>>Mendelsson's will probably have their large tent
with pallets of slightly-crushed UPSes, ammo cans and
other surplussy things.
Refresh my memory, does Mendelsson's have a
warehouse-like store in downtown Dayton, crammed full
of retired electronics (and office furniture) ? I
worked in Dayton many years ago and I remember
spending some interesting lunchtimes in this
warehouse-like store looking for goodies.
Of course the one thing no-one should miss when in
Dayton is - Marions' Pizza. Ask for it by name.

>>You going to be at all of the Hamvention or just
part of it?
Probably just stay for Friday. I am going to drive
over Thursday from PA. and be there promptly (I hope)
for the beginning. I went once before 7 or 8 years ago
but didn't really have time to take in all the flea
market. Seems a shame to miss out on the Sunday
dumpster dive and free 'stuff' but can't be helped.
I have already cleared out the back of the station
wagon in readiness for a large quantity of purchases.
I think I need to get one of those wheeled trolley
things you see people with at hamfests. I seem to
remember having to park at Wright-Patterson last time
and taking a bus in, so there'll be no running back to
the car after every purchase.

>When and where is the Hamvention?
Dayton, OH, and it's the weekend after next (Fri 16th
May through Sunday). The focus is ham radio equipment
but there was also a lot of computer gear and test
equipment last time I was there. As a ham as well as
a, er, whatever computer enthusiasts are called, it's
worth the drive for me !
Chris, thanks for the offer of help on the 68k apple
stuff. I didn't really have a specific model in mind.
I was just thinking wistfully about all those macs
stacked up at TCF and hoping they didn't get trashed.

When and where is the Hamvention? I'm assuming from the name it is mostly
Ham Radio stuff (something I'm not into), but since you guys seem to feel
there will be some classic computer stuff, I might take the drive
depending on time/date/location.

I went on Saturday but skipped Sunday. Definitely
worth the trip (120 miles R/T) although I didn't bring
a whole lot home. I ended up with handful of TK50 tape
cartridges (marked VMS5.4, but not sure if this is a
complete set) and a scsi zip drive to replace the one
I butchered 2 years ago. I passed on what appeared to
be a 9-track tape drive and a Wang printer. One vendor
was selling some VME components but other than that I
wasn't tempted this time around.
I wish I'd picked up one of the 68k Apples. I'm sure
the Hamvention will have scads of them though.
Regards,
Dave

Yowzers!
Sounds like there was FAR more to be had on Saturday than Sunday when I
went. I don't think I saw ANY Apple 2 stuff at all other than one guy
with a box of software and a Cricket speaker box. (of which I meant to
buy the stuff, but got side tracked answering a Mac question for my
brother and then further side tracked by things to look at... before I
knew it, I had walked away, and gone home and forgotten to buy the A2
items).
I also didn't really see too many items older than 68k Macs and a few
early Pentiums. I guess all that stuff sold off on Saturday.
Looks like next year I go on Saturday rather than Sunday.

Saturday was definitely the day to go.
People offered me some stuff for free, because they
were going to dumpster it. But I gave them a couple of
dollars (usually the first price).
Although last year, a guy sent me a TON of HP Laserjet
IIp/IIIp parts for the cost of shipping. Which helped
me fix a couple that I have here.
I passed on a Power 100 (Power Computing PM8100 Clone)
for $10.00. It was a logic board and I/O board in a
case and PS with an FDD. No HDD or CD-ROM (though I
have plenty of those..). But, I already have one. And
didn't want to lug another home, just to have it sit
in a corner. But, I was tempted.. LOL!
I couldn't pass up the IIgs, and considering I have a
unit that exactly duplicates it, perhaps I should
have...
But, it will make a nice gaming machine to give to
someone and I have a few good games for it.
And considering I still do the occasional maintenance
on an educational program I wrote in the 80's, it's
good to have a backup unit.
Some people do leave stuff home, and remember to bring
it back on Sunday though. So, early on Sunday you can
find some things that weren't available on Saturday.
And the last hour is the best time for dumpster
diving!
LOL!

Dwight:
I have a working N* Horizon system (dual drive, 56k RAM, monitor in
ROM) and would be happy to lend my testing services.
From time to time, I've wrestled with the same disk image
manipulation issues for the Altair32 emulator, i.e., manipulating the disk
image outside of the emulation environment itself. My conclusion was that
there's no substitute for using the original OS for maniuplating the images.
So, we developed several methods to move program files into and out of the
emulator by using some home-grown and CP/M-native utilities and the file
transfer functions of the terminal program on the PC.
I really want to do an external "image management" program but
haven't found a clean/easy way without essentially re-implementing portions
of the base OS.

Subject: Re: Northstar File Transfer from PC
Hi Marvin
Maybe this isn't exactly what you are looking for
but I'm currently working on some software to transfer
entire disk images through the serial port of a H89
to a PC. I have another friend checking out my first
version, now. I hope to do a similar things for the
N*'s as soon as I get one of these machines up and
running ( on my list of things to do ).
I suppose that once the image is on the PC, one can
modify the image to include any new files, one wants
and then transfer it back to the N*. It isn't a nice
direct method but my main intent is to get some way
to send disk images over the net and not specifically
individual files.
I haven't fiddled with the N* at all and don't
know a lot about it. The H89 has a simple monitor that
I use to hand enter a simple bootstrap program. With
this, I bring in the rest of the code to run the disk
drive. Does the N* have a ROM based monitor?
I also have a similar setup for my Poly88 but that is
setup for getting code into the Poly88 and tape from the PC.
I used this to create code to do the various tape
copying functions. I can read code from a cassette
tape, transfer it through the serial to the PC and
later feed it back through the serial to the Poly88
to write back onto tape. I use a similar bootstrapping
code to get things started, through the Poly's monitor.

Steve,
I am certainly interested in the docs and in the
drive. I would be able to drive up and pick them up
>from you - I'm assuming the drive will fit in the back
of a Volvo station wagon, does that sound feasible ?
If you want to contact me off-list we can arrange
something. Many thanks for the response.
As far as the software goes, I'm definitely interested
if there's a way to copy the diskettes. I'm assuming
you don't want to part with the originals. I'll scout
round for a utility of some sort.
Regards,
Dave
