WY-60 USB

This project is completed and will not get updated anymore.

QMK compatible drop-in replacement PCB for the Wyse ASCII WY-60 keyboard

The PCB is built entirely with THT parts to keep a somewhat "vintage" look to it and it uses the fullsize 40-pin DIP package ATmega32A. The controller is placed in the exact same location as the one on the original PCB.

Partslist

Count	Part
1	ATmega32A 40 pin DIP (32L works too)
1	40 pin DIP socket (optional but highly recommended)
1	2x3 pin header 2.54mm (for ISP flashing)
1	USB Mini port 5pin THT
1	500 mA polyfuse
2	6mm momentary push buttons
1	16 MHz quarz crystal
1	4.7 uF electrolytic capacitor
2	100 nF ceramic disk capacitor
2	22 pF ceramic disk capacitor
1	10 kΩ resistor
2	68 Ω resistor
1	1.5 kΩ resistor
2	3.6 V zener diode (DO-35 BZX55C3V6)
101	universal switching diode (DO-35 1N4148)

Some pictures of the first finished PCB

The Case requires some modification to make the new USB port fit.
Unfortunately the original cable cutout sits in a position where it was not possible to use it for the USB port.
