Errata

1. Snowdinger 2
   

   Mr. Wilitams of Shoeburyness, Essex found the 2 deliberate mistakes in the Snowdinger 2 circuit diagram contained in the last issue. The labelling on IC49 pins 2 and 6 somehow got reversed which means that pin 2 was really pin 6 and pin 6 was really pin 2. Also pin 1 of IC3 should have been connected to pin 6 of IC49 (2MHz and not 8MHz as shown).

   Mr. Williams also points out that to run at 4MHz a 220ohm pull-up resistor is required on pin 9 of IC1.

   Many thanks to Mr. Williams for pointing out these errors, its nice to get letters even if they only tell me that I made a botchup of the previous issue.
