This looks like it was an especially good deal. I recently looked-up what I paid for mine few years ago...$3,302. Does anyone see any flaw with this unit? (I...
It looks like a nice clean unit - don't know if the unidentified boards are MITS, which could make a difference. I also like the fact the builder sprayed the...
I recently decided to sell my Altair. I would have loved to get it working again but just don't have the time, plus I will be moving to a smaller house and...
You're going to have two problems shipping the HD. First, you'll want to crate it to ensure that it arrives safely. Second, you need to find a freight company...
I just looked at your auction (ebay#2784770538), but you don't have pictures of the hard drive, so it's difficult to know what you have. Usually, Altairs were...
Two pictures of the hard drive are in the composite pictures. Its the big box with the interface board sitting on top of it, the second picture is of the...
Ok, I thought that was the rear view of a floppy drive. Well, it's obviously a Shugart and not a Pertec unit. How do you interface the HD controller to the...
... up ... Hi TMollerup, It is a pretty good price. Probably cause the seller had it in the wrong category....I notice it was a first time seller...they would...
Liquidcrystal1, We have similar disorders. My records show these prices for the 8800 boxes sold on ebay since Feb 2, 2003. I don't think any others got past...
There's an 8800 currently listed on ebay. It's item #2787909763 at http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2787909763 . It's the same computer that...
As a former MITS Engineer before and during "The Time" I was asked to host a "Legacy Computer Day" at one of the NMCS semi-annual general meetings, and I...
Thanks for posting the link to the NMCS photos, Ron. That presentation was a lot of fun. We should do it again some day. Ron is new to this group, but not to...
Hello, I'm the proud owner of a MITS Altair 8800 serial# 222027K acquired sometime in 2003. I got it from a music store in Mountain View, CA. The computer was...
Thanks for posting the pictures. Your computer looks pretty clean. Was the music store using it for anything other than a blinky-light window dressing? Have...
Thx Steve. Exactly, window dressing! I try to run the small addition program from the manual, but as I said in my first post, whatever I deposit in a memory...
... Jerome In my experience, the most likely causes of this kind of behavior are: 1) a bad memory chip 2) a bad buffer chip The only way to tell for sure is to...
Which store in Mountain View was it? I work off of Castro and would be curious if I'd ever passed it and missed the old box. I've seen similar memory issues...
Jerome, Your guess about it being a tape interface makes sense to me. One of the quirks of Yahoo is that only the person who posted a photo and the group...
I've made many changes to the Virtual Altair Museum and added many scans of MITS photos and documents. Feedback is welcome. The site currently uses HTML frames...
just purchased a "new" Altair 8800 (no, not the "a", not the "b", but the original). Power was a problem, but after replacing every electrolytic capacitor on...

There are two "+5 Volt" sources. Depending on which schematic you look at, they're also labeled as being +8 or +9 volts, too. In this case, the labels are...
You're a saint. I was wondering whether this was a Power Supply issue or one of the components after the supply. I would not have guessed the transistor. I...
Hopefully the E, B and C designations on the circuit board for Q1 are correct. If so, checks out. Not short between E and C. There is some current flow...
You should see infinite resistance between base-emitter and base- collector if your meter's negative lead is connected to the base. If the + lead is connected...
Altair Computer Club group members, Our group has been hit by quite a few spam messages lately. The latest one, from "Yolanda_wy9o", went so far as to instruct...
