ZX Spectrum keyboard tester



Keyboard tester program for ZX Spectrum computers. It builds into both a ROM image that can be burned onto an EEPROM to replace the spectrum ROM (very convenient on the Pentagon128k with its jumper-selectable second ROM), and as a tape (.TAP file) for loading regularly.

You may also get the latest source code from my git repository:

git clone http://nuclear.mutantstargoat.com/git/zxkeybtest


To build zxkeybtest you will need the vasm Z80 assembler (old style syntax version), the vlink linker, and the utility appmake from the z88dk project (only if you intend to generate the tape file).

Once you have installed all the build tools, simply type make to build both zxkeybtest.rom and zxkeybtest.tap. Alternatively use make rom, or make tap, to build just one or the other.
