Used to be, you could go to Radio Shock and purchase one of those
solder-yourself 44-pin edgecards that mate with the KIM-4 expansion
board. I'm thinking one way around my dead keyboard issue which
also solves my desire for expansion would be to add a CPLD
decoder, 32K SRAM, 32K ROM (with holes around the 6530s
and remapping new patched monitor into $1800-$1FFF), and 6551
UART/MAX232 combo to input code and d/l intel hex. (The cassette
interface on poor KIM is dead, too.)
By the way, if anyone's interested, I have a generic 6502 Intel Hex
program downloader program that allows you to assemble and directly
download programs from the development PC into your SBC.
It's freeware so have at it if anyone finds it useful.
It's at:

I've gotten some griping about my selection for the location of the first
VCF East.
No doubt, a good majority of folks will be quite happy with the selection.
This is no accident. The site was chosen based on the demographics I
collected. Most of the attendees will be coming from Massachusetts and
surrounding areas.
As with any sensible business decision, it was based on what will
hopefully bring as many attendees to the event, which in turn means I will
be able to recoup expenses and will therefore want to continue to do
Festivals on the east coast.
I received over 150 responses to the VCF East survey. Here is a summary
of the results:
This chart shows the number of responses received from each state, sorted
by number of attendees in descending order.

- Nearly 25% of potential attendees will be coming from MA alone
- 40% of potential attendees will be coming from the New England area
- If you include NY, PA and NJ with New England, nearly 70% will be coming
from this combined northeast region
There was also a strong desire to keep the event close to the Rhodes
Island Computer Museum and the Retro-Computing Society of Rhodes Island so
that tours to those facilities could be organized. Providence is only
about 45 minutes from Worcester. There are also several other museums
that I hope to get involved with the event, including the MIT and
Harvard museums and the Computer Museum in Boston.
Worcester is still within only a few hours of where most of the potential
attendees will be coming from. I don't know how you east coast folks
perceive distance, but I've lived in California all my life and a 6-hour
drive from the San Francisco bay area to the Los Angeles area is no big
deal to me. I made the round-trip in one day a couple weekends ago to
pick up an old computer. Driving a couple to three hundred miles should
not be a major ordeal for most folks.
So there you have it, the reasoning behind the selection of the location
for VCF East 1.0. I know it won't please everyone, but the unhappy folks
need to realize it has to be held where it makes the most sense.
I really look forward to VCF East, and I hope you easterly folks do too :)

I have a Macintosh IIfx and a Macintosh Powerbook 100
that I'm removing from my collection (I'm trying to
be a little more focused). Does anyone have any
DEC items for trade? My biggest need is a replacement
Pro380 mainboard. I have the external floppy for the
PB100, but the battery is dead.

Speaking as a USian anarchist, I can say with a high level of confidence
that the United States sucks the most. Bar none. The US is by far the most
powerful corporate imperial force on the planet today, and as folks way
back in this dead horse of a thread were saying, our government is very
much beholden to various corporate interests. The last few months of the
Bush II administration (i.e., repealing clean air regs, 86-ing workplace
safety laws, etc.) must be a very explicit illustration to the rest of the
world just how much corporations (and to a lesser extent the Religious
Right) run the show .

It is a product put out by DATA-20, an outfit that used to be
in the L.A. area. It does three things: Firstly, it adds 64 k
of *paged* ram to the VIC! It gives the VIC a 40 or 80-column
mono display, and the VideoPAK also has firmware that will
turn the VIC into a data terminal.
It's a cool item, alas, it no longer works (only works in 40
column mode now). It cost big bucks in 1982 when I bought
it (something like $300). It came with a word processing
program, and a spreadsheet. My then-future wife used it in
the lab were I worked for billing, letters, etc.
It's the only one like it I've ever seen. The other ones
I've seen were the 32k model.
These guys also made an 80-column cart for the c-64 (along with
a CP/M cart).

I think that's it ... I'm moving at the end of May, so some of this may come

LOL. Nice work, Jim! Y'all can laugh at my collection, too, for different
reasons:
- Mac Plus (MacOS 6.0.8, 7.0, 7.0.1, ElfArmor, 16MHz upgrade sometimes works)
- Mac SE30 (working, details hazy)
- DEC Rainbow PC100A (MS-DOS 3.10b, CP/M 80-86, 8087 copro, 832k RAM)
= AT&T UnixPC (2, working, details hazy)
- NeXT 040 Cube (NS 3.3, OD, floppy, dreams of finding a Dimension in the tip)
The VAX 4000 VLC is off-topic until next year, right? A lot of its chips
say 1992... leaves 6 count 'em 6 legit entries. .... woo hoo, we're number
last!
Can I count my TI-59 if I rebuild the battery pack and clean its keyboard pads?

I actually don't have any heath/zenith stuff, I was just trying to organize
an excuse for a road trip to St. Louis. If I say I'm going after computers
the rest of the family will decide to stay home, otherwise they will all
want to come and visit/shop/eat. I'm just after computers.

Can Any one help me please? i am trying to interface a bar code reader
to PCI Bus via a 82C51 (UART), and i wrote a code to support my
hardware design but the software it seem wrong. Here is the code:
#include <conio.h>
#include <stdio.h>
#include <dos.h>

outp(CONTROL, 0x05); // UART now ready
}

} while(x == 0);
outp(TXREG, data); /* Send Data */
}
