Let's develop an open-source media archive standard

by melamy＠earthlink.net

to re-iterate, the separate sections I am proposing let the emulator do this very easily.

Drive alignment

by KParker＠workcover.com

Thanks Tony - I have swabbed it with Isopropyl alcohol - I assume that's the same thing. They're a real bugger as you have to pull the drives out to get to the heads because the things are so big. I figured an alignment disk was needed but was fishing a bit too as I suspect an 8" one is hard to find. Another theory I had was that I figured that Drive 0 has probably had a lot more use so I might try swapping them around if I can sort out the jumpers (if they have any) and see if I can get it to boot. +++++++++++++++++++ Kevin Parker Web Services Manager WorkCover Corporation p: 08 8233 2548 e: webmaster(a)workcover.com w: www.workcover.com +++++++++++++++++++ -----Original Message----- From: cctech-bounces(a)classiccmp.org [mailto:cctech-bounces@classiccmp.org]On Behalf Of Tony Duell Sent: Wednesday, 25 August 2004 9:08 AM To: cctalk(a)classiccmp.org Subject: Re: Drive alignment > > I have a TRS80 Model 12 that's been upgraded to a 16B (with two 8" > slim-line floppies).

How do I check alignment on the old classics. Take a known-good blank 8" disk and format it on one of your drives. If you can then read/write to it in that drive without problems, then the only thing that could be wrong with the drive is the alignment. If it fails, then you have other problems with the drive. To check the alignment properly, you need a CE (Catseye) disk and a 'scope. Basically the disk has a special patern recorded on it (this cannot be copied using a normal drive, BTW) and you look at the outputs of the read amplifier with a the 'scope. You see a pattern of 2 lobes on the 'scope screen -- if they're the same height the head is alighed, if one is larger than the other it's offset from the correct position. It's not hard to do, but the Catseye disk is expensive (I am still looking for the 8" and 3" ones, BTW...). My experience suggests that head radial alignment is not normally a problem unless you've replaced parts of the drive. More likely is a dirty head (you have cleaned it, right? With a cotton bud dipped in propan-2-ol, not one of those useless cleaning disks), a worn-out head, other mechnaicl problems, or an electronic failure. -tony ************************************************************************ This e-mail is intended for the use of the addressee only.

dos electronics software?

by jwest＠classiccmp.org

I've been searching the net for DOS based electronics software, and I'm coming up pretty dry. Was hoping someone had suggestions with all the electronics folks here. 1) Looking for a dos based databook application, primarily for 74xx series and such. Something that will give me quick access to pinouts, data sheet info, etc. I did find a promising dos app called ICID, but alas, when it goes to display pinout info it just blanks the screen on my Toshiba 3200 (only on the pinout page, the rest of the app displays fine). 2) Also need a DOS based semiconductor cross reference guide. I've found a few out there that are free, but they are all windows based. 3) Lastly, looking for a program that will collect data from and control my 1631 logic analyser via HPIB. I can't find anything on this. 4) Any other handy dos programs for the bench. Please help, I can't stand the thought of a Windows machine being on the bench next to me vintage gear :> Regards, Jay West --- [This E-mail scanned for viruses by Declude Virus]

dos electronics software? (PLDs)

by swtpc6800＠comcast.net

I was on the original team that developed ABEL, the Data I/O PLD language. I co-authored a book "Digital Design using ABEL" in 1994 that came with a special copy of ABEL version 5.0. I have this book in electronic form. I also have versions of ABEL from 1.0 to 5.0 that run without a dongal. These are DOS versions. I have a mag tape of ABEL 1.0 for VMS (I think.) Xilinx owns the current ABEL software and Prentice Hall owns the copyright on the book. However I will post a copy of my book and a full version of ABEL 5.0 on the web somewhere. I will make the link available on request. ------------------------------- Michael Holley swtpc6800(a)comcast.net www.swtpc.com -------------------------------

Resurrecting an early 80s SGI

by mail＠g-lenerz.de

Hello, I've recently added an IRIS 3130 machine to my collection. It is a MultiBus based SGI with a Motorola 68020 CPU, additional Floating Point unit and the typical 5 or 6 board graphics subsystem. It's complete with original UNIX documentation and owners guide as well as the original extras (monitor, keyboard, mouse). I'd like to get it up and running again but I can't get any of the backups back on a "fresh" ESDI drive (the original died). According to the Old IRIS FAQ the drive is supported. As far as I can see it is also detected but the process that should restore the installation back to harddisk dies quite early in the copy stage. Thus the current status is: The machine passes POST without problems, it can be talked into booting the installer and partitioning tool from tape but it crashes during the copy operation. As I said I'd like to get this beast up and running (i.e. have an OS Installed). A "nice to have bonus" would be having a working TCP/IP stack on it so that it can run in my network (an Ethernet board is present). Any hints / help is *very* much appreciated. I can -of course- provide additional information if it is needed. -- Best regards, Gerhard mailto:mail@g-lenerz.de Old SGI Stuff http://sgistuff.g-lenerz.de/

Semi-OT: Data Recovery?

by dickset＠amanda.spole.gov

So here I am... doing backups of an 80GB Maxtor drive when it craps out in the _middle_ of the backup. :-( >From my digging around this morning, there appears to be a problem reading the reserved area that results in it being detected by the BIOS as a "Maxtor ROMULUS" (the class of drive). >From further digging, it appears that I won't be able to shake this thing loose without professional help. I got 25GB of data off of it before it died, but since I don't have a directory, I can't even evaluate if it's worth $$$ to get the rest. So... before I proceed, I was curious who on the list has used professional data recovery services, and who does a good job at a good price. I've already written to a company in N.Z. that has a base rate of under $300 NZ + recovery media (DVD-R, CD-R, blank drive...) I've seen companies ask 400 Eur. and up to $700 US. Obviously, I'm not in a hurry now... it's still about 2 months to the first plane.

trade my Amiga 1080 for your Amiga 1080

by adamg＠pobox.com

I have a Commodore 1080 monitor (Amiga branded, non-stereo version) and the original cardboard box. The box and monitor have matching serial number stickers. I've saved the box for a while for completeness's sake, but now I want to get rid of it. Maybe someone has a loose 1080 they want to trade for a "1080 with original packaging"? The monitor was working the last time I tried it, and I will test it again if anyone is interested. The front panel hinge is intact. The box is a little scuffed/torn but not ripped to shreds. There is a noticeable tear along one side. I do not have any documentation, cables, styrofoam, bags, etc. In trade I will accept a working Commodore/Amiga 1080/1084/1902/S/whatever. I am in the Los Angeles area and am willing to deliver/pick up within a reasonable radius. I'm willing to ship, but I'll be slow and you'll have to pay shipping. OK, so it's a long shot, but is anyone interested? -- Adam

PDP 11/03 vs. PDP 11/03-L

by squidster＠techie.com

Hello list, Anybody can give an authoritative answer as to the difference between a 11/03 and a 11/03-L? What I can gather is that the 11/03 used a BA11-M/H9270 (4-slots) while the 11/03-L used a BA11-N/H9273 (9-slots). Another important thing is that the DEC logo is different! :-) On the 11/03 the font used is the regular lower-case font, while on the 11/03-L the font used looks like uppercase Avant Garde.. /wai-sun -- ___________________________________________________________ Sign-up for Ads Free at Mail.com http://promo.mail.com/adsfreejump.htm

Cleaning Yellowed Plastic...

by alhartman＠yahoo.com

I used to work for a company that repaired and refurbished monitors. What we used to do was use SoftScrub with bleach on the yellowed plastics, and once cleaned as best we could... Hit the pieces with Armor-All. That combination did a good job of making the plastic whiter, and restored a shine to it. I also think Armor all has chemicals in it that help protect the plastic from the Sun. Give that a try... (I also use spray cleaner with bleach to get into the crevices.) __________________________________ Do you Yahoo!? Take Yahoo! Mail with you!

Cleaning Yellow Grubby stuff

by rhahm＠nycap.rr.com

Here's what I do: 1.. For stuff in fairly good shape I use Simple Green and a Black and Decker "Scum Buster" rotary brush that uses the B&D rechargeabe batteries. I use the soft brush attachment. I usually remove the case and take it out in the driveway with a hose. If it is really yellowed I use Purple Power this will remove some , but not all of the yellowing, but it can stain metal so be careful. Simple Green is safe and works great for dirt and grime. 2.. For magic marker and stickers I use Goo be Gone and elbow grease. 3.. To finish things off I use automobile protectant Looks alot better after that.

I /think/ it was for a Wyse AT computer to allow the use of a standard PC AT Keyboard, but don't quote me on that. There is a part number on the moulding of the DIN - 940398-02 REV. A - but googling shows nothing. If anybody wants it, it's theirs for free; just cover the postage. Talking of Wyse ... I have two Wyse 120 terminals, a Wyse 30+, and another serial terminal I can't remember the brand of - (not a major one, and has reseller's name on the front) - all free to anybody who wants to come collect from Salford, UK.

cctech Digest, Vol 12, Issue 33, Re: Drive Alignment

by Watzman＠neo.rr.com

RE: Drive Alignment 8" drives are usually pretty stable once aligned, but perhaps not over a period of decades. There are two ways to check/set alignment. The "classical" (mid-70's) way is to use an analog alignment diskette and a dual-channel oscilloscope. You connect the scope to two channels of the read head amplifier and seek to the alignment track of the disk (my recollection is track 38 decimal, the center of the 77-track diskette). You should see a kind of "filled in dual sine wave". If it's symmetrical or close, the alignment is correct. If one lobe (every other one) is of significantly greater amplitude than the lobes in between, you are out of alignment and you adjust the position of the head to get it right (this part varies from drive to drive). Then you have to check some other things, like the track 0 sensor and track 0 phase (on some drives). You need the analogy alignment disk, a scope and an "exerciser", or a computer with software that could let you manually seek and load the head as desired. The "modern" (about 1981) way was with a digital alignment diskette. This was a normal data disk, almost, but various tracks on the diskette were either correctly aligned, or intentionally mis-aligned by varying known amounts. By seeing which tracks could be read, and which could not, you could determine the alignment status of the drive. This was useful for checking alignment, but not nearly as good for setting it. SOME of these disks ALSO had the analog patter on track 38. You needed the digital alignment disk and software that knew what to do with it. The problem today is that the alignment disks (of either type) are not readily available, and most PC hobbyists don't have a scope. Documentation, knowledge and experience are also issues.

copy of SCSI 1 spec? (XT39.2)

by julesrichardsonuk＠yahoo.co.uk

Hiya, has anyone got a early copy of the SCSI spec which just covers SCSI 1 (i.e. 8bit bus, 5Mb/s transfers only)? I want to see if I can get the parallel port on a modern PC hooked up to one of the old SCSI/ST506 bridge boards that I have, but given that I only have 12 data out lines to play with and 5 data in (13 in if I assume a bidirectional port) things are pretty tight and I obviously need to do some loading of stuff into external registers. I've got some reasonable info on the SCSI protocol, but having a better idea of which signals do what (and at what time) would be useful. All the docs out on the web seem to be for the latest SCSI revision though (and therefore contain a lot of info that I don't need). Furthermore I only really need the low-level protocol now; software-driven higher level command structure can wait for a few days! cheers Jules

HP2100a VS HP2100s

by MGemeny＠pgcps.org

Here?s a question for you guys. One of my HP2000 friends asked me what the difference was between a 2100a and a 2100s. Now, I have done a fair amount of maintenance on both and I can?t recall that I ever paid any attention to any difference between the two. Does anyone know of any differences between the two other than the name on the front plate? Thanks, Mike Gemeny

Anybody have an extra power supply for a PDP-11/04??

by bob＠jfcl.com

I was given a PDP-11/04 recently, in the short 5 1/4" chassis, but it is missing its power supply. Looks like it was removed to use as a replacement for another 11/04. Does anybody have one they don't need? Anybody even know what kind of power supply goes in a 11/04 in the short chassis?? Thanks, Bob Armstrong

RSX11M Boot disk

by Pres＠macro-inc.com

Need some help making a disk bootable under RSX11M V4.6 (not Plus). Need to copy a bootable system volume to another. Usually I use standalone BRU with no problem. Problem (I think) is that I have 2 MSCP controllers, one drive on one controller, other drive on the other controller and their low level formats aren't compatible so can't swap drives around. Unfortunately I have no working tape drive at the moment either. (I do have 5 TK50's with tapes hanging out their mouths though). Dragged out a Cipher 550 cartridge tape drive, plugged in MSV05 controller (MS:), bought some new DC600A tapes after the ones I had in the attic for 10 years didn't work, but it didn't work either. Disk and controller configuration is: An Emulex QD01 controller CSR=172150 Vec=154 (Standard MSCP address) with an RD54 as DU1: This is the system disk and it hardware boots fine into M. And a RQDX3 CSR=172154 Vec=150 (Secondary) with an RD32 that shows up as DU4: under M. I can BAD it, INI it, MOU it etc. -- drive works fine. Using standalone BRU to copy DU1: to DU4: it gives error -65 (device offline - it can't see it) for DU4: Ok, I use CNF to change DU4: to alternate CSR, it give me error -65 on DU1: Apparantly CNF changes DU CSR for both drives. (I did find I could make standalone BRU bootable RX33's though which I did as they boot much faster than TK50.) So, standalone BRU not working as I wanted, I made the RD32 DU4: drive a Files11 volume (BAD, INI etc.) Created all the UFD's from DU1: (system disk) on DU4: (target). (Still haven't found anything better than TECO for making command files >from directory listings, have a PC version of TECO I use today) I then copied all the files to the target disk: BRU/NOI/MOU DU1: DU4: Worked fine. I can mount DU4: and look at all the files fine. But, how do I make DU4: bootable as DU0: on an RQDX3 at standard address of 172150?? VMR and SAV only seem to work on the current SYSTEM disk, not a target. For example, tried to VMR DU4:[1,54]RSX11M.SYS --- no joy. When I try to boot the DU4: on another system, it give me what INI wrote in the boot block: "THIS VOLUME DOES NOT CONTAIN A HARDWARE BOOTABLE SYSTEM" Any suggestions on how to make DU4: bootable? Best I could find Googling was: http://www.miim.com/faq/hardware/diskfaq.html#mscrscpy But I don't see how that effects a drive other than SY: Any help would be appreciated. Thanks, Ed Kelleher

Puget Sound area collectors, heads-up!

by kyrrin＠bluefeathertech.com

Spotted yesterday at RE-PC Tukwila: A nice DEC MicroPDP-11/23 in a four-foot rack, along with two tape drives of a type I've never seen before (definitely DEC'ish, they look like they take a smallish cartridge). Also had what looked like a third-party 16-port serial MUX installed, probably an Emulex or similar board. No price on the thing, but probably available for cheap. RE-PC is at 510 Andover Park West, at the opposite end of the complex from the UPS customer counter.

HP 9133XV disc drive question

by rhahm＠nycap.rr.com

I recently aquired an HP 9133XV combination 3.5" floppy and 15M HD with an HPIB interface and Amigo protocol. I tried to use the drive with an HP 86B and an HP 85B computer. The floppy works fine but the computer will not recognize the hard drive. The HD seems to spin up normally. I tried an "INITIALIZE" command without success. Can the series 80 computers use this large drive? Does anyone know how to use the test function on the drive? Thanks

cool terminal manuals

by jwest＠classiccmp.org

Don't think I posted this stuff to the list before, if I have, my apologies. But when you have CRS syndrome.... For some of the ones listed below, I have like 30 copies (all originals) of the manuals. For others I only have one original copy. Some of these are off-the-beaten-path manuals and quite cool. Micro-Term Mime I & II Micro-Term 420 Micro-Term 5A Micro-Term Ergo 2000 Micro-Term ACT IV Micro-Term Mime 340 Micro-Term 2A (which does Soroc IQ120 emulation - cool, and I have the terminal :) Mini Bee IV Some of the manuals above are operating guides, some are programming guides, some are service/technical manuals. I actually have a Micro-Term ACT 5, very cute terminal.... and a 2A. I would VERY much like to find a Mime I, and maybe a Mime II. Anyways - thought I'd list the manuals in case someone is desperately looking for any of them. Regards, Jay West

Need Altos Diagnostic disk

by richardlynch3＠comcast.net

Help! I've been trying to recreate an 8" floppy from the Altos Diagnostic disk .tdo file recently added to the Commercial CP/M Software Archive site (http://www.retroarchive.org/cpm/) so I can try to diagnose a hard drive problem on my ACS8000-10A, and have so far been unsuccessful. I've been using a Shugart 800 8" drive connected to a PC/AT floppy controller with a 34-to-50 pin adapter, and have been wearing myself out with Teledisk, Anadisk and 22Disk for the last few days with no luck. I think I've got the adapter pinned correctly since I'm able to use certain functions OK, but not make that disk. When I try to use Teledisk, it tells me the .tdo source was a 3.5" high-density FM formatted disk (?), and when it tries to write out to the new disk, it comes up unable to find any of the sectors. Has anyone out there been able to do this, or know of another source for the Altos Diagnostic disk that has the hard drive utility? Thanks, Richard Lynch

ASR-33's and Brain Dead "Repair" man...

by dvcorbin＠optonline.net

Ok, I am at it again... Powering up the "really nice" ASR-33 that I pickjed up last weekend. After checking thing out [voltages mechanical inspection, etc] I have powered it up. [F4 the fuse for the motor WAS blown, a replacement of the ssame rating is holding]. Motor spins up nicely (real quiet and sweet!), with the mode set to local, the break and here-is keys do the "right things", however NONE of the other keys do. My first thought was an issue with the keyboard unit, but a swap >from my other (dirty, smashed case, etc) unit yields the same results. My next thought was the distributor [since checking the schematic shows that the break key does NOT require the distributor connectivty].... Powered down, disassembled to look at the brushes, they look brand new [cant wait till I get to post some pictures of this baby!!!!]. Every thing also seems to buzz out as I would expect. This indicates that the failure mode might well (once again) be me...... Hopefully someone here will think of something I am missing..... A reply e-mail would be appreciated, a call bfrom anyone with an idea and a few minutes would be great! [If it is long distance, I can call anyone willing to help]. My weekend will be some mich better if I get this working and buttoned up tonight [It's so cleen that it is even scheduled to go in the living space rather than my lab when buttoned up and working!

>From: "Vintage Computer Festival" <vcf(a)siconic.com> > >They have a *very* well done restoration page. Cool project! However, I >don't believe their claim to have the only original Alto left in existence >is accurate. Hi I was just wondering. What people on this list consider their rarest computers in their collections. Here is my list 1. Nicolet 80 ( 20 bit mini with core. working condition. Only know of 2 others. I doubt there are more than 10 left anywhere. ) 2. SIM-4 4004 development system ( most likely fewer than 30 left. Running. I only know of 2 others. ) 3. Olivetti M-20 ( Few in the US but maybe a couple hundred in Europe. Z8000 processor. Runs ) 4. Jupiter Ace ( Several hundred most likely exist but unusual in that it had Forth in ROM. Runs ) 5. NC4000 Delta Board ( Most likely only 100 around but most have no idea as to the collectable nature. These might be found in embedded system. These are unique in that they have the Forth processor on them that was designed by NOVIX and Chuck Moore. A 4 Mhz processor could run rings around a 33MHz 80386 of its time. Things like sorting 1000 integers in 19.2ms ) Dwight

would anyone read a couple of DECtapes for me? (USA)

by gtoal＠gtoal.com

Some time back our project (the Edinburgh Computer History project) organised a trip to Grenoble to meet Hans Pufal and read a box of DECtapes on his PDP9. Since then we've had a few more tapes turn up and I have a couple of them over here in the states. Is there anyone over here who would be willing to read them for us please? We have code to decode the contents; we just need a raw dump of the blocks. I have one which I can mail any time as a test (some old Fortran code, not very historically significant) and if all goes well I will be getting a second one soon from one of our group members which does have some significant code on it that we'd very much like to recover. Drop me a line - gtoal(a)gtoal.com - if you can help. (If you reply here, I'm not being rude by not replying immediately - I read this group in digest format so I get it a day late) Thanks Graham

Need help in finding old aritcle

by jrkeys＠concentric.net

For a grant I'm trying to get for the museum I need help in locating Knight-Ridder newspapers in the US and around the world that carried an article back in March 2000 about my collecting computers. The article was titled "collecting the classics" and was in the St. Paul (MN) Pioneer Press back on Monday March 13, 2000. Some of you remarked that your local paper carried the story also. If anyone remembers seeing it please email me the name of your local paper so that I can contact them. I need 3 US papers and 1 international paper. Thanks

Heathkit ID-5001 weatherstation

by dickset＠amanda.spole.gov

Does anyone on the list have any docs on the Heathkit ID-5001 weatherstation? I'm especially interested in schematics for the PSU board (I have no backlight, and one of the transistors gets _really_ hot), and the RS-232 command set. I've been googling for a while, and I've found a couple of interesting sites (like the one that sells aftermarket temp sensors to substitute for the LM3911 that the station comes with), but no abundant source of info. Thanks for any tips, -ethan -- Ethan Dicks, A-130-S Current South Pole Weather at 22-Aug-2004 00:30 Z South Pole Station PSC 468 Box 400 Temp -88.2 F (-66.8 C) Windchill -129.5 F (-89.8 C) APO AP 96598 Wind 11.1 kts Grid 052 Barometer 675.8 mb (10784. ft) Ethan.Dicks(a)amanda.spole.gov http://penguincentral.com/penguincentral.html

PDP 11/84 PSU wiring / differences

by julesrichardsonuk＠yahoo.co.uk

We were trying to find out why the left half of our PDP 11/84's backplane is dead earlier. Seems like it's not getting any power at all supplied to it. The system's got two power supplies in it - an H7202-KA which runs the right (working) side of the backplane, and an H7202-KB which runs the left side (and seems to be dead) Now, the left hand power supply is fed AC from a cable that plugs into a large mains filter on the left side of the cabinet, halfway up and midway between front and back of the chassis. AC is getting as far as the PSU, but there's nothing on the +5V output. There seem to be no fuses in the PSU itself, and no obvious sign of problem. Initial questions: 1) It seems that AC input is always available to the PSU with the power switches on though, so the PSU must be started via a signal over the ribbon cable that plugs into the PSU? 2) As well as AC input to the left hand PSU, there's also a pair of wires (yellow and green) which terminate in a plug up by the mains filter. There's nothing which obviously plugs into this - any ideas what it does? 3) What's the difference between the two supply types? The rightmost one is identical to the left, but with the addition of a second vertical board inside, and also runs the blower fan at the front of the machine. Is it just that it provides voltages other than +5V to the system? It's possible that we can source another supply in the near future, but I'm not yet convinced that the supply is actually dead - has anyone got a list of what the various lines connected to the supply actually do? cheers, Jules

IBM 5100

by ken＠seefried.com

From: Christian Corti <cc(a)corti-net.de> > >You can't change the microcode of the PALM processor. That would be like >changing the microcode of e.g. a MC68000. > Actually....you can do that. The IBM {PC,XT,AT}/370 card(s) (ISA-bus card that put a "baby" IBM S/370 on your desktop) had a CPU that was a re-microcoded 68000 (emulating some subset of the IBM S/370 mainframe instruction set). IBM licensed the architecture from Motorola. Probably got familiar with it building the IBM 9000 Instruments System. That, of course, doesn't mean you could do it on a PALM. Ken

>Thanks, but I don't have the required long torx screwdriver and case >cracker >tool, and I am a little scared to crack open the case, mean evil nasty >high voltages live >in there. Besides I might bust something inside and that would be bad. Screw driver, as others have mentioned can be bought at Sears. Case cracker you can also get at Sears. Buy a smallish spring wood clamp, then remove the rubber protective tips. The blade tips will then fit into the case crack, squeeze the clamp, and it pops the case open. Or you can do the Shake and Bounce method of loosening the case... but I don't recommend that. If you have to do a forceful method, do the light tapping around the edges method (or just pick up the dang clamp when buying your screwdriver!) As for the voltages, there isn't anything readily accidentally touched inside. The Analog Board (the one with the lethal power), is mounted in such a way that you can't accidentally touch the inside of it. You have to try to reach in and do it. And the back side of the board (that you can accidentally touch) is covered with an insulating sheet, so you can touch away and nothing will happen. HOWEVER, removal of the logic board, so you can upgrade the RAM, can lead you to needing to reach into the lethal zone. The board was designed to slide about 1/2 inch and then release from one side of the cage, letting you tip the board out and then disconnect the power, floppy, hard drive (if there is one) and sound. However, I've yet to run into an SE that the cables are really long enough to let you do that with any ease. It has always been MUCH easier to reach under the CRT, and disconnect all but the sound while the logic board is still in place in the cage. THEN remove it from the cage and disconnect the sound. So there is a little bit of "danger", but it isn't anything to really worry too much about. I'd be happy to supply you with a PDF of the take apart manual along with the SIMMs if you wanted. -chris <http://www.mythtech.net>

HP 9133XV disc drive question

The floppy > works fine but the computer will not recognize the hard drive. The HD seems > to spin up normally. Do you have the option 010 for your 9133XV. The HP product catalog implies that only opt 010 works with the Series 80. In general Series 80 computers cannot really deal with a hard drive. They only know about floppies, and since they have only one-level directories, there is little to be gained from large capacity hard drives. So HP cheated. Since (at that time) hard drives were small (5 to 10 Mb), they provided special firmware on the hard drive to create 4 hard partitions, each the size of the largest floppy drive recognized by the Series 80. So the HP 9133A 4.6 Mb hard drive is split into 4 1.2Mb volumes. However for late Series 80 models, HP did something else as well. An intriguing note in the HP catalog says: > The HP 9133B and the HP9134B are single volume 9.6M byte Winchesters > which can operate with the HP-85B or the HP-86B; they can also operate > with an HP-86A or HP-87 when used with an 00087-15012 Electronic Disc > ROM and ROM drawer. 9.6M byte Winchesters are supported under native > mode. What the ^%@#$@ does this mean? Does the Electronic Disc ROM contain code to soft partition a 9.6Mb volume? I do have an Electronic Disc ROM for my 87XM, but I have neither the documentation nor a suitable Winchester. Any clues are welcome. **vp

Hi It is more likely that his service includes other countries that restrict encription machines. I don't think the US restricts looking at encription machines.

Hi This is not a WW2 machine. This was made many years after that. It is an Enigma design with more wheels than the ones the Germans used. It is a ridiculous price for a later machine, regardless of condition. It is most likely military surplus but not WW2.

That and the fact that the machine seems to run really >well on OS 6 >and I have found many fun things on the net that also run on OS6. I fully understand your reluctance. I can say that if you decide to try it, and you break something, it should be fairly trivial to track down another SE for free (I for one have a half dozen I don't need, and I'm sure Sellam has a half dozen pallets of them!) But I still understand. >I'll try installing the OS7 I'll be getting soon - but perhaps it won't >work, so >back to OS 6. no problem. OS 7 will probably not even boot with only 2 MB of ram. I think the MINIMUM you will get it to boot with is 2.5 (which you may actually have, it was very common to go to 2.5 instead of 2, because you just left two of the 256k simms in place when adding two 1 MB ones). However, even at 2.5 MB, System 7 will be almost unusable. 4 MB really is the minimum you can get away with. But honestly, if you can find fun things to do with System 6 (and there are tons), then stick with it. It will run MUCH faster, and be MUCH more stable on an SE then System 7 will be no matter how much RAM you can cram in there. -chris <http://www.mythtech.net>

The 1.44 drive will read and write Apple ProDos 3.5" floppies. As for plugging in an Apple II drive into the floppy port on the Mac, don't do it unless you are sure the drive is one compatible with the mac. Most of the A2 drives were not, even though they had the same connector. They could damage the Mac. There were however some that were compatible with the Mac. I know there was a 3.5" drive that worked with the Mac or the A2, and I think there may have also been a 5.25" drive that worked with both (not counting the one for the A2e card that plugged into the card's adaptor cable). -chris <http://www.mythtech.net>

>Apple still has system 6 and 7 on their website if >you need it but getting system software from the net onto 400k floppies is >not easy if you don't have an old Mac already. Apple has 6.0.8 and 7.5.3 and the 7.5.5 updater available as free downloads. They do not have previous versions of System 6 or 7, nor later versions of any OS revision. That's actually OK, as performance wise, there is little difference on an SE between System 7.5.5 and System 7.0 or 7.1. And .5.5 is more stable and has better networking support, so there is really no reason to run a previous version of System 7. Same can be said for System 6.0.8 and previous versions. There is really no reason NOT to run .8 so there should be no worries about lacking earlier versions. And although your comment about getting them onto floppies still holds true, it is worth correcting that the SE uses 800K drives at the minimum. Some of the SEs uses 1.44 drives. The best way to know is to look at the front of the case. If it says either SuperDrive or FDHD, it is using 1.44 drives. If it just says SE, it is probably an 800k drive (also the back label will likely tell you). Hopefully this persons is a 1.44 drive, so they at least have a half a shot at creating the disks on another computer. If they are in fact 800k drives, that could prove a challenge almost as much as 400k. Later Macs can't read/write 800k disks as well as the 400k, and PCs I don't think can do 400 or 800 at all. (I think there are ways to get PCs to write the 1.44 disks however, and at least those are readily doable by any newer Mac with a floppy drive). -chris <http://www.mythtech.net>

Article on data rot on CD's

The other day I came across a table from a report showing the relative longevity of data on various media (DLT, CD-R, etc) at a variety of temperatures and humidities. I'll try and find it again and post some of the results. Some of you might be shocked. For example, a CD-R with an expected lifetime of something like 25 years (if I'm not misremembering the highest figure) under ideal conditions has a lifetime of only several *months* at higher temperatures (upper 20s C, that would be 80s F) and humidity. DLTs fared much much better. I have some CDs that were bought about 8 years ago because they were supposedly good quality, and burned in a highly-rated burner. Out of the first batch of ten, 4 are now unreadable or give multiple errors. -- Pete Peter Turnbull Network Manager University of York
