I like to use the JANET tester but that might only work for JANET sites.
The other one I often use is the one at http://www.abuse.net/relay.html
which seems to work well (and won't end up blocking your domain if the test
fails).

Hey, Cosmac people -- I'm working on a Chip-8 emulator for, natch, the
Commodore 64.
There is a nice instruction set listing at
http://users.aol.com/autismuk/chip8/chip8def.htm
but it doesn't well document how the carry in register vf is used. For example,
does 7rxx use the carry even though it doesn't set it? What about 8ry4 or 8ry5?
These set it for borrows/carries but do they use them in the addition or
subtraction, like the 6502 ADC/SBC?
Also, what does 'skip' mean? Skip the next instruction?
Thanks!

Anyone have any favorite sites or tools to test an SMTP server for open
relays? I finally got around to updating the SMTP configuration on my VMS
server to reflect the upgrade from TCPIP 5.0 to 5.1 and would like to test
it.

Hi,
Well, a diskette jammed in the PB 5300ce's drive last week,
and in addition to a spring or something broken or missing
on the eject mechanism, I seem to have knocked the upper
head out of alignment, so it's kaput (and the topic is
admittedly off-topic as the 5300 is a 1996 product).
Assuming no one has one, I'd really appreciate it if those
of you who come by such things on a fairly regular basis
would keep an eye out for one. They may be unique to the
5300, or may be used in one of the contemporaneous models.
I'm sure Shreve Systems likely has them, but their prices
vary widely, perhaps based on supply/demand, perhaps not.

I just got one of these. It powers up, the lights on the back flicker
nicely, and it appears to be outputting crap to the MMJ serial port
labeled '3', but for the life of me I can't figure out what speed it's at.
I've tried minicom at 300,1200,2400,4800.9600.19200,38400, and 57600 with
no success. I've even tried 7-N-1 and 7-E-1 (7bits no/even parity and 1
stopbit) along with 8-n-1, no luck.
Anyone have more of a clue than I do?

There should be a little slide switch at the back. When it is
up it will use that port (3 - with the printer icon) at
whatever speed: usually 9600 8-N.
I've never tried via a minicom - do you have a
dumb terminal, preferably a VT200/300/400
and a known good set of connectors and cables?

I'm trying to get one, and wondering what success people have had with
connecting them to a PC using "X-Cables" and "Star commander" to transfer
data ( http://sta.c64.org/sc.html ). Also, is there any chance of making
a 1541 read an Apple ][ disk? I know they both use GCR encodings for
their disks, and it'd be really useful if I could read disks on my PC.
Also, does anyone know anywhere I could get a Compaticard (and any
necessary drivers to make it useful)? I've looked on ebay a few times now
and still haven't seen one...

One of the 4's was for the bus size. It was a multiplexed
synchronous bus. It had 8 phases. 3 were for address and
one was for the rom. One or two were alu and I don't recall
what the other was for but I think it was bank selects.
Each device would watch the instruction and would do the
right thing ( I/O or RAM ) when it's time came around.
One might call it smart I/O. This way, the processor didn't
have to have the additional pins to select the function
for the bus.
