Ten or 15 years ago, Bottom Line Industries sold Pertec drives and parts, but they may be out of business now. Even then, I think they were asking ~$500 for...
... I've found them so far for $199 to $595 to $1200. (1200 being new in box) What is a drive worth to you guys? Its going to be about $899 - $1299 if I...
... Funny that you mentioned this today. I was daydreaming about whether it would be easy to build a bit-banging MMC interface with my 3P+S card. I know: no...
... One of my projects that I'm putting on hold is making a SD disk drive emulator card. It makes the SD card look like an Altair disk drive. Without...
Another source of Pertec drives is old (1975~1985) Jacquard business systems. Their Pertec 8" drives could be used after changing a few ...
... Makes sense. I assume that the issue is that Altair software did not separate the driver functionality the way CP/M did with its BIOS. Too bad. The only...
... I have 64k of RAM but I have to turn off 16K off it to leave address space for the Byte Saver. Lots of RAM is useful because of the way that my software...
BIOS? What's BIOS? Altair BASIC didn't have a configurable BIOS like CPM had. Drivers couldn't be loaded either. All you could do was try to hack the BASIC...

Hello enthusiasts! As a former employee of MITS in 1975 I have a continuing interest in the preservation of ALTAIR history. At present, my main concern is...
In a message dated 11/18/2007 8:21:24 PM Eastern Standard Time, ... Maybe you can help me...I'm still waiting for my 4K memory card ... no one seems to be...
That 4k card was a dynamic memory card, setup with a much too long refresh interval. In addition, it used a CPU interrupt when refresh occurred! You are...
In a message dated 11/19/2007 10:31:49 AM Eastern Standard Time, ... Oh really? I heard that they're coming out with a 16K card, but what would I do with so...
If we can teach Yates how to read the dynamic memory spec sheet we may have just gobs and gobs of memory for the Altair! On that older 4k card, the fix is to...
Glad there's a fix - thank you! (and welcome to the group) Jack ... From: altaircomputerclub@yahoogroups.com [mailto:altaircomputerclub@yahoogroups.com] On...
The original Altair circuitry was designed by people with very limited experience in TTL methodology. Many of the designers were right out of school or still...
Feel amused... I was one of the very earliest adoptors. I got the copy of Popular electronics and immediately dropped the plans for a 8008 based system using...
Nice work Steve! All but about 14 of the crew are now identified. Now if we can get the list displayed in the NM museum near the large photo it would be a...
It will take awhile, but I think we'll eventually get most of the names. If you know any other former MITSers, ask them to take a look at that web page. Steve...
Nope. Skeeter/riatla lives in Albuquerque, but never worked for MITS and only knows a few of their employees. He sure comes up with a lot of their products,...
Is there any way to get an idea of prices for altair equipment, hardware, and documentation other than looking at what has sold on ebay? I have some stuff I...

Bill, I'll work on making a MITS item inventory. I have only found one box of the Altair stuff I have. It is all Altair 680 related as far as I know. I...
