Looks can be deceiving. That might be an HP-HIL connector -- does it have a picture of the corresponding plug with one or two dots on the cable, or maybe just the one or two dots? If so, it's HIL, and is there so you can hook up a Vectra HIL keyboard (as shipped with the real original Vectras that don't have alphabet soup after the word "Vectra") or an HIL mouse or an HIL monitor w/touchscreen. -Frank McConnell

>The main hardware used was an ALTAIR 8800A Computer >(INTEL 8080 chip). The software was an MITS Package >I Monitor, enhanced with JAMON (written by Jerry A. Ford, >MITS Program #117752). The synthesizers consist of 3 >identical voice circuits (pictured on the front of the >album cover). This is an Altair controlled hardware synth I take it? Now *MY* Altair Synth (pardon the ego!) was all done in software, with a simple 8-bit d/a converter on an i/o port. It used 256 bytes of a waveform (fundamental sin(x) plus some harmonics) that were stepped thru by up to 4 pointers at various rates and added up to get 4 part harmony. Took a lot of instruction cycle counting to get the timing just right and was worked up to where one could, with a lot of tedious data entry, type in a Bach invention (#8 - was on 'Switched on Bach') and have it play perfectly. Now, being a 2Mhz machine it sang bass and tenor mostly. Spent many a long night getting one together for a school software contest and the prof. gave the prize to a lousy serial auto-baud detector (probably because HE suggested it).

On topic: Serious static problem

by A_Finney＠wfi-inc.com

This is giving me fits. There's something strange with my minivan, that it generates a *ton* of static electricity whenever I drive even a few blocks. When I touch the metal of the door upon getting out, I get a shock that hurts all the way up to the shoulder. The real problem, and what makes this on topic, is that I use this vehicle to pick-up/transport my classic beauties everywhere. I'm terrified that I'm going to pick up that once-in-a-lifetime S-100 rescue or something and kill the guts with one of these lightning bolts. What I do now is keep a wrist-strap and a box of Bounce dryer sheets (don't laugh) in my jockey box. Does anyone know what could be causing this? Aaron C.

Blue trim was dropped fairly early - both the machines we had at school were black trim - as was the rebadged cassette deck with the lift-the-lid eject mechanism, the latter being replaced by the C2N. I had always assummed that 1000035 meant the 35th machine with the 220-240V power supply. > My PETs are 0014090 (small keyboard) and 0020272 (large keyboard).

Rubber cups or domes always in my experience give some sort of mechanical hysteresis when you press them. All PET keyboards I've used are smooth until they hit the stop. Small keyboard had little black rubber pads set into the plastic mouldings of the keys. >> The top 4 address lines are decoded on the mobo by a 74154 to give block >> select lines.

Only the lack of power. Flying lead from cartridge to 2nd cassette port is the usual solution AFAIK (it's what I did on my RAM expansion). No, I've never heard of ROM cartridges like this but I've met other things I think. ROM expansion usually went inside... >> When I added a 62256 to my 8K PET, I encoded the block select lines for 24K >> of RAM space and 8K of expansion ROM space (blocks 9 and A).

Tony Duell helped with one or two tips, I think. Such as, 65256 doesn't work, use 62256 instead. And the way of avoiding the need for inverters if you use the right sort of gate when re-encoding your address (but I may have failed to implement that). > Why do POKE and PEEK fail there?

It was a feature that was supposed to prevent inquisitive geeks disassembling the BASIC ROM between $C000 and (I think) $E7FF. The OS ROMs, above $F000, were peekable, though, as was the I/O space in the E block. You could of course peek and poke the screen, $8000 - $83E7 inclusive. > I think *all* of the 6550s in that machine are duds, but I could move 4K > over from the working machine.

Scanning Fiche

by Innfogra＠aol.com

Zane; I just got in the whse two reader printers (dry toner) that print on plain paper. I buy and sell microfilm equipment also. If you wanted to rig a parts scanner to a Microfilm reader I have both parts too. However I would recommend a service bureau that could turn the Microfilm into CDs. You should get high quality documents that way. This should not be too expensive, particularly if you have a lot of pages. Archiving technology has pretty much moved to CDs. Service companies that used to film documents nowadays image documents to CDs. I have one of these companies interested in purchasing one of the reader printers I got in. I expect to be talking with him tomorrow. I will ask about getting MF data into the computer, costs and turnaround. Paxton

Scanning Fiche

by adavie＠mad.scientist.com

I guess I'm being a bit whimsical. But I was intrigued and impressed with the recent NASA super-resolution images, generated from the Pathfinder pictures. The basic gist of it, as far as I understand it, is that given an unchanging target (the fiche, for example), you can build up a much higher resolution image than your scanner is capable of simply by making multiple scans and processing them together. Each will be offset from the others by fractions of a pixel (assuming you move the fiche ;). Software to combine multiple lores images into a highres image would be fairly straightforward. I guess the more scans you do, the better resolution you can obtain. Yes, its tedious - but should work.

RD54 on an RQDX3?

by cfandt＠netsync.net

Hi gang, I will buy an RD54 to replace that ornery RD53 on my MVII (recall we discussed the problem of the RD53 drive heads sticking a while back?) I just want to make sure that the RQDX3 EPROM versions on the controller will handle an RD54 drive. The version numbers are labeled as so: 285-E5 & 286-E5. I'm buying a spare RQDX3 controller board with these version numbers. The RQDX3 in the MVII have an older version # which I cannot recall at the moment. Already searched Sunsite and Tim's Micronotes. Nothing about the 285-E5 & 286-E5 numbers shows up. Back in October there was a ClassicCmp thread regarding handling of RX33 floppies. No comment about RD54's addressed. Thanks for the help.

What's a Lisp Machine?

by hhacker＠gte.net

I spoke with Chuck Fry, an old friend who once worked for Symbolics, and he gave some additional information regarding the Lisp engines produced at Symbolics. The Macintosh SBC was called the MacIvory. He gave some specifics about which of these devices which a computer collector might want, and this information will come in a later posting. Still, he said that the company is still in business, having been bought out by some individual but, that it is apparently nothing more than a maintenance operation. Still, when I get the telephone number of this person (he has an AOL account, as I understand), I will call him and see if he is aware of the availability of some MacIvory's and what one might cost. Chuck noted that the MacIvory worked only for nubus Mac's and that it had a tendency to crash MacOS. He said that the TI product was more resilient in hardware than MacIvory but, the condition was just the reverse for software executed on the respective machines. That is, the TI did not crash so often but, the applications were not so well developed or capable. William R. Buckley

Replacing 6550s

by ds_spenc＠alcor.concordia.ca

Hi all! Thanks to everyone who supplied information regarding the differences between the 6550 and 2114 (especially Ethan who supplied pinouts). I'm wondering if it would be possible to replace the RAM in an old PET with a modern SRAM by use of some kind of plug-in adapter. An example of what I'm thinking of is the SIMMfonie or AmiFast Zip-to-SIMM adapters for the Amiga 3000. Could something like this be built that would plug into the 16 22-pin sockets on the PET motherboard, and lead to a single modern SRAM? Possibly with the addition of a couple of clip-on leads to get two more address lines to the RAM adapter so that the PET could have 32K. My general preference is to keep things original, but functional is always better than non-functional and something like this adapter would be removable if I ever found the proper chips. The life of a chicklet-keyboard PET may depend on this. :) -- Doug Spence ds_spenc(a)alcor.concordia.ca http://alcor.concordia.ca/~ds_spenc/

HP Vectra networking (26 days OT)

by roblwill＠usaor.net

This is about 26 days off-topic. I have an old HP Vectra RS/25-c 386-25/1MB RAM, 100MB HD, 1.2 MB floppy. (BIOS dated 1989). I"m trying to get it set up as a home server, but I first need a few things: -Setup software. -Networking software compatible with the internal networking card (there"s a plug next to the keyboard connector that looks like it wants to be connected to some sort of network hub). -An old Vectra keyboard?

system info request

by allisonp＠world.std.com

< I'm buying an old 486 and want to try some of the FREE alternative OS' ( < Microsoft stuff thank you) that are available for it. Operating systems < as GEM, QNX, OS/2 and GEOS. Can anyone recommend any other that can be r < such as embedded or old operating systems? If you have at least 8meg of ram in that 486 try Linux, Freebsd, OpenBSD or NetBSD. These are all free (maybe a few dollars for the CDrom) and represent high performance unix operating systems of various flavors that are mostly similar if not the same. I'm not a unix fan but compared to MSwinders and the dos similars (other than OS/2 warp or concurrent cpm) it's a real screamer. Another one if your interested in OS internals is Minix, the disk set to install on a 486 is only a dozen floppies and it will fit with sources on a 40mb drive. It's unix but simpler, of the V6 flavor. it's simplicity makes it quite fast! Allison

new hamfest additions

by SUPRDAVE＠aol.com

good size hamfest in greensboro, nc and here is what i picked up. epson hx20 complete with plastic carrying case. where can i get the tiny cassette tapes for it and it also has a expansion unit added on the left. what does that do? no ac adaptor to test yet. the guy also had a commodore sx64, but too expensive. also picked up a ps2 model 60 that worked fine once i ran reconfig on it. an interesting find is a complete ti99/4a system still sealed in its box along with the expansion unit and optional floppy drive, all for $15. the 3 boxes were never opened until i did it. it's the beige model rebadged by CDC for schools here in raleigh. i also got ~50 disk based school software titles for it as well. all of it's worthless of course, but interesting to find something well over 10 years old and never saw the light of day until now. david

old(ish) computers for sale

by Marion.Bates＠Dartmouth.EDU

Hey all -- sorry if this is uninteresting -- I have no idea about the age/value/rarity of these machines, but the CS dept here is selling them, and if anyone's interested, email me privately. This is forwarded from the lab admin. -- MB ---------- * DecStation 500 - the old risc (not alpha) Dec, with keyboard, mouse, and video cables, but without monitor and scsi disk. Apparently these run FreeBSD, though I have never tried it. They don't run Linux. $100 each. * Sun IPC - one of the early sparc architecture machines, it is old enough that most people have never heard of it. I believe that it won't run the newest Sun OS. With a huge 19" or so color monitor, 16 meg memory, and hard drive. One only. $250 * Mac IIci - I have about ten of these puppies, no monitors, but probably a mouse and keyboard if you act fast. $35 * Sun computation center - a Sun-60 desktop server with scsi disk, a sun-120 vme-bus machine with non scsi tape controller, and a 9 track reel-to-reel tape drive. You must remove the (very heavy) tape drive from the rack that it is in. This was much faster than the Vax 11-780 that used to be the heavy Unix machine on campus, back in '89. $250 takes it all. Bring a truck. Small print: All sales are final. This equipment is sold "as is" with absolutely no warranty. I am not able to answer any questions about software installation or setup. You can try the equipment if you want to do all the lugging. The equipment must be removed from Sudikoff Lab within a month - if I find it around after that I will throw it away! There may be viable operating systems on the disks of any machines with disks, but I am not selling any rights to use the software or offering upgrades or replacements. (I believe that the Sun right to use goes with the equipment.) Prices are negotiable. In cases where a disk is included I will sell the item for substantially less without the disk or disk enclosure. If you have to ask how, it is probably not for you....

Keyboards

by cube＠msn.fullfeed.com

I built one, once upon a time, out of a Univac keypunch keyboard and some TTL logic. Worked great. Used it on my Altair for years Really nice LOUD CLICKS. Loved it. I suspect this would be tough to do with a modern PC keyboard, but if you look at really old stuff (like at a state/university surplus sale or some such) you might find something.

If this went directly to Russ he would have gotten it, but on the list it makes it seem like he actually overpriced it. Sorry.

Oh, and kiddies, cover your eyes: "Gates be damned... all of my CoCos now have Extended Basic...

Cipher 9-tracks

by rexstout＠uswest.net

Got two of them. One of them is an IBM 4968, not terribly difficult to figure out. But the other one has me stumped. Model number 0920940-98-125OU, I'm not sure if that means it's a 920 or a 940... Part number 155000-103, Option B. Found some spare parts lists at www.4cipher.com that seem to match, but they don't have much info. And I thought I would come here to the list before bothering their sales department(only email address I could find), as they rarely know much of anything that isn't in production... -------------------------------------------------------------- | http://members.tripod.com/~jrollins/index.html - Computers | | http://www.geocities.com/Area51/Lair/1681/ - Star Trek | | orham(a)qth.net list admin KD7BCY | | ham-mac(a)qth.net Portland, OR | --------------------------------------------------------------

RL01/02 and RK06/07 terminators

by cfandt＠netsync.net

Question: Are the terminators for the RL and RK drives the same? No part number on outside of any of the three terminators I have on hand. One was found on an RK07 another on an RL01. All three have a Cermet network with 40 leads connecting to each connector pin. The P/N on each Cermet network is 13-13242. Just trying to make sure as I'm trying to get an RK07 running w/11/34A an RL02 w/11/24 and neither disk is accessed by its processor. Yes, the cables are sorted out as to whether they're an RK or an RL type. Thanks for the info.

I seem to remember reading about this - perhaps in the "Straight Dope". A quick www.dejanews.com search led me to a Toyota FAQ that confirmed what I remembered. Newer "low rolling resistance" tires don't contain as much carbon black as they once did, which makes them more of an insulator, which means as they turn they're picking up a charge relative to ground. Other articles I saw mentioned this was a problem with AM radio reception, causing sparks as the charge dissipated as you drove, and for toll booth operators you'd touch during a drive.

System/23???

by rhblake＠bigfoot.com

Ok here's one for all those of you familiar with the older IBM iron. I have just fallen into a unit that looks much like a TRS-80 model 3 or 4 (all in one in other words) that has two 8" floppies, a CRT, built on keyboard. It says it's a model 5322 and the face says it's a System/23 unit. This is before my time I'm sure (my time in messing with pooters). It has a 9 pin d-sub with a jumper loop on back and then further up the back it has another, but open, 9 pin female d-sub. Token ring maybe, or where a twinax adapter might go? Whatever info you have would be great, and if anyone has an interest in this heavy bugger let me know. I haven't even powered it up yet but it does have an original IBM floppy in it, not even sure if it's a boot disk or not. I have a weird feeling it's a wordprocessing terminal. It even has a keyboard overlay that sits above the keys. Russ Blakeman Harned, KY

Old 386 and 486 pc's

by SUPRDAVE＠aol.com

harrumph; typical clueless non-computer type that thinks any old computer is worth plenty. there's a guy at an established flea market that tries to get the same price out of old machines. i bought a northgate 386/20 from a guy at work and even got the great northgate keyboard too for only $20! heh, you oughta go back to the guy and ask him if he'd be willing to buy comparable 386 and 486 models for half his asking price. i could find some pretty cheap machines and make profit off him!

Someone with an RL02 needed.

by DSEAGRAV＠toad.xkl.com

I started diggin thru the tapes I got from knox, maybe one of them was a backup of RSTS. Found one. The gotcha - It'll only extract to an RL02. So, anyone got a PDP-11 with an RL02 and a TS tape? I need someone to extract the tape for me, and shove it on a disk image like the ones E11 takes. I should be able to unscrew myself from there. -------

Any Zilog 8000 collectors out there.

by Innfogra＠aol.com

While rummaging through the back corner of the whse I stumbled across a bare Zilog 8000 card cage with a full complement of cards. Circa 1983 Mfg. Every slot full. This would be a great backup card set or a way to get a non-working Zilog up and running. I also have an extra memory card beyond that. I also discovered a Daisy Logician Card Multibus cage and cards also. I doubt anyone is collecting these though. If interested please reply to whoagiii(a)aol.com directly. Thanks for the list, Paxton

If the markings are for a Dallas 12887(a) then the NVRAM is integrated with the clock chip & battery. To my knowledge, the closest person to being world-famous for changing a Dallas battery would be Dr. Marty Goodman, of CoCo fame. IIRC, he's a member of a mailing list gatewayed to the newsgroup bit.listserv.coco, so if you send a message there, he should eventually get it (along with everyone else on the gatewayed list, so pose it as a CoCo-ish question... tho CoCoists (IMHO) aren't quite as rabid as some other platform gurus...) >> You're supposed to replace the chip when the battery fails (after about >> 10 years). I have heard of people carefully slicing the top off the >> package and replacing the lithium cell inside, but I've not had to do >> this myself - yet. If it is a Dallas 12887 (without the "A" suffix), I can tell you this: beware of the Dallas 12887. The 12887 has one shortcoming: the NVRAM *cannot* be reset via external means, which means if whatever machine has fouled the NVRAM so badly it can't boot, it'll *never* boot again without replacing the chip itself. Some PC's used this chip, and said machines are a thorn-in-the-side when their NVRAM settings go haywire. IIRC, the Dallas 12887A is pin compatible, and *does* have an NVRAM reset pin... I also know that you can get all the pin info & other stuff from Dallas's website, which is slightly confusing at: http://www.dalsemi.com/ Watch out, tho: All their datasheets are in PDF format, so you'll want to grab Adobe's Acrobat reader to view the sheets with. The page with all of their PDF's for their chips is: http://www.dalsemi.com/DocControl/PDFs/pdfindex.html Hope this helps, Roger "Merch" Merchberger

Call for final Elf99 design input

Any other suggestions? The only thing I see missing is the expansion bus connector. (Did I miss that part?) There are hundreds of things that would be nice to have, but it's important that the design be finished and the boards made. Leave the bells and whistles to the end users. If you create an Elf that can address about 2K, has a small prototype area, and has a good expansion bus, then all things are possible.

Call for final Elf99 design input

by allisonp＠world.std.com

The key to the elf design was minimalism and low cost. Substituting a latch and LEDs for a binary display instead of the til311 is cheaper and more buildable. using modern cmos and rams help. The basic elf was far to minimal and frequently expanded to get desired functions. The basic design did not easily permit that as it didn't decode memory or IO addresses. The RCA VIP or the 18S020 Evaluation board allowed far more flexibility with relatively little more logic. Thei cost was they had some rom. The 18S020 board was 4k ram (1822s), two 1852 as parallel io ports, UT4 monitor rom (512bytes) and another 32bytes for monitor storage. It used Q and EF3 for TTY/RS232 and the bus was available with numerous decodes at the edge connector. It also had LEDs for data, address and processor status lines (binary). This is a reproducable design. UT4 fits in 512byts of a 2716, the rest of the ram can be done with byte wide parts. The 1852s can be kept and the rest were common 40xx series. With 4k of ram and UT4 (or similar) programs like PILOT, TinyBasic, or some of the other neat software with a terminal. A much simplifed machine using 1802, 2 1852, 2 4028, 2 4042, 1 62256, 1 2716 and 1 6116, some glue logic for reset, run, runp and the same serial scheme as 18S020 would give 32k of contigious ram, 2k-32byts in the >8000h area and the remaining 1.5k in the 2716 could hold any number of things along with the .5k ut4 monitor. This would be a very useful system that could accomodate expansion for IO (more ram??????). Allison

OK, I'm stuck. I need a RSTS tape.

by DSEAGRAV＠toad.xkl.com

I think INIT's corrupt. Specifically, SAVRES. I'm trying to shove the RA81 on a tape. I say SAVRES, from DU0: to MS0:, and it says INITIALIZING FIRST SAVE SET or something along those lines, shoves the tape around for about 45 minutes, then says STARTING SAVE FROM DU0: TO MS0: AT XX:XX AM (or something similar) and hangs there (not doing anything) for a few minutes, after which it traps through 10. (Illegal Instruction, I think...) Does anyone have a RSTS 8.0-07 tape I can suck just INIT off of? Is there any way to do this under timesharing? I don't have BACKUP... Seems someone's removed that too. -------

Audio Cassette formats; Copy protection?

by foxnhare＠goldrush.com

Anyone else? The popular (quick) way was to put an RTS in the second cassette buffer with a SYS in the code pointing to it. (on the PET) and save the program from that to the end using the MLM. Then if someone SAVEs it regular and tries it it just crashes. The most ingenious PET protection was to put a bit of code in the FIRST cassette buffer, so you had to save it from the second cassette port using the MLM to make a runnable copy. Second would be to plug a bit of code into the chargot (I think) routine in low memory which will trick the computer in running the program once loaded (this could easily be bypassed on the PET, but on the 64, it was pretty fool-proof. On the 64 if you can get to the vectors before the user can try SAVing, you change the jump address for SAVE (locations 818,819) to your own location. > > On the 64, you could type > > > > 10 remL > > > > (rem, then a shifted-L) > > > > and LIST will stop up with a ?SYNTAX ERROR when it hits that line. > Rather > > easy to defeat but annoying as heck. :-) > > Same on Basic 2 PETS.

So was this to twart those modifying the code, or tracing it?... Oh... add a REM shift-l after it, once the 'fix' it it still doesn't work. Only problem with the delete character is if you list to a printer they will all show up. > > Philip. That same PET program had an ingenious listing protection too, the first two lines were only listable and they were effectively masked by rems with a bunch of delete characters. What the programmer did was break the line links after the second line so the computer thought it was a two line program. But when run the two lines restored the link via POKEs, once it was running past that point, it restored the line break. If you are curious to see this marvel in action it is on-line; check out my Flash Attack page and download either of the PET versions, this was written by Tim Stryker years before he founded Galacticomm.

Hi! Anyone have a hard drive controller for a Tandy 1400HD laptop that they'd want to sell? The one in mind recently died, and when I turn it on, all I get is a blue screen. I disconnect the HD, it starts to boot (BIOS number comes up), then stops, and starts emitting a fish-like smell. I pull the controller entirely, and it works fine (with no fish smell).

We didn't try recording with Dolby and playing back without. I'd be very surprised if that worked (did you mean it that way round). I can't remember if we recorded with and played back with - I imagine that would work - but we definitely couldn't get it to work recording without and playing back with, although this actually works quite well for music. > I would be suprised if you couldn't make a CD that could be loaded. I > can't try it because I have no way of writing to a CD. I never meant to imply that you couldn't make a CD that could be loaded. What I meant was you probably have to be more sophisticated than old cassette -> digitised audio -> audio CD. I'd recommend old cassette -> signal restoration -> digital signal (0s and 1s sampled at some highish speed) -> possibly prefilter to pre-emptively undo the CD player's output filter -> digitised audio -> audio CD. For PET (and family) tapes a C2N would probably make a good cassette machine for playing it initially, since it does some of the signal restoration itself. Philip.

Actually, quite a lot of them do have info (if sometimes well hidden) but some -- Intel comes to mind -- aren't very good about keeping old stuff, and Toshiba are pretty hopeless. I needed some other info from the same data book that those EPROMs are in, a few years ago, and ended up phoning Toshiba to get it. Turns out they stopped making EPROMs about a year before, and no longer had the data sheets themselves! Luckily one particularly helpful customer support person found me what appeared to be the last copy of the Data Book. I was very glad I checked, because there are two common pinouts for EPROMs in that sort of size range. Most manufacturers distinguish them by either using the last four digits in the form "1024" or "1000", or they use "1001" versus "1000". Except Toshiba -- where others used "1000" they used "1001" and vice-versa. -- Pete Peter Turnbull Dept. of Computer Science University of York

Dec RC25 offered

by Innfogra＠aol.com

3M silentwriter model 1483?

by cdrmool＠interlog.com

Anyone know the story behind this? Its a small keyboard connected to a small thermal paper printer. It has an old 70's style phone jack (at least the kind we used in Ontario Canada) coming out the back of the printer. My father who found it says he thinks its one of the early devices used by the deaf. I think it was probably just a simple terminal. Whose right? who gets to carve the christmas turkey this year? colan

VAX collectors attention

by CLASSICCMP＠trailing-edge.com

>IIRC, it's actaully a PDP-11 and the OS is a munged version of RT-11. The filesystem it uses on TU58's is the same as RT-11's filesystem. That doesn't mean it's running RT-11 :-). A VAX-11/780 has an LSI-11 as the console processor, it uses the RT-11 filesystem on the boot floppies, and that doesn't mean it's running RT-11 :-). On the other hand, VAX 8600 series CPU's use a PRO 380 console running an operating system that *is* derived from RT-11. (The VENUS conditionals still abound in the RT-11 sources, even though AFAIK a build hasn't been done in over a decade.) -- Tim Shoppa Email: shoppa(a)trailing-edge.com Trailing Edge Technology WWW: http://www.trailing-edge.com/ 7328 Bradley Blvd Voice: 301-767-5917 Bethesda, MD, USA 20817 Fax: 301-767-5927

I think I remember the 3M flavor having the latter name. I played with one of them back in 1983 or 1984. That one had a keyboard connected to a thermal printer by some sort of cord (they were separate boxes), and I think an RJ11 phone jack for a POTS line. As I recall it was an ASCII terminal plus modem with a memory buffer that could be used for offline composition, and it came to us recommended as a tool for composing and sending Telexes via Western Union's Easylink service. (We sent it back and made an HP150 do the job.) I don't remember if it could be made to do other codes than ASCII. More recently (early 1990s), I've seen one with a little CRT (again in a separate box) used as a Telex terminal, but didn't inquire to find out how it was connected or what was on the other end of the connection. -Frank McConnell

Call for final Elf99 design input

by dcoward＠pressstart.com

First I just want to say that I'm still looking for 'copies' of two RCA publications: MPM-232 Operator Manual for the RCA COSMAC DOS Development System (CDS III) CDP18S007 MPM-233 Hardware Reference Manual for the RCA COSMAC DOS Development System (CDS III) CDP18S007 If you have one or both or know where to order these manuals, please let me know. O.K. I said: >I think there is a source code listing in Paul Moews book on >Elf interpreters. I dug my copy out and yes there is source listings. Paul took RCA's CHIP-8 interpreter and modified it for the ELF. In this book ("Programs for the COSMAC ELF: Interpreters"), he starts with a subset interpreter that has 10 CHIP-8 instructions and is intended to run on a 256 byte Basic ELF. Then he lists the full Elf CHIP-8 interpreter with all 30 instructions. This is intended for a 4K Super Elf with 1861 video, but it can run on a 1 1/4K Elf. "It is also possible to use CHIP-8 in the 1 1/4K ELF's described in the articles in Popular Electronics, but to do so is very tedious unless the switches are replaced with a latched decoded keyboard." He also demonstrates with listings, how to extend the CHIP-8 instruction set. I can send you a copy of this book, it's only 31 pages. I also have one of his other books called "Programs for the COSMAC ELF: Music and Games". ----------------------------------------------------------- Fun Fact of the Day Did you know that a windowing graphical user interface was available for S-100 bus in 1979?

All Dolby B seems to do, is increase the level of high frequencies when the recording is made. Then when played back, the Dolby NR reduced the level of high frequencies back to what it should be (hence also reducing the background hiss). So recording with Dolby off and playing back wilth Dolby on will serve to reduce the level of high frequencies; not what you want with computer tapes. Recording with Dolby on and playing back with Dolby off should probably work; high frequencies will be louder than normal. >For PET (and family) tapes a C2N would probably make a good cassette >machine for playing it initially, since it does some of the signal >restoration itself. Better might be to use a high-end tape deck (maybe a three-head unit) since the transport should give less wow & flutter. -- Mark
