ELECTRONICS AND MATHEMATICS

FEBRUARY 2009 - I am back in electronics.

Here some pictures of the early MEMTECH 8080 sytem :

   

THE CPU BOARD                                                                THE RS232 BOARD

    

THE TAPE I/O BOARD                                                        AND THE SWITCH I/O BOARD

Here my first attempt to make a schematic of the CPU BOARD :

- I liked the memory organisation of the board but I was disappointed of those small memory spaces.

 

I would be very happy if somebody could find a mistake here or if somebody could leave me a constructive comment on about how to use the CPU board.

Further I have been browsing in the net to find a suitable assembler for the 8080 and I found a free assembler as well as a disassembler for windows and if you are interested so contact me at my e-mail adress : dukapaja@yahoo.com

 

 

 

 

 

HERE A SIMPLE DATA RECORDING PROJECT :

  

With the TLC548 you can make a cool data recorder on the RS232 port of your PC. Here I implemented three frequency counters from 0..5kHz and one AD converter in the small module.
