TIMELINE MX-2424 CONTROL KEYBOARD MAT So far I have seenRubber mat switch, clean. The 2424 was quite a thing in its day as it was all digital but was made to look like it was a tape recorder so al the features seemed familiar. Its a bit too new for me but one came in as an exchange so I have listed these parts, As I understand this was a collaboration between Timeline Electronics in the USA and Teac as some boards are marked Timeline, they may well be used in other units of this time.
