QuantumLink

by brain＠jbrain.com

I'm not sure how far afield Classic Computers goes, but I am interested in anyone here who used, worked on, or knew about the QuantumLink service for the Commodore 64/128 machines. With help from someone who's spent lots of time deciphering the QLink protocol, I am busy re-implementing the server. So far, the stock QLink disk will login and show the main page, you can select any of the 7 "message" areas and the screen will show menus for each area, and I am now working on implementing the "People Connection" chat system. By no means I have made even a dent in all of the functionality of the system (games, file downloads, etc.), but it is impressive to see the old disks and serviuce running again. Currently, I have the basic chat (join, leave, say) working for multiple users. Sadly, I never used the original system, so I am lost as to how exactly things progressed from screen to screen (where did you change you screen name, for example), so I'm eager to hear from others.

hardware bebugging...history repeating itself so to speak!!!

by cmurray＠eagle.ca

This incident reminds me of the debugging situation I had to do in Botswana some 23 yrs. ago. I had rigged up an air-conditioner that was controlled by a microcontroller, a novelty at that time. The temperature got so hot and the humidity so low that the microprocessor, an 8080, just wouldn't run right. I solved the problem by circulating water over the enclosed unit. Liquid-cooling so to speak! Computing forever; forever computing. Murray :) Message: 8 Date: Mon, 25 Jul 2005 03:18:55 -0500 From: "Director" <csmuseum at cse.uta.edu> Subject: RE: hardware debugging - history repeats itself To: "'General Discussion: On-Topic Posts Only'" <cctech at classiccmp.org> Message-ID: <200507250828.j6P8S0Uh010823 at keith.ezwind.net> Content-Type: text/plain; charset="US-ASCII" Last time the air conditioner at out farm went out it turned out that fire ants had built a mound inside the control box on the compressor outside the house. ;) Gil

AT&T 3B2's available

by jwest＠classiccmp.org

I saw a stash of 3 or so AT&T 3B2 systems. Don't know the exact model, but they are a common one I've seen before. They are a metal white case that normally sits on a desktop. Approximate dimensions are 17" wide, 24" deep, and 17" tall. The scrap dealer said I could have 'em for $35 each. They are not in mint cosmetic shape, one case appears a bit mangled. I have no clue what (if any) cards or drives are inside them. If anyone wants these as-is-site-unseen, let me know asap. Jay

DR DOS 5.0

by john_boffemmyer_iv＠boff-net.dhs.org

Actually, it WAS called DR DOS as it used to be owned by Caldera until 2003 (which was at one time part of Novell). It is now owned by SCO and, like most things SCO gets involved with, they take ownership, drive it into the ground and then abandon it like the group of a--holes they are. Last official DR DOS release was 7.03 by Caldera. SCO just wanted some of the pieces of it so they can make more of the "we have rights" B.S. claims that they make. SCO did absolutely nothing with it once it was purchased from Caldera. There are "unofficial" releases of DR DOS 7.04 and 7.05. They are part of Partition Magic, Western Digital, Quantum/Maxtor and Seagate/OnTrack Diagnostics. 7.03 would be the last and easiest to obtain. Versions .04 and .05 have pseudo-DOS FAT32 support, but it breaks certain basic DOS functionality and was actually customized from the .03 version for obvious specific purposes (drives larger than 80/120GB, etc). -John Boffemmyer IV At 09:55 PM 7/27/2005, you wrote: >I think its now called Caldera DOS - try Googling it > > > >++++++++++ >Kevin Parker >Web Services Consultant >WorkCover Corporation > >p: 08 8233 2548 >m: 0418 806 166 >e: kparker at workcover.com >w: www.workcover.com > >++++++++++ > >-----Original Message----- >From: cctech-bounces at classiccmp.org >[mailto:cctech-bounces at classiccmp.org] On Behalf Of Diego Rodriguez >Sent: Monday, 25 July 2005 4:26 AM >To: cctalk at classiccmp.org >Subject: DR DOS 5.0 > >Anybody knows something about its history ?? >I have installation disks with files dated >6/1990 and also a boot disk with some files >dated in 2/1991, I know that several bug fixing >versions exist, but Which is the last ?? > >I remembered it when I was reading all that >Windows Vista (LongHorn) stuff.

FORTRAN 77 on PDP-11

by jhfinexgs2＠compsys.to

I have been having some fun with Prime Numbers using FORTRAN 77 under RT-11 on a PDP-11. Since I rapidly run out of the capacity of 32 bit numbers (INTEGER * 4 NUMBER), I have started to use 64 bit values (REAL * 8 NUMBER) but the conversion routines leave a lot to be desired on output. When using F32.0, I can count on only about 15 digits of accuracy even though the values are often accurate to an exact integer. If needed, I can write my own conversion routines, but I though I might inquire if anyone knows of any libraries which are exact or better still, multi-precision libraries which can handle up to 128 bit integers? Can anyone Sincerely yours, Jerome Fine -- If you attempted to send a reply and the original e-mail address has been discontinued due a high volume of junk e-mail, then the semi-permanent e-mail address can be obtained by replacing the four characters preceding the 'at' with the four digits of the current year.

DEC Rainbow disks - help

by chrism3667＠yahoo.com

I just acquired a Rainbow with ~10 boxes of disks. Most are for DOS it seems, though some for cpm/86. Could someone explain the differences between the types of media meant to run on this puter, whether it has to do with os, or physical properties (soft sectored, hard sectored, RX50...). I also have access to a crate of pro 350 disks, and would like to know how to archive them. Is Teledisk or any other program useful for any of this? --- HOn3 at yahoogroups.com <cary_hocker at yahoo.com> wrote: > I've been pondering how to organize and store my old issues > of the Gazette.

Apple?

by robert＠irrelevant.com

Now I'm not an expert on these, indeed I know nothing at all about apples, but these look pretty weird to me - are they actually what they say they are, and really common? eBay item 5219329581 (expensive as usual, so no bids) for three linotype boxes, one of which has a disc drive with an apple logo on it. (Listing has some larger pics linked from it).

"New" RL02 on the way - how to power up?

by charlesmorris＠direcway.com

I have just purchased an RL02 and while waiting for it to arrive, I am wondering what to do for cleaning and lubrication before power-up. I don't know how long it's been sitting (indoors). I have downloaded the manual from bitsavers. I know there has been some discussion on this list recently but I think that was on the care and feeding of RK05's... Also, the seller tells me he can't get the pack out: >When I had the disk pack cover off, the release handle on the pack did >not release the disks and I did not want to force it. Does the drive >need to be powered on and is there a way to remove them without powering >it on? He does know about the shipping screws and will install them before Fedexing. So, what should I do first? thanks for any assistance. Charles

HP98780 monitor graphics PCB

by ard＠p850ug1.demon.co.uk

Does anyone here have an HP98780 (enhanced mono monitor for the HP9845B) easily to hand, and if so, could they do a little electrical test on one of the PCBs : Remove the top cover (4 screws), the screening cover under it (4 more screws). the 2 board hold-down strips (3 screws each), and the 2 screws holding the heatsink pillars from the rightmost board to the right side panel (directions given with the screen towards you). Pull this board out. When putting it back, put a little silicone grease on the ends of the pillars. In my monitor it's a 98780-66552 Rev B, I am particularly interested if you have that version... Anyway, the test : Check for continuity between pin 7 of U53 (this is a 74LS157 mux chip) and pin 2 of U55 (a 4116 or 4816 DRAM). The reason is that on my board, these 2 pins are not conencted, although the other outputs of that mux -- and of 3 other similar mux chips -- do go to the DIn pins of the RAMs. The 'missing' one would be bit 6 (of a 16 bit word), and I can't for the life of me think of a good reason why it should be different. I wonder if I have a cracked trace in the board somewhere (this is a multi-layer board so I can't check by eye). Thanks in advance -tony

ImageDisk Update (was TeleDisk Replacement)

by dwight.elvey＠amd.com

Hi Dave I have the need to tell the transfer program to ignore the first track/side 0 and only copy the remaining tracks. This is from an image that has fill for the first track. The reason for this is that the first track is FM and my controller does not support FM. The first track only contains some fixed information that is always the same >from disk to disk.

MicroVax 3600 free for the taking, imminent disposal! HURRY!

by jzg22＠drexel.edu

A digital MicroVax 3600 and its requisite heap of media has recently been trashed by the physics department at Drexel University. It is sitting in the hallway of the 7th floor of Disque Hall (building 12) at 3141 Chestnut Street in Philadelphia. The machine is intact, and according to someone I asked, it powered up and worked fine when tested 3 months ago. The machine includes an enormous pile of backup tapes, both spool and cartridge type. (the MicroVax 3600 has the RA-82 and TK-70 drives needed to read both types of media installed) The machine is the size of a narrow but tall washing-machine, and probably weighs around 300 pounds. Bring a Van or Minivan with the seats taken out! Also, the closest parking spaces are on the other side of chestnut street, (the nice little lot in front of disque has a gate blocking entry), so a small equipment cart would be helpful too. (I may be able to borrow one from one of the labs, so contact me!) Also included is a large pile of Tape backups and spool backups from 1987 through 1991 at least, which *MIGHT* contain some previously-thought-lost VAX-related programs (maybe the lost source code to the final version of ROGUE, or the missing parts of early UNIX sourcecode, perhaps... though I'm really just dreaming there.) I'm hoping whoever takes the machine takes the tapes as well (and shares anything interesting on them) but just rescuing the machine from imminent doom would be a major boon. I would take the machine myself, but I don't have the means to transport it and I don't have the space to store it. According to someone I asked, the machine is scheduled for disposal sometime either later this week or next week, so get it QUICK! If you need assistance moving the machine or dealing with Drexel security, email me at jzg22 @t drexel d0t edu (@t = @, d0t = .) Jonathan Gevaryahu lord_nightmare @t users d0t sf d0t net jzg22 @t drexel d0t edu P.S. Al Kossow: I'm sorry I never got back to you in february about the votrax manual, my life's been pretty hectic over the last 6 months. I'll email you over the weekend.

Believe me, I am aware of the limitations of the PC design, and the rudeness of some of the later designs... fortunately a lot of the guys here have older machines :-) I'm creating a replacement for Teledisk because: - I need to reliably backup and restore diskette images, and to post them for download (along with the tools to recreate them). - Sydex no longer supports TeleDisk, and is actively trying to get it removed from availability. - TeleDisk does not document the image file format, which makes it very difficult to explore other means of recreating the image if TeleDisk doesn't succeed. I am also creating systems to backup and restore images of disks which are not compatible with the PC controller, including several systems which work by serial transfer with the original host. This is just another piece in the puzzle.

Early Apple ][ board sells for $1K+

by vcf＠siconic.com

This was sold by the same guy that had the Apple-1 for sale (which he pulled today with no bids). http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=5790352907 Off the scale as far as price goes (maybe $500 on the high end, $1,081 is excessive), but the listing has good photos showing what an early Apple ][ motherboard looks like, including the breadboarding area at the front.

One of the things done when writing to a Floppy [it's done with all FDC chips if it's done at all!] is to deliberately twook the bit timing based on the bit pattern. The FDC provides a set of control signals (in hardware) and drives a bit of logic to intentionally smear the bits in time to allow for the media effects of close flux transistions. In most cses this is all hardware but usually the amount of precompensation is adjustable by both bit rate and a non FDC control register (back in the 1791/765 days). Some designs further modified the precomp value for the inner tracks (TG43) as drives didn't use TG43 or based on the deigners evaluation of bit crowding on the inner tracks might also alter the precomp timing to optimize flux transistion spacing. This is important as bits written to magnetic media tend to spread themselves out or crowd based on pattern when written closely. Hope this helps. >>Is this for a Cpro Disk-1(A) or something from the ground up? > >No, it for my ImageDisk utility, which is a replacement for >TeleDisk with a documented image file format - I want to provide >support for 8" drives that need TG43. Ok, then I take it that this is in a PC FDC that is based on the 765 core? I ask as a way to point out that features and functions that the base 765 chip have as implemented on an something like a Disk1A are very differnt in a PC. Largely the PC design truncates the interface from the 765 to something simpler abd often far less flexible. Some of the really late chips (post 37C65) do not even fully implement the full complment of interface signals and may only have limited access to things like precomp timing or worse those functions are "wired" by the chips designer to fit their view of what floppies are (IE: antique = 8" floppy, unsupported).

A minor Adventure in Vintage Computing

by hilpert＠cs.ubc.ca

So a friend and I headed out for a run today and on the way to the trails decided to take the shortcut across the lands of our friendly neighbourhood giant big-oil corp. oil refinery. This refinery was nearly 100 years old until it was mostly decommissioned and dismantled in the 1990s, although a portion of it still operates as a storage/transfer station for certain products. So after a little bushwacking and fence-hopping we were running down gravel roads between cement pads filled with weeds, cut-off steel stairways to nowhere, pipeline sections poking out of the ground and assorted other heavy-industrial detritus, while keeping an eye and ear out for the possible security-person-containing-vehicle to come bouncing over the hill. Off to one side of our route was one very old two/three story red-brick building that has yet to be demolished. This building looks like it could have been built in the 20s or 30s. We decided to take a peek. The big two-storey service door was open to the skies, but the building was still filled with equipment: giant motor/pump sets, engines/generators, steel walkways, pipes everywhere, peeling paint, all dead and quiet, just pigeons in the rafters and the occasional whoooosh from some pressure vent outside to spook us. My friend and I went upstairs into a room with the floor and shelves littered with crates, small motors, bits of equipment, cabling, etc. On one wall was a green & black, full-height, double-wide equipment cabinet, one door half open and large circuit boards visible in a rack. My brain started to tweek. In the mid-70s, as a high-school student, I and a few other students had a visit to the refinery one day to be shown the computer system that ran the refining operation. About the only thing I remember from that day is that it was a Foxboro real-time process-control computer that had been installed some years earlier. I had figured it was now long gone from when the refinery was decommissioned and the newer buildings, where the computer was likely to be located, were demolished. But there's not a lot of reason other than a computer system for circuit boards that large to be hanging around an oil refinery. Sure enough, the cabinet had a little "FOXBORO" logo up in one corner. Looking around a little more turned up a very large floor-standing video console with "FOX-1" in addition to the "FOXBORO" logo on it, a GE termi-net printer/terminal, and a sub-room packed with racks of what appear to be the I/O interface/drive equipment (where all the wires from the sensor/control points around the refinery terminate and are interfaced to the processor). Pulling a couple of the circuit boards from the main cabinet suggests the processor is TTL-based, although there were date codes from the early 80s so it may have been upgraded from the 70s. The console was quite cool, I speculate >from it's size and complexity it may have been an early graphics console that displayed process equipment/flow diagrams; date codes on ICs in it were still early 70s. Didn't see any disc or mass-storage device or even paper-tape I/O. Considering it's real-time application perhaps it functioned without a disk, just booted the whole system (from what?) at startup and survived in RAM. I don't know a lot about Foxboro, I believe they were a spin-off or startup company in the 60s that were early entrants into the (then small and state-of-the-art) area of computer-based real-time process-control for large industrial plants. They are one of those names you don't run across much unless you run in those circles. Additional comments about Foxboro and their systems from those who may know more appreciated. My friend finally dragged me out and we continued on our run into the forest with a little dip in the lake on the way home.

TG43 is mostly a relic signal of older 8" drives. Not all of them used it. Also it's supposed to be meaningless on read. I may add that more than a few designers also used demuxed TG43 to switch write precompensation in DD modes on 8" drives for better data reliability.

TG43 signal and the Nec 765

by dave04a＠dunfield.com

Hi Guys, I'm using a relatively modern 1/2 height 8" drive for my PC interface, which does not seem to care about TG43 - I left it unconnected, and it appears to be writing images just fine. It would however seem to be a good idea to support it for older drives and drives that need it... Question: According to the NEC 765 datasheets, pin 38 is LC/DIR, it indicates "Low Current" (TG43) during writes to inner tracks, and "direction" during STEP operations. It would seem that you might be able to simply stuff this signal into both pins 34 (Direction) and 2 (TG43) of the 8" interface, since the drive should not care about DIRECTION when STEP is not active, and it should not care about TG43 when WRITE is not active, and the two operations are mutually exclusive. However none of the information and cable diagrams I've seen indicate such a connection, suggesting that this might not work. Q: Can you simply drive both signals from the one source, or do TG43 and STEP need to be externally demultiplexed? As an alternative, I think I will also provide an option to generate TG43 via a parallel port output. Q: Should TG43 be asserted any time the drive is positioned to a cylinder >43, or should it be asserted only during WRITE operations when at a cylinder >43?

ImageDisk Update (was TeleDisk Replacement)

by dave04a＠dunfield.com

I've been working away at my ImageDisk utility, and have made a number of fixes, including some corrections to the sides/stepping detect logic which failed to properly detect some mixed density disks. I have added several new features, including improvements to the "Align/Test" function, and the ability to translate the data rates (This lets you do things like recreate DD disks read on DD drives on HD drives and vice-versa). This evening I finally wired up a cable to connect a double-sided 8" drive to my PC, and was very pleased to see that I was able to backup and restore several mixed density 8" disks with no problems - even a double backup and restore (backup of backup then restore) still matched the original and booted correctly. I have also created a first cut at my "Analyze/Merge" utility, this is a companion utility which: - Provides a detailed report of the track/sector layout and data formats occuring in the diskette image. - Can perform a logical sector by sector compare of two disk images, even if the binary layout is not exactly the same (usually due to different comment or problems detecting interleave). - Can merge two images into one, allowing you to take advantage of the fact that some PC's may read different sectors than others (one of my machines refuses to read the first sector on Cromemco disks while a second machine fails to read the last sector) - and create a complete image by merging them. It's late and I'm going to bed - in the morning, I will transmit the updated software to the people who already requested and received the first version (If you don't want to receive any more updates, please let me know). If anyone else wants to join in the fun, please drop me a line and I'll add you to my list.

device programmer recommendations?

by ethan.dicks＠gmail.com

OK... I've just about had it with this ancient B&C Microsystems UP600a - it _claims_ to support Atmel 22V10s, but I'm having no luck with that. It also seems to be unhappy with some modern JEDEC files - claming checksum errors and what not (on files generated and tested moments before from .PLD files). It does OK with Lattice 22V10s and AMD PALCE devices, as well as most 27(C)64s and larger, but it's getting harder and harder to find old GALs. So... I guess I have to find something new(er). Whatever replaces this will need to be able to program EPROMs down to 2732s at least (which should include 2716s), and 16V8 and 22V10 GALs. I'd say that accounts for 95% of what I need to burn (if I have to burn a bipolar PROM, I have ancient devices for just that task). So what device programmers do people here have that they'd recommend? I already have a dedicated PC attached to my current programmer, so I guess it doesn't matter what a replacement programmer needs to talk to - I'm already committed to supporting whatever box it needs to have (annoying as that is). Thanks for any recommendations, -ethan

vcf midwest stuff

by jwest＠classiccmp.org

Getting my travel plans together for VCF Midwest this saturday. I think I'm going to stay in a RedRoof that's about 5 miles east of the vcf location (I like redroof and the econolodge just didn't strike me). Since VCFm is one day, are people getting together for dinner the night before, or dinner the day of the show? Since it's only a 5 hour drive for me, if people get together the night before I'll head back saturday right after VCF. If people are going to get together saturday night, I'll head back sunday morning. I will be bringing the infamous red trailer, and exhibiting it in a booth at VCF. See the marks the fire/explosion left on the trailer! See the bullet holes from the police shooting at it.... *GRIN* But seriously - if anyone wants me to bring something particular up for trades, now is the time! Jay

"New" RL02 on the way - how to power up?

One of the shipping locks requires the pack to be removed. The early RL02s used a plate that was screwed in over the head to lock them and the later ones had a spring loaded lock that was active anythimg the pack was removed. So head lock can only occur with the pack out no matter what. This should be in the user manual. Allison

Entering 1N540 gets a listing for 1N540x. The data sheet shows a diode as described with the markings similar to that above, except that you seem to be missing a trailing character on each of the numeric lines. This is a series of 3 amp diodes with various voltage ratings. If you can't make out the training number, either go for the highest rating or measure the open circuit voltage that feeds the diode. Hope this helps... CRC

I've always operated on the principle that for diodes, current rating is relative to physical size.

The programmer manuals have the basic information. I have 14 page Application Note (circa 1985) that gives all the details on how to write a driver program. You could send the commands >from a terminal emulation program then send the data. The baud rate limit on older Data I/O programmers is 19.2k. (some are limited to 9600). It goes as low as 110 baud so you can use an ASR33 with paper tape. The interface is RS-232 with hardware handshake (flow control).

OMG! This is a 24 bit computer that Bob Supnik knows a lot about. It has an interesting history, started out as something for the military and Foxboro bought out the production run. Foxboro switched to DEC for their later products. I have the docs on bitsavers http://www.bitsavers.org/pdf/foxboro This machine needs to be saved, if that's possible.

PDP-8s and -10s

by aek＠bitsavers.org

>>DEC through the 'golden age' didn't go after that market. They tried to >>target scientific rather than corporate computing. > >One of the oddities is that the 36bit machines the 10s/20s were well >known for their timesharing with huge nubers of users. And they did put effort into front-end terminal concentrators on the later models of those systems. TOPS-10 had a significant influence on the user interfaces of some of DEC's smaller operating systems (RT-11 and RSTS for example), as well as CP/M. Google for discussions on alt.sys.pdp10 for why this wasn't true for RSX and VMS. I suspect that the driving force for tools (esp in TOPS-10) inside DEC came about because much of the software development inside of DEC for other CPU families until they converted to VAXen was done using cross-development tools on their internal timesharing systems (MACY11, etc.) and because 10's were THE machines to have in universities (MIT, CMU, etc, etc) if you wanted something that had a lot of good tools for a moderate amount of money.

Does it support something like XMODEM/YMODEM/ZMODEM/Kermit on the terminal port, or is an ASCII terminal not really sufficient, i.e., maybe they can only use a terminal to control mass duplication, but initialing image loading still requires a Losedows box?

This means that you can't just play back the signal written. The write signal has compensation for the timing shift caused by signals being close together on the disk surface. This tends to alter the edge timing. This is the information that you are trying to recover or play back. The sampling systems used to read the data back would not work well with the unprocessed write data going into them because of the compensation used. You'd need to provide a filter that is the equivalent of the writing and reading of data through the disk. Then you'd need to find the leading edges and generate the pulses that are read. I would say that 8X to 10X is a reasonable sampling rate but you'd still need to process the data before sending it back as read data. Dwight

Release Software to the Public Domain?

by marvin＠rain.org

A friend of mine passed away last week, and I am in the process of getting all the classic computer stuff from his house. Somewhere in all of this I am told that he wrote quite a few utility programs for CP/M. While I don't think it would make any difference, the executor of his estate is willing to sign a document stating that anything he wrote is now in the public domain. Question; what kind of document is available to do this? BTW, so far I've collected at least half a dozen Kaypros, one Osborne, and a number of others. I will be going over to start on the garage in a few minutes.

Post/pin combination...

by wh.sudbrink＠verizon.net

I just got the two Sol enhancement boards I recently won on ebay. They appear to be designed to integrate into the Sol mainly via the removal of a number of chips on the main board and plugging the upgrade boards into the sockets. To accomplish this, the boards have a large number of post/pin parts soldered onto the boards with the pin ends pointing down. On one board, two of the pins are broken off. The parts are gold plated, about 2cm in length total. The post part is about 1.2cm long and a little less than 1mm in diameter. Then, there is a short section that looks like what you would expect a pin from a quality machined pin dip socket to look like if you took it out of the plastic. It is about 4mm long varying diameter between 1.5mm and 2mm. Then comes the pin itself about 4mm long, less than .5mm in diameter. I can't seem to find a source for these. Any ideas appreciated, Bill

On the write side it is a pulse to the write amplifier. On the read, it is a pulse indication a transition at the head. The pulse width is not important on the read but does have a min/max. Write pulses need to be the correct width to tighter tolerance. Time between pulses is the most important element. But, yes, digital differential signals. Dwight

disk versus disc

Curiousity for the day - is there any difference between the use of disk and disc when describing floppy drives, hard drives etc.? The majority of people seem to use disc, but the use of one or the other doesn't seem to be a regional thing.

ImageDisk - need info on Adaptec 1542CF

by dave04a＠dunfield.com

One of the guys trying my ImageDisk program is using an Adaptec 1542CF controller - he can read disks fine, however when he tries to write them, it gets an error during every write sector command. The status registers reported ar: SR0: 41 SR1: 04 SR2: 00 According to the NEC 765 datasheets: 41 means "Abnormal Termination of Command" "Execution of command was started, but not successfully finished" No other error indicators 04 means: "B3: Not used, this bit always low (0)", No other error indicators 00 means: No error indicators Looks like the controller in the Adaptec is using B3 as an error indicator, however I do not have any information on what this means ... Does anyone have technical information on the Adaptec controller and can tell me what this bit means?

Sage II computer

by frustum＠pacbell.net

So yesterday (or was it the day before) I won the following Sage II computer on ebay: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=5218919241 The seller wanted $35 for shipping, but being local, I knew I'd have an advantage since I can just pick it up. I never used one, but I recall them as being pretty sexy for the time. The machine comes with no documentation. Fortunately, even though the auction didn't mention disks, the the two floppy drives have whatever is necessary to boot into UCSD p-system pascal. I've written a fair amount of Pascal, including my own Modula subset compiler, but it wasn't using the P-system. I've found some online references and I've ordered a couple books on it. Once I figure out how to, I'll make copies of my two very dusty and grimy, but working, boot disks. If anybody else on this list needs the same, I'd be happy to make a copy for you too. Just let me know. EBay searches have not turned up any manuals for this machine. Other O/Ss other than the p-System were used by this machine, eg, CP/M 68K. If anybody has docs, software, or pointers to same, I'd appreciate references to it. All in all, a good $22 ebay purchase. Thanks.

Although all the "technical" answers others have given are likely correct... I really suspect the majority of modern computer users use the terms because of the following: Disk = short for diskette, refers to floppies, and when a hard drive is called a "disk" is used for that as well simply because that is what floppies were called at the time hard drives became cheaper and more mainstream. Disc = CD or DVD. Not short of anything per se, but is taken right off the offical Compact Disc logo. For whatever reason, Sony et al decided to use "disc" for CDs. That is the way the packages and logos are written for CDs and now usually for DVDs as well. Nothing more complex or deep rooted then that. People use the spelling they see on the packages in front of them. Floppies almost always say "Disk" and CDs always (it is part of the offical logo) say "Disc". From there, users interchange them from time to time because they simply don't know what is correct or even why each are the way they are. -chris <http://www.mythtech.net>

11/45, sick or not?

by jwest＠classiccmp.org

I finally allocated another day to spend on the 11/45. Unfortunately, I must say I'm not sure if it's sick or not, hopefully someone can help. First, none of the blinking lights programs I've seen blink the lights. I can store and retrieve the program correctly, but when I put 1000 on the switches and hit load address then run, it goes into run mode but no lights blink (with any display switch setting). Halt makes the processor halt. Here's what I did: 1000 005000 start: clr r0 1002 005200 inc r0 1004 006100 loop: rol r0 1006 000005 reset 1010 000775 br loop On this program I put 1000 in the switches, hit load address, then run. Address lights constantly show 1010, Data lights are blank, and the Run light is on. Data Paths setting shows 0, bus register setting shows 5, uaddr shows 177774. Another test... if I store a 5007 (clr pc) in location 0 and start the processor at location 0, the address lights show all 0's, the data lights show 2, and the following lights are lit - pause, master, kernel. I also tried this with location 0 set to 777 (br .) and get the exact same results. More info... just after power up, the address lights show 20, the data lights show 21043 (data paths). Master & Kernel are on. The uaddress setting shows 177570. So... I decided to go back to basics and check all the power points at the pins on the backplane. Here's what I found: A02A2 0 A06A2 4.931 A10A1 4.931 A26A2 4.931 A19A2 0 A16A2 0 A21A2 0 E02B2 -15 A17V2 0 A22V2 0 A17U2 0 A22U2 0 F17C1 0 E15A1 16 E01B1 9 Since my machine only has regulators at B, C, D, E, and F, I suspect the 0 volt readings above are ok. All the 5 volt test points have a very clear .2v sawtooth pattern (which looks fairly smooth at 5v). Since one manual says the ripple limit is .15, and another manual says the ripple limit is .20, I suspect I'm ok there. The ripple on -15, 16, and 9 I can't see any noticeable. And by the way... the cpu cardset was borrowed from another listmember and tested before I received it so I don't think it's something wrong with the cpu cardset itself. Any thoughts? Jay West

"Response" from seller with the "Apple-1"

by vcf＠siconic.com

Here's the response I got from the seller who listed that plywood box with keyboard mounted to it: "I am so sorry for the late response. I did not even know about this ebay messages, I have 53 messages now to go through. I thought they all went to my email account. But I guess only some do. Again, I was not trying to dodge your question. I have missed many about 90%. I was not aware of this change in yahoo email." That's his "answer", which I really appreciate because, you know, I would really be bothered if the guy tried to dodge my question. Of course, this doesn't explain how he somehow didn't miss the 5 questions he did respond to which are displayed on the auction page (see for yourself: item #5213140640). BTW, I received this same exact message twice in response to the two inquiries I submitted to him, so I'm sure the other 53 questions got "answered" in a similar fashion. Another fine example of why I can't stand eBay. -- Sellam Ismail Vintage Computer Festival ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintage.org [ Old computing resources for business || Buy/Sell/Trade Vintage Computers ] [ and academia at www.VintageTech.com || at http://marketplace.vintage.org ]

IBM AT Drive Types

by richard.beaudry＠gmail.com

Hello all, Believe it or not, I couldn't find this on google, so I humbly submit it here.... Does anyone have a list of the built-in drive types from the original IBM AT? I'd like the drive number, heads, cyls, and capacity if you have the list. The setup program on the diagnostics disk only lets you pick a type, but it does not tell you what the choices are... Of course, I know that later computers came along with BIOSes that let you see the drive types instead of picking one out of thin air, but I don't know if these followed the AT choices... Thanks! Rich B.

Latest round of Pioneer Planetary Society data analysis stuff on slashdot

by aek＠bitsavers.org

Since Sellam just talked to someone about this.. Here is the only useful bit of information in the discussion: --- I talked to the guy who used to run Pioneer... ...and the situation is as follows: * The data used to be stored on magnetic tape. When the tape started deteriorating, all the data was archived off onto then state-of-the-art MO disks. * The machine used was a MicroVAX with a DEC RWZ21 SCSI MO drive, which is apparently quite rare. The disks are 128MB each. * For Pioneer 10, there are 155 disks, making 19840 MB of data. * For Pioneer 11, there are 217 disks, making 27776 MB of data. * Each disk takes about 10 minutes to read to the MicroVAX, and then more time to move across onto a real computer, of course. I would have happily volunteered to spend a couple of days swapping disks in order to salvage all this lot, but alas, I'm the wrong side of the Atlantic. The guy in charge has recently been made redundant, and he was desperate to find someone to hand off all this to... but there's incredible beaurocracy. (I gather all the data was actually supposed to have been destroyed some years ago, but through some 'oversight' hadn't been.) Alas, I don't have permission to publish his address, but I'll put him in touch with the Planetary Society on the off chance he doesn't know about this. Interestingly, for years he ran the Pioneer spacecraft off a Mac Quadra 950! Check out the screen shots [nasa.gov]...

Decitek Reader and Remix punch

by wacarder＠earthlink.net

Today I obtained a Genrad 1797 programming station. It consists of a PDP-8a, 3 RK05s, a Decitek paper tape reader, a Remix paper tape punch, and a Genrad interface unit. Also with the system is a DecWriter III and 3 RK05 16 sector packs, as well as an alignment pack. I have not begun to study the system yet. Quick questions: 1) The Decitek reader appears to have a serial (EIA / RS232) interface. Can someone point me to some documentaion on how this might be interfaced to a PDP-11? 2) Same question as #1, but for the Remix paper tape punch 3) What were these GenRad programming stations used for? 4) What is the purpose of the GenRad 1795-3010 interface unit? BTW, the system looks to be in good condition and was said to be running before it was decomssioned just a few months ago. Once I get a 30A 4-prong receptacle installed for it, I'll fire it up and see what it's all about. There is a boot pack for it. Any help or pointers on where to find information on the Decitek reader, Remix punch, and GenRad equipment in general would be greatly appreciated. Thanks, Ashley

HP 98xx manuals

by aek＠bitsavers.org

I guess you don't have the manuals for this. AFIK I have the full set of manuals for BASIC 5.1 along with a bunch of other useful related HP manuals such as the HP 9826/9836 and HP 9000/300 Series Computer Installation manuals, various peripheral configuration manuals, BASIC 2.1 and 3.0 manuals, HPL manual, Pascal manuals, Self-Study Guide to Instrument Interfacing using HP Basic, FSD Customer Engineering Manual and more. This stuff needs to be made available to the everyone. Al has asked about borrowing the stuff and scanning it and I've told him that he can but we haven't done anythng to make it happen yet. But it's about time that we did. How about it Al? Do you have time to do this stuff yet? --- I'll make time to get it done. I have a couple of other manuals to get on line (like the other PASCAL manual and the 9836 service manual) Was talking to a friend of mine today who makes a little Ubicom board and I suggested he implement an HPIB interface on it and implement enough of a emulator to provide an HPIB peripheral to Ethernet interface. Then, you could have a box on the net simulate the rest.

disk versus disc

by Watzman＠neo.rr.com

Re: Curiousity for the day - is there any difference between the use of disk and disc when describing floppy drives, hard drives etc.? I just wondered if one is technically right and the other wrong when it comes to computing... ***** The answer is that there is a technically right and wrong usage and difference between disk and disc. DISK, with a "K", is technically correct for magnetic media (e.g. floppy disk) DISC, with a "C", is technically correct for optical media (e.g. Laser disc, CD-ROM and DVD discs)
