Maybe not - Afaik are insurances around the world very heavy regulated - to keep fraud away and to get enough taxes ... Another possible aproach might be to cooperate with insurance companies. Maybe the same way as for old car collections. At least here in Germany some (smaler) insurance companies are offering very interesting deals in cooperation with Verteran associations. One can get an all included insurance for a USD 200,000 veteran car for less than an minimal insurance for a actual USD 60,000 Mercedes. It just took around 15 years of talks to give them the idea how the collectors handle the cars and whats all this old car stuff is about. There are now even premium insurances where they will pay a complete rebuild of the car, even when burned. Even when a 'new' would be cheaper - and all at an afordable rate - thats exactly what a collector want: keep HIS car (computer) not just one of the same kind.

Question: Godbout/CompuPro ram boards

by kaikal＠MICROSOFT.com

Well, both the RAM16 and RAM17 use 24-pin 2Kx8 6116 SRAMs, but I checked the tech manuals and there is no mention of EPROM compatibility. The RAM20 was back to 18-pin DIPs, and all the Godbout Econorams I've seen are 18-pin. In short, no clue...

eBay strangeness

Kai -----Original Message----- From: Bob Wood [mailto:altair8800@hotmail.com] Sent: Wednesday, October 07, 1998 10:29 PM To: Discussion re-collecting of classic computers Subject: eBay strangeness Am wondering if it is me or if everyone is experiencing this? Someone has listed an Altair 4k memory board. The eBay item number is 34468468. Whenever I go to this listing, my computer locks up. It has happened every time I have tried since earlier in the day.

RT-11 on 8" media

>In a box of Stuff, I got 2 cartons of BASF 8".... one of which is >marked "RT-11 V3 System DO NOT OVERWRITE!!!". Congrats... been a while since I've seen one... > All this absurd and useless detail aside... I am wondering if >there is a 'Minimum Set' of files, which placed on a floppy(ies) >would boot a PDP11... and, I am assuming, it would require Sysgenning? It's been so long since I saw a V3 kit, I've forgotten whether it was a version with split monitors and device handlers, or if the monitor had to have the system device built in (and the table for all other supported ones as well). If the latter, than you'll probably need to locate a file with a name of the form RXMNSJ.SYS (for RX01 MoNitor - Single Job). This file, with SWAP.SYS and PIP.SAV and you should have enough to start. You'll have to write the bootstrap on it, which, if I remember correctly, was done with .R PIP *DX:A=DX:RXMNSJ.SYS/O *^C (I don't think DCL was available yet... maybe CCL, but it is clumsy). If the former, then you'll need: SWAP.SYS RT11SJ.SYS DX.SYS PIP.SAV (and the bootstrap, written as mentioned above). > Is there available on the Web this info? There is a faq - I've forgotten where it is located... > Also, I have an 11/73 with RT-11SJ V5.0.... it has an 8" drive. >What would I have to do to make a bootable minimal floppy on this >machine? In other words how few files can one get away with to wake >up a PDP11 with only an RX02 clone as it's mass storage? By V5.0 time, the split monitors/handlers had been long accomplished, and DCL was around, and PIP had been split, so you'll need the following: SWAP.SYS RT11SJ.SYS (or RT11FB.SYS or RT11XM.SYS) DX.SYS (or DX.SYS or DXX.SYS) (plus any other device drivers you want) DIR.SAV DUP.SAV PIP.SAV RESORC.SAV And creating a bootable floopy is as simple as: COPY/BOOT DX0:RT11SJ.SYS DX0: (or substitute RT11FB or RT11XM) Megan Gentry Former RT-11 Developer +--------------------------------+-------------------------------------+ | Megan Gentry, EMT/B, PP-ASEL | Internet (work): gentry!zk3.dec.com | | Unix Support Engineering Group | (home): mbg!world.std.com | | Compaq Computer Corporation | addresses need '@' in place of '!' | | 110 Spitbrook Rd.

Naming things is just a way to classify them, to separate one ] kind of thing from another. So, the first time a term like ] "microprocessor" is coined is due to necessity -- a new thing came into ] being and it needed a name. Applying that name to things that follow is a ] convienient way to establish a relationship to the original thing. Must it be things that *follow*? If another company had independently developed a single-chip CPU before Intel, (say they killed the project because some marketer popped in from the future and convinced them that Wintel would eventually kill it anyway) could you not bring yourself to call that thing a microprocessor? Isn't it the thing's physical properties that should matter, and not its intellectual ancestry? You are not a patent lawyer on the side, are you? :-) ] As far as I know, the name "microprocessor" was first given to Intel's ] 4004. It was just shorthand for "this new thing that has a high level of ] logic integration that gives you a bunch of stuff needed to build a ] general purpose computer." Calling anything else a microprocessor, to me, ] is just a way of saying it's a CPU that is in the same class as the Intel ] 4004: general purpose, highly integrated, commercially available, etc. Actually, it is not clear to me now if you consider that the defining characteristic of a microprocessor is that it descended from the 4004, or that it be single-chip. It looks like the only characteristic that a multi-chip implementation partially breaks here is "highly integrated". Then again, a two-chip implementation is not necessarily much less integrated than a single-chip. Now I wonder why this level of integration matters. Is there something that a two-chip implementation can't do, and a single-chip can? Did people really care about this level of space-savings to the extent that it was worth introducing a new word into the language? Maybe the significant bit was that the entire CPU was in specialized VLSI, and not made from parts so small and generic as to be re-wirable into something else altogether (ie: SSI/MSI). I mean, being reconfigurable is not in itself a bad thing, but if you are using parts that are so small and generic, maybe you have not achieved the level of integration that brings big cost benefits. If we count the non-genericity of the CPU chips as being the relevant feature of a microprocessor, then it is just an accident of history that the first things we called microprocessors were single-chip. Suddenly I like that definition a whole lot more than the one I grew up with. I generally dislike it when people try to redefine words for their own (usually political) purposes. But in this case, it seems we don't have a widely agreed-upon definition to begin with, so I don't feel too bad in changing sides. ] If somebody made a two-chip CPU that had all of the other characteristics ] of the Intel 4004, you'd have trouble calling it a microprocessor, because ] it would be missing something. Maybe you'd call it a two-chip ] microprocessor. If it were special purpose instead of general purpose, ] maybe you'd call it a special purpose microprocessor. But once you make ] something different enough from the 4004 that you need to add a bunch of ] qualifiers, you might as well just call it a CPU or come up with a new ] name. Actually, until ten minutes ago, I would have had trouble calling the two-chip thing a microprocessor because it broke the definition I learned as a kid: single-chip. But even the characteristic of being similar to a 4004 is relevant to the extent that you are careful in choosing which way it has to be similar. The first 4004's were probably in ceramic; should that be part of the definition? Probably not. Why did we care about the 4004? Is being implemented on a single chip really the important bit? Or was it cost, ease of use, small size, ...? A two-chip implementation could very well have been important to us for exactly the same reasons that the 4004 was. I can see that explaining why computers suddenly became cheap and ubiquitous could be useful. But the "single-chip" definition of a microprocessor is only circumstantially related to that. If the 8080 and its cousins had actually been multi-chip implementations, things would have progressed exactly the same way. (And pigs with wings *would* be eagles, dammit! :-) ) So, when is it useful to distinguish single-chip from, say, dual-chip? What kind of practical decision would someone make based on that? ] -- Doug Cheers, Bill. BTW, was the 4004 really the first in the Intel series of 4004, 4040, 8008, and 8080? I seem to remember that something in this sequence actually happened in non-ascending order, like maybe the 8008 preceded the 4004, or the 4040 came out last, or ...? It could make sense; you could imagine scaling back an existing design to penetrate some niche market with a cheaper part.

RT-11 on 8" media

by jpl15＠netcom.com

Some Newby-ish questions, if it so please The List: In a box of Stuff, I got 2 cartons of BASF 8".... one of which is marked "RT-11 V3 System DO NOT OVERWRITE!!!". And inside are 7 floppies, each with a DIR printout stuck in the envelope, (and the DIRs look like typical RT-11 files). These disks are numbered 21 - 26 and 30. The other box has no IDs of any kind, save three diskettes are labled 47, 49, and 50. The other 7 are unadorned, but they appear to have been spun... there are faint burnish markings on the surfaces. As an added, extra bonus, there is a listing of an 18-line Basic program which "Determines if One Number is a Factor of Another".... surely an unexpected blessing. All this absurd and useless detail aside... I am wondering if there is a 'Minimum Set' of files, which placed on a floppy(ies) would boot a PDP11... and, I am assuming, it would require Sysgenning? Is there available on the Web this info? Also, I have an 11/73 with RT-11SJ V5.0.... it has an 8" drive. What would I have to do to make a bootable minimal floppy on this machine? In other words how few files can one get away with to wake up a PDP11 with only an RX02 clone as it's mass storage? Bowing before the Silicon Slippers of the Knowledgeable Ones, Cheers John PS: Learning all the time..... TIA!

Eventual fate of our machines

> >there is no one to carry on the tradition. I shudder to think about the >eventual fate of all of our collections. Do we need a national repository >for all of this stuff? How about a collector's organization which can act as a willed beneficiary for collectors. A board of directors can act in the best interest of the collection should a member (or non-member?) die and bequeath(sp?) his/her computer collection to the organization. Some items can be kept for a museum piece while others can bid for a chance to purchase the remaining items. This could fund the organization. The organization can also conduct interviews with bidders to determine if they are serving the best interest of the computer collection if they get the desired item. A clause can be put in to require the item to be retired to the organization upon their death. Some of the funding can also be used to provide insurance coverage to members by people who know the value of what's being insured. Just my thought, and is well open to discussion. Jeff Salzman >

Apple 1 6800/6502 (RE: kits, definitions, prices...)

by kaikal＠MICROSOFT.com

It's pretty clear if you look at the board. Note 7 in the Processor Section Schematic elaborates thus: "7. Unit, as supplied, includes a 6502 microprocessor, and solder jumpers at both points marked '6502', and has omitted all components shown within the dotted box. If a 6800 is substituted for the 6502 it is necessary to install all components shown, and to break both solder bridges labeled '6502'." The "dotted box" refers to a normally unpopulated area of the board. The components shown within the "dotted box" are just 4 transistors and a handful of resistors and caps. Remember that the 6502 was largely an electrical clone of the 6800 with a different instruction set. Obviously the supplied monitor ROMs wouldn't have run on the 6800, but the monitor source is supplied and could be translated.

Latest finds

by wanderer＠bos.nl

Well, let's see. I got the kit for 50 guilders ($25), which is not a bad price if you ask me for such a near complete kit. As for the moment, I don't have a picture yet, but I could scan a picture from one of the manuals. Unfortunately it's not fore sale, but if someone want's to exchange it for a KIM-1, I could be tempted, or somewone would like to pay me mega $$$$ (maybe someone at eBay :-) ) Some more info about the board, it's labelled PWB 10010505 Rev C and has a copyright of 1976. The manuals have various dates, they are : Product Description book, dated January 1979, Assambly Language Reference Card, dated March 1979, MCS-80/85 Family User's Manual, dated October 1979, 8080/8085 Assembly Language Programming Manual dated 1977,1978, 197 SDK-85 System Design Kit User's Manual, dated 1978 Regards, Ed BTW, the guy who sold this also had 3 handheld terminals sets which doe work on CP/M. He also had 3 matching printers, 2 software development kits for the PC (has a Z80 processor on an ISA board), and 1 docking station. Apparently these sets were used f.e. as barcode readers, as the terminal could be equipped with a optical pen. -- The Wanderer | Geloof nooit een politicus! wanderer(a)bos.nl | Europarlementariers: http://www.bos.nl/homes/wanderer | zakkenvullers en dumpplaats voor Unix Lives! windows95 is rommel! | mislukte politici.

I shudder to think about the > eventual fate of all of our collections. Do we need a national repository > for all of this stuff? National Repository ? Like a landfill at Mt. Rushmore ? Serious: I think it's a) mor than just a 'national' issue, and b) giving your legacy to any kind of 'big' museum / collection wouldn't be better than auctioning every single piece for maximum profit (for the heir). Let me explane the last one. At first, a 'big' collection, like a museum (and I just assume there will be in the future some computer museums at least the size of car collections) will have already more than 95% of your (or mine) collection, counting the CPU's, so they only need 5% for display. The rest will be surplus or spare parts in best case. Second, they will have, for shure, already more computers and accessories than they are able to display. So yours might never be seen again autside the warehouse. Third, (and most important in my eyes) 99% of all of the hard to get software and documentation will never go on display And last but not least, even if one of your computers get on display, they might refurbisch in a way you would never liked - removing stickers, that you saved as a sign of Zeitgeist of this machine, or even canibalise it for display. For example: The Deutsches Museum in Munich has a quite astonishing collection of old machinery on display, but compared to what they have in storeage, it's like showing a Apple Mac Plus as a representiv for everything Apple produced - from Apple 1 until Newton ... - Even for old Computers: they have a quite impressive collection of uP based Computers, but just an PET and an IBM-PC on display (within more than 5000 sq ft computer display). (To be honest, every of the things above can happen also with smaler collectors, but I think they are more likely for big collections/mueseum.) Personal I have not decided what to do with my collection (althrugh I alredy have a last will where several persons are picked to get some parts or to be responsible for the distribution). Possible ways where I feel comfortable are: a) Let 'em all on auction after my death for maximum money. b) Pick people for every parst to inherit to. c) sell them among fellow collectors for their real value. That means for example 100 USD for a C65 or a chicklet PET. d) If I ever will archive my own museum, building a base, where inheritance is no question, because it exists on it's own behalf. The idea behind b) and c) is just to give them to people who don't want them pure for the market (ePay) value, but for the thing itself. c) has an advantage, because I belive buying is better than getting a gift. In fact, if I haggle for an Apple 1 at 100 USD it's more fun than getting the computer for free (dont get me wrong - I wouldn't deny any free computer :).

But won't the mony winn over the idea ? Altrough I belive, that certain organisations, like government, unions, etc. are neccersary, I dislike most organisations, since every one of them tends soon to put the organisation itself on top of the mission. The organisation becomes the mission instead of serving it. This is especialy true for (so called) privat (NGO) organisations without true public control. The process is called professionalisation. Enthusiasm fades, and business is the rule. Maybe I'm a bit negative, but I have no trust in any fixed long time perspective organisation supposed to do 'fun' (non comercila, ethusiast) things (So, Sam, if there is a planned membership for VCF, I'm out :).

Kaypro 10 HD woes

by jpl15＠netcom.com

One of my Kaypro 10s has a bad case of the dreaded 'Spindle Stiction', ie. it won't spin up on it's own. I have learned to smack it in just the right place, to produce a radial moment normal to the plane of rotation, and then it spins up and boots. The first time I did this, I backed up the drive to floppies, so if the drive dies for good, no big deal. Allison, I believe, was the person who discussed this fairly common problem, some months ago. And since starting a drive with the handle of a big screwdriver can only be termed *abuse*, it's amazing that the poor thing works at all. But try this, in case there is something wonderful living on the HD, before you format it. (If in fact the no-boot is caused by stiction....) Cheers John

This is what wills are for, insuring that your stuff is taken care of the way you want it to be taken care of. One way to do this in the US is with a 'living trust.' You create a trust and transfer title of your collection to it, in the trust you and your wife are trustees. Then you specify a successor trustee (say some local technology museum) and then when you are gone the control of the assets moves (without probate!) to the sucessor trustee. In the trust you can limit what the trustee can do with the trust assets, including disposing in landfills. --Chuck

(Intel seems to use the term "MCS-8" very loosely in the literature I have.) There was also a single board computer, Sim8-01 with 2k bytes EPROM and 1k byte ram. It could be used with a MP7 EPROM (1702A) programmer. Another company was Martin research which made "Mike" series computers. Haven't found any of these either, but did find by inter-library loan their "Microcomputer Design" book, which has lots of 8008 info! It has a schematic of their "Mike 4" system, an 8008 based unit with about 20 ic's. It also included other minimal 8008 systems such as a 9 chip version. I have found a source for 8008 chips, so maybe a homebrew 8008 system is more likely as a future project. -Dave

Eventual fate of our machines

by Marty＠itgonline.com

I belong to the Mid-Atlantic Antique Radio Club which has established the Radio History Society, a non-profit musuem, which is located at George Washington University in Washington, D.C. The Radio History Society http://www.radiohistory.org/ is an IRS 501(c)(3) organization which can provide donors with a tax deduction. A single friend of mine has decided that he will donate much of his collection to RHS when he passes on as nobody in his family is interested in old radio. Anyway, I'd imagine CHAC and other organizations can offer help in directing people to good homes for their gear. Marty ______________________________ Reply Separator _________________________________ Subject: Eventual fate of our machines Author: classiccmp(a)u.washington.edu at internet Date: 10/7/98 11:09 AM Has there been any discussion about the eventual fate of our collections after we are gone? My wife and I have discussed this at some length. I see three phases to my collection. Phase one: Active procurement (Present state) My collection currently exists in a very unorganized state in my basement. I have no real inventory list. Phase two: Active display Fully inventoried with a list of what works and what doesn't. We've discussed the possiblity of setting up some sort of cybercafe to help pay for maintaining the collection. Phase three: Finding the collection a new home (After I'm gone) This is the tough one. In the wrong hands the collection might just go to a landfill and that would be a real shame. I have no kids so there is no one to carry on the tradition. I shudder to think about the eventual fate of all of our collections. Do we need a national repository for all of this stuff?

Top 10 Holy Grails of Classic Microcomputer Collecting

by allisonp＠world.std.com

< I meant, what was the proportion of each media at the time? No idea, seems biased to tape where I lived (LI NY). < Back in the days of my IMSAI experience, we had both an ASR-33 and < a cassette interface card. I don't remember the relative costs, < though. A cassette interface and deck were less costly than < an ASR-33, even at ham radio prices? 1975-76 time frame a used ASR33 was 500-900$US. The only machines at the ham meets were BAUDOT with 5level tape (and slower), they ran 75-150$US for a good working one. The ACR and a cassette tape were like 199$US and 35-45$US and faster as well. The third choice was an optical PTreader homebrew or commercial and they required a parallel port (cheap or trivial build) and inexpensive. Punching was again a cost thing and the old teletype BPRE punches were a good find at 100-200$. The point being things we take for granted as cheap or available now (or during the 80s) were less common and expensive in the mid to late 70s. Back in '76 showing up with some kind of terminal storage and more than 4-8k of ram and Basic generally put one in the fortunate class. My altair by late '75 had a home made ascii keyboard attached to a MITS-PIO and a modified (for 64char, 16line) SWTP CT1024 and a MITS 88-ACR and 12k of very flaky (solder plated edge connector rot) 88-S4k ram. I was able to run MITS 4kbasic, 8kbasic and Programming package II. That for its time was a power system. A bit more history... the other systems seen at the time that were pretty neat were the AMI EVK series (6800 SBC with decent amount of ram and rom) and the SWTP 6800. I havent seen either one in years. Both were pretty nice systems and less hardware intensive for the user. It seemed to me at the time that the 6800 camp were doing more software work and the 8080/s100 camp were into hardware. Anyone remember the Viatron systems that were turning up surplus around '75-78 time frame? It used tape and had a multichip LSI cpu. Allison

For sale stuff gone.

OK, all of the stuff is now spoken for. I had to flip a few coins on some of it, as there was demand for some of the things. Sorry to anyone that lost the coin toss - I wish I had more. I am still looking for those IBM 5103 ribbons. William Donzelli william(a)ans.net

Tron, con't

by jfoust＠threedee.com

Regarding Tron and the recollection of friend-of-a-friend-who-worked there anecdotes, it reminds me of what's still happening in the computer graphics business today: everyone wants to take credit for what's on the screen. For example, the company I work for, Viewpoint DataLabs <http://www.viewpoint.com>, did the modelling for the recent movies Godzilla and ANTZ. What does this mean? It means our artists and 3D modelers created some of the data used by some other company's animators. Of course, our PR people trumpet the fact that Viewpoint made Godzilla. Well, we made the computer model by digitizing and finesse-ing some big rubber scale models made by someone else. And it goes on and on... some other company does the animating, someone else does the rendering, someone else does the compositing of real and fake images, someone else produced it, someone else funded this or that, someone else's 3D software was used to render it. At Siggraph, the industry's big trade show, the Kingston memory chip booth wasn't far from our booth, and they spent the week telling people to buy their memory because it was used in the machines that rendered scenes from Titanic. Back to Tron, though - three-four years ago, I remember meeting someone at a Siggraph who claimed to have worked on Tron, and who still had a copy of the original computer 3D models. I think he was a Caucasian wearing a robe and Sikh-like turban, but my memory may be faulty. If the truth is ever documented, I'm sure Tron was assembled using what equipment they could afford, and whatever could get the job done to the satisfaction of those paying the bills. - John

You might be able to use any 10Mb (or so) external SCSI drive, I'm not sure about that though. I can get the connector pinout from mine, I haven't taken it apart yet so I don't know what Hard drive it takes. I could chek if nobody else has the answer ready. Experts please?

Top 10 sins of a computer scrapper

by Innfogra＠aol.com

Mea Culpa, Mea Culpa. I have sinned. I am retireing after 10 yrs of reselling computer, test and laboratory equipment. It was with interest and dismay that I read the top 10 Holy Grails and the following threads. After ballooning up to 16,000 sq. Ft of warehouse my partner insisted on scrapping large parts of the inventory. I was an accumulator, he was a scrapper. Needless to say we didn't last. Unfortunitely during that time we destroyed a lot of older computers including a Xerox Alto, I recognized it later on Revenge of the Nerds several Xerox Stars, I have some of the factory software left and maybe a mouse. a Magnolia Jaquard 100 Word Processor Used the 4004 computer chip Unknown SBC with an 8008 chip, I saved the chip (Std bus I believe) 3 IBM 5100s Scores of early Intel development systems including several Prompt-48 and MCS-8, we bought large lots from Intel Chameleon, I may have a manual or two. Litton 1251, Dual drum memory 400K, punch tape programmed PDP-8 Several Teraks Cincinatti Millichron 2000, I may have a programming card left I'm sure some of the big iron counts but I didn't know that field well. OK so this is more than 10. Where were you guys 4 years ago? I'm really sorry for my part.It is really hard to figure out what is collectable, particularly if you don't recognize it. I felt really bad when I finally recognized that that funny looking Drive with Xerox on it. Is there any interest in a DEC VAX 730, a General Automation Zebra 5500 (a Pick machine), DEC RA60 & RA81s, Tektronix 4113, NCR 1000. These need to go very soon. I enjoy the list. Thanks a lot.

North Star Horizon Help

< Ok, I have a few minutes now to play around with the N* Horizon < I've been fixing up. I've tried to power it up and it seems to hit the < disk drive and then nothing. I've plugged some spare terminals into < the port marked "Video Terminal Port" and played with baud rates < and other comm settings but get nothing on any of my terminals. There is no resident monitor or software other than a disk boot in a standard horizon. It will not say anything to a terminal untill it boots (assuming the booted code has something to say). If the boot fails likley the only signals you get is disk activity or the lack of it. Make sure you have at least 32k of ram starting at 0000 for CPM or 16k starting at 2000h for NSdos. < Also tried straight through and flipped comm cables. Can < someone give me some info on these and maybe walk me through < getting it set up and running so I can check and see if I've missed < something? Oh, I'm trying both N*DOS 5.2 and N* CP/M 2.2. Are they personalized for the machine and are all the port headers don on the mother board set up correctly? Are the media the correct density for the controller in use? I have and still run one. it occurs to me, if you have DOCS for it the setup and checkout procedure is in there. Allison

The PC card were between sheets of cardboard and it was all in a box with a xeroxed 4th generation manual with atleast two erata sheets for each board. Not much to look at. Some of the later 8800a and the 8800b machine had some nice bent corrigated and all. Allison

Rookie PDP help needed again...

< The only thing on the board is what's on the handle; "M8186". There is < circular sticker on the underside of one handle that says "mpg jun/81" < it.

Although it's certainly interesting, I doubt my new-found knowledge of the first microprocessor is going to radically change any of my view of the world. F14CADC doesn't mean anything different than 4004. But, what I guess might be significant is that this shows how major an impact the military has played on computers. The ENIAC, F14CADC, DEC Alpha, and other stuff I'm sure can all be attributed to the pentagon. And _that_ is significant because instead of saying that the computer is a triumph of enterpreneurs and daring capitalists, we can _also_ say that it is a triumph of America's great war machine. > >the F14 CADC was the first microcomputer system that made fly by wire >practical.

Apple IV/Lisa (was: Re: Somebody has a C65 on eBay)

by tomowad＠earthlink.net

>>>There's some evidence to suggest that the Lisa is the Apple VI, which raises >>>the question of what happened to IV and V. >> >> I think it would be more accurate to say that Apple considered naming the >> Lisa the Apple IV. "Lisa" was originally just a code name, after all. > >In what way can that be said to be more accurate? "...Lisa is the Apple IV" gives one the impression that the Apple IV was a definite computer, rather than just a name that was considered, but never actually used, for the Lisa. It is quite probable Apple considered using the name "Apple IV" for many computers that shipped after the Apple ///. Said Steve Wozniak, in reference to the Apple ///, "...when we reintroduced it we should have called it the Apple IV." (The Mac Bathroom Reader, pg 34). My point is, "Apple IV" is such a logical name for a computer from Apple that it could have been considered for just about anything. "Apple IV", however, is not the sort of name that was used as a codename at Apple, and therefore most likely would not have been called so in the development stage, though there are many prototypes that could have ended up bearing that name. Of course, I'm just hypothesizing here. :-) >Aside from the marketing model numbers, the only information I've ever found >regarding alternate names that may have been considered was the story about >the name "Applause". According to _The Mac Bathroom Reader_, by Owen Linzmayer, page 80: "Apple figured it needed a more professional-sounding name to appeal to the business market, so it hired an outside consulting firm to recommend a new name. Among others, they suggested Applause, Apple IV, Apple 400, The Coach, Espirit, Teacher, and The World. Quite an effort went into thinking up a different name, but the forthcoming computer had already received so much press coverage under its code name that Apple reverse engineereed the explanation that Lisa stood for 'Local Integrated Software Architecture'" If you're interested in reading about Mac History & prototypes, _The Mac Bathroom Reader" by Owen Linzmayer and _AppleDesign_ by Paul Kunkel are both excellent books.

Aquarius Data Recorders

by dlw＠trailingedge.com

I just received an email from a local group which has 250 new in box Aquarius cassette recorders. They are taking bids but I suspect you can't just buy a few but would have to take the whole lot. I have one but could use at least one more and maybe two and it would be nice to have the box and any doc or cables. Is there any interest in this out there? If so, how much would people be willing to pay? Don't forget shipping costs. Let me know.

Top 10 Holy Grails of Classic Microcomputer Collecting

by foxnhare＠goldrush.com

Let's get this into the proper perspective here there is only one "Holy Grail" (unless you read National Inquirer then there are millions for $39.98 plus shipping and handling) Let's see if I can think of some true 'Holy Grails' of computing: 1) The pre Apple 1 prototype Steve Wozniac brought to the Homebrew Computer Club. 2) The original code listing for the BASIC he hand typed to demonstrate that computer. 3) The PDP-1 used to write and play Space War at MIT (with the original game controls) ( I know it's not a micro, but I like the idea. ) 4) 'The original' paper tape of BASIC that was pirated from Bill Gates. Now those would be 'holy grails,' something along the lines of you either don't tell anyone or are very carefull who you tell that you own them.

Commodore was almost to production before they decided to drop the C65 (I remember reading 1991 as the year they dopped the project). After Commodore went bankrupt some of thier warehouse assetts were liquidated, the Graprvine Group in New York had bought the one with the most c65s and were selling them for I think about $100 a unit. It kinda resembles an Amiga 500 with the floppy drive facing forward (no neumeric keypad). The c65 would best be compared to the Apple IIgs, still has its roots in the 6502 but alot of the graphics and sound are adapted from Amiga technology. It would have done well with the people wanting a more amiga-like system without sacrificing all thier Commodore 8-bit drives and such. There are enough c65s out there that some people have FTP sites of c65 programs. Unfortunately I wasn't one of the people who got a c65 on time. *sigh* -- -+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+- Larry Anderson - Sysop of Silicon Realms BBS (300-2400bd) (209) 754-1363 Visit my Commodore 8-Bit web page at: http://www.goldrush.com/~foxnhare/commodore.html -+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-

It *certainly* wasn't obvious in the mid-70's, when Intel had picked up its pieces and put together a microprocessor chip (the 8080A) which cost a significant fraction of what a new car cost at the time, that VLSI CPU's were going to be replacing boards full of TTL logic. It was Intel's competitors - notably Motorola and especially MOS Technology - who were responsible for driving microprocessor CPU costs to the hundred-dollar-level and below.

I think it's helpful to say that a computer is any implement, mechanical or otherwise, to aid in calculation. But this means rocks, fingers, and calculators are all computers. I guess we can say, any machine which is capable of performing something besides addition, mulitplication, subtraction, division without further input from the user. Thus, I guess a computer must either have stuff like that hard-coded (like a slide-rule) or be programmable. So, from this 1-min. train of thought, I say: A computer is any implement capable of processing super-arithmetic functions. BTW, my New Bantam English Dictionary says: A machine capable of performing highly complex mathematical calculations at very high speed. >calculator, reckoner. spec. a person employed to make calculations in an >observatory, in surveying, etc. >1646 Sir T.

Rookie PDP help needed again...

by aaron＠wfi-inc.com

Thanks for the other responses about the cards, I think I have all the Plessey clone cards identified with the DEC models. However, I am a little confused on my CPU board identification. The board is an M8186, which I have searched on and found to be a KDF11-AA. Or KDF11-AB. Or KDF11-AC. The problem is that I can't find any revision code on the board. To add to the confusion, the original configuration sheet in the case lists the CPU board as a KDF11-HF, of which I haven't been able to find any info at all. Does anyone have any info on this CPU, or can you tell me how to identify which board it actually is? Also, I have looked everywhere for a CPU/OS matrix and haven't found it. Could someone provide me with a URL or just a quick hand-rolled list of what versions of which OS run on which processor? The multifunction board is Plessey #MFV11A; same as DEC MXV11A? I tried to make a console cable using the pinouts on the sunsite PDP-11 page with no success, setting the terminal at 4800baud. Is there something I'm missing here, or can someone suggest how to wire the cable? I just arranged a loner scope (my Tek is basically dead), so I'll start going pin-by-pin until I figure it out, but a "here's how to wire the cable" would sure help a lot. Finally, is there anyone who remembers these clones? Does anyone have _any_ documentation on them at all? Anything really different from a standard DEC PDP-11? The front panel calls it a "Plessey Periperal Systems - Micro II." It has 6 switches on the panel: write protect switches for the two internal 8" floppies, the cpu halt/enable switch, a boot switch, an LTY on/off switch, and the power switch. Any info at all would be greatly appreciated. I feel like I've just stepped into the pages of a wild adventure book... Aaron

So do you judge Xerox's impact on the "personal computer" as their Xerox 820 II or 8/16 machines or by the impact PARC had on user interface metaphors? One of the more subtle things that this sort of blanket statement misses is that places like the Silicon valley are filled with folks going from job to job and bringing their knowledge (some of it classified) with them. Xerox had a tremendous impact on Sun because a lot of ex-Xeroids went to work there (look at a Dandelion box and a Sun 3/160 sometime :-) The impact of Ray's design could be indirectly felt by people who worked with him and went elsewhere. --Chuck

RSX-11M and CSR's

by mbg＠world.std.com

I think RSX has something called autoconfig which will tell you how your system is configured (apparently by actually touching the hardware).... RT-11 can only tell you a part of the information, and only if it matches the configuration of the handers... SHOW CONFIG will tell you about the machine itself (processor, memory, fpu, etc) while SHOW DEVICES will list all the devices for which at least the CSR the handler knows about responds... even if the CSR is the wrong one for that handler...

The market that intel couldn't or didn't care to be in was the $1 single chip microprocessor market where TMS1000, COPS, uCOM4 and other 4bitters can and did have a distinct presence. Allison

Top 10 Holy Grails of Classic Microcomputer Collecting

by altair8800＠hotmail.com

I received a tip last year that a long time computer business located in Mobile, Alabama was a virtual storehouse of vintage machines. I payed them a visit and could not get past the receptionist. I was told that they occasionally donated the things to be used in educational institutions but that they were absolutely not interested in selling anything. About six months later I learned that the business had closed. Subsequently, I was told by a veteran employee of this firm that when they shut their doors they hauled two Xerox Altos (among many others) to the landfill. I told this person that it was unlikely that they would ever have been in possesion of Xerox Altos but he was adamant that they were indeed Xerox Altos. In hindsight, I now wish I had fibbed to that receptionist and told her that I was connected with the University of Alabama.
