Wanted: 8" double density floppy drive

by rescue＠hawkmountain.net

Anyone have an extra one of these ? Best would be one with simple power requirements (like the later half height versions), but I'm just looking for something I'll be able to hook up to a Kryoflux or some FDC that can handle FM and MFM for imaging 8" diskettes for archival. I'm in the states (Sharon, MA). If it is a late half height unit, I suppose international shipping would be work if I can't locate something stateside. If you have one of these, let me know what you want for it. -- Curt

free VAX 4000 VLC

by BHuntsman＠mail2.cu-portland.edu

Hi there! I picked up a VAX 4000 VLC a while back that was listed "as-is". Unfortunately, while it does power up, I could never get a console to come up on it, and I don't have multimeter/scope skills. It suffered a bit of damage on the way to me, and there's a bit of broken plastic, and the keyboard connector on the video board is broken. Otherwise, it's in decent shape. Rather than toss it though, I figured I'd offer it up here in case anyone had the time, patience, and interest to try to fix it. Free for the taking... I only ask for shipping cost. Thanks! -Ben

Cardinal Technologies ASCII KB675

by go4retro＠go4retro.com

I have an individual with a Cardinal KB675 ASCII KB on an industrial tool that has went bad. He's inquiring whether one of the projects I have (a PS/2 to ASCII converter) will work, and I can't imagine it would not, but I hesitate to say so or promise anything without any knowledge of this KB. Anyone have any information on it, or can speak to its interface? I saw this as well: http://www.galco.com/repair/Cardinal-Technologies/KB675 and will forward it onto them... > > Message > Dear Sirs.

Teleray 10E

by rescue＠hawkmountain.net

I mentioned in one of my posts about a Teleray terminal I have. I've pulled it out of storage, and it is not a TE-10 as I misremembered, but a Model 10E. No docs on this unit on bitsavers. Anyone have anything on this terminal. I know it worked in the 90s the last time I powered it on. It is in great shape. Nice little terminal (nice 70s "sci fi" kind of look). -- Curt

The last time I got paid to do VMS was just over 10 years ago. I used to get pinged about open VMS positions (usually at that same place I had recently left), but even that dried up about 6-7 years ago. It's been nearly all Linux (with a wee bit of Solaris) recently. Ten years ago, there were still open positions in the States, and few individuals left with any recent experience to fill them (that was one specific complaint from the manager that hired me - recruiters kept sending him candidates that hadn't touched VMS in 5 years or more and would have to be relocated from one coast or the other. I had 3-year-old daily experience and lived 15 minutes from the office. That clinched the job). In the past 5 years, I've heard nary a whisper of VMS in commercial circles. Not saying it isn't there somewhere, but wherever it is, they aren't posting for new hires. -ethan

FS: OpenVMS documentation, LK-series keyboards, SCSI HDDs and more

by marcogb＠xs4all.nl

Here's what I have to offer: - DEC OpenVMS V6(.3?) full, paperback, documentation set in original Digital-branded carton, all in excellent shape; - HP-branded LK463 keyboard with USB interface and PS/2- converter, in excellent and practical new condition; - DEC (and Digital-branded) LK46W-A2 with PS/2 interface, very good shape (looks great), except one 'tilting leg' is missing; - DEC ball mouse with PS/2 interface, in the same beige color as the LK46W-A2; - various old and new 68-pin and 80-pin SCA/SCA2 interface SCSI disks, both in 2?" and 3?" form factors (mostly 'short' ones, thus not the 'taller'/older types) in and of various brands/models and capacities ranging from 1 to 300 Gbytes (contact me for more information); - various old 50-pin SCSI disks (idem ditto, except the capacities range from 1 to about 4? Gbytes and some are 'taller'), contact me for more information); - DEC RRD43 external CD-ROM drive, amazingly with original documentation(!) and SCSI-type converter and cables (Digital-branded, too) available; - HP DS2100 (Disk System 2100), UltraSCSI (either U160 or U320), for 4 * 3?" SCSI disks in HP "ring"-type sleds, in excellent shape and with rack-mounting 'ears' included; - loads of SCSI cables, practically all sorts and kinds; - loads of SCSI terminators, both active and inactive, mostly LVD/SE and quite a few still even in packaging; - loads of HP disk brackets/sleds, including the HP "ring"- type in both light/beige and dark gray/black that would fit in rx1600/rx1620/rx2600/rx2620/rx4640, DS2100, etc. and the like computer/storage systems, also many non-HP sleds for more 'PC'-like systems, like IBM ("x"), Dell and what-not (ask if you're interested); - DEC Multia/UDB VX40B with 166-MHz processor and 256 Mbytes RAM, 72-Gbyte U320 2?" SCSI disk (that I shoehorned in with necessary conversion), with HP Tru64 UNIX V5.1B-4 pre-installed and lots of extras; - DEC Multia/UDB VX42B with 233-MHz processor and an unknown amount of RAM, without (working, or actually, wired PSU connector) and in 'unknown' working state and in otherwise fairly good physical condition; - original DEC advertisement material, VAX and AXP/Alpha era marketing material (brochures, whitepapers, "Digital Systems and Option Catalog" booklets from several years and more), I'll make pictures of them if there's interest for it; - several OSF/1 and Tru64 UNIX workbooks, or at least one that I could immediately find; - a bunch of DEC, Compaq and HP cables, plastics and other types of parts; - a bunch of OpenVMS and Tru64 UNIX installation media, originals; - an original CD-ROM (in jewel case) installation medium of the Sybase database software for OpenVMS AXP; - loads of memories, including PC2100 ECC-registered DDR- SDRAM (like for several HP Integrity systems, many even original and HP-branded) and the "parity" type that would fit/work in the Multia/UDB (the exact type escapes me at the moment), also the type for DEC Personal WorkStation-series and likely more (ask for more details, I will then take a closer look); - a good quantity of *OpenVMS-compatible* (in fact, also HP-UX- and IRIX-compatible) _10-Gbit_ fiber-optical (i.e. 10GBASE-SR) PCI-X ethernet NICs and also LC/LC fiber-optical cables available; - several (mostly Ultra320) SCSI HBAs, PCI or PCI-X; - HP 8-port RJ-45/UTP KVM extender hub, I'll have to check the exact type (but it should work with fairly recent RJ-45/UTP KVM equipment); - Quantum Ultrium LTO-1 SCSI tape drive, full-height, in external enclosure and with various empty data cartridges; - several, mostly Sony (and possibly rebranded), DAT40/ DDS-4 SCSI tape drives and loads of empty DDS-2, DDS-3 and DDS-4 data cartridges, also cleaning tapes. I may have forgotten to mention some things, I may add those later on. (If you suspect I made a typo somewhere, feel of course free to contact me about it.) Anyway, I plan to recycle the majority of this in about a week or two, if these items haven't been spoken for by that time. - MG

Sage IV info

by derschjo＠gmail.com

Hi all - Snagged a Sage IV machine, running p-System (IV.21) with the Modula-2 suite installed on the internal hard drive (which I believe is 20mb; I haven't disassembled the machine far enough to ID the drive and I don't have any of the hard drive utilities available on the machine to probe with). I'd like to back up the hard drive before I do anything else with this thing, especially since I don't think the Modula-2 software has been archived anywhere (if I'm incorrect in this regard do let me know). Plus there's a sweet half-finished Vampire novel on the drive that I simply must save. Anyone have any experience with these and have any backup suggestions? I'm considering writing a quick Modula-2 program to dump the drive sector-by-sector over the serial port but if there's some prior art here I'm a big fan of saving time. Incidentally -- anyone have any contact with David Erhart, the guy who runs sageandstride.org? His FTP site (which hosts a lot of the documentation, schematics & software) is currently down; I've e-mailed him to no response. (Anyone happen to have this stuff archived?) Thanks as always, Josh

by mazzinia＠tin.it

Hello, Long story short, a SGI Fuel psu MNB 060-0140-004 Rev b died with a bang and now the person who gave me the Fuel is looking at it to try to repair. He found a resistance blown (so bad that's unreadable) on the primary R25 Near the leveling capacitor on the rectifier. Any chance that someone has a datasheet or can read the value of R25 ? (good pics are also ok, I think) Thanks, Alessandro

How Often to Run Old Systems to Protect Power Supplies?

by bobvines00＠gmail.com

How often do you recommend running old computer systems & peripherals (and other old electronics too) to protect the power supplies and other components from the "escape of magic smoke" when next powered up? For instance, I've got computers, peripherals, oscilloscopes, and "home electronics" from the early to mid '70s on up to 5-10 years ago. I've only let the magic smoke escape from one systems power supply so far, but how often should they be powered up for "preventive maintenance"? I'm guessing that the older systems with linear power supplies will need an attempt at reforming the capacitors with a Variac (or equal) before starting any "preventive maintenance" power-ups. After, at least, a visual inspection of the capacitors for damage is performed. What about the systems with switch-mode power supplies? Is there an easier way than isolating or removing the capacitors before "reforming" attempts are made? Any recommendations? I suspect I'm not the only one here with old systems that haven't been powered in years. Thanks, Bob

new 6x0x board project

by LYNCHAJ＠YAHOO.COM

[note: this went out to the N8VEM mailing list. The proposed 6x0x schematic and PCB layout files are at http://n8vem-sbc.pbworks.com/w/browse/#view=ViewFolder&param=ECB%206x0x ] Hi! Sorry for the long message. I have a lot to say about a new N8VEM board project and am asking for your help. I think the 6x0x host processor, 6x0x IO mezzanine, and 6x0x ECB backplane are in need of a redesign and PCB respin. The three board "sandwich" approach has some major limitations and has led to some really weird and unnecessary complications. All the 6x0x PCBs are out so this is a great time to rethink the whole approach. Some builders and I have been discussing the topic and it dovetails nicely with some other improvements builders have been asking about. For example, it would be nice if we had a form factor that leveraged more easily stock ATX cases and power supplies. Also the ability to use 6U chassis with Eurocard backplanes (aka VME) form factor would help. Attached are notional redesign of the 6x0x board series into a single integrated board. It is still an ECB board but as a bus controller rather than as a peripheral like the 6x0x host processor. The new 6x0x board includes the dual CPU socket for 6502, 6809, and 6802 compatibility as well as all the IO from the 6x0x IO mezzanine (serial, parallel GPIO, timers, etc). As it is no longer a peripheral on the ECB bus it now includes a variant of the ParPropPort built in to provide full builder interface such as VGA display, PS/2 keyboard, SD mass storage, speaker, etc for complete standalone capability. Please review the proposed 6x0x schematic and PCB layout files and send me any changes and/or corrections. The new board is ATX and 6U chassis compatible. You can mount it in a stock ATX case and use a stock ATX power supply unmodified. Likewise with a 6U chassis. I am very interested in any discussion points on the 6x0x however please keep in mind this is an incremental step to addressing broader issues with the N8VEM collection of boards. You can still keep it out of a case altogether and set it on your workbench if you like or mount on some plywood. Assuming the new 6x0x form factor design is successful, I would like to adopt this form factor for other N8VEM boards to provide better and more functionally complete peripherals. Probably the next step would be to redesign the N8 to use the new form factor although it still remains to be seen if and how this works. We already have a notional schematic and PCB layout so the next step is to get some prototype boards. I will get four (4) prototype PCBs from Advanced Circuits as soon as the PCB completes some initial trace route optimization. Please keep in mind though the initial prototype boards will almost certainly not work as intended and will require extensive debugging, cuts and jumpers, dead-bugs, and all sorts of heinous, grisly PCB circuit modifications. As a result the initial build and test team has to be small and limited to the most experienced builders. If you recall the N8 and uPD 7220 GDC build and test phases then you'll know what I am referring too! If you have any questions or comments please feel free to ask. Thanks and have a nice day!

Research Inc. Teleray Terminal

by kylevowen＠gmail.com

Hi all, I have a couple of 3511D terminals from 1976 or so. Both can send data just fine to my PDP-8/M or my laptop, but they refuses to receive anything now. Both worked several weeks ago, though they started to get a little flakey. I probed the MC1489 in one and found that the received signal looks very nice. After that, though, I haven't been able to test much more without a schematic. Tracing it out is difficult thanks to the opaque IC sockets. I've tried to ohm out where the output from the 1489 goes to no avail, other than to pin 20 of the DB-25 connector. Why would they be sending a 5V TTL signal out the RS-232 line? Does anyone have any information on this terminal? Some images can be found in this album: http://imgur.com/a/fDVDH Thanks, Kyle

KA630 (MicroVAX II) print set available, TH50

by elson＠pico-systems.com

Trying to thin out my stuff again, I still have the MicroVAX II print set, as well as a TK50 that is a bit dirty, but probably repairable/cleanable. Also, a spare KA630-AA (M7606) CPU, as far as I know operational. Also, a KA650 with two M7621 memory boards. Anybody want to make an offer on this stuff? I also will eventually tear down the MicroVAX II that I ran for 21+ years in my home. I'll have to get an inventory of the boards. Jon

VT103

by rescue＠hawkmountain.net

I made a trek over the weekend to collect a VT103 with RX02 drive unit. With it came around 35+ 8" disks with stuff on them, and a dozen or so DECtape II tapes for the dual dectape II drives in the VT103. I have not tried powering on either unit yet. Inventory of the boards in the VT103 are: M7264-EB KDF11-F with KEV-11 with onboard 4KW MOS RAM M8047-CA 16KW RAM M8044-BB 8KW MOS RAM M8028 M8029 RX02 flopppy disk controller (18 bit DMA only) I have a set of floppies with dot matrix'd lables 1/4 through 4/4 for RT 4.0 "patched". Not sure if these are original DEC. They have DEC part numbers/etc on them, but nothing that really indicates they are DEC (no DEC branding/etc). Any idea of these are original ? Given the CPU and storage, I'd assume RT would be this boxes current limit, correct ? Is 2 8" floppy drives enough to make a sysgen'd RT with software and space to do stuff with ? Before powering up for the first time, anything I should be aware of that would be likely weak with the VT103 after years of sitting idle (attic) ? (i.e. caps in the power supply are likely to pop) How are the DECtape II drives ? Do the capstans tend to turn to goo ? They look OK visiually, though I have not touched them. Any good way to confirm if they'll hold up or break down before they eat a tape ? How best to preserve images of the 8" disks ? I understand there are parallel port RX02 emulators for the system, but nothing that I found for hooking up the RX02 drive unit to a PC for imaging. I've also read that the RX02 used a percular format (MFM sector data with FM headers as I recall). Will things like the Disc Ferret archive images if I had a more modern 8" floppy drive to use with it ? Suggestions ? Obviously if I get the system working and I had another M8029 (which I don't), I could hook up a RX02 emulator and duplicate discs from real ones to the emulator. Is that the only viable option ? How best to image the DECtape II tapes ? If the drives work, I understand they are serial, so is there any source out there for doing this under Linux/UNIX ? Or again, what I have to do this in some fashion under RT-11 and get the images off the system ? What should I look out for, clean, lubricate/etc on the RX02 before eventually trying it for the first time ? And lastly, towards the future, I understand one can add the 4 missing bits on the backplane to go from 18 bits to 22 bits, then an 11/23 cpu can be used in it. Is this the only cpu board upgrade option viable in an VT103 ? With that, I'd assume RSTS/E, TSX, RSX, RT, and old Unix would be options ? What would be the suggested hard drive options ? Will CQD-22 SCSI work on the existing CPU ? Will it work with a larger CPU with an upgraded bus within the VT103 ? I'd like to consider some sort of SCSI->ATA->flash solution for low power and put it inside the VT103 for a self contained approach. The mounts are not standard, otherwise ZIP drives or JAZ drives in place of the DECtape IIs would offer immense storage and easy switchover to other 11 OSes. Looking to understand this box more, how to bring it back to operation, and what I can do with it as is, and improve it a bit towards the future (no cutting/drilling.... any upgrades have to be able to be removed to bring it back to original. Unrelated, anyone know if the VT525 does Regis graphics ? Thanks in advance, -- Curt

The LSI-11 does not support an MMU, so ONLY UnMapped Monitors can be used. For RT-11, that means RT11SJ or RT11FB. Since you have 48 KB of memory (the maximum for RT11FB is 56 KB in any case unless you use a 4 KB IOPAGE), RT11FB will run very well. I suggest you check the board number!!!!!!! If M7264-EB is correct, then according to the field guide from Megan Gentry, you actually have a KD11 or an LSI-11. BE CAREFUL!! BDAL18-21 are used VERY differently for the LSI-11 than for the PDP-11/23, etc. Before you use a different CPU or upgrade to a 22 bit backplane, find out from someone who knows what, if anything, needs to be done. OTHERWISE, there may be a release of magic smoke (the euphemism on this list for a fatal hardware burnup!!!!!!!!!!!). On your backplane, there may be power on some or all of BDAL18-21. Since all of the VT103 terminals I have ever seen used at least an M8186 (PDP-11/23), BDAL18-21 were all UNUSED. >>I have a set of floppies with dot matrix'd lables 1/4 through 4/4 for RT 4.0 >>"patched".

If that is possible, upgrading all the way to the most recent version of RT-11 should also be possible and with 48 KB of memory, RT11FB will run well. You also have the advantage of current manuals which are available on bitsavers. Where are you located? If you are restricted to RX02 floppy media, then someone might be able to copy the needed files. >>Given the CPU and storage, I'd assume RT would be this boxes current limit, >>correct ? >> >Yes. 28KW is plenty for RT-11.

But is would be slow and cumbersome with just the dual RX02. I recommend you stick with DEC distributions for now until you obtain a hard disk drive. If you really need to perform a SYSGEN, do so under Ersatz-11 with an emulated 32 MB (or larger) emulated hard drive, then transfer all of the files back to your system. What would be your goal in performing a SYSGEN? >Sure. It'll be slow to compile FORTRAN, but fine for BASIC or MACRO-11. > > I suggest that FORTRAN IV will be OK as well. Just don't expect anything to be very fast. If you want FAST, then use the Ersatz-11 emulator. I estimate that a current 3 GHz Intel CPU will be about 500 to 1000 times faster (based on being able to run RT-11 more than 100 times as fast as a PDP-11/93). >>Before powering up for the first time, anything I should be aware of that >>would be likely weak with the VT103 after years of sitting idle (attic) ? >>(i.e. caps in the power supply are likely to pop) >> >I will defer this to others.

These emulators support VERY LARGE emulated TU-58 media and you could copy the 988 blocks (about 1/2 MB) to your emulated TU-58, then save the file to the hard drive. Just a suggestion, I have never used the TU-58 emulator myself. >>And lastly, towards the future, I understand one can add the 4 missing bits >>on the backplane to go from 18 bits to 22 bits, then an 11/23 cpu can be >>used in it. >> >Yes. > > You can use any M8186 or M8189 (PDP-11/23 CPUs) or M8192 or M8190 (J11 CPUs) in either an 18 OR 22 bit backplane. What I do NOT remember is what the 18 bit backplane requires for the M7264 to run. I seem to remember that the PDP-11/03 required power on lines BDAL18-21, so as I suggested (WARNED EMPHATICALLY ABOVE), CHECK WITH SOMEONE WHO KNOWS WHAT IS REQUIRED!!!!!!!!!!!!! >>Is this the only cpu board upgrade option viable in an VT103 ? >>With that, I'd assume RSTS/E, TSX, RSX, RT, and old Unix would be options ? >> >Perhaps someone here who has done it could comment, but I'd >want to check the current draw against what the VT103 PSU >can provide.

Other than identifying the exact points to solder the extra wires (you will need lead based solder since this is a VERY OLD backplane), it is very easy to use insulated wire wrap wire (either 28 or 30 is probably OK) and strip the insulation ONLY where the wire needs to be soldered to the backplane. If you have a 4 x 4 backplane which allows 8 dual boards, each wire needs 8 solder points. Start by stripping the insulation as far back as possible (I suggest about 2 ", but maybe Tony can elaborate) from the end if the wire and solder the first point. Then cut the insulation (WITHOUT CUTTING THE WIRE) for the exact distance needed to the second solder point and squeeze the insulation as far away from the second solder point on the wire as possible. Solder and repeat 6 more times with the first wire. If you hold the wire carefully just beyond the solder point and very gently press the bare wire to the next solder point (I suggest - Tony please comment - with flux already on the bare wire), then with the other hand heat the bare wire and below it the solder point until the solder melts, that could be quite sufficient if you immediately remove the heat and allow the joint to harden as you prevent any movement of the wire relative to the solder joint. It is probably best if you completely remove the backplane before you start. >>What would be the suggested hard drive options ? Will CQD-22 SCSI work on >>the existing CPU ?

I haven't tried running a Q22 disk >interface in a Q18 backplane, so > If you mean a CQD-220M or CQD-220TM in a 22 bit backplane, I agree. I have not ever placed a CQD-220TM in an 18 bit backplane or with a PDP-11/03. Since a CQD-220TM is probably still fairly expansive, a PDP-11/23 with at least 1 MB of memory is probably a reasonable companion for a CQD-220TM. >>I I'd like to consider some sort of SCSI->ATA->flash >>solution for low power and put it inside the VT103 for a self contained >>approach.

You can solder the wires to the board while also distributes the power to the TU-58 and solder the pins for a power plug for the 3 1/2" hard drive. At one point, I upgraded a number of VT103 systems to use an ST412 (10 MG hard disk drive) on a 3rd party MSCP controller and I mounted the ST412 (5 1/4" hard drive) just below the tube. There was just enough power for everything with that 3rd party MFM controller. The RQDX2 would have used too much power and, in any case, does not have a boot ROM which was needed with the M8186. >>Looking to understand this box more, how to bring it back to operation, and >>what I can do with it as is, and improve it a bit towards the future (no >>cutting/drilling.... any upgrades have to be able to be removed to bring it >>back to original. >> >Get it up and running RT-11 from RX02 and see about those upgrades >you were thinking about.

I have other Qbus >boxes I can do that on. > If you upgrade from an 18 bit backplane to a 22 bit backplane, I don't think removing the extra wires would be considered to bring it back to original. Since everyone has their own definition, you decide. My personal preference to have more than 256 KB of memory would outweigh any concern. Since the very first PDP-11/23 that I owned was a VT103, the opportunity to upgrade was taken VERY seriously and done as soon as I could purchase the required parts. After I received a BA23 box, I stopped using the VT103, but it remains a very important (and still very much appreciated) member of my PDP-11 systems. Jerome Fine

Documentation search

by sander.reiche＠gmail.com

Hi all, I'm currently looking for a bit of documentation. I can probably run RT-11 V03b on my 11/10, but to my surprise I cannot find a complete docset for that version of RT-11. Does anyone have it in digital form? Next to that, there's a hype going on APL (don't ask me why) and I caught the virus as well. The documentation that comes with the SIGtape providing APL/11 for RT-11 tells me (it really does) to go get (quote): "For DIGITAL software documentation order the "APL Programmer's Reference Manuel AA-5076A-TC APL-11/RSTS/E V1". THAT'S RIGHT FOLKS, WE MEAN RSTS/E. ". Anybody have AA-5076A-TC digitally? I cannot seem to find it anywhere. Thanks in advance and with kind regards, reiche

Dietz minicomputer

by cc＠informatik.uni-stuttgart.de

Hi, I'm looking for any kind of document and software for the Dietz Mincal 523 minicomputer, or anecdotes, user reports etc. I don't expect too much feedback since this is an obviously very rare German minicomputer from about 1970; it is a micro-programmed 19 bit architecture with shared microcode/core memory. But asking doesn't hurt ;-) Christian

DiscFerret: It just keeps getting better...!

by classiccmp＠philpem.me.uk

Hello, folks! Hope you all had a very merry Christmas, happy Hanukkah, or whatever you celebrated! Also, best wishes for the New Year, which will be... in around two and a quarter hours in my neck of the woods :) It's been a while since I posted anything related to DiscFerret. Rest assured, I have not been resting on my laurels (Balrog and Lord Nightmare have made certain of that!). In fact, I've just released a shiny new toy for all you DiscFerret owners... Well, two actually! Microcode Release 0026 and C-API 1.3! New in these releases...: - Microcode: - Added a clock divider to the Data Acquisition core. Now you can specify how much timing resolution you need -- 80ns (12.5MHz), 40ns (25MHz), 20ns (50MHz) or the full 10ns (100MHz). When set to 40ns, the DiscFerret matches the Kryoflux for read speed (84 tracks double-sided in one minute and 45 seconds). At full resolution, it still only takes three minutes and 25 seconds to image the same disc. - Completely rewrote the data sync-word detector. All the ripple clocks and clock-domain crossings are gone, and the data separator is FAR more reliable. The capture and lock range is about 20% of the nominal data rate (!), which is more than adequate for most disc drives. The sync word may be up to 16 bits long, and can also include "don't care" bits! - Miscellaneous fixes to the data separator configuration (it was set for a 16MHz clock, but provided with a 20MHz clock. Despite this, it still worked fine!) - C/C++ API - Support added for the new clock divider register. Files are all downloadable from the usual place -- http://www.discferret.com/ (or more specifically:) http://www.discferret.com/wiki/DiscFerret:Downloads And you can, as always, browse the source code here -- http://hg.discferret.com/ On the cards for the New Year -- - Work has started on a new, simplified API. This will make its grand d?but some time in the new year. - I'm working on improving the accuracy of the INDEX pulse storage logic. When finished, this will improve the accuracy of INDEX timing measurements to match the data timing measurements! (This is a minimum of a factor of 8 improvement over the KryoFlux analyser, and a factor of 128 improvement over the current microcode release!) Special thanks for this release are due to: Rich Thomson, Karsten Scheibler, Sarayan, Balrog, Lord_Nightmare, ... and anyone else I've forgotten! Thanks! -- Phil. classiccmp at philpem.me.uk http://www.philpem.me.uk/

Apple LC 520 edge connector pinouts?

by jules.richardson99＠gmail.com

As per subject, does anyone happen to know the system board edge connector pinouts for an Apple LC 520? I picked up a few useful boards which were destined for recycling from someone yesterday, and decided to save the Apple board too, more out of curiosity than anything (it's not obvious what machine it was from, but I'd noticed the '030). It might be fun one rainy day to try feeding it power - assuming I can find out what the power requirements* are, and assuming that the video signals (which would have gone to the built-in CRT's analog board) are something sane. [I have no VRAM module for it, but looks like it has a banks of 1MB and 4MB on the PCB, so perhaps the 1MB is for regular framebuffer, and the VRAM socket is only for expansion to allow higher resolution or color depth] * main power rails are likely possible to work out, but of course there will be soft-start and power-good type stuff to worry about. cheers Jules

FS: Cisco ASA 5505 with 1-Gbyte RAM (!), 4-Gbyte flash storage, fully licensed and documentation

by marcogb＠xs4all.nl

Not really 'classic computing' or'retroware' purely in or by itself, but it can certainly be a great addition! I have anice, compact, Cisco ASA 5505"security appliance" (read: an IOS hardware firewall)here, maximized memory (1-Gbyte, so enough for the latest firmware), 4-Gbyte fast CF storage, with a Cisco RJ-45/UTP<=>serial cable included, also the original paperback documentation and the device is fully licensed. (For any specifics, pictures and such, contact me.) It's a great device to secure and filter traffic going in and out of your collection of older systems, so you won't have to worry as much about vulnerabilities and so forth. It's located in the Netherlands. - MG

The Depraz mouse.....

by jdr_use＠bluewin.ch

Just found out that a Depraz mouse type D83/P does not necessarily has the same pinout as a Depraz mouse type D83/P. Yep, you read that right.... In fact the red-shelled D83/P has a totally different pinout than the grey-shelled D83/P. Execpt for the power, which is exactly reversed. Sigh... Luckily it does contains only common parts (7405 and 74c14). Idiots......

FS: SGI Indigo² (IP28) 175-MHz MIPS R10000 processor

by marcogb＠xs4all.nl

Is anyone looking for, or otherwise interested in, an SGI Indigo? (IP28) 175-MHz MIPS R10000 processor? It doesn't have the fan installed on it, I remember when I bought this one of the blades was broken (and about to fall off) and I tried to fix it by attempting to glue it, but it didn't work out (the plastic was too thin and delicate). Other than that, the processor works fine and was removed from a working system at the time (about a year or two ago, when I upgraded to a 195-MHz processor). I can look up specifics (like cache size, which I think is 1 or 2 Mbytes or so), show pictures and so forth, if needed/wanted. The object is located in the Netherlands. - MG

SE/30 Analog Board? (was :Re: Zombie Mac Plus)

That is the best solution for your issue. It does remind me that I have an SE/30 that needs an analog board. Does anyone have one available?

DEC PC500

by silent700＠gmail.com

Has anyone heard of/seen/possessed this machine? http://r.ebay.com/hOeqTH It looks to be the general size and shape of the VAXmate but with an in-built 5.25" drive. I am guessing it's a standalone DOS machine, while the VAXmate was a netbooter. I can't find a single thing on it via Google, except for spammer pages that list its part number and nothing else. That item's seller has _a lot_ of DEC material. Most of it is probably on Bitsavers but after a few pages I gave up. They've also got more hardware, unfortunately most of it is very yellowed and/or damaged. All of it is pricy. -- jht

DEC Boxes/systems

by useddec＠gmail.com

My part time crew is emptying one of the storage units faster than I can sort it. It's my fault, but they are burying things here now, putting me further behind in everything including emails and shipping. Feel free to bug me if you haven't heard from me in a while. The following things are now in my way and will be priced accordingly. a few BA11-N and BA11-S, which may go ups or fed ex a few rackmount BA23s a few uvax II in BA123, I hope that's the right number, rx50 upper left, space for tk and 3 rd on right one BA215 (I think) with KA670, mem, etc All can be reconfigured within reason, some have drives Several LA120 and most DEC table top printers and printer parts found about 300 more boards today, including data products. can see 3 buried gaylords and countless boxes, printers, monitors, etc prefer local pick up, Champaign Illinois area Thanks, Paul

Macintosh case signatures

by jules.richardson99＠gmail.com

Hmm, I have a pair of Mac SE's here, and was a bit surprised to find that one of them has signatures in the rear of the case, but the other one doesn't; does anyone know what dictated whether a machine had the signatures or not? (I was actually surprised to see signatures at all, I thought that went out with earlier models) Anyway, the one with signatures is a SE with a single 800K drive and 20HSC hard disk, last IC date I can see week 25 of 1988. There's also a sticker on the chassis saying July 30th 1988. The one without is a SE with dual 800K drives and a Quantum drive on a bracket (which was possibly added later), last IC date I can see being week 01 of 1988. In other words, what seems to be the later machine has them, and the earlier one doesn't. Possibly cases from different plants, where one had changed their tooling and one hadn't? Or maybe the "later" machine is actually an earlier build but has had a system board replacement (with the date sticker being the date of repair)? Curious, anyway... cheers Jules

Soviet line voltages

by derschjo＠gmail.com

I ended up with an Elektronika-85 (also known as the MS-0585)that was sold by a listmember a few weeks back. It's an uncanny clone of the Dec Pro 350/380 both inside and out. I'm just givingit a basic inspection at the moment and I'd like to test the power supply, I'm just unsure what voltages / frequencies it wants and there are no labels anywhere indicating what those might be. My research on the 'net indicates that it's likely to be 220/240V (in which case I'll need to get astep-up transformer), but I was wondering if anyone here had any first-hand experience with this sort of thing. Thanks as always, Josh
