Hi,
I use to run this combo with RL02 drives,
it should fit on one RL01 drive but not much
free space left over.
This was in 1981-1982, someone else setup the hardware so I
don't remember much about that, I was working on the software.
I was surprised that so much of the operating system was
implemented in BASIC :-)

Another year and another missed Hamvention. Did anyone go? How was it? What
did you pick up?

Friday weather was pretty good. Classic computer-wise I picked up
a Heathkit ET-3400 with the Memory I/O expansion, along with all
the manuals. Got a Heathkit EPROM programmer with one module
(I saw the other one that Roger mentioned but thought it was too
expensive). From the same seller I also got a Tandy Color Computer
EDTASM cartridge and a 16K memory module for a Timex-Sinclair.
I bought a Micro PDP-11 and borrowed the seller's hand-truck to
get it out to my car. Right now it's in my garage -- I have no
documentation and haven't had time yet to check it out.
I bought four BCC52x single-board computers, with manuals and
interface documentation. These use the 8052 BASIC language
processor discussed on this list recently.
I hefted a Heathkit H-47 eight-inch drive housing (no drives) back
to the car. Quite heavy.
I bought a TRS-80 Pocket Computer in a case with a photocopied
manual, along with two handheld electronic games (Tandy Cycle Race
and Tandy Championship Baseball).
Also picked up an HP-35 calculator and AC adapter. Later I bought
an HP-41C and 82104A card reader, both in the original boxes with
all the manuals, along with an HP-28 and manuals. I also bought a
whole bunch of Texas Instruments calculator repair parts, which
happened to include a few TIL-311 LED displays.
I met fellow list-member Dan Cohoe, who had a truck full of HP
equipment (mostly 64000 stuff). Very nice guy, except that he's
taking all the old HP gear up to Canada! :-)
Saturday was mostly rain, but I did get a Hayes Micromodem II
card for the Apple, as well as some non-computer test equipment
and manuals. Sellers were motivated to drop prices since there were
few buyers out and many of them decided to leave early.
Sunday was much better, weather-wise. I bought two HP 5036A
microprocessor learning systems (the ones in the Samsonite cases).
I got an HP-85 and a number of boxed ROM module accessories
from an ex-HP employee, as well as some interfaces
(HP-IB
and serial). He also gave an an HP NetBeamIR box that provides
network connectivity via infrared links.
One popular sport on Sunday is trashbin scrounging. Sellers will
throw out or leave behind equipment and parts that they weren't
able to sell, so many folks make the rounds searching through
trash piles. I managed to find a new-in-the-box AOR WX-2000
weather fax receiver, some Apple II cards (nothing too exciting,
just serial and disk interfaces), an ATI 3D Rage video card, an
AMD AM2960 evaluation kit from 1984, and a complete Laplink
package with cables, manuals and software.
As others have said, the amount of classic computer equipment at
Dayton seems to be dwindling year by year. Occasionally there are
interesting items (the Micro PDP-11, for instance), but you have to
dig to find them.
This posting is probably too long already, but I'll be happy to provide
more details off-line for anyone who's interested.
Cheers,
Dan

I think it depends on how good you are at looking or perhaps what you're
interested in looking for. Your report varies greatly from the other
report that got posted. Your report makes it seem like the Dayton
Hamvention is still a good place to vintage computer crap.

As Ethan, Joe, and others on this list have emphasized, you've got
to show up early to ham fests. The bulk of my purchases were on Friday
(the first day of the show) and mostly in the morning. I think Roger
arrived much later.
I have also made friends with some of the vendors, so by now they
know what I'm looking for and will hang on to things for me. (For
instance, that's how I got an early model of the HP 5036A with the
ROM in a ZIF socket last year and the HP Series 80 stuff this year.)
I guess my point is that the days of having lots of vintage DEC, DG
and other gear moving through Dayton are gone. The show itself is
also shrinking -- remember that it's mainly a ham radio event, and
the ranks of amateur radio operators are also shrinking. Attendance
these days isn't nearly what it was even a few years ago. Also,
a number of dealers have stopped coming and do much of their
selling on-line. The weather forecast didn't help this year, either.
Your report makes it seem like the Dayton
Hamvention is still a good place to vintage computer crap.
Obviously the best way to build a great vintage computer collection
is to hook up with an electronic recycling organization in a
technology-driven part of the country. :-)

It's not electrically RX01 compatible, but with the card, it is
logically compatible (I have one at home that I was debugging when
I left).

He also comes down to Northern Ohio to raid for DEC equipment. We've
traded stuff before, when he comes through.

A very typical pattern. What gets hard is cruising the aisles when
everything is covered because it _might_ rain again.

Yup, there was a lot of that Saturday afternoon... once bitten, twice shy

I think some just left early to go to the bar... that's what I'd have done!

Yep, everything wrapped in plastic tarps makes it hard to see what's
available. But when you do find something, and the seller is still
there, he's usually willing to deal.

Ah... so you said. I can't recall what drives are in mine, but IIRC,
they are rather ordinary (for their day) 8" drives with a 50-pin
edge connector. There's plenty of smarts in that box (or at least
there _were_). OTOH, having a nice mounting spot for 8" drives with
the right PSU for the motors (24V, commonly) is handy, even if you
have to run the 50-pin cable to some CPU box somewhere.
What I can't recall is what systems besides the H-11 that box might
have worked with. I also don't know if the boards in the H-47 were
different for different hosts. I'm sure that information can be
found, though.
Back panel says it's an 11C23-F.
OK... an 11/23 with some amount of memory and disk. Given what I
remember of those days, I'd guess either an RD51 (10MB) or RD52 (30MB);
probably not an RD53 (73MB) or they'd have gotten a faster processor
at the same time, and probably not an RD50 (5MB), but it's possible.
Not sure about memory, but 1MB sounds like a good guess, based on
what cards were common in that day. It takes up to 4MB, but, again,
given costs, you'd more likely see an 11/53 or 11/73 with a full boat
than an 11/23.
Fun little system... it will run lots of stuff that doesn't require a
CPU with Split I&D space - RT-11, MicroRSX, 2.9BSD (with MSCP patches)
I'd recommend RT-11, but I'll be curious to hear what's on the disk.

Nice. I consider TIL-311s to be cheap if found for under $2 each. You
can still find them in abundance for $7-$15.

Finding someone is usually the trick at that point.

a Heathkit ET-3400 with the Memory I/O expansion, along with all

Sounds like you did very well Dan...but on the other hand, and I really
wasn't going to torment you with this but.....so did I.
By an incredible stroke of good fortune, about mid-afternoon Friday a
gentleman walked by, stopped to take a look and offered to buy all the old
HP monitors I had on the truck. On discussing my interest in HP 1000's, he
mentioned he had qite a few.
Later he returned to organize for meeting at the parking lot with the
monitors and announced that he'd part with all his 1000 items if I was
interested in going to his warehouse closer to Cleveland. Planning to head
home that evening anyway, I followed him for three hours to load my pick-up
with HP1000 items and ...about the nicest 2100A I've seen. All in trade for
another monochrome monitor and an untested 9153B.
I'm still in shock.
