Speaking of PDP-8 music: there was also a music program for the HP 21xx 
computers. There are only absolute binary papertape images available. Does 
someone happen to have the source listing or program documentation for 
that? This music program plays on a MW radio just like the PDP-8 MUSIC 
program, but it plays only two notes a time. It runs well on our 2116B and 
2100S.

No but RICM as a PDP12or two.  Worth contacting them and all.  They
might like a copy of the
tapes if they don't already have them.

Do you have any information on the AA01-A DAC that was used with the
PDP-12? I see in the PDP-12 System Reference Manual that it is capable of
supporting three channels, 12 bits each. It gives an example of one
instruction, 6551, which loads the first DAC. Is it safe to assume that
6552 and 6554 are the other instructions to load the other two DACs?

I see the AA50-A in the 1972 PDP-8 Small Computer Handbook has sequential
instructions for updating the DAC channels (up to 8).

AA05-A/AA07 use a more complex address/data method to address more total
channels, but that is listed in the Laboratory Computer Handbook as an
option on the Negibus.

I don't think this album has been forgotten; I have a copy, and I know
others with copies, too. It seems as though "Unplayed by Human Hands" (both
versions) are less well-known. I would like to work on getting the original
software archived, assuming it's still out there, as it ran on a Straight-8.

Those were likely with a PDP12 or LAB-8 with DAC board.  The code
actually is a roughly
digital version of tones in 10 or 12 bit form by writing sequential
words (waveforms) to
the DAC.  Before that it was done setting link and clearing link bit
with a timing routine.

There was a version of that also for MINC-11 and I've see variant back
when that used multiple
DAC cards for stereo or multiple voices.

It was also a thing for the S100 8080/z80 set (using a DAC) and many
other systems
(Kim-1, Apple, Cosmac, Commodore).

Of course everyone here forgets the First Philadelphia Computer Music
Festival on vinyl from '78
with samples of computer played music.  I run my copy on occasion just
to remember being there.

The recordings, or the software? If you're referring to the latter, please
send a link! I know someone has a GitHub repository, but it's missing any

Bill, which of these tapes do you have exactly?

I've checked and it would appear DECUS 8-152 is not intended to play over
the radio, but rather with a DAC (or two). I'm still working on fully
understanding it, but that's my conclusion thus far.

Thanks,

Kyle

Vince has a listing for some version of DECUS 8-152 on his website (
http://svn.so-much-stuff.com/svn/trunk/pdp8/src/decus/8-152/decus-8-152-lst.pdf).
I have reverse engineered it enough to have his version play a few songs.
However, it seems like there's a difference between the music tapes I have
and the listing he has.

I don't know what hardware was required of this software, but I suspect it
to be a DAC responding on address 055. This seems to match with an AA01
option.

Did you end up buying these tapes? I have digitized the music tapes I
bought from the seller and will post them soon. It would be excellent if
the buyer of this lot would do the same.

Musically,

Kyle
