RT-11 has always been 6.3, RSX-11 is 9.3 IIRC, and UNIX doesn't have any fixed format - though early versions had a fairly small limit on name length (12 chars?).

Microsoft Re-Liscencing?

by photze＠batelco.com.bh

Hi. Just heard about this, so I dunno really what I'm talking about... Appearantly, this company is (was) selling liscences for DOS 3.3. I'm guessing that this is from a deal with MS. Has anyone ever seen this? Is it available with another product, such as early Windows releases? Ciao, Tim D. Hotze

Basic PDP-11ish questions

by healyzh＠ix.netcom.com

OK, to aviod confusion the first system in question is a SMS-1000, with a PDP-11/73 board, 2MW RAM, RL02 Controller (DL), TK50 Controller (MU), Dilog DQ606 Floppy Controller (DY). The SMS-1000 has an internal Floppy and HD, which it thinks are a RD51 (DU) and RX50 (DU). The boot ROMs support DU (DSA, the HD and Floppy), MU (TK50), and MS (TS). I'm able to boot off of RL02 by entering in the bootstrap from ODT. I've got RSX-11M and XXDP RL02 packs, and can boot from either. I've managed to make a bootable XXDP floppy diskette. I can boot the machine directly off of the XXDP floppy on power up. I can boot the XXDP floppy >from the XXDP RL02 pack, and then boot the XXDP RL02 pack from floppy. However, if I power up and boot from floppy, I can not boot the XXDP RL02 pack. Is this because the Boot ROMs don't support RL02's? Does anyone have any instructions for a Dilog DQ606 controller? I gather that it can be configured to act as several different floppy drives. The drives that came with it are labeled as being a RX-50 and a RX-33, yet RSX-11M sees both as RX-02's. I'd like to get these changed back to RX-50 and RX-33. What does the device name 'MS', device type 'TS' stand for? My guess is a 9-Track tape drive. I've also got a PDP-11/44 that I'm slowly working on restoring. It's in two racks, one has a pair of RL02's which have been cleaned up. The other has the CPU, 2 RX-02's, 2 TU-58's, and a battery backup. In looking at the CPU, it looks as if it has a LED for the battery backup. Does that battery need to be in the system? I would just as soon remove them and not have anything to do with them since they are old lead-acid batteries, and I'm not very fond of such things (spent 3 1/2 years of my time in the Navy working on UPS's). Is there any reason that I can't just plug the whole thing into a power source outside of the rack. I'm asking since for all I know the battery and powersuppy in the bottom of the rack are some kind of power conditioning circuit. Also does anyone have any recommendations on how to go about testing out the power supplies on the 11/44? I'd just as soon not blow anything up. I have powered up the RL02's, but that is all so far. I'm waiting to test the power supplies before I get the remaining boards that I need for the system. Thanks, Zane | Zane H.

Cross listing auction items

by higginbo＠netpath.net

I'm trying my darndest not to get too involved in this thread, even though I started it, but I need to set the record straight: The URLs I sent weren't from ebay, they were from Haggle Online. An online auction that is totally free to buyers and sellers, unlike ebay, that charges a fee to sellers. Not that it really matters, since online auctions seem to be the new "great satan" on this list. I would like to point out though that if you don't know the true value of an item, why not let the public decide? What's wrong with making a little bit of money off a hobby? I know this probably isn't over, but I'll try to stay out of it, regardless.

Early Mac Clones

by allisonp＠world.std.com

<One of the smallest multitasking systems I've seen was the I/O processor <on the PERQ 2's. It was a Z80 with 4K ROM and 16K RAM, but said ROM <contained essentially a cooperatively multitasking kernel. Some tasks <were in ROM, others were loaded into RAM. OK, so the user never realised <what was going on, but that doesn't alter the fact that it was there :-) The smallest I've seen run on 8080 and fits in some 100 or so bytes. It was published in Kilobaud April 1978 page 102 and yes it was real. To multitask on most anything all you need is an interrupt and save the context of the current task and start some new task... the order, where the tasks are and memory allocation can be somewhat tricky but, for small tasks its pretty trivial. I've done it in 8048 MCUs where the resources were 64byts of ram and 1k of rom and the tasks were keyscan, display, serial IO and code conversion. The timer provided the interrupt. Allison

Files as files

by pete＠dunnington.u-net.com

On Jun 10, 14:56, Max Eskin wrote: > How do UNIX files work? Is there a header of some sort? Not really. Certainly not consistently across all file types. Often command scripts have a comment at the top, and some versions of unix (eg, Irix) embed a "tag" number into executables so they can distinguish individual programs/versions quickly, but other than that, filetype determination is done by looking at various parts of a file and comparing what's found ("magic numbers") to a database (the "magic" file). So, for example, my system "knows" a certain file is a command script because the first 256 characters are all ASCII (which means it's probably a text file of some sort) and the file permissions are set such that it's executable (not merely readable). It also knows that a certain file is an ELF-format executable for a 32-bit little-endian MIPS processor with a version 1 architecture (ie it will run on *old* MIPS cpus as well as newer ones) because the bytes at offset 1 are "ELF", at offset 4 there's a binary "1" (which in this context means 32-bit not 64-bit), at offset 5 there's another "1" (little-endian), at offset 16 "2" means "executable", and at offset 18 "0" means "MIPS" (not Sparc, 80x86, 68000, etc). Some magic numbers are much simpler to decode, of course: a file that begins with "GIF89a" is a GIF file, surprise, surprise. And the more you dig, the more detail you can work out. -- Pete Peter Turnbull Dept. of Computer Science University of York

Looks like I made a real splash with my first post since resubscribing! In my defense, all I have to say is this: If don't really know the current street value for an item and I want to get rid of it, the best thing to do IS put it on auction and post to similar lists and newsgroups. I'm sorry if I offended anyone. During my hiatus, I was spending alot of time on usenet, a place where this is done all the time. Guess I got a little brainwashed.

Wang PC-002 ??

by rigdonj＠intellistar.net

After reading Doug's message, I checked at my favorite trift store and found a pile of manuals for a Wang PC. NOT Personal Computer but Professional computer! The manuals seem to be sort of generic to all Wang PCs. None of the manuals mentioned a model number of the computers themselves but they did list the model numbers of the various options and accessories. I also found three Wang computers. They were under a pile of stuff so I didn't get a good luck at them and I don't know if they were Wang PCs or a different model but they looked like the PCs. Two looked like 8 slot electronics units (that's what Wang calls them) and the other looked like a 5 slot unit.
