Does anyone have a spare/old cleaner tape for a DLTtape IV drive? I have one of these drives installed in an old Sun but the 'head clean' light has now illuminated. Thanks.

Need some phenolic G pattern Vectorbord

by swtpc6800＠comcast.net

I need some small pieces of phenolic G pattern Vectorbord(tm) for my Vintage Computer Festival exhibit. The G pattern has holes on 0.1 by 0.2 inch centers. I need pieces about 3/4 by 1 1/2 inches (or larger). Here is a photo of a sample. http://www.swtpc.com/mholley/MITS/VectorBord_G.jpg I will trade or pay for it. Does anyone know of someplace that still stocks it? I can reuse old board. I will be reusing the board in the picture. Michael Holley www.swtpc.com/mholley

Prime minicomputer simulator?

by doug.jackson＠ewa-australia.com

Sellam - When I was in school, we had a perfectly functional PDP 11/45 with VT52 terminals (about 16 or so of them). The machine was in the computer room, with all of the hardware accessible (I remember getting into strife when I wrote a program to output human readable text strings to the PTP......) One semester break, they rolled out the DEC machine, and rolled in a Prime. It was horible, and none of us actually got any useful work done for the first couple of months, while we came to grips with the new operating environment. I can't actually say that it was nicer to use than the PDP 11.... It was newer and shinier. (And it lacked the paper tape punch) In fact, I would suggest that the system was so despised by its users, that they had to put it into a cage at the back of the room, because people kept resetting it. The cage didn't work, because somebody discovered that you could still use a long broom handle to hit the reset switch..... Makes you wonder about the sanity of replacing a system that could be kept out in the open, where people didn't muck with it, because it "Just Worked" (tm), with another system that was so despised that users wanted to turn it off? Sorry, no, you won't find an emulator from anybody who enjoyed the DEC hardware..... Doug

DEC Rainbow 100 Plus CRT

by les＠hildenbrandt.com

You might try taking your CRT to a television repair shop and asking to have the CRT "rejuvenated". There is a piece of equipment they may have which will bring back the brightness on your CRT for quite some time. My experience has been one to two years added life the first time the process is used. Additional applications are less successfully. Here is a link to the equipment used for this process on ebay. I have this same piece of equipment and have done hundreds of CRTs with it. http://cgi.ebay.com/Beltron-System-Picture-Tube-Restorer_W0QQitemZ290149557… There is another type of equipment which is made for the same thing which works by sending a spark (high voltage discharge) between the elements in the CRT, I have destroyed picture tubes with that type of equipment. Good luck! Les

Large computer rescue - any collectors in the VA/PA/DC/WV/NC area?

by wmaddox＠pacbell.net

I am arranging a large vintage computer rescue, and will be on-site Thursday and Friday to inventory the equipment and make arrangements. There will be scrappers coming next week, so time is off the essence. From the most recent photos I have been sent, it looks like there may be more material there than was previously indicated, and possibly more than I will be able to handle. It is likely that I can set aside material for other collectors. I would be looking to get firm commitments over the next few days while I am on-site, as it may be difficult to get the owners to hold on to it otherwise. Material that may be available include Modcomp IIs, IBM 729 keypunch, 9-track tape drives, and possibly some Honeywell gear. Please contact me if you have a serious interest and ability to remove this sort of gear, about 4.5 hours out of DC. -- Bill

SciFil Cons - UK retro show thoughts

Wang items

by wdonzelli＠gmail.com

I have a medium sized Wang system available for free, snagged with a bunch of Data General equipment I was saving for a fellow list member. Neither of us are Wang fans. This is a Wang VS45, with a console terminal, printer, a comms box, and a Wang/CDC 80M 14" drive. Included is an unopened pair of boxes, apparently a Wang enlargement kit, to get this machine up to a VS65 - probably some boards, a new power supply, but no special cremes or pumps. There is software (VS operating system distribution) and docs, but these may go to Al. I am not sure about this yet. The VS45 is a cube about 2 by 2 by 2 1/2 feet, but really not very heavy (200-250 pounds). The console is remarkable, as it is the only Wang tube I have ever seen that is not screen burned. The printer is a pretty standard printer, about 70 pounds. The comms box is not too big either. I can probably deliver reasonably close to 10512 quite inexpensively. Of course, if someone a few hundred miles away wants this stuff, I can also deliver for a reasonable charge. I do not really expect to get anything for the machine, although I would not turn down a trade or bribe. -- Will

Simulating VAX/VMS in SIMH

UK retro show thoughts

by lproven＠gmail.com

I've tried to make a couple of points which seem to have sunk unnoticed. While you're all happily arguing about the comparative virtues of various models of generator, I have pointed out that there are already very large-scale computer shows happening in the UK on a regular basis: the commercial LAN parties. If a venue can handle a thousand plus PCs, it can handle a few hundred vintage computers. These places would seem to me to naturally be high on the list of candidate venues. I asked for commentary about the venue for the largest of these, Multiplay. http://www.multiplay.co.uk/ There is one this coming weekend. Perhaps someone in the area - Newbury - could pop over and check it out briefly and report back? Are listers even /aware/ that there are multiple such events every year in this country with literally *thousands* of gamers attending, the majority bringing their own hand-built high-end customised PCs to play on? The custom PC building fraternity is probably the biggest computer enthusiast scene or group in the world today. It's relevant to us. Highly relevant, I submit; their attendees could be some of ours, for a start, and their organizers could potentially tell or teach us a lot. Secondly, there is an existing UK retrocomputing event, although it's not that regular. It's CGE-UK. Here are a couple of reports from past ones: http://www.ukretro.co.uk/cge2004.htm http://www.consolepassion.co.uk/cge-show-report.htm http://www.acornelectron.co.uk/eug/revs/misc/r-cge.html I was at one of these - I don't remember now if it was '04 or '05. It was good fun. Strong games emphasis, which is of little interest to me, but a vast amount of fascinating hardware - all manner of 1980s exotica and obscurities, plus stuff from the '50s, '60s and '70s. For instance, as a child of the (computing) 1980s, I punched my first ever punch card and I handled some core store for the first time in my life. Several list members were there exhibiting. Care to stop debating generators and start making some constructive suggestions, folks? :?) For what it's worth, I was (somewhat peripherally) involved in the running of the 2005 World Science Fiction Convention in Glasgow. I know a lot of people involved in running SF cons and have some useful contacts from that field; I attend up to half a dozen such events a year. This may not sound terribly relevant, but the Worldcon is the largest amateur-run event of any kind in the world and it happens without fail every single year and it's been running for more than 60 years now. There is much we could potentially learn from them. They know how to put on a big event for hundreds or thousands of attendees with no professional help or involvement and a starting budget of zero or close to it. -- Liam Proven ?

FORTRAN T-shirt (Brent Hilpert)

by brian＠quarterbyte.com

Wow, Chuck, that was some great sleuthing there! Thanks. I'm still wondering how on earth that demonstration snippet ended up on a T-shirt, but the owner really wasn't interested in talking about it. First off I don't think he spoke much English, second, I speak hardly any Spanish, and third, I think he found it impossible to imagine that someone was really that interested in the shirt. He probably thought I was hitting on him. (I have to admit, it's one of my more tired pickup lines: "Hey, is that FORTRAN on your shirt?") In any case he kind of squirmed around and wouldn't stand still long enough for me to really read it carefully. I had a second, third and fourth glance at it as we snaked through the check-in line at the airport. Interesting that the last word of that "STATEMENT NOT IN LANGUAGE" was missing from the shirt. Anyway -- thanks for solving the "Where did it come from?" half of the mystery. The "How did it get here?" part I'm afraid is unanswerable.

SCSI TK50 and writing tape

by ian_primus＠yahoo.com

My attempts to boot the MicroVax continue: After much digging around at the house, I finally found another TK50 cartridge. This one is in good condition. I cleaned my SCSI TK50 drive, and mounted the tape. It read fine, I was able to dd the contents (one ~70mb VMS data file, with header and trailer) off the tape and onto my PC. So far so good. I erased the tape, and tried to write the NetBSD boot.fs to it. dd if=boot.fs of=/dev/nst0 bs=512 And the drive whirred to life, shoeshining tape back and forth,but actually making progress through the media (it was accumulating on the take-up reel, anyway). So I let it run. Eventually it failed with an I/O error at a point where most of the tape was out of the cartridge. It took over an hour to get there, and only made it through one length of tape (no track change/reverse) Rewind, erase tape again. So, I tried just plain 'dd if=boot.fs of=/dev/nst0' without specifying the block size (although from what I've read, NetBSD wants a block size of 512 to boot) That shoeshined like crazy too, so I stopped it. Try again, with a block size of 16k (the same block size I used to read in the tape). Still no go, it still shoeshines, but not quite as much (barely). What do I need to do here? How long should it take to write two and a half megabytes of data to tape? Thanks! -Ian

68661 EPCI woes. Can anyone help?

by river＠zip.com.au

Hi, I've connected a 68661 EPCI (Enhanced Programmable Comms Interface) chip to an 8085A system. It is the "C" variant, so it requires the 5.0688Mhz Xtal. It's all connected right, and I checked with the CRO and it is being selected and the 5.0688Mhz TTL signal is accurate and clean. However, the terminal it connects to just gets garbage or sometimes doesn't show anything at all. I put a CRO on the Tx line and the signal is RS232 compliant and data is going out. I tried the terminal with a working system and it works fine. I think I may be programming the chip wrong. I assume, according to the literature, that I set up the Mode register for Internal clock x1 internal clock for async comms. I then program the necessary 4-bit code for the speed I want. However, the datasheet shows the speeds with x16 clock. So, I tried programming it with x16 internal clock, but still no luck. Also, the data sheet says when using async that you use the x1 clock - which I did originally - yet the sheet shows the speeds with x16 clock. I'm very confused. All I want is 2400bps, 7data, no parity, one stop bit async. Has anyone used the 68661? Seeyuzz River

Modern PC's and old ATA drives?

by healyzh＠aracnet.com

I'm trying to recover data from an old Conner CFS420A (420MB) Hard Drive for someone. http://www.seagate.com/support/disc/specs/ata/cfs420a.html I've tried hooking it up to my two IDE-to-USB cables, I can't see it on my Mac when connected to either. I can see it on my WinXP system when connected to the older cable (which oddly enough doesn't like most HD's I've plugged into it). However, I don't see any sign of partitions. When I plugged it directly into the motherboard, the BIOS complained and seemed to indicate 0MB. Do modern PC's have a problem with really old HD's? I'm told that either Win95 or Win98 was on the drive. Will a HD report info about itself, even if it is dead? Thanks, Zane -- | Zane H.
