New Altair Resurrection Tools!
- I have an Altair 8800 with a disk drive, but only basic boot disks. I
really wanted to run CP/M.
I wrote a disk image tool for Windows that will both read and write
disks from the altair. Now I have my own boot disk. I decided this
tool could be useful to other people, so I polished it a little.
Then I figured that a lot of people might have a disk drive but no
basic boot disks. So I made a bootstrap tool.
Using a program similar to the cassette/paper tape loaders I am able
to copy Disk Extended Basic 5.0 into the Altair over the serial port
in about 30 seconds. After copying the memory size prompt comes up.
At that point you click another button and a basic program is dumped
into memory. That basic program is a "server" program to give windows
access to the raw sectors on the Altair. 12 minutes later and you can
have a complete 330k disk read/written.
Does anyone here think they would like to try out these programs?
Anyone here have an Altair but no bootdisks? The bootstrap tool can
be used to boot any Altair into basic, even if you don't have a disk
drive. It will work with any version of basic.
- Hi Grant,
I'm a newbie to the Altair, but have my machine up
and running. I have a floppy drive, but only
blank disks, so I haven't been able to boot from
I have been working on my own personal challenge
to get my floppy emulator device (www.theSVD.com)
to boot the Altair without ever having a REAL
floppy disk. A crazy concept, but fun. I'm
making quite a few guesses as to the format of the
floppy, though the Altair manuals, schematics, and
firmware have enough info to get it done.
I have prototyped the Altair/PC-Floppy interface
adapter, and it appears to work...at least all of
the lines wiggle as they are supposed to. So now
it is a software exercise to get the right data
to the hardware to get it to boot.
I'd love to try out your transfer programs, it may
help me get things up and running.
PS - I just noticed that you put an inquiry about the
SVD to the web-site! Are you interested only in the
Altair support? (which doesn't yet exist :-) ) You
could be a "beta" site for me...
You may want to check out the disks I have with the Altair32 Emulator. They might be of some use to your efforts. What I’d love to see is a generic floppy emulator I can use with my IMSAI. Like I’ve said to various people, I hate 8” floppy drives.

I have a copy of Bascom's CP/M 2.2 for the Altair. It works with
Altair's hard-sectored floppy's,the 2-board floppy controller,
and boots properly with the SIO 2 board. If you like, I can
make a dupe of this disk and snail mail it to you.
