Updates to the Little Orphan Tomy Tutor site

by spectre＠floodgap.com

Updates have (finally) been completed to the Little Orphan Tomy Tutor page. This page is dedicated to the Tomy Tutor, an unusual brother of the Texas Instruments 99/4A, and its Japanese and UK relatives, featuring pictures, scans, documentation, programming information, cartridge lists, hardware specifications and more. The URL: http://www.floodgap.com/retrobits/tomy/ Updates this time around: * A completely new and separate section for the Tomy Pyuuta series, with complete photographs of the inside and out of the rare Japanese Pyuuta and the even rarer Pyuuta Mk II, and screen shots and manual scans where available. (Pyuuta Jr. section coming soon when I land one of them. ^^) * Redone photographs of the main unit and motherboard, including how to take apart the unit and identify major components, as well as new photographs of packaging, ad copy and peripherals. * Additional screenshots and cartridges in the Incomplete Catalogue, including the "3-D" series. * GPL LIVES! Raphael Nabet provides new information that an unusual variant of GPL does indeed lurk within the Tomy (rats!) on the TI vs. Tomy section, and also contributes large amounts of information to update the Memory Map. * Hardware page updated with new information about Tutor hardware mappings and ROM banking strategies. * Various custodial updates. Please let me know about any questions or inaccuracies. Have fun! -- ---------------------------------- personal: http://www.armory.com/~spectre/ -- Cameron Kaiser, Floodgap Systems Ltd * So.

Intellec-mds 800

by melamy＠earthlink.net

actually software for it would not be a problem if I can ever get my hands on a MDS800 or MDS230 series II. I have all the ISIS software that Intel produced for the machines, BUT I can't duplicate the disks yet. I am working on a MDS225 that I have - part here in Virginia and the keyboard and display subsystems back in Washington state. I still have a standing request to anyone that has one of these machines that would like to part with it for cash or other items.

Rust on tape heads

by root＠parse.com

I've noticed a few spots of rust on some TU55 tape heads that I have. I'm wondering what I should do about it in the short term -- I've had an idea of putting something on the heads and then cleaning it off later, like oil or vaseline or... ? Any suggestions? Is there anything I can do with the heads later to clean the rust off? Are they totally hosed, or will they still work? This is on my "todo list" as far as restoration goes, just haven't gotten to it yet, but wanted to prevent any further damage if possible...

DEC Educational Guides

by dj.taylor＠starpower.net

Back in 1984 I journeyed to Lexington, Mass and took a course at the DEC facility in Bedford (I think). It was a 2 or 3 day RT11 course, and was quite good. I remember bringing home a thick green book that was the guide for the student, I don't have it anymore; does anyone have one of these? The course I took was for RT11 V4, I wonder if there was a V5 course. Anyone take one of those DEC on site courses? I've never seen this type of DEC documentation offered for sale on ebay or anywhere. Maybe just rare? Doug

HP2100A available (Bristol, UK)

by classiccmp＠hexamon.org

Free to the first person who can collect it: I have an HP 2100A looking for a new home; this system doesn't come with any peripherals, it's just the system unit. I have no idea what the modules are in this system, but at least one of them appears to be a magnetic core store. I've never switched this system on, so I don't know what condition it is in - I'd certainly recommend testing the power supply offline before use. Since I have no software for this, it's most likely to be useful to someone who has the software and peripherals already. The date shown on the chips would point to a manufacture date arond 1975. This system in in Bristol UK, it's heavy and fragile and therefore I would prefer not to ship it. Priority will be given to anyone who can collect, but if there are none such then I am prepared to ship it provided the taker covers my packaging and shipping costs plus any import duties.

My sister's ISP just started doing that (cablevision... probably the same NY ISP you are referring to). She now has to have two different account setups. One for when she is home and wants to send email, and one for when she is traveling and wants to send email. Major PITA if you ask me, and seriously overkill for the problem at hand (but fairly typical of the cablevision attitude towards customers). At least if you are going to block port 25, do it like AOL. Capture the traffic and reroute it thru your own mail server. That way users can stay blissfully unaware of the block, and continue to use one mail setup for all occasions. -chris <http://www.mythtech.net>

Does the name 'Ed Kelleher' ring any bells?

by kyrrin＠bluefeathertech.com

Fellow computer tinkerers, I had a recent E-mail exchange with a fellow named Ed Kelleher, apparently the president of a company called 'Macro-Inc.com.' They appear to sell overpriced (to my eyes, anyway) DEC systems and parts. What had happened was that I had found, in my mail server logs, entries which showed that Mr. Kelleher had tried to send me something, only to have it bounced repeatedly due to the fact that I'm currently blocking traffic from the biz.rr.com domain (this last due to RR.Com's utter lack of response to ongoing spam, port probes, and other abuse coming from their network). I sent him a polite note advising him of what I'd found, and asking him to please re-send the message to my backup address, which is not spam-filtered in any way that I know of. It worked -- sort of. I got back a very terse -- I would actually call it rude -- reply to the effect that he'd tried to send whatever he was sending five times, with and without attachments, and had finally given up. In his words "I don't care to send it again. Stupid policy of yours." This tells me right away that he has absolutely no concept of what I, as a self-hosted SysAdmin, go through each and every DAY, trying to protect my network effectively against outside abuse. That point aside, I sent back another polite request, saying that I'm sorry he felt that way, and asking that he please not blame me for doing what I felt necessary to protect my tiny corner of the Internet. I also asked him if he would consider at least telling me what it was he was trying to send. No response yet, of course. I'm not sure I'll ever see one. Based on what I saw of his company's web site, though, I suspect that what he had to send may have been of minimal value in any case (possibly even spam). Has anyone on the list had any contact with this person or his company? The vast majority of people that I've asked to re-send their original message have no problem with it, and are fully understanding of why their initial attempts might have been blocked. What's gotten into this fellow that he can't seem to understand the view from my side, especially considering that he sells (and presumably works with) computer goodies? Insights and opinions welcomed. Thanks much. -=-=-=-=-=-=-=-=-=-=-=- Bruce Lane, Owner & Head Hardware Heavy, Blue Feather Technologies -- http://www.bluefeathertech.com kyrrin (at) bluefeathertech do/t c=o=m "If Salvador Dali had owned a computer, would it have been equipped with surreal ports?"

CD Shredder

by mmcfadden＠cmh.edu

I was down at the computer surplus store and found a shredder in the metal recycling bin. The case and covers were missing. I purchased it. It has a chain drive, larger than a bike chain, large motor, and will reverse if it stalls. Lots of nice whirring bare blades/disks. It will handle about a 1/2 inch thick pile of paper at one time. CD's don't even slow it down. My wife has come home to find me sitting on the floor shredding old checks and tax returns. Kind of therapeutic to here the whir and watch paper turned into strips. I then feed it in again and out comes chips of paper. Paper clips are OK, only has a problem with paper clamps. Kind of dangerous, but what fun is a safe shredder. Probably needs dual interlocks so that I must have both hands on them to prevent me shredding my fingers. Mike

Cleaning up yellowed/grubby plastic?

by philpem＠dsl.pipex.com

Hi, Does anyone happen to know of a trick to remove (or lessen the effect of) the yellowing that tends to happen to lighter-coloured plastics? I've got a few monitors here that are pretty bad - the yellowing I can put up with, but the difference between the non-yellowed areas and the yellowed areas shows up like a sore thumb. Is this just one of those things that happens to plastics that's best ignored?

S.F. Bay Area -- PDP-11 HW available -- Disks and Tape for 11/44

by wmaddox＠pacbell.net

I was up at Mike Quinn's on Saturday, and inquired about classic computers. After mentioning the PDP-11 by name, the guy there (Maurice) pointed me to an 11/44 he had in the back. The racks were already spoken for, and the contents had been pulled out and were sitting face-down on the floor. There was an 11/44 CPU, two RA-81 disk drives, and a 9-track tape drive, a TU-80 or TU-81, I believe. He was willing to let it go pretty cheap, $100 for the CPU and RA-81s, or $50 for the CPU. He thought the motors in the tape drive would sell for $25 each, so he wanted at least $50 for that. Seeing the lack of respect this poor old machine was getting (dumped on the floor to salvage the rack), and having some space in my trunk, I snapped up the CPU without much further thought. I figure a collector should have a shot at those drives before Quinn's sells them to a scrapper or someone who wants to strip them for parts. I don't have the space for them, nor enough interest in the later 11's to justify renting any more on their account. I could possibly be talked out of the CPU. I'd certainly take a smaller Q-bus '11 in trade. Heck, a convincing promise of a good home with some happy peripherals to talk to and reimbursement of the $50 I spent would probably do. :) --Bill

logic rack?

by rigdonj＠cfl.rr.com

I got a call from a scrap place today and I made a quick trip out to see what they had before the hurricane hits (it's due to cross DIRECTLY over the place's location so I don't expect the stuff to be there come Sunday AM since most of the stuff is out in the open). Got some DEC core memory so the trip was worth it. One of the things that I found was a "Logic Rack" made by (somebody) Research & (something). Sorry to be vague about the name but I was in a hell of a rush. Anyway it said that they were a division of XEBEC. The rack was ABOUT 8" or 10" thick and ABOUT 32" wide and ABOUT seven foot tall and had HUNDREDS of small circuit cards that plugged into it. None of the ones that I saw had ICs, just glass diodes, trqnsistors and resistors. The cards are 4" long and 2 3/16" wide with a 16 position CINCH contact on one end. The transistors that I looked at were all date coded 1969 but I saw what looked like it might have been a date on the rack that said 1973. Anybody know what this is? Joe

classiccmp mailserver issue

by jwest＠classiccmp.org

The classiccmp server coughed last night, apparently around 2am. I didn't notice it till about 8am, and couldn't get to it to work on it till about 10:30am. It would appear that S.M.A.R.T triggered again, claiming the 160gb drive is failing. I'm not sure I believe it, but really don't want to take the chance either. I may well finally have to go shopping for a 160+gb drive. Anyways, wanted to let folks know there was an outtage in that time frame, if you didn't notice it already :) Jay West

I would guess that the pot was to drop the voltage to be within this range. If one was to adjust the pot, there should be a range of adjustment that the speed ( with load ) was relatively constant. One would adjust the pot to be safely within this span. Dwight

iris 3030 on ebay

by aek＠spies.com

1) Why do the IRISes look that different on their back sides? -- Looks like they were trying to increase airflow. The 24xx's were solid black on the back, with only the upper area above the I/O panels for air exit. Most of the boxes that I remember had the I/O expansion panel on the left like the 3030 in the auction.

rodent nests

by rich_bramante＠yahoo.com

So the good news is I've stumbled upon a Frankin Ace 1000 and a TRS-80 Model I with EI unit, 2 machines which I've been looking to acquire. Better yet, both are FREE! The bad news: some sort of rodent(s) decided that the shells would make nice homes and built nests in them. I popped open tha Ace, haven't had the heart to check out the inside of the EI yet. Most of what was in the Ace was bedding and shells from eaten nuts. These came out easy enough. All wiring seems to be intact and uneaten (the back of the case did have its card slots widened by rodent teeth however -- not a big deal). There wasn't really any droppings as I imagined there would be, but there is a brown film that is on much of the motherboard. What is this (urine, oils from their fur, some other sort of bodily excretion) and is there anyway to clean these systems and try to recover them? __________________________________ Do you Yahoo!?

Manual for Intellec 8 ?

by jack.rubin＠ameritech.net

Anybody have a spare copy of the "MCS-8 8008 Users Manual", Rev 4 (November, 1973) or later (though Rev 4 is the latest I've seen)? Al has Rev 2 at bitsavers and I have a copy of Rev 3 (March,1973), but the earlier manuals only deal with the SIM-8; Rev 4 introduces the Intellec 8. Of course I'd love to find the actual manual, but a good copy would be greatly appreciated, as would any other info on the 8008-based Intellec 8. I've do have a fair amount of info on the 8080-based Intellec 8I which I will be scanning and posting at bitsavers or Howard Harte's archive. - Jack Rubin Wilmette, Illinois USA

11/23 or 11/03 picture of DEC/PDP logo

by waisun.chia＠hp.com

Hmmm...my BA11-N (11/03L) was resprayed evidently as there are paint oversprays to the control panel area (the toggle switches), but I didn't know that the BA11-N front was actually in a single plain color.. I know that the BA11-M (11/03) has a nice DEC/PDP logo with color, and the BA11-S (11/23) also, so I assumed that the BA11-N has too.. Heck, and I thought using the DEC maroon for the background and white for the DEC bricks and PDP logo.. /wai-sun

SIMH & root

by dholland＠woh.rr.com

Speaking of SIMH.. SIMH requires root privileges to do its networking (at least on most of its unix host OS's), understandably, but I'm not happy with it... So I've hacked up some code changes that'll let me change the UID/GID & chroot() SIMH is running on from the SIMH console. The idea is.. attach (network devs) attach (other root owned devs) set priv root=/some/chroot/jail gid=-1 uid=-1 (continue configuring) Anyways, my question is, does anyone else think this would even vaguely be useful? If so, I'll mail the patches into Bob Supnik, if not, I'll not waste my (or anyone elses) time. I figure there out to be at least one or two other SIMH users on this list. :) The "why" of it all.. I may have need of putting up a internet facing VAX/VMS "box" in the near future, and not wanting the heat & power issues of real hardware (yes, its hot in my "computer closet" :-( ) I thought a virtual VAX on my Linux firewall would do. I'm less concerned about the 'VAX' being hacked than I am about the firewall. (Yes, I know theoretically, its impossible for the SIMH environment to affect the firewall host OS directly, save possibly via networking, but I'm also paranoid. :-> ) /me slinks back under his rock, and awaits the snickering..

eBay madness

by ghldbrd＠ccp.com

Yes, notice the number of bids. Somebody thinks he's got something higly desireable, but doesn't. I've found e-Bay, or ePay, or eGreed to be quite inflationary to sane pricing thanks to too many people with too much time and money on their hands. That coupled with 'sniping', makes eBay to me a last resort, if I can't find something elsewhere. The feeding frenzy at the end, or sniping, is now done by software that submit your bid with seconds to spare, eliminating counter bids. People are using computers to beat the eBay computers. My friend suggested that the incremental bidding be changed to whatever the MAXIMUM bid is placed. If the item is at $10 and you place a bid for $100, the bid would then become $100, not $11.00. That would eliminate a lot of counter bidding, and shills that bid up just to feel out your maximum bid. Personally I think keeping the bidding secret until the auction is over, would keep honest people honest. No one scheme would be fair to everyone though. I'll stick to swap meets, and other face-to-face deals, as I'll have less competition. Everything is worthless until someone wants it and puts some dinero down to prove it. I don't need some rich kid playing games behind me when I'm dealing with someone one-on-one. On the other side of the coin, it is hilariously laughable to see what some people pay for very common items. Caveat Emptor. Gary Hildebrand St. Joseph, MO

On those BA11-N (and similar) boxes, the whole front is the same colour, logo, PDP-11 designation, and all. It's called DEC Gray #<somenumber>. The only ones that are any different are later ones (eg some BA11-S boxes) for some 11/23-Plus and 11/73 systems, which are still all sprayed the same colour, but then have a black plastic sticker added with the model number. Nothing is supposed to be masked out on any of them. -- Pete Peter Turnbull Network Manager University of York

Old games for sale, cheap

by aw288＠osfn.org

My brother gave me a box of his old DOS games, and told me to get rid of them however I saw fit. CCTALK, here they come! Anyway, I have 20-ish pound box full of early 1990s DOS games (maybe some Windows, too) for the PeeCee. Let's see, we have Ultima 4, Pirates, various AD&D games, Roger Wilco, Gunship 2000, Tornado, Wooden Ships& Iron Men, and probably a few I missed. Knowing my brother, everything original to the games is there (yes, these are real, store-bought, non-pirated originals). One money gets the whole pile - I don't want to sell individual games. Cheap. Make a stupid offer over shipping. William Donzelli aw288(a)osfn.org

archiving Heath H8/H89 hard-sectored disks

by ddl-cctech＠danlan.com

I've come up with a way to read Heath hard-sectored disks with a 1797-style controller (with some modifications). I've now archived all of my old disks with only one unrecoverable error in an unused sector (not bad for media that is approaching 30 years in age). I do seem to have run through *drives* at an alarming rate, though I hope that the cleaning disks I have on order will restore some of them. Is anyone interested in: -Technical details (the method should work for many non-standard FM formats)? -Having me read any H8 disks? -Any distribution images that I might have?

DATA I/O Unisite Manual

by Steven_R_Hutchins＠Raytheon.com

Bruce, I have read a number of old post's on Data-IO...and they seem to be right in line with what you state on their tech support on their products. I called a different sales engineer and he was quite nervous when I mentioned the user's guide listed the maintenance manual. He finally fessed up and said they used to have a service manual available( which also came with diagnostic software ) but they were having legal issues with ICs not being programmed right after UNISITEs were repaired by other than "their certified factory". He proceeded to tell me that to become a certified repair point for DATA IO , a training and certification could be arranged ...for a price. I then asked "do you have a list of the service centers in the US? " His response was" there are none besides the one in Redmond,WA (Data-IOs main office), the cost to become certified is very expensive". He is sending me a quote. Please send me ...offline... a price for the waveform generator board.

They've gotten excessively greedy in recent times, and they want EVERYthing to come in for service. How do I know they're shining you on? Because I have a maintenance manual for the earlier Unisites. I picked it up during a scrounge run in the Bay Area several years ago. If you want to try and bamboozle them, ask about the availability of part number 972-0014-003. It may have been superseded by a later edition. >I am getting "waveform Generator Failure" upon bootup.

Best keyboards you've used ever!

by m.wickens＠rhodium-consulting.com

OK, this one is bound to get a few responses: List the best keyboards you have ever used. You might like the feel, number of function keys, layout (let's not forget Dvorak or more esoteric designs) or pure keyboard<->computer love (you might really get off on Vaxen). My list is something like: 1. IBM Model M (original buckle-spring technology, still standing the test of time) 2. Unicomp PC 5250 (two rows of function keys at the top upto F24 and a set of 10 on the left, can be bought new and 'broken in') 3. DEC LK421 (not-often-seen cut-size Unix programmers DEC keyboard) 4. Wyse WY-40 (very nice positive feel with sturdy base) 5. Early Chiconi PC keyboards (hopelessly rattly and cheap but engaging 'click' and quick to type on none-the-less) 6. My college used to have a computer room full of terminals, possibly Adds, which had a very nice short travel and positive click keyboard). 7. ZX81 (simply because it was my first computer). 8. Cherry high end keyboards. 9. DEC keyboards with a 'Do' and 'Help' key. 10. SUN keyboards with 'Cut', 'Copy' and 'Paste' keys. I'm a great fan of dedicated keys, and function keys on the left. Whoever decided to put the out of reach at the top of the keyboard needs their head examining! There must have been some stonking keyboards attached to more vintage hardware. I'd love to know about them (if that doesn't sound a bit weird!). Mark. -- Mark Wickens Rhodium Consulting Ltd

New toys: 1944 IBM !!! Warning OT

by rigdonj＠cfl.rr.com

The past couple of weeks weren't a complete lose. On my trip out of town to find a generator I finally manage to pick up something that I've had my eye on for quite a while. A 1944 made IBM (wait for it!) Carbine! Yeap, a gun! A US model M1 .30 caliber carbine. This was made at IBM's #4 plant in Poughkeepsie, New York. According to the SN it was made between January and March of 1944 and this one appears to be 99% original. The only thing that appears to be non-original is the butt plate. All the other parts are the right style and markings for the period/manufacturer. This one even has orignal IBM manufacturered barrel and reciever (many were made under sub-contract by Auto Ordanance and are of inferior quality). The stock and handguard are interesting, they're marked BR-B (made for IBM by Milton Bradley!!!). Also picked up a mint LOW sn (~7000) Inland M1 ( made 1942!!) and a mint Rockola M1. (Rockola manufactured juke boxs prior and subsequent to WW II). I working on picking up a couple more including one made by National Postal Meter and one made by UN-Quality and, with some luck, an ULTRA RARE Irwin-Pederson. Wish me luck! Joe
