PALCE and PEEL programming algorithms

by d235j.1＠gmail.com

Hi all, After a ton of digging, I found information about PALCE programming in what looks like a senior project to build a PLD programmer. Unfortunately it's completely in Indonesian, but fortunately it's easy enough to figure out what they're doing and Google Translate. In case anyone is interested, here you go: https://dl.dropbox.com/s/g1r5bgg6ae1nank/PLD%20programming.zip The original source was here: http://dewey.petra.ac.id/jiunkpe_dg_16353.html Annoyingly the redirect you to a viewer that supplies compressed jpegs unless they detect googlebot (I think they do this by IP). Fortunately google caches the PDFs. On a similar note, does anyone have the PEEL programming algorithms? ICT used to have them available here: http://web.archive.org/web/20020827040802/http://ictpld.com/programverify/i… However ICT is long gone. I am missing most of those files. The ones I have can be downloaded here: https:/dl.dropbox.com/s/h93l0cyta4l67ky/PEEL%20programming%20specs%20partial.zip?dl=1 Thanks! --David

CP/M clones & compatible OSes

Which makes me wonder > how common "almost CP/M" variants were... That's a really interesting question, actually, I would say. [Does a bit of Googling] There were, it seems, various Torch Z80 addons for the BBC Micro. The only one I saw or used was a Disk Pack: http://acorn.chriswhy.co.uk/docs/Torch/Torch_Z80DiscPack.pdf There was a time, when I was about 13 or 14, when I thought that this was about *the* most powerful and desirable computer setup I'd ever seen or heard of. ;?) What I had not appreciated until now was that Torch's version of CP/M was a special one, which ran from ROM. That is apparently why they called it CPN instead. There was also a standalone 2nd processor, no disk drives: http://acorn.chriswhy.co.uk/8bit_Upgrades/Torch_Z802ndproc.html There's a user manual for a CPN system here: http://acorn.chriswhy.co.uk/docs/Torch/Torch_ZDPUG.pdf It contains a little non-technical info: ? the TORCH CPN operating system, (a 16K ROM containing a CP/M compatible "look alike") ? ? INTRODUCTION The TORCH CPN operating system which is a CP/M "look alike" has much more flexibility than conventional CP/M. It has more "built in" commands and is easier to use. The most significant advantage of the TORCH CPN operating system, is that it is stored in ROM (Read Only Memory) rather than on disc. This means that on "power up" the TORCH disc pack and BBC micro are automatically ready to accept instructions typed in at the keyboard. ? Another CP/M compatible OS I was aware of was Pro-DOS for the MGT SAM Coup?: http://www.samcoupe-pro-dos.co.uk/whatisprodos.html ? What is Pro-DOS? Pro-DOS could be thought of as a Disk Operating System (DOS), However, it is more than this, it is a full Operating System that Provides compatibility with CP/M 2.2. In simple terms this means that a whole world of software that was designed to run under CP/M 2.2. will now run on the SAM Coup?. Pro-DOS uses the same Disk format as the Amstrad PCW 8256 and, as a result, it can read disks from this machine direct, this also Means that there is a vast range of software already available from sources such as Public Domain libraries. ? I hadn't realised it was by virus writer Chris "The Black Baron" Pile, who was imprisoned for writing Queeg, SMEG and Pathogen: http://en.wikipedia.org/wiki/Chris_Pile_(programmer) It is an admitted reverse-engineered effort as you can find from this interesting review, complete with an account of nostalgia-destroying 8-bit compatibility problems: http://www.samcoupe-pro-dos.co.uk/pdreview.html As for the Tatung, I've found very little info on XTal DOS, apart from something calling it " a compatible but beefed-up version of CP/M called Xtal DOS." http://www.tuicool.com/articles/myEBvq Anyone got more?

Looking for VAXstation 3100/M76 RAM (MS44-AA)

by polemon＠gmail.com

Hello, this is my first post to this ml, so please bear with me... I've become something of an DEC enthusiast since I pulled a VT220 out of a dumpster of my university. I have two VAXstations by now, one of those is a VAXstation 3100/M76 and it has always been a project to max-out the RAM and get a new hard drive for it. Getting that stuff on Ebay is (a) increadibly expensive and (b) mostly not possible at all, because they only sell to companies. I need RAM modules (at least four of them), hard drives, those weird flat screws with their rubbery-plastic gromits, and possibly a terminator for the external SCSI bus. I got spare RTCs (DS1387), it was no problem getting the drop-in replacements for that from Maxim. I live in Germany, there haven't been too many DEC users here, DEC was mostly USA. I'll pay for shipping and basically any price you ask, except it's those comical prices on ebay (4000 USD for a VAXstation main board with CPU, no RAM, no case, no drives; or 60 USD for a single RAM module). Please, if you're willing to send some of your stuff over to Old Europe, please let me know... Cheers, --polemon

CFFA3000 and Apple III

by wheagy＠gmail.com

Great, thanks. I DL'd the book and will read through it (your second link). The III operates somewhat differently than I expected. Sounds like my first step is to get SOS on a floppy so I can test the III and make sure there are no disk drive issues before proceeding to the CFFA. Based on my experience with the CFFA and the Apple II, I was thinking it was going to be a bit more straightforward. Thanks for the info. Win --- Unlike the II, which is relatively easy to configure to boot to any (bootable) storage device in nearly any slot, the Apple III tries to boot only from the internal floppy drive, and as Eric pointed out, you'd have to roll your own ROM to change that behavior. The CFFA3000 works nicely in the III, but you lose the Drive ][ emulation capability and you can't boot directly to it. In the Apple III, everything is seen as a device and requires a driver that SOS loads as it boots in order to be accessible to the system during operation. You can't (easily) boot directly to the CFFA because SOS requires a driver to be able to recognize it. Fortunately, SOS is close enough to ProDOS that you can use the CFFA in an Apple II to create floppies from the images you downloaded. I'd suggest reading this PDF for more on how the III works: http;//apple2scans.net/scans/manuals/3rd.party/OMHGYA3.pdf It's the Osborne McGraw Hill Guide To Your Apply III. Pay special attention to Chapters 3 and 4. LMK if you have any questions about all this. - Mike

They have oilite (porous sintered bronze) bearings mounted in a cotton oil wick. You can add a lot of oil to the wick material and let it soak in, then clean and oil the bearing and shaft when reassembling. By the time the surface oil is used up, new oil from the wick should soak through. Jon

I used both monitors at the same time with software I wrote and --for example-- the Microsoft Quick C compiler, which has the standard output through the Indigenious card and the compiler messages on the mono monitor.

CFFA3000and Apple III

by wheagy＠gmail.com

Mike, I wasn't sure how the driver worked and couldn't find any docs. I assumed it worked in a way similar to the firmware updates...i.e. put the driver in the root of the CF card. Apparently there is more to it. Do you have a pointer to config docs for the driver? I have no floppy disk software at all for the Apple III+. Only .dsk images I downloaded online, so I was hoping to use the CFFA3000 to run the III and perhaps make a few disks if the drive is working. So you're saying that the CFFA3000 in the Apple III is different than in the Apple II. In the II, I don't need any floppy disk software at all and can boot and run from the CFFA....which is good because most of my floppy drives for the II are intermittent at best. I'm not sure of the condition of the floppy drive in the Apple III+. For the Apple III, are you saying that I cannot completely dispose of the use of the floppy drive? Thanks, Win -------- When you say, "tried the CFFA Apple III driver," what exactly do you mean? The driver needs to be configured properly before the III+ will recognize the card. Also, what do you mean when you say you have no floppy software? None at all? As is true of any Apple III, the III+ will only boot from a floppy disk in the internal 5.25" drive, and you will need at least an SOS floppy with the SCP to configure the driver and run the partitioning program. - Mike

CFFA3000 and Apple III

by wheagy＠gmail.com

Anyone have experience with the CFFA3000 in an Apple III+? I have one that I've been using successfully in an Apple IIe, but have had no luck getting it to work in the Apple III. I set switch 7 on, and tried the CFFA Apple III driver, although I'm not sure exactly how that is supposed to work. I have no floppy software for the Apple III+ and am not 100% sure it is functioning properly. Any way to test the III+ without software or the CFFA3000? Thanks, Win wheagy at gmail.com

IBM hermaphroditic TR connectors

by sales＠elecplus.com

I have an entire case of adapters, made by Energy Transformation Systems, Inc. I called their tech support this morning, and was told that these were made for Token Ring connections, using IBM Type 1 or Type A cables? There are 2 different PN: EB-TRT-I has impedance matching, uses pins 3,6 and 5,4 EA-DATA-U does not have impedance matching, also uses pins 3,6 and 5,4 These have female RJ45 on one end. Apparently they are used to connect to a MAU? They look like these http://www.cuc.eu/en/li/conrj/rjembase/879700.html But use pins 3,6 and 5,4. Anybody trying to resurrect any old TR stuff? I confess, these are way beyond what I have any knowledge of!

IBM Displaywriter software?

by colineby＠isallthat.com

Al, I'm away for the holidays, but could have a rummage at TNMoC when I return. My next day at Bletchley won't be until the 12th. But do nag me if you don't hear back. I know we have at least one system, but its in storage. It would likely have arrived with some media. The media would have been directed off into the archive section.

Access to RSTS/E IOPAGE Registers

by jhfinedp3k＠compsys.to

I require some help with a program which may be of interest to other hobby users. The program is: SHOW EMULATOR or SHOWEM and runs under: (a) RT-11 both UnMapped and Mapped Monitors (b) TSX-Plus (c) RUST both RUST/SJ and RUST/XM (d) RSTS/E (e) RTEM-11 The current Emulators which are detected and displayed are SimH, Ersatz-11 and V11. If anyone knows of any other PDP-11 emulators which can also be included, that would be of great interest, especially if access to that emulator for testing is possible. I have asked for help in the past about this and the only other PDP-11 emulator which runs RT-11 compatible programs is Charon which unfortunately no longer seems to be available or even running. If anyone can help expand the list, it would be appreciated!!! Unfortunately, for (d) and (e), I do not have any information on how to access the IOPAGE registers since SHOWEM requires access to SR0 (177572) and SR1 (177574) in addition to the PSW (177776). I do not believe that RTEM-11 will ever allow a User program to gain access to the IOPAGE registers, however, RSTS/E may allow such access. Does anyone who is reading this post know if access to the IOPAGE registers is possible under RSTS/E for a program running in RT-11 compatibility' mode? And do you also know how it is done? If there is no solution, then I will make to current SHOWEM available to any hobby users who are interested. Otherwise, I would prefer to delay until the RSTS/E solution is implemented. Jerome Fine

Spacewar hardware?

by wgungfu＠gmail.com

Hoping some of the people here can help, I'm trying to compile a listing of hardware that versions of the Spacewar code were ported to after the PDP-1 during the 1960s. There was the PDP-6 version which was done at Stanford SAIL, and there were the PDP-7 and 8 versions which appeared in the DECUS catalog in the early 70s (which means they could have technically been done in the very late 60s), and the early 70s PDP-10 version (which was just a port of the PDP-6 version). Is anyone aware of any non DEC hardware it was ported to in the 60s? I haven't been able to find any concrete evidence that it was on anything other than DEC hardware in the 60s. Thanks! -- Marty

VAX 7700 CPUs, CI cables

by tshoppa＠wmata.com

Jochen writes: > I suspect CI cables are just ordinary 50 Ohm coax, but heavily > overspeced in best DEC tradition. ;-) Dave writes: > I agree (now) that they're most likely 50-ohm, but that particular > coax is anything but ordinary. ;) I'm sure they over-specced it like crazy. OK I found some hanks (chopped up from computer room removal) of old blue "thick" CI cable. I was actually gonna take it home and use it for some recabling of my radio station anyway when this subject came up on cctalk. Externally it is 0.4" like many RG-8 and RG-213 types. Internally the center conductor is 11AWG, silver plated solid copper. Yep, silver plated. The dielectric is 0.238" diameter polyethelyne foam. Again, a little smaller diameter than usual for RG-8 types, but I think in ratio with the inner conductor being smaller and the properties of foamed poly, gives 50 ohm impedance. Then, the amazing thing is what's outside the dielectric. There is a layer of foil, a THICK layer of braid, then another layer of foil, then another THICK layer of braid. I don't think I've ever seen a RG-8 type coax with 4 layer shielding. Most RG-213 types have a single thinner layer (and some have foil). I don't think the braid is silver plated, I think it's just tinned, may test that out later. If you wanted to put crimp-on N or UHF connectors onto this stuff, the funny dielectric diameter might cause some heartache, as could the extra thickness of the double braids. I have some hanks of "reddish-orange" DEC Thicknet Ethernet cables too, will check out what's inside them. I seem to recall them being solid polyethelyne dielectric but it's been more than a decade since I cut into any. Tim N3QE

Backing up a usb device sure but as Cindy pointed out its likely a poor backup media itself. Some friends and I all had 64mb flash drives back when they were new. We all lost our copies of some source code we had been using it for (portable coding drive so we could use each others systems and have our progress). Left a sore spot despite them being nice for quick trips or transferring files.

Practical Peripherals ProClock software? (Cindy Croxton Electronics Plus)

by wheagy＠gmail.com

Thanks. However, as you mention, this is a software package that is different than the software that came with the ProClock. It looks like this Comm software supports the ProClock, but does not provide the functionality of the original software. Also, trying to unpack this package, gets me into some odd circular exercise. It goes through two or three iterations of different package archive formats and ends up back at the original package. Any other leads to the Practical Peripherals ProClock software?

I was just looking at some of the old CI cables in the computer room floor. This is all bought-from-DEC stuff from early 1990's. The long ones are typically blue and labeled "12 AWG". They look a lot like RG-8/213 types. There are some skinny jumper cables on the CI panel internals that look to be a much skinnier kind of coax, also blue, looks like RG-174. In the "real world" I am much more likely to see LMR-400 or Belden 9913 specified today, than the RG-type specifications. Tim.

Western Digital My Book World Blue Rings "NAS" controller uses

by saquinn624＠aol.com

Recently came into posession of a WD "Blue Rings" NAS setup. I've rapidly come to the conclusion that it really isn't very good as a NAS, and doesn't even do what it's supposed to (I can't even get SSH to stay up or reliable connections from computers). It has a ARM-based board with an Oxford OXE800, VIA Ethernet, onboard USB, provisions for a serial port (provided I supply a level converter to go to RS-232 from the supposedly "standard" 3.3V to a real standard). The big downside is the BGA RAM chip with only 32MB. I guess it's probably in the junker category since there really isn't any way I can expand the RAM (1 BGA 256Mb DDR chip, no extra pads), but I thought I'd check because I've been interested in the Pi for a bit and then this dropped into my lap - any thing that can be done usefully with this HW?

In the market for hard disk drive for a PDP-8/m

by steve＠tronola.com

Hi Folks, I have been making good progress restoring a PDP-8/m and would like to buy a vintage hard drive and controller for it. Anyone know where I might find those? An RK05 or Diablo-31 drive would be nice. Will also need an RK8E controller board set. Have had some near misses: A Diablo-31 was up on eBay but it turns out that it's missing a head. Found an RK05 listed for sale on a fellow's site. After I agreed to buy it, haven't been able to get a reply, though. Located the controller listed for sale at another company site. The phone system takes messages but they haven't been returned (so far). Email bounces. Hmmm. Please let me know if you know of any possibilities. Thanks, Steve steve at tronola.com http://www.tronola.com/

The apostrophes (or quotations marks) should be around the entire filename, not just the part before the .dsk extension.

It's true, a DD: controller with no working units isn't very useful! E11 doesn't give an error message though, since it doesn't want to be picky about the order of the ASSIGN TT and MOUNT DD commands. For all it knows you were just about to attach files/etc. to DDA.

Osborne 1 Video Jumper

by silent700＠gmail.com

That's what I'll call it, since I don't know the correct term Osborne used. It's the plastic plug with pins that jumper the external video card-edge port on an Osborne 1 portable. Without it, the Osborne either goes into external video-only mode or, according to one doc I read, it will damage the hardware. One of my O1 machines is missing this part. Does anyone either have a spare one or know of any plans out there to build your own? -j -- silent700.blogspot.com Retrocomputing and collecting in the Chicago area: http://chiclassiccomp.org

Left a sore spot despite > them being nice for quick trips or transferring files. I'm still using my 256 and 512MB flash drives. But you have a point; the consumer flash USB drives are not known for their robustness. When customers ask to have data returned on USB flash, I balk a bit, and insist on sending along a CD or DVD with the flash--and then hang onto the data for at least 30 days. Just like floppies, storage environment and handling means a lot. If you're used to carrying a USB drive around in your pocket along with your keys, you should probably have a backup of that data somewhere. I mostly find pen drives useful for sneakernet and substitutes for CD ROMs on systems that lack drives. A useful comparison between SLC and MLC flash: http://www.supertalent.com/datasheets/SLC_vs_MLC%20whitepaper.pdf Speaking for myself, I have data backed up in several places, one of them being off-site in a vault, against the day that we have a sudden 300m rise in sea level. :) --Chuck

BETACAM or DVC-PRO... but all that is going away in favor or memory storage devices. Big concern.. as with tape I shoot injest the tape into the edit bay. toss tape on storage shelf and have the orig. saved on tape and .... the edited version can also be saved back to tape as well as saved on the network attached storage units.
