Locating older systems & parts... (was: RE: making disk images)

by cb＠mythtech.net

>Hoping to find a PCjr show up here is probably impossible. I thought I offered the PCjr to the list when I saw it there. No one responded, although the price they were asking seemed steep. $12.50 IIRC, for JUST the PCjr. No power brick, no keyboard, no monitor. Although it did have the parallel port sidecar. Alas, I only have one PCjr left myself, and I'm hanging on to that one. I had 50 or so a number of years ago, but they were all donated to a local school system. I might have an extra monitor left however, but I'm not sure. I should still have some PCjr video to CGA pigtails, but they are all home made (not by me, but by another employee here), and I think someone on this list posted the pinouts for such an adaptor some time back. -chris <http://www.mythtech.net>

Hi all, unfortunatelly one of my two RD54 hd (by Maxtor) in my mvaxII kept doing strange sounds at startup. It isn't coming on line as before, now it takes a lot of time while a continuous noisy sound comes from it, and after it seems sufferig of read problems at bootup. Any info/advices about RD54 and it's strange sounds will be greatly appreciated. ... Franco Tassone

fair price for apple articles

by cb＠mythtech.net

>> 2 Apple II GS, a IIc (claimed to be new in box), a Mac Plus, couple monitors, >> external floppy and hard drives and "scads of software and manuals". > >$100 is fair. WOW! I can't believe Sellam of all people over priced this bundle. $100 is very generous for what is listed. Unless there are some really unusual monitors or software/manuals, then I don't think the lot is worth more than about $20, and that is more as a "thanks for letting me have it" gesture. I have aquired everything mentioned above (catagorically, obviously I don't have specifics on the monitors, drives, software, manuals), from the curbside garbage in the last six months. There could be things that bump the value up a bit. Such as the IIc being truely brand new never opened (and not just clean and reboxed). If the IIgs are Rom 0 units (or Woz units), and if the monitors or hard drives are large (20" monitors, and 10+ gig drives). The software and manuals, unless it is current release stuff, exotic hard to find stuff, or things you care about owning real copies of (vs abondonware copies), then it is of little value. Bear in mind, even if there are parts that pump up the value, you need to overcome the $20 "thank you" price first, so you start at $0 and go up, not start at $20 and go up. -chris <http://www.mythtech.net>

Compaq Portable & Portable III Free to a Good Home

by bill＠timeguy.com

I have an orginal Compaq luggable (green screen) and a Portable III (orange/amber plasma screen) that are under foot. If you can pick them up in Nebraska, they're yours. If you want me to ship them, I'll let Mailboxes Etc. do the packing and shipping, so it won't be cheap. Both work fine and are in excellent condition. The III is like new; I replaced the old plasma screen (which was badly burned in and faded) just before I quit using it. It also has a removable "backpack" on it with two ISA card slots for network cards or whatever. First come, first served.

VAXstation 4000/60 /90 question

by healyzh＠aracnet.com

I've managed to find the pieces (or at least the most important, which is one of my two RD54's) to do some performance testing on Doc's recent idea of using a network disk instead of a local disk to get better performance than a RQDX3/RD54 combo offers. As a result I'm trying to get either a VAXstation 4000/60 or /90 setup so that I can use it as the host. In doing this I ran into a slight problem with VAX/VMS V5.5-2, it doesn't like my 3rd party SCSI disks that I've got in the /90. Not a big problem as I've got some brand new (!) RZ25's that I can put into one of the systems, and I want to put a RRD42 into one of them as well. Stupid question, how to I go about getting the cover off of the 5 1/4" bay, and am I supposed to have another piece of plastic to go there? If it requires another piece of plastic (that I don't have), I'll just hook the drive up internally long enough to do the install. Now to decide which system gets a V5.5-2 install, I'll probably go with the /90 as it's my fastest VAX, and will therefore be the best for building software on. Zane -- | Zane H.

DOS compatible mode for HP 9127?

The HP 9127 is a HP-IB 5 1/4" floppy drive and normally it reads and writes a LIF format but there's supposed to be a way to have it read and write disks in a MS-DOS compatible mode. Does anyone know how to do it? I've been playing with different formatting options but so far I haven't found the right one. Joe

DaynaFile

by ericj＠speakeasy.org

Has anyone managed to find drivers for the DaynaFile? I have a couple I'd like to experiment with. One non-functional, unfortunately, but I pulled the rom on it to image it and attempt a disassembly. I have another that appears to work, or at least responds to a scsi inquiry. I plan to hook it up to a logic analyzer to get a memory map of the board. The logic boards on the two I have are simple, with common parts in clip-friendly 40-pin dip packages: scsi: DP5380 floppy: WD2793 micro: 8031 Documentation is available for all of these, so a person could potentially write new firmware. Probably much easier than disassembling the rom. I remember using a DaynaFile on a NeXT cube with an old (ca.1990?) version of Nextstep, so there are potentially Nextstep drivers out there as well.

resurrecting a PDP-11/10

by Andreas.Freiherr＠Vishay.com

Barry, didn't you ask (under the pseudonym of Fred Feuerstein) for a description of the switches on a DS120 Terminal Controller? I managed to find a user manual from the stone age, stating that the "Logic Card" is part number 512000-2. Not quite the 5120000-1 that you mention in your posting, but possibly close enough to provide hints for what functions might be there. YMMV... This is what the manual says about the DIP switches: SWITCH FUNCTION 1 Carriage motor disable (test only) * 2 Reverse channel override * 3 FDX/HDX override * 4 Local Auto-LF override ** 5 Parity odd (ON) parity even (ON) ** 6 Parity enable (ON) parity disable (OFF) 7 AUTO-LF from line (ON) disable (OFF) ** 8 X-on, X-off handshaking enable (ON) disable (OFF) * On DECwriter models with the 8-key control pad, these switches are duplicated on the keyboard. Those models with the 3 rocker-switch panel must control these features with the DIP-switches. ** See Appendix B, "Additional User Information", for a functional description of these switches. End of cite. Appendix B talks a lot about half-duplex modes, which I presume will not be used with your PDP-11. Hence, you will want to have switches 2 & 3 in the OFF position. The description of switch 5 obviously contains an error. For even parity, the switch needs to be in the OFF position (says appendix B). Another noteworthy cite: "If parity is disabled by DIPswitch #6 "OFF", then DIPswitch #5 provides 8th bit spacing when "ON" and 8th bit marking when "OFF"." In other words, you actually cannot select "no parity", but you can set "mark" or "space" parity. You report having trouble with the 20mA interface. Maybe you need to switch from active to passive or vice versa? - Here's what the manual has about it: 3.1.3 20 MA CURRENT LOOP A 20mA current loop interface is provided featuring a photo isolated receiver and transmitter. The receiver and transmitter may be configured to operate in either passive or active mode. Unless otherwise specified at the time of purchase, the DS120 comes configured with a passive transmitter and receiver. Although specified at 20 mA, the signal line currents flowing in the receiver loop may be as high as 80 mA without harming the interface. Any current in excess of 15 mA will be interpreted as a mark, and any current under 3 mA is interpreted as a space. 1500 volts of isolation is provided by the photo isolater if passive is employed. The jumper configuration for the current loop interface is as follows: W1 W2 W3 W4 W5 W6 W7 W8 W13 W14 ------------------------------------------------------------------- PASSIVE Out In In In In Out Out Out Out Out ACTIVE In Out Out Out Out In In In In In The connections for this interface are as follows: PIN 2: Transmit - 3: Receive - 5: Transmit + 7: Receive + End of cite. Hope this helps. If you need more information, I can get whatever is printed in the manual for you. I do have a LA36, but it features the original DEC controller board, so I have no way of actually trying anything. -- Andreas Freiherr Vishay Semiconductor GmbH, Heilbronn, Germany http://www.vishay.com

DEC VS2000 and SCSI, was Re: DEC RD54 from Maxtor

by classiccmp＠crash.com

John Allain writes: . > Somebody should say here that it's pretty strange to have a > workstation that has all SCSI connectors on the outside and > an MFM disk on the inside. I did a mental doubletake on this > ("hey, this makes no sence") a short while ago. Since I haven't seen any other responses, I'll dive in... This is all speculation - I'd love to have someone with a line into DEC Engineering answer this properly. To put it another way, I may be completely off my rocker - reader beware! ;^) The VAXstation/MicroVAX 2000 was released in 1985 (cf. R.D. Davis' uVAX FAQ), which means development and planning may have started as early as 1983 - I'm just guessing here. In the early 80s large (> 20MB) ST-506 hard drives were still hugely expensive beasts. If you did find a native SCSI device, I imagine the costs would be much higher for the extra interface logic on the drive. Without native SCSI on the device, you needed a translator like the Adaptec ACB-4000 (SCSI/ST-506) or Emulex MT-02 (SCSI/QIC-02). The base VS2000 was a pretty small box - perhaps even ground- breaking for this timeframe, given it could run full 32-bit uVMS or Ultrix and had internal storage, unlike the Sun-2/50. Having to develop and wedge in a unique converter board may have been riskier than adapting a version of a board you were already producing/ designing for the other uVAX models like the RQDX3. Going back to that comparison to the Sun-2/50 may answer the question of why SCSI was acceptable for the tape interface. Since the tape drive was going to be external, there's plenty of room for that extra logic board. And it's only a tape drive, so if we can't get decent throughput out of our first (?) SCSI interface, well, who's going to notice when the tape drive is as slow as the TK50? ;^) After a few years of Apple, Sun, and others driving SCSI into the marketplace the whole picture changed and by the time the first pizza box workstations come out everything is SCSI. Anyway, that's my best shot at an explanation. Again, I'd love to hear from someone who was inside DEC (Megan?)... --Steve.

Yes :-) The MAN series used to be popular but I'm afraid I don't have any data. However, I do have a data sheet for the DS8867 -- it gets a page-and-a-bit in the 1980 Nat Semi Interface Data Book: DS8867 is an 18-pin DIP 8-segment constant-current driver, designed to be driven from MOS circuits operateing at 8V +/-10% minimum, and will supply 14mA typical current to an LED display. Output current is not sensitive to Vcc variations. Features: internal current control - no external resistors 100% efficient - no standby power operates in 3- and 4-cell battery systems inputs and outputs grouped for easy PC placement Absolute maximum ratings: Vcc 7V input voltage 10V output voltage 10V Operating conditions: Vcc min 3.3V max 6.0V ambient temperature min 0deg C max 70deg C logical '1' input typ 4.9V max 5.4V logical '0' input typ 0.1uA max 10uA logical '1' output min -8mA typ -14mA max -18mA logical '0' output typ -0.5uA max -10uA Pinout is straightforward, pins 1..8 are inputs 1..8, pin 9 is ground, pins 10..17 are outputs 8..1 (ie the outputs are almost opposite the inputs), pin 18 is Vcc. -- Pete Peter Turnbull Network Manager University of York

King of the string has Stringy floppy day

by rborsuk＠colourfull.com

Hi All, Thanks to Glen I now have info on my A&J Microdrive. On another note, I have just received in today a Stringy floppy for the Commodore 64. This unit is brand new and has a brand new tape. It connects up to the cassette port. Though I won't have time to test the units (the wife calls it play) until thursday, at which time I will declare it "Stringy Floppy day". Anyway, anyone have experience with a stringy floppy for a commodore? It's called a "Quick Data Drive". Thanks Rob (self appointed king of the string) (just kidding) Robert Borsuk - rborsuk(a)colourfull.com President Colourfull Creations http://www.colourfull.com

Dual File Structure CD for RT-11

If you want the disk bootable, then 2-5 are absolutely required. Typically, blocks 6 through 6+(2*31)-1 are required for the directory, but the home block contains a value where the directory is supposed to start... but I don't believe that RT actually uses this field, and many utilities certainly don't, assuming the directory starts in block 6 (not to mention user programs).

Dual File Structure CD for RT-11

by jhfinepw4z＠compsys.to

I don't know how many people might be interested, but I have finally been successful in creating a Bootable RT-11 CD which also has the standard ISO file structure. However, the really key point is that none of the files on the CD are duplicated. On the other hand, I am unable to test the CD that I just burned using real DEC PDP-11 hardware since I have never tried very hard to find and successfully test a CD-ROM drive with a SCSI host adapter on the Qbus PDP-11 which is available for such purposes. But, using the Full Commercial Ersatz-11 running under Windows 98 SE, I just did the commands: MOUNT DU0: SCSI0: BOOT DU0: I assume that if I had a suitable real DEC PDP-11 system with a SCSI CD-ROM drive, the exercise would work there as well since I know that others have been successful with an RT-11 ONLY CD that boots on real DEC PDP-11 hardware. Since many of you reading this who don't know much about RT-11 will likely be confused, let me describe very briefly how I started. I first took 4 RT-11 RL02 bootable images or DSK files, each being 20450 blocks long. Since only the first 5000 to 6000 blocks of each file contained useful non-zero information, I reduced each image to the size that did not contain any blocks with all zeros so that all 4 RL02 images would fit into a single RT-11 partitions of 65536 blocks. I then used Nero Burning under Windows 98 SE to copy all 4 RL02 images to a CD which had the standard ISO file structure after which I copied 24612 blocks from the CD-RW to a file under Windows 98 SE: Blocks 0 to 63 - All zeros Blocks 64 to 99 - Standard ISO file structure Blocks 100 to 24599 - The 4 files Blocks 24600 to 24603 - Extra information for the standard ISO file structure Blocks 24604 to 24611 - All zeros The first file from block 100 to block 5192 was the RL02 bootable image for V5.03 of RT-11. There is one technical problem I have not solved - the current test was done with a CD with an image that is identical to a file of 24612 decimal blocks - which is less than one full RT-11 partition. If I am going to be able to use a CD with more than 65536 decimal blocks of files (i.e. more than one full RT-11 partition), I will have to solve one critical problem. I must find a method of preventing any files under the standard ISO file structure from using any CD sectors that fall in the first 16 that start on a multiple of 16384 sectors (of 2048 bytes which is how a CD is written for those users who might not know). These number correspond to the first 64 blocks that start on a multiple of 65536 blocks (of 512 bytes) on a hard disk drive which corresponds to each RT-11 partition. Before I describe the details, note that the method is probably useful ONLY when the CD contains a limited number of large files. This is because the RT-11 directory on the CD must be mostly constructed by hand at the present time. The first step is to create an exact copy of a CD which has been burned with the desired DSK files. This image file can be created using PUTR to specify the exact size plus E11 and RT-11 to copy all the blocks from the CD to the image file. The critical reason that everything works seems to be a rather fortunate use of the mutually exclusive areas by the RT-11 file structure and the standard ISO file structure. While RT-11 requires the first 64 blocks (of 512 bytes) for the boot blocks and file structure, the standard ISO file structure uses the next 9 sectors from sector 16 to sector 24 (of 2048 bytes) which allows the RT-11 DSK files to start at block number 100 or sector number 25. All that is required (from the RT-11 file structure for the RT-11 DSK file that is in the first RT-11 partition) is to copy the RT-11 file structure (ONLY - i.e. just blocks zero to where the directory segments stop) to the start of the image file (which is initially identical to the ISO file structure CD image with the DSK files placed on the CD using standard CD burning software - in my case I used Nero Burning on a CD-RW so that I need not toss the CD). I produced that image file by using E11 and RT-11 to copy the CD-RW image to an existing file under Windows 98 SE. In my test, since I chose the first DSK file which started at block 100, the next step was to add 100 to the starting block number in each directory segment. The final step was to then select the monitor that I wanted to boot and write the correct boot programs into block zero and 2 through 5 of the image file. All of the extra steps were easily accomplished using E11 and RT-11. The following summary probably helps: RT-11 file structure: Blocks 0 to 63, Sectors 0 to 15 ISO file structure: Blocks 64 to 99, Sectors 16 to 24 RT-11 files: Blocks 100 to 65535 for partition zero ISO files: Sectors 25 to end of CD To create an RT-11 bootable CD, I copied the original CD image to a Windows 98 SE file on the hard disk. I then copied did an INIT DU0:/VOLUME under RT-11 after which is copied blocks 106, 107, 108, 109, 110 and 111 to blocks 6,7,8,9,10,11. The SIPP was used to add 100 (144 octal) to the fifth word in blocks 6, 8 and 10. The last step was to use the RT-11 command COPY/BOOT DU0:RT11XM.SYS DU0: I then had to use the "Burn Image" option under Nero Burning to transfer the complete file back to the CD (after I had erased the files of course) since I do not have any software to write just the first 3 CD sectors. One other aspect is also permitted under RT-11. Since every RT-11 directory segment contains the starting block number in the fifth word, it is possible to have the ISO file that is a bootable RT-11 image of some device referenced both by each file AND as a single DSK file starting with a new directory segment at the end of all the individual files. In my actual test example, there were FOUR bootable DSK files under the ISO file structure (within RT-11 partition zero). The first 3 RT-11 directory segments (starting in block 6 of the CD) contained file headers for 206 files. An additional directory segment was then added (manually one word at a time with SIPP) which had an empty area starting at block 100 with sufficient space for the FOUR bootable DSK files. CREATE was then used to set up the file headers one at a time. Obviously RT-11 is being "fooled", but it does work! The net result is that it is possible to use the same files under BOTH the standard ISO file structure AND the RT-11 file structure. While all of the above was done on a Pentium system running Windows 98 SE, Nero Burning, Ersatz-11, PUTR and RT-11, I am confident that other operating systems and software utilities would also be successful. The actual concepts are really very simple. Implementation of the test case did take almost a week since I made a lot of mistakes along the way. But at this point, I could duplicate a second test in a few hours. If there are any questions, I will be glad to answer them. I do have one request. Does anyone know how or if it might be possible to write a program that can take the image of the CD after it is copied to a file on the hard disk and copy all the data to a second slightly bigger file. The key requirement would be that the blocks at multiples of 65536 (where RT-11 partitions start - actually 64 blocks in each of the 20 possible RT-11 partitions) would be left empty. I would imagine that a simple FORTRAN program could do this if the ISO file structure is known since all that would be required would be to change those parameters which specify the sector number where the file starts - AND move the associated file up in the CD image in the destination file so that 16 sectors starting at multiples of 16384 sectors are left empty.

Monitor screen width adjustment?

by avickers＠solutionengineers.com

Hello again, I've got a Sinclair (well, Amstrad really, but it has Sinclair printed on the front) monitor here, which claims to be a QL monitor. To the extent that it has a captive QL-specific signal lead... However, the display is too wide, and marginally extends past the bezel in both directions; only by about 1/4 of one character or so, but just enough to be seriously annoying. So, today, I whizzed the back off to adjust it - but there's no "horizontal size" pot :( There are trimpots for V.size, H.hold and Sub-bright. There's adjusters for focus & brightness (or maybe contrast, it was hard to tell since it was simply labelled "Screen". There's also externally accessible controls for V.hold, brightness & contrast. On the back of the tube, there's trimpots to adjust red & blue intensity (with two pots per colour). It looks like there ought to be a green pot as well, but there's no trimmer there, just a fixed resistor. So, is it the case that I cannot adjust the h.size? Is it a case of go rooting around looking for the component (a resistor, I assume) which sets this, and replace it with a pot? Any advice appreciated. -- Cheers, Ade.

Thanks for suggestions with my "build a PDP" project

by ssj152＠charter.net

Thanks, everyone for your suggestions regarding SCSI controller for RT-11, DECserver in Kansas City, etc. All of this is leading up to me building a PDP-11 SOMETHING out of parts I can afford. I've worked with Mike McFadden and he bought the rack of equipment containing the terminal server and is selling me the CPU board; Thanks to Jonathan telling me about the auction, I bid on and won the "LSI-11 Box Blow Out" on eBay PLUS the QBUS chassis (sold separately); Watch for me to announce the availability of the 11/23 CPU's and other boards from this auction. Hopefully the sale of some of these things will defray some of the expense of the construction of the PDP-11. I already have a pair of SSSD 8" floppy drives I bought to use with E-11 and PUTR to copy from my PC to RT-11 RX01 floppies - now I need to buy the adapter board from John Wilson to connect the big floppy's to my old 486. I have a DECserver 550 with its CPU and CXA16's; I may use the chassis and the CPU, or just the one from Mike McFadden. Then again, I have enough stuff now that I could build two systems. I have a RQDX3 and RX50 for a floppy interface to the prospective PDP-11. I'll use one of the drives from the "Blow Out" in the new system. The chassis I bought in the "Blow Out" has a foundation module with disk controller, etc. on it, so I may not need these items. I have 2 Ethernet controllers, the one from my original DECserver 550 and a DEQNA I recently bought. One of these is likely to go. It seems to me I am almost set - all I have to do is get all the stuff here and set it up :-) that should be a SNAP - right? Lets see - ~1978 to 2003 is how many years old this stuff is??? Only 25 or so. Should be no problem <g>. Regards, Stuart Johnson

FS: Dec Gigi (VK100)

by pat＠purdueriots.com

I've got a DEC GiGi that appears to work, but has some cosmetic damage, and is missing a few keys. The keykaps are the same style as used on the Decwriter III, IV, and other DEC equipment. The missing keys are the 6-9 keys on the QWERTY section, PF1, PF2, and 9 on the numeric keypad. I've hooked it up to a monitor, and it gives an output as I type on it, so it probably works just fine. $5 + shipping from Lafayette, IN. I take cashiers check/money order, or paypal.

On all the Amsturd monitors I've had the width is fixed and can not be easily adjusted. It's not a pot or resistor that you're looking for, it's a coil, usually about 1/2" to 1" in diameter and with a ferrite I core. If you're lucky it will have an adjustable core but I have yet to see one in an Amsturd. If you find the coil (you can tell because bringing a metal tool up to it will change the width/centering) you may get away with glueing a lump of ferrous or non ferrous metal to it (one will make the picture wider and one narrower, I can't remember which off hand). If this then offsets the picture a small permanent magnet can be used, on the width coil, to pull it back.
