* LAP6 format tapes
* LINCtapes from <a href="https://museum.syssrc.com/">The Computer Museum @ System Source</a>.
* These are tapes for the original LINC computer.
*
*AJH-tape-1 and AJH-tape-2 only have one check word instead of the normal 3
*checkwords the other LINC tapes have. The documentation says the 3 check
* words were to ensure the reverse block mark wouldn't be overwritten.  These
* tapes don't have LAP6 index. They do have some text source code.
* In the text I saw dates from 1963 to Janunary 1965.
* Tape 2 block 70 has read error. The forward block number is wrong and
* checksum doesn't match. Looking at analog waveform it doesn't look like read 
* error.
