If I knew how to do it, I can probably put it together. Here are pictures of
Sundance's STM220 RS232 tram
Pick your favourite serial chip. Link it to the T2 bus, using a PAL for
address decoding and/or to fiddle the R/W .vs. Wr/ and Rd/ signals.
That's about it.
Seriously, it's easy to design with transputers. The bus is designed to
be easy to link things up to. I really think this is a morning's work at
most...
Unfortunately, I have very very little electrical background (almost nothing).
I can but circuits together, but that is just about it :-(
called STM220.
Thanks
You know, I wonder if it would be less work to take a T2 and hang some
kind of serial chip off it. Should be able to make said RS232 TRAM in 4
or 5 chips.
Incidentally, I've just looked across the room and noticed that INMOS did
make a transputer board with 2 RS232 ports on it. It's the B001 -- a T4 +
RAM + EPROMs + a couple of RS232 ports (using an SCN2681 chip). It's not a
TRAM, though, it's a 6U extended eurocard.
Hmmm, got to take a look at it. I might have some old product brochures laying
around somewhere...
I am sure I could design a RS232 TRAM, but I am not going to suggest a
circuit that I've not personally built and tested. And I don't think I'm
going to be building one soon...
Too bad, it would make a perfect GNU-style hardware project. Any takers??? BTW,
I am planning on connecting the Lego Mindstorm kit to the transputer so that i can
do some cheap robotics off the transputer farm I have. That is why I need an
RS232 tram for....
