> It uses a DP8473AV as the floppy drive controller IC. http://www.osdever.net/cottontail/#Floppy has the data sheet and a app note for the data separator, which is more sophisticated than the one normally found in a 765. I assume there's a way to deterimine if you have a 8473 in software.

Heathkit Manuals Site

by marvin＠rain.org

I just saw a reference to http://www.pestingers.net/pdfs/ on the Heathkit Listserver. It looks like it has a number of other computer manuals besides Heathkit. I've bookmarked it now :).

When I find something incredibly useful I download the content because you never know when it will go away. Like just now the link above shows "service unavailable". Did you Download the content?

how to connect a Kennedy 9100 ?

by henk.gooijen＠oce.com

I downloaded the TC11 and TC-131 manuals. TC11 has two 40-pin connectors, so you can not hook a Kennedy 9100 to the TC11. The TC-131 looks promising ... Question: who actually has a Kennedy 9100 connected to a UNIBUS machine, and (of course) which interface do you use ? It looks like I'm in the market for a Kennedy 9100 UNIBUS interface [preferably a singe board module] :-) thanks, - Henk. > -----Original Message----- > From: cctalk-bounces at classiccmp.org > [mailto:cctalk-bounces at classiccmp.org] On Behalf Of Al Kossow > Sent: zaterdag 25 maart 2006 17:59 > To: classiccmp at classiccmp.org > Subject: Re: how to connect a Kennedy 9100 ? > > > > What interface should I be looking for to hook it to the UNIBUS ? > > Some variation of an unformatted tape drive interface.

Mercury use (WAS RE: hospital surplus)

by compoobah＠valleyimplants.com

Not much use I can think of in computing, but in other things quite useful. Most obvious is gold prospecting, also used in other metalwork (tempering bath), and in a hobby that will not be named to remove lead that is stuck to steel. Also vacuum pumps for home particle accelerators.

4DDN

by compoobah＠valleyimplants.com

4DDN is on its own CD (AFAIK, never used it but it's not on the standard distro), but keep in mind that it is a nodelocked product, which creates issues.

Defunct companies and nodelocked software (Was RE: 4DDN)

by compoobah＠valleyimplants.com

>And I'm curious - how are these issues handled today? I ask remembering >that I once node-locked the software I sold on the SGI. What are the >repercussions for legacy hobbyists, when companies like SGI take a dive? In that case, you either crack the license system or binary-patch around it. If you still have the keys you used to create nodelocked licenses, you can make a "any" license. Further on the SGI note- is there any move to unofficially mirror official SGI stuff, especially TechPubs and patches "just in case"? Perhaps divide it up among several CCmp'ers.

ComputerVision Model 32 system

by compoobah＠valleyimplants.com

Gave it the dust-off and vis inspection - Base is a Sun 3/160 system, Sun backplane, 3004 processor and memory cards. it has a non-VLSI CV SCSI/2xTTY card. The VME terminator cards are CV-proprietary, and are switchable between "VME" and "CV" mode, not sure what the difference is yet. The case is CV-specific, all drives are front-mounted along with the power supply. Old-IBM type superstrong reinforced-plastic skins. The "heart" of the CADDS system is the CV-GPU, two cards connected by 3 ribbon cables. One is a Multibus "interface card", the other is the VME processing part, with 7x AMD 2901 bitslice processors. According to docs, the "GPU" system can be anywhere in the network displaying on a remote terminal if desired, which differs from SGI-type systems. Not sure exactly what is done in the GPU yet. The framebuffer is a seperate VME card, with a unusual DB-25 connector to the monitor that I haven't traced yet. There is also a bridged Multibus tablet interface card. I have docs, but they don't go very deep into hardware. Unfortunately, it looks like it uses a dongle for protection, which I don't have. Good news is that it shouldn't be too hard to workaround, given that it is a ca 1988 machine. It came with full ComputerVision "4.2 UNIX release 4" tapes, SunOS 3.2 and 3.4 upgrade, SunWrite/SunPaint, CADDS, and some other stuff. Gave me a smoke signal on the p/s test, from a cap on the VME terminator board. Everything else looks O.K., except for a broken termpwr wire in the SCSI card.

ADIC 530/H QIC drive

by cclist＠sydex.com

Does anyone on this list have any experience with an Adic 530/H drive? Does anyone have details? (e.g. Capacity, QIC02 or QIC36, etc.) The web seems to have nothing other than folks offering to sell (probably non-existent) units. Many thanks. Chuck

I'll be there on May 13th though. What part of CT? I just hate driving, but Harford is closer by car to me than infoAge, and a more pleasant drive. Kelly
