CoCo's *are* real... (was: OT: PC Motherboard with a vacuum tube

Anyway I think most CoCo 1-2 terminal emulators use the Break key as a control key. Not very slick, but it worked. What really sucked was the 32 column screen. I never bought one of the many 80 column cards, they were all serial based. Only useful under OS-9.

Who was looking for old VMS for an 11/750??

by jwillis＠arielusa.com

Cool. So you have an 11/750. I'm curious, what did you do about powering it? I heard they require three-phase 240V power. best john -----Original Message----- From: Brian Hechinger Sent: Sat 9/14/2002 1:32 PM To: cctalk(a)classiccmp.org Cc: Subject: Re: Who was looking for old VMS for an 11/750??

Additional components, such as DECnet for OpenVMS VAX, DIGITAL TCP/IP Services, or VAXcluster, require more memory to ensure satisfactory performance. * The MA780 shared memory is not supported. * You cannot install or upgrade to the OpenVMS VAX Version 7.2 operating system on the following VAX computers and system disks: Computers: MicroVAX I, VAXstation I, VAXstation 8000, VAX--11/725, and VAX--11/782 System disks: RK07, RL02, RC25, RD32, RD51, RD52, RD53, RZ22, RZ25, and RZ23L so the answer is, with enough memory, and the right disks, yes you can. however, the reasons for running pre-7.2 are usually nostalgic. i run 7.2 on all my machines, but only because i'm new to VMS and don't need the added confusion of multiple versions. plus there is the fact that i have all my VAXen clustered, so they all need to be about the same version. for nostalgia, i have an 11/750 that has 4.3 BSD on it since that was where i had my first unix account in college. -brian -- "Oh, shut up Buddha." -Jesus Christ (South Park)

HP CS/80 Instruction Set Programmers Manual (5955-3442)

by glenslick＠hotmail.com

I did get a private reply with a temporary pointer to the CS/80 spec so I now have a copy. Thanks to some help from Bob I got past the HP 2117F power supply issue so now the box is not totally dead. Some day after I figure out a lot more about how this system works I'll have to try building an HPIB cable to connect to the 12821A disc interface in the system and see if I can get it to talk to one of my CS/80 drives. Apparently this box has a CS/80 boot prom which I have been told is not too common. -Glen >From: Joe <rigdonj(a)cfl.rr.com> >Reply-To: cctalk(a)classiccmp.org >To: cctalk(a)classiccmp.org >Subject: Re: HP CS/80 Instruction Set Programmers Manual (5955-3442) Date: >Fri, 13 Sep 2002 17:14:48 > >At 11:22 PM 9/12/02 -0700, you wrote: > >Does anyone on the list have a copy of this manual that can be copied or > >scanned, or is there a scanned copy on the net somewhere already? > > > I think Frank McConnell has one.

Deskstation Raptor 3 for sale.

by listor＠melin.org

Available in the Stockholm, Sweden area, I have to get rid of some computers due to the wife-is-getting-sort-of-mad-at-this-computer-collecting-business-problem and this one must go : Deskstation Raptor 3, featuring : Full Tower Case Alpha 21164 UniFlex Motherboard 4 PCI / 3 ISA slots Dual SCSI II ports 2 serial / 1 parallel ports 1.44 Floppy Drive 96MB RAM / 2MB SRAM Cache 1.9GB SCSI II Hard Drive S3 something VGA card (will produce 1024x768 in 16bit color) 10/100 NIC with Digital chipset that works great with NT4 The computer works great. The only thing that needs replacing are two 8cm fans that was mounted in the front panel of the case. They were completely shot and I removed them a while ago. Please email any bids, small or large to joacim at melin dot org. I will ship wherever but please bare in mind that this box runs on 220 volts power and purchaser will pay for all shipping costs and other fees. I don't have any illusions of making a ton of money out of this box but I want it to find a good home and not being dumped somewhere, which is what will happen if I don't find a new owner for it. To sum up - it's a great box. It won't run Linux or any flavor of BSD but it's still a great machine to run as a server. I have tried to boot the Windows 2000 RC1 beta on it but it never get's pass the boot screen... Joacim

Have DG AV530s, need media/docs

by classiccmp＠crash.com

I've recently come into posession of two working Data General AViiON AV530 workstations, and an as-yet un-tested AV410. Copyrights on the PCBs indicate a 1990 provenence so I think I'm okay WRT list rules... ;^) First question: Anybody have bootable media that they could see fit to duplicate or loan? None of the BSDs seem to have made it to the DG m88k boxes, though many people have asked and some work has been done. (Last time I checked was a while ago, though...) Second: Anybody have docs for this model, paper or 'lectronic? Third: The AV530s are dual-capable - can I just pull the CPU from one AV530 and pop it on top of the connector blocks on the other AV530? Wouldn't mind hearing from someone before I discover the answer myself via a smoke test... There are jumpers that are labeled clearly WRT running sinle- or dual-processor, but is there anything else I need to know? Thanks, --Steve. Steve Jones ...!uunet!crash.com!smj Arlington, Mass.

Available - UK- Tricom Custodian II Network Security Controller

by dave＠naffnet.org.uk

Hi, Looking for a home is a Tricom Custodian II network security controller. This is a device that sits between modems and equipment to be protected (host computer/terminal server etc.), and provides a layer of extra security, including ring-back. This is a 19" rack-mounting unit with dual (one redundant) power supplies. The frame itself consists of a backplane that accepts HD63B09 (6809 compatible) SBCs, each controlling two host/modem pails (four serial lines). The frame accepts one Supervisory Module. and up to 16 Line modules (the cards are distinguished only by their firmware). The Supervisory Module has connects to a serial log printer and a terminal. With the frame comes the SM and four LMs, and cables to suit (so up to eight lines could be protected). There is a manual, too, but I have put it in a safe place, so it'll have to follow the unit when it re-surfaces. The system is menu-driven, and is fairly intuitive, so this should not be a problem. I am looking for some sort of swap:- I would love a KA655 CPU for my uVAX, perhaps with some (up to two) 16MB memory cards to suit, or a very basic EIS '11 QBUS system (no need for storage, just CPU/serial/memory). I am, of course, open to other offers... The beast weighs in the region of 12Kg, plus cables, so collection might be the best option (west Berkshire), although I'm sure that Parcel Force would appreciate the business. Cheers, Dave.

Your M20 problems

by dwightk.elvey＠amd.com

Hi Hans It just occurred to me that your system may have the same problem mine did when I first got it. I was seeing occasional bad reads. I took the drives apart to clean the heads when I noticed something funny. Both disk drives had terminators installed. I removed one of these and my problems went away. It was such a long time ago that I'd forgot about it. While tracing down signals for my 512K fix, I noticed the terminator R-Pack that I'd taped to the disk drive ( I try to follow the first rule of intelligent tinkering: "Save All the Pieces" ). I had to go back through the thought process of why it was there. Eventually, I remembered that you were having drive problems. Strange how the mind works sometimes. Dwight

CP/M-8000

by dwightk.elvey＠amd.com

Hi He should also be aware of the manuals at: http://www.spies.com/~aek/pdf/digitalResearch/ and http://www.retrocomputing-world.com/biblio/cpu/z8000/z8000.html Chris and I are working on getting CPM-8000 up and running on our M20's. It has been a slow project. I just yesterday figured out how to get the machines to take 512K of RAM ( CPM8000 needed 128K of free RAM and the normal 224K system was not big enough ). Chris is already quite handy with the assembler but I've mostly been looking at hardware issues with the help of the manuals from Hans Pufal. Progress is being made but it is slow. It takes me several hours to pull the 16K DRAMs to stick in 64K one on the expansion boards. I currently only have one card modified for a total of 256K ( w/ motherboard ). When I do all three, I'll be at 512K ( a power user ).
