Hoping some of the people here can help, I'm trying to compile a listing of hardware that versions of the Spacewar code were ported to after the PDP-1 during the 1960s. There was the PDP-6 version which was done at Stanford SAIL, and there were the PDP-7 and 8 versions which appeared in the DECUS catalog in the early 70s (which means they could have technically been done in the very late 60s), and the early 70s PDP-10 version (which was just a port of the PDP-6 version). Is anyone aware of any non DEC hardware it was ported to in the 60s? I haven't been able to find any concrete evidence that it was on anything other than DEC hardware in the 60s. Thanks! -- Marty

VAX 7700 CPUs, CI cables

by tshoppa＠wmata.com

OK I found some hanks (chopped up from computer room removal) of old blue "thick" CI cable. I was actually gonna take it home and use it for some recabling of my radio station anyway when this subject came up on cctalk. Externally it is 0.4" like many RG-8 and RG-213 types. Internally the center conductor is 11AWG, silver plated solid copper. Yep, silver plated. The dielectric is 0.238" diameter polyethelyne foam. Again, a little smaller diameter than usual for RG-8 types, but I think in ratio with the inner conductor being smaller and the properties of foamed poly, gives 50 ohm impedance. Then, the amazing thing is what's outside the dielectric. There is a layer of foil, a THICK layer of braid, then another layer of foil, then another THICK layer of braid. I don't think I've ever seen a RG-8 type coax with 4 layer shielding. Most RG-213 types have a single thinner layer (and some have foil). I don't think the braid is silver plated, I think it's just tinned, may test that out later. If you wanted to put crimp-on N or UHF connectors onto this stuff, the funny dielectric diameter might cause some heartache, as could the extra thickness of the double braids. I have some hanks of "reddish-orange" DEC Thicknet Ethernet cables too, will check out what's inside them. I seem to recall them being solid polyethelyne dielectric but it's been more than a decade since I cut into any. Tim N3QE

Backing up a usb device sure but as Cindy pointed out its likely a poor backup media itself. Some friends and I all had 64mb flash drives back when they were new. We all lost our copies of some source code we had been using it for (portable coding drive so we could use each others systems and have our progress).

Practical Peripherals ProClock software? (Cindy Croxton Electronics Plus)

by wheagy＠gmail.com

Thanks. However, as you mention, this is a software package that is different than the software that came with the ProClock. It looks like this Comm software supports the ProClock, but does not provide the functionality of the original software. Also, trying to unpack this package, gets me into some odd circular exercise. It goes through two or three iterations of different package archive formats and ends up back at the original package. Any other leads to the Practical Peripherals ProClock software?

I was just looking at some of the old CI cables in the computer room floor. This is all bought-from-DEC stuff from early 1990's. The long ones are typically blue and labeled "12 AWG". They look a lot like RG-8/213 types. There are some skinny jumper cables on the CI panel internals that look to be a much skinnier kind of coax, also blue, looks like RG-174. In the "real world" I am much more likely to see LMR-400 or Belden 9913 specified today, than the RG-type specifications. Tim.

Western Digital My Book World Blue Rings "NAS" controller uses

by saquinn624＠aol.com

Recently came into posession of a WD "Blue Rings" NAS setup. I've rapidly come to the conclusion that it really isn't very good as a NAS, and doesn't even do what it's supposed to (I can't even get SSH to stay up or reliable connections from computers). It has a ARM-based board with an Oxford OXE800, VIA Ethernet, onboard USB, provisions for a serial port (provided I supply a level converter to go to RS-232 from the supposedly "standard" 3.3V to a real standard). The big downside is the BGA RAM chip with only 32MB. I guess it's probably in the junker category since there really isn't any way I can expand the RAM (1 BGA 256Mb DDR chip, no extra pads), but I thought I'd check because I've been interested in the Pi for a bit and then this dropped into my lap - any thing that can be done usefully with this HW?

In the market for hard disk drive for a PDP-8/m

by steve＠tronola.com

Hi Folks, I have been making good progress restoring a PDP-8/m and would like to buy a vintage hard drive and controller for it. Anyone know where I might find those? An RK05 or Diablo-31 drive would be nice. Will also need an RK8E controller board set. Have had some near misses: A Diablo-31 was up on eBay but it turns out that it's missing a head. Found an RK05 listed for sale on a fellow's site. After I agreed to buy it, haven't been able to get a reply, though. Located the controller listed for sale at another company site. The phone system takes messages but they haven't been returned (so far). Email bounces. Hmmm. Please let me know if you know of any possibilities. Thanks, Steve steve at tronola.com http://www.tronola.com/

It's true, a DD: controller with no working units isn't very useful! E11 doesn't give an error message though, since it doesn't want to be picky about the order of the ASSIGN TT and MOUNT DD commands. For all it knows you were just about to attach files/etc. to DDA.

Osborne 1 Video Jumper

by silent700＠gmail.com

That's what I'll call it, since I don't know the correct term Osborne used. It's the plastic plug with pins that jumper the external video card-edge port on an Osborne 1 portable. Without it, the Osborne either goes into external video-only mode or, according to one doc I read, it will damage the hardware. One of my O1 machines is missing this part. Does anyone either have a spare one or know of any plans out there to build your own? -j -- silent700.blogspot.com Retrocomputing and collecting in the Chicago area: http://chiclassiccomp.org

Left a sore spot despite > them being nice for quick trips or transferring files. I'm still using my 256 and 512MB flash drives. But you have a point; the consumer flash USB drives are not known for their robustness. When customers ask to have data returned on USB flash, I balk a bit, and insist on sending along a CD or DVD with the flash--and then hang onto the data for at least 30 days. Just like floppies, storage environment and handling means a lot. If you're used to carrying a USB drive around in your pocket along with your keys, you should probably have a backup of that data somewhere. I mostly find pen drives useful for sneakernet and substitutes for CD ROMs on systems that lack drives. A useful comparison between SLC and MLC flash: http://www.supertalent.com/datasheets/SLC_vs_MLC%20whitepaper.pdf Speaking for myself, I have data backed up in several places, one of them being off-site in a vault, against the day that we have a sudden 300m rise in sea level. :) --Chuck
