A hardware solution for Gayle PCMCIA reset bug.

The Gayle U5 chip in Amiga 1200 does not reset PCMCIA card during system reset event.

The PCB can be mounted on top of the Gayle chip inside the Amiga 1200 and does not interfere with the metal shield.

It does generate forced CC_RESET high pulse (pin 5) from system reset signal (pin 40).

The board requires:

• 4 wires to Gayle U5 pins 5-20-40-45 or alternative test points available in the A1200 motherboard
• 2 resistors (0805) 10K and 22K
• 1 capacitor (0805) 0.1uF MLCC
• 1 PNP transistor (SOT-23 BEC) - see the bottom silk screen layer
• PCB Thickness: 0.8 ~ 1.0 mm

Legend:

• pin 5 CC_RESET
• pin 20 VCC1 (+5V)
• pin 40 /RST
• pin 45 GND3 (ground)
