Tek 4052 / Dc300 tapes issues

by shadoooo＠gmail.com

Hello. About the DC300 cassette repair: I have a lot of these cassettes, original from DEC with standalone backups of software for VAX 730 inside. Unfortunately all of them suffer of the "sticky" problem, the tension band attached to the tape, and then broke itself. A replacement of the bands is surely needed, the plastibands maybe could be a good source. The problem of the stickness remains however: how could I detach the tension tape from the magnetic tape without peel off the magnetic substrate? Maybe opening the cassette, adding some lubricant without solvent (silicon oil for example) and leaving it for some days could help? Andrea

Need Timing Generator Coil for a DEC paper tape punch

by michael.99.thompson＠gmail.com

The Timing Generator Coil on the paper tape punch on the PDP-9 at the RICM is open circuit. The current plan is to try to source some really fine magnet wire and rewind the coil. It would save us a lot of time and effort if someone would be willing to donate a replacement coil. Is a PDF version of the maintenance manual for this Royal McBee punch available? -- Michael Thompson

Tek 4052 / Dc300 tapes issues

by jdr_use＠bluewin.ch

So I picked up a pair of Tek 4052, plenty of doc and spares, and some library tapes. Sadly tapes were stored in less that ideal conditions. So I have mouldy tapes, and lots of broken DC300 drive belts. I am ready to ignore the mould, but what about the drivebelts ? Any alternatives to pinching them from still functional cartridges ? Jos

Running DDR really slow, for a microcontroller

Has anybody used a DDR3 part in DLL Disable mode? I'm looking at a Micron MT41J512M4, and the datasheet says that in this mode, the max. clock period is 7800ns. (thats 128,205 Hz) So it looks like you can interface these with microcontroller just fine. Anybody tried this? Randy

Available S-100 PCBs

by LYNCHAJ＠YAHOO.COM

Hi, an update on available S-100 board PCBs Good news!? There are several new and reordered S-100 PCBs available! The S-100 68K CPU boards are almost gone and there is still 1 available. There are 23 of the S-100 IDE V2 reorder PCBs and 3 of the new S-100 bus terminator/prototyping board PCBs. There are 3 of the S-100 LAVA PCBs available. http://s100computers.com/My%20System%20Pages/68000%20Board/68K%20CPU%20Board .htm http://s100computers.com/My%20System%20Pages/IDE%20Board/My%20IDE%20Card.htm http://n8vem-sbc.pbworks.com/w/browse/#view=ViewFolder&param=S-100%20bus%20t erminator http://s100computers.com/My%20System%20Pages/Lava-10%20Board/LAVA-10%20Board .htm The S-100 PCBs cost the same as before ($20 each).? However due to unforeseen extreme price increases in shipping by USPS I am forced to change shipping costs. Shipping in the US will be $3 for a single PCB and $2 for each additional PCB.? Shipping internationally will be $10 for a single PCB and $3 for each additional PCB.? This is for the bare basics USPS first class postage with no tracking or insurance.? The builder assumes all risk of delivery as per usual arrangement. I apologize for the large price increase on shipping but this is out of my hands.? The USPS is in dire financial trouble and is raising prices on shipping.? It affects us all and is most unfortunate.? These boards are provided "at cost" so there is no margin to absorb any shipping price increases.? I have to pass them along. If you would like one or more S-100 PCBs please send a PayPal to LYNCHAJ at YAHOO.COM Thanks and have a nice day! Andrew Lynch PS, if you would like to help out this all-volunteer project please get one or more of the S-100 LAVA PCBs. These PCBs are the oldest ones and them sitting around on a shelf does no one any good. I?d like these to go to a hobbyist who would get some enjoyment from these fun to build and use boards. Thanks in advance. I truly appreciate everyone's support in moving these remaining boards. You make this hobbyist home brew project possible.

ADF/high speed scanner - Toronto area?

I posted this to a local list (Unix Unanimous) but got little response, so am reposting here. --------------------- Anyone have a scanner (some kind of ADF) that I could borrow or use on site or even buy (especially Epson, which I've seen superb results from)? I have a lot of ring binder type pages that I'd like to scan. 300/400 dpi should be adequate. This is just a non-commercial personal retrocomputing project. Toronto area (~ Davenport).

AT&T 3B1 / 7300 UNIX PC parts needed

by classiccmp＠philpem.me.uk

Hi guys, A few of you might be aware of my UNIX PC emulator, FreeBee (also known as 3b1emu) and the issues regarding it not being able to boot UNIX properly... and my complaints about the quality of the PAL equations in the technical reference. Well, an anonymous donor very kindly freight-forwarded a UNIX PC to me. Sadly the original sender didn't pack it very well... The machine was sent unwrapped with only a few foam peanuts in the box. It arrived with a "resealed by USPS" sticker, a "resealed by Parcelforce" sticker and the keyboard hanging out of one edge of the box. Here's what's missing or wrecked -- does anyone have any of the following 3B1 or 7300 parts spare? Keyboard - * Top cover, several broken screw posts in the top cover. These look difficult to re-glue... * F8, HELP UP/DN, NEXT/3, ROLL DOWN/0 and RIGHT CURSOR/. keycaps. Monitor - * Monitor stand (tilt/swivel section) smashed to pieces. Probably need a new lower monitor case from a scrap 3B1 to fix this :( I'd also rather like to find out what sort of connector was used for the power connector at the PSU side - the cable and connector are badly burned (apparently a common problem). On a lighter note, the machine is fairly well specified - with a P5.1 motherboard, two 67MB hard drives (both Miniscribe 3085 units) and some unusual I/O cards. One is probably a modem (three RJ11 sockets), another has a 37-way female D-sub and the third I can't remember off hand. I still need to formulate a plan to power it up - I'd rather not use an ATX PSU, and the original switcher is 115V only. The 20A current requirement on 5V means none of my bench PSUs are suitable... It also wants +12V (which I expected - the HDDs and line drivers need that) and -12V (probably for RS232 and the modem)... Much thinking needed, I dare say... Thanks, -- Phil. classiccmp at philpem.me.uk http://www.philpem.me.uk/

Dr. Alan Wilcox and 68000 S-100 board

by brian＠marstella.net

Hi, everyone. I've been following the S-100 community for quite a while now, especially the newer boards created by Andrew, John, and others. Last year, I was lucky enough to meet with Dr. Wilcox and receive numerous bits of computing history, especially the notes and the 68000 S-100 board that he designed. He was gracious enough to permit me to scan and post the notes, which I've been planning to do and still will accomplish at some point. I have posted photos of the front and back of his 68000 board (wire-wrapped, no less) on my web site http://marstella.net/?p=245. I also have his only copy of the 68000 book he wrote containing all of his errata. I'm planning to get that information compiled first as that book still appears to be very popular on eBay, when a copy shows up. I'll post more as I gather and organize information and will try to post summaries of each journal as there are many of them. There are also numerous schematics and code listings spread across dozens of manila folders. Regards, Brian.

Anyone want some free EISA cards?

by lproven＠gmail.com

During the ongoing clearout, I've found some full-length EISA controller cards. By the look of it, there are some SCSI 2 host adaptors - they have high-density 50-pin connectors on their backplates - and what might be ESDI controllers. I don't own any EISA machines any more and am not expecting to, so if nobody wants these, I will send them to recycling. Free for the cost of postage. Surface post to the USA/Canada/south America would not be /too/ prohibitive. They're currently in London. I've never had any interest in anything on the Vintage Computer boards & I don't think these are worth eBaying, but if anyone wants to disseminate this offer, please feel free - including my email and other contact details in the .sig. -- Liam Proven ?

New Kaypro Success and then Woe

by brain＠jbrain.com

I scored a reasonably good condition KII on eBay last week, which booted but looked like it just needed some CRT adjustment (screen was garbled, but in a small line at center, which suggest a simple pot tweak). Sure enough, got it home, plugged it in, popped the lid, adjusted the pot, and intro text. Used teledisk to make a boot disk, and the machine booted! Since I had it open and I was trying to check on the drives in the 4, I disconnected the internal drives in the II and connected a K4 drive. On power on, the drive did not even spin up, and so I pulled another Kaypro to test. Does the Tandon use different voltages? Now, tonight, I boot the unit, and the drives spin up but the activity LEDs won't light up on init, and it obviously won't boot. A spare tandon SSDD behaves the same. It appears the drive logic on the main PCB is not operational now, though I can't imagine plugging a DSDD from a K4 would mess things up that much. Any ideas on where to start looking?

[ebay ad] two Tube/Valve analogue computers Donner 3000

by Arno_1983＠gmx.de

Hello, please excuse this little plug for gear on ebay from a friend of mine. He just told me he put what pretty much amounts to two Systron Donner analogue computers from 1954 on ebay and asked me to spread the word where I think it might be heard; I'm not involved with the transaction in any other way. http://www.ebay.de/itm/251273118755 Computer Module, Initial Condition Modul and a custom Function Generator module are present twice, Cyclic Reset Generator just once. Several patch panels and potentiometer modules, documentation and schematics included, but no cables. Will _NOT_ work "out of the box", restoration required. Freight shipping from or pickup in Northern Germany. He states the gear was shown in the German computer documentation "WDR Computernacht" as opener on the 8th episode "Artificial Intelligence". Thanks for putting up with the occasional ad. So long, Arno

OS/2 on hardware other than '286 or '386 processors

by rob＠bitscience.ca

It didn't happen, at least not at IBM or Microsoft during the Joint Development Agreement era. It would have been physically impossible. After IBM had OS/2 to itself, all sorts of strange things went on. So, I can't completely discount a port after that point. I would be extraordinarily surprised if IBM had targeted DEC hardware, though. But up until "the divorce", I can unequivocally state that no such thing happened. - Rob Ferguson (Microsoft 1986-1996 and other times)

Anyone have a IBM Model 25-286 Riser card?

by raifield＠gmail.com

I had the bright idea of swapping out a Model 25 board (8086) with a Model 30-286 board, thinking that the boards were exactly the same. They are, actually, but the Model 30 board comes with a three-slot ISA riser, which does not fit in the Model 25 case. Apparently I need the Model 25-286 two-slot riser. I don't want to try plugging the original 8-bit Model 25 riser in, I fear it will somehow fry the board. Does anyone have a riser card they're willing to part with, or know the IBM part number I need to be looking for?
