Are the HP9100 and HP9810 calcualtors really RPN machines?

by ard＠p850ug1.demon.co.uk

Subjet: line says it really, but I think I should explain... Are the HP9100 and HP9810 calcualtors really RPN machines? I think not. You ahve 3 registers, called X(Keyboard), Y(Accumulator) and Z(Temporary) which appear to be a stack. But it;s not really as stack IMHO. Entereing a number form the keyboard puts it in X, leaving the other 2 registers unaltered. At no time is there an automatic stack lift (AFAIK). THere are functions to effectively push and drop the stack (if it is one:-)) and to roll it round. Arthmetic operations perfrome something like Y:=Y(OP)X. Again, there is no lift or drop, there is no change to any register other than Y. 1-number operations normally do X:=f(X), at least one does Y:=f(Y), though. Again nothing else is changed, no lift or drop. You can get the user manuals from the Austalian museum site if you want ot read up on this... My (considered?) opinion is that it's certainly a postfix machine in that you enter both numbers into Y and X before doing an arithmetic operation. But becuase of the lack of automatic stack operation, it's not an RPN machine? What about the other 'RPN' desktop machines (friden, etc) Any thoughts? -tony

ASR 33 For Sale - Fully Restored

by billdeg＠degnanco.com

(I am passing this along for a friend who restores and sells teletypes) "..It has been serviced, tested in local and line mode and is in excellent operating condition. Only the motor gears, belt, oil pad and rubber hammer were replaced to bring it up to like new operating condition. It has an even parity keyboard. This is the nicest 33 I have seen in many years. The only thing that keeps it from being perfect is a few minor nicks on the cover and some scratches on the pedestal. No copyholder is included, but a source for them is available if one is desired. This 33 has a rare lighted lid w/window Teletype option. If this option is not desired, the lid will be replaced with another very nice one. .." Pictures: http://vintagecomputer.net/wayne/Description_and_pics_of_Sept_2001_33.pdf $1200 Please email teletypeparts-at-aol.com if you have any questions.

DEC Floppy drive DS-53A

by cclist＠sydex.com

Does anyone have the specs for the JPN DS-53A half-height 5.25" floppy drive? Apparently it was used on some Digital equipment, as units with DEC branding exist. The web is conflicted--either it's a 360K or a 1.2M drive. I'm wondering if it's just an RX50 clone in a half-height package and SS 96 tpi double-density. Does anyone know for certain? Thanks, Chuck

cleaning and maintenance for an ASR33

by starbase89＠gmail.com

Hello. I have an ASR 33 teletype that I am trying to clean up and make it run well. It does work. I plan to have it hooked up to a PC via a current loop to RS232 adapter and have HeavyMetal feeding it text. It is very dirty. I replaced the ribbon. Basically, here's what I'd like to know: What parts need to be cleaned and/or lubricated? How do I clean out the paper tape punch scrap container? Can I use compressed air to remove dust, or would that cause damage? Thanks much Joe

Interesting email addresses of old...

by tshoppa＠wmata.com

For my first 4 years with E-mail I was only on DECNET/HEPNET. So DECNET style E-mail addresses for me (TDS222 at IOWA and TSHOPPA at FNALF). Later on, some of my BITNET E-mail addresses from the 80's and early 90's are found when I google myself. Some of these were on the same VAXes via BITNET gateways, others were on PRIMOS machines on BITNET, a couple were genuinely on IBM hardware and then later Amdahl hardware. I really struggled with the IBM user interfaces :-). I did use UUCP forwarding on several occasions but I never thought of the bang-path as "my E-mail address". Amazingly enough several of the LISTSERV's that I subscribed to/posted to back in the 80's still exist today in one form or another. Some were surprisingly hard to find but they're still there.

Seattle Retro-Computing Society's monthly meeting Saturday, September 17th, 2011

by glen.slick＠gmail.com

[forwarded on behalf of SRCS] Come one, come all, to the Seattle Retro-Computing Society's monthly meeting, on Saturday, September 17th, 2011! Do you do any of the following with old computers near Seattle? + Use, collect, and/or restore them + Play games on them + Write programs for them + Develop new hardware for them + Help other people do any of the above If your answer was "yes," as I expect it will be if you're reading this near Seattle, then the SRCS is for you! We exist so you can show off your awesome stuff, bounce ideas off of fellow enthusiasts, and be inspired by one another's achievements, plans and aspirations. No idea is too big or too small, and we're not picky about what flavor of vintage machine you prefer! Come on down and tell us about it! The meetings are graciously hosted by the Living Computer Museum, a relatively new organization which is building a computer museum in Seattle's SODO neighborhood. There will be refreshments, a Buy-Sell- Free-Trade table, and enough table space & power to set up anything you may want to show off! For further details, please see our newly improved web page at http://www.seattleretrocomputing.com/ and our mailing list at http://groups.google.com/group/seattle-retrocomp . Hope to see you there! (Please note, we usually meet on the fourth Saturday of each month; we had to move it up a week this month because of schedule conflicts with retrocomputing events in other cities.)

Desoldering (Again)

by robert.jarratt＠ntlworld.com

(resending from a different account, apologies if this is a duplicate) I have a 16-pin IC to desolder and I am struggling. Since I last asked about desoldering I have got a lot better with a de-soldering pump and can now clear the hole in the sense that I see a black hole rather than solder, and I can see daylight through all the holes (but for most of the holes this is only if I angle the board the right way). However, in this case the solder seems to be going all the way through and slightly onto the component side surface where I can't get at it with the pump. I have jiggled the pins to try to break any last bits of solder, but the chip is still very solidly attached. Any advice? Thanks Rob

DECstation 5000/120 bad power supply...

by bdwheele＠indiana.edu

It looks like the power supply to my decstation 5000/120 is shot. The storage expansion, which is connected to the the switched C13 on the power supply, powered up as expected but nothing on the box itself. There was a bit of a smell, but no magic smoke :) So how hard is it to repair a power supply for this? My soldering skills are mediocre at best. Should I bite the bullet and turn it into this monstrosity: http://web.archive.org/web/20041210172801/http://www.xanthos.se/~joachim/DS… Its really not been my week with my DEC equipment.

The motor runs but I can't get it to work. So, I need someone who can get it back into working order; although I won't be hooking it up to a Western Union line (if that is even possible today). I also want to be able to use it as a printer for my laptop. In addition, I have a Swiss NEMA machine (the Swiss update of the German Enigma crypto machine). It has output to a teletypewriter and I would love to see if my TELEX could be hooked up to it. I live in Ojai, CA, which is 36 miles South of Santa Barbara. Thanks, John Fickewirth .."

DEC PWS 500au boot failure

Did the battery leak? I have a VAXStation 2000 which had a leaky battery which did some damage on the system board. (Fortunately, it was not severe and it is now repaired.) Check around the battery and near where the battery is connected to the system board as electrolyte can wick along the leads. Does it beep? I'm not sure about this one but some alphas will emit beep codes, if they fail before being able to access the console and some of the codes may be explained in the manual. Presumably there are some signs of life such as fans running and/or lights lighting? The next step is probably to check that the power supply is producing all the required voltages. Maybe there is a label specifying what they should be :-) Maybe not :-( Regards, Peter Coghlan.

Adding machine repair

by alexeyt＠freeshell.org

I have a pair of Olivetti Underwood 288s (10-key 7 digit input, 8 digit output adding machines), one of which I got from list member Patrick Finnegan a couple of years ago, and one which I found in a local thrift store this summer. Finding the second one inspired me to try to get them working... and I am rather out of my depth. The only electrical part (the AC induction motor that powers the mechanism) works fine in both, but both have other, mechanical issues. I've run them some under electrical power and spent a lot more time slowly turning the mechanism by hand, trying to work out what it's doing. Both have 'sticky digits', i.e. the mechanism that both rotates the type wheels into the correct position during the print part of the cycle and then is added to the accumulator in the accumulate part of the cycle doesn't move freely and thus doesn't print and doesn't accumulate the correct totals. One also has sticky pins in the input register and the other doesn't seem to carry at all and has a sticky 'leading zero suppression' mechanism. First and foremost, the oil in both machines has congealed into a sticky mess. I clearly need to replace it, but I have no idea what to replace it with. I suspect that it's something similar to what's used to lube typewriters, given that they were built by typewriter companies using typewriter-inspired mechanisms? Second, I have no idea how to take them apart correctly. I've successfully gotten the covers off, but I can't even get the ribbon holder/winding assembly off since it's linked to a mechanism that's supposed to lift it to switch from black to red ink, and I can't find a way to safely disengage them... I've also tried to remove the platen cylinder, but the ribbon holder is in the way of the retaining screws. The only other things I can obviously remove at this point are return springs that hold various levers/cams in place, but I can't see how that would help me remove anything behind them, and all of the cams seem to be maually aligned on their axles, held in the correct position by the same screws that would need to be removed to take the axles out. Ease of service does not seem to have been a design goal in these machines :-/ My inability to disassemble them is doubly problematic since parts of the mechanism are buried behind so much other stuff that I can't see what they're doing, and there are parts that I can't seem to get to move using any combination of front panel inputs... there's one bit that I've found a way to reset (subtracting) but not a way to set using normal inputs... and I don't see any way of actuating the ink-color-swithcing mechanism. Does anyone have experience with anything similar that would be able to offer advice? I'd be glad to make photos and my reverse-engineering notes available... They are fascinating machines (the whole accumulator rotates around backwards to subtract!), but I am afraid of damaging them with my clumsy attempts at repair. Since I have two, I guess I can muddle along by trial and error, but I would really love to hear from someone that's worked on a similar device before. Alexey

Old Memorex Terminals

by thomas.gardner＠sbcglobal.net

For the Memorex at 50 events next month we are looking for a few old Memorex or Memorex-Telex terminals from the middle 1980s; in particular, the Model 1377 and/or any Model in the 2000 series. We can pay for packaging and shipping. We would then like to offer them to the Computer History Museum for its permanent collection or we can return them after the events Tom +1 650.941.5324

A herniated disc and a doctor finally convinced me exercise was the only way to not be in constant severe pain). 45 kg is really heavy... /Jonas

Documentation for Clearpoint SNXRAM/12 VME board?

by earl＠baugh.org

Howdy, Anybody happen to have (or know where) I can find documentation on a Clearpoint SNXRAM VME board? I've tried Googling for it, but no luck. I've got one and would like to add it to my Sun 3/110. (which I finally got booting after a lot of work finding all of the bad ram on the motherboard) Wondered if anybody happened to have info, esp. for the configuration jumpers (I can get it to "add" 6MB, but suspect it might be overlapped with the motherboard ram... that, or it has a bad chip or two... [which are sadly soldered on...] ) Want to make sure I've got it set up right before I EVEN BEGIN to think about attempting to debug the chips on it... :-) Earl

What's 6 Feet Tall and Weighs 1,500 Pounds? A Minicomputer

by jblaser＠sisna.com

From today's (August 24) Wall Street Journal front page: http://online.wsj.com/article/SB10001424053111903596904576516552161014410.h… Written as a bit of a puff piece, but interesting nonetheless, given the national reach of the WSJ. It might (though I doubt it) spur a few Wall Street types to take a keener interest in retro gear, making things dearer and harder for us homie hobbyists to acquire. :) Kudo's to Ian (King) and Rich (Alderson), et al. -- Jared

I certainly wouldn't like to take an AR-88 down from an overhead luggage rack, let alone putting it up there, and certainly not having it fall out if something happened... Brrr...

Free: Big CRTs in Chicago

by silent700＠gmail.com

I am moving (locally) in a few weeks. I've just started packing and, with much less success, trying to figure out what doesn't need to move with me. First off the pile are two large, old CRTs: Sun GDM1962B (http://www.monitorworld.com/Monitors/sun/gdm1962b.html) SGI CM2086A3SG The Sun has a 13W3 connector and is probably contemporary to the first Sparcstation line. The SGI has 3 BNCs and the *old* logo, which probably means it went with the Personal Iris era of SGI. That almost makes it collectable to me but...no. No CRTs for me. At least not for machines that can me made to work with an LCD. They're free for pickup if you happen to be in the area (60074.) No way I will ship these. -- jht

TRS-80 Model II Digging

by nathan＠nathanpralle.com

Finally pulled out the TRS-80 Model II tonight with the intention of actually working on it for once (shocker!) and trying to get it operational. It powers up, drive spins, screen comes on, lights glow, etc. Insert any one of about 20 8" floppies that I have that are specifically for the Model Ii and..... Nothing. Well. BOOT ERROR RS, which is translated as, "Disk not in RadioShack format." I'd believe it for one or two, but all of them? It seems unlikely, although I could blame bit-rot perhaps. I'm hoping it has something to do with the hardware instead. Popping it open, the unit powers on and the drive head is dropped to the spinning disk, then lifted, then dropped, then lifted, and the error occurs. I cannot see if the head is close enough to the disk or not (and I have *no* idea of the tolerances anyway) and am not sure how I'd adjust it -- or drive speed, etc. if that's an issue. So, anyone got ideas? There *is* a remote possibility that all the disks I got were wiped either by the previous owner or in some sort of magnetic disaster, but they're well-labeled and came from a working haul, so I have to imagine that they're still good. Or at least, I'm hoping they are. (The bits are damned near visible on these things, after all.) Your ideas and good guesses welcome and very much appreciated. Nathan -- *Nathan E.
