I have a couple of machines that run on paper punch tape. These are the machines that my industry uses and they were built so well, back in the '70's and '80's, that they are still running and nobody replaces them. Consequently, the input system is dated. Most everybody uses the CTES program and ISA card made by Centrum. They, however, want $650.00 for a new card (proprietart equivalent to a $30.00 scsi card). I have seen some archives mentioning plans to build a tape emulator on the 'net, but I can't seem to find anything that actually shows plans/schematics. Any help pointing me in the right direction would be much appreciated. All I need is the information and I can build it.
