Hello vintage computing fans across the country and around the globe
(that's right - we're international!) The 17th Vintage Computer
Festival Midwest is coming up in just two weeks! The hotel is sold out
(months ago!), the tables are all booked (and then some!), now all we
need is YOU!
View over 80 exhibits and vendors, witness more talks than we've ever
had before and observe in person the Fabulous VCFMW Auction!
And the show is FREE, to boot! All you need to do to participate and
receive the full benefit of retrocomputing in the Midwest is...show
up.
Find out more at vcfmw.org!
[September 10-11, 2022 in Elmhurst, IL, right outside of Chicago]

I will be at the VCFMW both days. I am bringing a bunch of
stuff to sell. I have a big box of Q-bus boards from my
Micro-VAX II system. I also have two ESDI disks that have
VMS 4.7 on them, and an Emulex QD21 controller. I'm hoping
somebody at the Fest can image the disk that was last used.
I also have a Nat Semi 16032 system that I cloned back about
1982. This was built on the Multibus I bus. Unfortunately
I overwrote the disk with VMS when I set up my VAX.
I also have a whole bunch of Nat Semi 16032 development
boards from a multiprocessor project (Multibus I).
I also have a Multibus I ADC board from Data Translation.
I also have a Nat Semi 8500 graphics demo board.
And, not for sale, I will be showing a Honeywell Alert
airborne CPU that was developed in 1965 for the X-15
project, to help get the pilot back to Edwards AFB with the
right energy to land in one shot.
It was the first all IC computer delivered. (The Apollo
Guidance Computer project started first, but due to the
complex software, it was delivered a bit later.)

UGH, I must have DREAMT I had the QD21 that I had used
before on these disks. I can't find it now, but I DID find
a Dilog DQ696. I don't know if they use the same sector format.

If I tell you that they are not, will you think I am just trying to get
the QD21 from you? I need one to replace the Sigma ESDI controller that
failed, and no its format is not the same either.
They also had a choice of hard vs soft sectoring. I believe Emulex and
Dilog handled the RCT differently on the disk too.
Let me know if you are willing to part with the QD21.
cheers,

Sorry, going through emails from 2012, it seems I sold the
QD21 for a song back then.
Wow, really crazy when you don't know what you dreamed and
what you really did! But, I sure can't put my hands on it now!
Jon
2:34 p.m.
So now, like me, you are stuck with a bunch of ESDI drives and no
controller!
I do have one DQ696, on my MVII in a BA123 box, but the other controller
was a Sigma that developed in internal faulure and which I used for RT11
on my 11/73 BA23 box.
Now I have to share the one controller between the two boxes. RT11 one
day and NetBSD another!
Like you, I sold all sorts of stuff for a song, including a
millivolt-on-HVAC common mode DT2765 a/d card that was $3000 when new! I
also had 3 KA630s and accidentally sold two, so now I do not have a
spare for the microvax either!
If anybody out there has a DQ696 or an RQDX3 available, I'd like to hear
from you!
cheers,
Nigel

I DO have a DQ696 that I will be bringing to the VCFMW. If
it won't read my ESDI drives formatted on an Emulex QD21,
then it is of no use to me.

I have a spare RQDX3, but I really recommend finding an ESDI controller.
It is literally a slug compared to my MTI ESDI controller.

I agree, but in addition to getting the main system disk back up, I have
an ST506 emulator from David Gesswein that I would like to get working
after I built it. My Plessey DCV54 does not even offer a drive select
signal!

Oh those things are so fun. Let me know off list, I'll start checking
through things to find it.
