Although the SCSI to IDE/SD project is going slowly I did get about 20 PCBs earlier this year. So far we've gotten some builds underway and at least one builder has gotten the board to run Zapple as a debug monitor as a "proof of life". The project is quite a ways and is nearly complete. All it needs is some community involvement to push it to completion. In particular, it needs verification of the IDE, SD, and SCSI interfaces. Then it will need some firmware to handle the conversion. The main advantage of the project is that it is completely open and free. If there is sufficient interest, I will order another batch of PCBs or try to get those builders with incomplete PCBs to swap them out. In my opinion, this project is nearly complete and the shortest path to a working SCSI to IDE/SD converter. All it needs is some TLC and push from the community. As per the usual N8VEM guidelines this board uses all commonly available parts and is designed to be simple to assemble using basic tools. Please help finish this project. I sincerely think it will be valuable for years to come and it would be nice to discuss an actual converter during this frequent topic on CCTALK. Thanks and have a nice day! Andrew Lynch PS, I recognise the microcontroller/FPGA/CPLD approach is valid but they never seem to get off the drawing board. http://www.vintage-computer.com/vcforum/showthread.php?22906-SCSI-1-to-from… http://www.vintage-computer.com/vcforum/showthread.php?25989-Another-round-… http://n8vem-sbc.pbworks.com/w/browse/#view=ViewFolder&param=MINI%20SCSI%20…

russian PDP-11 like K1801BM2 CPU Startup reading w/o address?

by holm＠freibergnet.de

I want to play with a russian K1801BM2 CPU (K1801VM2). My russian from the school is very very rusty and so I have problems to understand what's going on with this CPU while startup. There is some "besadresnoe tschtanie", a read from the bus w/o sending out an address before w/o active SYNC. It is right, that this read is building the upper 8 bits from the start address in the rom area with Systemu Mode (Halt Mode) = 1? Can anyone please confirm this? BTW: how is this external register to be done in HW? Does anyone know if there are schematics of SBCs existing w/o special support ICs like The K1801VP1-55 or so? Kind Regards and thanks in advance, Holm -- Technik Service u.

SCSI hard drives of large form factors

by michael.99.thompson＠gmail.com

>Here's something I was thinking about the other day. I *know* for a fact that SCSI interface hard drives existed with 8" platters. I've never seen one, however. Does anyone know of any specific model numbers, or have any product information or pictures of such devices? I just looked in my collection of 8" drives. I have two 8" Imprimis/CDC 97201-12G PA8P1A ST81236N Sabre drives with the original style SCSI connectors on the back. There are manuals for the drive on Bitsavers at: http://www.bitsavers.org/pdf/cdc/discs/sabre/83325700N_PA8xx_736-1230mb_Par…, and http://www.bitsavers.org/pdf/cdc/discs/sabre/83325720F_PA8xx_736-1230mb_Mai…. The manuals say that the drives are 1.2G, 512 byte/sector drives with an HP SCSI differential interface. I can post pictures if you are interested. -- Michael Thompson

Looking for Vaxstation 3100 model 30 RAM expansion

by derschjo＠mail.msu.edu

I know I kind of touched on this in my earlier diagnostic query, but I thought I'd send out a more obvious request: Anyone have a memory expansion for a Vaxstation 3100 (model 30) they're willing to part with? Something 8MB or larger would be wonderful. I have a wide variety of DEC (and other) hardware to trade. Thanks as always, Josh

Storing cables

by ard＠p850ug1.demon.co.uk

I suspect many of use have this sort of problem, and I'd be interested in hearing any solutions to it. Moat classic computers have various little bits that go with them, in particular cables and connector adaptors. In some cases these are specific to one particular type of machine (e.g. the user prot adaptor for the Acor Cabridge Workstation), others are rather more generic (the same cassette lead fits all TRS-80 M1, M3, M4 and M100 machins, along with the IBM 5150), and still others are totally generic (HPIB cables, 'kettle leads', etc). I find storing thes parts, partircularly the 'somewhat generic' ones is a problem, and I can never find what I need. You cna't categorise them by machine (becase, for example, a TRS-80 M1 RS232 cable is specific to that machine (it plugs into an esdge conenctor on the EI), the pritner cable also fits the M3 and M4 machines, the cassette lead also fits the IBM PC), you vcan;'t realy do it by function (a DBd25-DB25 lead could be used for several purposes, not only RS232), and so on. Any ideas? I am getting fed up with having to re-make a cable which I know I made a couple years earlier, but for a different machine, and which I now can't find. -tony

Archiving Xebec S1410 / S1410A controlled ST-506 drives

by glen.slick＠gmail.com

As a follow up to Richard's question, does anyone have any experience archiving an Xebec S1410 / S1410A SASI controlled drive from a relatively modern system? If the SASI controller doesn't support the standard SCSI Inquiry and Read Capacity commands I wouldn't expect that you could simply connect it to a SCSI host controller on a Linux box and "dd" the drive contents to a disk image file. -Glen

Need: Intel "ISIS-II" development stuff for PC (DOS)

by hachti＠hachti.de

Hello everybody, I came across some MCS-48 SW project which I have to get into active maintenance again. I have assembly source and listings. And some DOS batch files wich run commands like C:\ISIS\ASM80\HEXOBJ. And there are strange .CSD files which seem to contain some kind of build rules similar to a makefile. In the listings there's mentioned an ISIS-II ASM48 assembler. And an ISIS-II linker as well. I *have* to get that stuff up and working again. What I assume: - ISIS-II is an Intel Intellec's OS. - The Tools from ISIS-II have been ported to MS-DOS but still call themselves "ISIS-II" in the listings they produce. Am I right? Does anybody have the software? Heeeelp, I'm lost! It would be very nice if one of this list could help me out. Any input welcome! Kind regards, Philipp

Interpreting Vaxstation 3100 memory error

by derschjo＠mail.msu.edu

Hi all -- Picked up a Vaxstation 3100 today at the SRCS meeting. There is some minor corrosion on the memory and motherboard PCBs, some due to prolonged exposure to moisture, and some due to a leaking clock battery. I've cleaned up the corrosion and it doesn't appear to have done any serious damage. At POST it identifies itself as a KA42-A, which I believe makes it a Model 30. I'm getting error messages from the POST and I'm unsure how to interpret them -- the manuals have not been 100% clear. Here's what I get: KA42-A V1.3 F...E...D...C...B...A...9...8...7...6...5...4...3_..2_..1?.. ? E 0040 0000.0005 ? C 0080 0000.4001 ? B 0010 000C.0081 ?? 1 00C0 0011.700E The (E) error I expect since there's no clock battery. The (C) is also expected since I don't have a keyboard/mouse plugged in (just using the serial console). Similarly, (1) is also expected since I don't currently have the ethernet interface hooked up to anything. (B) is what's confusing me -- my understanding is that a single question mark indicates a "soft" error, described in the manual thus: "Usually, a question mark (?) in the power-up summary indicates a soft error and the system may be usable without replacing any FRUs." OK. What does that mean for memory, and how do I interpret the error code? I know that the "000C" part indicates the amount of memory installed -- what does "0081" mean in this context, and should I be concerned? For further reference, "test 50" gives the following for memory: ? MEM 000C.0081 00400000 The machine does boot (VMS 6.0 off of two very noisy 104MB drives) and it seems to work OK, though I haven't stressed it much yet. Any suggestions here would be much appreciated. Thanks! Josh

VHDL PDP11

by sytsezelf＠gmail.com

Today, 11-11-11, seems like a nice day to announce the availability of yet another PDP-11 implementation in VHDL. I have created a website for my project, PDP2011 ? a re-creation of the well known series of PDP-11 computer systems in VHDL. After nearly four years of work, the project is almost finished; you can run a complete Unibus PDP-11 system with console, disks and other peripherals on a simple low cost FPGA development board. Original operating system software, like V5-V7 versions of Unix and BSD 2.11 work. I would like to invite you to come to http://pdp2011.sytse.net/<http://www.google.com/url?sa=D&q=http://pdp2011.sytse.net/&usg=AFQjCNHsCke6…> Regards Sytse

RSTS > V9.6??

by tshoppa＠wmata.com

Ignore the half-baked stuff. Fully baked seems to still be in progress. (I think Buck Henry was responsible for that line in The Graduate). Progress is very slow and what progress there is, isn't really due to any of my efforts (don't have nearly enough time to play with -11's anymore) but to others. Apache here is doing weird-ass stuff and serving up random alphabetical URL's as stuff that just happens to be in various public_html directories on my servers (apparently sometimes from other virtual domains...???) but which was never intended to be public in that sense. My fault for not understanding what Apache is doing.

RSTS > V9.6??

by oe5ewl＠gmail.com

Good evening to all DEC-Enthusiasts, stumbling around the internet and my own archive I wondered about the RSTS/E Distributions later than 9.6. I'd like to play with one of the last versions but nothing seems to be available. Somewhere I had read about licensing issues and the Mentec Discussion here. Does anyone know more of the current RSTS/E Licensing status? Or even has a distribution/documentation scanned? Any help with this questions would be greatly appreciated!

Rhino Mark III Robot Arm Controller Schematic

by wheagy＠gmail.com

Hi, Does anyone have a schematic for the Rhino Mark III Controller? I acquired a Rhino robot arm and the B motor encoder channel seems to not be working properly and I'd like to try to isolate which parts of the controller board are unique to the B channel. Alternatively, if there are any Rhino experts that could help point me in the right direction, that would also be appreciated. I think I've isolated it to a problem with the controller and not the motor/encoder or the teach pendant. Using a scope, the output from the B channel is very different than the other 7 channels. Thanks...Win

Assuming this is an MMJ socket, you just need to loop DSR to DTR (ie the two outer pins), RXD to TXD and the two grounds in the middle to each other. If any of the memory is on an expansion board, try removing it and repeating the test to see if the problem is on the system board. (I've had some battery corrosion problems in a VS3100. It doesn't look too severe but test B seems to fail in the middle and go back to the start, repeating over and over. I must get around to making a better attempt to clean it and check the traces.)
