Any Apollo users out there? A chap dropped off a couple of Apollo 400t machines at the museum today (circa 1990 vintage) with numerous manuals. First time I've seen one in years - I remember a room full of them at uni behind a glass partition wall, not usable by us mere mortals, and always wanted to get hold of one since then. Initial questions from the 5 minutes I had free today to actually *look* at the things (damnit!): Anyone (hopefully in the UK!) got a spare Domain keyboard? Both machines work, but only came with the one keyboard :-( I have a feeling the chances of finding one are something like zero... Anyone got install media preserved anywhere? (We've got a backup CD, plus I'll image the hard disks - but a copy of proper install media would be nice) How's the Apollo token ring network physically configured? Presumably something somewhere needs to bias the line at the very least? (We got a cable with each machine that brings the card connector out to a pair of BNC plugs) Any idea what tape drive the systems used (I've seen reference to optional tape drive in the manuals) and if it was just a SCSI device on the bus, or whether it used a custom controller? Any other UK people got any more Apollo stuff they no longer want? ;-) cheers! Jules

KA640 TM

by lists＠microvax.org

Hi - does anybody know of any copies of the KA640 Tech Manual online? I think i've got a blown DSSI picofuse* and i'd like to have a casual flip through the manual whilst i'm away from the system. I've searched Manx and poked Google, both turned up nothing. Cheers guys alex/melt * Terminator not lighting up, first disk in chain never coming online, CPU "Normal Operation Not Possible" errors

OT PCI token ring adapters available

by CCTalk＠catcorner.org

I have 4 Olicom OC-3137 cards available for $3 plus shipping (for the lot, not each). Or, make an offer if $3 sounds like too much. Shipping would be from New Jersey, USA. I will ship them anywhere you're willing to pay for. They are Token-Ring PCI/II 16/4 Adapters. I don't know many people that could use these so I thought I would offer them to the list. For drivers and other info see: http://www.olicom.com:8080/index.asp?item=947 First come, first serve. Kelly

Boot Rom for KDF11-BA

KDF11-B3 isn't one ROM, it's an upgrade kit consisting of two EPROMs plus instructions. It's more usual to refer to the ROMs themselves by the actual numbers or the processor suffix. The ROMs in the -B3 kit are 23-183E4 and 23-184E4, as far as I remember; that's the -BF version, but most versions of the KDF11 ROMs work with MSCP devices. For example, people have used RD31 drives on an RQDX3 with -BE ROMs, although it wasn't officially supported until -BG. The next version was 23-380E4 and 23-381E4, which would make the processor a KDF11-BG. There's a list of ROMs at http://www.dunnington.u-net.com/public/DECROMs/ (see the file called ROMlist). You can see which revisions officially support various MSCP devices in Micronote 43, which you can find in various places including http://www.ibiblio.org/pub/academic/computer-science/history/pdp-11/hardwar… BTW, the EPROMs for a KDF11-B are unusual 24-pin 8Kx8 devices; normal 2764-style 8Kx8 devices will not do because they're 28-pin. -- Pete Peter Turnbull Network Manager University of York

1/2" tape cleaners?

by aek＠spies.com

> Does anyone know anything about 1/2" tape cleaners? -- Yes, they do pretty much what you describe. The problem is they used consumable cleaning strips which have been unobtainium for at least 15 years.

Some PDP-11 info (was Re: C compilers for RSTS/E?)

Once again proves that not ALL women are Weendoze pee sea lusers, there DO exist ClassicCmp-friendly and even ClassicCmp-appreciative ones if you take the time to seek one out and don't settle for less than what you really deserve.

She worked as a UNIX sysadmin for 10 years but could use a refresher, and it's always good to have a manual that corresponds exactly to what's actually running.

SpinRite?

by jfoust＠threedee.com

Steve Gibson shouldn't be a strange name for this list. Google tells me that SpinRite's been mentioned a few times in 2003 and 2004. I recently bought a copy of his SpinRite and I'm trying to get my head around exactly when it's useful. The manual isn't much help. Right now it's chugging away on a circa 1987 floppy that lost its shutter, rattled around in an envelope, and today has CRC errors. Not a rare disk, just something I'd like to see if it can recover. It's busy re-reading bad sectors hundreds of times to make its best guess at the data. A few days ago I tried SpinRite on a contemporary PC's hard drive that would error-out when writing to two spots on the disk. At its strongest correction level, SpinRite found the errors but the disk wasn't "repaired" in the sense that I expected: I thought it would somehow map-out the areas that had errors, and let me continue to rescue the drive's data. It didn't. Writing to the drive still failed. (I successfully read both partitions with a Knoppix CD and with R-Studio NE, but I wanted to bring the system back to life enough to let HP's WinXP create its recovery CDs.) So to keep this on-topic, when exactly can SpinRite help rescue old hard drives and floppies? And to state the obvious, SpinRite can't raise the dead. I tried it on a drive that was alive enough to be recognized by the BIOS, but if SpinRite can't make it spin or read, it can't help. - John

access to BIOS of DECpc

Sorry, Henk. I *do* have a plain version, somewhere, that works with Seagate and Toshiba disks (and presumably others, as it seems to be a non-specific OnTrack version, V.7.09). I've sent another copy to you. -- Pete Peter Turnbull Network Manager University of York

C compilers for RSTS/E?

by healyzh＠aracnet.com

What C compilers exist for RSTS/E? I'm aware of DEC PDP-11 C V1.2, is there anything else/newer? I assume there is no way to get GCC to crank out RSTS/E binaries. Zane
