    Programming other cards (I have not tested)

    Set switch 1 in position A
    Use switch 2 to switch between master/slave chip (RB6 CARDS)
    Use switch 3 to switch between RB7/RB6 cards (RB7 in position A)

    If you program wafer card (or PIC and EEPROM in a socket) only, you can use shorts insted switches:

Stupidpipo - origin designed by Gotcha67

stupidpipo.bmp - PCB of serial programmer Stupidpipo
stupidpipo_o.bmp -  layout of components

It is the simplest version of the Ludipipo serial PIC programmer. It don't require a separate power supply, but takes the power from the serial port of a PC. Connection with the PC is made by a cable 1-1, 9pin connectors, male-female.

Stupidpipo

List of components:
-------------------
1 x slot for ISO card
1 x female 9pin connector RS232
1 x resistor 1K0
2 x resistor 2K2
1 x resistor 10K
1 x resistor 22K
1 x capacitor 10-100uF/10-16V
1 x 1N4148
1 x Zener diode 5.6V
1 x LED green

Programming piccards with PIC16F84A

The simplest way, how to modify Ludipipo for programming PIC16F84A, is a parallel resistor about 8K2, which is connected to resistor 10K. The value of  parallel resistor can be reduced to 4K7, but the serial port can be demaged.

Better modification is to use an external power supply. A circuit, which is used insted of the resistor 10K, is described in the next picture:

te_20_sex_o.bmp -  layout of components

    Programmer TE-20 SEX is based on the JDM2. (Origin schematic diagram is in jdm2.bmp.) The programmer is suitable for programing PIC16F84, PIC16F84A a PIC16F876 (wafer cards and piccard2) in socket as well as on the board. EEPROM 24Cxx and processor 12C50x can be programmed in a socket only. (To program EEPROM on the board  Phoenix or Smartmouse must be used.)

    It don't require a separate power supply, but takes the power from the serial port of a PC. Connection with the PC is made by a cable 1-1, 9pin connectors, male-female. Some pins of sockets must be cut before mounting.
