This page contains information and notes related to a collection at Makerspace Nanaimo of data cassette tapes for late-1970's KIM-1 microcomputers.

There is a collection of links to websites, documents, and files for KIM-1. Also, information about the cassette tape collection at Makerspace Nanaimo, including .wav file recordings and the program data read from the tapes will be posted here.

KIM-1

The KIM-1 microcomputer was designed by MOS for their 6502 CPU, it cost $245 when released in 1976.

Micro-KIM

Micro-KIM is a nearly-100%-compatible KIM-1 clone, made in 2007. (no longer sold)

Corsham KIM Clone

Corsham KIM Clone is designed and built by Bob Applegate, revision 4 of the board released Feb 2019.

Cassette Data Storage

KIM1-CassettePulseTrain.png

Data is stored as a series of 2415 and 3623 Hz tones. The duration of one bit takes 7.452 milliseconds.

From Wikipedia:

Each bit is represented by three 2.484 ms long tones. The first is always 3700 Hz, the middle is 3700 Hz for "0" or 2400 Hz for "1", and the last one is always 2400 Hz. This gives an effective bit rate of 134.2 bit/s. Detection is done through a PLL using LM565.

The format of data on the tape is: 100 bytes with the value 0x16 (SYN, Synchronous Idle), one byte with the value 0x2A (*), the record identification number, the start address (two characters for the low byte of address, two characters for the high byte), the end address (in the same format), the actual data, one byte with the value 0x2F ("/" character ), a two-byte checksum, and two bytes with the value 0x04 (EOT, End Of Transmission).

Each byte of memory is stored as two sequential ASCII characters on tape, for example, hexadecimal B5 in memory (181 decimal) would be stored as two sequential ASCII characters "B" and "5" (42 and 35 hexadecimal).

Program: TONES A0 - Sound effect

This program starts around 1:36 into cassette tape - it's the first program stored on the tape.

Audio on the tape preceeding this program:

This is a sound effect subroutine at address 0200 to address 022C.
It can be varied to go up or down in frequency in any number of repeats.
Start with a jump to subroutine at address 0200.
ID is A0.
