I was quoting my memory of a DEC ad in the WSJ, which now that I go check, says the -11 was "the best-selling computer in the world" (the ad was in 1980). There are a number of possible explanations as to why it makes this claim: - some marketing person made it up - they were only counting things that were general-purpose (i.e. came with mass storage and compilers) - they didn't consider micros as "computers" (many were used in things like printers, etc, and were not usable as general-purpose computers) Etc, etc. Noel

IDOL/VS Manual

by silent700＠gmail.com

I am preparing to scan this manual on the IDOL/VS database system, which was initially a product of "Systems Specialties" but was later purchased by MAI for their Basic Four systems. I can't find any documentation on this product on Bitsavers or anywhere else. If anyone is aware of this manual online, please let me know. And if anyone wants the original once it's scanned, I'll be happy to send it for the cost of postage from 60070. J

Miscellaneous Equipment for free (Mostly DEC) in Lexington KY

by useddec＠gmail.com

Any Uni-bus or PDP8 items? I have plenty of boxes or I would jump on it, but if some one picks them up I have most of the boards.

> From: Guy Sotomayor Jr > I think it's also telling that the IETF uses the term octet in all of > the specifications to refer to 8-bit sized data. Yes; at the time the TCP/IP specs were done, PDP-10's were still probably the most numerous machines on the 'net, so we were careful to use 'octet'. Although the writing was clearly on the wall, which is why it's all in octets, with no support for other-length words (unlike the ARPANET, which sort of supported word lengths which were not a multiple of 8 or 16 - which was actually use to transfer binary data between 36-bit machines). > It *may* have been the IBM 360 that started the trend of Byte = > 8-bits Yup. And then the PDP-11 put the nail in that coffin (and in 1980, there were more PDP-11's, world-wide, than any other kind of computer). Noel

Microcode, which is a no-go for modern designs

by technoid6502＠gmail.com

What defines a 'modern processor'. The term is pretty slippery. The Crusoe used microcode to emulate x86 and could therefore emulate any processor architecture Transmeta wanted. Crusoe was a pioneer in the low power market, the processor dynamically clocked itself in very small steps depending on need. This is a familiar feature now but was pretty revolutionary for the time. Interestingly, Linux Torvalds was in on the design and was on the board of Transmeta. A fair number were sold to Sony for their VIAO series of notebooks. Does Crusoe qualify as a 'modern' processor? In my book yes, but I have a very old book.. :0 best, Jeff

uc04 + scsi2sd ?

by jacob.ritorto＠gmail.com

Hey all, Anyone know whether the Emulex UC04 works with the sd2scsi? I just bought a uc04 and it won't talk to any of my old scsi disks, seems to think there's supposed to be a "controller" in between :\ yuck. thx jake P.S. While I'm at it, anyone know how to get UC04 to talk to directly to plain scsi disks and tapes instead of these lunatic ESDI controller bridge things?

KD11-E/EA microcode flow diagrams

by jnc＠mercury.lcs.mit.edu

The copy of the KD11-EA engineering drawings (in the 11/34A Field Maintenance Print Set, MP-00190) on Bitsavers is missing most of the pages that hold the microcode flow diagrams. I have a set of the KD11-EA FMPS (MP-00192), which does have all the missing pages, which I can eventually scan. However, in the interim, the 11/34 Field Maintenance Print Set Vol. 2 (MP-00082) on Bitsavers has a complete set of microcode flow diagrams for the KD11-E (pp. 15-40 of the PDF), and they are almost identical to the KD11-EA diagrams. The only difference I can see (I compared page by page, to see if each page had the same microinstructions on it) is that on sheet 17; the last microinstruction for RTI/RTT has been moved from 002 -> 744. (The actual microinstruction contents seem to be the same.) I don't know whyo the changed address; I originally thought that perhaps they had to re-do the IR Decode ROMs when they added floating point, and they needed the original location to handle the start of the floating point microcode, but that doesn't seem to be the case.
