Mini-Monitors?

by allisonp＠world.std.com

<><Does anyone know of a *cheap* source of a VGA-compatible display? What <><looking for, especially, is low power usage, followed by compactness an <><portability. Thanks! At 5$ it's interesting to have as a spare assuming the shipping isn't over 20$. <>I'm also interested in same and know someone that might like info. <>There is a truck load of applications for a cheap/compact/lowpower <>VGA display. I should elaborate. I'm looking for a mono (or color) display that is very low power and size is not that important other than I need to be able to see 80charx24line text on it. Graphics are not required. While some CRTs can be under 10watts power my desire is an order of magnitude lower if possible. An LCD would be ideal but alas none are available (low cost) that have more than the basic LCD drivers. The DELL laptop LCD I have is typical of the MONO 640x480 displays and the "video" input is not like a crt in timing or signals. For example the display is really two 640x240 running in parallel with seperate video for each. Hand built logic to do that costs enough in power and design time to make it unappealing or no better than a good mono crt unless I resort to Gals/FPGAs (design effort and cost prohibitive for a one up).

CP/M

by maxeskin＠hotmail.com

I have started bringing home the expanded Apple II+. It has an external "Executive Peripheral Systems, Inc." keyboard, with program macro modules for Wordstar and Visicalc (great keyboard,if only it clicked), and the regular DuoDisk. I also brought home the DR CP/M card manual. The Apple II and floppies will be brought home next week. I was firstly thinking of putting this into a PC case, since the keyboard is external anyway. But I was reading the CP/M manual (pretty shallow), and it mentions a 16-user capability and password protection. How does this work and how secure is it? Also, would you say that the Z-80 was better than the 8088? It was certainly used much more... ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com

Someone had e-mailed me the pinouts for the AST PenExec (aka GRiD Convertable), but I lost them when my e-mail crashed. Whoever it was, could you be so kind as to resend them? Thanks! Also, the GRiD version was available with a 386 (2260) and 486 (2270). Does anyone know if there were also two AST versions?

Also, would you say that the Z-80 was better than the 8088? It was certainly used much more... > The "16 user" isn't really a multi-user capability. Unlike MS-DOS, Unix, VMS, etc., CP/M did not have subdirectories. The main directory was it, everything fit there. This was not so convenient, so "user areas" came into being with CP/M v2. The 16 users are actually numbered subdirectories. The "C> USER 5" command would switch you to subdirectory 5, equivalent to a "C> CD \DIR5" in DOS. The idea was if multiple people used the machine, each would have their own area. On V3 the user 0 area was a common directory, I think there were some commands to control this (very rusty on CP/M V3). I don't think CP/M V3 was ever implemented on the Apple card, since V3 was designed to use banked memory over 64K. As for 8088 vs. Z80, I would rate the 8088 as one step above the Z80. It was slower, but had a larger instruction set and a crude MMU built in, out to the 1MB limit so familiar today. The Z80 was a bit faster at the same clock rate, and the 8088 never got to a very high speed, IIRC it got to about 8 or 10Mhz in the Intel version, NEC sold variants out to 12Mhz. The Z80H was an 8Mhz part, it kept up with the 4.77Mhz original IBM quite well, except for the memory limitation. BTW, on S-100 systems the 8086 was far more common than the 8088, since the S-100 could support a real 16-bit bus. Zilog and Hitachi eventually extended the Z80 out to 512K and then 1MB with an MMU too, but it was never as flexible as the segment registers in the 8088. As far as design difficulty, using an 8088 or Z80 was about equal. The 8088 had a minimal mode for small designs, or support chipset for expanded systems. The Z80 took some random logic for the clock signal and needed some type of MMU if you needed more than 64K. Jack Peacock

Early Mac Clones

How does this soft-microcode thing work? Doesn't it imply that there is some kind of "sub-microcode" needed to load and process the soft one?

Heathkit replacement manuals

by dcoward＠pressstart.com

I just received the H-11a manuals that I ordered last week from the Heathkit's manual replacement service and I just wanted to let any one who is looking for old Heathkit manual know how I made out. I'm very happy with the manuals I received! First I ordered just the Assembly and the Operations manuals. One was $35 (I think) and the other was $45. After I hung up I realized that I had not asked about any schematics or illustration booket that usually comes with these manuals. (By the way, I asked about any EC-1 manuals and she said I was the fifth person to ask about those in the last week, no they don't any manuals for the EC-1) I received the Assembly manual and the Illustration Booket xeroxed DOUBLE sided on 11"x17" paper (also folded but not stapled). The Assembly manual did not have the traditional brown jacket, but I could take one off an old color TV assembly manual. I also received one schematic of the chassis power supply, front panel, and backplane on what seen to be about 20"x25" paper. (It does not look like it's been reduced in size). The Operation manual is about 3/4" thick and most likely came originally in a loose leaf binder. It is xeroxed again double sided and on 8 1/2" x 11" paper. (You can see were the 3 holes were punched) In their letter with the manuals they state that the manuals are nonreturnable but they will "attempt to correct any problem with the quality of the copy". I found they friendly, helpful, and fast. Their number is 616-925-5899 The only problem I've seen so far is with thw xray views of the circuit boards, the RED circuit traces on the foil side of the board do not xerox at all. ========================================= Doug Coward dcoward(a)pressstart.com Senior Software Engineer Press Start Inc.

What distinguished some drom is that ther stored words using multiple parallel heads making them very fast. On PDP-10 I used in 70/71 had a 128kw swapping drum used to hold the swap file. It's my understanding (and memory) it rotated at 1200 or 1800 rpm and stored 18 bit parallel words. I've also used a PDP-8 that had RS/RF08 disk that was structured like a drum with 12bit parallel access (32kw per platter). It was also quite fast. In all aspects durms and disks are the same thing. <> why they wouldn't be, offhand. But I thought drums died out before <> Unix appeared. Does anyone still have a functional magnetic drum <> memory?

Unix filenames and drum memory (was: Files as files)

by peacock＠simconv.com

True? Were filesystems on drums managed the same as those on disks? I don't see any reasonwhy they wouldn't be, offhand. But I thought drums died out before Unix appeared. I last used a drum on a Univac 1106 (FASTRAND II), the file system was the same as a disk drive. A drum is just a 2 dimensional disk, track and sector but no head select. Univac had fixed head drums and moving head drums, don't recall the capacity (it wasn't all that big). The drums on the 1106 were retired in 1971 when it was upgraded to a dual processor 1108 with a room full of short stack disk drives (20MB packs). Good thing too, the reliability on the drum wasn't so great, heads would often get out of alignment, you would suddenly have half of your file and half of someone else's. BTW, as a bit of trivia, a friend of mine who worked for the CIA in Vietnam had the job of actually grinding off all the oxide on retired disks and drums, so there would be no possibility of recovering data >from them. Might be one reason they are so scarce now. Jack Peacock

Mini-Monitors?

by sinasohn＠ricochet.net

Does anyone know of a *cheap* source of a VGA-compatible display? What I'm looking for, especially, is low power usage, followed by compactness and portability.

Pre-Color Computer Terminal??

by a＠aol.com

Greets! I was wondering if anyone might have any information on an old machine produced by Tandy/Radio Shack. It came out _prior_ to the Color Computer, but it looked like a CoCo. However, it was a modified with a phone jack in the back for a TV/monitor and ran off of a 6809E (???). It basically was a videotext terminal of some sort. If anyone might have some information on this little unit, your help in learning more about it, and it's purposes, and maybe some history on it, would be much appreciated. Oh, yeh... an off-topic question? Is this text formatted correctly. I had some problems with my mail software and had it completely messed up trying to fix the original problem. Anyway, let me know if the text is going off the right of your screen or whatever, and if my signature box at the bottom of the page is formatted ok, ok? If it is, great! If something's wrong, feel free to send a private e-mail back to me to let me know ok? Thanks, CORD COSLOR -- ____________________________________________________________ | Cord G.

online support (was: old laptop BIOS???)

At 08:27 AM 6/10/98 +0000, you wrote: >> I've found Toshiba's on-line support for their older machines to be >> excellent; I wouldn't be surprised at all to find that the setup pgm was >> available on their web site.

Yes, Toshiba could yank the files from their site, but unless they went out of business (not likely) why would they? Doesn't cost them anything (coupla meg of hd space) to keep them there. Probably more expensive (people time) to get rid of them. An incredibly valuable marketing tool for very little (or no) cost. Because of what I found there, I would definitely consider a Toshiba laptop. >else. IBM, Gateway what you have that have long term service I wouldn't touch a Gateway computer to save my life. I've got a Gateway 2000 Colorbook that my sister uses. I sent them an e-mail to simply ask what models hard drive they used (I got some empty sleds, and my hard drives didn't fit) and if they still sell sleds/hard drives for it. Was told they didn't know, didn't care, not interested. Suggested a couple of places that sell used GW2K stuff. I have a long-standing loathing of IBM, though I must admit some of their more recent laptops look pretty nice. (Can't stand the damn erasers, though.) They do seem to be pretty good about offering support and info on older machines. Basically, if a company isn't interested in helping out with their older (sometimes much older) machines, I'm not interested in their new machines, simply because whatever I buy today I'll still be using when it qualifies for this list. --------------------------------------------------------------------- O- Uncle Roger "There is pleasure pure in being mad roger(a)sinasohn.com that none but madmen know."

> But the VAX-philopsophy was extreme CISC, and that extended to the VAX/VMS filesystem as well: record-based, with a zillion different file attributes, built-in file versioning, etc. It was hierarchial, but mixed with a clunky "volume" concept (something like DOS "C:", but with longer names). I wouldn't call it "clunky". In fact with VMS you can combine drives into a volume set if you want the filesystem spread across multiple drives, or you can treat each drive as an isolated filesystem. As a system admin, I prefer the separate volumes, makes it easier to manage overnight backups. In our VMScluster individual disks are backed up in parallel across several tape drives (as many as four tapes in operation at the same time, depending on day of week), a trivial task in VMS but a bit more elaborate on a Unix system. As for the RMS file attributes and versioning, they are a dream for programmers, compared to PC or Unix systems. We have NT or W95 workstations at every desk, but we still keep a VMScluster running, partly for financial apps, and partly for coding. When you start dealing with larger apps (i.e 3K-5K users per week, 300-500 at any one time in a 24 hour day, all accessing the same files) you start to appreciate what VMS can do. BTW, one nice advantage of filesystem per disk is drive shadowing in VMS. You can mirror two drives during the day, then break the set, remount the mirrored drive as a separate disk, back it up, then reconnect it back to the shadow set. Instant snapshot backup without shutting down applications, all the database files are intact as of the moment you broke the shadow set, no updates during the backup. Jack Peacock

Bit slices?

<On Thu, 11 Jun 1998, R. Stricklin (kjaeros) wrote: < <> I suppose a better way of asking that is how is a 'bit sliced' processo <> or ALU differentiated from a 'normal' one? The concept was to take a vertical slice of the core of most cpus and make it so they can be cascaded to the needed width. Some of the common parts were the 3101 (intel 2 bit slice) and the 6701/2901 4 bit slices. Their advantages were speed, they were bipolar and in the 70 to early 80s you could make a z80 equivelent using them that was 10mhz and piplined.

IBM service rig?

by nerdware＠laidbak.com

Hi guys. I just picked up an IBM type 9075 laptop. The label on the inside (where the keyboard is) says it's an Aptek Personal Service Communicator II. It's got a 9.5" monochrome screen, a built-in thermal printer, what appears to be a modem jack, a screw-on (not BNC) rf-type jack, a socket for a pcmcia-type RAM card, and what appears to be a breakout box connector on the back. No floppy. Is this a field service terminal? If not, just what the heck is it? Thanks.

OK, I never got this "object" stuff, it's kinda confusing because it tends to make much ado about nothing (in poor implementations, yes, but I've only seen poor ones, the Newton being very hard to understand in terms of how to use). As for VMS file attribs does anyone know how many there actually were? I counted the attribs Norton DiskEdit lets me change on the Mac (bundle, locked, bozo, init, etc.), and there are at least 30. >> DOS in terms of having an array of blocks and stuff.

Yes, but so does a trackball or trackpad centered below the keyboard (which is one of the main reasons I bought my current laptop.) Best of all, IMO is the tootsie-roll from the Outbound. Mostly, however, I stick to keyboard commands (my one complaint about the MacOS -- you can't pull down menus and such from the keyboard). I strongly feel that anything you want to do should be doable from the keyboard -- if you're willing to remember how. (Example: in MS Word, there is a keyboard command to set bold/underline/etc. If I used Word a lot, and used bold/underline/etc a lot, I would remember it. Instead, for the few times I do that, I don't mind using the mouse. On the other hand, I can do just about anything in Eudora without using a mouse-thingie.) I do use a trackball -- a Logitech Trackman Marble. It's comfortable, accurate, and simply works great. The advantage of a trackball/other over a mouse is that on a mouse, when you click, you are also moving (however slight) the moving part. With a trackball, you can take your thumb completely off the ball before clicking. And I'll shut up now lest I get flames for mumbling off-topic too much. --------------------------------------------------------------------- O- Uncle Roger "There is pleasure pure in being mad roger(a)sinasohn.com that none but madmen know."

Some reporter asked him about multitasking, and Gates replied that multitasking really wasn't possible in anything under 8 megs of ram. To which the same reporter replied, "But doesn't your own Amiga Basic multitask nicely on a 512k Amiga?" A question which Gates promptly ignored and moved on.........

In general, file systems seem to fit into several simple categories. Let's say UNIX-like, DOS-like, simple (just data), and that's about it I've looked at Apple manuals, and the Apple ][ format is kinda like DOS in terms of having an array of blocks and stuff. Except Apple's is quite a bit more elegant.

Mac Portable Power Supply

by maxeskin＠hotmail.com

IF you mean the AC adaptor, you can use later ones (powerbook). This is actually beneficial because later ones are strong enough to power the machine alone, while the Mac Portable one needed the battery to be inside and working. I powered my mac portable for a few months w/two adaptors. The I put the battery in. Happily, it recharged fully from that high current (it was dead otherwise; I got the portable because it wouldn't start up because of the battery. I got it to run by hooking the battery up to mains AC long enough to "recharge" it). >I was wondering if anyone had a Mac Portable power supply, and wanted to >sell it cheap. > Thanks :), > Mike Sheflin > >______________________________________________________ >Get Your Private, Free Email at http://www.hotmail.com > ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com

Bit slices?

by mcquiggi＠sfu.ca

Bit slice processors are designed so that they can be ganged together with suitable interconnection, making an 8 bit ALU out of 2 - 4 bit units, etc. Generally good for accumulators etc with more complex instruction decoding outboard. My 2 cents... Kevin At 02:39 PM 11/06/98 -0400, you wrote: > >Hej allesammen; > >What's a 'bit slice'?

But there's a difference between a Z-80 running a text-mode interface, and an 8088 running a GUI. Also, remember that Bill Gates didn't know very much about operating systems, as opposed to languages. MS Windows is the only OS MS programmed ground up, something they only started after the A1000.

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

This is NOT a flame, but i'm just wondering the point of posting items that have been put up for sale on ebay, et al. all that means is every item will already be overbid on for an insane price. it is my opinion that if anything is announced as being for sale, the subscribers to this group should get first crack. david In a message dated 98-06-10 13:21:21 EDT, you write: << Some items on auction: Apple Portable, currently at $53.00 http://www.haggle.com/cgi/getitem.cgi?id=201635376 TI-99/4A, complete with about 15 games http://www.haggle.com/cgi/getitem.cgi?id=201639758 Also, looking for cheap Type I PCMCIA/JEIDA RAM cards. 1mb-4mb range. >>

Well, apparently we need to demolish the existing one-story building where the current museum is located, and it's always been a bit cramped for big school tours, so a new larger location was pretty much de rigeur.

As Doug mentioned, GRiD had one, as did the Mac Portable (1989) and the Atari STacy (year?). Not sure what year the Outbound came out but I'm pretty sure it was pre-thinkpad (maybe '89ish?). --------------------------------------------------------------------- O- Uncle Roger "There is pleasure pure in being mad roger(a)sinasohn.com that none but madmen know."

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. If it's gonna cause a problem, I won't let it happen again.

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.
