Hi - I was wondering if anyone in this group had an idea of how many more or less *working* Altair computers there are in the world today. Perhaps this is an...
I've got a working 8800 with a floppy (works most of the time) and a working 8800BT with a couple of floppies. I have another 8800 in near-working condition...
I have 5 working Altairs (that is, if I took them out of storage they SHOULD work). 8800 8800b 8800bT Attache 680b and several others that could be made to...
... I have a working 8800 original with two add-on 8 inch diskette drives and the original two-board diskette controller, two serial boards, either of which I...
Thanks for the responses. What I was really asking however is "..does anyone know how many *working* Altairs there are total, worldwide? 200? 1000? I ...
I think we all realized what you were asking but decided to answer the easier question that you didn't ask. . . ;) If I had to guess, and it would only be a...
well, as long as everyone is chiming in... i have an 8800B that was working the last time i fired it up. 56K RAM, 8K PROM board, two original hard-sectored 8"...
... That number may actually be high if you count only the ones that boot from floppies. Hard to tell for sure, but from the lack of them on eBay (except for...
Dave- It's great that you still have the Altair that you built. That's a keeper. I built an 8800b from a kit, and I still have it too. I now wonder how I...
by Dave Bursky (1980). I don't know how this one slipped past me, but I hadn't heard of the book until recently, on another forum. It usually goes for $40 or ...
steve, i think the biggest niggly little gremlin i had was the original clock circuitry. when the first load came out of the factory, the clock circuit was...
Those early Altairs had all kinds of timing problems. Thankfully, the model B referenced everthing to the system clock and most of those bugs disappeared....
it's the right company, but the wrong box. it looks like an early model compared to the one i've got sitting here. one of these days i'll dig the box out and...
... Not on a bet, only some of the worst bugs. I have one of the earliest ones. Powersupply was too weak to support 16k of S4K ram and IO, CPU clock plain...
Allison Parent- I have had much better luck with the 8800 than you had. I still own an original 8800 that I bought at a MITS surplus sale whien they were ...
I have an original 8800 also that I built up from parts assembled in 2004-2005. The biggest problem I have is the unreliability of the diskette board pair. ...
Craig, I can't recall ever having a temperature reactive "cap" issue, they tend to either work, or not. But the clock circuits and timing issues can certainly...
... Thanks, Bob! All good suggestions. I should have done these tests already, but haven't. I've also been bitten years ago by chips with a heat problem....
Andy- The 8800 had 4-slot mother boards, and you could daisy chain 4 of them to give you a total of 16 slots (16 S-100 sockets). The 8800A had a single...
inline comments... ... Mine was ordered December of 1974, when Poptronics het the box I was there. It was very low (xxx200) serial number. Nearly all the...
Did any of our members attend the World Altair Computer Convention (WACC) in Albuquerque thirty years ago? What recollections do you have? For our younger...
Steve; I was there. I was not an ALTAIR dealer, but my store, The Data Domain had been opened for over two months and I wanted to meet as many people from the...
MITS took over most of the main floor, but I remember that many other vendors were there too. One company (was it Micropolis?) displayed their high-speed...
No, I didn't. I wonder why they didn't just change one letter? Oh---Sorry, but I couldn't resist! Steve, did I ever tell you the story of the three guys that...
