pdp8-tape2bin's Introduction

pdp8-tape2bin

Converts a PDP8 bin/rim tape-file into a plain binary file that is suitable to be loaded into the ram/rom/eeprom of a hardware emulator like Logisim or Digital.

./tape2bin.sh <test.bin >test.eep

This is what a hexdump test.eep looks like:

Octal dump

This repo also contains a small utility to dump a bin/rim tape file into an octal hexdump-like format that is targeted for PDP-8's.
