DOS application in WinXP

by bobcaar＠softhome.net

Don't forget bochs (http://bochs.sourceforge.net/). T.H.x. Devon -----------------Original Message-------------------------- Message: 2 Date: Tue, 8 Jun 2004 13:17:13 -0400 From: chris <cb(a)mythtech.net> Subject: DOS application in WinXP To: "Classic Computer" <cctalk(a)classiccmp.org> Message-ID: <S.0000344787(a)mythtech.net> Content-Type: text/plain; charset="US-ASCII" I have an old legacy DOS application that I need to run on new Win XP hardware for the next few months. The problem is, I've been told it won't run under XP's DOS Shell. I'm curious what others have used as solutions to run non NT kernel friendly DOS applications in such an environment. I'm thinking about something like Virtual PC to run a regular DOS 6.2.2 install inside it, but I have no idea if that will actually work. Plus I need to do this on up to 5 machines and buying 5 copies of VPC at the new Microsoft pricing may break the bank (Connectix used to have an OS free version for something like $50... MS now charges $130 for the base price). It looks like VMWare is going to be the same problem with pricing. So does anyone have any other recommended solutions? I'd like this to be as transparent to the users as possible (they currently run the software in a DOS session under Win95, so the closest I can come to that functionality, the better). -chris <http://www.mythtech.net>

age limits for classic computers

by melamy＠earthlink.net

set an age limit only (make it 15 or 20 years). It is quite fair to have someone email in and say they are trying to get old hardware running. There is no reason (other than personal) to restrict the list to topics as long as they do not include windows, PCs, DOS, or LINUX. It can be quite a challenge to get an old pc running as is ANY S100 based system. I have done both and I am quite willing to help anyone try and resolve issues on any machine I have experience with. If you see a mesage that you can help on, then great. If you don't, then file it away or delete it. I really don't recall seeing any messages on here that were inappropriate for a vintage forum. If someone outside finds the list and emails a question that is for something newer, then delete it or respond with COURTESY directing them someplace else. The discussion here over the topic has wasted substantialy more bandwidth then the few emails that come here that don't need to. best regards, Steve Thatcher

OT: EBay UK search hanging

by bobcaar＠softhome.net

I believe there's an option in Opera's Preferences > Network...Synchronous DNS. Disabling this should allow other sessions to continue to function. I'd also check the privacy tab and remove any cookie restrictions. I've had a similar problem on a University network with flaky DNS servers. Seems the servers would be unreachable at the moment Opera tried to connect and it choked. DNS was usually reachable again by the time I ran nslookup. My solution was to set up a local caching DNS server. This was with Opera 6.05, and it didn't happen that often, but happened on any site. I've also seen no responce from ebay when attempting to "View sellers other items" and assumed it was their problem. Never had the problems with Opera 5.12, but, it wasn't used on that network for very long. T.H.x. Devon -----------------Original Message-------------------------- Message: 35 Date: Thu, 17 Jun 2004 16:08:18 +0000 From: Jules Richardson <julesrichardsonuk(a)yahoo.co.uk> Subject: OT: EBay UK search hanging To: "General Discussion: On-Topic and Off-Topic Posts" <cctalk(a)classiccmp.org> Message-ID: <1087488498.29729.127.camel(a)weka.localdomain> Content-Type: text/plain Knowing that there's a few EBay users on the list who also know how to fix modern software... :-) On the rare occasions that I do actually bother to search EBay for anything classic computer related I quite often find that hitting the search submit button just hangs, with the browser (Opera under Linux in my case) sitting there saying "Waiting for DNS confirmation of cookie domain(s)". If I open another browser window at this point and then try and go to any other site it'll just sit there with the same message. If I close the browser and come back later it's fine. Very frustrating. Anyone else see this or know what causes it? I've *only* seen it happen trying to do an Ebay search, never with any other website - but it's been this way for months. Whilst it's hung like this in the browser I can do DNS lookups from the shell fine, so it's not a DNS problem or a local configuration problem. I assume Opera happens to use shared DNS lookup code and for some reason something to do with EBay's search *sometimes* makes it hang. Presumably others might be able to shed some light on this, or at least confim / deny that they've seen similar problems with EBay UK from different platforms and browsers... cheers Jules

Each can separately be specified before manufacture as active high or active low. Some vendors also allowed a choice on pin 20, either a chip select or a power-down/output-enable (different timing, different effect on power consumption). Also, a 2364 is an 8K ROM, but I expect you worked that out. Check what the TRS80 expects the active level to be on each of those pins (I'd guess active low), and that the programmer is doing the same. -- Pete Peter Turnbull Network Manager University of York

First of all, the mailing list won't send attachments, yet the report you got says the worm was in an attachment which was therefore removed. Secondly, they say the mail came "From: Classiccmp <classiccmp(a)classiccmp.org>" The mailing list never sends a header like that. The mail currently comes with an envelope "From" (no colon) of "cctalk-bounces(a)classiccmp.org" which contains no other name, and always claims to be "From:" (header "From:", with a colon) the original poster. What your ISP has reported on apeears to have had headers forged by the sender, and didn't come from the list. It may have come from some listmember's own machine, or at least an infected machine with "classiccmp(a)classiccmp.org" in an addressbook, but not the list. -- Pete Peter Turnbull Network Manager University of York

TRS80 Model 1 Level II ROMs

by witchy＠binarydinosaurs.co.uk

Folks, I've borrowed a universal device reader/programmer (MQP Pinmaster 48) and I'm trying to dump the ROMs from my dead TRS80. It claims to be able to read anything because of its completely configurable design (with an appropriate adapter for non-DIP style packaging) and I've already dumped some EEPROMS. However, it doesn't like either of the TRS80 chips (NEC 4K marked as 2332 and 2364) nor the ROMs on my Tangerine Microtan 65 TUGBOARD (4K roms again I think). This thing knows about over 6500 different *ROMs so maybe there's an equivalent name I can feed it to see if I can read these ROMs? Is there anyone with a TRS80 to hand who can tell me what ROMs theirs contains?

It came with a 2040 dual drive floppy disk and the IEEE interface cable. It is pretty rough looking and according to the friend, was in the former owners garage for quite some time.

Depends on the OS, but I believe DOS does so, for floppies at least, unless you use a third party driver. However, I thought one of the points of disabling an onboard device was to allow you to use one on an additional card (other reasons exist, eg preventing startup errors if you have removed floppies for security). I think I've solved the problem, insofar as I've found a combination of settings that works. I decided to make a list of the all possible permutations of relevant links on the ISA controllers and enable/disable/auto settings in the BIOS, work methodically through them, and write down the results. Mainly because I couldn't remember exactly what perms produced which problems last night! One combination of disabling the onboard controller, using a particular card (WDAT-240), having both floppies on that card, worked. Odd, because it was an obvious one that I was sure I'd tried before; perhaps I did one BIOS reset too few or something. I've not tested single density yet. And I'm not sure about reading/formatting/writing DD disks in the HD 5.25" drive. But it's well after 1am here, and I've run out of time again... > Please feel free to contact me off list if you want to discuss this further. > I do not think there are any "simple" answers [although someone else may > have an idea, which is why I am publicly responding].

The idea was to make most use of bandwidth with the technology of the early 1980s. Most of the data went from a central host to a terminal; what went back was mostly typed (page numbers, data entry fields, email), and few people regularly exceed 7 cps. There were special ports running normal symmetric 1200 half duplex and full duplex for "Information Providers" on a machine called Duke, but ordinary users didn't have access to Duke, or those ports. Data available included train and airline timetables, news, weather, lots of microcomputer stuff including "telesoftware", and all sorts of other things. There were quite a few other viewdata services besides Prestel. Some large businesses used viewdata, a few bulletin boards did, the Open University, some banks, and it was widely used by travel agents -- there was a special system run by a consortium for clearing holiday bookings. Derivatives included the French Minitel service, Germany's Bildschirmtext, and Canada had something too. The last commercial viewdata system I know of (Bank of Scotland HOBS service) finally closed last month (though it may still be running for special purposes).

IBM cassette tapes.

by henk.stegeman＠shell.com

Hi, Does anyone have technical information of the IBM cassette tapes used to load diagnostic programs in systems like the IBM System/7, IBM System/3 and the original IBM PC 5150 ? I am looking for the used frequencies (fsk), the data speed, the format, etc etc. Thanks for all your replies. Regards Henk Stegeman IBM S/7 restorer. http://www.anysystems.nl/system7.html

Rumor has it that David V. Corbin may have mentioned these words: > >Fair warning, the following message contains the ratings of a single >individual.

While I completely agree that there are significant *problems* with >both the hardware and (Windoze) software, I do believe that the more extreme >views are off base. *Everything* extreme is off-base to someone (quite often to a large installed base of someones!) That's human nature. (BTW, I'm not denigrating or disagreeing with what you stated -- I'm reinforcing it.) >IF the computer industry had remained with a large number of completely >different hardware/software environments which required trained operators >for even the most basic operations, then computing would not have become a >household commodity.

Noper -- look at game consoles.

I bought a 386SX16 clone with 2x memory, 2x HD, better video, better monitor (which was actually OEMmed by IBM anyway, believe it or not) at .5x the price.) That's why Goatway, Hewlett Putrid & Hell computers are king, not IBM. (Compaq used to be king... where are they now?)

It was an $1800 Nintendo. When I wanted to do *real* work, I sparked up my CoCo, as I could do more work in less time under OS-9. In 512K, sans HD, on a <2Mhz CPU, I could run a telecommunication software in one window, my spreadsheet in a second, word processor in a 3rd, Basic09 in a fourth, keep one window just at the prompt in case I needed it, and *still* had room for a 200K RamDrive.

'cause BABT made it so difficult (and ludicrously expensive) to get approval. I built one that did ringback in hardware, so we could tell whether it was a BBS call or a real person (only had one phone line). For those who've not come across this usage of "ringback", it means a system where the caller hangs up after the first ring, then immediately redials. The modem only responds if the first ring is short enough, and the second follows after a minimum (but still within a maximum) time. -- Pete Peter Turnbull Network Manager University of York

LPS (Digital PrintServer) questions

akb+lists.cctech(a)imap1.mirror.to (Andrew K. Bressen) wrote: > [incredible wealth of great useful info] Andrew, thank you very much for such a detailed answer packed with actual information! Earlier today, though, I sent someone a check for an HP LaserJet 4Si, so in all likelihood I'll be using that as my printer. I worked with those before and I love its engine and the way it's built, it's a great printer, and it can be equipped with a duplexer, which is extremely important for me. Since I'm a ClassicCmp'er, my printing consists mostly of specs, manuals and datasheets, and I need duplex for that. Though 4Si has only a parallel port on the base unit and is usually equipped with a JetDirect Ethernet MIO card, I have found that there exists an MIO parallel/serial card and an HP printer parts dealer is willing to sell me one. If I equip my 4Si with that card and with the PostScript SIMM, I could use it as a pure serial PostScript printer and pretend that it's a DEC LN03R. (I would also want to disable PCL and make it PS-only. HP doesn't really want you to be able to do it, but it can be set to PostScript personality in the menu. It doesn't disable PJL commands and those can still throw it back into PCL, but blocking the ESC character in the UNIX daemon/filter driving it will stop it.) Oh well, at least I'm glad I've found the MIO card for it with a serial port, so I won't have to connect it to Ethernet (in fact I'll remove the JetDirect card and put it in the closet out of my sight as soon as I get it). It's just awful, a protocol kitchen sink. But I may still some day get to play with an LPS, so I have saved your information-packed message for that day. Thanks again! MS

LPS (Digital PrintServer) questions

by msokolov＠ivan.Harhan.ORG

Hi everyone, In my search for what would be the best laser printer for me, I'm currently thinking about DEC LPS17, aka Digital PrintServer 17. A DEC dealer close to me is willing to sell me one for a reasonable price, and it seems like a really cool printer: just like the LPS40/20/32 monsters, but fits on a tabletop. Like all Digital PrintServers, it has a built-in VAX CPU running the PostScript interpreter. However, the firmware image for this VAX, containing the PS interpreter and everything else, does not reside in ROM but is instead down-line loaded on powerup over Ethernet, I presume via MOP. So it needs a MOP server on the network serving its firmware image. I can set up a MOP server, but I don't have the LPS firmware image. So here comes my first question to the list: does anyone have an LPS firmware image or is one publicly available on some archive site? DEC docs seem to imply that the firmware is the same for all LPS'es, is this true or not? I need an image that can run on LPS17 as that's the only LPS I can get. Second question. It is my understanding that once an LPS has booted its firmware, it becomes an independent node on the network accepting print jobs from anywhere on the network. Is this true or not? The protocols it speaks are DECnet and TCP/IP, right? If so, how does it obtain its DECnet and IP addresses? And if I want only one of the two, how do I configure it? Does it down-line load a configuration file from the MOP server along with the firmware image specifying DECnet and IP addresses? What is the format of this file? Third question. It is my understanding that the protocol spoken over TCP/IP is extremely simple: no LPR/LPD or anything like that, just a simple TCP port, you connect to it and everything sent to that TCP port goes to the PostScript interpreter's %stdin, and this port is 170. Is my understanding correct? If so, that's perfect, that's exactly what I want, I don't want it to do any spooling or other lpd-level intelligence, I want my 4.3BSD server to do all that, with a raw PostScript over Ethernet connection to the LPS. Fourth question. Is this PostScript-over-Ethernet connection on TCP port 170 binary clean, or is 0x04 (^D) interpreted as end of one PS job and beginning of the next? In other words, does my lpd on the 4.3BSD host driving it need to send a 0x04 between print jobs or should it close the TCP connection and reopen it instead? Fifth question. Is there any access control mechanism by which LPS firmware can be configured to accept connections only from certain sources, or will it always accept connections (and print jobs) from the entire Universe? TIA for any help, MS

Raidion LTX SCSI to SCSI raid system

by haefele＠mchsi.com

Morning All, I've pulled an old Raidion LTX SCSI RAID out of the closet in hopes of using it to backup a small server (SS20) and need some help getting it running again. For example, is replacing the drives a simple swap? The existing ones are Micropolis 3243's but 2 of the four are dead and I'd like to replace them with 4 Seagate 9.1GB narrow drives that are handy. The company appears moribund (www.raidionsystems.com). The online links to manuals are dead and email to the tech support address is returned as undeliverable. Phone calls to Tech Support get voicemail but no return call. Web searching leads to old product reviews, the company homepage, and not much else that's useful. Appreciate any leads to manuals or other documentation. TIA for your help, Doug

Cool 4004 based calculator

by dwight.elvey＠amd.com

Hi I thought I'd mention that I've written a simulator for the 4004 in the environment of a SIM-4. One could adapt it to most any hardware environment. It is written in Forth so it can be quite flexible for someone that knows Forth. If anyone is interested, I can dig it up. With a little time to refamiliarize myself with the code, I can help connect up I/O. It runs under FPC on a DOS PC platform. There is a simple assembler and disassembler as well. For someone wanting to do a 4004 project, it can be quite useful at debugging code and hardware concepts. Dwight

AMC/AMD Z-8000 Multibus pictures

by dwight.elvey＠amd.com

Hi Joe Al Kossow has schematics for this board. I don't recall which ones were which but one of boards ( with a little bit of modifications ) could have CP/M-8000 brought up on it. If you want to try this with one of your intel floppy cards, I'd try to help you. I can compile the code on my Olivetti M20. It is mostly just getting the BIOS done and a little fiddle faddle with the addressing.
