Thought I would post this here in case it reaches eyes my forum posts don't. ?So I
finally got my hands on a SWTPC 6800! ?
This machine is chock full of boards.. 4 ram boards, the cpu card (with SWTBUG ROM), MP-S,
MP-C serial cards, a floppy controller, some little custom board, a sound card.. etc.
This presents some challenges obviously, since the machine has been altered from stock it
could be tricky getting it running.
Before I had it stripped down, I tried powering up as is (i pulled the older MP-C card and
put MP-S in slot 1). ?This produced little except for a string of random characters that
would repeat every time I hit reset, exactly the same number.
I tried stripping it down to CPU card, MP-S, and the RAM board designated as '0'..
but all I get at the terminal end is a single random character on power up. ?
I then thought I'd try my luck putting the CPU card in my working MSI system (taking
out its card). ?Nope. ?
Now, because my CPU card has been modified to accomodate SWTBUG and possibly something
else, I'm not sure if it'll even work in a stripped down config. ?Not sure about
the interplay between boards.
Anyway.. if anyone has any thoughts to point me in the right direction I'd be most
appreciative. ?Ultimately I'd like to get this beast working with my CT1024
terminals.

I saw an SWTPC booth registered at VCF West, maybe you should drop by.
I'll look in and see what they have and maybe they can help too.
Only SWTPC gizmo I have is one of their audio amplifiers somewhere in
the pile. Picked up at TRW Swap Meet.
Thanks

You need to start with the power supply. Verify it's ok. Then work
through each card's jumpers to see how they are set. For example the MP-S
has baud rate setting options, and the card can be used with a Teletype or
RS232 terminal. 1200 is max baud.
If you're getting a consistent but garbled output to the screen did you
confirm the baud rate you're using matches the MP-S jumpers?
All of this is well documented online, Mike Holley has a step by step set
up on his site. A few years ago I retyped the entire code listing of TSC
BASIC which can be downloaded into bare bones SWTPC 6800

There was someone with a table at VCF-East for the past two years who had
new SWTPC replica and enhanced interface boards. He also had interesting
kim-1 peripheral boards, with things such as booting from SD-card support.
I cannot remember his name right now, but I have one of his coffee mugs
somewhere, so can find it out and follow up, if no one else beats me to it.

I think this 6800 is live but I am being dogged by my inabilities when it
comes to cabling. I'm going to purchase a 'proper' db25 female connector
and the molex pins for the MP-S connector and solder it up. I tried sort of
using jumper wires to make it go. When I turn the 6800 on, the PC terminal
I'm using reacts by producing single or strings of random characters.
According to the SWTPC 'system checkout' stuff, if I get anything at all
showing up on the terminal it usually means the 6800 is alive. Based on the
notes written on the MP-S, I'm confident I have the correct baud rate and
bit (8) and parity (1) settings, but alas, doesn't seem to work. When I ran
into this sort of thing with MSI 6800 it turned out the baud rate switch on
the serial card wasn't correct, despite factory labelling. That might be
the case here but not really sure how to sort it.

"Random Stuff" on serial ports can be a speed, data-bits, or even parity
mis-match.
I assume you have tried tweaking these?

Sounds like you have the proper connections...

Try different speeds in your terminal emaulation program?
