WTB:old micro processor development boards

mc · Oct 27, 2003

Hi after older type early microprocessor development boards based on
early microprocessor chips (around late 70's early 1980's era).. e.g.
8080/85/z80,680X,sc/mp's,2650,TI9900,6502, 8086 etc.. not after full
microcomputers (e.g. commodores, etc.) but development systems that ere
basically a cpu chip+ some ram ,some sort of interface and i/o on a
board .. or similar setup

also any books/manuals to go with those micro' and interface to them..

May I ask why?

Sure ..like to restore them ... and I suppose collect them .. (many
people throw them away) ...and experiment with them ..to have another go
of understanding their architecture and what makes them tick. In those
days I was not fortunate to own many (built my own miniscamp, 256 bytes
of RAM!)..since then there has been hundreds of them including the new
microcontrollers that you see these days ..but to me they are too
complex ..some of the simplicity of the early micros is great e.g.
Motorola 6800 ..these days the architecture of some micros is so complex
(to give them features and computing power) that the software is
advanced to use them ... sure a pic chip will do what a whole D2 (6800)
kit did @ 20x the speed .. and more .. but sit down from scratch and
try to understand all that is happening (@ machine level)..between to
two systems ..i would say 6800 would be a lot easier.

I suppose it is sort of like the early cars and the modern ones .. well
I am enthusiast of the older ones .. But don't get me wrong I still
drive a modern car and .. and yes I also use pics (picaxe etc.) .. and
made some of the pics talk to the old micros .. for fun

..

Why do people climb Mt everest? go to the moon .. want to go to
mars..when you know exact answer to those .well .. you would have your
answer ..

Fair enough. Before too long I will _have_ to have a
clearout. Amongst my treasures are a wirewrapped
Hitachi 6303 card with various peripherals, a Motorola
6802 card with a bit of ROM and RAM and a couple
of PIAs/UART, a Motorola 6809 system with various
cards (floppy disk controller, I/O card, ROM/RAM card)
which can run the Flex OS. These were all designed by
me for various commercial projects some years ago
but were never sold to the general public as micro
development systems. I should still have all the circuit
diagrams, monitor programmes, assemblers etc.
Let me know if you're interested in them, free of charge
except you pay postage from Melbourne.

Seems such a shame to dump them in the tip.

Too bad, just threw out a 8085 development kit last week after

years in the rack, had CRT and floppy drive and was portable.

John Robertson · Oct 28, 2003

I think I still have my old 6809 Motorola Micbug (I think it was
called) board lying around...probably stripped of most ICs but more or
less complete otherwise.

Not the Sofia (Sophia?) ICE with the 8" floppy? Jeeze I spent some hours in

Thought of getting a fpga board and learning vhdl or verilog
and making your own versions of those processors ?
Quite a few different soft versions of those processors out there.

Can even run early aracade games on some of the boards with video out.

You evil souls! I had just about wiped the 6809 and its accompaniments
from my mind. Now I'm having all of these flashbacks.

6809 chip on a buggy breadboard, building hardware and writing
assembler to drive it. When it didn't work, no way to know if the
software was wrong, the hardware was wrong or you just had flaky kit.

I'm just going to go and bang my head on the wall for a while now.

Sort of .. I am not up to speed of VHDL ..have known and seen reports on
emulations of old CPU's .. some run @40to 50 times faster I believe
...but somehow that is not the same thing ... I will look @ some of the
staff you mentioned ... it is sort of having a framework of an old car
and putting a super modern engine in it ...

Mind you at 50mpis it might be a bit better?

Never had to use it.
Only one I'm using at the momnet is the xilinx picoblaze in a coolrunner2 cpld.
quite good.

Can't find the link for the eniac core.
Also a few cores or compatables for pdp8's
don't think you will find any pdp11's as Ti is a bit
sensitive with then due to msp430's etc

http://neil.franklin.ch/Projects/PDP-10/index.html.en pdp10

some other mc68XX cores and
68HC11
http://members.optushome.com.au/jekent/system68/
http://members.optushome.com.au/jekent/FPGA.htm
there is a version of this design on opencores

for pdp8's see
http://www.faqs.org/faqs/dec-faq/pdp8/section-8.html

8051's
http://www.cs.ucr.edu/%7Edalton/i8051/
http://www.vhdl.org/comp.lang.vhdl/

z80's

some nice video projects

lots of others out there.
