Laserdisc interfaces

by jeffj＠panix.com

> I think there's at least one Pioneer with a DA15 serial interface, but > I have no idea if there's any sort of standard for them. I think I used to have a Pioneer LDV1000 with a proprietory parallel interface using a small Centronix-style connector. I scrapped it because the power supply was blown, and I got an RS232 interfaced one that plays CAV and CLV with barcode scanner, etc. I just touched the adapter box in my storage unit that converted the parallel interface to RS232 and I have the manuals ... somewhere :-(

Wood's Metal (was Re: Open source, stand alone, ASCII terminal project)

Thank heavens for my Wood's metal desoldering trick > or I would have made garbagge out of the adapter boards. I have a "ChipQuik" kit of some flux and a slug of something like Wood's Metal, presumably the trick you are talking about. I have yet to use it (it's just a free sample). The documentation seems straightorward, though. Does anyone on the list know where to get moderate quantities of Wood's or Field's Metal at reasonable cost? By moderate, I'm thinking of a small number of pounds (kgs). I don't have an immediate use for it, but in the next year or two, I'm considering building a RepRap or a Fab at Home and one of the things on the horizon is printing circuits with low-temp metal on top of printed plastic substrates. I'd like to see how much the metal is going to cost before I go down that route. -ethan

70's view of Army Radar Installation (with computer gear)

by cclist＠sydex.com

I just ran across this page: http://cryptome.info/0001/loc/loc-images.htm It seems that LOC has been rather ham-handedly censoring some of its online historical content. Of particular interest is a shot of computer peripherals (printers, card readers, tape drives), all of which appear to be vintage CDC gear (military versions of the 512 printer, 65x tapes, 405 card readers...). I don't know what the mainframe behind this was, nor does it seem to be shown. Anyone have any idea? BTW, the TIFF images are 20MB each and very high quality--enough so that I could read the CRT displays and the notice of "Volley Ball" and "Hayride" on the bulletin board. Cheers, Chuck

Hard disk material

by wdonzelli＠gmail.com

It looks like sometime in the future I may need to rebuild a damaged magnetic drum. It has some scratches that may be too deep. As a brainstorm, I am wondering about recoating the surface. If I use refined iron oxide, what would I use as a fixer (glue)? What was typically used on early hard disk platters and drums? -- Will

cctech moderator on holidays

by ethan.dicks＠gmail.com

Hi, All, Lawrence Wilkinson <lawrence at ljw.me.uk>, one of the classiccmp moderators, asked me to post a quick note to the list that he is travelling around NZ and can't check the moderator queues as often as he does when he's home. This means that moderated messages will be delayed more than usual, and that if you are a member of cctalk _or_ cctech and post from an address you did not subscribe from, it will take him longer to spot those messages and release them. Unmoderated postings to cctalk sent from subscribed accounts should go through without Lawrence having to interact with them. I'm guessing, though, that nobody has heard from Jay himself in quite some time now. -ethan

PDP-11 Zork Manual: Save $2,348.31

Somewhere, I've seen _an_ original RT-11 app, but not Zork I - maybe Deadline or Starcross. Just the executable, not a disk image. I'd love to see one of those just to poke around on unallocated sectors. I've only recently learned how much cool stuff is on ancient Amiga Kickstart disks (the KS image file only occupies ~256K out of 880K, leaving plenty of space that wasn't zeroed before mastering). -ethan

WANTED: someone to transfer IBM 5110 BASIC programs to modern PC

by tosteve＠yahoo.com

Hello, A gentleman from the East Coast contacted me to see if I can extract old BASIC programs from his IBM-5110 8-inch floppy disks. I have a working IBM-5120 with internal floppy drives, but the serial communications option is not installed in my system. I think the best I can do is LIST the programs and photograph the screen. Any other ideas? Anyone else with a serial port who can do it? Anyone with a spare communications card? Thanks- Steven Stengel

Tragedy in our hobby: Jay West ....

> With the week I'm having, that subject line was decidedly unappreciated. I TOTALLY agree. I hope I have the opportunity to do something really shitty like this to you some day, Evan.
