Blackhole and Black Hardware

I've dealt with him on a number of occasions and he's pretty knowledgable about the NeXT systems. As for the software, there are a number of CD's, including one called Nebula, that has quite a selection of software for the OS. I believe that Black Hole sells some of them as well. Jeff

SCSI or Voodoo? (also, NeXT hd travails)

by mtapley＠swri.edu

>From: jpero(a)sympatico.ca >> From: Geoff Reed <geoffr(a)zipcon.net> >>.... >> you'll need to use FWB or another 3rd party HD toolkit, apple's HD >> formatter won't work with that drive. >> >... >Begin searching for the HD SC 7.3.5 formatter patch info, it will >detail how to manually patch it with free editor also from apple too. >The mod is only a hex and easy to find to mod on. >... >Wizard The URL's I found on http://euronet.nl/users/ernstoud/patch.html were a little out of date - but starting with ftp.apple.com and using "English-NorthAmerican" instead of "US" I got there. There may be other pointers. Have not tried out the patched version yet. I love this list. I actually needed this info today - and here it is! Thanks, Wizard! NeXT problem - got an IBM DPES-31080 off of ebay (mea culpa, perhaps I deserve the consequences). I can hook it up and it is recognized by the NeXT SCSI bus [1] as a "COMPAQPCDPES31080", so it's not totally dead. Unfortunately the first thing I did to it was run sdform. Sdform completed normally, didn't complain. Then tried to run "disk" to change the label and put a boot block in. I can read the label and change what "disk" sees as the label, but when I do that, or anything else, I get a lot of messsages that say sd1: incomplete disk transfer: bytes moved = 0x2000, resid = 0x2000, retry 1 I tried format from the "disk" interactive list. No complaints. Back to write label, or init, or any of the other options - same error message. Gave the drive to the local support desk - they "formatted" it no problems on a WinNT machine. I have an email out to them to ask whether they actually initialized it after that or not. Interestingly, they report the DPES has a different label than what I put on it and what my copy of "disk" still reports for it. Next thing I'll do, barring any better suggestions, is pop it into a Power Mac 8500 in a lab here and play with it using patched HD SC 7.3.5 (see above). Suggestions solicited and welcome. The drive is at home today, will be back in the office with the tools tomorrow. - Mark [1] But not always. It's not recognized, whether its active termination is on or not, if it's the only drive on the SCSI chain. It is recognized in an external case with one other drive and with one internal drive, and it's recognized if it's on the internal bus with the other internal drive. Not if it's internal alone. Have not tried it external alone.

Interesting web page on VAXen

by vaxman＠qwest.net

I ran across this page whilst surfing... http://cm.bell-labs.com/cm/cs/who/dmr/vax1.html Basically, it's Dennis Ritchies notes from their first meeiting with DEC on the VAX 11/780... Classic quote: They talked some about software. It was rather depressing. Most of it will be emulated. (Presumably in a 2MB machine you will still have to tell the assembler how big a symbol table to use.) The system itself will be new, but unimaginative. They did not seem to understand, for example, why or even how the command interpreter should be a separate process and not in the system, and why commands themselves should be processes. They are also still stuck mostly in assembly language. There are companies that are learning about how to write software, but DEC is evidently not one of them. Guess what OS their talking about :) clint

Building a new COSMAC Elf

by bob＠jfcl.com

I have some RCA COSMAC 18xx family parts, two 1802 and one 1806 CPUs, an 1861 PIXIE video (!!), a 1854 UART, and a few assorted support chips. I've decided that the best use for them would be to build an updated Elf (I also built the original Elf 25 years ago and have always had a soft spot for the 1802). What software is out there that can run on the COSMAC? Does anybody have a copy of Tiny BASIC or figForth for the 1802? I have the original Popular Electronics Elf articles, but I'd like to have a look at the schematics for the Quest or Netronics Elf versions too. Does anybody have copies that they can share? BTW, I have schematics and ROM listings for the original RCA VIP (CDP18S711), RCA COSMAC Evaluation Kit (CDP18S020, including UT4) and the COSMAC Microboard (CDP18S604), if anybody needs those.

Can anyone help with a ICS Remote Monitor and Control Unit?

by rigdonj＠intellistar.net

Can anyone give me any information about the unit above? It's made by ICS Electronics Corporation and it's a model 2351. It looks like it's made to receive serial data commands to auctuate relays and sense digital inputs. One port on the back in marked "Local Term" and two other 50 connectors marked "Digital Inputs and Relay Outputs". It looks like it might be fun to play with if I can get it working. ICS won't help. They say that it's too old. (I'll remember that next time my company wants to order something from them!) Joe

Probably so, but that's not my problem because I don't use them. If it's your problem, maybe you ought to try to do something about it, like bothering the vendor or finding a different e-mail reader that actually does the sort of filtering you need done. And yes, I've got a strong opinion about this. Your computer and its software are tools; if they're not doing what you need done, maybe you need to figure out what you need done and go find tools that do those things, or go harangue the makers of your tools 'til they come up with new tools that do those things, or make new tools that do those things. -Frank McConnell

Unisys "Micro A"

by allain＠panix.com

Unisys "Micro A" Anybody know about such a system? I took in a stray cat system a few months ago, started parting it out, saw something interesting, then put it all back together again. Today I booted it up (fits on 15A, hurrah!) and determined the following: Base system: Intel mobo w/8MB (** 80386, sorry **) Adaptec SCSI OS/2 on SCSI disk internal SCSI tape (QIC) external SCSI tape (DAT) VGA card Add-Ons: Unisys "Micro A" CPU card (perhaps DC113) daughter memory card two multiplexed serial cards Another Adaptec SCSI card, apparently for the Uni half of the system. Another Internal SCSI drive two external drives Surprized it actually does stuff. The "Micro A" system is controlled by three OS/2 Apps: Admin, ODT 1, and SCS (System Control Subsystem) (nice name) (huh?). ODT 1 is a cryptic CLI system, SCS is a boot console for the HW Anybody got any beans to spill on this? is it just a big printer controller? I noticed the Micro A is apparently microcontrolled. What was it sold for? John A.

SCSI or Voodoo?

by CARL.P.HIRSCH＠sargentlundy.com

Well, since the Mac Quadra 700 is of 91 vintage, it looks like I can ask questions about it... I found this on teamexcess.com - ST15150N Seagate 3.5" 4.3GB 1.6" Half Height SCSI H-ST-15150N Narrow 50-pin Assuming the jumpers are set correctly, should this work internally in a Quadra 700? thanks, -carl hirsch

Obviously you have no expereince with S100. The Voltages supplied to the bus are UNREGUALTED with a minima of +8, +15 and -15.

The measurments you made are mostly meaningless. Is it safe? Likely is but that done not mean it will run.

Interesting find

by cmcmanis＠mcmanis.com

In packing up my stuff to move it from the office building to a temporary holding facility in my garage, I discovered I had the other half of the MDB Unibus to QBus bus "interpreter" which the docs claim will allow me to either use Unibus peripherals on a Q-bus machine or vice versa. Way cool. This means I can set up my 11/34a to use the RQ11D talking to a ESDI drive in a BA23 box as its hard drive (plus an RL01) but this gives me much more capacity. I hope it works! --Chuck

Amiga 1000 "disk change" stuck?

by engdahl＠cle.ab.com

I told David Betz I would send him a fast Lisp interpreter I wrote in Amiga assembler about 15 years ago. Now I have to get my Amiga working -- a worthwhile interruption to my PDP-11 restoration. This is an original rev 1.0 Amiga 1000 with one floppy drive, expanded chip RAM, 2 megs in a StarBoard on the side, and nothing else. It's the first computer I ever bought rather than built from scrap. It cost about $1000 in the days when an IBM AT with EGA, 1 meg RAM, and 30 meg hard drive cost several thousands, and 1.0 VAX-MIPs meant something. All the original pieces and manuals are still there and intact except for the monitor which died years ago. I'm using a small B&W NTSC monitor until I get a VGA adapter cable built. First, I tore it apart and cleaned out the dust. Pulling the cooling air in through the floppy drive was a brilliant concept. That way the cheap and replaceable floppy drive doubles as an air filter. There was very little dust elsewhere. After trying 5 Kickstart disks, I found one that would still read. I can boot the Lisp development disk, and, with plenty of patience and retries, it loads itself into the RAMdisk. So, in theory, the Lisp interpreter sources are recoverable (I also have it on 3 backup disks). The floppy drive, or something related, has a problem however. The computer cannot see when I remove a disk, therefore, it never refreshes the cache when I change disks. It never realizes that the disk has been changed. So I have the Lisp sources on one disk that will boot successfully, Kermit and CrossDOS on another good disk, but whichever one I boot, I cannot read the other. It will take a while to remember/relearn how to run an Amiga. The reed relay actuated by the floppy drive eject button is working, and there is continuity to a large chip on the drive. I'm guessing the computer is looking for "disk change" (pin 34 on the interface), which is probably triggered by the reed relay. I tried an IBM-PC floppy drive -- it boots from that drive, but still doesn't see the disk change. I tried a different ribbon cable. There is continuity from pin 34 on the mainboard floppy connector to a pin on what looks like it might be a PIO chip. There are two of these 40 pin DIPs in sockets next to the 68000. I exchanged the two chips -- that made no difference. I examined pin 34 with a voltmeter, with the ribbon cable disconnected but power applied to the drive. It doesn't wiggle when I insert and eject a floppy. But testing this with the cable disconnected might not be a valid test. It might be strobed by "drive select". With everything hooked up, I don't see a significant voltmeter wiggle on the PIO pin -- again, it might be "drive select" enabled, or polled with a very low duty cycle, so that test might not mean anything. Now that I think of it, I seem to recall that the pin was low. That sounds suspcious. I would expect if it was strobed, it would be a low-true open collector. I need to go back and look at that again. Questions: Is there some software way to force the computer to flush the disk cache and take a fresh look at a disk? Is an IBM-PC 1.44 meg floppy drive an adequate replacement for the original 800K internal drive, at least for reading? I downloaded a bunch of floppy related "hacks" from an archive (Aminet?), but I haven't had time to parse them all yet, plus I can't see the IFF formatted diagrams from a PC. Bear in mind that I have only one drive, so drive select logic might not be needed. What is the mechanism/algorithm used to detect drive change? What could have gone wrong? If I get desperate enough, I'll cut pin 34 on the ribbon cable and run it to a pushbutton dangling outside the case (assuming that pin 34 is the missing signal). -- Jonathan Engdahl Rockwell Automation Principal Research Engineer 24800 Tungsten Road Advanced Technology Euclid, OH 44117 USA Euclid Labs http://users.safeaccess.com/engdahl

Amiga 1000 "disk change" stuck?

IBM 6109 personal typer?

by KenzieM＠sympatico.ca

I saw a machine this evening that looked like a PS/2. It had 2 3.5# floppies on the front, but there were no ports on the back. The keyboard cable was coming out of an opening in the side and the monitor cable was attached internally. There appeared to be a lock on the side that may have given access to the inside. It seemed like the keyboard had been unplugged. Does anyone know anything about these machines? The keyboard was missing from the end of the cable, but it had one of the connectors found on the older original IBM keyboards.

Altair 8800 front panel lamps

by John.Honniball＠uwe.ac.uk

I've just been reading "Computer: A History of the Information Machine", by Martin Campbell-Kelly and WIlliam Aspray. It mentions the Altair 8800 (on page 240) and describes the front panel: When loaded, the program would run; but the only evidence of its execution was the change in the shifting pattern of the neon bulbs on the front. Neon bulbs? Did the Altair really have neon bulbs on the front panel?

Seeking NeXT slab disk bracket

by ethan_dicks＠yahoo.com

OK... so I have this NeXT slab (25 Mhz '040), I have some 30-pin SIMMs, and I have a 4Gb SCSI drive. I even have software. What I don't have is a bracket for the internal hard drive. Someone brought one to lunch today, and it appears to have a couple of feet that clip on to the edge of the case, and one screw hole on the other side. Is there a place I can get a proper drive bracket? I suppose I can make my own, but I'm not sure it will stay put on the non-screwed-in end.

booting from RQDX3

by engdahl＠cle.ab.com

How does a PDP-11 boot from an RQDX3 controller? I have several 11/23's based on the KDF11-AA CPU, which has no on-board boot ROM. The Andromeda UDC11 disk controller that most of these use contains the boot ROM. These machines are in a 4-slot dual-wide card cage which is full. There is the CPU, a memory card, the disk controller, and a serial card. A couple of these machines are missing the disk controller. RQDX3's seem to be readily available, and there is adequate documentation of the card on the web (jumpers, cable pinouts, etc). Will the KDF11-AA be able to boot from an RQDX3? If not, can anyone suggest an good alternative? -- Jonathan Engdahl Rockwell Automation Principal Research Engineer 24800 Tungsten Road Advanced Technology Euclid, OH 44117 USA Euclid Labs http://users.safeaccess.com/engdahl

I only got to spend a couple of months on PLATO. But a team at Northwestern University liked PLATO enough but was bummed about the cost of the special terminals that the developed a CDC subsystem called MultiTutor, which ran the Tutor IV language (and thus you could port PLATO programs to it), but worked not only with the PLATO terminals, but with any kind of terminal that offerred at least cursor control codes. MultiTutor's coolest feature was the first example of what we'd now call a chat room. Instead of a scrolling display with lines of user-typed text prefixed by a username, you got a display segmented into channels, each of which was occupied by a user. What that user typed appeared in that channel on the screen. It was thus limited in the number of users it could support, but it was easier (IMHO) to follow a multiperson conversation. When I came to UN*Xen finally, I tried NTalk and YTalk for a while, but IRC has just never worked for me... I always want to go back to that MultiTutor chat room... Regards, -dq

('Duuh' -JEA) There has to be *some* code *somewhere*, and different controllers need different boot code (if only because they have the registers at different addresses). There isn't any ROM on a KDF11-A or KDJ11-A, so you need there to be some bootstrap code on one of the other cards. Third-party controllers often have unique boot code on the card. Most DEC controllers rely on a boot ROM being on a special bootstrap board (like a BDV11, which also has a line time clock and bus terminators), a ROM board (like an MRV11-D) or a multifunction card (MXV11, which also has DRAM memory, clock, and serial lines for the console and one other serial device). Most of the DEC bootstraps for Qbus systems offer a choice of boot options (different disks, network, etc) and in addition will do a simple memory test (or at least write to it to ensure the parity or ECC is correct); many of the later ones are interactive. -- Pete Peter Turnbull Network Manager University of York

For those of you who would prefer to use a more modern compiler, and who can run a 32-bit version of Windows, there is a version of the Gnu Compiler Collection (GCC) that runs in a Win32 Console Session (not really a DOS box, but close enough), I recommend you search for this particular package: gcc-2.95.2-crtdll.exe Unpacked, it's 23MB, and all you need after unpacking it (it's self-extracting) is to set your PATH to the bin folder of the directory into which you install it. At any rate, hpasm.c compiled with no changes, as did chkabs.c. OTOH, I have not yet tried to assemble the sources for the MSU 4-user BASIC and compare the binary output to the existing binary he has on the site. So, the proof remains in the pudding...

Washington D.C. Trip

by jlewczyk＠speakeasy.net

Jason, I agree that those museums are a MUST SEE for any vintage computer enthusiast! You forgot to mention (did you miss it?) that they have the origional "Mark-8 Microcomputer" that Jon Titus built as found on the cover of Radio Electronics in 1974! It was right next to the micros and micro magazines exhibit. Jon was a guest at VCF in 1999. I reckon that the burn-in on the Xerox Alto was an early "desktop theme" or "screen saver" (did the Alto have that feature?). If I recall correctly it reminded me of cartoon-like butterflies, flowers, or a bee or something like that. There were a number of Altos placed into service at the White House for use by secretaries there, and perhaps one of those is what ended up at the nearby Smithsonian. I understand that the secretaries that got to use them, loved 'em. Its a pity that none of the computers on display at the the museum actually are working. I think that is a major flaw in their presentation. I found the videos running as part of the Enigma exhibit and the Eniac exhibits to be particularly interesting.

Call for Resources for CDC 6000/Cyber 70 Series Emulator

by dhquebbeman＠theestopinalgroup.com

Howdy! I'm gathering the resources necessary to build an emulator for the CDC 6000 Series, Cyber 70 Series, and Cyber 170 Series mainframes. I'll be pulling together existing works-in-progress and using Bob Supnik's SIMH as a framework. The fruits of this labor will be freely available to any and all, as with the DEC emulators. As to the CDC-owned software, efforts are underway which are hoped will lead to a hobbyist license, a la DEC's. I have a good start on the manuals I need (kept some from years ago, will acquire others). Additionally, I've sent two of my four old CDC 9-track tapes to be read and placed on CD-ROM as images. If any of you (whom I have not already been in contact with) have any printed source listings, coredumps, or best of all, 9- or 7-track tapes containing operating systems (the CDCs used a deadstart tape and a system library tape), would you be willing to have the tapes imaged-to-disk, and make the images available to this project? Thanks in advance, -doug quebbeman

Museum Computers (was Re: Washington D.C. Trip

by Robert_Feldman＠jdedwards.com

The Exploratorium devotes a fairly large amount of resources to exhibit maintenance, so they have more operational exhibits than most museums of their type. As to making stronger I/O devices, the first thing you need to do is observe a bunch of grade school/middle school kids when they come to a computer in a museum exhibit: they don't look at what they are supposed to do, they just start _pounding_ on the keyboard/input. What we did at the Field Museum of Natural History in Chicago (where I designed and programmed 10+ computer "interactives" for exhibits in the early 90's) was to use arcade-game trackballs and switches made by Happ Controls. At the time we started, these trackballs were not PC compatible. They did use standard slotted wheel sensors, though, so I just desoldered the sensors from the circuit board of an inexpensive Microsoft compatible mouse and ran wires to the sensors on the trackball instead. The mouse switches were also removed and wired to separate game-unit buttons. I made the first interface about 10 years ago, and I am still using it (at this very moment, in fact, hooked to an IBM laptop.) It's in a big foam-core box (10x9x4 inches), so it is not the sharpest looking thing, but it has never given me any trouble in 10 years of use. (Try that with a mouse!) Some museums use touch screens, but at that time, we could not find any that were reliable enough and precise enough. I later did a game fro the Brookfield Zoo that used a touch screen, but needed to use large on-screen "buttons" with good separation to get reliable picking. Using a trackball for input means that any character/numeric input must be done through on-screen selection, which is a bit klunky, but better than having a non-working exhibit. The one program that used (and still uses) keyboard input is the "Voyaging Game" located in the back of the Pacific exhibit (a dark and quiet area). It has benches in front of the screens for the users to sit at. Here, in a more tranquil setting, the visitors do not pound on the keyboards, so they have survived fairly well. (They even survived having holes drilled through them, when some exhibit installers mounted a label on the case surface above the keyboard, and drilled too far!) The biggest problem is someone will occassionally pop off a keycap, even though they are recessed in the case. -----Original Message----- From: Mike Cheponis [mailto:mac@Wireless.Com] Sent: Thursday, May 31, 2001 12:05 PM To: classiccmp(a)classiccmp.org Subject: Re: Museum Computers (was Re: Washington D.C. Trip Perhaps these so-called "museums" need to visit SF's Exploratorium? There, everything is meant to be "hands-on". This doesn't mean that things don't break from time to time, but the percentage of operational exhibits there is greater than any other public museum I've seen. Mind you, I'm not saying people should put an Eniac cabinet out where people can slobber over it, but I think it would be cool to be able to remote-control these older machines (I dunno, like a 360/50 or something) via modern interfaces - safely away from the original equipment, but yet behind glass - so you can see the original machine running.

Not in the sense of running boot code from an RQDX3 as it has no boot ROM. It's possible to use a KDF11-A or KDJ11-A with an MXV11-B -- those were common combinations -- with the MXV providing RAM, SLUs, and boot ROM in a single slot. An alternative is an MRV11-D which supports the same boot ROMs. Or you could use microPDP-11 boot ROMs in a modified BDV11, but that would take up two slots. -- Pete Peter Turnbull Network Manager University of York

The other is Dennis Bathory-Kitsz's LNW-80, which I bought from him. The other one I have is one I've never heard of before. I got the unit in a bunch of other TRS-80 equipment. The case is a hacked TRS-80 Model I keyboard, with a standard TRS-80 Model I keyboard with built-in keypad (very late Model I keyboard). The power, video, and cassette connectors are a match for the Model I. The CPU board has a built-in floppy disk controller, and is a Model III clone. The manufacturer appears to have been Norcom. -- Eric Dittman dittman(a)dittman.net

no HD Disks in 1541/71 and hub rings

Yes, the main reason for hub rings was to minimise the damage when you did that :-) Our Apple Disk ][s and Commodore 4040/8050 drives never needed disks with hub rings when they were new, and the ones I have now still don't. > Anyone have a hub-ring kit still?

Yep DD even reccomended for the 8050,8250 or SFD1001 (which are quad density drives), HDs 3.5" kinda work in 1581s but also aren't reccommended. Over the past few years I've cleaned out our local 'dollar'ish stores of 5.25" disk 10-packs when they get em. As for hub rings I heard they were required (for gripping purposes) for the older Apple drives (the metal boxy ones), maybe even for the 4040s, but I know without them on those old lever drives, you could sure mangle a non-protected center hole clamping down on one.

I've got a 9404-400 running v4r5. The system has a Qic tape drive and CD. I have a 8mm drive that I want to add to the system. The expansion chassis has room and open connectors. I hooked up the new drive, but I cannot seem to make the system 'see' it. What do I need to do to make the system see the drive so I can use it?? Any suggestions are appreciated, Thanks in advance Terry

Apple Turnover?(OT long, boring, maybe humor)

by mmcfadden＠cmh.edu

Little know facts about apple turnovers. 1. The hard part is convincing the apple to turn over when it's done on one side. A human analogy is how do you convince a sleeping sunbather to turn over when they are burnt on one side. 2. There have been government funded trials of robot arm based image analysis programs that will automate the process for only $10,000 per apple to be turned over. The only successful installation is in the International Space Station where gravity is not a factor so the apple will turn over due to convection currents in the air flow. That's where the term convection oven comes from. 3. There are also CIA funded research to examine whether there is a "apple turnover gap" due to Russian experiments with apples and psychic phenomena. 4. Apple turnover is a code word that Echelon uses to identify Russian defectors. apples are red and Russians are red, defectors are turncoats or turnovers. Russian defector=red apple turnover 5. Board game http://www.gamesdomain.com/GDLive/1201.html 6. Q: When does an apple turnover? A: Who Cares I'm digressing! Mike McFadden mmcfadden(a)cmh.edu

New HD disks not working in 1541?

by gunther＠aurora.regenstrief.org

Hi, now that I have my old C64 setup back I found that I could not format newer 5.25" HD disks on the 1541 or 1571. It just bumps and blinks and stops. Does the 1541 require hard sectored disk? I don't think so, because I can still remember today that my first disk ever said "BASF Flexi Disk, 5.25", Singled Side, Double Density, Soft Sector." So what's the trick to get media working? Bulk eraser? (BTW: It's been over 15 years and I still have that disk and could actually read one side of it, that's fun!) thanks -Gunther -- Gunther Schadow, M.D., Ph.D. gschadow(a)regenstrief.org Medical Information Scientist Regenstrief Institute for Health Care Adjunct Assistant Professor Indiana University School of Medicine tel:1(317)630-7960 http://aurora.regenstrief.org

New HD disks not working in 1541?

by pete＠dunnington.u-net.com

On May 30, 14:23, Roger Merchberger wrote: > HD disks AFAIK won't work at all in any DD drive - the TPI (Tracks Per > Inch) are different. DD disks are 48TPI, HD disks are 96TPI. I have to say that this is not true. Plenty of DD disks are rated for 96 or 100 tpi. Furthermore, at the microscopic level, there is no difference between a DD disk sold for 96 tpi and one sold as 48 tpi. There might be more gross defects in older sold-as-48 tpi disk than in 96 tpi ones, I admit, and that could produce an error when narrow tracks are written. Nevertheless, the magnetic coercivity of the disk is the same in both cases. The difference between HD and DD is NOTHING to do with tracks per inch, it's ENTIRELY to do with the coercivity (which is a measure of the field strength required to produce the magentic polarisation used to write the data). -- Pete Peter Turnbull Network Manager University of York

New HD disks not working in 1541?

On May 30, 11:02, Gene Buckle wrote: > I don't ever recall seeing a HD disk with a hub ring. The only ones that > have them in my experience is the SD or DD disks. Oh, I've seen quite a few HD disks with hub rings. But most of the disks I've seen with hub rings have been relatively recent DD/SD. However, the reason I menmtioned it was that the 1541 owner insisted that she needed DD disks *because they had hub rings*, not because they are the correct coercivity; in fact she said she'd used a few HD disks but the lack of hub rings on some of them caused them not to work. So told her she was using the right disks (DD) but for the wrong reason. -- Pete Peter Turnbull Network Manager University of York

FS: HP-150A

by bills＠adrenaline.com

I need to clear a little of my collection (that or hire a divorce lawyer) so I want to move a few things I have multiples of or just don't have the time/skill/interest to fool with. So, first on the list: HP-150A Fully functional, with keyboard, _NO_ HP-IB peripherals or cable. There were leaking batteries in it, but the corrosion has been cleaned up/neutralized, new batteries installed and it works fine. Will provide MS-DOS 3.20 boot disk (single sided works with 9121 disk) with PAM and utilities if desired. Best offer by 4PM June 1. Thanks!

Heathkit oscilloscope

by liste＠artware.qc.ca

I finally got my hands on an osiclloscope! 10 CAD at a garage sale this week-end. The beast is OLD, but works! I can't find a model number, but it says "Push pull" and "Extended range" on the front. I bought it with an course text book from Institut Teccart Montreal dated 1944 (in French). Last couple of chapters are about tubes, which is nice because my knowledge of tubes is limited. OK, so it's not a computer, but, uh, I'm going to use it to debug computers! Yeah, that's the ticket. But it doesn't go to very high frequencies... SO I'm going to use it to debug 9600 baud serial connections! Yeah, that's the ticket. -Philip

As others have said, you need disks intended for single-density or double density, not HD. I've also met one 1541 owner who swears that disks without hub rings won't work in his drive (and never did) because the mechanism doesn't grip them tightly enough (though I'm fairly sure that's just due to a soft spring or a missing screw on the frame somewhere). -- Pete Peter Turnbull Network Manager University of York
