ISO Integrated Solutions 4.3bsd binary distrib 4.0 or later

by aek＠spies.com

I've slowly been working through the box of carts that came with the ISI system that I just picked up from Erik Klein, but there doesn't appear to be a complete binary distribution tape set in the pile. An image or physical cart of a version from '88 or later (4.x or 5.x) would be helpful in trying to get the system going again. Just to get it saved on line somewhere, the format of the cartridges is a little tricky in that ISI tape controllers simulate variable blocking on QIC cartridges by appending 512 bytes of data in front of the actual data blocks. The first few bytes are all that matter for example: A1FE 0001 0002 2800 0014 is a magic number, file number, block number, and block length (10240 bytes)

Web forums are not friendly to some browsers. They're also slow. Mail delivery is indeed push, not pull; by the time it gets to local delivery reading is just opening a local file, which is rather different than downloading a page on a server at the same time as umpteen other people. And it's a damned sight easier to search, sort and filter a mailbox (local, or IMAP) than a web page. I'm with Cameron, Sellam, and Jules. And probably a few other people who wouldn't want to use web technology because they have to be online at the time they are reading, all the time they're reading.

RT11 sysgen and disk partitions

by gordonjcp＠gjcp.net

OK, next load of questions. I've been trying to create a "virgin" system from the install media I have. I have so far successfully sysgenned and built RT11 v5.0, and installed it on an RL02. Great. However, the version that boots off one of the hard disks built into the PDP allows me to access four partitions in total - DU0: to DU3: - but my own version only has DU0: (same as normal) and DU1: (same as DU3: in the version of RT11 installed on the hard disk). If I say "SET DU2: disk=0, part=1" then I can see my "old" DU1: as DU2:, and so on. What do I need to change to get it to come up like this? It doesn't appear to be a load of "SET" commands in the STARTS.COM file. Gordon.

Big list of floppy disk formats?

by dm561＠torfree.net

From: Jules Richardson <julesrichardsonuk at yahoo.co.uk> Subject: Big list of floppy disk formats? Does such a thing exist? It'd be nice to have an online resource of all the different floppy disk formats used by different machines. Yes, that's one huge list, and would likely never be complete - but as I haven't come across an attempt at all so far, it'd be better than hunting around for the data when needed. I'd be happy to collate stuff if it's thought to be a good idea - I could make it available online too (although maybe one of the recognised repositories such as bitsavers would bea better place) Data can be fed into the futurekeep project as and when necessary, as it's something that'll be needed there too one day. thoughts? J. ---------------------------------------- You probably already know this, but 22disk's cpmdisks.def has a lengthy list of at least CP/M format details; good starting point.

Amiga Mouse & list datapoint for Jay...

by zmerch＠30below.com

Anyone have an Amiga Mouse (for use on a 4000T) for sale? It doesn't need to be pretty, but it does need to work. I checked ePay, but most are in Brittania where shipping would be a bear, and the few that remains are "parts" or bundles... Unforch, I'm in a bit of a hurry for this - it rides on getting the rest of the 4000T (which the owners have ever-so-quickly gotten in a big hurry to get rid of, but need to remove personal data first, and don't have the keyboard or mouse! :-/ ) I just got an Amiga keyboard on ePay, but alas, no easy mice... (not even the Atari/Amiga switchable ones... :-( ) Anyone have a working spare they're willing to sell? "Have Paypal, Will Travel"... Also... Jay: If it'll help you track down the Reply-To: address munging "weirdness" Evan's email address *always* comes up with the list address's's's; I always have to manually remove his address from the To: field when replying to a post of his.

That ensuing discussion lacks any useful detail. For people who haven't read it, here's what it said: "IIRC, Killdall stood up in court and entered a keystrokes at a PC running MSDOS and brought up an easter egg he had programmed into CP/M years earlier, proving they had used his code." What we're trying to figure out is the keystrokes and the MSDOS version. Here's another account: http://dfarq.homeip.net/article.php?story=935 "Back in the mid-1990s, PC Magazine columnist John C. Dvorak wrote something curious about this operating system. He said he knew of an easter egg present in CP/M in the late 1970s that caused Kildall's name and a copyright notice to be printed. Very early versions (presumably before the 1.0 release) of DOS had this same easter egg." John A.

Free SS1000 for Boston-area pickup, needs new fan/sensor

by classiccmp＠crash.com

Free to a good home: Sun SPARCserver 1000 (not E) with one disk tray and one processor board. Includes two SM51 50MHz SuperSPARC CPUs I believe, 96MB of RAM (one bad DIMM in last bank), and 4 x 500MB SCA drives in "spud" brackets in the disk tray. PROM monitor reports a fan failure, though there are several working - might just be the sensor or cable, but Solaris 7 wouldn't load as long as this failure is being sensed. Chassis/case itself is in decent shape, some sticker residue, and it's heavy. I'll consider delivering it if you're 15 minutes away from Arlington, MA, but otherwise you'll need to pick this thing up or pay for the UPS Store to pack it - I'm not packing it for shipping. And of course you'd then have to pay shipping... First come, first serve... Thanks for the bandwidth, --Steve. smj (a) crash (d) com

Because they can be used to break car windows quickly, cleanly, and quietly. They are popular with car thieves. (much as dent pullers can be used to yank out the ignition switch). If you have just a center punch on you (or one with a bunch of other tools), you likely won't have an issue... on the other hand, if you are walking around the streets at night, have a center punch, dent puller, screw driver, and pliers... you best be on your way to hot wire your OWN car, of you will probably find yourself with a bunch of explaining to do. >Centre punch, cordless drill, >Citroen Special tool BFH-14 (Big, um, *Friendly* Hammer, 14lb), >boltcutters, hacksaws, sockets, spanners, screwdrivers, that kind of >stuff.

MS Network Client under DOS 3.3 working

by vcf＠siconic.com

For what it's worth: I got Microsoft Network Client working under DOS 3.3 on a 386/33. It works very well. I was able to connect to my WinXP system and copy over just under 500 files. I also got it to work reliably with a 3Com Etherlink III. Before, I whined that it kept crashing. Well, this time when I was setting up, I realized that the MSNC setup program advises that it will use more memory to optimize network performance but gives you the option to forgo optimization. I had it forgo optimization, and I think that made all the difference. At some point, if it becomes necessary, I'll also test on an 80286 and even an old XT system. Once again, if you want to download MSNC, I have it all bundled up in a zip file here: http://www.siconic.com/download/network/ (Note: I changed the location from where it was before.) This directory also contains the 3Com 3C5x9 configuration utility, but it's also included in the ZIP file, so no need to download it separately. -- Sellam Ismail Vintage Computer Festival ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintage.org [ Old computing resources for business || Buy/Sell/Trade Vintage Computers ] [ and academia at www.VintageTech.com || at http://marketplace.vintage.org ]

Web forums vs mailing list (was Re: minor list changes)

by dave04a＠dunfield.com

>Given the task at hand, given the needs of the users, given the >recently described hassles, is mailing-list technology the best >design and solution for this task? I prefer the mailing list for several reasons: 1- I am on dial-up. I can just "let it download", and then come back to read the messages as quickly as I like - web based clients are SLOW on dial-up, and you have to be there to click on every item you want to read, so you have to wait for it. This by itself would probably be a show stopper for me. 2- The list comes as nice plain text. If I want to save something, I simply save it - Saving text from the web is usually (not always, but usually) much more a pain in the butt. 3- Many sites nowadays use "extensions" and other goodies (and I use the term loosly) which make them unreadable on my anicent browser... It's fine to say "you just have to upgrade your browser", however there ARE no newer browsers for the particular platform that I use - If staying connected to this list means that I have to change to a "modern" OS, then I would simply wave goodbye and bow out. I expect there are a few others who would do the same... 4- Another point relating to #3 - this system I am using does not EVER download a "plug in" or applet and run it - attachments that I do accept NEVER automatically launch themselves (and if they did, they wouldn't know how to run here) ... so this machine has no "anti virus" software, doesn't need it, and never gets "infected" (because it never auto-runs anything). I have no doubt that a web based interface would have all kinds of neat-cool java applets, plug-ins and other things which compromise security - Even though the "list" site might be safe, forcing people to turn these things on will cause trouble for those of us who choose to avoid them. 5- The mailing list has an element of privacy - Since you have to both know about it and manually subscribe to it, there's a good chance that by the time someone shows up here they really are more than casually interested in classic computers. Once we get links from non-classic sites (hey, here's a place where I've seen XP installs discussed), and indexed by the search engines, you can bet that non-topic material will rise.

picking locks

by Saquinn624＠aol.com

I haven't had very good luck with paper clips. A better tool is a used dental pick, because this is tempered and holds up when you put stress on the lock with a tool (screwdrivers are not the best tools to use, as they can dent/flatten the lock noticeably, but in absence of a better tool they work.) Put the screwdriver in, apply pressure, stroke the lock pins with the pick. If you're really into it, you grind and temper a thin tool with a bump at the end. The computer locks I've seen (excl. IBM Medeco) don't need this, though.' -Scott Quinn

8-bit low profile ethernet card?

by nemesis-lists＠icequake.net

I'm looking for a 1/2 to 2/3 height 8-bit ISA Ethernet card. It's for an embedded type application. I can find "short" cards in terms of length, but not in terms of height. Anyone have any leads for me here? :) -- Ryan Underwood, <nemesis at icequake.net>

Big list of floppy disk formats?

by julesrichardsonuk＠yahoo.co.uk

Does such a thing exist? It'd be nice to have an online resource of all the different floppy disk formats used by different machines. Yes, that's one huge list, and would likely never be complete - but as I haven't come across an attempt at all so far, it'd be better than hunting around for the data when needed. I'd be happy to collate stuff if it's thought to be a good idea - I could make it available online too (although maybe one of the recognised repositories such as bitsavers would bea better place) Data can be fed into the futurekeep project as and when necessary, as it's something that'll be needed there too one day. thoughts?

Chorus Systemes?

by julesrichardsonuk＠yahoo.co.uk

Anyone know anything about Chorus Systemes and what they were up to circa 1990? I'm just unravelling a lot of old internal Acorn code/documentation and the name's cropping up quite a bit... (I do recall using a distributed system called Chorus in the early 90's, but I have no idea if that's at all related...) ta Jules

They cut a DEC key for me and it wasn't right so they re-made it. One of the better ironmongers near here can do various keys, including, I think, tubulars. They've cut bike D-lock keys, Mul-T-Lock security keys and various other odd ones for me. -- Pete Peter Turnbull Network Manager University of York

Well, I won't claim that this refutes the above, but I know that some Tek products have used W95/W98 for many years.

It is a little hard to describe from this sense. You could pick stuff with the select and then you execute it. It would be hard to create a software only emulator. The physical keyboard was as important as the software on this machine. Talking with Jeff, he said that several efforts have been made to get the keyboards on PC to work but there are just too many variations on how the keyboards are handled. It was left too much up to the builder of the machines. You really need low level access to key strokes and the layout is wrong as well. Dwight

minor list changes

by jwest＠classiccmp.org

I changed two things on the list setup tonight. 1) To subscribe to the list (new subscribers, not you guys), requires not only a confirmation email, but also list owner approval. I'm having way to much trouble with "people?" joining the list and all their email immediately bouncing. It gums up the speedy delivery for everyone else. 2) I changed the max time in queue for any message (outbound) to 35 minutes. This means the server will try to send email to you once, then again 30 minutes later, and then it will just give up on you. It won't unsubscribe you at that point, it takes like 7 days of bounces to get you unsubbed. But it won't try to send you any given list post more than twice now. Same reason as above. For those sendmail inclined.... I considered setting up a secondary queue for slow delivery where any emails that take longer than X time get moved to a low priority queue. Quite frankly, I don't want to deal with it. I'd just get more complaints about posts being out of order ;) Jay

The console on all PDP-11s is at the same place, 777560-777566 (add "17" in front for a 22-bit system, though). The first word is the receive control and status register (CSR), the next is the receive buffer register, then the transmit CSR, and lastly the transmit buffer register. So if you have a terminal connected, and with baud rate, parity, and word size to match the M7800 settings, simply DEPositing a value into 777566 should cause the corresponding ASCII character to appear on your terminal. If you type a character on the terminal, it should appear in the lowest 8 bits of 777562. > However, if I have a unibus problem, isn't the M7800 which is in an > SPC slot still going across the unibus? Yes. But trying it will tell you if the problem is in the CPU drivers or the memory buffers, for example. -- Pete Peter Turnbull Network Manager University of York

8' drive on PC troubleshooting

by dave04a＠dunfield.com

All the discussion on stacking two PC supplies and cutting grounds to try and keep them isolated seems like asking for trouble.... I've had good results using a PC-AT supply, and a little homebuilt linear (and nicely transformer isolated) 12v supply stacked on it's output to power an 8" drive. (The 12v supply is actually built on the outside of the cover of the AT supply).

FS: ThinkPad 700C (SF Bay Area, free to good home)

by patrick＠vintagecomputermarketplace.com

I have an IBM ThinkPad 700C that boots Windows 95 (it actually runs nicely, I dare say better than Win2K3 on my current 1Ghz desktop). The display hinge is broken, so its aesthetics are lacking a bit, but if you've got another 700C that isn't working, this is a good machine for parts. Comes with power adapter, original docs, and battery (unknown condition). I'll ship to you for cost (US only, sorry), or if you're local you can pick up. If there are no takers, I'll be tossing it. Hopefully it finds a good home. It's a nice little machine, just outside my collecting scope. http://www.vintagecomputermarketplace.com/view.cfm?ad=1610 Thanks! Patrick

FREE: Toaster video tapes (copies). WANTED: Commodore PET ROM.

by dave04a＠dunfield.com

>Also, I need ROM 016 for my "chicklet" PET 2001. IIRC the 016 ROM is F000-F7FF. You can get the images of all the PET ROMs from funet. Depending on the board you have and the available replacement devices, you may have to build a little daughter card to adapt the selects - I did this many years ago when a ROM died in one of my 2001's - copied the ROM from the other, and made a board to adapt a standard 2716 - still going strong!
