The Ne[w|utered] HP (was: RE: The effects of employment)

by Fred.van.Kempen＠microwalt.nl

Hi all, What stuns me about this what seems to be a national effort to wipe out existing knowledge and experience in the various U.S. companies trying to clean up their EOY numbers, is that they truly dont KNOW what they're doing. I did some asking around based on Megan's layoff, and the results are stunning. HP really, deeply and truly has no idea of what they're doing right now, let alone where they're going from here. Corporate HQ announces that the numbers don't look [as] good, so we have to cut on operational costs. And, HP being New (I'd call it 'brainless'- but then again, I'm not part of their staff ;-) they go for the first possible solution: fire people. What would that do in the long run? Right now, their plan is to dump Tru64/Alpha, and to integrate that with the HPSux/HPPA stuff. We'll see about that later (customers usually have their own ideas about that- they forced MS into keeping Win2000 around for much longer than they wanted to ...) but for now, exactly _HOW_ is HP going to handle their support obligations to their enterprise customers? I talked to the CTI of a _Major_ Dutch multinational this morning, which I know uses truckloads of Alpha systems, with both VMS and Tru64. When I told him about the layoffs in the UEG (Unix Engineering Group) task forces, he said: "Oh. So, assuming they clean out most of their brains, which is what this sounds like, HOW can they adhere to their claim to full support until X years after EOL?" Also- I can't speak for U.S. companies and their IT staffs, but in Europe, HP/UX doesn't have such a grand name in Enterprise Computing. It's mostly Sun Solaris on the Exxx boxes, and Tru64 UNIX on Alpha, as far as large UNIX systems are concerned. HOW is HP going to sell this to their customers, without those same customers running off to Sun or IBM, in search for some stability? Anyway. HP has lost its marbles. Cutting operational costs is a good thing, and usually serves a purpose. Ripping off your own balls (I apologize for any ladies reading this..) is not the best thing to do, and will probably leave you without kids later on. Kids that feed you when you can no longer do it yourself. Which might happen sooner than you think... --fred (yes, pissed off, how'd ya guess?)

by ScottRowe＠mail.weber.edu

I noticed that you have alot of 486 SRAM Cache Chips, I have been looking for some to upgrade a computer of mine. I hope this is correct, are they for L2 Cache on the motherboard? They reason why I ask, is because that is what I need. Are they all the same configuration? ie.. (32K x8) for example. Or do you have (64K x8) or 128 versions also. Please email with Information.

Unibus SCSI question

by mross666＠hotmail.com

I've just aquired a tested working Emulex UC17 Unibus SCSI host interface >from a dealer for $50... don't know if I'm crazy paying so much for old Unibus or not! Question is, does anyone have any observations as to any special requirements such a card might have? Long time since I've played with any Emulex... any reason why it shouldn't work in really ancient hardware, such as my 11/20?... something appeals to me about putting a SCSI disk in such an ancient device!

One more screwup with the Ace...

by vassilip＠dsl.cis.upenn.edu

Removing ICs without a good soldering iron is an exercise in futility. About 15 years ago I was trying to remove some ROMs from a 8086 machine (a Japanese machine called Samurai with 2 8 inch floppies, running MSDOS 1.x - it was not a PC compatible, so it could not run anything other than its own version of MSDOS). The machine had a passive backplane with a series of posts on the back so that you could attach probes to the bus lines. I didn't have a proper technical manual, but I did have the schematics and I had taken a dump of the BIOS. The ROMs in question were on the video controller card and were used to store the character bitmaps. I wanted to replace the ROMs with static RAM so that I could change the character set of the machine. Unfortunately I made a complete mess of removing the two ROMs, but a visual examination of the board did not reveal any obvious damage. So I soldered a pair of sockets and mounted the original ROMs to see if the machine worked. Guess what, the fan worked, but I did not get any disk activity and the screen remained blank. Time for the funeral. So I carried that machine to the hardware lab of the University and asked the help of a friend. He was playing with a new (at the time) Dolche instrument that could attach to the bus of a microprocessor and display the code that was running (the actual assembly instructions). So he was quite excited at the prospect of using his new toy on a real machine. We plugged the DOLCHE to the Samurai backplane and we found that the processor was running, but stuck in a tight loop. So we looked at the ROM listings and found that the machine was waiting for the vertical blank signal. So we used a probe to connect the output of the video IC to the appropriate line on the backplane. As soon as the probe made contact we heard the floppy come to life. The screen was also working and the machine was trying to boot. We followed the VBLANK trace and sure enough it disappeared under the two character set ROMs. So I had the machine working again, and a war story to tell. Best Regards **vp

Y2K/Y10K for V5.03 of RT-11

by jhfinepw4z＠compsys.to

I am not sure if there is any interest at all in fixing the Y2K bugs in V5.03 of RT-11 and making it Y2K compliant. Since V5.03 has been widely available for a number of years and is able to be legally run under the Supnik emulator for hobby users, I am curious to find out if spending the time to port code (that I did in 1997) from V5.04G of RT-11 to V5.03 of RT-11 is worth while insofar as the Y2K bug fix is concerned. In addition, and at the same time, it would be very effective to add extra code to make RT-11 Y10K compliant and handle years up to at least 9999 CE. Even if you are only going to use the final product, the number of individuals interested in playing a role is important to ascertain. Please express if you would like to at least receive the changes to V5.03 that would make the code Y2K/Y10K compliant. At the present time, I assume there is absolutely no commercial interest in a Y2K V5.03 of RT-11. Consequently, the target of this post is, by default, only the hobby community. The final result will also be licensed for just the hobby community, so it is hoped that ought to prevent any complications as to who will use the changes and whether there will be any attempt to restrict the use of such changes by the hobby community. If there is any commercial interest, please e-mail me off list to find out what might be available. If the interest is what I think it is, I will NOT be receiving any responses at all for commercial use!

If you attempted to send a reply and the original e-mail address has been discontinued due a high volume of junk e-mail, then the semi-permanent e-mail address can be obtained by replacing the four characters preceding the 'at' with the four digits of the current year.

Machines like that were designed to keep the cost as low as possible, and repairability often wasn't a consideration.

First thing is to make sure anything you remove is replaced with a good quality socket, and if necessary that you can repair any damaged tracks with stripped wirewrap wire or similar. How adept are you with a soldering iron? I used to do this sort of thing for a living, and I'm not too far away if you want someone to take a look at it. Did you get the 2114s and Z80 I sent you?

Selling it off. What would you keep ?

by lgwalker＠mts.net

I am at a point where I am thinking about divesting myself of the majority of my computer collection. Partly needed bucks driven, partly tiring of it all. A small museum is unlikely and I have other unfulfilled interests which I might focus on as an old fart. Likely on E-Pay because we're a notoriously cheap (or poor) lot. What would the list retain if they were cutting down or getting rid of the majority of thier collection and keeping enough to keep thier hand in. The game machines are easy and the first to go. I would think of retaining an IBM PC and another good DOS box. A CP/M machine. Maybe a Rainbow and let the Kaypros, Osborne, and others go. A hip old laptop, In my case a Grid 1520 and my Sharp handheld. Maybe one old early box like my Micom, H-89. or TRS m.II An Atari 8-bit and / or CoCo 3 An ST and Amiga 3K An IBM PS/2 likely the 8590, altho who would want 8580s, a more significant machine. Maybe one kept by default. And a newer DOS box and laptop. And then looking at this exclusive list it won't be easy. Lawrence lgwalker(a)mts.net bigwalk_ca(a)yahoo.com

ADM-3A lower case

by c.morris＠townsqr.com

I' ve been intermittently looking (for many years) for a lowercase 2513 for my ADM-3A. I was really happy to see your post and find that others are interested in restoring this '70's nostalgia piece! I remember in 1977 how impressed I was with the blazing 1200 baud modem speeds, since the hardcopy Decwriters at the Univ. of Maryland were 300 baud. (Also I have a working rackmount PDP-8/I, with a "University Computing Company" front panel). I wore out my keyboard this weekend searching online for a 2513. Pure unobtanium. GI made them (I believe the p/n was 2513CGR-002 for the lowercase? -001 is in the socket so obviously the uppercase). Just as well I didn't find one, I never knew the address lines were flipped.... or am I misunderstanding and it is the direct plugin? thanks Charles

My first good find!!!

by philpem＠dsl.pipex.com

Hi all, I'm currently in a very good mood because I've found a Jupiter Ace in near-mint condition, complete with 16k RAMPack, intro tape and a copy of the book "Jupiter Ace FORTH Programming" by Steven Vickers. All this, including the polystyrene box for the rampack (and rampack instructions) cost me the rather feeble sum of two British pounds. Now, there is a catch. The machine didn't come with a power supply. So, can someone with an Ace, working PSU and a multimeter please tell me what the polarity and voltage of the PSU's output is? I'm hesitant to power up the Ace in case I end up fouling up the settings, with fairly predictable results. Thanks. -- Phil. philpem(a)dsl.pipex.com http://www.philpem.dsl.pipex.com/

Solaris 2.4

I have old Sparc Sun machine which I would like to run on Solaris 2.4, not newer. I have Solaris 8 from a few years ago when I paid Sun $75 for CDs but I do not want to run this version or the 2.5 I have from another machine. Does anyone have Solaris 2.4 CDs that they could sell or copy for me? Please note that I am not looking to violate copyright law but I do need to get 2.4 and not some later or earlier version of Solaris.
