I just received about 80 HP Cassette tapes today, and have no idea what these things might be used on or for. They appear to be about DC-100 size and have names such as "64850-10005 Z8 asm/lnk", "64815-10002 68000 Pascal Compiler", "64816-10005 Z8001/2 Pascal Compiler", "Z80 Emul/Asm", etc. Anyone have any idea of what machine these things might be used on?

I have the full list available from DSN, but it isn't complete. I can't post it here, though, due to it being copyrighted, but I can post VUPs for requested systems from the list, if you ask. The numbers above are the VUPs. The DSN listing for the /90 and /90A are off by 10. I got ambitious and ran some more tests. The /90 is 32-33 and the /90A is 38-39. The VAX 7730 systems at work are 150 VUPs. What's interesting when reviewing the list is to see how the bus architecture impacts the VUPs on identical CPUs. For instance the 7610 is 35 VUPs but the 6610 is only 32 VUPs. -- Eric Dittman dittman(a)dittman.net Check out the DEC Ethusiasts Club at http://www.dittman.net/

someone grab that TU81+ in St Louis please?

by gunther＠aurora.regenstrief.org

Hi, a TU81+ (9-track tape drive, the latest and best that DEC came up with) is up on ebay with only 17 hours to go. It is in St. Louis. So, Buckaroo may want to get it. I think someone should drop in a bid on it just so it is not lost in the dumpster. I have already two of those outstanding (still need to actually go and get them.) The TU81+ works nice with a VAX 6000 or a UNIBUS vax. Not sure the smaller 4000s have an interface, they probably do. The interface is the KLESI on the BI bus (it's actually a UNIBUS adapter with the TU device driver right on the same card and no way to connect more UNIBUS.) http://cgi.ebay.com/aw-cgi/eBayISAPI.dll?ViewItem&item=1275105774 -Gunther -- Gunther Schadow, M.D., Ph.D. gschadow(a)regenstrief.org Medical Information Scientist Regenstrief Institute for Health Care Adjunct Assistant Professor Indiana University School of Medicine tel:1(317)630-7960 http://aurora.regenstrief.org

VAX to play with

by dec.parts＠verizon.net

Hi Bill, I don't mind putting my VAXstation 4000/60's, "box only", up on eBay, starting at $1.00, under their "Auction for America" program where eBay donates the selling price to the NYC WTC Disaster Fund. 8 Mb on the board. Both checked to power up and generate video output. You scrub the magic marker markings off the front which is easy to do with isopropol alcohol and comet. However, regardless of how eBay wants to run that program, packaging materials ( low cost because I get them wholesale ) and shipping costs ( low cost because I ship FEDEX Ground at the FEDEX Center ) would have to be covered, else buyer picks up. But with "buyer picks up" terms, it should sell dirt cheap. Sincerely, Bennett > Speaking of which, anybody know where I can get a decent desktop > VAX to play with again? VLC or better... > Bill

who's got an M88k Aviion?

I'm just catching up on my Classic Computer reading... I've got four DG AV 4300's sitting in the next room. Each of them has a QIC tape drive. I got them without documentation and I haven't had time yet to even boot them up. If someone has instructions on how to break into root I'd be happy to try it out, and/or if there's a way to read the NVRAM without booting the OS I'll be happy to try that, too. BTW, I'd love to trade the 4300's for classic HP gear... Cheers, Dan www.decodesystems.com/wanted.html

Or you might try a 5 BNC variety Sony multisync, just hooking up R, G, and B. or if you have a multisync with a HD15M pigtail, I have hooked these up by coming out of computers with BNC video out by connecting to a BNC to HD15 cable hooked up so that the BNC's are to the computer, then used a HD15F-HD15F gender changer to join the BNC to HD15 cable to the monitor's HD15M pigtail. Just some experimental options to possibly try. Sincerely, Bennett

Maybe the /90 is 32 VUPs and the /90A is 38.8, which would make sense if the list on DSN is off for both system. What leads me to believe the DSN listing is in error now is I just ran a test program on a /90, 90A, /400, and /500, and the numbers for the /90 and /90A are way off from what I'd expect if the ratings from DSN are correct. I'm going to run some tests this weekend to try to get better numbers. I wish the original DEC test program was available. -- Eric Dittman dittman(a)dittman.net Check out the DEC Ethusiasts Club at http://www.dittman.net/

paging Brian Chase

by gunther＠aurora.regenstrief.org

Hi, does anyone know where Brian Chase is? He dropped from my radar screen about two months (or more?) ago. He used to live in Bloomington, IN, not far from me, and we had hauled the VAX 6420s from my workplace in spring this year. He wanted to check out some job opportunity in California, and then he was never seen again. Does anyone have more recent information? His Web site still exists, without any news however. thanks, -Gunther -- Gunther Schadow, M.D., Ph.D. gschadow(a)regenstrief.org Medical Information Scientist Regenstrief Institute for Health Care Adjunct Assistant Professor Indiana University School of Medicine tel:1(317)630-7960 http://aurora.regenstrief.org

Cromemco 16FDC and IMSAI front panel

I'm thinking that some CPU boards expect the front panel to ground one of these signals when the panel is putting something on the data bus via the panel connector (and the CPU board should therefore use the data bus on the panel connector instead of the one on the motherboard). Maybe I am confusing this with some other signal? I ran into this in 1989 with a CCS Z80 board and no-name chassis with apparent 696 motherboard. Took me a while to figure out why it wasn't coming up. -Frank McConnell
