It is with great disappointment that I must announce that VCF 5.0 has
been tentatively cancelled due to a lack of interest from participants.
Exhibitor and vendor sign-ups have been extremely low, and the
impression I get is that interest has waned this year.
I made one last push this week to encourage exhibitor and vendor sign-ons
to no avail. Granted, the planning for VCF 5.0 was much shorter due to
VCF East, but I thought that as soon as I sent out announcements (on
July 31st) that there would have been a flood of sign-ups. That didn't
happen, leading me to believe that perhaps exhibitors and vendors from
past years are too busy this year with the economy being the way it is to
consider participating.
There are numerous advantages to holding the event on the planned dates,
but without any exhibitors or vendors, there wouldn't be much of an
event to present. The admission price would have to drop to a level
that would not justify the cost of holding the event.
However, if the interest is there, but has just not been expressed
properly, then I would very much like to find out. If you did plan on
attending the VCF this year, either has an exhibitor, a vendor, or just
an attendee, please let me know about it. Below are three links to
visit to either signup as an exhibitor, a vendor, or to indicate that you
will be attending. If the response to this is positive, VCF 5.0 will
go on. If not, VCF 5.0 will be cancelled.

For general comments or feedback, please feel free to e-mail me
directly at <sellam(a)vintage.org>.
I do hope that there is an overwhelming response to this announcement
and that the VCF will go on as planned. However, it's up to you to do
your part and let me know.

My Apple II+ Keyboard Encoder card is faulty and I would like to know if
it's fixable. I've tried several different keyboards and 2 motherboards so
I'm certain it's the encoder. I've ran a keyboard diagnostic and it is
acting as if the control key is always pushed but it is not. It does it
with 3 different keyboards so it's not a "stuck key" problem. Any ideas or
help much appreciated. Thank you.

They're all over teh place here as well. They won't be going away
anytime soon; they're very popular in the embedded systems market.

My guess:
Raw integer performance: 500+
Reliability: 0.5
Elegance of Quality of design: 0.1
Programming enjoyability: 0.5
Innovativeness: 0.5

it's a nice skill to have in *addition* to knowing how to
use the assembler, construct an application, etc. for the
system in question, we used SoftIce as the debugger. I'd
set up bounds-checking breakpoints to catch the errors
of programmer #2 (best friend of #1, the physics major),
who simply *refused* to range-check any values...

I have a bunch of 17" and 21" NeXT color monitors here in the DC
area as well, cheap, if anyone is interested. No, I won't ship them.

In the early 80s I worked at Sight and Sound Music Software,
which had titles for the C-64 like Kawasaki Music Synthesizer
and Kawasaki Rhythm Rocker.
Ryo was already an established musician, and still is. See
http://www.google.com/search?q=ryo+kawasaki . However, he
also coded for the C-64 without an assembler. He just used
the debugger. There was no source code. We first figured
this out when we asked him how he did a certain effect,
and he started reciting the hex opcodes. He didn't really
know the mnemonics, he just memorized how to create the
hex to match the opcodes he wanted.

Subject: Amiga 500 and stuff
Hi,
I have an Amiga 500 with monitor, extra floppy drive, 500K memory card
and 4 boxes of software. Also have a Panasonic dot matrix printer - all
vintage 1985 - and all works. I have several of the kernel manuals too.
See the attached photos. Note the original boxes.
I'm about to toss everything into the trash unless there is someone
interested in collecting it, or even using for spare parts. I'll pack
up and split the shipping cost (from Fairfax, VA) with anyone in the US
who wants it.
Please let me know if anyone's interested by September 8th.
Best regards,
Jim Fraser

I worked for a while with a Physics major who'd learned machine-language
programming for the IBM PC using DEBUG.COM. He also had no conception of
source file structure.
After we hired him, he was assigned some programming tasks, and sent off
to do his thing. A few days later, he asked me how to include his code
into the system. I asked him for the file name, and just included his
module in our batch files that did the system build.
Kept getting errors on his module, so I asked him to assemble it and
go through the listing and correct his errors (I hadn't even looked
at it).
"What's an assembler?"
He was keeping multiple, un-related subprograms in a single monolithic
source file, with none of the assembler directives that were needed to
define the program's memory model and segment use. Also, no TITLE, etc
stuff to make it pretty. I took the one subprogram whoes operation I
could fathom, rewrote it to comply with the memory model, added some
other directives, then shot it back to him and told him to either
make each subprogram a separate module or figure out which *should*
be together in the same module (based on data defs, etc). He wouldn't
do it, and instead kept everything together. Then, he'd go through
the extra work of extracting the subprograms, and placing them in
separate source modules... but he'd do this extraction *every* time
he made a set of changes to his huge monolithic source.
I left there in 1990; on a visit back in 1995, I found he was no
longer writing code, but was confined to performing installations.
Thank God!

I have two P/390s, one P/390E, an S/390 G1, and an old non-working ES/9000
that I want to get working soon.

What kind of stuff do you have?

The Prime 2455 is set up and occupying the largest space, but

One of the three Apollo's (the DN2500) is on the card table that

The PDP-11/23 is still in the hands of the buddy who rescued it
for me (yes, for me, he has enought of them)...
The Tandy 2000 is in storage... the Mac IIci is set up and running.
The SOL needs dusting and prayers for the tantalum caps...
The Objective Design S-100 frame which sat on the SOL in a previous
incarnation needs the big electrolytics reconditioned...
The Zenith Z-150/151 (I added a newer CPU card) was operational until
1995, and I haven't turned it on since. I moved it from on top of the
clothes dryer to a spot next to it. The monitor is still on top of the
dryer, tho...
However, no SWMBO to provide advise, consent, or alternatives... ;-)
