Resuscitation 1 After several hours of patient operation, the died unexpectedly, with a faint odour of hot plastic. Might be something intermittent in the bus logic. The output frequency is derived from a reference frequency which can also be supplied externally. Both 4 and 2 ROM versions are out there. If you fail the first time, keep trying!
