Not SCSI. Maybe some later ones were SCSI, > though Tony is right. SCSI is for a Sun connection. VAX is different. Following is more from the referenced docs: Each node of the machine effectively consists of a single bit processor, optional floating point accelerator and node memory. The DAP 510 is small enough to fit under a desk, while the DAP 610 is housed in a standard EIA rack cabinet. Both DAP models can be hosted by Sun or DEC VAX computers and workstations. The DAP can be connected to a Sun host via the SCSI interface. Connection to DEC VAX systems is via DR11W or DRB32 interfaces. Connection to the Aptec IOC is supported as well as direct connection to VME bus. DAP 510 DAP 610 Array size 32 x 32 64 x 64 Array memory 8 Mbytes 16 Mbytes (max. of 128 or 512 Mbytes) Code store 512 Kbytes 512 Kbytes (max. of 4 Mbytes) Instruction rate 10 MHz 10 MHz host Sun or VAX Sun or VAX Size 17 x 13 x 20 in. 45 x 25 x 38 in. The present DAP systems are third-generation machines which started with a 64 x 64 array originally installed at QMC (Queen Mary College, University of London). The QMC machine, which had an effective cycle time of 250 nsec, proved highly adaptable to a wide range of numerical problems based on partial differential equations. The performance on large-scale Monte Carlo simulations in lattice gauge theory and molecular dynamics was found to be exceptional and, in some specialized applications such as the Ising model, the DAP outperformed a CRAY-1 by a factor of 10.

AM29818 pipeline register/diagnostic register/writable control store?

by rigdonj＠cfl.rr.com

I stopped by a scrap place and picked up an interesting looking board. It has a number of AM29818 "Diagnostic Resisters" on it. I wasn't familar with them so I looked them up on the net and found this <http://www.national.com/pf/54/54ACT818.html> for an equivelent part. Is there anybody here familar with these that would care to tell me what they are in plain english? Joe

leaky batteries!

by witchy＠binarydinosaurs.co.uk

Hi folks, Whilst getting an old Videomaster pong ready for sale (even though I know nobody will buy it) I discovered it still had its batteries in from the last time it was used - 1970s by the looks of the batteries - and they'd naturally leaked all over the place. I've tried standard Foamcleaner (anti static, natch) to remove the lovely brown stuff but it's not having any of it. Any tips for removal of this stuff without scratching the plastic too much? cheers, -- adrian/witchy www.binarydinosaurs.co.uk - the online computer museum www.snakebiteandblack.co.uk - ex-monthly gothic shenanigans :o(

Emulex UC04 manual

by mcwood＠t-online.de

Hi Bert, A nice guy from the list sent me a PDF. It's basically 80mb. Do you know a place were I could upload it ? Or I could send you a copy on cd to your home adress. Cheers, Marc Hi Mark, In http://www.classiccmp.org/pipermail/cctech/2002-November/004634.html I see you're looking for an Emulex UC04 manual. Did you find it? If you have it available electronically, can I please have a copy? The reason I ask is that I just bought a PDP11/73 and have a problem getting 2.11BSD installed.

It should just work, if SDI disks don't need a low level format prior to OS install. Unfortunately I don't own any SDI equipment.

See http://original.xs4all.nl/elfje/ I see you've found a somewhat-common chicken-and-the-egg problem while trying to load 2BSD on your box. Have you examined "vttape"? It's a virtual tape program that lets you force-feed a PDP-11 via a PeeCee over the console port. I haven't used it, but from what other people say about it, it's probably the least-additional-hardware-intensive way to go. -ethan -- Ethan Dicks, A-130-S Current South Pole Weather at 03-Dec-2003 15:30 Z South Pole Station PSC 468 Box 400 Temp -16.1 F (-26.8 C) Windchill -54.7 F (-48.2 C) APO AP 96598 Wind 13.5 kts Grid 058 Barometer 696.4 mb (10014. ft) Ethan.Dicks(a)amanda.spole.gov http://penguincentral.com/penguincentral.html ------------------------------ Message: 11 Date: Wed, 3 Dec 2003 10:59:40 -0500 From: Ram Meenakshisundaram <RMeenaks(a)OLF.COM> Subject: Transputer box with 4 transputers on ebay To: "'cctalk(a)classiccmp.org'" <cctalk(a)classiccmp.org> Message-ID: <92322E4B3209D511A19100508B55847803673881(a)exchange.olf.com> Content-Type: text/plain; charset="iso-8859-1" Hi, Another auction: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=3445280936&category=3666 This one has 4 CSA TEK boards on its own backplane.

W076/M452 replacement cards

by vrs＠msn.com

Well, it finally happened :-). I was able to talk to my pdp-8L at 19200 baud over an RS-232 link from my PC. Just a cable swap and some dip-switch adjustments and I can talk to my TTY over current loop. However, my TTY doesn't have the reader-run mod. Does anyone have a TTY with reader-run in or near the PDX metro area that I could test with? Thanks, Vince

OT: webserver choice

by waltje＠pdp11.nl

All, This is highly off-topic, but (imho) important enough to just send out anyway. I am moving the www.pdp11.nl site to a new server, for two reasons: - it is currently on one of our production servers, which must stop (for Dutch taxing reasons.) - it will be moved to the colo room of my isp, who have offered to host it to "help the good cause". yay! So.. new server, then. Since it's a DEC Archive, local friends have made sure I understood (...) how important it was that it'd run on Classic Hardware. Trust me, they've mentioned that to no end.... I ended up deciding on an Intel-based box, rather than a VAX or Alpha, mostly because the box has about 400GB of EIDE-based disk storage, which wont happen in a VAX. I decided against an Alpha for other reasons, so ended up with Intel. New machine is a Digital Server 1206, with (now) dual P2/333, but probably with faster CPU's as soon as I find them... the box can handle up to 533, which means it'll end with P2/466's. It has 512MB of RAM- the mainboard wont support more. Disk space is set up using a mirror volume of two 9GB disks off a Mylex DAC960 for the OS, and then a Promise EIDE controller for the four EIDE disks, which are in RAID5 configuration. No problems there. The real bitch seems to be the choice of which OS to run on it. I prefer OpenBSD for such jobs, but alas, that (a) wont do SMP, and (b), much worse, it doesnt support the Mylex. I just did a test install of Linux on it, and that works, so at least I can set it up. So.. remembering the "which OS" discussion earlier, I need a lean distro of Linux with no GUI crap, including all the stuff one'd need for a dedicated web server. Anyone here (Jay?) have put something together, or, much better, have added Mylex to OpenBSD? ? :) Please reply *off-list* , I will summarize later- we dont want a massive debate here.
