You've obviously discovered (or knew) that MS-DOS COPY won't accept the /B switch when one of the "files" is a device. You're not the first to have this chicken-and-egg situation with Kermit; the Kermit distributions have C and FORTRAN programs to turn an EXE file into a BOO file, which can go over an ASCII link and be decoded by a smallish BASIC program called MSBPCB.BAS (there are C and Pascal version of this, too). There's a description of how it's done at http://www.ibiblio.org/pub/academic/computer-science/history/pdp-11/rsts/de… which might save you some time. -- Pete Peter Turnbull Network Manager University of York

FS / FT: SGI, RS/6000, Sun, DEC Alpha

by jkunz＠unixag-kl.fh-kl.de

Hi. I have some machines I don't need so I wan't to sell / trade them for somthing different. I have no urgent need to get rid of this machines. I will keep them warm and dry. So nobody has to be worried, this stuff will _not_ go to the dumpster. ;-) I am located in Kaiserslautern / Germany. SGI Personal Iris 4D30 (IIRC 16 MB RAM, base 8 bit GFX, no HDD) Sun Ultra 1-170 (SBus only, no RAM, no HDD) RS/6000 C10 (64 or 128 MB RAM, 2 or 3 2 GB disks) RS/6000 3BT (512 MB RAM, 4 GB disk, GXT150 GFX) RS/6000 39H (256 MB RAM, 4 GB disk, some big dual slot GFX) RS/6000 40P (??? MB RAM, 2 or 4 GB disk, P9100 GFX) AlphaServer 1000A 5/400 (192 MB RAM, 6 x 4 GB disk in internal SBB) All RS/6000 are MCA, they have a CDROM and at least one Ethernet interface. The 39H has a minor defect in the PSU. It powers up and runns perfectely. But if you switch it off for a short time it doesn't come up. You have to disconnect mains power for some hours. Then it will come up well again. The 40P doesn't run stable. Maybe it needs to be "Kreidlered". The 3BT has some additional SCSI cards, one is HVD. I need / want: UniBus Pertec tape, RL02 and SMD disk controllers for my PDP-11/34. VAX 4000-705A AlphaServer [48]x00 SGI Onyx 2 (Yes, I have dreams. ;-) If I get a VAX 4000-705A there will be a VAX 4000-400 available.) -- tsch??, Jochen Homepage: http://www.unixag-kl.fh-kl.de/~jkunz/

Reviving old hard drives

I had a couple of friends that worked at Seagate during the stiction problems. It was caused by the surfaces being too smooth. When the platter stopped rotating, the air would be squeezed out from between the two and they would become stuck together. They solved the problem on later drives by making the platters surface have a specific amount of roughness. Machinist that work with gauge blocks understand the stiction issue. When stacking the blocks they become stuck together and they have to be forced apart. Dwight

Votrax PSS Auction almost over!

by aek＠spies.com

>>I hope to see the whole thing scanned (and I want to see the scans too). >And this information is worth how much to you? I was hoping to get scans of the *ENTIRE* Votrax PSS manual -- Perhaps you are not a native English speaker. I just spent over $200 for something I was not particularly interstested in because you were whining on this mailing list about wanting the documentation. I am not going to put this information up on bitsavers for free. If you feel this is worth something to you, put up or shut up.

Looking for Larscom CupreDSU

by msokolov＠ivan.Harhan.ORG

Hi everyone and Happy New Year, This is probably OT because the piece I'm looking for is not 10 y old, however, it is an item of interest primarily to those with a passion for classic computing and seems to be absolute unobtainium, much harder to find than many older items. The CupreDSU is a unit that allows one to connect a classic router of the kind used with [F]T1 lines (in my case a MicroVAX with a DSV11 card running 4.3BSD-Quasijarus) to a Copper Mountain SDSL line. Apparently it was manufactured and sold only very briefly because it is of no use to ordinary sane people who just want to use their DSL lines like normal people do, with an Ethernet interface. It is, however, useful to crazy people like me who for non-objectively-justifiable emotional reasons refuse to use a modern DSL router with an Ethernet interface and insist on using a Quasijarus router instead, i.e., connecting the MicroVAX (via DSV11) to the SDSL line *directly*, without an intervening Ethernet. The CupreDSU is a V.35 DSU for the SDSL electrical signal and does for SDSL what typical CSUs/DSUs do for T1 and DDS lines. Copper Mountain has a page on their website listing all CPE compatible with their DSLAMs, and according to that page Larscom is the only manufacturer that ever made a simple DSU, which they called CupreDSU. All other CPE listed there are Ethernet routers or bridges. The only other unit that comes even close is the ADC Kentrox CopperSMART, which appears to be a plain DSU at first glance, but it is also too smart for me. It knows about Frame Relay frame format and has functions for tampering with the data passing through it, while I want a raw DSU that passes bits through without interpreting them in any way. So I'm running around with my tongue out looking for a Larscom CupreDSU, which apparently due to being totally useless to 99.9999% of DSL users is absolute unobtainium. So if anyone here has one they can part with, I offer $$$. If I cannot find one, the only other alternative would be to build such a DSU myself. Does anyone know anything about Copper Mountain SDSL Layer 1 electrical signal format? Has anyone ever tried to reverse-engineer a CopperEdge DSLAM or one of the routers or bridges compatible with it? Reading the manuals for various products (bridges, routers and the Larscom unit in question) I see consistent references to something called SDSL firmware, separate from the main unit firmware, which is often upgradeable. This makes me strongly suspect that all those products incorporate an SDSL Layer 1 circuit licensed from Copper Mountain, and that the SDSL firmware they are talking about is probably for a DSP used in it. The question is, how is this circuit interfaced to the rest of an a typical router/bridge product? Is this circuit implemented in separate chips and there is a TTL/CMOS-level bit-serial interface lurking in between this circuit and the rest of the router/bridge, or did they cram the entire SDSL circuit, including the DSP and flash firmware, into an ASIC together with other unrelated things? Has anyone poked inside one of those routers/bridges? TIA for any help, MS

Votrax PSS Auction almost over!

Date: Fri, 31 Dec 2004 17:11:38 -0800 (PST) From: aek(a)spies.com (Al Kossow) Subject: Re: Votrax PSS Auction almost over! To: classiccmp(a)classiccmp.org Message-ID: <20050101011138.738694D2F(a)spies.com> >>I hope to see the whole thing scanned (and I want to see the scans too). >And this information is worth how much to you? I'm working on an independent research project about the Votrax Synthesizers and their workings. For experimentation and also vintage value I purchased a Votrax PSS about a month ago from eBay, which did not include a Manual or power supply. Since then I've managed to acquire a manual, but it was the older, shorter version (the one with the 'cursive' Votrax logo on the cover). Robert Stek sent me a scan of his manual right before I got mine in the mail, and it is exactly the same as mine. I was hoping to get scans of the *ENTIRE* Votrax PSS manual (to post on one of the manuals-archive sites, since they don't seem to be available anywhere), but I realized that the shorter version of the PSS Manual doesn't include the "Operation -- Advanced Procedures" section, it only has an order form for it. (My PSS also has the older cursive logo, but it also had some sort of sticker on the front which is torn and illegible now. There was a NASA auction a few months ago where a similar PSS with an intact sticker was sold, but the sticker isn't readable from the picture.) I know the manual with that auction (and the PSS too, though its hard to see in the picture) have the newer Votrax 'V' logo on them. I contacted the seller, who sent me several scans from the manual shown with the auction, and it DOES include the "Operation -- Advanced Procedures" section! It has different page numbering throughout the manual too. So I'd like to see that version of the manual completely scanned also, as a lot of very useful information is completely left out of the shorter manual. What I'm *PERSONALLY* interested in would be to get scans from the appendix of the manual, since thats the only part which I don't already have in some form. (The seller was *very* nice, and sent me over 15 pages of scans!) But in the long run, I'd be happiest seeing the whole thing scanned and posted somewhere for future PSS owners to read. Jonathan Gevaryahu jgevaryahu_(a)t_hotmail.com lord_nightmare_(a)t_users.sf.net (replace _@t_ with @) P.S. Does anyone around here have or know where I could get a Votrax VSK or a VS6(any type) synth? I'm looking for one of those too, for experimentation.

S-100 Polymorphic Systems card questions

by dwight.elvey＠amd.com

Hi The zener is only needed if the keyboard you intend to use needs a negative rail. Normally most would need a 12 volt zener but some need a -15 volt level. You need to check the current of the keyboard to determine the right value for the resistor. As Randy states, the manual is available now. The keyboard is intended to be connected through this board and this board has a connection to one of the interrupt lines. The keyboard is to be a parallel out, 8 bits, w/ + or - strobe. It has memory mapped video with either characters ( including Greek ) or block graphics. The output is standard composite video. If you ever want to get it working, you can contact me and I can most likely help you some.
