I ran some service calls on Columbia pc's around 1987. As I was raised in the Washington, DC suburbs (Silver Spring, Maryland) and had been to Columbia, Maryland (which is located halfway between Washington and Baltimore many times, I was surprised when reading the documentation of the pc which stated it was made in Columbia, Maryland. Several years later I needed to order a replacement motherboard and discovered they had moved to Florida.

Its nothing to throw down $25 o < $50 if you're getting a manual and support with that. The KIT was $500, but that only got you the box and a CPU. Ram was expensive then and the IO was either serial, tape, or parallel so you also needed a TTY or CRT(I used CT1024). Still BASIC for MITS prices was ok but as Billy's price it was out of reach. FYI at the time of the article (early '75) a system with 32k of ram, cassette and serial IO would be over $3500! The 8800 was cheap, but not that cheap. Three years later (early 1978) that price would have dropped to 1500 or less due to the lower cost of memory boards and the lower cost of the system itself. The Disk system would be around late '76 early 77 with software to lag behind it. In 1977 you could get languages, for far less than $100 and many offered features that MSbasic did not have. Examples of this were PT basic, Focal and NS* disk BASIC. Also Tiny basic was published along with a little later LLL8k Basic as examples of free software with sources available. That trend nearly killed MS and did put a few others under. It was very hard to make a buck on paper tape or cassette based software. Affordable disk systems opened up the market and made it a serious force for applied software. Allison

< > < > for a intersil 6100 (12 bit pdp-8) based system. < > < < < Do tell. A small potload of them for the Intersil sampler, there was an article in Microcomputing December 1979 (P54), also the intersil data books and schematics for some of the board level porducts and app notes. Also several megabytes of PDP-8 software and a DECMATEIII to run it on. < That wasn't memory mapping. The 1861 DMA'ed the video data out. No, that was how it transfered the data to the CRT (it would read memory with DMA and serialize it add sync and all). the User would write data to the memory map that was display memory to change the pattern on the screen. That makes it memory mapped. the fact that it used DMA was a simplification of the hardware. < I saw one at the Computer Museum of America, but I don't think it is < available. There are still a bunch around. They only made maybe 20-30,000 of the 8E/8A series. < Well... they _were_ nice and bright. Ah, the countless hours I spent < staring at those ember-bright dots, counting toggle pulses in my head < to fix a one-byte bug. First thing I added was four more to latch the address. < Ob1802Trivia - don't execute the one "missing" instruction, 0x68. ISTR < that the CPU went berserk and whomped memory randomly. Well, all of the 6Xh instructions manipulate the X register directly or indirectly. 60 inc X R(X)+1->R(X) ! memory pointer pointed to by R(X) is ! incremented What's significant is the operation is a dummy output but since having the N lines with 000 on them was a nop all it does is increment the pointer. 61->67 out M(R(X)) ->BUS; R(X)+1 -> R(X) Effectively output a byte pointed to by R(X) to the device and increment R(X). The N lines will have a value of 1->7 depending on opcode. 69->6F input BUS -> M(R(X)); BUS -> D Now... the cosmac uses the high bit of the N register to signal internall that the instruction is a input so.... 68 inpGarbage BUS -> M(R(X)); BUS -> D In this case bus content is undefined so you just trashed the accumulator (D) and the memory pointed to by R(X). On my system due to the pullups on the bus and all that meant a FFh was loaded every time. Handy way to stuff a -1. The COSMAC is a real simple machine and it's behavour is very predictable with one general exception... The CMOS process in the late 70s had horrendous propagation delays and the timing of the chip was very variable with voltage. So at very fast clocks the timing on some signals could have a negative setup at one voltage and a positive setup if the voltage was higher. I know of few people that ever ran successfully at the rated maximum. At moderate speeds it was easy to use. Allison

Why three of each... at one point S4Ks were offered less rams to anyone that had 88MCDs at a ok price. I was able to make them acceptably reliable by pulling the Drams and putting in compatable static parts (NEC uPD410). The board layout still stank and the general noise level on the bus didn't help. Up grading the bus to a WAMCO or compupro with terminations helped. Replacing the whole machine with a NS* Horizon was a vast step forward. Allison

> Bill Gates, in his "Open Letter to Hobbyists" mentioned earlier, tells And for those who don't have the issue of BYTE that this appeared in, here's the letter. Note the "old" address in New Mexico, and the hyphenated version of "Micro-Soft": AN OPEN LETTER TO HOBBYISTS February 3, 1976 By William Henry Gates III An Open Letter to Hobbyists To me, the most critical thing in the hobby market right now is the lack of good software courses, books and software itself. Without good software and an owner who understands programming, a hobby computer is wasted. Will quality software be written for the hobby market? Almost a year ago, Paul Allen and myself, expecting the hobby market to expand, hired Monte Davidoff and developed Altair BASIC. Though the initial work took only two months, the three of us have spent most of the last year documenting, improving and adding features to BASIC. Now we have 4K, 8K, EXTENDED, ROM and DISK BASIC. The value of the computer time we have used exceeds $40,000. The feedback we have gotten from the hundreds of people who say they are using BASIC has all been positive. Two surprising things are apparent, however, 1) Most of these "users" never bought BASIC (less than 10% of all Altair owners have bought BASIC), and 2) The amount of royalties we have received from sales to hobbyists makes the time spent on Altair BASIC worth less than $2 an hour. Why is this? As the majority of hobbyists must be aware, most of you steal your software. Hardware must be paid for, but software is some to share. Who cares if the people who worked on it get paid? Is this fair? One thing you don't do by stealing software is get back at MITS for some problem you may have had. MITS doesn't make money selling software. The royalty paid to us, the manual, the tape and the overhead make it a break-even operation. One thing you do do is prevent good software from being written. Who can afford to do professional work for nothing? What hobbyist can put 3-man years into programming, finding all bugs, documenting his product and distribute for free? The fact is, no one besides us has invested a lot of money in hobby software. We have written 6800 BASIC, and are writing 8080 APL and 6800 APL, but there is very little incentive to make this software available to hobbyists. Most directly, the thing you do is theft. What about the guys who re-sell Altair BASIC, aren't they making money on hobby software? Yes, but those who have been reported to us may lose in the end. They are the ones who give hobbyists a bad name, and should be kicked out of any club meeting they show up at. I would appreciate letters from any one who wants to pay up, or has a suggestion or comment. Just write to me at 1180 Alvarado SE, #114, Albuquerque, New Mexico, 87108. Nothing would please me more than being able to hire ten programmers and deluge the hobby market with good software.

I've forgotten who else attempted to answer the question - Tony's was by far the best reply - but one or two things need clearing up. Person who said check continuity between centre pin of socket and ground on the machine. That tells you if it _is_ connected to the ground plane. Sam wanted to know if it _should be_ connected - i.e. he seems to be adapting a machine for which he has no PSU to work with a PSU he has. Person who talked about safety earthing. All true, but I think the question was about the ground plane within the machine, and whether it should be connected to the negative supply rail, not whether the machine needs to be earthed. Tony: Agreed 99%. But there are one or two exceptions as you imply - wasn't it you who eold me about the machine which regulates the negative rail with a -5V regulator and makes that the ground? The positive rail is then +5V and the unregulated negative is around -5V for serial ports and things. If the supply you are using is a regulated 5V supply, then + and - terminals go to +5V rail and ground plane respectively. If it is not, try and trace supply rails back to a regulator. It should then be possible to work out which way the regulation is done. But as Tony says, in 99% of machines the answer is yes. If you tell us what the machine is, there will probably be someone on the list who can tell you how to wire it up. Philip.

It sold, and will be remembered, because it was IBM's stamp of approval on the (then) latest round of "Computers will change the way you do business." Back then, the theory was "nobody ever got fired for buying IBM" and so it was that even though it was "technologically vanilla", the PC sold and made a serious impact.

Richard Fish (of Ally McBeal) had one in his apartment. BMW's are not exceptional cars. They're fine, much like many others available on the market.

Elf99 - rebirth of a classic

by rcini＠email.msn.com

I'd be interested in one, too. I'd consider a bare board for about $40 with a parts sources listing (particularly for the hard-to-get parts). Modern component substitutions would be acceptable I think.

It's a PDS (Processor Direct Slot). As the name implies, a way to connect something directly to the processor. This means that the card that can be plugged in depends on the processor, and also that designing such a card isn't as pleasant as for ISA or S-100 or others. ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com

Saved Altair 4K BASIC

by allisonp＠world.std.com

< > Entended BASIC - $350 < > w/ purchase - $150 < < Sheesh! No wonder nobody paid for the stuff. These are bloated prices < especially in 1976 dollars. And at current prices a system with enough ram to run extended basic would set you back at least $2000 and that does not include IO or terminal. One caveat, you had to purchase the Altair from MITS and the minimum amount of ram needed to run the package from them too. FYI: in 1977 you could buy a chevy pickup for $6500 to put that price in perspective. The Processor Technology, Digital Group (later TDL) and other folks were turning out software by the pound. It was cheap, good and available. IT was the Gates debacal and people like PCC (AKA Doctor Dobbs) that started the free software revolution and a legacy of so 20,000 free or copyleft programs for the 8080/z80 families alone, likely as much for 6502 based systems.

[OT] Alphaserver Oops!

by DSEAGRAV＠toad.xkl.com

Today, for no good reason, our AlphaServer starts making a funny noise. Sounds like something trapped in the fan, but as long as the box doesn't go down, we're safe. It's our main server. So, being the way I am, I decide on a little surgery with the power on. This is the 1st mistake. So, I open the cover to the disks. (THis is an AS 4/266) Lotta dust in there, gotta blow it out! Reward: Dust in eyes. Lotta fun. Then I spot a little tab toward the top of the case. "Top Cover Latch" Aha! Here's what we're after! So, I unlatch it, and pull the lid off. *CLICK!* Whirrrrrrrrr.... *silence* Seems there's a power interlock in the top cover! Oops. -------

The funny thing is, in 1978 I attended a trade show/conference called PerComp '78 in Long Beach California looking for an 8K BASIC for my Digital Group Z80 system. I talked to Bill, who was there selling BASIC at these ridiculous (to me) prices. He told me that Micro-soft didn't have a version of BASIC for my system. He went further however, and suggested that if I wanted to come work for him he would pay me with the royalties generated by the sale of my version. Needless to say I figured anyone who was trying to sell BASIC (which I figured I could write on my own in about 3 months) for more than a third what I paid for my complete computer was not going to be around long enough for me to collect any royalties... --Chuck

Compaq portable questions (not laptop)

by maxeskin＠hotmail.com

This is the world's first clone of the 5150. It is also the world's first Compaq. You have judged all of the specs correctly. It should be selling for $100,000 on eBay, because it is at least as important as the Altair. After all, this launched the IBM PC-Compatible revolution. I would say this is definitely a must in any computer museum. However, these aren't generally considered valuable. Go figure. >I have recently obtained a machine that when carried resembles a sewing >machine in a carry case, marked Compaq Portable.

Exidy Sorcerer Site Begun

by dlw＠trailingedge.com

Seeing that there is little on the net about the Exidy Sorcerer, I've started to put together my own. So far I've only begun to HTMLize some of my Sorcerer docs. Currently I have almost completed the intro manual which shipped with the system. Just have the last chapter and the appendix to do. Plan on placing other doc and info here as well. I'll also be placing a chronicle of my attempt at building a new expansion box for this system. If anyone has anything they would like to contribute, let me know and we can work out something to get a copy up. You can find it at: http://www.trailingedge.com/exidy ----- David Williams - Computer Packrat dlw(a)trailingedge.com http://www.trailingedge.com

I further suggested that modern replacements >could run as much as $2 or $3 per switch (20 switches - 0 to F, R, L, P >and I). As far as the keyboard encoder chip goes, you wouldn't be thinking of the 74922 would you? It's a 16 key keyboard encoder chip designed, as I remember, to encode a 4 x 4 key matrix. Or perhaps the 74923, a 20 key keyboard encoder (which uses a 5 x 4 key matrix). If some of the non-hex keys latch the 74922 would be more suitable, because I'm pretty sure both these chips can only recognise one key being pressed at a time. Anyway, according to the Australian edition of the Farnell catalogue, both these chips are still available. Farnell wants $A20.48 each for the 74C922 and $A20.52 each for the 74C923 (plus 22% sales tax) in quantities less than 25, and $A14.11 each for the 74C922 and $A14.37 each for the 74C923 (plus tax) in quantities between 25 and 100. However, Farnell is usually the most expensive place to buy components, so I'm sure you'll be able to find them somewhere cheaper (for example, an Australian company called Altronics stocks the 74C922 for $A12.95 each in quantities less than ten, and $A12.50 each for ten or more *including tax*). As far as the keys go, the momentary action (i.e. to 0-F) keys shouldn't be a problem. PCB mount NO push buttons (I think they're called D6 type) switches are available for $A1 each in small quantities. Alternatively you could use a hex keypad. Farnell lists one for $A14.72 (plus tax) in small quantities, so once again I'm sure you could find one even cheaper. That would only leave four of the relatively expensive latching switches to buy. Depending on the price, I'd probably be interested in one of these little machines too.

Oh, now I understand why you were disagreeing with me! Another debate over pedantics...if I go by this, my original statement is hereby revised to 'The iMac is not historic' >Err, no, I was saying that "historic" does not mean "revolutionary". >History reports impactful events more than innovative events. I don't think that the iMac is associated with saving Apple at all. If anyone in the future is familiar enough with the iMac to think it saved Apple, I would expect that the fact it is just a symptom of Steve Jobs' marketing abilities and nothing interesting in itself or even more desirable in any way than any other G3 will also be known. >The iMac will be seen as historic if it saves Apple (and that is yet to be >seen).

Ok, I can only take myself as example, and a Feedback couldn't change the bid in any way. If I want an item I will bid as far as I belive it is worth. An all negative feedback could maybe avoide bidding at, but this hasn't happen 'till now. The way Auctions are described shows way more about the personality then any feedback - especialy when taking in account that americans tend to praise anything that just works out ordinary in bight colours. I also stumbled within the last year across more than one seller with a positive feedback, witch turned out to be a real troll later on. Gruss Hans -- Ich denke, also bin ich, also gut HRK

Hans, Not so much running as freewheeling. The other day I thought mail problems here might have cut me off, so I sent a QUERY CLASSICCMP request to the list server. It said, List CLASSICCMP is locked by owner bskiver(a)u.washington.edu. No list-specific requests can be processed at this time. For further information please contact bcw(a)u.washington.edu bskiver(a)u.washington.edu . So I can't even ask about it, much less do anything. Others have been having similar problems. Philip.

Unknown Apple 2 card

by dlw＠trailingedge.com

Man I have so much to catch up on after being sick. Well, I picked up an Apple //e, nothing special about that except it had LOTS of boards installed. Most //e I find have the 64K/80 col card and the disk controller and that's it. One of these cards has me stumped. It looks like it may be a modem but I have no idea where the phone connection might be. Well, I have a small idea. It is a two board set up with a good sized daughter board connected to the main card. The daughter board is label with Microcom. That and the speaker and the note about FCC Ringer Equivalence lead me to think modem. There are 16 dip switchs along the top of the main card. I'll take a picture and place it on my site tomorrow. If anyone could ID it and maybe help with doc or software I'd appriciate it. This same system also had an AE Z-80 Plus card. Anyone have the version of CP/M for that? Or doc? And finally, there was a PCPI APPLI-CARD. This appears to be another CP/M card. It contains a Z-80B and it's own bank of memory. Anyone have info it and the CP/M for it too? Never heard of two Z-80 cards in one system. Thanks. ----- David Williams - Computer Packrat dlw(a)trailingedge.com http://www.trailingedge.com

Thrift store finds

by Bob.Withers＠MCI.com

Phil, The stock SE was a 68000 with 800K floppy, 1MB RAM and a 20MB hard drive. I believe they were expandable on the mother board to 4MB by replacing the 4 256K SIMMs with 4 1Meg SIMMs (30 pin). There was also a SE30 which had a 1.44Meg floppy and a 68030 CPU.
