* SWTPC 8K BASIC VER. 2.3 * BY ROBERT UITERWYK * COPYRIGHT 1978 * SOUTHWEST TECHNICAL PROD. CORP. * 6/16/78 For the SWTPC 6800 computer; archived from original cassette tape. This tape's data is encoded in the original 300bps "Kansas City" format (a.k.a. Byte format), designed to be read via SWTPC's AC-30 cassette interface or similar. The cassette contains two sides, a "Binary" and "ASCII" side: - The ASCII side contains the program as one long file in Motorola S-record format (the native format of the MIKBUG and SWTBUG cassette loader) - The Binary side contains a small loader stub in S-record format, which in turn is able to load and verify a binary version of the program which follows it on the tape. This was a much faster way of loading than relying on the full native ASCII coming off tape. (The Binary side also contains a small third text file, containing the copyright banner reproduced above.) N.B. the "Binary" version (file 2 of side 2) is not itself an exact image of what ends up in RAM; it contains "chunk markers" interspersed within the data stream. So if you're mainly looking for the program code for use in emulation or piping in via terminal transfer, the "ASCII" version will likely be the simplest startng point. The program ultimately loads at address 0x0100 via either mechanism. Happy computing! -- Ben Zotto, April 2022. -------- Included in this archive: - Side 1 (Binary): tape audio in WAV form, three data files decoded from the audio. - Side 2 (ASCII): tape audio in WAV form, one data file decoded from the audio. - Photo of the original cassette - This README file.
