The 2109E boots from the HPDrive emulator running on a Windoze box,
pretending to be a 7925H. The OS is RTE-6/VM. The 2647A is connected as
the system console, and a second BACI is connected to COM2 on the PC and
the QCTerm terminal emulation software.

I should get setup with such an HPDrive emulator sometime. I probably
have all of the pieces I need on my 2117F, including an 12821A HPIB
CS/80 interface. Have you written up any notes on setting up the
HPDrive emulator and disk image for this particular RTE-6/VM usage?

Hi Mike,
I enjoyed meeting you at the VCF last weekend. I really liked your
2209E and 2467 terminal. It's a beautiful system, really. I'm sure you
talked to a ton of people, and can't remember everyone. You described
in some detail how you were finally able to remove the screen glass
cover, and get rid of the glue to remove the "screen rot". I was
interested because I have an HP9845A with the same affliction.
I wish I could have spent more time reading your posters and poking
around your hardware, but I didn't allot enough time at the exhibits
this year. Next year I will know better.
Just wanted to touch base, and congratulate you on a first rate exhibit.
Best regards,
Dave

As I recall, the 900 series had a different connectorthan the 50 pin that the 800's
had.Dwight

It is also not exactly the one millionth - I'm pretty sure the millionth
SA800 went to the Smithsonian and the next one is in the office of Dave
MacDougal, the owner of WeirdStuff, Sunnyvale CA,
http://www.weirdstuff.com/. Dave closed the doors of Shugart in 1985-6.
Maybe Shugart Corp. gave the one million minus one to Wang
One interesting anomaly is the SA900 series was early-on replaced by the
SA800 series, although Wang may have bought them into the 1980s. So the
SA901 label is probably a publicity stunt.

Naah. There are NOT THREE one-millionth of the same drive.
The eBay one is one-millionth SA901?
The Smithsonian one is one-millionth SA-800?
The Weird Stuff one is One-million-and-oneth? SA-800?

Who has the one-millionth SA850? (I'd rather have double-sided!)

Makes sense to me. People usually don't run serial numbers sequentially
across different models. The 1,000,000 SA601 would seem right by the label.

It could easily be the 1000000th 901. There would also be aone millionth 801, 802 as well
as 800.The 900's had the wider pins ( I think 44 but would have to look )The 800 used
the 50 pin.I wonder who determined which connector to use? What didthe original IBM
machines use? The Sugarts came with differentfront plates as well.I think the 50 pin got
determined by the use of ribbon cable.Much cheaper than hand wiring or special PC board.It
seems like the 8 inch drives had all kinds of connectors.I have a couple of other drive
connector and signal typesfrom different manufactures.They seemed to have settled down to
a standard by the5 1/5 drive time.Dwight

I am pretty sure that Shugart lumped the 900, 901 and 801 into one family
for counting purposes so that there would only be a single one millionth
drive of one model number from that family, and I am also pretty sure that
this was the first disk drive family to achieve 1 million units produced. I
doubt if the 900, 901 or 851 achieved one million in and of themselves; the
volume was in the 801.
BTW I am pretty sure the Smithsonian drive was gold plated.
BTW the whole concept of one millionth is fairly ambiguous given the
distinction between built, shipped, gross sales and net sales. I suspect
these were manufactured on a single day based upon lot sequence number and a
calculation of the date from gross prior sales and finished goods inventory.
It maybe they pulled finished goods and remanufactured them with the plated
castings.
To the best of my recollection the early FDDs used pin and socket connectors
such as the Ampex M series but went to flat ribbon cable for cost. By the
late 70s I think the 801 became standard and everyone offered a Shugart
interface compatible drive.
FWIW, I joined Shugart just after all this and have asked some of the more
senior alumni for comments
