TIl308/9 is a latch, dekoder+driver and led-bar display, and has BCD-inputs for data to be displayed. 306 and 308 are identical in its display-dimensions and aparance, the function differs however. To use a TIL 308 as a replacement for a 306 you will need to add externalley somewhere a 7490 decade-counter between the original circuit and the TIL308. I have a few TIL308 available, if this rework is feasable to you. TIl310/1 is a latch, dekoder+driver and led-pixel display, and has BCD-inputs for data to be displayed. Thisone also needs an external 7490 counter in your usage, on top of that, the display has a different appearance. Someone else could have those for you. So, choose the alternative that best suits you, I would continue to search for the original TIL306, or change the whole display to something else althogether. HTH Frank Arnold

I don't know if you can still get them -- I expect you can -- but I can tell you that the ribbon for a Juki 6100 is an IBM 82 compatible multistrike or single-strike ribbon cassette, same as is used on an IBM Selectric II. I used to use multistrike carbon, but you could also get multistrike fabric and single-strike carbon. Fabric, however, tends to clog the character petals after a while.

need some help....

by archivesoftware＠celebritydirect.net

Hello ~ I was a long-time member of this list, and am a long time collector of classic computers. I've been away from most internet forums and collecting computers in general for several years, but am finally getting back into it. Want to say hello to those that I used to gather so much information from... and hello to the many new acquaintances I look forward to visiting with. Today I was in a "flea market" browsing a pretty good collection of classic game consoles and coimputers, and discovered something I had never seen before. It was a cream-colored unit, with an integrated keyboard and monitor. Size could be considered small.... probably half the size of a TRS-80 model 4... or smaller. No disk drives were present. I believe it was called a Scoutset ??? I also think it was made by Temat and had a model # of HE 415-B . I could be wrong on all of that information, however... but it was something similar. I have a sneaking suspicion this is some type of early word processor, but am unsure. Has anyone seen this before, or have any information on it? Would it be worth picking up? Thank you!

NEXTSTEP 3.3 availability?

by sunderwo＠knox.edu

I have been working on getting a NeXT slab that came into my possession into working order since last summer, but have been unable to find a copy of NEXTSTEP to get installed on the system other than the copies Black Hole sells. Black Hole isn't an option for me - I don't think I'll have a spare US$300 laying around for at least a few more years. So does anyone know of a place where I could find a copy of the operating system? Original CD's would be nice, but I would be happy with ISO's, too.

Re.: Computers stored in barn; questions answered

by cmurray＠eagle.ca

R. D. Davis wrote: Are these stored in an area where the temperature doesn't get too cold, e.g., where there are a lot of 4-legged space heaters :-), or in a part of the barn where temperatures vary more? How do you prevent damage to the systems from rodents, dampness, birds and spiders, etc.? Hopefully these systems aren't stored near any cedar shavings used for stall bedding, as the fumes from the plicatic (sp?) acid in the cedar can damage any copper used in circuit boards, etc. Does anyone know if the abietic acid in pine shavings/dust causes similar problems? R. D. - I don't use cedar or pine shavings, just plain wheat straw. The temperature varies across the year. The computers are in wooden boxes, not cedar or pine, and the inside is covered with a black plastic that rodents don't chew on. They have been in the barn since the summer of 1987. I think they're all intact. Have to see this summer. Murray--

Acetone container swelling; safe to keep?

On Jan 5, 15:45, quapla(a)xs4all.nl wrote: > Use a plastic or a glass bottle. If there is a sparc next time you open it > it may fry your eyebrows and/or hair!. NOT plastic. Acetone, MEK, toluene, and many other organic solvents are sometimes supplied in 1-litre pastic containers but should not be kept in plastic for long-term storage. Even polythene bottles will be damaged in the long term -- they go brittle as the plasticisers are leached out. Such things are normally kept in glass bottles for small quantities, say up to 500ml, or metal tins for a litre or more. >On Jan 5, 10:08, R. D.

It should be kept cool (no more than 68deg F). If it's reasonably pure acetone, I can't think of any reaction it should have with steel or tin, so I guess what you're noticing is evaporation causing a slight pressure buildup in the can. Unless it's contaminated -- it doesn't co-exist well with some other solvents (such as chloroform) and moderately strong oxidising agents, or some catalysts (including some forms of carbon). If it's rusting, then you should probably replace the can before it becomes weak enough to leak. -- Pete Peter Turnbull Network Manager University of York

I squirreled away a lot of parts over the years but found that many of them were damaged due to the foam. Fortunately I've get some pretty good scrap sources and I've been finding lots of military grade cards with socketed ICs in the last couple of years so I've been picking them up and pulling the ICs and storing them in parts cabinets. I've amassed a huge stock in just the last year. I was also lucky last year and picked up a good number of parts cabinets that have all the drawers made out of anti-static material. I had been keeping the parts in anti-static foam for AS protestion but now I don't have to. .Thankfully, the TIL311s and >most of the other chips that came in the same batch of parts didn't have >the same problem, though their leads had to be cleaned. I have a fair number of 308 and 311 displays that I've pulled from cards and the local surplus place has plenty of them but the 306/307s seem to be scarce. Joe > >-Toth >

A bit more about me...

by cmurray＠eagle.ca

Hi all, Sorry about the short intro. A bit more: I' a computer teacher; been in the business since 1970 when i learned COBOL programming in Toronto. I earned a BA and BEd and taught ESL in Africa and Asia. My first computer was CompuPro and the Intercept Jr. 6100. Sorry to say they're no longer active as they're in storage in the barn. I raise horses. The computer I still use from vintage era is the Coleco ADAM. Us Adamites keep are favorite machine running despite its early orphan status. I now have an 800 Mhz. Celeron machine. I wrote a book called "A Historical Research Guide to the Microcomputer" which covers the 4/8 bit era as a supplementary paper for my PhD. I try to follow what's happening out there but I'm afraid I have limited time. Too busy!!! A great excuse... Murray--

OS/2 manuals

by cb＠mythtech.net

Is there any interest or value in OS/2 manuals? I have a few OS/2 boxes, and I am pretty sure the software is MIA (never had it, I pulled the stuff from a dumpster long ago). I have decided I don't want to continue to take up the shelf space, so I am trying to find out if there is any interest in these kinds of things or should I just send them back to the dumpster. I don't want to go thru the effort of pulling the stuff out and listing it if there is no interest (the last few items I've offered no one wanted, guess I really DO just have junk). I don't currently know what manuals, or to what versions of OS/2 they go (that is the step I am trying to avoid if there is no interest... I just don't feel like having yet another pile of crap under my desk until I get takers or get sick of waiting). And of course, I would LOVE to find out that OS/2 manuals are worth money... saving for a house when on an already strained budget is a bitch! -chris <http://www.mythtech.net>

It's not particularly toxic, nor particularly dangerous -- very roughly on a par with iso-propyl alcohol, and less dangerous than some solvents that have been mentioned on this list for use on plastics. It's used industrially to "weld" ABS and PVC, as a cleaner in the printing industry, as a degreasing agent, to clean equipment used for plastic foam (including cans of the expanding urethane foam filler used in the building industry), and as a constituent of some plastic glues. It will dissolve most ink and some paints. Like IPA, acetone (nail varnish remover), methylated sprit, etc, it's fairly flammable. It will attack a lot of plastics, but not most epoxies (once properly cured) or "waxy" plastics like polythene. The effect on potting compund will depend on the compound, but it will make some types of RTV (Room Temperature Vulcanising compound) "silicone" swell and eventually make some types crumbly. BTW, the acetic acid given off by curing RTV is rated as 10-50 times more toxic than MEK :-) -- Pete Peter Turnbull Network Manager University of York

Not all parallel ports are created equal. Many are bi-directional though. There are about 3 different flavors. As I recall, I connected the parallel data out to the data lines and ran the strobe to one of the status input lines. There is a start and stop signal that uses to start and stop the tape as well. I can give you a copy of my code. There is a web page, http://www.lvr.com/parport.htm , that has several links to parallel port stuff. Since you are now at the hardware level and on a roll, this is a good place to look. I don't recall if the two drives that you loaned me were parallel or serial outs. I think one was a parallel though.

ADMIN: Coming Updates, Question

by jss＠subatomix.com

If you're in a hurry, skip to the request at the end. Good news! The travesty that was my first attempt at a new web site for ClassicCmp.org has only a few days' worth of life still left in it. We've been long overdue a web site that doesn't (completely) suck, and I intend to provide one as soon as possible. I am finished with college and have become comfortable with my new job, so I now have adequate time to make ClassicCmp a better tool for its members and for the world's classic computer enthusiasts in general. The first stage will be a small set of static documents which will provide a *consistent* view of the site's current content: mailing list info, mail archives, and the FAQ. There will be no mention of anything under construction. Documents will be simple, nearly text-only, XHTML-compliant, and lynx-compliant. Expect this to be up soon. I have written the first half of the spam-defense mechanism we discussed several weeks ago. This half isn't the CGI program I talked about, but instead the processor that replaces email addresses in an HTML document with links to that CGI program. Due to popular demand, the email address info encoded in the links is encrypted by two iterations of DES. I am currently investigating human-verification methods to be used in the CGI program. Expect the archives to be spam-proofed soon. Thanks to Tothwolf the packrat, the missing months of the old list archives have been recovered. Expect them to be up soon, as soon as I decide whether to keep Pipermail or switch to Hypermail (what we used to use) for message archiving. I'm leaning toward Hypermail. Once these things are done and a decent web site is in place, I will look at developing a much more complex, second-stage site, with a file archive, link database, and some degree of dynamicity via PHP or similar. If you have a suggestion, please let me know via private email. By the way, we now have exactly 720 subscribers. I would also like to hear (private email please) from subscribers with comments for or against the current two-list system. Defense of the system is welcome, as are ideas for better ways of doing it. Is it necessary? Should we go back to one list? Should we have more than two lists? Something else? I want _your_ opinion! -- Jeffrey Sharp ClassicCmp List Admin (during Jay's extended break)

DIY Equipment Racks

by rdd＠rddavis.org

While thinking about racks to use for mounting my PDP-11/44 components, as well as other equipment from test equipment to audio and synth equipment, something just occured to me: why bother with hunting down steel racks when some 2x4s and lag bolts may suffice just as well? I was thinking that one can just run 2x4s from the basement floor up to the heavy wooden rafters, attach them to the rafters, and then add horizontal supports at the bottom to space the vertical 2x4s apart properly. Any thoughts on this? I guess the museum-type equipment purists won't like the idea, but it would be a cheap and functional solution for many of us. :-) Has anyone else here tried this? Lastly, has anyone on this list tried retrofitting non-rack-mount equipment into racks? E.g., welding (or "JB Weld"ing) rack-mount tabs onto systems like PCs and Kaypros, as well as making rack-mountable shelves to hold the Macintoshes, etc.? Just trying to think of ways to save space. Stacking system on top of system, helter skelter, as systems are added, tends to result in rather annoying, space hogging, piles of systems after a while, making some systems difficult to get to at times. -- Copyright (C) 2002 R.

Z8000-Fan

by dwightk.elvey＠amd.com

Hi You need to look a little more. You should find other files that may be named incorrectly as *.z8k. Some of these are actually source files and not executables. Most of the assembly source were called *.8kn. Also, many of the files have some garble at there ends. This was because of the extraction process. If you look at them carefully, you'll see that the text starts to repeat it self at some point. Just delete the repeated text to the end. I may have these files in PC file format after they have been cleaned up. I have gone through the process of starting with the source files for the BIOS and actually creating a new BIOS. I was careful to make sure that it ended up matching the original release image. In anycase, with new BIOS code, I should be able to build another new image. This would be much easier than starting from scratch. When you get done, you'd be able to use the C compiler and assembler that came with this release. I'll go back and see, just which files I used so that you can use the matching ones. There were several different source pieces to hunt through. Some of them were older versions. The 1.1 stuff is actually the most current. The other revs seem to be pre-release stuff.

First, you don't have to cross compile CPM-8000. There already is a CPM-8000. Recently, source and release code was found for this and, working with Chris Groessle, we've managed to bring it up on our Olivetti M20's.

Some old computer systemsof interest

by gmanuel＠gmconsulting.net

Hi Everyone, I have a couple of old systems some of you might be interested in. The first one is a Vector. This is an all in on unit running CPM as the OS. I only have the system for this one. The second is an old Commodore SX-64. For those who don't know it, it is a small portable Commodore 64. It had a small (maybe 5" diagonal) color crt and 5 1/4" disk drive internal. I have many additional peripherals for it including additional 5 1/4" drive, 20MB HD, Memory expansion model (256k), mouse, GEOS OS, HearSay 2000 (speech recognition and speech module) and lots of software. It is in 100% working condition and has been well cared for. If you have any questions about these or other systems please feel free to ask. Greg Manuel
