Subject: Issue 1 versus issue 2 of Master 128?

Mike,

Indeed, you are not imagining things, at least not this time. From the Aug
89, Acorn User note published by Acorn.

----cut----

On Master 128 issue 1 boards a 470 PicoFarad capacitor should be connector
between the East Leg of R137 and the east leg of R153 which are located
directly to the east of the modulator. Connections should be made on the
component side of the PCB with the leads of the 470 PicoFarad capacitor
being soldered directly to the leads of the two resistors.

On Master 128 issue 2 boards link LK11 should be made.

----end of cut----
