USB Interface for Classic Computer Keyboards
Revised new edition of the popular Keyrah interface
Keyrah V2b is the revised version of the very popular
Keyrah V2b allows you to connect the keyboards of classic computer systems
like the Commodore 64 or the Amiga 1200 to modern computers (e.g. PC, Mac,
or the Raspberry Pi***)
via USB. It also supports digital joysticks of such classic systems, translating
the joystick events to key strokes. The list of the supported classic systems
has almost remained the same:
* There are no longer connectors fitted for the Commodore 128/128D, but those
can be added if necessary (soldering required). You can use the configuration
options to add a C128D connector (already soldered to the PCB).
- Commodore 64 (all models)
- Commodore VIC-20
- Commodore 128*
- Commodore 128D*
- Commodore 16
- Commodore 116**
- Commodore Plus/4**
- Amiga 1200
- Amiga 600
** There are also no connectors for the Plus/4 and C-116, those can also be
fitted (PCB modification and soldering required).
Keyrah V2 fitted inside a Commodore 64 case
Unlike the old Keyrah interface that required you to choose between the different
supported computer families, Keyrah V2 comes in a single version that works with
all systems. It also supports both German and English keyboard layouts, so this distinction
is also history. Keyrah V2 provides a jumper that lets you choose the desired
configuration, you can either set it to 8-Bit with German keymap, 8-Bit with US keymap,
Keyrah V2's new switch still allows you to switch between the standard and
the emulation keymap (just like the old Keyrah did), and it still looks like
the original power switch when built into a Commodore 64.
Now there's a third switch position that allows you to send an ACPI signal
to shut down/power up your computer. To avoid triggering the shutdown procedure
by accident, this third position is not locked, so the switch will always flip
back from it if not held in place. (The ACPI signal is only sent after remaining
one second in this position.)
***An internal USB connector is not present but can be fitted, which also
requires soldering. Please note that Keyrah is a pure USB device, it will not work
with USB-to-PS/2 adapters.
USB lead NOT included, please add one via the configuration options.
