Analog-to-Digital Sampling Routine for the TS1000

An 8-byte Z80 machine code routine stored in a REM line for use with the ZEBRA Analog-to-Digital converter, suitable for low-speed sampling (once every several seconds). The disassembled code reads a specified port, delays for A-to-D conversion, and returns the result in the accumulator. A sample 10-reading BASIC wrapper is included.
