ROLM PhoneMail System Info?

by bill_r＠inetnebr.com

I have been offered an IBM/ROLM phone mail system. I'm curious if it's something standard that's been put into use as a phone mail system, or if it's some weird proprietary thing. It's about 4 feet high, and about 4' x 3' or so. It runs on 220VAC at what appears to be many amps. Inside (the parts I could see - it's still in use at the moment) were several cards in slots, a physically large hard drive, a monster power supply, a tape drive, and some other bits. What I could see was: Priam P/N 330352 hard drive ROLM 40311 Phone Mail System Voice Compression I/O Card 8 Channel Voice Card AP 4MB RAM 41508 System Processor II 41002 Unless it's to go to the junkyard, I need to let them know by Friday (tomorrow) sometime. The hard drive is making "bad bearing" noises, and the voice mail has started to "stutter". They found a newer box to replace it that's about the size of a bread box for less than a refurb hard drive would cost. I'm not sure what I'd do with it, but if it's got anything useful in it, I'd try to salvage it for someone else, if they can arrange shipping. Bill Richman

Tandy DMP 430 Wide Printer Available

by dlw＠trailingedge.com

I'm sorting through and clearing out a few things but first I have a Tandy DMP 430 printer. It's one of the 132 col printers. It also has one of those noise-reducing printer cabinets. It's pretty big and heavy so free to anyone in the Houston, TX area that would like to pick it up. I guess I could ship it if someone really, really wanted it but it would be costly I think and a pain. I picked it up with a bunch of other stuff and have never tried it out so it's as is. ----- David Williams - Computer Packrat dlw(a)trailingedge.com http://www.trailingedge.com

Another tech legend for discussion!

by netsurfer_x1＠hotmail.com

I have another tech legend to be dicussed: It is generally believed that the Apple Lisa is what spurred Bill Gates to create Windows. But recently I have read something that says it was *not* the Lisa that inspired Bill Gates, but that it was VisiCorp's VisiOn software (remember that, yeah, me neither!). So my question is: Which one was it? Was it Lisa or VisiOn? ________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com

Apple II keep list

by paulrsm＠ameritech.net

---------- > From: John R. Keys Jr. <jrkeys(a)concentric.net> > > Look for Woz editions and rom 3. You can take the Woz cover off of any IIgs and put it on any other IIgs. This is important for collectors who desire absolutely factory original equipment. Add to the list any non-Apple brand IIgs memory card. The Apple card can only hold a maximum of one megabyte, but other brands can hold more, some up to a maximum of eight megabytes. Some IIgs cards use weird memory (i.e., SIP) so you may be able to use the chips in another same card that is not filled.

OpenBSD 2.6 on Sparc

by technoid＠cheta.net

I have a SparcStation 4/330 (sun4 architecture) running OpenBSD 2.6 on a 540mb drive. I have a few questions relating to fleshing out the original install: Where do I find descriptions for each package/port? How do I get PKG_ADD to resolve it's own dependencies? (goes to above question). I would like to install KDE or Enlightenment or some better Gui than X11R6..... I have Solaris 2.4 (sparc) installed on another drive (triple boot system - netbsd, openbsd, solaris) and so have the libraries the Compat_sunos manpage says it requires except for LIB5. Do I need a later version of solaris in order to get the libraries I need to run solaris dynamicaly linked applications? The mans are not specific enough for me to get there from here. The goal is to run Netscape for Solaris 2.4 under OpenBSD 2.6. I've cp'd the libs to the correct dirs according to the manpage but netscape fails to load with a trap almost instantly. I have updated my solaris 2.4 for the bind issues relating to netscape and other apps and those new libs are in place on my obsd drive in the right place but to no avail. In particular I would like to know why following the directions in the manpage results in my solaris 2.4 partition being no longer bootable. Solaris dies with several errors regarding Lib.so suchandsuch not being readable and dies. I only mounted the solaris drive for read to copy the files and each time I do that the solaris partition won't boot anymore. My guess is permissions being changed because the solaris partition is mountable under OpenBSD even after it will no longer boot, all files are there in the right place and OBSD reports the solaris partition as clean. What is happening here? Some equipment info: sd0 is at 0,0 540mb Openbsd Sd1 is at 1,0 540mb NetBsd 1.4.2 (gotta use 1.4.1`s miniroot to install on Sun4! Sd2 is at 3,0 1004mb Solaris 2.4 (can't boot from cd so I use TomsRTBT on my klone and dd an image then install from the image'd hard disk..... Hey, it works. Video is a CG6 daughtercard on my sparc's mainboard. X runs fine. I do have a cdrom drive that is not bootable but otherwise runs fine for all three operating systems. Thanks for your support.

I only have one IIc+, but it was $15 with an external 5.25" Laser-brand floppy drive, two Imagewriter Is and a smallish (9"?) mono monitor and stand, docs but no software. I'd wanted a IIc since I wrote kiddie-software under the Software Productions/Reader's Digest label in high school ("Micro Habitats", "Micro Mother Goose" and "Alphabet Beasts and Company" were our big titles). That's why I only have DOS 3.3 disks and the odd Infocom title; I haven't used an Apple on a regular basis since 1984. Now that the hardware is ultra-cheap, I can make up for all those lost years. -ethan ===== Even though my old e-mail address is no longer going to vanish, please note my new public address: erd(a)iname.com The original webpage address is still going away.

Great Finds

by steverob＠hotoffice.com

Hey gang, With some help from Joe Rigdon, I found some really cool stuff this weekend. Located two complete HP 9000/832 minicomputers. After tinkering around for a few hours, I found one of them has a bad CPU and 3 of the 8 (total between two machines) hard drives had failed. So, between them, I managed to build a complete working system with some spares left over. What kind of tapes does the built-in drive use? The find-of-the-day however, was a HP 7980XC 9-track tape drive. Found this beauty in a dumpster at one of the junk dealers. It's god a few minor scratches on the front cover but, otherwise is in extremely good condition. The total asking price 5$. Anyone got spare DOCs for it? I hooked the tape drive up to one of the 832s but, just can't get it to work. Whenever I try to cpio or fbackup to the tape, the drive will try to work but, eventually gives a write error. The same thing happens with my other tape drive (HP7980) which I know is good. So, I suspect the problem is with the drivers, or configuration, or possibly me :-) If anyone can give pointers as to how to make it work, I'd sure appreciate it. See Ya, Steve Robertson <steverob(a)hotoffice.com>

Networking Apple IIc or IIc+

The ROM 03 had different hardware (more memory on the motherboard, for example) and you cannot convert an earlier version to a ROM 03. A ROM 03 is considered the best if you are going to run GS/OS, the Apple IIgs 16-bit native operating system. I am happy with my ROM 01 since I use it like an 8-bit Apple IIe. Paul R.

Tim's own version of the Catweasel/Compaticard/whatever

>You write about this experiment with considerable confidence in your result, >considering that you haven't any conventional hardware for dealing with this >stuff. There must be something about your results that gives you the >confidence to proceed. What might that be? Are you getting verifiable >results, i.e. data that makes sense like ascii files, etc? Yes, ASCII (and EBCDIC, remember I'm recovering floppies originally written in the early 70's) files that make sense. I think, Dick, that sometimes you make this seem harder than it is. Many of the data formats are readable (in hardware) with something as simple as a one-shot and a UART. >Sampling and recording the analog signal might prove disappointing. The >data will be much harder to recognize in its analog form, particularly on >the inner tracks on a noisy diskette or drive. True, but the analog circuit would also be easy to simulate electronically. Just a few coupled linear and nonlinear differential equations! Tim.

(Other than the 128K*8 SRAM, all the other parts were literally >> purchased from the local electronics shop. Heck, most of the chips can >> be bought at Radio Shack!) Total cost for the chips in my buffer is >> about $30.00, about half of that in the SRAM chip. >I sympathize with that, but for those of us who are much better at software >than hardware, something off-the-shelf is a big plus. OTOH, something I can put together on a Sunday afternoon with parts I bought at Radio Shack is an even bigger plus for me :-). It's not like my buffer uses any complex electronics. It's all perfectly- standard TTL parts and a SRAM chip, and it's currently residing on a pretty randomly wired solderless breadboard so you don't need any fancy construction techniques. Except for the capacity of the SRAM chip, this is all quarter- century-old technology. As Chuck pointed out, maybe the fact that this is quarter-century-old technology put together with quarter-century-old construction and design techniques makes it less accessible to some of the younger members of this list. Maybe the way to make it more accessible to them is to put the circuitry on a CPLD, I dunno, I think it's fine as it is. I suppose there *are* folks who might be interested in using such a device who don't know which end of a soldering iron to pick up, but a very valid point is that I built this without even touching a soldering iron! And the fact that I built it without even drawing a schematic first would tend to implicate the design as being on the naively simplistic side, too :-). (I still gotta draw that schematic up for you guys...) >Another point to note is that the Catweasel samples at 7 or 14 MHz (software >selectable).

I once got in a small argument with some other members of this list about AC circuit design of MFM vs FM data recovery circuits. IIRC, they were insisting that MFM did come "for free" if you had the frequency response necessary for FM at half the data rate. My point was that it wasn't the max pulse frequency which made life difficult, it was the phase response (finding where the pulse occured in the window) that was the tough point. >, and I had to use an extra heuristic >to make them readable at all.

Yeah, well, with my circuit if you don't like the sample rate, you buy a different off-the-shelf oscillator in a can and plug in. If you now need more buffer RAM, you plug in a second RAM chip and wire it up. That's IMHO the beauty, but maybe a software-only hacker doesn't see that. Tim.

Great Finds

by dhquebbeman＠theestopinalgroup.com

All I can find out about this drive is that it's a streaming unit. Is this another repackaged Cipher F880 Microstreamer? If so, then yes I just downloaded the complete Volume 1 docs on Saturday; they're in both .TIFF and .PDF format. If the HP is a different beast, well, good luck... somebody's likely got the docs. -dq -----Original Message----- From: Steve Robertson [mailto:steverob@hotoffice.com] Sent: Wednesday, July 05, 2000 10:25 AM To: classiccmp(a)classiccmp.org Subject: Great Finds Hey gang, With some help from Joe Rigdon, I found some really cool stuff this weekend. Located two complete HP 9000/832 minicomputers. After tinkering around for a few hours, I found one of them has a bad CPU and 3 of the 8 (total between two machines) hard drives had failed. So, between them, I managed to build a complete working system with some spares left over. What kind of tapes does the built-in drive use? The find-of-the-day however, was a HP 7980XC 9-track tape drive. Found this beauty in a dumpster at one of the junk dealers. It's god a few minor scratches on the front cover but, otherwise is in extremely good condition. The total asking price 5$. Anyone got spare DOCs for it? I hooked the tape drive up to one of the 832s but, just can't get it to work. Whenever I try to cpio or fbackup to the tape, the drive will try to work but, eventually gives a write error. The same thing happens with my other tape drive (HP7980) which I know is good. So, I suspect the problem is with the drivers, or configuration, or possibly me :-) If anyone can give pointers as to how to make it work, I'd sure appreciate it. See Ya, Steve Robertson <steverob(a)hotoffice.com>

A co-worker and I spent 6 months writing a DOS 2.0-compatible file system for our own application which contained its own home-rolled multitasker; we had to write the file system because the DOS file system calls were (and through at least 3.3) were not serially-reentrant. Even then, the performance was so poor (we had just moved to deploying on iAPX286 machines) that we ditched the full-task model and created what we today would call "threads", although we simply called them lightweight processes back then. The context switching you're referring to revolves around switching some data structures, such as the file handle table; but you have to wait until a file system call is done before you can swap to the next task. Not useful when (like us) you're developing real-time software. As an aside, this was for the last firm for which I worked as a programmer; I left in '90, and dropped in for a visit in '95; at that time, they told me the system I'd designed was running in a DOS box under the Alpha-release of Win95 and was beating a comparable application running on a VAX. I felt very good that day... -doug q

I _had_ assumed the IIc+ has a Z8530 SIO chip inside. If that is _not_ the case then it's probably some flavor of ACIA 65xx or 68xx UART. The Z8530 is a great chip, found in Suns, Macs, COMBOARDs ;-) For LocalTalk, Apple runs the chip at ~230kbps, IIRC (tangentally, I have the Byte article unveiling the 128K Mac where they describe a "slotless" architecture using virtual slots off the serial port in a manner that sounds like what USB has finally brought to the masses). I do not know if a 4Mhz 65C02 can pull data off the chip fast enough to be practical. We used to use a 4Mhz Z8530 w/an 8Mhz 68000 with plenty of cycles to go around. > The idea would be to plug a PhoneNet adapter into a IIc/IIc+ serial port, > Now add a second IIc/IIc+ to the "network" and run a normal terminal > program on it.

Tim's own version of the Catweasel/Compaticard/whatever

by CLASSICCMP＠trailing-edge.com

>First of all, what, in the sampled bitstream tells you that a bit is "flaky" >or in any sense questionable? If it's different on multiple read passes, then it's flaky. If it's different when read on different drives, then it's flaky. But since this particular circuit samples the data after it's gone through the AGC and discriminator section in the drive, you can't look at an individual pulse and say that it's flaky. A circuit which recorded the analog signal from the head (or one of the preamp stages) would be far better for spotting flaky bits. > Since your sampler is working at a harmonic >of the theoretical data rate, you should be able to find anomalies easier >than one who's sampling at some other frequency, but these frequencies >aren't terribly precise because of mechanical variations and the general >fact that even closely specified crystals still aren't identical in >frequency. I don't think there's any magic that results from me working at a harmonic of the nominal data frequency. I could be sampling at 14.353773 or 3.5798 or 4.00 MHz and it's all the same, because none of them are "locked" in any way to the actual data rate. >How can you tell that your error correction is of the bit that caused the >error? There are, in every sample, some bits that will fix the CRC that >weren't necessarily wrong in the first place. True, but if there's a flaky bit then it's more likely to be causing the CRC error. If I go to the two flaky bits in a sector and fiddle them by hand, and all of a sudden I match the CRC, then we're doing pretty well. Keep in mind that even with more-bits ECC's there are also multiple ways you can fiddle bits in the data section and still match up with the error correcting codes. > Since you're looking for read >errors not necessarily written incorrectly, I assume you have some means for >making a decision?

Again, I look for bits that read differently on different read passes, and fiddle those by hand. > How do you decide where the bit boundaries really >are? I've got a "software PLL". It synchronizes on both data and clock pulses, and when it senses that it's seriously out of whack it can adjust more rapidly than a traditional one-time-constant hardware PLL. > How do you interpret the chaos in the write-splices? I pretty much ignore the chaos. I've developed some graphing techniques that help me decide where the write-splices are for a particular low-level data format. (Remember, I'm mainly concerned with hard-sectored formats which vary a lot from one controller to the next. Many have *no* address information recorded magnetically.) >Do you operate your sampler in parallel with an FDC in order to ensure that >you've gotten a sample that's readable by the FDC? No, mostly I'm looking at oddball hard-sectored formats that a normal IBM3740-derived FDC chip can't handle. And if I had the real hard-sectored random-logic controller, I wouldn't need my analyzer circuit :-). >Have you, in general, considered using a PLL e.g. 4046 or some similar >device for generating a precise multiple of the detected data rate and >"tracking-out" the mechanical influences of your drive on speed? I thought about it, but I don't think it's necessary. My 8x oversampling seems to be just fine for both FM and MFM data formats. When I start making the descriptive web pages this weekend, I'll show some graphs that indicate how I find write splice areas and track data rate frequency from my analysis software. (I do no analysis in real-time, it's all done post-acquisition.) Tim.

Dwight, I think you're confusing CRC (Cyclic Redundancy Check) with ECC (Error Correction Code). CRC is very good at detecting errors, including bursts of errors that might slip by simpler checks, but AFAIK tells you next to nothing about where they occurred. ECC tells you enough to correct small errors. I've not heard of anyone using CRCs for correction (not directly, anyway). > As I recall, > CRC32 can fix a single error burst up to 12 bits long.

What this > means is that if you have a burst longer than 12 bits, it is > more likely that the errors will appear to be outside the data > block than within the data block. Although disks use the V41 polynomial (X^16 + X^12 + X^5 + 1) not CRC32. > All errors that happen > within a 12 bit window are 100% correctable. Depends how large the data covered by the check is. For amounts of data larger than a certain size (dependant on the number of check bits and the algorithm used) there are several errors that will produce the same change in the ECC or CRC. So the window size is meaningless unless you also specify the data size and number of check bits. -- Pete Peter Turnbull Dept. of Computer Science University of York

This should do it: (sent to the list for everyone's benefit) DATELINE: San Diego, CA March 3, 1986 Word Count:440 Celerity Computing 9692 Via Excelencia San Diego, CA 92126 619-271-9940 CELERITY SIGNS MAJOR OEM PACT WITH LEADING EUROPEAN DISTRIBUTOR SAN DIEGO, March 3, 1986 -- Less than a month after Celerity Computing's introduction of two new superminicomputer design systems, the company has signed a $3 million agreement to supply OEM configurations of the systems to GEI Rechnersysteme GmbH, Aachen, West Germany, a leading European systems house and distributor of of computer systems. Under terms of the two-year agreement, Celerity equipment, including its proprietary 32-bit ACCEL (TM) processor, will be incorporated into systems GEI manufactures and distributes to end-users in industrial automation, engineering design and simulation, and communications. GEI sells both customized and turnkey solutions throughout West Germany and Switzerland to customers including BMW, Audi, Volkswagen, Porsche, Ford, Philips and the German government. "This agreement with GEI represents not only a significant expansion of our presence into the European market, but also a major third- party endorsement of the performance and capabilities of our systems in the mechanical engineering arena," said Stephen Vallender, President of Celerity Computing. GEI installed more than 400 computer systems in 1985. The company is 50 percent-owned by AEG, which recently was acquired by Daimler- Benz/Mercedes. "We want to deliver the highest-quality, top-performance computer products to our customers," said Michael Emrich, President of GEI Rechnersysteme. "We ran benchmarks with all the players in the supermini and CAD/CAM markets, and Celerity clearly beat the others in performance and price." Celerity's UNIX (R) - and reducted instruction set (RISC)-based supermini design systems are the fastest and most powerful office_ environment systems in their price class for engineering and scientific applications. The Celerity C1260, introduced in January, 1986, is a dual-processor system with a benchmarked throughput of 6.15 million Whetstone instructions per second (W/MIPS). It is priced at $110,000 for a functional system configuration. The mid- range C1230, also introduced in January delivers 3.25 W/MIPS for $75,000. Both are deskside systems, allowing engineers to complete design tasks and compute-intensive analysis operations without off- loading to more expensive, remote computers. Three-year old Celerity Computing delivered its first computer system, the C1200, in November 1984. The company has installed more than 60 systems in leading corporations, research centers and universities throughout the United States. Its supermini design systems provide advanced design and analysis capabilities to professionals in a variety of fields, including automotive, manufacturing, aviation and aerospace, molecular modeling, animation, and research. ________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com

(Fwd) [HP3000-L] Old 960 out to pasture.

by ss＠allegro.com

For anyone out there with an HP 3000/960 (or 960 or 980), or an HP 9000/860 (or 850 or 880?): ------- Forwarded message follows ------- Subject: [HP3000-L] Old 960 out to pasture. From: Debus-David(a)AER.ARAMARK.COM Greetings All, I am finally decommissioning my old and trusty 960. I have gutted the chassis for of all usable boards. They are all available to anyone interested in spare parts for the cost of shipping. One hard to find item is a SCSI bootable CA. There are numerous FL cards and the usual HP-IB cards. I need to move this quickly due to floor space problems. First interested party takes all. Thanks ------- End of forwarded message ------- No...I don't know where he is! (Please don't flame him) Stan Stan Sieler sieler(a)allegro.com www.allegro.com/sieler/wanted/index.html www.allegro.com/sieler

Tim's own version of the Catweasel/Compaticard/whatever

From: Tony Duell <ard(a)p850ug1.demon.co.uk> >> That's so true! I was surprised to read in the spec's for my first ones >> (and last, by the way) that the capacitance between adjacent contacts is 5 >> pf, I don't remember much else about them. > >And that's probably being somewhat optimistic!... > >I have certainly seen microcontrollers fail to clock properly when >they've been used on these breadboards. Hang a xtal and the 2 33pF (or >whatever) capacitors off them and the strays will mess things up. Often it's not the breadboard but the crude oscillator circuit that was used. the basic osc used in theory should never work but crystals are less deterministic and don't know that. The side effect is hard starting and a slight offset from the marked frequency. >Since soldering is so much more reliable, and just as fast once you get >used to using the soldering iron, I don't see the point of said >breadboards. But anyway... Different issue. FYI I breadboard on a peice of cheapo copper clad AKA dead bug or as the RAH calls it "ugly" construction. Works well and the groundplane is hard to beat. Either name, you lay the bugs upside down and point to point wire them (solder, programming language #1). Copper is ground and everything else aint. Goes together fast and tends to be fast logic and UHF friendly. Allison
