1976- SWTPC AC-30 Cassette Interface (11/2024)Tags
SWTPcScope and Content
The SWTPC AC-30 Cassette Interface was introduced in May 1976 as a practical solution for storing and inputting program data to computers with RS-232 serial interfaces. It used the Kansas City standard for data storage, which was a protocol for recording digital data on audio cassette tapes at 300 baud. This standard was chosen for its tolerance to speed variations in recording devices, making it a reliable and economical option for hobbyists and early computer users.
The AC-30 allowed for the use of two cassette recorders simultaneously, enabling one to read while the other recorded. It was housed in an aluminum chassis and powered by a 115/230 Volt AC power supply. The interface was compatible with systems like the SWTPC 6800 and could be used to load and dump routines built into ROM software like SWTBUG.
