LCD display for System80B
I made this in 2016 for my testbench ( project name 'GODI80B') and though it might be usefull for People who want to build their own testbench. It only need a few components and is driven with 5 Volt only
Sometimes the output is a Little bit 'flaky', but fo a testbench I think it is OK.
In theory, with a bigger LCD display, this can also be used within a pinball. If you want to use it and need a better output let me know, and I will try to understand what I coded 4 yers ago ;-)
- - a HD44780 compatible Display 2 rows, 24 Digits
- - PIC 16F726 (plus my Software, see below)
- - a 5K Potentiometer
- - 2 LEDs
- - 2 resistors
- - Edge connector for 'J2'
All 'HD44780' compatible displays should work, you can even use a 4x20 Display.
In case you are not able to program the PIC yourself just contact me, I can send you a programmed PIC at my cost price plus shipping.
