OT : What is this Monitor

by lgwalker＠look.ca

Don't quite know where else to ask this, my apologies for the OT. I recently acquired an EZC m. sm483c monitor with a DB-9 socket ( sorry I've forgotten Tony D.'s correct designation) Since it was manufactured in Jun 98 it's unlikely to be an EGA. The company seems to be no longer in business and I could find little on it. EZC appears to be a company that made items for the vision- impaired so I expect this is some kind of high-definition monitor. It powers up OK but I don't want to try it on one of my EGA cards or similar 9-pin boxes lest the magic smoke escapes. Anyone with any info/suggestions ? ciao larry Reply to: lgwalker(a)look.ca

CP/M BIOS setup

by ajp166＠bellatlantic.net

From: Richard Erlacher <richard(a)idcomm.com> >For some time, I've pondered what it might take to divine the various format >features from a CP/M boot disk. It seems to me that if one has a bootable >disk, it has to have sufficient information on the boot tracks to allow one >to find a copy of the BDOS, which, so long as it's the right version of >CP/M, should disclose the details of what formatting has been used for those The bdos can't tell you much other than it's version. >tracks.

Then you need to know the disk layout, things like what side/sector numbering was used. For example I've seen two sided media where sector one occured on both sides and where identically formatted, also I've seen side one as 1 thru 9 and side two as 10 through 17... It is possible to devine all that from a bootable disk (I have a few that would never give you that as the core bios is not on the disk at all) but it's a lot of processing and at last count there were some 80 formats for 5.25media alone. >Have you ever run into a utility that handles this? I'd think someone would >have done this by now. Yes, Media Master, Uniform, Multidisk, Eset are a few I use and they all work from tables and have expectations of a bios having a standard configureation so they can "drive" the bios. I also use a modular bios that runs on a slave cpu for the S100 crate and dropping in different drive parameters is straightforward. I tend to treat devices as interchangeable peices by using a abstraction layer. To me the BDOS calls the BIOS and the BIOS if it needs to calls a device driver. One common misconception is the BDOS calls a FDC (simplification). It doesnt and that why the BDOS called the jump table at the start of the BIOS. >Another item I've wanted for some time to automate is the setup of a hard >disk BIOS. Since it's dependent not so much on CP/M quirks but often more >on decisions made on the basis of folklore, I thought it might be >interesting to examine the process as a candidate for automation. The answer is yes it;s doable and it's not worth it from where I sit. One reason, I have the tools needed and there are plenty of freeware out there if I dont. Me, I use my kaypro and my s100 crate (3.5, 5.25 and 8") for this and a copy of multidisk (table driven) and a version of Eset, used to hand feed parameters to the parameters for oddballs. In the general scale of things these do the job well and are more than enough. Some things deserve a simple solution. Allison

ASCI u68 System X computer

by rigdonj＠intellistar.net

Does anyone know anything about the computer above? They appear to be educational single board computers. A strip along the frond edge, lists a number of commands to set breakpoints, jump in memory, examine memory, etc. I found a pile of them at an auction preview. They're single board computers that are mounted in a wooden boxs that measures roughly 10" x 12" x 2". The box has a smoke colored plastic lid that's hinged in the back. When it's closed, everything is covered except for a 3 x 4 keypad. The CPU board appears to use the Motorola EXOR-bus and has a Motorola 6800 CPU. There is a smaller card on the RH side that has the keypad and six digit seven segment LED display. The ICs are dated 1979 and 1980. These appear to be part of a system. I found several other boxs that were also made by ASCI. One of them has a micro-cassette drive. Another is a switch box that switchs between a printer, punch, etc. Another larger box has relays and a bunch of terminal strips on it. It appears that it's meant to be controlled from the CPU box and can operate a good number of external devices. I need to know what they are before Saturday. Joe

The SKEW however may not be used in the SECTRAN call at all! Often the skew translate is a table but it can be calculated and for DD the SECTRAN call is applied at the logical sector level and doesn't apply well for double density who have sector sizes larger than one logical sector. So skew in that case will likely be burried in the raw read/write routine. Or possibly even at the logical sector level inside the the physical sector. So wome things are not guarenteed and also not easily found. >The Multidisk and Eset that I have are not for this purpose. They want to >be passed the information that I'm suggesting could be extracted.

Since we >KNOW and RECOGNIZE the BDOS, shouldn't it be possible to find its beginning, BDOS is not part of the CP/M file system! It's in the boot tracks. >paramters from the system BIOS and verifying them against another known file >e.g. PIP.COM, should provide the necessary information about the directory >and data areas of the diskette. Isn't that so? You would be forced to do that and huristically that will be a PITA! PIP is in the file system whereas BDOS is out on the boot tracks. the boot tracks in the CCS case is SSSD and the system tracks can be DSDD! The bios entries for DPH, DPB do not say if the disk is DSDD or even if it's floppy. It will tell you how many logical sectors per track, If skew is used. If directory is checked, allocation size and the size of the area used ofr data storage. You will have to figure out from that a lot of things that are variable and can still end up as the same answer. >> >Another item I've wanted for some time to automate is the setup of a hard >> >disk BIOS.

Teltek, Konan and a few others did that. A better way is to provide slots that can be filled with an address of the driver(s). The reason for the difficulty is the wide assortment of controllers and the varied protocals to talk to them. If it was always IDE or SCSI it would be simpler. >Well, I don't see hand-feeding a set of parameters that one has to determine >by guessing on the basis of lots of conflicting folklore as particularly >easy. Authors who wrote about the process e.g. Laird and Cortesi seemed to No folklore. There are detailed tables out there for every drive and disk going if one care to look.

Both of the authors I Optimal ones for hard disk in the timeframe they wrote in was simple. hard disks are FAST and Z80s (pre 1990) are NOT. No amount of optimization is possible. Actually if you have banked memory caching is the solution as it steps neatly around the problems. FYI: the problem is that CP/M does a lot of realatively small transfer with lots of references to the directory. the true limiter to performance is not data rate but latency (mostly from shuffling the head). When Laird wrote a fast drive was a Quantum D540(31mb MFM 5.25 FH) with a average latency of around 30mS. >is in hand, it's easy, certainly, but what should one do, given a known >bootable but otherwise undefined boot diskette? The reality of the data >present on a boot diskette defines all the parameters necessary to recreate >it, doesn't it? No. the boot tracks are always written by a specialized utility like SYSGEN (which is not generic code) that is always system specific. >I get emails from people all the time, asking about how to build a boot >diskette for a system they can't boot because they don't have a BIOS on the >diskette for the I/O ports they use. Most of those I converse with with that set of questions have no sources to work from and find 8080 or Z80 asm code scary to terrifying. Often they dont know the ports in use nor what they mean. Rare is the one with Docs for their system at the time the question is launched. They often think it's just like a PC where dos boots on all if the disk fits. >Likewise, I get frequent questions >about how to formulate an optimal configuration for a hard disk. While it Like Laird said and I'll say _optimal_ for what? I"d never use the word optimal. Again, expereince most want a drop in replacement like a PC. Most do not code at that level or dont wish to try. Many dont have docs needed. So what they want is not optimal, just something that works. >may not be a terrible thing, it is something many people, including myself, >though I've done it several times, find daunting. In the absence of a >rigorous method it's hard to find peace at the end of the task because so >many less-than optimal solutions will work quite well. How's a person to >determine what's best? Lesse, I have five systems with hard disks all were added later two with code supplied. I find peace with the fact that they work and are reliable. Only one have I applied rigorous and experimental methods to the extreme to see what was possible and effective... Occams razor won most often. Here it is: hard disks and performance. Assume nothing about the hard disk used rare is the old drive/controller that can really help you. DMA or a seperate processor will help if the CPU is loaded or memory is short. Caching at the track or cylinder level with a LRU method really helps if you have space (64-128k is good). You will cache(call it host buffer if you like) anyway as most hard disk have sector sizes larger than 128 bytes requireing deblocking. Caching the directory seperate from the data area cache really pays as it saves head thrashing. Achieve the above or subset with direct and efficient code. I've tried this using a IDE drive (still working the code out) and most decent over 100mb drive have caching (quantum PRO AT series does). use it as it isolates you from things like skew and all. If you using a an old SA4000, forget all this as making it work is three quarters the battle. Allison

FUBAR and DW780

This register is called, not suprisingly, the > > > > Failed UniBus Address Register This is certainly serendipitous, but not the origin of the epithet. FUBAR dates at least to WWII; I read that in an article about tech terms that we tend to think are recent inventions but which have been around for a rather long time. For example, while Grace Murray Hopper is credited with finding an actual moth wedged in a relay in the Eniac 1 (thus "bug" in the system), the term "bug" has been found in the writings of Thomas Edison, referring to a defect in a design. "HAM", referring to amateur radio operators, is a 19th-century invention; it was previously used to describe self-taught telegraph operators. And "to hack" is supposedly an old Yiddish phrase that refers to the making of furniture with an axe (and although a different usage, "hack" has referred to taxis since they were horse-drawn in the early 1800s). And on and on... regards, -dq

Fix for Telnet bug in VMS TCPIP V5.0

by cmcmanis＠mcmanis.com

Hello everyone, I realize that VMS 7.2 doesn't meet the 10 year rule but the hardware it is running on does :-) To "close the loop" on this one, Zane pointed me to a recent fix posted by Compaq on their support site for TCPIP V5.0A. This update fixes a bunch of different bugs. My bug was the Telnet server went berserk when I tried to connect to it. The problem is in the WILL/WANT negotiation that goes on gets screwed and ends up looping infinitely. You can fix this by installing the TCPIP$TNDRIVER.EXE and TCPIP$TELNET.EXE images from the fix on top of an existing TCPIP 5.0 installation. --Chuck

Old Agfa Scanners

by ainsinga＠infomation.com

I have 2 old (maybe they fit your definition of classic, maybe not) b&w or grayscale scanners -- Agfa Focus ('Focus S 800 GS') and Agfa Focus II -- which I'd like to get rid of very soon and are available for the first, best offer. (0 is a perfectly good offer from a non-profit group.) They could be picked up in Andover, MA or Nashua, NH. I don't really want to pack and ship them; they're heavy and I'm not sure I still have the carriage locking instructions (but I'll look). They worked when I last used them but I haven't powered them up in a half-dozen or so years, since some release of OmniPage Pro dropped support for them. They have Centronics 50-pin SCSI connectors. I used to have a 68k MacOS driver for them, which Agfa would give away, but their DOS/Windows? drivers were integrated into some software that they sold (and I never got).

IBM System/360 model 30 doc.

by Henk.J.Stegeman＠is.shell.com

Hi, I was lucky to buy a very nice operator panel of an old IBM S/360 model 30. I am now trying to rebuild this IBM S/360 model 30 (using this panel as a base) with modern TTL, EEPROM's IC's etc. With the current information I have, I was able to reconstruct about 50-60% of it's logic diagrams. I am still searching for ANY customer engineering documentation of this old IBM system, specially the small CE reference booklet for the model 30 and the Functional Maintenance Manual. Anyone who can help me ??? I already have a copy of the 'Theory of Operations' and micro-code flowcharts manual. Regards, Henk Stegeman, IBM collector Phone: ++31-70-303 4513

Rewiring VAX 6000 for single-phase AC?

by mrbill＠mrbill.net

Anybody have instructions/details on how to re-wire a VAX 6000's three-phase 115V AC power supply for 220V single phase? The only thing I've got so far with any information is this: http://www.decvax.org/vax6000/power.txt However, I cant find any way to get ahold of the author of the text, who mentions: "I you get a 6000 (or similar) machine let me know. I have worked out a very elegant way to do the above mod which entails no soldering , no disconnecting of joints etc , and can be put back to factory standard in about 30 secs." What I need, is that information - but the email is at least 4 years old and the addresses no longer current. I've got a VAX 6000-410 here that I'd love to at least fire up and run some diags on, and I cant do that till it will run on 220V power....

VCF 4.0 is in the books ...

by cmcmanis＠mcmanis.com

Well, the dust has settled and I'm trying to re-store all the stuff I dragged out for VCF 4.0... I had a great time, placed a couple of VAXes into very nice homes (and Zane will be happy they both had VMS installed on them) and generally enjoyed meeting everyone again and talking old hardware. This year the exhibit/market space was shared by the California Extreme pinball show/thing and it was, unfortunately, a bit loud. However it was most likely the largest number of 8 and 16 bit micros operating in a single space in all of California! There was a great set of talks this year, I'm hoping to get tapes of the ones I missed. Overall, it was fun but exhausting. Public thanks go to Sellam for "producing" this event, it is really great. --Chuck

Also other defined commands terminate with a call to who. The status line also has current directory and account. the switch box was a LQPX2-SW and MMJ to DB/P25 cabling. Allison

Don't ask me how to set it up, though; it was over 10 years ago and on the other side of the continent, but I had one providing print service using reverse LAT and I convinced another one to provide access to an HP3000/70 via a serial connection to an ATP port on the 3000. You do need a MOP server from which the DECserver can download its software. -Frank McConnell

WANTED: (Xerox) ViewPoint Scavenger software

by yoda＠isr.ist.utl.pt

I'd like to bring a Xerox DayBreak (6085) workstation back to life, but I'm unable to do it because it requires a so called VP Scavenging software. Can anyone send me an electronic version of the disk/tape image containing such software? If anyone has at least Xerox 6085 software, in any form, PLEASE contact me: maybe we could arrange a way to convert it to an electronic format. Furthermore, if anyone has any bootable software for such a beast, please contact me.

I was trying to find the order number for the OpenVMS V7.2-1/Alpha update, and came across the following little tidbit. With all the VMS traffic here the last few days I thought a few people might enjoy this. I'm sure a lot of you have seen this before.

OSI model 600 find

by dcoward＠pressstart.com

It's been a while since I have picked-up any _digital_ computers, but I just could not resist this. I found someone selling a Ohio Scientific Model 600 on eBay, and when I went to check was it sold for, I discovered that no one wanted to bid the $20 minimum bid. http://cgi.ebay.com/aw-cgi/eBayISAPI.dll?MfcISAPICommand=ViewItem&item=37585 7886 So I asked for a picture of the computer to make sure it wasn't just a baggie full of spare parts. http://www.best.com/~dcoward/osi600.jpg I paid for it and it arrived today. There seems to be only one empty dip socket that looks like it should not be empty. It looks like the key caps for the numbers were removed on purpose. Without taking it apart, I can see one ROM labeled "BASIC 3", and two EPROMS labeled "BASIC 4 modified 12/21/81" and "SYN 600 MOD". I found one web site that also calls this a SuperBoard II. The main board says: "Ohio Scientific Model 600 CPU @1978 Rev B" The large daughter board says: "@1980 AARDVARK". And it contains a MC6821 PIA. The small daughter board contains three 2716s labeled "REV 94 I", "REV 94 II", and "REV 94 III". All in all it looks to be in very good condition, but powering this up is going to have to wait. My wife wants my current projects off the dinner table and the analog flight simulator and the paper tape punches out of the dining room. --Doug =================================================== Doug Coward dcoward(a)pressstart.com (work) Sr Software Engineer mranalog(a)home.com (home) Press Start Inc. http://www.pressstart.com Sunnyvale,CA Visit the new Analog Computer Museum and History Center at http://www.best.com/~dcoward/analog ===================================================

You might be a VMS Bigot if.....

by mmcfadden＠cmh.edu

Real programmers use DCL and FORTRAN. I used to work for a large engineering firm which used VAXes and VT220's for everything. Mostly we used 11/750's and 11/780's for CAD/CAM. We tried PRO 350's and 380's for engineering applications. I originally programmed structural design of pipe hangers on a PRO 350. For word processing they purchased AT&T 6300's with 10MB HardCards to replace all of the typewriters. All of a sudden everybody could create a document and send it out. File copies were never created or lost. Some people used WordPerfect, MultiMate, WordStar, and IBM DisplayWrite 3. Fonts, margins, and layout all went crazy. How would you like to pay 4 million dollars for a set of Coal fired power plant manuals and end up with a mess? We standardized on IBM DisplayWrite 3 and I was given the task of capturing all of the printing and filing it. We used a MicroVAX II to drive Xerox 2700 laser printers on each floor. Every time you printed we captured and archived a copy. I then created a FORTRAN77 program on the VAX to translate EBCDIC IBM DisplayWrite3 documents to ASCII and then print them. We also included the ability to take HPGL plot files and scale them to fit into an area in a document. We also added special symbols, foreign characters and logos. Engineering companies only believe in FORTRAN. We had a bad experience with a programmer who wrote lots of code in "C" and then left. Most of my support time was spend proving that my software was not at fault when the PC's were not working, the network was hosed or the printer was out of paper. Computer viruses were not a problem, only game players, and wierd spell checkers. I still have my copies of the FORTRAN version of a word processor print spooling application.

Hmm.. "You have the complete VMS docset on display in your living room." Only one docs set? I have 2 complete ones and several incomplete ones... "You keep wanting Digital to produce "Visual DCL"" Eh? I'd imagine that would look really weird on my LA120... "You still have a VAX architecture manual" Which one would you like? 80-81, 82, 86, or the big expanded 8.5" x 11" one? And which rev of the instruction set reference do you prefer? "You need a mouse with three buttons and the middle button is useful" Mouse? Whazzat? "You believe a computer might handle more than one user at a time" Maybe, but they have to bring their own chair and their own terminal "The concept of a blue screen of death is foreign to you" Well, in theory, I suppose I could make a text page entirely composed of the word "death" and somehow get a blue ribbon made for the LA120.. but where does the screen part come in? "You think that a command line interface is better than a GUI" A GUI? Was someone drinking pop around the computer again? "You reboot your desktop station once every 15 months (and only because a tornado caused a city-wide power blackout)" Hah, my station is being used *AS* a desktop "You know you can find out how to use a command by typing help and get it" I think I'll just look it up in the doc set, that'd be a lot of printing _________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com.

Zilog S8000 available in the UK

Got my PDP-11/34! Now what?

by pdp-11＠swbell.net

I recently got a PDP-11/34A, with 2 RK05 drives, about 10 packs with RSTS/E and maybe RSX-11M (not sure about what else). The main cabinet is almost completely full of cards that I know almost nothing about. I powered up the CPU, and it appears to work. I have a lot of manuals also. My question is: What should I do first? I have no idea how to clean this stuff. Right now I really want to know what I should do in preperation for setting everything up. Thanks, Owen

It's a standard 32768 x 8 CMOS EPROM, 70ns access time. I have the data sheet if you really need it. Pinout is: Vpp 1 28 Vdd A12 2 27 A14 A7 3 26 A13 A6 4 25 A8 A5 5 24 A9 A4 6 23 A11 A3 7 22 ~OE A2 8 21 A10 A1 9 20 ~CE A0 10 19 D7 D0 11 18 D6 D1 12 17 D5 D2 13 16 D4 GND 14 15 D3 Like many devices of its time, it has an electronic signature, though it's unlikely your circuit checks that. Anyway, the signature is obtained by applying normal read voltage to all pins, except you apply 12V to A9. Then with A0 at logic 1, you get the manufacturer code 0x98 and with A0=0 you get device code 0x45. -- Pete Peter Turnbull Dept. of Computer Science University of York

Login on VMS

by ncherry＠home.net

What are some of the default logins under VMS. Yes this is the first time I've played with the beast. BTW, how long does it take for DECUS to allow membership? I'm dying to get the CD's which I can't until the membership is approved. And lastly can I pop on a 3rd part SCSI drive on the uVax II? -- Linux Home Automation Neil Cherry ncherry(a)home.net http://members.home.net/ncherry (Text only) http://meltingpot.fortunecity.com/lightsey/52 (Graphics) http://linuxha.sourceforge.net/ (SourceForge)

Looking for VMEbus module manuals

by cfandt＠netsync.net

I periodically poll the list to see if anyone has the following manuals that I'm looking for. Been a long time, so here goes again :-) : I have a couple of Mizar VMEbus Video boards, model 7710. Has anybody an operator's/technical manual? Either an original or decent xerographic copy will do. Has anybody written an OS-9/68K ver. 2.3 or 2.4 driver for this thing? These are 1989 vintage. I'm also looking for the following Motorola VMEbus Module manuals: ** MVME 236-1,2,3 (Publication number MVME 236-1 Dx ), DRAM memory module (x = version or edition number. I'll take any version.) ** MVME 133-1 (Publication number MVME 133-1 Dx ), Processor module ** Support Docs manual for this processor: SIMVME133-1 ** MVME134bug (Publication number MVME134bug Dx ), debugger manual for '134 processor module ** Support Documentation (schematics, etc.) for an MVME147S which is publication number SIMVME147S. Already have the manual. ** Xycom XVME 682 -which is a VMEbus PC/AT (Intel 286) processor module ** I'm also looking for Xycom catalogs and any tech documentation from back in the mid-80's. Thanks for your help!
