FWD: RSTS/E Manuals

by kyrrin＠wizards.NOSPAM.net

Fellow in SoCal's trying to get rid of some worthwhile-looking books. Anyone interested? -=-=- <snip> -=-=- I was surprised to receive no response whatsoever to my original post. When I started collecting PDPs, I grabbed all the documentation I could get my hands on. Maybe nobody runs RSTS any more. Maybe V9.0 manuals are too old. In any case, the manuals I described in my original post (below) go in the trash if not spoken for by Friday July 25. ---------- Greetings. Unfortunately, my interest in PDP-11s exceeds my available storage. I picked up a partial set of RSTS/E manuals a while back, but find I now need the space they occupy. These are the standard orange DEC binders, and most of the contents are still in shrink wrap. The partial set is as follows: ---------- System Management (Volume 2) System Manager's Guide System Usage (Volume 3) System User's Guide Guide to Writing Command Procedures Utilities (Volume 4) Utilities Reference Manual Introduction to the EDT Editor SORT/MERGE User's Guide RUNOFF User's Guide Utilities (Volume 4A) EDT Editor Manual Utilities (Volume 4B) Task Builder Reference Manual Programmer's Utilities Manual RT11 Utilities Manual TECO User's Guide BASIC-PLUS (Volume 5) BASIC-PLUS Language Manual System Programming (Volume 6) Programming Manual MACRO Programming (Volume 7) System Directives Manual ODT Reference Manual MACRO Programming (Volume 7A) MACRO-11 Language Manual RMS-11 MACRO Programmer's Guide RMS (Volume 8) RMS-11: An Introduction RMS-11 User's Guide RMS-11 Utilities ---------- These manuals are located in Southern CA. Shipping would be pretty expensive, and I would prefer not to have to pack them (e.g. preference granted to those who could pick them up). I am not looking for much (if anything) in return for these; I really just want them gone and suspect someone might need them. If you want me to pack and ship them, though, I will probably want something to offset my time and trouble (and shipping, of course). I am always looking for Q-bus hardware, and right now specifically for S-box (BA213) cabinet kits for a KA650 and a VCB02.

Apple Lisa Owners??

by kaikal＠MICROSOFT.com

Welcome! Which Lisa model do you have? I have a Lisa 2/10 that is almost working. The hard drive install of Sun's version of MacWorks is apparently corrupt and it doesn't boot completely (or needs a boot floppy that I don't have). I'm loathe to fix the MacWorks install because I'd rather run the Lisa Office System. Problem is, the Lisa Office System is serialized, and, once installed, it will only reinstall on the same Lisa. There are some outfits around that will sell copies of the uninstalled disks for $170, which is a bit steep. I have an acquaintance at a local computer recycler who has a set and is willing to let me borrow them, but I'll have to set up a PC with two 720K drives (which I don't have handy) and a Copy II Option Board (which I do have) to dupe them.

Minicomputer Storage Myths

by carl.friend＠stoneweb.com

In a few assorted threads I've seen under various names like "RSTS/E Manuals" and "Minis not 'Trendy'", several folks have put forward the argument that minicomputers are too large to collect easily. I have one word: "hogwash". For the most part, your typical minicomputer fits securely in a 19" wide rack. They're typically either around 5.5" or 11" high, or there- abouts, and they're usually 22-30" deep with some going a little deeper. They stack nicely for the most part as all the surfaces are at right angles to one another. They do weigh a certain amount, but usually do not top 100 pounds or so. Yes, collecting them does take creative space management. I noticed that one chap has installed his pdp11 under his bed; good call! I hadn't thought of that one... Another guy gripes about putting a mini in his Honda Civic for transport. My wife did just that when she came home with a DG Nova 1200 for me a few years back; it fit very comfortably in the trunk. I just got back from a trip to the US Midwest with two minis in two 6' bays in the back of my minivan (story coming on my website). Kevan has room in his loft for a half-dozen minis or so (looked at the pictures) once he gets things organised (sorry, Kevan) with space left over. I keep three minicomputers (half-height Novas) on a kitchen counter underneath our coffee-pot (I really should get a picture of that). I also have a small rack with three of my pdp11s in it living in the dining-room of our house - it makes a wonderful stand-up terminal stand. Smaller racks can be utilised as end-tables. The ultimate space-management tool in dealing with minis is the six-foot rack. In one of them you can mount an easy half-dozen machines; if you share peripherals, they can all be used too. Un- fortunately, my wife drew the line at that one, so I use the "scatter method" of space management. The bottom line is that _it's not as big a deal as it's made out to be_! It can be done, it should be done, and not enough people are doing it. The machines are disappearing - and that's a shame. ______________________________________________________________________ | | | | Carl Richard Friend (UNIX Sysadmin) | West Boylston | | Minicomputer Collector / Enthusiast | Massachusetts, USA | | mailto:carl.friend@stoneweb.com | | | http://www.ultranet.com/~engelbrt/carl/museum/ | ICBM: N42:21 W71:46 | |________________________________________________|_____________________|

HHCs (bad news)

by dastar＠crl.com

I have some unfortunate news to pass along to everyone interested in the Panasonic HHCs. The deal is now off. Due to a lack of communication within the company that had the units, they were all, in the words of Mike Westin who was the go-between in the deal, "shit-canned". The company simply threw them out because they did not know there was an offer tendered. On the positive side, there are still roughly 50-75 units still left within the company that are still being used by employees, and will be so for about the next two months. Mike is currently developing a new product for the company, at which time they will no longer use the remaining units, and they will then, hopefully, be sold to us. So for now, no HHCs. Its disappointing, mostly because the thought of all these nice systems being simply thrown out is a damn shame. However, we may yet be able to acquire the remaining units in a couple month's time. Stay tuned. Sorry all. Sam ------------------------------------------------------------------------------- Computer Historian, Programmer, Musician, Philosopher, Athlete, Writer, Jackass

Sometimes I'll get a machine because I know what it is, and because I remember it. The Tandy M4 I bought a couple of weeks ago fits in here - I grew up on a Tandy Model 1, and remember the M4 coming out. I wanted one then, but could never afford it. Now I can, and can run those programs from 80-micro.... But more often I get a machine because I have no idea what it is, but it looks interesting. The P850 (the machine that seriously started me collecting) fits in here. As do the PERQs - I thought it was a 68000 box when I got the first one, and was amazed to see a soft-microcoded CPU. Learning from such a machine is great fun...

It's not that hard. What started me off was getting a relatively simple minicomputer - I'd recomend either the PDP8/e or the PDP11/05 as a starter, and sitting down with the machine, the technical manual, and the printsets. I single-stepped the machine, and watched how it executed an instruction with a logic probe. I where the microcode went, what gates were enabled, etc, and related it to the diagrams in the manual. After a couple of days I could understand most of the instructions.... >Got any pointers to where we could learn more? Yep... CPU Technical manuals from the late 1960's - early 1970's.

If you want to see something really scary in that regard, open up an HP 9000 series 5xx and look at the CPU boards. Those *really* look like gold, closer to solid than plated. I was looking (mostly for the memory) a bit more intensely a couple of years ago, and found that 2100 parts were also in demand to keep running systems running. > I must agree with you here.

Personally, I am starting to shift into the IBM > world, as it really has been ignored by historians (other than Paul > Pierce (who must be laughing at us weenies and our problems storing minis > and micros) and IBM itself). Yep. The mini world was kind of wide there for a while. I expect some of those machines really are gone forever. Has anyone here ever heard of a company called Digital Systems Corporation, based somewhere in (I think) the Maryland suburbs of Washington DC in the late 1970s, maybe into the 1980s? I worked on something of theirs once, called a Galaxy/5. Never heard of it or them since. Come to think of it, there could be good reasons for that, and it could be a good thing. Nah...we've got to keep the failures around too -- learning from mistakes is so much better when they're someone else's mistakes. -Frank McConnell

Oddly enough, Diana and I have been together now for the better part of a decade, and while she occasionally grumbles about my hobby, she supports it because she knows that it's important (not just to me, but for a larger cause as well). I believe the use of the term "crap" comes from fundamental misunderstandings of our common computing history.

It all depends upon how seriously we take our hobby, doesn't it. (That was merely an observation, _not_ an editorial comment!) For what it's worth, an IMSAI is just about twice the size of a pdp11/23. And less than a quarter of the CPU power. ______________________________________________________________________ | | | | Carl Richard Friend (UNIX Sysadmin) | West Boylston | | Minicomputer Collector / Enthusiast | Massachusetts, USA | | mailto:carl.friend@stoneweb.com | | | http://www.ultranet.com/~engelbrt/carl/museum | ICBM: N42:22 W71:47 | |________________________________________________|_____________________|

Lonesome Minicomputer Owner

by impeesa＠arrakis.es

Hello all, I own a Honeywell 716 Minicomputer, in running order. It?s a general purpose 16-bit machine, with 128 KB of ferrite core memory, a cassette tape device, a front panel as main console, and an ASR-33 Teletype as operator's console. There were other peripherals, such as line printers, fixed disks, card reader-puncher, high-speed paper tape reader, 9" tape decks... but I only own the basic system. The system was designed (aprox.) in June 1972. Has anybody ever heard about such machine? I?ve spent some time looking through the net, and looks like I?m the only one I own that system. Perhaps Honeywell didn?t made lots of them, like DEC did with PDP's. I?ve read somewhere (don?t know if it?s true) that first nodes in Arpanet were Honeywell DDP 516. I think my system is the next model (Honeywell DDP 716). In fact, mine can execute H-516's instructions set. I also heard U.S.Navy used these systems for shot calculations. If anybody has any information about the Honeywell DDP 516 or 716 machines, please email me. I?m looking for somebody who worked with those systems or even better, somebody who owns one of them. Thanks in advance. -- Sergio Izquierdo Garc?a ** Computer collector ** mailto: impeesa at arrakis dot es

DG Hardware Available

by carl.friend＠stoneweb.com

In mail ID number 9707221139.AA13838(a)alph02.triumf.ca, Mr. Tim Shoppa laments: > What I'm amazed at is that I've got several thousands pounds of > Data General Eclipse S/130's up here in B.C. - machines with full > toggle-and-light front panels - and I'm unable to give them away. This is a crying shame. For plain beauty, the S/130 rivals, and to some, outranks even the much-vaunted IMSAI. For raw speed in a minicomputer the 16-bit line from DG was virtually without peer. Yes, some late -11s surpassed the raw power of the Nova instruction set, but it was years behind DG. We'd better save these machines while we can; Data General was, at its zenith only about 20% of the size of DEC, and its install- base was similar in scope. These machines are _not_ common, remain useable today, and are a joy to look at and run. Don't let the opportunity pass. > Are classic minis, including PDP-11's and DG mini's only items for > the junk heap? I, for one, certainly hope not. Part of the misconception about minicomputers is that they take up huge amounts of space. Yes, individual examples are larger than the average microcomputer; however, minicomputers stack nicely, can be stored very compactly in rack-mounts, and being squared off, can occupy corners very well. They're not as space-intensive as one might think. They're usually faster than most micros, too. While minis don't, right now, get the blast of attention that machines like the IMSAIs do (why is that machine so popular? War Games, maybe?), they are a valuable link to computing's history and they're disappearing from existance very quickly. Without Mr. Shoppa's efforts, better than a dozen of these wonderful systems would have been shipped to the scrappers without a second thought. And that would be too bad. ______________________________________________________________________ | | | | Carl Richard Friend (UNIX Sysadmin) | West Boylston | | Minicomputer Collector / Enthusiast | Massachusetts, USA | | mailto:carl.friend@stoneweb.com | | | http://www.ultranet.com/~engelbrt/carl/museum/ | ICBM: N42:21 W71:46 | |________________________________________________|_____________________|

Tim Shoppa <shoppa(a)alph02.triumf.ca> writes: > Are classic minis, including PDP-11's and DG mini's only items for the > junk heap? No, but speaking for myself I am short on space at the moment (and don't see it getting better for a while), lacking organization (working on that one), short on time (which constrains both of the above), and short of space between my ears too (too doggone many learning experiences this last year or so and a medium-sized list of some I have yet to get to). This Sunday I told someone "you know, I sometimes think I should stop collecting and get to work with the stuff I have." Which is enough to fill one 10'x10' (figure 3mx3m) storage closet to where it's not too difficult to get to stuff and make a pretty good showing of boxed manuals and magnetic media in another. Certainly most of it needs some sort of work. And there are some minis in there amongst the micros: An HP 2100A CPU. Unfortunately it is the CPU only. No I/O, no memory, no peripherals to speak of. Did get the CPU manuals with it, though, and they have made interesting reading and probably will one day again. I am not actively seeking the other bits right at the moment but am keeping my eyes open. Two HP 3000/37 CPUs, and enough disk drives and other bits to make one of 'em work. Well, they're a little bit small for minis, at least if you consider just the CPU box. An HP Micro 3000GX, currently taking up space in my workroom, with a 7970E 1600BPI tape drive that gives the resident manager hives -- it's big and metal therefore it must be heavy, right? (I live in the apartment above her.) Can I call this a mini? It runs the same code that used to run on bigger 3000s, but it calls itself a "Micro" (and fits entirely in a little tower case that with packing material and box weighs 78 pounds -- what's that, 35kg?). Is it part of the colllection? Hard to say, I used to do real work on it, but I wouldn't part with it.... An HP 9000/520, but there we are straying away from minis into early 1980s supermicro/workstation sorts of things. Various manuals for the above, as well as other systems in the 3000 and 21xx families. Also manuals and print sets for a Nuclear Data ND812 mini. A few odd parts: HP 3000/III front door with panel (found this on a 19" rack at Foothill swap meet -- the guts were gone and I really don't need another empty 19" rack then or now); two HP 3000/CX front doors, goldenrod; probably other stuff that slips my mind right now. You may have noticed a preponderance of HP hardware in the above list. That is because it is what I know something about (have been doing stuff with 3000s for close to 20 years now, have dialed up 2000 time-shared BASIC systems way back when and know they are based on the 21xx-family CPUs (as are the early HP 1000 systems), and supported a product on the 9000/500 for a little while and came to appreciate its quirks). I don't know that much about DEC gear, and next to nothing about DG stuff -- never used it at all. Now *that* is sad: I am ignoring good stuff that I could probably learn something about, maybe even learn something useful from. But I am already having to come to terms with the fact that there is a lot of stuff to learn, probably more than I can fit into one lifetime. Or maybe I've just got a bad case of hardening of the brain? I don't know. But I wonder how many other folks out there think to collect things that they know stuff about, as opposed to stuff they don't know anything about? I have to admit, the former makes a narrower selection filter and the latter has gotten me into, um, unexpected learning experiences (yeah, that's it) more often than not. And for most people the "things they know stuff about" is more likely to be micros than minis. There's another point in there too: I've consciously ignored DEC stuff (or passed it on to other more interested folks) for the simple reason that there seemed to me to be a pretty active community working on preserving it already! But DG stuff is another matter, I just haven't really noticed much of it or much discussion of it. OK Tim, you've guilt-tripped me...a little bit. But I'm still wondering what I could do with and learn from some of this stuff. What would I need to make a workable system? I expect the definition of "workable" is variable amongst the readership, but I could amuse myself for a while looking at an instruction set reference card and having Real Iron on which to toggle in a lights hack would be a nice bonus. (Yes, I am apt to collect this sort of documentation in the absence of hardware too -- I am more a programmer than a hardware guy and I mostly understand computers in terms of how to wrangle code for them. And I really stand in awe of folks like you who can understand them in terms of hardware too -- another thing that is on my to-learn list.) Maybe it takes more to interest other folks, like the ability to hook up and use terminal and/or storage devices. Maybe even load some sort of operating system if that's what was customary on these things; I'd probably want to get there someday myself. (Of course that poses its own problem of where to get the operating software.) I don't know, like I said I really don't know anything about DG hardware as it was used in practice -- my background is in DP/MIS, datacomm, HP 3000s, and nowadays sticking IP-protocol-suite stuff into Windows device drivers. Got any pointers to where we could learn more? -Frank McConnell

Minicomputer Storage Myths

by ard＠siva.bris.ac.uk

From: MX%"classiccmp(a)u.washington.edu" 22-JUL-1997 17:47:54.16 To: MX%"classiccmp(a)u.washington.edu" CC: Subj: Minicomputer Storage Myths > In a few assorted threads I've seen under various names like "RSTS/E >Manuals" and "Minis not 'Trendy'", several folks have put forward the >argument that minicomputers are too large to collect easily. I have one >word: "hogwash". Absolutly! My parents (who have to put up with and store most of my little collection) don't like storing micros (in fact they moan for days when I bring home a TRS-80 or some such), but don't seem to mind the PDP11's/PDP8's etc anything like as much. The reason is simple. Micros are a pain to store. You can't easily stack them (the ones at the bottom get mangled, the pile slips over, etc). Monitors are worse. But minicomputers (generally) come in 19" boxes that either go into a 6' (or taller!) cabinet, or get stacked up in a pile in the corner. They are easy to store. The floor area taken up by a 6' rack is not much larger than the area taken by a micro, BTW... > I noticed that one chap has installed his pdp11 under his bed; good >call! I hadn't thought of that one... I've considered designing a bed with 3 6U or 9U rack bays under it. In the UK you can get beds with storage drawers under them, but one _designed_ for computers would be somewhat interesting... > Another guy gripes about putting a mini in his Honda Civic for >transport. My wife did just that when she came home with a DG Nova 1200 >for me a few years back; it fit very comfortably in the trunk. I just >got back from a trip to the US Midwest with two minis in two 6' bays >in the back of my minivan (story coming on my website). A large estate car (Station wagon?) will carry a _lot_ of minicomputer hardware. I've been in one which contained : A PDP8/e A PDP11/44 A Sun 3/260 (on its side, on top of the PDP's) A PPL graphics display + trackball A northstar Horizon (OK, a micro, but in a 19" rack) An Acorn System 4 (ditto) A _lot_ of spare boards, drives, heads, etc Service manuals, printsets, etc. No problem at all. > The ultimate space-management tool in dealing with minis is the >six-foot rack. In one of them you can mount an easy half-dozen >machines; if you share peripherals, they can all be used too. Un- >fortunately, my wife drew the line at that one, so I use the "scatter >method" of space management. Odd... My parents _like_ big rack cabinets - in fact they grab them for me to put my machines in. Maybe I'm just lucky. > The bottom line is that _it's not as big a deal as it's made out >to be_!

I realised (10 years ago) that nobody was preserving the recent history of computing, and it was going to be lost for ever. So I did something.

RL02 (was Questions about 'BOOT')

by allisonp＠world.std.com

< Yes...most PDP-11 gear is that funky purple color...The early VAXen <were blue, the later VAXen were brown. Magenta is that funky pinkish purple. None of the vaxen I know of are brown, coffee stained maybe. The Vaxen were light grey (almost white) and medium blue or light grey and dark gray(with a coco-ish cast). The PDP-11 were medium blue, light gray(officially it was grey #68) and magenta at various times and combinations. PDP10s were litght blue and the system 20s were poppy orange. Most systems DEC made were by the early 80s gray 68 with some darker gray. There would be one stnadrad light grey (sorta eggshell) and about five darker greys like the TK50 carts, insets for micro11, pro350 and the insets for the BA11 pannel. Allison

Minicomputer Storage Myths

>Ok, they are a very convenient shape compared with Superbrains, Tandy >Model 4s and PETs. I only have a couple of PETs and they are a real >pain. What do other collectors do with these machines? Put them on top of piles of minicomputers :-). Seriously, I _have_ used chipboard/shelf brackets to make 'tunnels' that fit over the crazier shaped machines (PETs, etc), so that I can stack other things on top. If you do this, and decide to run the machines that inside the tunnels, then please add fans or at least make sure air can get into the cooling vents. >On the down side for storage space the manuals for minicomputers are >normally far more extensive than the typical 1/2" thick A4/A5 manual you >get with a micro. Indeed. I have a large pile of DEC printsets + A4 binders of user guides, etc. Mind you, the 8 IBM Techref manuals (PC, XT, AT vol1, AT vol2, O&A vol 1, O&A vol 2, Scientific O&A, PC-jr) take up quite a bit of space as well... >-- >Kevan -tony

PET FAQ

by Philip.Belben＠powertech.co.uk

I have some comments on the PET FAQ, but I've lost Larry Anderson's e-mail address. Accordingly I am posting it here, with apologies to all who don't wish to read it. > WHAT MODELS OF THE PET ARE THERE? > > The PET line was Commodore's first computer line after purchasing MOS > Technologies the primary design of the computer (as well as its > microprocessor, the 6502) was by Chuck Peddle. The line was labeled in > series' the first series, the 2001 series, the european 3000 series, and the > modern 4000 and 8000 series, and the final single unit 9000 series which is > the SuperPET. What about the 8200 Series? I am not sure of the differences between this, the 8000 series and the 500/700 (B/P) series - see my post earlier this week. I have also heard that the 8200 series runs BASIC 4.5, but mine runs 4.0. [...] > Large Keyboard PETs (no more internal datasette drive): > PET 2001 xN (x=8,16,or 32 depending on amount or RAM it was shipped with) > - Full-size key keyboard w/PET graphic symbols imprinted on keys I dispute this. The 2001 xN, of which we had several at school, had the new ROMs, the new motherboard (using 2332 ROM chips) but the small keyboard and the built in C2N. This was the essential difference between the N and B machines. > - Upgrade ROMs > - Many steel cased, some w/molded plastic tops. > - many with clearer green on black displays I thought all the N and B machines had green screens - we even had one straight 2001 (old ROM) with a green screen. > - Later versions had 4.0 ROMs installed Was this not only available as an upgrade? > PET 2001 xB (labeled as CBM, Commodore Business Machine) > - Full size xx key keyboard (no graphics symbols printed on keys) > - Upgrade ROMs (powers up in upper/lower case mode) > - Later versions had 4.0 ROMs installed > - Many w/molded plastic tops some steel cased. Our green-screened old-ROM machine was labelled CBM, but was again a small keyboard/internal tape machine. Otherwise I remember little about the B machines > PET/CBM 40xx Series (PET= N keyboard/ROM, CBM= B keyboard/ROM, xx= RAM) I wasn't aware of a small keyboard 4000 series. Interesting. > - 4.0 ROMs > - molded plastic top > 12" displays - updated video controller (prone to the 'killer poke') > - internal piezo speaker, audible startup, and right margin sound. > - 4.0 ROMs > PET/CBM 40xx (PET= N keyboard/ROM, CBM= B keyboard/ROM, xx= RAM) > - 40 x 25 display, upgradable to 80 columns > - lower case availabe by CHR$(14) which also changes line spacing. > 80 column series (can be set to 40 column mode via software.) Can it?!? I wasn't aware of this. You can restrict the area in which it prints on the screen to an arbitrary rectangle, but it doesn't behave like the 40-column machines in that the screen is still physically 80-column, it doesn't handle wrapped text, etc. The 8200 series could be set from 80 to 40 columns by unsoldering and moving two chips. I haven't done this to mine yet... [...] At this point you must mention the 8296 and 8296D! [...

It was discrete TTL, and simply read the screen memory, shoved it through the character ROM, and sent it to the monitor. It would not have affected printing speed even if you had speeded it up. The old PETs were slow because the SOFTWARE of the print character routine waited for the interval between screen scans before updating the screen memory. This reduced conflicts over the screen RAM which would have resulted in random pixels (snow) being illuminated on the screen. There was an input on one of the I/O chips which was hooked up to the video circuitry and told the routine when to access the video RAM. The famous poke was actually to another register of the I/O chip, and configured this input as an output. The older pets didn't mind (much!), and the print character routine saw the screen as always available, but on the later ones with the new video controller, this conflicted with another output and caused the video controller chip to do a wobbly (and could even have burnt out one or the other).

Preliminary PET FAQ

by kaikal＠MICROSOFT.com

A very complete Commodore ROM Geneology is in MICRO Issue 41, October '81. I have a copy in my PET Service Reference Guide, but it's 4 pages of tables and has handwritten additions that would be difficult to OCR. If you're a PET fan you might have this issue around anyway. By the way, the Service Reference Guide is a priceless piece; all schematics and test instructions, plus diagnostic cassettes and floppies. I have most of the Commodore "Techtopics" monthly bulletins also.

Help me out here, PDP-11

by thedm＠sunflower.com

This seems to be the favorite from what I can tell from the many discussions of Mini's. If I could get a hold of one of these, what parts do I need, what can I use it for and how much should I have to pay for it?

Minis not "trendy" enough

by 107765.1161＠compuserve.com

Message text written by INTERNET:classiccmp@u.washington.edu >> a mention that I have a front-panel IMSAI I get hundreds of emails from collectors and pseudo-collectors-wannabes who would bend overbackwards to pay me good money for it. Are the only machines that people collect trendy micros that have been featured in the "collectible" column of the _LA Times_ and the like? Are classic minis, including PDP-11's and DG mini's only items for the junk heap?<< >I can't speak for everyone, but for some of us the problem isn't that PDP-11's aren't "trendy" enough, the problem is space. I would love to< This is THE critical fact. Go into an antique store sometime, and look at the prices. You'll see some little knicknack for $300, and then you'll see a huge, 150-year old carved mahogany wardrobe closet for-- $260? The fact is EVERYONE has room for the small knicknacks, but few people have room for the wardrobe closets. Similarly, I can (and some day, probably will) decorate my office with cute little ZX-80s, Mattel Aquarius, CGP-115-type printer plotters and the like, scattered around for people to look at as curiousities (and ask about, if they're foolish enough to get me started); but, what would I do with a mini or an IBM 360 if I had one? Not that preserving some of the larger systems isn't a worthwhile effort, but I think most people would echo W.C. Fields comparing women to elephants: "I like to look at them, but I wouldn't want to own one."

HHC's?

Once we all get our units, we'll probably need a separate listserv to discuss them, swap programs and such.

Minicomputer Storage Myths

Minicomputer Storage Myths

Wanna here a crying shame!? I only collect micros, simply because I'm not at all familiar with Unix, Vax, or any flavor thereoff.

FWD: RSTS/E Manuals

by allisonp＠world.std.com

<dollars or drive hundreds (thousands) of miles in a rented truck (unless <you can fit a PDP-11 in the trunk of a Honda Civic) to pick stuff up. I've loaded an 11/23 with rx02 drives sans rack into one easily. A DG mini in one of the smaller boxes would fit. Keep in mind most of the minis the basic CPU box is rack width (nom 19"wide x 30"deep) and usually under 11" tall. Most 11/23s are in ba11N or S boxes that are 5-1/2" tall. An RL02 at 70pounds is rack width/depth and under 11" tall. The cak however can be bigger. I could easily fit a 11/23 or ther Q-bus pdp-11/rlo2/rx02 in any midsize trunk they arent that big. Also some of the short racks (30", 40", 50") fit in rooms easily. They are more than large enough to contain a PDP-11 or nova or several depending o disks and CPU boxes. I'd jump on a Front pannel nova but I can't swing the shipping unless I can keep it under 20$. Even thoug DG is only a few miles from here I've never played with their hardware. Allison

Odyssey2, Commodore Calc., 8" disks....

by coslor＠pscosf.peru.edu

Howdy: I picked up a few things today, and was wondering if anyone might have some feedback on this snag... including some more information on some of the items. To start with, I paid a total of $44 for the following. Feel free to let me know if I got a good deal... or not. 1) Odyssey 2 game system from Magnavox (Phillips). This comes with the original box, power supply, joysticks, TV converter box, etc. Also in this package is the THE VOICE expansion unit that allows voice output from the cartridge software. The unit itself is in _perfect_ condition! Thirteen game carts also came with this unit: Alien Invaders-Plus!, Computer Golf!, Attack of the Timelord!, Invaders From Hyperspace!, Speedwar, Spin-Out, Crypto-logic (the last three on one cart), Killer Bees!, KC'sKrazy Chase!, Sid the Spellbinder!, Type & Tell!, Football!, Nimble Numbers Ned, Bowling, Basketball (the last two on same cart), UFO!, and KC Munchkin!. Along with these carts are all the original boxes, in great shape, and the original manuals and countless other inserts! Does anyone know what the 'going' rate for a package like this might be these days? Also, does anyone have any inside info. on why ALL their titles end with an ' ! '?? 2) Commodore Solid State Electronic Calculator Model # 887D seriel #099632. I am seeking more information on this one. It's just a small digital (old style, lights actually are lit for numbers, etc.) calculator. This came with original manual, inserts, power supply, and box. I wasn't able to find a manufactured date, but on one of the instruction addition inserts, it is dated 10-1-1975. Please let me know if you might have more info. on this one. Also, let me know if there are any die-hard Commodore collectors that might be interested in purchasing this from me. 3) I found 60, six boxes of 10, 8" diskettes. These boxes are the heavy, plastic boxes that the top is spring-loaded to pop off. The disks are in mint condition and are unlabled. However, some of the boxes are labeled such things as 'daily backups', C, D, E, etc., and seems to be some accounting or other business disks. Can someone help me out and give some info on what types of machines used these? I know the Radio Shack TRS-80 Model 2,12, & 16 used these 8" disks but what others did? Is anyone interested in buying these up from me? I don't have a heck of a lot of use for them. Well, that's about all. Feel free to contribute any of the requested info., and anything else you'd like. Do you think I did ok financially on this deal? Also, if you're interested in getting 2 & 3 from above please let me know.... I will entertain ANY offers. Finally, I am also looking for any Atari 400 cassettes or cartridges. I don't have a disk drive, but am looking for one. Let me know what you have and how much you'd let 'er go fo, and we'll work something out. Also, looking for old TRS-80 software on disk and cassette, or CoCo cartridges, some keep that in mind as well. Thanks a ton for your time, CORD G. COSLOR //*=====================================================================++ || Cord G. Coslor P.O.

Preliminary PET FAQ

by foxnhare＠goldrush.com

I figured I'd shoot this by you guys as I am getting closer to putting it on my web site. I am sure I will get some good criticism from you all. If you have any additions/suggestions or additional questions to include, let me know. I also plan also to add in a couple texts on disk drive usage some PET memory maps (gee there are barely any PET maps on the net!) and if I don't find a link to one, an overview of Commodore PET BASIC (applies to 64 also). (view with a monospaced font for best results) THE COMMODORE PET COMPUTER FREQUENTLY ASKED QUESTIONS FILE - VERSION 1.0beta --------------------------------------------- BY LARRY ANDERSSON, COMMODORE COLLECTOR AND PET ENTHUSIAST --------------------------------------------- WHAT MODELS OF THE PET ARE THERE? The PET line was Commodore's first computer line after purchasing MOS Technologies the primary design of the computer (as well as its microprocessor, the 6502) was by Chuck Peddle.

The PET/CBM line had three major ROM revisions as well as a few minor ones, you cannot reliably determine the ROMs by looking at the outside of the PET (unless it has a large monitor). Fortunately there is an easy way to distinguish the three various versions by just turning on the computer. Depending on how your start-up message looks you can determine the ROM version: *** COMMODORE BASIC *** - Original ROMs sometimes referred to as 2.0* ROMs. (only found in the older calculator keyboard style PETs) Occupy $C000-$FFFF ### COMMODORE BASIC ### - Commonly known as the 'Upgrade ROMs' sometimes referred to as 2.0 or 3.0 ROMs depending on who you ask. Occupy $C000-$FFFF *** COMMODORE BASIC 4.0 *** - 4.0 ROMs The only ROMs that will work on large-screen PETs. Occupy $B000-$FFFF * Some people contend that BASIC version 1.0 never made it out of beta development and the PET line started with version 2.0 ROMs... Commodore on the other hand usually refers to the 'Upgrade ROMs' as V2, or 2.0. For the sake of sanity in this FAQ I will refer to them as original and upgrade ROMs, and as for an opinion I will go with the company's numbering (which leaves V 3.0 out of the picture). WHAT ARE THE DIFFERENCES AND/OR BUGS OF MY VERSION OF BASIC? Original ROMs Commodore had not yet implemented the IEEE-488 disk routines. Arrays are limited to 256 elements due to a bug in firmware. There is no machine language monitor nor could the PEEK command access locations above memory location 49152. The upper/lower case character set was inverted (SHIFT for lower case) (note: reading my sources there are ALOT of bugs, will take a while to compile them) Upgrade ROMs Many Original ROM bugs were squashed. BASIC commands and capabilities very much like the Commodore 64's. Now includes a tiny ML monitor and IEEE-488 disk operability. Easter Egg - enter WAIT 6502,x to see MICROSOFT!' displayed on the screen x number of times. 4.0 ROMs* Addition of direct Disk operation commands DLOAD, DSAVE, COPY, HEADER, etc. Ability to repeat cursor control characters by holding down keys. Reserved DOS error-channel variables: DS,DS$. Added screen 'window' formatting control characters. * The small screen-and large screen versions of these ROMs differ and some software developed for the small-screen 4.0 ROMS crash on the large screen units. This is due to the necessary changes made for the new video controller of the 12" display PETs. CAN I RUN VIC-20, 64, 128, PLUS/4, OR C-16 SOFTWARE ON MY PET? Maybe. Any program that is all BASIC that does not use hi-res graphics or sound and contains no POKES should work readily on a PET. Of course if it contains POKEs, sound commands, and Machine Language conversion will be nessasary. If it rely on more than one voice of sound, hi-res grpahics, programmable character sets or color, it may not be worth converting because those features aren't present on the PETs. NOTE: Many early VIC, 64, and Plus/4 BASIC games and programs were converted PET games. HOW DO I GET 64 (VIC, PLUS/4, ETC.) BASIC PROGRAMS ON MY PET? Unlike the later 8-bit Commodores,the PET always loads programs into the memory address they were saved at (i.e. no loading ,8 and ,8,1 as on the later machines), which means BASIC programs saved on VICs, 64s, 128s, etc, will not load in the right location on the PET to be seen by the BASIC interpreter. PET BASIC starts at location 1025 ($0401 in hex) and the later Commodore machines have different, higher starting locations. (see table x) There are a couple ways to get a BASIC program to load properly into memory, Disk Track/Sector Editors: My preferred method of conversion is using a disk track/sector editing utility to change the 'load address bytes' of the file directly on the disk. This is not an easy process to 'explain' and I hope to write it up at a later time. BASIC Line Relocation Method: Here is a way to get the BASIC editor to do it for you; of course you will need to have an upgrade ROM or later PET (which has a ML monitor) or load in a monitor for your original ROM PET first. It involves 'linking' the higher located BASIC program to a line starting in regular BASIC, when you delete that line, the editor will move your program to where it belongs in memory. 1. Enter NEW to erase any programs already in memory. 2. Enter: 0 REM 3. LOAD the program you want converted (i.e. LOAD"program name",1 for tape) 4. When loaded, enter the machine language monitor by entering SYS 1024 5. display the first part of the BASIC you first typed: M 0401 0408 6. Change the line-link to the memory location of the program to be moved; use cursor keys to move up and change the first two two-digit numbers to read: :0401 01 08 00 00 8F 00 00 00 ^^ ^^ (for a program from a 64, otherwise, see table x) 7. Press return to change the bytes then enter X to exit the monitor. 8. Type LIST, you should see the 0 REM followed by the program. 9. Enter 0 to delete line 0 which will move the BASIC to its proper place. 10. Save the program. TABLE X - Load Addresses for BASIC files: Saved under Start of BASIC Computer load load change Model/ addr. addr. bytes configuration dec. hex. to: ------------- ---- ----- ----- PET/CBM 1025 $0401 N/A VIC-20 unex. 4097 $1001 01 10 VIC-20 +3k 1025 $0401 N/A VIC-20 8k+ 4609 $1201 01 12 Commodore 64 2049 $0801 01 08 B-128 0003 $0003 * Plus/4-C16 4097 $1001 01 10 Plus/4-C16** 8193 $2001 01 20 C128 mode 7169 $1C01 01 1C C128 mode** 16384 $4001 01 40 * The BASIC RAM of the B128 is located in a separate bank of RAM memory, which starts at a VERY low address and will be difficilt to convert without a track/sector editor or saving it special on a B-128 itself. ** When hi-res GRAPHICS mode space has been allocated. WHAT KIND OF DRIVES CAN I USE? Tape Drives Tape Drives for the VIC, 64 and 128 work well on the PET. In fact you can hook up 2 tape drives on the PET (the second connector is inside the case, on the edge of the motherboard.) and can be accessed as device #2. Commodore Models: SANYO - First drives, power supply section cut out and modified for PET datasette cable/plug. C2N - Box look, black or cream colored case. 1530 - Rounded low-profile, counter & 'save' indicator light. Commodore IEEE-488 5.25" models 2020 - (first drive design, bugs may be present) 2040 - Updated ROMS, resembles a 1541 format & readbable on 1541/71s 4040 - Read/Write compatible with 1541/1571s. 2031 - Read/Write compatible with 1541/1571s. 8050 - Single Sided/Quad Density format, 512k per disk side. 8250 - Double Sided/Quad Density format, 1mb per disk SFD-1001 - Same as 8250, but single drive unit. Commodore IEEE-488 8" 8280 - 1 MB or 512k per Drive (little info on this one...) Commodore IEEE-488 Hard Disk Drives 9060 - Five Magabyte Hard Disk Unit 9090 - Seven Megabyte Hard Disk Unit 3rd party MSD-SD1 ** The MSD SD1&2 offer both IEEE-488 and MSD-SD2 ** VIC/64/128/+4 Serial bus interfaces. Modified 1541 PRINTERS? Commodore Model IEEE-488 Printers 4022 4023 8023 Some companies produced printers with IEEE-488 interface options (Epson was one) HOW CAN I GET PET PROGRAMS FROM DISK TO TAPE? You can just LOAD the program from tape and and SAVE them to disk one after another, of course, if you are using a VIC/64/128, etc. the loading address will get messed up. Fortunately there is a wonderful fily copy utility available for PET (4.0), VIC, and Commodore 64/128, called 'Unicopy'. Unicopy (written by the famous Commodore enthusiast, Jim Butterfield) allows you to copy from disk directly to tape. This of course preserves the loading address and makes things mauch easier. (also it performs multiple file copies instead of just one program at a time). HOW CAN I GET PET TAPE PROGRAMS TO DISK? Again you can do LOAD and SAVE as I mentioned or use a handy little utility I had discovered for the 64. This program will automatically LOAD each file off of tape and subsequently SAVE it to disk and continue until you stop it (or a disk error occurs when it attempts to save a file with the same name as one already on disk, disk full, or end of tape. HOW DO I HEAR/PLAY SOUND ON MY PET? Like many other microcomputers of the time the PET was not originally designed to produce sound. A few methods of sound generation have been developed but the most popular employs the use of parallel user port pin M which generates.... The latest 4000/8000 (large screen PET) motherboards have a built-in piezo speaker and also have a bell sound accessible with a print: chr$(7) Sound Interface Diagrams here... WHAT ARE THE BASIC COMMANDS FOR MY PET? For the most part the BASIC on the 64 is identical to the upgrade ROM PETs and it only varys by a few commands and features between original and 4.0 ROMs. On the other hand the 'memory map', the locations you POKE numbers into, vary quite a bit between ROM revisions. Memory Maps are available for all the versions... HOW DO I ACCESS THE PET's M/L MONITOR? The 'timy machine language monitor' (known as TIM to some) is available on all PETs but the original ROM version. TIM is invoked by executing a BRK instruction by SYSing any memory location containing a zero (0), most people enter SYS 1024, as it almost always contains a 0. WHAT ARE THE COMMANDS FOR THE M/L MONITOR? G - Execute M/L: G programaddress (i.e. G 033C) L - Load: L "filename",dev (i.e. L "PACMAN",08) S - Save: S "filename",dev,startaddress,endaddress (i.e. S "FLASH ATTACK",02,027A,2000) R - Display Processor Registers X - Exit Tiny Mon M - Memory Display: M startaddress endaddress (i.e. M 0400 04A0) : - Modify Memory (supplied in memory dumps using the M command) ; - Modify Processor Registers (supplied in the processor register, P command) CAN I GET A BETTER M/L MONITOR FOR MY PET? Yes, there are two that I know of that are readily avaiable. The most popular (and universal among the Commodore 8-bits) is Jim Butterfield's Supermon. There are versions available for all ROM revisions including original ROM PETS and offer a mini Assembler and Disassembler among other useful memory/ML commands. The other, similar to Supermon is called Extramon. There are other versions many of wich are commercial but I have little information on them. I HAVE A PROGRAM THAT CAN USE JOYSTICKS, WHERE CAN I GET/MAKE THEM? The PET was not initially designed for joysticks but a determined user had devised a dual-joystick interface employing the parallel port. This interface allows you to plug in standard Atari/Commodore compatible joysticks.... Interface Diagram Here HOW COME MY PET CAN'T READ A TAPE FROM MY PLUS/4 OR COMMODORE 16 OR VISA-VERSA? You are quite a collector, aren't you? When Commodore designed the Plus/4 and Commodore 16 they broke alot of standards they had previously established for their 8-bits (and fortunately went back to in the C128); besides the plug designs, they changed the sound-frequency of the signals used to record on tape. Though the the format is identical to the PET and the other 8-bits, the sound is only readable on the Plus/4 and Commodore 16. My sggestion would be to record the program on disk (1541) and then read it on a 4040 or 2031, or copy them from the 1541 to tape using a 64 or 128. WHAT IS THE 'KILLER POKE' AND SHOULD I WORRY ABOUT IT? This is THE POKE of computer lore, the command that WILL physically break a computer! Of course other commands and methods are known that can potentially cause damage (usually to disks, hard drives or other mechanical units), but this is the most notable mainly because it was a command somewhat commonly used and it affects solid-state circuitry. History of 'the killer poke' When the first PETs (small 9" screen) models came out, the display wasnt all that fast. It wasn't too long before someone learned they could impove the character printing speed via a poke to location 59458; which would set the video controller into a faster mode. It was a noticible improvement of speed on programs using PRINT often, it was kind of like a free upgrade. It was mentioned in a few publications and used in many programs that relied on printing to the screen. I had learned of the poke through Cursor Magazine, a monthly tape-based publication. They printed the command in one of the 'newsletter' flyers included with an issue which you could insert into their game "joust" to make it play faster. Later on, when Commodore released the larger display (14") PETs, they had improved display speed which made that POKE unnecessary. An unfortunate side effect was that the POKE to 59458 still caused the already faster controller to run even faster, in fact too-fast, which could result in damaging the PETs video curcuitry when left running. I discovered it by accident after our school received some large-screen 4016s. When active, the screen starts to warp after about the third line and the display stops around the fifth, the keyboard is also unresponsive. When a PET is in this mode, the only solution is to turn it off, quickly! Fortunately none of the school's PETs were damaged due to this POKE. Later Cursor Magazine published a 'fix' that would allow older PETs to use the poke and keep the large-screen units from frying. Unfortunately there are still many programs that do not have this fix. Prevention Make sure to check BASIC programs (especially games) when running them on a large-screen PET and be ready with the power switch when you first run it. I have usually found the 'killer poke' statement looking like this: POKE 59458,PEEK(59458)OR 32. The fix is to put an if-then conditional to determine if the poke is needed for the PET running the program, here is the code: IF PEEK(50000) THEN POKE 59458,PEEK(59458)OR 32 CAN I HOOK UP AN EXTERNAL MONITOR TO MY PET? With the help of the following circuit you can get a composite singnal from the user port... Insert Video Diagram here.... WHAT ARE THE PINOUTS SO I CAN BUILD AN IEEE-488 CABLE FOR MY PET TO MY DRIVE. WHERE CAN I GET SOFTWARE FOR MY PET? WHERE CAN I GET CONNECTORS THAT FIT THE USER/IEEE-488 PORTS? IS THERE A MODEM AVAILABLE FOR MY PET? I know of only one company that prosuced a modem and IEEE-488 interface, the company is TNW, and I think they also built the Commoodre 8010, an acoustic modem for the PET. I have some notes on using the device but have never actually seen one.

Apple Lisa Owners??

by bede0005＠gold.tc.umn.edu

Hi all: This is my first post to ClassicCMP. Let me just start by sayin it is great to see how much interest there is out there in different Classic Computers!! I recently aquired an Apple Lisa and was wondering if anyone out there also had a working model. So far, I have a copy of the Lisa Office System, the Lisa Tools, and MacWorks XL. What I'd like to find out is what other software for it was available and if anyone wants to get rid of it :) I know there is the workshop environment for programmin in Pascal, and I think a version of Unix and Basic were realeased. But what about Fortan? Also on the hardware side. Does anyone know of any cards that were made for the expansion bays. I know that a parallel card was available, and also something called a Priam Card. Anything else? Let's see one final question. What about printer support. Was it limited to the Imagewriter I, Apple DMP and the daisy wheel one (can't remember the name). Can one use the Imagewriter II? How about other printers? Well thanks to anyone with any info Rob

CoCo disks

by jeffh＠unix.aardvarkol.com

I found what looks to be a few intersting disks today, though at the moment I can't check to see what's on them or anything. They are all for the CoCo though, and all Tandy-labled disks in Tandy jackets still...and some are even for OS-9. They are: Flightsim I, (c) 1984 Multiview for OS-9 L-II, (c) 1987 OS-9 Pascal Disk I & II (version 02), (c) 1983 C Compiler for OS-9 Systems (version 01), (c) 1983 Color Disk EDTASM (version 01), (c) 1983 Ghana Bwana, (c) 1984 OS-9 Profile, (c) 1984 Biosphere for OS-9, (c) 1985 At least now I've got a few CoCo disks to try once I finally find a disk controller for my III!

Wanted -- Atari ST 1040 drive

by manney＠nwohio.com

A customer's Atari 720 K 3 1/2" floppy drive died. Anyone have one? According to him, this takes standard IBM DSDD 720K drives, but not Tandy (I guess, because of the strange data cable.) Thanks, manney(a)nwohio.com

weekend additions

Message text written by INTERNET:SUPRDAVE@aol.com >i also picked up something called a mattel aquarius for $10. the box was still sealed up, even the staples were intact! i havent used it yet. any opinions on the copy option board or the aquarius would be welcome. < I'll send you e-mail on this, but for the benefit of anyone else: I happen to maintain the FAQ on the Aquarius, and on the "add-on" computer keyboard for the Mattel Intellivision, known as the ECS. Since you have the manual, some of the information in the FAQ will be duplicative, but some could be very useful. For instance, depending on the package you got, the Aquarius does not come with the cable needed to hook it to a cassette recorder. From the (brief) description in the manual, the cable SOUNDS like the Radio Shack cable-- five-pin DIN connector on one end, and plugs for the cassette EAR, MIC and REMote connectors on the other. Unfortunately, the Aquarius cable is NOT wired the same as the Radio Shack cable; and, the manual doesn't supply a diagram of any Aquarius ports to allow you to easily figure it out yourself! The FAQ explains how to make your own. Also explained is how to attach a serial printer (either a DB-25, or a Radio Shack printer intended for use with the CoCo) to the Aquarius. (The Aquarius printer port is quite unique: it's a mini-stereo socket-- just three separate lines.) Gil Parrish 107765.1161(a)compuserve.com

TI-99/4A Cartridge Lifespan

by 107765.1161＠compuserve.com

Message text written by INTERNET:classiccmp@u.washington.edu >I managed to get at least of the necessary pieces to have a usable TI-99/4a although I think I've don't have the proper pieces for video, since all I get is B&W.< It's probably not worth your effort to mess with a malfunctioning /4a; get another one. I see these units ALL THE TIME in the $3-$4 range, and I don't even pick them up because I already have more than I'll ever need. The trick with the TI is to find the "expansion box", particularly one well populated with cards; that adds (with the right cards) 32K memory, 1 or 2 disk drives, and serial/parallel ports. (Obviously, you can expand it more if you want to get serious about the TI, but this is the "plain vanilla" disk system.) Then you can run disk-based software without dealing with cartridges all the time. Still, you can have some fun with a non-disk system. The cartridges can allow you to do serious work and save the output to tape. There is also an adventure cartridge that contains the basic parser, etc., and then the different adventures can be loaded from tape. A nice setup for a small-memory computer. By the way, your cable might be your problem on having a monochrome picture. Many of the old home computers put out a monochrome signal on one of the pins, and a color composite on another. Gil Parrish 107765.1161(a)compuserve.com I'm wondering why of the six cartridges I've got three work just fine. Two don't work at all, and one "Parsec" works if I fiddle with the tuner on the TV after it's running, yet the initial screen that lets you choose BASIC, or the game is normal. Is this a indication of dead carts or a problem with my computer? What is the estimated lifespan of the standard cartridge, and how can environmental conditions effect this? Thanks, Zane <

I'm prepared to - I get my money's worth anyway (technical data for my several PETs, VICs and my 64), and I would be quite happy to see the stuff go PD thereafter. Returning briefly to the Commodore B series, how do the 8200 series machines fit in? I see old documents refering to the B and P series, and older ones refering to the 500 and 700 series (I think respectively), but the machines I've actually seen from that period are called 8296. There were two models that I've seen - the 8296D (with internal disk drives) and the 8296 (without). The motherboard is identical - two banks of 64k RAM, (I think) a high speed (2MHz?) 6502, and a couple of chips which you unsolder and move to adjacent positions for 40 column mode. The case is similar to the 8032SK - rounded, plasticky PET case with large green screen and separate keyboard, but returns to the edge connectors for the IEEE488 and user ports. The internal disk drive - which I have now added to my 8296 to make a D machine - is an 8252 (?) which plugs into the IEEE488 internally. Ironically, 8296 had a linear power supply and 8296D a switchmode! So how do the 8296 and the B/P machines relate? Anyone know? Also, how do you do the bank switching to get at the full 96K of RAM? (I think you lose 32K to the screen - very inefficient!) Philip.

You would need a kind sole here with an old R/S catalog to give you the number. You could also ask the operator on 1-800-THE-SHACK. Just give her the model of the computer and say that you don't know the catalog number. ------------------------ Rich Cini/WUGNET - ClubWin Charter Member (6) - MCPS Windows 95/Networking

If interested in such family of CPU's and want to use them as preference, be informed that Motorola use a 68k chip inside its GSM cellular phones (like 7000's and 8000's) I found this info on http://www.ibt.dk/morten/friends/hardware.htm Ciao! ???????????????????????????????????????????????????????????????????????????? ?

Atari 400 / Odyssey ???

by coslor＠pscosf.peru.edu

Howdy: Today I'm looking for anyone that might have ANY old Atari 400 cassettes and cartridge games or other programs. Right now, I don't have a disk drive for this system, but am looking for one as well. Second, I am looking to buy an Atari 800xx system? Let me know if you have one for sale. Finally, looking for an old Odyssey game system. Any and all models are on my wish list... including the original Odyssey 'pong' unit, and the more modern models of the cartridge game console unit. If you have any of the above for sale, PLEASe let me know, and your price you would offer it to me for. Thanks, CORD COSLOR //*=====================================================================++ || Cord G. Coslor P.O.
