones from Tek) to save space.
I *assume* nobody wants the Tek displays/terminals.
Nobody wanted the VAX 7000, so I'll try to take some pictures of it,
before it visits the Evil Melter.
Cheers,
Fred
I'm in need of two scsi cables, the ones with the 50 pin centronics
connectors on both ends. One cable needs to be about 5 foot, the other cable
needs to be about 1.5 feet. A 50 pin centronics terminator is needed too.
Also looking for an AGP card that has a fairly mainstream chipset (so X11
will support it) that does 1024x768 in 32K colors. Nothing fancy.
This stuff is only vaguely classic computer related in that I'm trying to
finish off building a PC (AMD K6-2/450!) used to support my classic machines
(for burning tapes, disks, etc.).
Thanks!

Could be. The first EPROM "lives" at 0000H so mine contains:
0000 3E 00 LD A, 0
0002 D3 23 OUT (23H), A ; dunno what this port does
0004 3E 01 LD A, 1
0006 D3 22 OUT (22H), A ; nor this one
0008 21 16 00 LD HL, 16H ; 22
000B 11 00 24 LD DE, 2400H ; 9216 or start of non-SCC memory
000E 01 07 00 LD BC, 7
0011 ED B0 LDIR ; copy 7 bytes from 0016-001C to
2400
0013 C3 00 24 JP 2400H ; and execute there
0016 3E 80 LD A, 80H ; set top bit
0018 D3 2A OUT (2AH), A ; don't even know this one
001A C3 00 C0 JP 0C000H ; start of RDOS?

I have ten Apple IIe's, a Corvus full of MECC and other software. I have a 4 drawer file cabinet full of Apple eucational software, and *lots* of extra Omninet Apple transporter cards, cables, and trunk adapters.
Everythings works just fine.
But..... I have no documentation for the Corvus hardware or software.
The hardware specs are:
Corvus model 74MB7 Rev C SN 398-GN9230-P
The Apple cards "Corvus Systems Transporter 8010-10969 rev E"
The adapters "Corvus Systems trunk adapters A 8010-12393 01"
The cables are marked "OCS II TU 6010-078681-01 low voltage computer cable"
The software is "Corvus Systems Constellation III V3.0"
I need *both* the software and the hardware docs. Of course, I would certainly be glad to find either one!
Any help locating these manuals, as well as any helpful hints, would be much appreciated.
Many tks!!

MS11-xx is alway semiconductor memory of different capacities and speed as
specified by the last two caracters (to the best of my knowledge...)
MM11-xx are the true core memories with the ferrite cores.
(Wanna see a MM11-YP, 32k x 18 core-stack? Then bump the cofee-machine)
several years after Mos memory became available people were still talking
about core if they just meant the mainstorage or R/W-Memory, regardless of
the technology it was built with.

Heh heh, on what frequency is it radiating?
Do you remember the little proggys that would make a pdp produce sound on
an AM-receiver not tuned to any station?

if it is 128kx18, then it is a MS11-LD, and has an integrated parity
controller. I should have the maintenancemanual somwhere if it of use to
anyone. I will sent a free copy to aomeone who likes to convert it to .pdf
file to be put on-line. (Will have to dig it from the garage, however)

Hi, Joe,
(CC to Classiccmp)
You lucked out. Data I/O says that what you have there is the 8MB board.
Enjoy!

"If Salvador Dali had owned a computer, would it have been equipped with surreal ports?"
the museum was just given a nice IBM PC that is a luggable... sort of like a compact!
have not seen many of these... are they scarce? would like to find any advertising material or manuals etc that would complement it in the IBM display... had not really planned on having each and every model on display but this is kinda cute... let us know if you have any related or scans of related stuff!
