PICextern 4X

ITāS A LITTLE BOARD WITH 2  2764, 2 6264, 1 74138, 2 74373 and 1 MAX232.
IT RUNS AT 10MHZ, AND CAN RUN THE PIC17C42/43/44 MICROCONTROLLER 
PROGRAMS.
IT WAS CONFIGURED FOR MICROPROCESSOR MODE.
I DID FOR THE BOARD, A SIMPLE PROGRAM THAT LOADS A .BIN FILE INTO TWO 
EXTERNAL RAM AND EXECUTE IT, USING THE SERIAL AT 19200BPS.
THERE IS A D.O.S PROGRAM THAT DOES COMMUNICATION WITH THIS BOARD TO 
TRANSFER THE PROGRAM.
I HAVE REVECTORED THE INTERRUPTS FOR THE EXTERNAL RAM.
OTHER ADDON FOR THE BOARD, IS THE POSSIBILITY TO SAVE YOUR PROGRAM 
(THATāS WAS RUNNING ON RAM) INTO 2 EEPROM THAT YOU CAN PUT ON THE PLACE 
OF THE ORIGINAL 2 RAM! :). WHEN YOU FINISH TO SAVE, YOU PUT THIS 2 EEPROM 
ON THE PLACE OF ORIGINAL 2764 AND READY! YOU HAVE YOUR NEW SOFTWARE. WHEN 
YOU WANT TO BEGIN A NEW PROJECT, PUT AGAIN THE 2 2764 ON THE PLACE! YES, 
ITāS A ĪEEPROMā PROGRAM TOO! (FOR THE PIC PROGRAMS, OF COURSE!)

HOW MUCH? NOT EXPENSIVE FOR MY COUNTRY!

R$179,00 OR U$160,00+SHIPMENT
IS IT A GOOD PRICE?
