<Allison Parent is probably correct that Ultrix doesn't have as impressive <a record of robustness as VMS, but there are certainly application-specifi <cases where the system did pretty well. The collection of MicroVAX II part <I have at home mostly used to be the University of Toronto's backbone IP <routers, which ran an early Ultrix (I forget if it was 2.0 or 3.0). True enough. I've found it more solid than the also rans even on PCs but compared to VMS it was more difficult to maintain and less tolerent of faults. VMS was more tolerent of memory page faults(ram parity hits) and seemed to have less trouble with unplanned/undesired shutdowns. I suspect for one reason that was true... VMS was older and had more emphasis so there was maturity plus development effort. On the other hand I've seen UNIX pdp-11s run as long as power and hardware was available. Allison

I have a manual for a Rimfire 6700 disk array subsystem. I also have 2 floppy disks, one 5.25" and one 3.5", each is the Rimfire 6700 Utility Diskette (copyright 1993). I also have 2 copies of a disk drive manual, HP 97556/58/60 5.25-inch SCSI Disk Drives Technical Reference Manual. For whatever reason, these were printed on pink paper.. These are Edition 2, June 1991 Yours for the asking. You pay shipping at post office book rate. -Lawrence LeMay

Classic Computer Auctions List

by edick＠idcomm.com

Well . . . not to suggest that I'd consider eating that paper snackie . . . I've seen lots of dollars made with VIC-20's and C-64's, by guys who could imagine a solution to a problem which could be implemented via the printer port and a little bit of code. While the things were really plentiful at the local thrift store, they cost $5 for the computer and $5 for the power module. It seems to me that the internal bus was sufficiently accessible without sawing or drilling the case to allow an enteriprising individual to build custom hardware which harnessed the otherwise wasted ability of one of these gems, to control a 3-axis milling table, or something on that order. The first time was probably painful, but I haven't thrown away my manuals . . .

Sigh. I'm losing my secret storage room where i've been tossing all sorts of old manuals and such.. So, does anyone need this: Documentation sets for the SGI Indigo R3000 computer. Some printer supplies for a Tektronix Phaser III PXi. We have enough Indy Cameras to sink a ship, but we'll probably keep those for who knows what reason... -Lawrence LeMay

AMD 9511, 9512, Intel 8231, 8232 wanted, will trade National MM57109

by edick＠idcomm.com

Peter Boyle, along with Wayne Wall, at that time, of the Denver Area 6502 users' group, wrote driver routines, perhaps the ones which were used here to patch the 9511 into the Applesoft basic, for the group's Apple users. It would surprise me to learn that anyone still has this stuff, but if they do, you won't find anything much better. He also started on a set of drivers to go with his XPL0 language for the 6502. I'm not certain whether that task was ever completed. The drivers are quite straightforward, due to the device's architecture. However, as I recall, the patching it into the Applesoft basic was a pain. -Dick- ---------- > From: Eric Smith <eric(a)brouhaha.com> > To: Discussion re-collecting of classic computers <classiccmp(a)u.washington.edu> > Subject: Re: AMD 9511, 9512, Intel 8231, 8232 wanted, will trade National MM57109 > Date: Wednesday, January 27, 1999 1:29 PM > > Tony wrote: > > Speaking of which (:-)), does anyone else remember a 9511 card for the > > Apple ][.

Hofacker books [was RE: Ohio Scientific box]

>BTW - I have, somewhere in the basement, the remaining stock >of Hofacker computer - a (at least in germany) somewhat popular >publishing company, that sold more than 120 books and hundreds >of programms thru the early years - Ohio, TRS, Apple or PET - what >ever - from 1977 until 1984 (?) they also published a magazine. Oh boy - one of those for the Atari, called 'hackerbook' was a good referance for writing Atari 8bit device drivers. Sure was fun to make devices interfaced to the joystick-parallel I/O port using Hofacker as a guide. It also showed how to make your own plug in rom carts too, IIRC. Found it in a mall bookstore around '85. Chuck cswiger(a)widomaker.com

AMD 9511, 9512, Intel 8231, 8232 wanted, will trade National MM57109

by edick＠idcomm.com

The 9511 was the floating point unit, and the 9512 was for 64-bit integer arithmetic, I believe. I've actually got one of each of these from back in the old days. They were sort of a calculator for your computer, in that they could be operated faster than the cpu could perform the function . . . MUCH faster.
