I have a similar device - two actually. The first one I got for free or nearly free, with a Polaroid camera, and no control panel. The second cost under $100 and had the control panel and a 35mm camera, so between the two, I have one useful unit. The Polaroid film in question was sold for medical uses, so was quite expensive even 20 years ago when one could buy it off the shelf ($50-$70 per cassette, I was told). Like your "Videoprinter 4", mine has a mono CRT and a color wheel. AFAIK, it does *4* exposures - R, G, B, and "contrast" (no filter). It takes in an EGA signal or NTSC video, and has onboard memory for frame capture of live video. I've done some sample image grabbing >from a movie on laserdisc, and for practical uses, I use to make title slides with it, back when we used 35mm slide projectors for presentations (I produced the slide content on an Amiga since that was the easiest thing to use that I had on hand). Back when slide houses charged several dollars each for presentation graphics, this was a moderate-quality way of doing my own interstitials for slide shows for the cost of one roll of ordinary 35mm slide film ($4-$5 for a roll of Fuji E-6 ASA 100 film, $7-$8 for processing and mounting). I haven't used it in years, but it was great 15+ years ago when I first got it. -ethan

But I've always wondered (and this may be a silly question): if a controller in a 4.7MHz PC can handle the data flow, why would it be so difficult to basically just connect another (pseudo-)HDC to the target HDC instead of a drive, i.e. effectively connecting two HDCs together back to back? Host MFM HDC || || Data/Control bus || || 'Reverse' MFM pseudo-HDC & uC ||||||| ATA bus or equiv. ||||||| IDE/CF/etc. drive. Assuming that the chips are available it doesn't look too difficult to effectively clone a WD HDC and let it pretend to be a drive. What's the obvious flaw that I'm missing?

Emulex QD21 firmware

I've got an Emulex QD21 (Qbus ESDI controller) with a Rev. D firmware on it. The later revisions of this card (Rev.

The board doesn't look overly complicated to me (there is a raster image on the page I linked to), all it has on it besides a DIP-16 IC is a resistor, a tantalum cap and another axial component which is obscured by wires in the pictures, possibly a (zener?) diode.

One more interesting question would be what kind of lens is required for the recorder application. IIRC there are no refractive optical elements inside the recorder stand as it is now, the CRT faceplate is in plain sight behind a cover glass and the selected filter. I can't measure the distance right now as the recorder is in storage, but I'd roughly estimate somewhere around 20-30cm to the camera seating plane.

Users of K52 and K62 variants of KED

by jhfinedp3k＠compsys.to

Of the nine variants of KED developed by DEC, it seems doubtful that either K52 or K62 are in use at this point. I have mentioned in the past that a new variant, K42, which now supports a VT420 with 48 lines is available. Inspection of the code for K42 suggests that improvements can be made with respect to the allocation of memory. In particular, while K42.SAV is LINKed to execute under an Unmapped RT-11 Monitor, for versions of RT-11 which include VBGEXE, virtual memory can be used under a Mapped Monitor. These same improvements to K42 can also be added to K52 and K62 so that if these variants are executed under a Mapped Monitor, more efficient use can be made of the available memory. One of the improvements can be an increase in the size of the cut and paste buffer. If no one still uses a VT52 or a VT62 terminal, then there does not seem to be any point to including these improvements in K52 and K62. Please respond if there is any interest to actually use K52 or K62 under a Mapped RT-11 Monitor. Jerome Fine

Tektronix 4052 Firmware

by rickb＠bensene.com

Hello, all, I have a Tektronix 4052 Graphic Computer that I believe is in workable condition, but the old Mostek MK36xxx-series mask-programmed ROM that holds the operating firmware for the machine have failed, which is apparently a common occurrence for these devices. I have found numerous mention of these ROMs having been used in test equipment that "forget" after 10 to 15 years after production. I found the archive of 4052 firmware on Bitsavers, but am wondering if anyone out there has any suggestions as to what to do to replace the failed ROM with something of more current technology that will work. The firmware consists of 64K bytes of code. The Mostek ROMs are 24 pin devices, 5V supply, that use a clocked chip select signal, meaning that any replacement will have to emulate the clocking access scheme. There were Motorola-made programmable devices that could directly replace the Mostek parts, but these seem to be virtually unobtainable today..and even if I could find 8 of them, I don't have anything that could program them. Any other 8K x 8 ROM is in a 28 pin package, which would require some clumsy adapters to work. Along with the ROM itself, the 4052 had a unique ROMpatch implementation that allowed up to 48 ROM locations to be ''patched' in real time, and this involved a PLA device that did the address matching, and a fast bipolar ROM that contained that data to be substituted at the location to be patched. Duplicating the patched code could also prove to be very difficult. I am wondering if anyone out there may have run into the same situation with a 4052 and came up with a solution. Any help would be greatly appreciated. Thanks, Rick

PC-Write and PC-File Shareware

I am doing my once a decade or so clean up and sorting. I have found working distribution diskettes of the shareware software PC-Write and PC-File. I had to break-out a 5.25 inch drive to read these. My 2005 vintage XP machine only support on drive at a time so I have to open the case and hook up the 5.25 inch drive. I have transferred these disks to my network drive and have tested them on a Windows 98 laptop. I also have Norton Utilities and various copies of DOS going back to version 1.1. (Complete with packaging.) If there are any vintage PC users here I can email copies of the disk contents.

(It was from MPE, so it was probably: FCOPY FROM=space.oct;to= ) I noticed in your README you mentioned overflowing the terminal at serial speeds ... that's solved by using enq/ack pacing, a strap you can enable on HP terminals (also called "flow control"). It's been awhile since I've used it, but I found a writeup here: http://docs2.attachmate.com/verastream/vhi/7.1/en/index.jsp?topic=%2Fcom.at… And, from Robelle's website at http://www.robelle.com/smugbook/network.html we see: ENQ/ACK is a proprietary method of flow control used on Classic MPE V systems and is still built-in to most HP terminals and enabled by default. The transmitter sends an ENQ (Enquiry, decimal 5, Control-E) every 80 characters (or so). When the receiver is ready for more data, it replies with an ACK (Acknowledge, decimal 6, Control-F). If there is no reply in 10 seconds, MPE V resumes printing printing (Term Type 10). If you disable ENQ/ACK on your terminal, you will see output interspersed with pauses. MPE/iX and HP-UX normally use XON/XOFF Flow Control instead of ENQ/ACK. So...you could have a little C program that loops: while data left > 0 if >= 80 bytes then write 80 bytes of data write an ENQ (decimal 5) read, waiting for an ACK (decimal 6) (preferably with a timeout of a second or two, in case ENQ/ACK isn't enabled on the terminal) else write remaining data Stan

Film Recorders (Agfa PCR II)

by Arno_1983＠gmx.de

Hello Folks, the recent talk about film recorders here made me think it might be time to mention one of my "wish list" items here again, just in case somebody happened across it recently. I know this is going to be a long shot but here is: I managed to secure an Agfa PCR II from University, but unfortunately it is missing the actual camera/optics/tubus assembly. The physical interface for it is a spare metal plate with two alignment holes and two thumbscrews on diagonally opposite corners, and a strange round 12-pin threaded connector for power and communication to the camera (shutter release, out-of-film signalling). There are several options available (the most common being 35mm and Type 120), but either people don't know what they are (which makes them difficult to find) or they know it (which renders them unaffordable, cf. http://www.mops-computer.de/plson01_.htm ) The standard one seems to be the 35mm cartridge film module, a modified Nikon N6000 a.k.a. F-601M camera. If these do appear in the market, they are sometimes converted back to standard, which involves removing a small controller PCB and rejoining some wire ends, cf. http://photo.net/bboard/q-and-a-fetch-msg?topic_id=23&msg_id=001BtO . Please let me know if you have any leads on such an item.

Bits and pieces rescued from the remainings of the Computer Museum Aachen

by p.gebhardt＠ymail.com

Hi folks, I'd like to share with you my experiences, I made during March and April when most of the remaings of a big computer collection originally located in Aachen were thankfully mostly saved by the collectors in Germany. In March, there had been a brief discussion about remainings of the Computer Computer Aachen, Germany. As far as I understood, a couple of years ago, most of the collection could be saved thanks to the CHM and a donation of SAP, who made shipping from Germany to California possible from a financial point of view. The collection is since then known as the "SAP collection" and stored at the CHM.Bits and pieces, the CHM left behind in a warehouse in Dortmund, "re-appeared" in March. A very motivated person, who got informed about the vintage systems, tried then to locate and contact the renter of this warehouse via the landlord (which had to be located and contacted as well). It turned out that the content stored in this warehouse had to be cleared within 2 month, as the warehouse was going to be sold. This was a pure coincindence and destiny here was on the side of all those, who'd like to save ancient comouting systems from being scrapped, as that person actually tried to find collectors willing to save these remainings, as everything not saved would otherwise been scrapped. An post in a Robotron systems online forum (Vintage computer manufacturer from eastern Germany) had been placed with images of the parts. First come, first serve was the philosophy in order to give away for free the bits and pieces to collectors, whoever wanted to save these. I found the thread when I read about it here at classic-cmp, as another list member posted the information here and asked for information about and identification of the parts. So during the last three months, I went to this place more than once in order to try to save as much of complete parts as possible, I could, with the focus to get them back to working condition one day. During the first visit, other very nice collectors from eastern Germany were there as well. There was a very good atmosphere in trying to help each other to move heavy partsand cabinets around, to part with the bits in a fair way and to identify and estimate the conditions of these remainings. These are the days I like when you can meet new people who share this passion about vintage computing and save systems together from being scrapped. And that's how I have been knowing the collectors community in Germany so far. But for the first time, I also experienced different attitudes in this domain. With time, the discussions in that robotron thread where marked by rough tones of a person who stated that the remaings left behind by the CHM in that warehouse where "rejects" and therefore not worth or at least not interesting being picked up because of probably being incomplete and he treated the person who discovered the whole thing and opened the thread as unfair, as he felt the systems were already rewarded to others under doubtful circumstances. Another bad surprise, we had to face, was the behavior of a collector who was at the warehouse earlier than me and who took the opportunity to take with him two EAI 2000 analogue computers for somebody else, I originally was supposed to deliver to. The person in charge at the warehouse confound that guy with myself and asked him, if he was the one supposed to bring these machines to the person, who claimed interest in these. He said "yes" and took everything with him. Call it what you want, but that's seriously the first time, I face such nasty behaviour to put hands on vintage computers! I'd say that the real condition of a big lot of machines can only be identified properly, when being on site. That's exactly what I did. I stated interest in some parts of which I knew for sure that I could store them savely, in case their condition was satisfactory enough to resurect them to working condition one day. I also tried to save things which should belong together. Too bad, I was limited in space (the eternal problem). Otherwise I would have saved more. Anyway, the following could find a new home within "my walls". two Honeywell Bull Datanet systems (on Level 66 basis), can be hopefully transformed to normal mini-computer with approriate software Honeywell Bull reel tape drive with vacuum columns, complete (rebadged CDC tape unit, probably of type 669) Honeywell Bull terminal and printer Honeywell Bull disk drive (rebadged CDC BR3D4) with spare parts from another incomplete drive Control Data 604 Tape Transport Unit, all logic boards missing Control Data 854 Disk Drive, seems complete Control Data 841 Multiple Disk Drive, saved complete electronics and one complete disk unit with its hydraulic actuator, had no space for the entire cabinet :( Telefunken MDS-252 reel tape drive with vacuum columns, complete? (belonged to a TR-440 mainframe) Telefunken TR-4 console, complete? (rebadged IBM typewriter) Telefunken WSP-414 disk drive (rebadged CDS-drive) with concentrator-unit (complete) in order to connect up to eight drives to the TR-440 mainframe Telefunken LSS-150 power supply of a Facit paper tape unit DEC RP03, (ISS) with spare parts from another damaged and incomplete drive Pertec reel tape drive, complete NCR reel tape drive (rebadged CDC BW303 tape transport), one small PCB missing Logic boards from a CDC 608 tape unit (according to the person who organised the give-away, nobody ever showed interest in taking the complete unit) Unfortunately, I couldn't find documents online about all of these parts. So I'd kindly like to ask the list, if anybody has documents about the following ones, so that I could ask them in future, when I come to the point where I can start restoration of these: - CDC 604 and BW303 tape drives, 854 disk drive and 841 multiple disk drive - Honeywell Datanet (or Level 66 minis) documents and software - Telefunken schematics As you can see, I focused on peripherals, due to my particular interest in disk and reel tape drives. Maybe, a running Honeywell system can be obtained out of the stuff, I saved. Let's see how much can be resurrected of these in the years to come. Biggest problem regarding the disc drives will certainly be the missing disk packs and the probable re-calibration of the disk and tape units. The disk packs, I got from there, were all coroded to such an extend that they are most probably useless. The DEC RP03 drive came with two document binders containing schematics. Haven't seen them on bitsavers, yet, and will therefore scan them in near future.

Three Tons of Minicomputers

Hi This is a shameless plug for something I and the Update Computer Club have been working on this spring and opened yesterday. The exhibition "Three Tons of Minicomputers" at Museum Gustavianum in Uppsala, Sweden. We have collected computers primarily used by the university at some point in time. Highlights include a Linc-8 and a DECSYSTEM-2060 with peripherals. Here are some pictures from the opening: http://www.update.uu.se/~jeppe/tmp/vernissage/ I strongly recommend anyone nearby Uppsala this summer to take a swing by Gustavianum. If you want a guided tour, let me know and we'll figure something out. It's only open for a few months, so don't wait to long. Regards, Pontus.
