PIC Programmer for PIC16C84 etc.

This Programmer is powered by the RS-232 and it works with RS-232 levels at only < ±7.9V.

The Programmer works for programming 24Cxx and PIC16C8x only. It is improved by removing the 100nF capacitor, C2. The capacitor slows down risetime and may cause a problem with In Circuit Programming. Use Programmer 2 to program 12C508. The programmer may do, but Programmer 2 is better, and there is no spikes on Vpp.

The high Vpp is obtained by using the negative voltage to drive the chip. The voltage is stabilized with zener diodes. This makes it possible to use extra low input voltage.
Transistor driver guarantee output level > ±3V.

The Programmer programs both PIC-12C50x, PIC-16C84 and 24C16 EEPROM's etc.

EEPROM adapter for this programmer. (Supports Automatic Switch Function and LC types.)

Download utilities, PGM84V28.ZIP (25K).
Download PIP-02 driver, JDM84V23.ZIP (10K).
Works with old PIP02, DOS only (Not Windows dos prompt).


Use PIC Programmer 2 Instead.

Z80 trick: Use RESET, NMI and CLOCK to bootload a romless system (RAM only).
