Be glad you don't have to deal with this kind of thing: http://everist.org/pics/misc/20200719_6831_wet_tapes.jpg A bunch of PDP 8 system tapes. That were literally soaking in liquid water when recovered. Yes, that is mildew. They are nearly dried out now. Still to be determined if they can be manually teased apart intact enough to be read. After deciphering what they all are, from remnants of the labels and a paper list that was with them. Hopefully these are already online somewhere. If not, then a lot of work to recover. The DEC mag tapes... sigh. Still not even thinking about them. Just slow drying. Guy

OS-9/68k Control Coprocessor module

by chd＠chdickman.com

I came across an Allen-Bradley 1771-DMC4 Control Coprocessor. If you are familiar with AB PLC's, it is a 1771-IO chassis module that could be a "sidecar" for a PLC5 PLC or a standalone module. It runs some version of OS-9/68k on a 68340 processor. It has 4MB static ram and a 10MB ethernet AUI connector. I hooked up a terminal and can get to an OS-9 prompt. It has by default a 64k RAM disk that is empty. The best I can gather is that there was an external IDE (AB 1771-PCB PCbridge) that was used to create programs that were loaded onto the RAM disk. Once configured it would run standalone. Microware is still around in some form so OS-9 is not completely dead and I did find some references to a Microware product called PBbridge. It would be interesting to experiment with. I am curious if anyone has any experience with this hardware, with the IDE or OS-9/68k in general. I've never seen much discussion of OS-9/68k on classicmp.

paper tape archiving

by billdegnan＠gmail.com

Hi all. I was wondering if there are any good online resources on reading for the purpose of archiving 8-bit papertapes of unknown origin. I have been reading tapes as text and also as binary, 8/n/1 thinking that's going to capture everything. I load into a hex editor, and if necessary convert to octal. I am wondering if there any persons who have a systematic process they'd like to share for this kind of work. I will share the tapes I have with the community, but there is no point if I am not doing it right. Thanks Bill

Comp.lang.forth: banned on google groups?

by dfnr2＠yahoo.com

I was looking for an old post on comp.lang.forth, and was surprised to discover that the group doesn't appear to be hosted on google groups any more.? Searching the group pulls up a "banned group" message, and selecting the "continue to the group" button shows 0 messages in the group.? This appears to be due to spam showing up in the unmoderated group. Google bought Dejanews years ago, and, as I understand, was the defacto main usenet repository.? Is is all really gone, or just temporarily hidden?? How long ago did this happen?? Is the full comp.lang.forth archive available anywhere? ? I wonder if it's time to set up some NNTP mirrors and gather as much historical usenet content as possible.? Much of the overall content is garbage, but there's some priceless stuff in there, and even more that will become interesting in light of future developments. Dave

Morrow MD3 terminal emulation.

by technoid6502＠gmail.com

I've got a Morrow Microdecision 3 on the bench and gather it often shipped with the MD-60 terminal, but for the life of me I can't find what emulation that terminal uses. Lacking the native terminal, what emulation should I be using? Thanks! Jeff

TRS 80 Model 12 Picked up

by lyokoboy0＠gmail.com

Greetings. It has been an interesting day. Rather late in the day, a buddy notified me of a local thrift store that went under, and mentioned there may be some computers on site up for grabs. Upon arrival, the place was a mess, but the folks there were friendly and gave me the tour, everything had to go, the shopkeeper skipped town and left the place full of junk for the Building owner to clean out. I found a TRS 80 Model 12, a vga commodore branded monitor, commodore cassette drive, among some misc 5.25 floppy disks. There may be more, I need to go back for another sweep in the morning. The computer is extremely big, taking up an entire kitchen table,rivaling the space that is taken up on my desk for a pdp 11. I am looking to clear a space to work on it without dropping parts. The machine looks to be clean, However i am missing the keyboard. The machine does not power on or show anything on the screen. I do hear a high pitched hiss, so there may be some kind of power supply issue. I was not aware of this model of machine, I am curious if anyone has a spare keyboard for sale. I am not familiar with this model, it has 2, 8 inch floppy drives on the front. I am curious about the format of the disks, would it be possible to use another computer with an 8 inch drive to make a floppy to start the machine, or do the drives use an odd difficult format that would be impossible to write? http://devindamico.com/Uploads/TRS80M12.jpg --Devin D.

MS-DOS 2.11 Assign.com

by r_a_feldman＠hotmail.com

I'm trying to copy files off my Otrona Attache 8:16 using FastLynx 3.3, but I keep getting an error 708 when trying to push SL.EXE to the Otrona over the serial port. I am wondering if the reason for the error is that the Otrona does not have a C: drive. Therefore, I would like to try to use Assign.com to assign C: to A:, but the Attache version of MS-DOS 2.11 does not include Assign.com. Does anyone have a copy of the MS-DOS 2.11 version of Assign.com they can send me? Thanks, Robert Feldman

CLCC68 Covers

by pbirkel＠gmail.com

I intend to restore a pair of boards that used Intel Ceramic Leadless Chip Carrier (CLCC) parts. Unfortunately the socket covers were tossed when the boards were scavenged for their chips. The sockets and attached clips are themselves just fine. eBay item # 252830664338 is an example of this style of 68-pin socket. Item # 362702811275 is an example IC in CLCC form. If anyone has a par (or even just one) of these covers lurking in their odds-n-ends collection somewhere I'm interested in putting them back into service. Thank you for taking a look! paul

chaos and the LGP-30

by wrcooke＠wrcooke.net

The LGP-30 has been discussed here (often fondly) a few times so I thought this might be of interest. Adds a bit of fame to the little guy that I wasn't aware of. I was reading the wikipedia web page on chaos theory and found this passage: "Edward Lorenz was an early pioneer of the theory. His interest in chaos came about accidentally through his work on weather prediction in 1961.[12] Lorenz was using a simple digital computer, a Royal McBee LGP-30, to run his weather simulation. He wanted to see a sequence of data again, and to save time he started the simulation in the middle of its course. He did this by entering a printout of the data that corresponded to conditions in the middle of the original simulation. To his surprise, the weather the machine began to predict was completely different from the previous calculation. " https://en.wikipedia.org/wiki/Chaos_theory#History Will

Broken VT510

As noted, in another reply, the DEC VT-5xx terminal series was mfg. by ADDS. Boundless Technologies (former ADDS) shutdown sales a few years ago.

Are the schematics anywhere? Not on Bitsavers as far as I can see. Are other terminals at all similar? The newest schematic I see is for the VT340. It would be nice to get the terminal working again. Alternatively, a wild idea would be to use the CRT in place of the "screen fungus" infested VR201 CRT I would like to repair. Any chance of that working? paul

Any interest in "newer" hardware, software?

by boris＠summitclinic.com

Mike: Just looked in more detail at photographs of my notes in drive box and appears I did verify that drive motor worked in 1987. Project to get this drive connected to my C64 got derailed by my being accepted to medical school a couple of months after my last interaction with that drive. Was somewhat surprised to discover that 8" floppy drive as I thought the Vic20 box had my other TI99 computer which might have been lost at some point in last 30 years and multiple moves. Never had a chance to try reading an 8" PDP-11 floppy in it and no longer have any as all of them went to Glen Slick in 2008 when he got my MINC and related hardware. There was an interesting computer surplus store in Seattle that I no longer recall name of, but one of landmarks was a company that sold Buffalo Wipes nearby. Unfortunately places like this no longer exist and remember it being crammed full of various bits of electronics that would have to be lifted out of way to see what was buried underneath. Easy to spend a day in there poking around. Everything was as-is and often just good for parts. Location you've specified as a means of transferring drive a good one and a short drive >from Kamloops and one I like doing but unfortunately limited to Canadian side of border now. Did run across a couple of 80486 boards today and must have played with them as found some 80 Mb HDD's in same box. One was fully loaded with about 8 Mb of RAM!

Altair 8800 reproduction

by stephen.m.pereira.sr＠gmail.com

I had the same confusion about Mike?s Altair 8800c not being a complete kit, and wondering what it would take to ?upgrade? my Altair 8800 Clone to be a real Altair 8800c a bit more than a year ago. I ended up not finding very much assistance at the time, so I bulled my way through it, and got it done using the info and pointers from Mike?s site. Another time someone asked about this I posted my experience on the VCF. See this: http://www.vcfed.org/forum/showthread.php?69929-Altair-8800-clone-cost-to-b… <http://www.vcfed.org/forum/showthread.php?69929-Altair-8800-clone-cost-to-b…> Mike?s original topic on VCF is here: http://www.vcfed.org/forum/showthread.php?66737-Building-and-Altair-8800-fr… The bottom line is that you *can* get it done with the info and pointers that Mike provides on his site. He is also reachable on the VCF and also by telephone. He is tremendously helpful and will answer any questions that you may have. smp - - - Stephen Pereira Bedford, NH 03110 KB1SXE > On Jul 24, 2020, at 1:00 PM, cctech-request at classiccmp.org wrote: > > > Message: 13 > Date: Fri, 24 Jul 2020 11:15:34 +0800 > From: Tom Hunter <ccth6600 at gmail.com> > To: Greg Beat <gregory.beat at gmail.com> > Cc: "General Discussion: On-Topic and Off-Topic Posts" > <cctalk at classiccmp.org> > Subject: Re: Altair 8800 reproduction > Message-ID: > <CAALEduAsERN897fBN8rDCqt_mN6wHc2J8qSDzYyhfU2CibmiJQ at mail.gmail.com> > Content-Type: text/plain; charset="UTF-8" > > Hi Greg, > > I saw Mike Douglas' Altair 8800c but he writes on his website that this is > not a complete kit.

IBM 3194 VDU (WTB/pinout).

by andrew＠carrierdetect.com

I have an IBM 3194 base unit and keyboard, but no monitor. Hence would like to try and source a suitable monitor and any suggestions on this front would be appreciated. Failing which, also considering the possibility of using some other non-original monitor, but not sure what the interface (15-pin D type, but standard density) is and pinout etc. Also potentially interested in offers of other 3270 displays (off-list).

Altair 8800 reproduction

by ccth6600＠gmail.com

About 10 years ago Grant Stockly in Anchorage Alaska produced high quality MITS Altair 8800 reproductions in kit form. The website still exists: http://www.altairkit.com/ I have tried to contact Grant but did not get a reply. Does anyone know if these kits are still available? Is Grant on this forum? Alternatively is somebody else making complete Altair 8800 kits? I have found people making individual boards but not a complete kit. There is also the Altair 8800 clone which is based on a PIC microcontroller emulating the entire original Altair 8800. It is cute but not the real thing. Thanks Tom Hunter

Getting files off a 7300

by cz＠alembic.crystel.com

Anyone know the best way to get files off an AT&T 7300/3B1 computer? This one has a lot of Perq stuff in a directory as well as hilarious things you can do with RP06 disk platters (ah, when we were young...) It does have an AUI Ethernet port on the back, but doesn't appear to have TCP/IP installed. Maybe I can install TCP and find my old Synoptics 10bt to AUI adapter? CZ

HP3000 Microcode is in SYSDUMP (backup) for WCS machines (64,68,70, 37,...)

by rdbrown0au＠gmail.com

If written on a Series 64, 68 or 70, or on the Series 37 or it's successors, the first file on a SYSDUMP (Backup) tape may include the Microcode from the WCS (Writeable Control Store). Please collect such files if you have tapes available that you can read. Note that the first file includes a concatenation of system objects, ending with (optionally) the directory so that may leak data that should remain private. It's possible that the distribution tape for MPE V Release 3P G.40 that the HP Computer Museum has http://www.hpmuseum.net/display_item.php?sw=442 might also include the WCS data. The bootable disc image for the Series 37 and it's successors will. The Museum website doesn't mention media for their 68. Thanks as always to Al Kossow for his BitSavers work. 30140-90045_Series_64_68_70_Microcode_Manual_Oct86.pdf has a 543 page listing of the microcode assembly output, which should wait for better OCR software.

Looking for copy of BASIC ROM for HP 3396B Integrator II

by Martin.Hepperle＠dlr.de

Recently, I obtained a HP 3396B Integrator II. This is a device for the chemical analysis laboratory. I had hoped that this device contained a BASIC interpreter, but this was not the case. Through the serial interface I can connect a terminal program. Pressing CTRL+BREAK outputs the sign-on message serial interface: ~~HP3396,IBLI Unfortunately, typing "BX" for "Basic eXternal" on the keyboard tells me: BASIC NOT INSTALLED So I am wondering, whether I can install a BASIC by replacing the ROM with an EPROM. According to the "Installation and Service Manual", the ROM U 110 came in two versions: Z-80 Standard-ROM 03396-80012 Z-80 BASIC-ROM 03396-80032 This means that the BASIC is NOT in the cradled EPROM but in the ROM in the lower right corner of the PCB. My ROM 80013 is probably an revision of 80012. So: I need a copy of the 03396-80032 ROM chip. Additionally, if someone has the manual "RS232 Programming Manual", P/N 03396-90335", for the 3396 integrator. it would be great if he could scan the document and make the content available. [I have the remaining manuals and already sent scans to the HP Museum in Australia for making them available o their site. Main PCB: +----------------+ +----------------+ | PPP EPROM | | U 111 | | 27C011-200V10 | | 27C010-150V10 | | 03396-80106 | | 03396-80023 | +----------------+ +----------------+ +----------------+ +----------------+ | U 317 | | U 110 | | 27128A | | ROM | | 03396-80043 | | 03396-80013 | +----------------+ +----------------+ Opening the Case - remove transparent cover from printer compartment by pressing the hinge flaps inside - remove 2 screws close to rear edge, from top - remove 2 screws in printer compartment from top - remove keyboard: - keyboard is "hinged" at the front with three rigid noses - use a pry tool to open the 3 latches at the rear edge of the keyboard plate - lift the rear edge and pull the plate back - if you are careful, the ribbon cable can stay in place, you can thread the keyboard plate through the case opening - lift case cover upwards Thank you for reading, Martin

Compaq Smart Array 3200 Controller as a SCSI Controller

by cctalk＠ibm51xx.net

This may be a bit too new for this list but I thought what the heck - maybe one of you Compaq/DEC/HP guys would know: Is there any reason a Smart Array controller can't be used as a simple SCSI controller? I.E. No array, just using it to drive a tape library? TIA! -Ali

Sun E250, NVRAM edit? (Serial Speeds, no console, etc)

by silvercreekvalley＠yahoo.com

Hi Ethan In theory console can be set to anything but its usually 9600/8/n/1 as I?m sure you?ve tried. On some suns unplugging the serial cable is the equivalent of sending a break, so might be worth a try? Suns do require full hardware signalling on the console connection so might be worth checking.

Interested in Microport 286 System V?

by robertlipe＠gmail.com

Hi, Warren. We've spoken a few times through the decades, but a have a friend with a delightful relic of PC Unix history: the original 286 UNIX port, well before SCO with Xenix. Bela is in Mountain View, CA so he's on the wrong continent for you, but I figured you might know of an appropriate home for this. https://m.facebook.com/story.php?story_fbid=3516115585074301&id=10000027682… Thanks for all you've done to preserve UNIX.

Unisys MCP (was: Re: UniSys ClearPath OS/2200 Express?)

As an old MCP user/developer (although outside the lab), that's really interesting to me! Note: you have to register to get the software. That's apparently done by clicking on "Downloads". Then you're presented with a registration form. After submitting it, you're told you'll receive an email. Don't hold your breath. It's been 20 minutes, and no email from Unisys :( (And, no email --> no download) Stan

Unrepairable preferred It'll be going into an epoxy resin setup that someone I know is doing for a table, and I really want to get something that still LOOKS OK but is... well, just faulty and won't be restorable to service so we don't destroy any potentially usable hardware. Ideas/suggestions welcome! -- Gary G. Sparkes Jr. KB3HAG

windows program to read papertape from reader through serial port

by billdegnan＠gmail.com

Hi - I read on teraterm's forum or something like it that teraterm is not really equipped to receive an inbound papertape reader dump into an ascii file. What do those of you who have both windows and a tape reader use? RealTerm? If so, what settings? I have been wresting with this for a while...I am told my DSI NC 2400 needs hardware flow control Thanks BIll

Fan problem with DEC H7822 power supply in MicroVAX 3100

by cctalk＠beyondthepale.ie

I have a MicroVAX 3100 which has a H7822 power supply. The power supply and the machine itself mostly work (there is a problem with the SCSI interfaces but that's another story) except that the two fans in the power supply don't run. If left on for a long time, the machine gets too hot and a thermal trip operates, shutting it down. The fans are DC 12V 0.2A and if I connect them to +5V or +12V, they work fine and don't draw excessive current so there would seem to be a problem with the section of the power supply which drives the fans. Unfortunately, it's operation is not obvious and the power supply is a pig to work on. It consists of two double sided PCBs connected by short leads and having live parts on both boards making it difficult to get access to both sides of the board where the fan circuit is when the power is on. I don't have an identical working power supply to compare the faulty one to but the fan circuit looks superficially similar to the one in the H7821 which I do have working examples of so that may be a way to proceed. Does anyone have a service manual for the H7822 or H7821 or know how the fan circuit is supposed to work in these power supplies? Regards, Peter Coghlan.

Anyone out there that can read 7 track / 556 BPI tapes?

by cramcram＠gmail.com

Hi, I bumped into an old friend of mine today. We both talked about a pair of machines we worked on that no longer exist as far as we cant tell. They were both Adage machines and had the same base digital architecture. Their names are Ambilog 200 and AGT-30. The Ambilog was the predecessor to the AGT line. The AGT came in 3 flavors, AGT-10, AGT-30 and AGT-50. The 30 seems to have been the most prevalent. They were 30 bit, one's complement machines. The Ambilog had a beautiful console that used an IO Selectric. It was designed as a 2D vector graphics machine. Here's an image of the Ambilog 200: Ambilog 200 <https://d.lib.ncsu.edu/collections/catalog/ua023_024-001-bx0010-020-004#?c=…> The AGT/30 was a very advanced 3D vector machine. The XYZ signals for the display came from a 4 x 3 "hybrid" matrix multiplier which allowed for 3D imaging with Z axis depth cueing. The matrix multiplier was a 19 in rack of a dozen discrete 15 bit multiplying D to A converters. About once a year it had to be re-calibrated due to long term drift. Here's a link to an image of an AGT-30: Adage AGT-30 <https://www.google.com/url?sa=i&url=http%3A%2F%2Fwhat-when-how.com%2FTutori…> And here is it's 1.5 seconds of fame from the SciFi classic "Dark Star": AGT-30 das Blinkenlights <https://youtu.be/ocse-0bBfo8?t=3152> Anyway, it turns out he has quite a few of the source and backup tapes. Unfortunately they are 7 track 556 BPI. So the question is: is there anyone out there that can assist with either reading these tapes or (better yet) has a 7 track tape head we could buy? Our goal is to preserve this forgotten machine designed at the start of the computer graphics era. Writing a full emulator is our goal. I live in the Bay Area. Maybe those of you with connections to CHM could see if we could read the tapes on the 1401. Or maybe one of you has a 7 track driver in your junk file. All we really would need is the head and we could put it on an existing drive. As a last option, a commercial tape recovery vendor although that is probably too pricey. Thanks, Marc Howard

Motorola 12Xbug?

by cmhanson＠eschatologist.net

Does anyone know where to find Motorola 120bug or 12Xbug? I have an MVME121 but it has a third party ROM, not the typical Motorola boot ROM. (The 12Xbug manual would be handy too, of course.) -- Chris

Help identifying mystery Dataram VAX-11/750 (?) board

by derschjo＠gmail.com

Hi all -- Picked up a board advertised as a "4mb memory board" for a VAX-11/750. It's made by Dataram and I'm unsure of the model number, based on photos of it. I just noticed that rather than being a hex-height board that goes in the memory backplane, it looks like a board that goes in the main CMI backplane. It also appears to have 16mb of ECC memory on it, rather than 4mb. My thought is either (1) it's not actually for an 11/750 (in which case I'm curious what it would go into), or (2) it completely replaces the memory controller and standard memory and gives you 16mb in the 750. (Or it could be that it's something else entirely.) If anyone has any ideas or has a source of information, let me know. I put up a few pictures here: http://yahozna.dyndns.org/scratch/dataram/ Thanks as always, - Josh

Small C ver 1.00 source?

by wrcooke＠wrcooke.net

I'm trying to find source files for the very first, original, ver 1.00(?) small C compiler. I have the DDJ issue with the printed source (minus the assembly language runtime libs.) I have found all sorts of derivative works, but I haven't found files of the original version. My old eyes aren't up to typing in 13 pages of scanned copy of printed dot matrix listings. Does anyone know where a downloadable copy of these files can be found? Or have a copy they could send?

interfacing DSI NC 2400 tape reader/punch

by billdegnan＠gmail.com

Is there a trick to archiving tapes to PC using Teraterm from a DSI NC 2400 reader/punch? Or is there a best software for this? From the terminal I can ctrl+Q to cause the reader to initiate a read of a test tape but I can't capture the output of the tape through the modem port of the reader into the serial port of my PC. I tried various things with settings. I was told it uses hardware flow control. The reader is set correctly as far as I can tell. I am using 2400/8/n/1 but I have tried other settings. I get no response from the terminal inbound at all. I am using a USB to serial interface that I know works with an RS232 modem, but it may not work with the reader. If so, I'd like to know if anyone has a similar experience. It may not be straight forward and I have to make a custom cable. I will keep at it, report if I find the answers. Bill

Dilithium Press (Computer Books)

by healyzh＠avanthar.com

Out of curiosity, does anyone know anything about this publisher? They apparently existed in the late 70?s and early 80?s. They were apparently located in Beaverton, Oregon in the same business park, on Nimbus, where Norvac Electronics was. They obviously published some very strange computer books, including what looks to be a teen romance. I find myself with an embarrassingly nice little collection of the books, that my Dad apparently had. Considering I think he touched a computer twice in his life, they?re something of a mystery. Best title, ?Nailing Jelly to a Tree?, which is apparently a book on Software. The publisher sounds vaguely familiar, and I think I might have one or two other books from them in my collection. Zane

Gotek Floppy Drive Emulators in general and as RX50/RX33 replacements

by bobsmithofd＠gmail.com

Two questions, 1. If anyone is using these devices, which firmware/software do you use in the device and why did you choose it? 2/ Is anyone specifically using one as a replacement or adjunct or and RX50 et al on a Pro, pdp11, uVax, DecMate, or Pro box, and same question set as 1? Yes, i picked up one, and looking at the capabilities, documentation first, and considering reflashing the beast to give more control of formats. TIA bob smith

Microfiche reader spotted in Longmont, CO thrift store

by cruff＠ruffspot.net

If anyone along the northern Colorado Front Range is in need of a microfiche reader, it was reported to me that a Micro Design model 4010 is sitting in the Longmont Community Thrift store. My source didn't notice a price. The condition is unknown, but it appears to be reasonably intact, and a cell phone picture from the front is available if you send me a message.

CDC CYBER 170 Consoles

by ccth6600＠gmail.com

I have been working on CDC CYBER 170 mainframes between 1977 and 1988. In 2002 I wrote an open-source emulator for the CDC 6000 and CYBER series (see my website http://www.control-data.info/). In 2013 I also developed the open-source VHDL firmware emulating the console controller for these systems. The firmware runs on a Xilinx Virtex 6 FPGA on a PCI Express (PCIe) board. The off-the shelf Xilinx board carries a small custom "piggy-back" board with 4 DACs and 4 op-amps to interface to a DD60or CC545 console. This PCIe board was used by Paul Allen's Living Computer Museum (LCM) in Seattle from 2013 onward in a PC running my 6000/CYBER series emulator to drive a real DD60 console. The CC545 has a very similar interface and my emulated controller would work with it too. For many years I have been trying to find one of these vector drawn CC545 consoles to use with my emulator but I haven't been able to find one. Recently I decided to build a clone of it myself. Bitsavers has a hardware manual with schematics: http://www.bitsavers.org/pdf/cdc/cyber/cyber_170/62952600L_CYBER_170_Displa… The CC545 console achieved unusually fast deflection with an electromagnetically deflected CRT. I am trying to understand the tricks they used to get these high speeds. Part of the magic is a dual-yoke which provided gross positioning within 2 microseconds to anywhere on the screen using the first yoke (this is VERY fast) and then painted the character using a second yoke around that base position with 0.1 microsecond per stroke (this is VERY fast too). The two yokes work in an additive manner. The reason there are two yokes is that you need quite low inductivity/impedance to be able to drive the symbol vectors at 0.1 microsecond per vector with up to 24 vectors making up one character. The gross position yoke needs to create a large enough magnetic field to sweep across the entire screen so has a higher inductivity/impedance but the magnetic field has 2 microseconds to stabilise. The older DD60 console used electrostatic deflection which is much faster by its very nature. Traditional CRT oscilloscopes were all electrostatically deflected because of the speed advantage over electromagnetic deflection. The CC545 manual on Bitsavers has a good description of the circuits and schematics, but unfortunately Section 8 with the "Parts Data" has not been scanned. I really would like to know the types of transistors used in the 4 deflection amplifiers as well as the details of the dual-yoke and possibly the CRT data. It would also be very useful to see details of the design of the dual-yoke and possibly the inductivity of each of the coils. This dual-yoke is most unusual and very different from what is used in TVs, CRT monitors and even vector drawn games like Vectrex or early vector drawn Atari arcade games. Could somebody please help?
