Yes, I have read that Gordon Letwin worked at Heath before coming to
Microsoft. He worked on OS/2 and Windows.

Subject: Heathkit HDOS source listings
Hello all,
I recently acquired a 4-volume set of Heathkit HDOS source listings.
They are in assembly langage, printed out on May 16th, 1980. They
have nicely printed cover pages from Heathkit, and the rest appear to
be photocopies of greenbar paper listings. I haven't examined them
completely, but they appear to be intact, readable, and complete. The
command processor and BASIC interpreter are definitely there, and
there is a lot more as well...
I'll post more details if anyone is interested. Also, I don't know if
these are archived anywhere. If not, is there interest in getting
these scanned and posted? If so, I'll move it to the top of the list.
Bear in mind it's at least a 6" high stack, double-side printed, so
"top of the stack" may still take a while to do... :-)
I found some comments by a "J.G. Letwin". Perchance the same Letwin
of OS/2 fame?
Thanks,
Rich B.

Sergio, and Jay, and all others,
Thanks!
SYSPROG did it. No password ... I think this was a "personal use
only" system, so no surprise at the lack of password.
I did some more targetted Google-ing and found a PDF book on Pick
BASIC, so I guess I'm on my way :-)
One concern is that I did NOT get any install disks or docs, and the
hard drive this is on is an ancient one, making funny noises....
Hopefully it'll last a little while....
Thanks all for the help!

Hi
As you get these images, always ask what controller
is being used for the disk and what I/O card is used
for the console. Many of the early machines OEM'd these
parts of the system and the boot image for one machine
may work for another. It would be great to also
index by these parameters as well.
I just thought, get the RAM size as well. It is good
to know if it is a 32K to 64K system. Can others think
of what else should be kept track of?

Hi
For glossy surfaces, I've had some luck using Goof Off.
It seems to soak into the plastic and remove some stains.
I rub it, not soak it.
Dwight
it took a while to grind through all of the scans. looks like I
actually DON'T have the ones you have. I have 78-80 (about 900
pages) and early ones (pre '74)

Just saw the msg. I should have them scanned, will try to get them on
line this
morning, along with the schems for the 8/A semiconductor memory
Sun-labeled ones are what you should watch for.
They all seem to have the 800bpi option, and are SE SCSI.

Spotted one over at Weird Stuff for $50 today.
Sun PN 596-1219
The 800bpi option (replacement R/W board) PCB
part number is 07980-66531

I visited Thom today and he gave me a stack of these. They're short news
letters that list PDP-8 related issues such as software releases, bug
reports, training classes etc. The ones that I have cover the years 176
through 1978. Are these already on-line somewhere or does someone what to
scan them and post them? They're short, only about ten pages each.
Joe
