Does anyone have any clues about where to get jumper settings for a Fujitsu M2263E ? Fujutsu's websites ignore the existence of ESDI drives. I've also tried The Ref and Blue Planet who seem to have got their data from Fujitsu's sites. This is a 600Mb drive and has what looks like write protect set for the partition area. Hans Olminkhof

6809 vs. '286 (long - Was: Re: Still OT: Pentium / M$

by allisonp＠world.std.com

<If that's true, I'd really like a PDP-11! ;-) I have a few they are fun. <> It was however, slow! < <Compared to what? Clock per clock, it was the fastest thing for quite a <long time. And remember, the 6809 was *not* the fastest of the fast Compared by instruction cycle time. <8-bitters... ever heard of a *6309*??? Pretty rare critter there! Made by <Hitachi as an OEM to Motorola, CMOS, 3MHz (most overclockable to 4MHz) and <would kick a '286 in the backside easier than anything 8-bit (with 6309 <hand-optimized code) -- it did have twice the registers of the 6809 and ha <-- no typo here -- 32 bit math capabilities. Well I am familiar and the 6309 was still not so fast. It was however programtically efficient. Well written programs used less code and therefore executed quickly. Also the extra registers and long math made it particulary nice for compiler target for C language. <>Comparing it to a 286/10mhz, sorry, no way. < <I did it. Admittedly, it wasn't *purely* apples to apples comparison, but <took totally portable M$Basic programs doing integer & real math, and <integer, real & string sorting, and ran them in RS-DOS on a CoCo2 and in <Basic & BasicA on a True-Blue Bummer/AT '286-10.

Your not comparing CPUs, you compared BASICs. Interger math is faster as iwould be five byte reals compared to the floating ppoint used on the PC/AT. A more reasonable would have been a collection of sorts and math tests that are in asm for the target machines. The 286 would have looked far better and the 287 would have made the case stronger. <vs. optimized assembly? IIRC, most (if not all) instructions execute in <fewer clock cycles on the 6809.

X86 instuction set is strange but it is efficient. The problem is programming philosophies and methods are very differnt between 68xx and x86 due to type and use of registers and addressing modes.

hard disk & controller from an AT.

by jim＠calico.litterbox.com

Hey all. I was just looking through my junk collection with the idea of organizing it a bit, and I happened across these chunks of a PC. 1 western digital WD1003-WA2 16 bit mfm hard/floppy controller. 1 seagate ST4053 5.25 inch fullheight hard disk. 45 meg mfm. >from when I looked it up. Both can be yours for the price of shipping. Note that the drive weighs about 10-15 pounds so do factor in shipping from Colorado. As to whether they work, in short, I have no idea. I'm told the PC they came out of was functional when I got it, but I used its case for a pentium box I put together for a friend and stripped and threw out the AT motherboard that was in it. -- Jim Strickland jim(a)DIESPAMMERSCUMcalico.litterbox.com ----------------------------------------------------------------------- Vote Meadocrat!

You wouldn't really _want_ that elevator to stop working when you're trying to make the appointment on the 40th floor, would you? Sure, it could fail for other reasons too, but this is something that ought to be double-checked since we know about it.

Apollo problems

by rexstout＠uswest.net

having trouble getting the old DN3500 to boot, with the original hard drive and the system in service mode I can get it to go a little ways, but when I try to launch the config and testing programs, it crashes. Nothing on the screen, but the C & D lights are flashing. Can't seem to find anything on the web that will tell me what that means. And when I plug in the 780MB drive, it works fine but the OS isn't installed so all I get is a no sysboot error. Although I'm told that one of the two 780MB drives has the Domain/OS install stuff on it, I'm just not sure how to get to it. -------------------------------------------------------------- | http://members.tripod.com/~jrollins/index.html - Computers | | http://www.geocities.com/Area51/Lair/1681/ - Star Trek | | orham(a)qth.net list admin KD7BCY | | ham-mac(a)qth.net Portland, OR | --------------------------------------------------------------

Need: Northstar Boot Disk

by bobatk＠EXCHANGE.MICROSOFT.com

Anthony: Regarding your year-old posting: http://www.heydon.org/kevan/mlists/classiccmp/1998-01/msg00022.html Did you ever find a disk? I've got several such disks, and could help you out, especially as it appears that you're a local (I'm in Woodinville). On the flip side, my MD5-AD3 seems to have gone south over the last decade of non-use, and I'm looking to replace it, or at least find one to temporarily swap with to confirm that it's indeed the disk controller that's iffy. Would you know of anyone that might be able to help me out? Thanks. Bob Atkinson 425-936-5570 (w)

Dynabook

by kurtkilgor＠bigfoot.com

I read a little bit about the concepts of the Dynabook, mouse, and other stuff in Steven Levy's macintosh book Insanely Great. However, I would like to know more. I have heard on this list that the research at PARC, and their products, are related to this and that Smalltalk was an attempt at the sort of operating system/programming language necessary for a true Dynabook. I also looked on the net and I didn't find a whole lot. But was the Alto the only such attempt ever made? I am discounting all of the cheap GUIs based on it like MacOS and GEM. Were there any _real_ ones? It seems the Apple Newton is somehow related, and I could see why, but I discount it from coming close because it is an extremely inflexible system, just like MacOS. Are there any ongoing projects? I would appreciate any insight ---------------------------------------------------------------------------- ----- Max Eskin | kurtkilgor(a)bigfoot.com | AOL: kurtkilgor

I have never heard of the Philips Micom word processor. That's not so strange, Philips has made a lot of different computer systems, it is an enormous task to catalogue them all. Sometimes Philips even sold the same computer under two different names, e.g. their third XT clone was known as the NMS9100 for the consumer market, but sold as the P3105 by a totally different section of Philips to the professional market, and it was the exact same machine. I tried several web searches for 'Philips Micom', but all I could come up with were a couple of firms offering conversion services for its files, and a CV of a Canadian researcher who mentiones having written software for the thing. I once saw a very old Philips wordprocessor, with a cabinet a the size of a cubic metre under the desk, a separate terminal for i/o and a weird thirteen bit parallel daisywheel printer which had no smarts at all (the computer had to tell it how many microsteps to turn the roll and move the head etc) but this machine used magnetic cards the size of a punched card to save files to, not disks. The P2000 family I was talking about has four lines that are incompatible with each other. - The P2000T (cassette, 40 char video) / P2000M (disk, 80 char video) which was the most common here in The Netherlands. They were the same internally but had different video. Most programs were interchangable. A CP/M card was available for it from the Philips computer club. Also a floppy disk controller for the T that was compatible with the internal one in the M. - The P2000C luggable, the most advanced one, CP/M, even had a 8088 'CoPower' card available for it that could run MSDOS. You could attach an external hard disk via a SASI interface. It could read and write the disk formats from all the other members, and of a lot of CP/M systems too. - The P2000B/P2500, a CP/M disk system with 5.25i disks, monitor and disks in one cabinet like the P2000M, on top of a passive backplane cabinet like the Northstar with everything on cards. 8i floppy controller available. - The P5020/P5040 word processor system. The P5020 was a monster system, an all-in-one system with a 15 inch 36 line system, two 5.25i drives next to the monitor, internal card cage with passive backplane (not the same as the P2500). The entire thing stood on a big tilt/swivel pedestal. Heavy keyboard made of metal, no plastic exept for the keys. The P5040 was a more modern version, smaller and looking like a PC with separate monitor and all. There was an add-on machine, called the P5010, which was a keyboard with a single line lcd display and a cassette drive, which could be used to enter long texts. You then transported these texts serially to the P5020 or P5040 for the finishing touches. Maybe this system was the Micom, I don't know. Some bright minds in the Philips computer club made a new ROM for the P5010 so you could write Z80 machine code programs with it. Later there even was CP/M for the P5020/5040. Multiplan with 36 lines really was a treat. I only have pictures of the P2000M and the P2000C on my pages. The other systems are buried in the garage, it would take quite some digging to photograph them. I'll go look if I have some magazine pictures of them.

The dark blue is actually a switched off cell. I know it sounds backwards, but when I disconnected the video cable once, and only the backlight was on, the whole thing was dark blue. I tried a little program that reverses the color, until something else changes it, and it's actually easier to read (as long as the contrast is set right). It's actually easier to read than some CRT's that I've seen, because the letters aren't fuzzed out at the edges. -- -Jason Willgruber (roblwill(a)usaor.net) ICQ#: 1730318 <http://members.tripod.com/general_1>

Old Microsoft MSX standard?

by rcini＠msn.com

Hello, all: While reading some late-1984 Byte mags, I came across a description of the Microsoft MSX computer standard. Implemented mostly by Japanese computer manufacturers, an MSX computer is CP/M based with 32k of RAM, a cassette port, RF modulator, and cartridge slots for expansion. I picture a Z80-based VIC-20 or C64, although not in that physical form. Anyone have any info on this?

DN3500 motherboard question

by rexstout＠uswest.net

(A copy of this message has also been posted to the following newsgroups: comp.sys.apollo) Got lots of Apollo stuff today, including two 4000's with no CPU chips, two 3010/3000 motherboards and a 3500 motherboard. But for now I have only things bothering me. First, what are the specs on the PC compatibility card and how do I use it? Second, which 3500 board is better, the 11858 or the 15652? What's different between the two? My current 3500 has the 15652 and I'm wondering if I should leave it there or switch the boards. ---------------------------------------------------------------- | http://members.tripod.com/~jrollins/index.html - Computers | | http://www.geocities.com/Area51/Lair/1681/ - Star Trek | | OrHam(a)qth.net list admin KD7BCY | ----------------------------------------------------------------

Old NCR printer

by dann＠greycat.com

Not sure if this is on-topic, but if not, just tell me; I'll go quietly :-) A friend gave me a working (!) NCR6416 laser printer (he was clearing out a shed), and I've got it hooked up to a Linux box on my net. It has some small problems I feel sure I can fix by giving it a thorough cleaning, but my main problem is docs. My friend lost the manuals for the thing long ago, and NCR doesn't seem to remember they made it. I need info on switch settings, front panel switches and indicators, programming, etc. About all I've been able to find is that it uses a toner cartridge type that is still readily available. I can print straight text to it fine from Linux and VMS, but I need to know more to print from OS/2, apparently. *sigh* Need a clue, people; any help *greatly* appreciated.

Fujitsu FW5020M05 and Macintosh System Disks

Can anyone provide information on a Fujitsu external floppy disk drive for the Mac? It is model number FW5020M05.

I have tons of working PC's, but not networkable Macs to use to do this. Or, if anyone can dup me a copy of System 6.0.4 or 7.0.1 I would appreciate it.

Philips P5020 / MICOM (was: Re: "Single instance" machines)

On Thu, 31 Dec 1998 19:37:24 +0000 (GMT), Tony Duell said: >> - The P5020/P5040 word processor system.

One of >the slots in my machine has a RAM card in it (64K I think). >I know nothing much about it, and I don't have any form of system disk >for it. Well, after I sent the message I began to doubt. Apart from the P5020 there was another computer that looked exactly like the P5020 but had a totally different machine inside. Floppys and screen were the same but the rest wasn't. It did not even have a Z80. I saw them at the computer club. They were called the 'Televerket' and were supposed to be some kind of communica- tions system for a Scandinavian PTT. I think it was also called P5900. The software for it was developed in Forth, so the Forth fans in the club were happy with them. I may have seen the card cage in this machine. You shouldn't have said you didn't have a system disk for your P5020 :) now you made me unearth my own P5020. Or at least try to. This is not an under- taking for the faint of heart. The machine is in my garage. In the back of my garage. The garage has two doors. The one in front that a car is supposed to go through (this has only happened once, in 1986 I believe) and a regular one in the middle for me. Imagine that you take a piece of chalk and attach this to the bottom of this door, at the far end, so when you open the door into the garage you draw a half-circle on the concrete floor. This circle then represents the border of how far you can walk into my garage. So I put on my coveralls, donned my old miners helmet with the strong lamp on the front and I started digging a corridor, by lifting stuff out of the way and putting it back down behind me. Soon the batteries of the lamp began to fade but just at this moment I found my P5040. There was a floppy in the right hand drive. Since this machine is compatible with the P5020 I dug it out quickly and went for the door again. Back onto safe ground I opened the P5040 and saw it had a large PCB on the bottom, and a daughtercard with two eurocard (DIN41612?) connectors for expansion cards, like your P5020, one of which had some kind of communications card in it. After being connected to the mains the machine booted at once. The disk was a CP/M 2.2 disk for the P5020. It had the spreadsheet program on it I mentioned earlier. I found my memory got warped after all those years because it turned out to be the Supercalc 2 program by Sorcim Corp. It claimed to be made for the MICOM 3003. So there you have it: Micom 3003 and P5020 are the same machine. I guess the Micom that Lawrence has is going to be the P2500. I made an image of the CP/M disk with Teledisk and wrote this image to a new disk. The P5040 also booted from this disk, but only if I put it in the right hand drive. This is a bit strange, since when you switch on the machine with no disk in it, the left hand drive lights its led and does a seek. Ah well. I can email you this Teledisk image. You need an AT PC with a 1.2MB floppy drive to write the image to a real disk, since the P5020 uses 80 track single sided drives. You can use a regular 360K disk to write the image on, if it is from a well known brand this will work. Now I'm off to dig out the digital camera so I can put a photo of this thing on my web page, it would be a same to bury it again without a photo after all this trouble :) Kees

Fixing RK05 servo chatter

by rcini＠msn.com

Hello, all: I decided to play with my 11/34a over the holiday, and discovered that one of my heretofore working RK05 drives has developed a chatter in the linear positioner. Here's what happens: the drive goes OnCyl with no problem, but on the first acccess, the OnCyl light blinks, and I get a device error returned to RT-11. I opened the case and watched the servo during this process and it seems to move in and out by one cylinder during this condition. So, I figured that there may be dirt on the positioner optics. I used compressed air to blow it off, which had no effect. Any clues?

Need Help around Buffalo, NY

If anyone on the list if from around Buffalo, NT and can help to ship a DEC PDP-11 (in a BA-23 box) with some peripherals to me, I would appreciate it. I have the lead on a nice setup, but I won't be able to travel that far anytime soon because my daughter is too little.

Misc. DEC parts available

by rcini＠msn.com

Hello, all: Well, I decided to start going through some of my DEC spares, and came across a small pile of stuff which is of no use to me. So, they're up for trade: Qty 2 of each of the following: - 200/MC concentrators - LA36 power boards - LA36 logic boards - {assumed to be} LA36 drive belts - LA36 print heads The working condition is unknown, as I have no way of testing these items. The 200/MCs power on fine and the LEDs on the back blink appropriately.

I just sent Zane Healy a bad SCSI TK50 adapter board. (my only spare). Based on Allison's post I would suggest checking the EPROM on yours and comparing to the one I sent him. I think he may be willing to part with it. I only sent it because I was sending a bunch of other stuff and had marked the unusual SCSI select on it for his ref. The fault on the one I sent him was nowhere near involving the EPROM. Dan

Shugart Model 801 (8 inch floppy)

by bill＠chipware.com

I have the above drive. It was shipped to me bolted in an enclosure. During shipping, it was badly shocked, shearing off the mounting bolts and damaging a couple of components on the electronics board. A couple of resistors and caps had their leads cut. Some creative soldering fixed that. One diode was smashed. It was on of those little clear (glass?) diodes. Are those called zeeners or something that starts with "z"? Anyway, I didn't have a replacement, so I just removed the leads and left it at that. Later I decided to go ahead and try the drive, and it worked. If somebody has the schematics, the silkscreen next to where the diode was is "C1" (it is in one corner of the board). Are there often nonessential components in older hardware? Is it actually nonessential or is some signal being compromised or some other component being overstressed? Bill Sudbrink

Still OT: Pentium / M$ drivel... (fairly long)

by allisonp＠world.std.com

>> The dynamics of the microprocessor market is more complex than you think <>> If MIPS was so good it would ahve pushed out x86. Alpha is a 64bit cpu <>> targetted at high end systems and the MicroVAX (32bit) was already well <>> established and faster than 386/486. < <I have to disagree with this, Allison, one of my points being: The value / <speed / whatever of a Microprocessor means little versus the *marketing* o <a processor / computer. to a point that is true. <The lowly Motorola 6809 at 2 Mhz outperforms a <10Mhz 80286... by far. It also *smokes* the 6502. And other than Xenix 286 <(super-expensive), OS-9 is the most powerful OS available for these <processors, and at a reasonable cost (When I bought my copy - $139.)... the 6809 was pretty neat and close to PDP-11. It was however, slow! Smoking a 6502 is not a contest, 16bit math and a few other things the 6502 has trouble with impair it. Comparing it to a 286/10mhz, sorry, no way. The 286 wasn't great but it was faster. Is OS-9 better than DOS yes, Xenix, no. Is OS-9 better developed than most intel/ms OSs, very likely. are there OSs for intel parts that show them better, yes. The 6809 was still a mile behind the PDP-11 (either the T-11 chip or the F11 cip pair and way behind the J11 chip). Like you said marketing... who outside of us remembers OS-9 and the 6809? Was the coco a better machine... no. It was good for it's time but the system was still a grafted together set of pods and cables typical of many of the trs-xx products. People noticed the PCs and the like when they started to look competent, complete and somewhat stable in operation. The contents of the box cpu wise was more determined by the software development community than the chip makers. IE: the guy in the lead for that time generally had the most and best software widely available at low or no cost. That's why AppleIIs, TRS-80s and PC are like house files for their respective times. No matter how good or bad software to make them do useful work often drove them forward. Allison
