I acquired my Altair 8800 (along with an 8800a) shortly after starting this site and decided to document its arrival and "restoration" a bit.
The machines came via UPS and, predictably, got bounced around quite a bit in transit. It's a shame the UPS folks missed all of those red "fragile" labels all over the boxes. Then again, it's obvious why they prefer the color brown... Fortunately, everything was double boxed and survived pretty well.
I had purchased these computers based upon a few grainy pictures so I wasn't quite sure what to expect. Once I unboxed the units I was able to assess what they really looked like. The machine was definitely used, but it wasn't beat up so badly that it wasn't reparable. Some of the dents and scratches in the case are permanent, but the basics look pretty good.
The interior was dusty and somewhat rusty (around the transformers), but basically sound as well. This unit had a RAM card bouncing around free from shipment. I re-slotted it before snapping this shot.
The cards actually showed the most wear and tear in this system. The CPU card shows signs of having been inserted and removed A LOT. It also seems that a previous owner used pliers on the corners of the cards to get them out. They still work, however, which is the most important part. This Rev 0 CPU card has the especially rare Intel 8080 chip. Most Altairs were powered by the Intel 8080A
The Altair Disk subsystem consisted of two boards and the disk drive. Here is the first of those boards.
This is the second of the Altair disk boards. The connector on the first one hooks up to this one and then the cable hooks up to the remaining pins on both boards.
The MITS SIO-2 (2 serial ports) board was a mainstay of Altair systems, connecting them with terminals, teletypes and all sorts of other peripherals. This machine had one installed and had the hardware to activate both ports.
The 2k/4k EPROM board used in both of my Altair systems came from the Solid State Music company. 1702a EPROMS were used to store the boot loader for the disks and potentially paper tape or cassette tape.
The Altair 8800 came with 32k of RAM on 4 Seals Electronics 8k Static RAM cards. It seems to run properly with these, but I can't imagine that the power supply supported this much draw.
After removing the cards and then removing the chassis from the case you can get a good feel for how these Altair's were built.
A look inside reveals the power supply and the 4 slot motherboards chained together. This machine was built from a kit. In many places it shows.
After carefully cleaning the chassis, checking the wiring and re-soldering a few wires that had come loose I applied power to the machine for the first time. There was no smoke or burning! Eventually I added all of the cards back in, one at a time, to see if they were operable. There were no nasty surprises throughout this operation.
Once the machine was in order I pulled out one of the disk drives to see what would happen. I inspected the unit, but didn't dismantle it or clean it all that thoroughly. It too powered nicely and without smoke or flames. Sadly, I don't yet have the expertise to get the machine and the drive to talk to each other.
Here's the drive with the cover removed showing the Altair disk controller board and the beefy Pertec disk drive.
The original owner of the Altairs in my collection came across some additional documentation after a move. Included were the manuals for the disk drives, the 8800a and almost all of the S-100 cards supplied with the machines!
One of these days I need to rebuild this site. As a prelude I'm starting to practice taking pictures. The following, while not yet all that good, are far better then the bulk of the photographs on this site ... for now.
By request I've put up three new pictures. These are of the bare MITS 4 slot motherboards as originally shipped with the Altair computers (both top and bottom) and of the Altair front panel. Each of the following thumbnails links to a MUCH bigger picture (about 4 MB for the boards, about 5 for the front panel) so beware of the wait if you click on one!
The two images above link to 300 DPI scans of the Altair 4 slot motherboards. The rev 0 and rev 1 boards are both pictured. The top (connector side) and bottom (solder side) of the boards was scanned to facilitate reproduction.
If anyone does use these scans to reproduce either of these boards, please let me know. I'm pretty sure I'd be interested in some.
The thumbnail above links to a 300DPI scan of an Altair 8800 front panel. There are a few nicks and scratches on it, but the condition is exceptional considering the age of the machine. The scan gets a little fuzzy at the center because I couldn't lay the plate perfectly flat on my scanner. It's pretty good, though.
The scan should be of sufficient quality to reproduce an Altair front panel accurately. If you use it for that, please let me know. I'd be interested in cleaned up ones for some display units.
If you've found any of the above scans useful, please let me know!
I've recently acquired a handfull of early paper tapes for the Altair. These contain an Assembler, Editor, Monitor, BASIC, boot loaders and more. I'm hoping to get these read in to a machine and dumped to disk so I can reproduce them here. As soon as I find the time. . .

you need to replace the power supply capacitors (the large silver ones) for the continued health of the Altair - if you cannot find the exact capacitors it had originally, there are companies that can take your old ones and rebuilt them with new smaller ones inside the old capacitors' casings to preserve the original look - but don't put it off or you could lose a lot

PS PS PS.. if you hook the video board up to a vcr let me know one of the dip switches makes the video inverse white on black its cool if i keep looking mabie ill spot the card w video out and could tell you witch one it is then you would have video remember in those days it was composite video same as video in on vcr..

Just wanted to post a little update about my Altair; the short of it is I still have it, but I have yet to find time to work on it. I have managed to find a few more cards as well as S-100 bus edge connectors; I also recently got some cards (including a bare 6502 cpu card - just needs to be populated), as well as some prototyping cards for the S-100 bus. Plus some 8 floppies. I hope someday to get around to restoring this machine (I know its been 5 years since I last said this - haha!).

I have an original Altari 8800(SN#xxx19) that I build when it first came out. It has an original CPU card, but I upgraded the 8080 to the A version when it first came out. Mine was the first issue card, so it has the clock mods needed to make it work. The box was heavily used as a working computer from 1975 to 1979, and served as the prototype for a fully functional home computer. The power supply was moded when it was first built to provide full UPS functions with separate gell cell packs for each of the power rails. It has a TV-Typewriter board mounted onto the lid, custom boot prom on a ByteSaver board, a 32K dram board and a complete MITS dual 8 inch drive box. I would like to sell it, and am posting this here before I list it on ebay. Please contact me for photos or any other information.

I authored the assembler sold with these system back in 1974/75. I was just going through my old coding notes and manuals. Donated all the hardware to San Diego computer museum in 2000 and it closed a couple of years later. I enjoyed seeing that people still have interest in this history and even want to make them run again. I'm a full time RV'er and travel the country so would enjoy visiting with someone that has a working system. It might be best to call me at 909-260-8987 and mention the ALTAIR as email can get lost if I don't find it in junk mail before its deleted.

This is a cool computer. You said that you were having a little trouble getting the floppy drive and the altair to communicate with eachother. I have been working on electronics for a long time. Maybe I can help. Just send me pictures of all of the parts of the circuits in the computer and the floppy drive (Moving the metal cover if you have to will be helpful) including close ups where I can clearly see the number on the integrated circuits and the conductors. Right side up and upside down and I will draw a schematic and all the connections you should use. Oh and also send me a picture of the back of the computer and the floppy drive assembled.

About 1977 or 78 , I bought an Altair 8800b, which I had for quite a few years, one day a solder bridge came loose and I think shorted the +12 volt line to the + 5 volt line. needless to say It quite working. that was about 1981 or so, I tried to fix it, but ended up tearing up most of the boards, trying to take the Ic's out. Since then I have used sockets on all my boards. I don't have any of it anymore, it got lost and trashed and given away after that. I am currently trying to WireWrap up a CPU Board and make one, using schematics that I have gotten off of the internet. I also have a North Star/IMSAI with a Z80 CPU Board and many CPM 8 Floppies, which still works, But I would like to build my own Altair, I am half way through the WireWrapping of the CPU Board, and then can try it in the IMSAI.

Teletype machines, paper tape, boot loaders, ADM-3 video monitors, daisywheel printers (45 characters per minute and ) $1,000 each), 110 baud modems that you pressed the phone handset into; eventually 5 1/4 and then 8 floppy diskettes that you had to remember to mount and unmount or you would mess up the directory to your files! Oh my, those were the days. I soldered many boards � CPU's, memory, interfaces. I was always amazed when they actually worked. I've often wondered what our terrific technician, Dave, is doing now.

One day I did a literal translation of Altair basic into ascii characters and one section of the code came across with Bill Gates name in it as the author.

This is the best feature on the Altair I have seen. Thanks for the look inside. My first PC was a Commodore Plus4, that I taught myself BASIC on. Today I build my own PC's and use the Linux OS.

Eric & I, both had Mr. Scott as our teacher in electronics. 1975, what a year, my first computer, my first wet dream. Since I had been programming a 4004 over in the Math department, Scott recruited me to come in an hour early before school and toggle in the boot program for his Altair. At least Scott didn't spray paint the computer flourescent green like the rest of his equiptment. I remember the day Scott came in holding up the punched tape of Microsoft Basic he illegally copied from a friend. He thought we would be interested, but it just collected dust on the shelf.

This was actually the first computer (type) that I used. It was during sophomore year in high school (Mira Costa High in Manhattan Beach, CA). It was in 1975. Our electronics teacher said he bought this instead of a VW he was eyeing at the time. It had tape drive, and no boot loader. You hand entered the Boot Code, to get the boot ready for the cassette tape, this loaded a BASIC Interpreter. If the boot went correct, and the tape loaded, you got an OK on the monitor. We typed programs into it. One fun one was a paper tape punch. You would type in a name, word or phrase, and it would print out on paper tape. This started my life long love of computers. My next one was a BENDIX G-15 with DRUM Memory...Before Vic-20, C-64 and PC's. I am not a network admin. Great fun. Thanks for bring back good memories!!!

I am amazed to see that people actually try to
make money off 'my' Altair 8800. Not exactly the
spirit when I used it. We tried to open up the
world for you, and succeeded. And now you
commercialize it like everything else you touch..
Yeah yeah I know.. Going to get my coffee now ;-)

I have recently purchased an Altair 8800 for $100.00 from an electronics junkyard here in Phoenix. It is in what appears to be OK condition, although it is really dirty. It is missing its top cover (if anyone can tell me how I might get this replaced, and whether it would affect value, I would be interested). I am afraid to power it up in the condition it is in. I plan to clean it up, and check the power supply and other areas thoroughly before doing so. It has what appears to be the Z80 card, 4 16K cards, a parallel/serial port card (no cables, though), and a drive controller card. The front panel is in great condition. If anyone can point me to further help on this machine, it would be helpful to say the least. I am scouring google in the meantime. Thank you!

I have never seen an Altair sell for $10,000 -
even in Canadian dollars!
I have seen a few break $3,000 for complete,
clean systems but most tend to fall within the
$1,000 to $2,500 range.
Depending on your tax receipt you may or may not
be in better shape donating it.

Hi. I have an original Altair 8800 that works, or did the last time i turned it on. The local museum curator has offered me some kinda tax receipt for it, but when i see numbers like $10,000 i think it might be better to sell it :)

For those seeking an Altair I'd suggest places
such as eBay and the Vintage Computer Marketplace
(marketplace.vintage.org) for a quick buy.
Posting here is certainly good and you may get a
response directly or because I repost many of
these requests to the Computer Collector
Newsletter (http://news.computercollector.com)
Best of luck!

That machine looks great! I'm going to get an Altair 8800 too when I grow up. All you need to do now is to connect the Monitor, the Keyboard, and the Mouse on your system. Since it's a really old computer, try loading MS-DOS on it, and see what happens.
