# SOL keyboard
|
|
|
|
This keyboard replicates the keyboard on the SOL-20.
|
|
|
|
The keyboard is designed using KiCad in order to be the most useful for anybody
|
|
wishing to modify the keyboard for more specific uses, or to add to the project.
|
|
|
|
The keyset for the SOL-20 keyboard consists of the Unified Keyboard Project
|
|
classic ASCII keyset, with a special SOL-20 add-on keyset.
|
|
|
|
## Differences from the original include:
|
|
|
|
1. The original keyboard is a capacitive keyboard. This keyboard uses standard
|
|
switches (either Cherry or Futaba).
|
|
|
|
1. The original keycaps have an 11 degree angled stem. It may be possible to
|
|
find such keycaps, but I was unable to find any. It also may be possible to
|
|
create 11 degree adapters. But this keyboard uses straight keycaps. I have
|
|
tried both styles, and do not find a difference in typing comfort or speed,
|
|
althought there is an aesthetic difference. There is s tiny bit of space
|
|
between keys using straight keycaps, so an 11 degree adapter may not require
|
|
any change to the layout.
|
|
|
|
1. The original uses UPPERCASE+REPEAT to reset the system. For technical
|
|
reasons, this version uses CTRL+MODE_SELECT to RESET the system.
