I just acquired and fixed two Altairs (one 8800z and one 8800b) and have MITS 4K and 8K BASIC on tape. Problem is, I can't find any bootstrap loader for these programs. I have the simple cassette read program in the Altair manual, but that just gives me raw bytes. I suppose I could reverse engineer the tape format (I can read the tape fine) and write my own cassette boot loader, but I wondered if anyone out there could possibly lend a hand? Thanks,

Quote from 'Independance Day' (I love a good 'blow-things-up' movie!):
"That's not entirely accurate..." B^}
There was no conversion of digital to analog done in the DAA. Specifically
in the case of the Hayes for example, the (analog) audio modulation was
done in the cute orange blob on the board. The only digital signals coming
off the board drove the relay in the DAA box for acquiring the line and
pulse dialing. Beyond that, the DAA provided 'protection' and
coupling/limiting of the analog signals from the board to the phone line.

Yep...

I have had several older HP vectras here that have had HP-HPIL interfaces,
including an HP Vectra CS (8086) and a Vectra RS-20 (386). The HP-HPIL
interface was generally supplied as an 8-bit card that plugged directly
into the ISA bus.

Back in the 70's, there was an individual who sold indexes to the various computer magazines (in hard copy format, and perhaps on Disk). I bought it and have a copy of it somewhere, but there is very little chance that I could now find it.
The later issues, starting sometime in the 80's, are indexed in Computer Library, a $1,000 per year Ziff-Davis service on a monthly CD-ROM (in fact, not only are they indexed, but I believe that the text of the entire magazine is included in the service)(yes, I know that ZD is a competitor of McGraw Hill, which publishes Byte, but Computer Library has competing publications).
But this didn't start until the late 80's.

Oh boy. I've had a back-burner BYTE index project that I moved forward by
almost a millimeter last weekend. How far along are you on putting
together an index?
If you, or anybody else, wants to collaborate on a project like this,
there's already several thousand BYTE's that have been indexed in BibTex
format. I plan (OK, hope) to automate entry and searching of this and
similar indices. Currently the coverage of material of interest to this
group (like early BYTEs) is pretty thin.
Check out Nelson H. F. Beebe's web site for a sense of what's been done
so far:

Myself and another individual are trying to find the source of a magazine article which describes a modification to the IMSAI CP-A front panel.
The title of the article is "The Slow-Stepping Debugger" by Howard Bendrot.
We believe that it was published between 1976 and 1979, probably in 1977. We believe it is likely that it was published in Kilobaud Microcomputing magazine, and there is some suspicion that it may have been on Page 60. But none of this is confirmed, and we don't have these magazines to verify this.
Can anyone identify the Magazine, issue and page number of this article for certain ?
Thanks,
Barry Watzman
Tonight I finished posing the Altair 8800b manual. Enjoy!
The next thing on the plate is the Aim65 Users Manual, and then an index to
the Byte Magazines that I have. After that, probably a load of PDP-11
manuals.

i've found a web site where minix/ELKS can be obtained, but it was expected
for one to have a functioning linux system to download and create the disk
images. since i only have OS2/windont95 access, are there any other choices as
far as downloading a copy to install on an xt?
