- Six FX Circuits, February 1985

The missing pin numbers on IC5 of Figure 6 (Chorus Unit) are pin 6 and pin 7. C16 is connected across them. The component numbers missing from the sequence do not represent missing components, but simply resulted from the author's worthy efforts to reduce the number of components in the design.

-Speak Board, January 1985

People building the Speak Board for the ZX Spectrum and ZX81 have experienced some problems. These are in both the software and the hardware.

They are not extensive and we are well on the way to sorting them out.

Corrections will be published in the May edition, or write to the Editor requesting a correction card.

We apologize for any problems or inconvenience resulting from misprints. Updates appear in Stop Press as soon as they are available, or write to the Editor.
