CP/M File Transfer Program Via The IEEE488 Bus.

By S. Wood

Below is a simple program written in BASIC-80 which, if present on two machines fitted with the EV Computing IEEE488 interface, will allow data files to be transfered between them at a reasonable rate. The speed loss is due to the amount of data conversion done in BASIC, but it is still faster than serial interface methods previously used. Shortly a machine code version with more features will be made available which will be able to transfer files very fast indeed (approaching 200 K bytes a second). The speed limitation then will be in the disk drives and not in the software or interface.
