All -- < RANT_MODE=1 > Sorry, I never could pass up an internecine fued of the UNIXes.... I'd like to go on the record. I love AIX. And there are a couple of bullet points we've missed in our description of it. The most important is its underlying object repository. This may have been the seed of the AIX vs. AS/400 thread. AIX invented the central system registry long before Microsoft. That's the engine behind its package and device management. It's the underlying engine most of the standard admin commands ultimately converse with. Very un-UNIX - and thank you to the IBM _wunderkinder_ for that. UNIX is a wonderful thing, but why must we live in a timewarp where anything not envisioned in the 1980s isn't "real UNIX". Let's move on shall we? Linux is a good example. It's based on a complete rewrite of Minix, itself a complete rewrite of AT&T System V. By all means, let's preserve the vintage, and don't throw the baby out with the bath water. But why should the UNIX community turn Luddite? IBM as we've all said, did a rewrite of the kernel. Rather than porting System V and glomming on some Berkely additions, IBM re-engineered the code >from scratch. In the upcoming version, they are doing it again to accomodate even more robust enterprise configurations with sub-CPU LPARs and mainframe like accounting/management facilities on a rapidly advancing 64-bit CPU design. It's my own assessment they are moving AIX to the top of the tree for big iron, and moving the zOS hardware toward commodity Linux VMing. It's a move that follows the market's application development trend for enterprise systems. Thee development community writes more for big Unix, so this is perfectly sensible. Just to keep this post from being too out of thread, I might just mention my 10 year old 990 and 390 RS/6000s are still wonderful machines to work on now. I use the 390 as a graphic station (if you could believe it). It scans and GIMPs with the best of them. Only compression routines make it slow down. The I/O's faster than the laptop I'm writing this post on. Okay, < RANT_MODE=0 > Colin

Well, it says you can use GTKWave, and I assume it works, but I myself don't need any pretty pictures: I personally can see whether my logic works right or not from textual simulation output better than from pics. My brain prefers text to graphics in absolutely every area of life. MS

working magnetic drum stores?

by julesrichardsonuk＠yahoo.co.uk

Just out of curiousity, does anyone still have a working drum storage device? wondering if any working examples have survived... I have a half-assed plan to try and find one from somewhere at some point. We have a Sperry unit that's way beyond repair, and don't have anything other than the drum assembly itself anyway (the bearings still seem good though so I might see if it can be coaxed into spinning) - but a working demonstration would be great hooked up to one of the 1960's machines. I gather that telphone exchanges used to use them here in the UK so maybe there are still a few lurking in private hands as they must have been reasonably common at one point. The flipside of course being that they're pretty bulky devices in themselves, and with the low reliability they've maybe all gone to scrap years ago (unlike other peripherals of the area which survived). cheers Jules

Not too long ago I was chatting on IRC and a gal joined the channel I was on. Some guy asked her if he could see her tits. She replied: (@) (@) So ASCII works for porn too. MS

We will be removing these running machines any time between May 1,2004, and August sometime. Are you interested in having these for your museum? They have an interesting device attached to them, called a PCL, which was a early DEC networking system. I haven't talked to the owner, but I would think that they would give them to you. Let me know. Also, I am Looking for a copy of the XXDP-11M+ Diagnostic handbook, or Card. I am looking for the procedure for building a v-1 diag. tape, from disk, to tape.

KA620

But I'm pretty sure now that KA620 was the only implementation of the rtVAX architecture. > My VARM is "Revision 6.1" and is not obviously marked with an edition > number. 1982-05-20, right? I have that one too, it's my first VARM, one of Tim Shoppa's early gifts to Quasijarus Project. The early VARMs, the EK-VAXAR-RM ones, are lovely: 100% pure ASCII, except for boldface section headers the book is line printer output. From the appearance seems to be very close to the DEC internal VAX spec, DEC STD 032 (though not having a copy of the latter it's an educated guess). But then they stopped issuing VARMs in that format, and published it as a book (with ISBN and all, rather than an EK part #). The book version of VARM had two editions: 1st ed. in 1987 by Tim Leonard (listed as the keeper of the DEC internal VAX spec in an appendix to another highly secretive DEC internal spec I have) and 2nd ed. in 1991 by Richard Brunner (wonder what happened to Tim...). I have acquired both of these books recently. Not having a copy of the genuine article (the DEC internal STD 032 spec) I have to live with the published versions instead, so I was trying to acquire as many of them as possible to complete my mental picture of the complete architecture spec and its variations. (I'm designing a new VAX CPU chip, so I have to have a very solid picture of the spec requirements and options and their evolution.) Would anyone perchance have a copy of the real VAX spec, DEC STD 032 aka EL-00032-00 aka A-DS-EL00032-00-0? > I don't recall seeing an rtVAX mentioned in it, and the index > does not list anything beginning with rt-. Yeah, of course the 1982-05-20 VARM predates it by a few years. Brian Chase <vaxzilla(a)jarai.org> wrote: > The 2nd Ed VARM has a section on rtVAX memory management, 11.2.3 on pgs > 422-424.

Table 8-2 on pp. 331-332 lists the SID code assignments, and 16 decimal is listed as "rt/uVAX (chip 78R32)". Knowing that 78032 is the MicroVAX II chip, used in KA630, KA410 (MV/VS2000), and a bunch of other less-known systems (see the SYS_TYPE codes the same table lists for SID 08), it's pretty obvious that the rtVAX 1000 listed by the table as being based on this 78R32 is the KA620. Since the MMU is internal to the CPU chip, the difference between KA630 and KA620 is in the silicon (78032 vs. 78R32) rather than board-level. MS

I still have one that my dad purchased it is still in its original Styrofoam with manual and all the parts I even have the warrantee page and the page with the types of cassette players and TVs it is not compatible with and a program my dad wrote for it my husband was laid off and we need the money or I would hold on to it. It is the first home computer he ever bought I remember going with him to get it Let me know if you are still interested in it and how much you might be willing to pay for it I can send you a picture if you wish tablab(a)kellerits.com
