DEC/Compaq Collection Arrives Tuesday, December 14!

by spicer＠computerhistory.org

Hi Everyone! The largest single remaining collection of historical DEC equipment in the world arrives at the History Center in three 51 foot tractor trailers this coming Tuesday, December 14 and Thursday, December 16th. Thanks to Compaq Corporation, this tremendous "family tree" of DEC equipment will be preserved for future generations to enjoy, study from, and marvel at. Thanks to Compaq also for underwriting the shipping of this unique collection to the History Center in Mountain View where it will form part of the Center's permanent collection. Highlights from the donation include: VAX 11/750 VAX 11/780 VAX 11/780 Eastern block clone VAX 11/730 VAX 8300 VAX 9000 LINC 8 PDP-1 PDP-4 PDP-5 PDP-6 PDP-7 PDP-8A/E/L/M PDP-9 PDP-9L PDP-10 (KA) PDP-11/23 PDP-11/40 PDP-11/60 PDP-12 PDP-15 VT52 VT320 VT100 VT100 AA GIGI Hundreds more items including tape drives, disk drives, manuals, line printers, sfotware, museum displays, &c. These items will form the backbone of a new exhibit, scheduled to open to the public in January, 2000, on DEC's many pioneering contributions to computing. I will post images of the unloading for everyone within the next few days at the following URL: http://www.computerhistory.org/events/latest/ In the meantime, if you have any questions about the donation or about the History Center generally, please feel free to drop me a line.

*Snort!* One of the few places I've seen that makes the prices on E-Bay look cheap. Their target market is definitely *not* hobbyists.

Silly dealers and comments.

Creative only resells cdrom drives that they could find cheapest batch of that. I rather not to. > $9.59USD for 1 CD-R Media??? We sell 'em $15 for a box of 10... That's would be good quality CD-R media like TDK, KAO, Sony etc. Cheap cd-r's do cause problems. I just heard from my friend who tried Memorex and few other "inexpensive" brands and it didn't do very well. What is the brand of those box of 10 cd-r your business are selling? No, not from that dealer. From reputable resellers when I buy stuff. Wizard

There was a lot of local interest in these machines back in about '78. California Digital, a sometime surplus vendor, ran ads in the mags of the time, e.g. BYTE and Kilobaud, for the digital cassette drives that went on these WP machines. Out here, in the hinterland, we thought those would be a potential improvement over the audio cassettes many of us were using to store data, hence we jumped on 'em. Wayne Wall wrote a simple loader/saver to run with them and, ultimately, Peter Boyle, author of the XPL0 language for the 6502,et al, wrote a floppy file system which Wayne Wall adapted for these tape drives. This later reappeared as the "APEX" os for various 6502-based machines. Unfortunately, Chuck Robertson and I were the only ones who went so far as to package a pair of the drives together for use on the same system. Chuck modified the "TFS" tape file system for use with a pair of drives, but the only copy of that was damaged beyond repair during a fixit session between Wayne, Chuck, and me, (I wasn't even smart enough to be dangerous where this TFS stuff was concerned) and the TFS then slid into oblivion. Floppies, in the meantime went down in price, and someone gave Wayne Wall an Apple-][ . . . so you can imagine what happened to the tape drive effort. It only held about 250 kB, on a 60-minute audio cassette, and it took about two minutes to run the tape from one end to the other when searching for a record. Nobody had yet thought to put the directory in the middle of the tape. Once one had used a floppy there was no chance he'd want to use these for a file-oriented OS. Oh, well. I still have the box with the pair of drives in it, by the way.

CoCoLinux (was: I am buying someone a Sun SPARC?. What do I

by allisonp＠world.std.com

<Based on the info I found there about three months ago it looks as if the <UMDA/66's are about the same as a U2W drive. To get the real advantage yo <have to go with RAID and disk stripping. Also, unless I'm misreading thing <UDMA/66 puts about the same load on the processor as SCSI. Yes, SCSI is <still superior, BUT the difference is so slight that you have to ask if th <added cost is worth it. Yes this is all bogus. As a single drive UDMA faster but two scsi drives are still faster as with UDMA (Still IDE) you can only talk to one spindle at a time. SCSI you can have seven on like and with some of the fancier stuff you have the ability to talk to all of them! This makes a real difference if you have system on one, Swap on another and Data on a third. When you interleave like that with queued IO then the difference is substantial. Also RAID with IDE is really flakey! Allison
