DEC-12-OSYSB-A-AC1-b.linc	OS/8 VIII System LINCtape #1 1/18/74. Block 76 bad. It appears the writing of block 75 continued over reverse block number and forward block number of block 76 and likely the rest of works in block 76. Block 76 is in OS/8 scratch blocks. The OS/8 system head, CCL.SV, and LIB8.RL are different than tape above with same name. Tape above has additional files disk.sy, linc.sy, and lnkfmt.sv.  Captue shows the beginning of block 76 on top and same block from another tape on bottom which shows the normal waveforms for the D0-D2 tracks. The waveforms are good level just wrong. <a href="DEC-12-OSYSB-A-AC1-b.png">Bad block number (aD0-aD2)</a> <a href="DEC-12-OSYSB-A-AC1-t1.jpg">picture 1</a> <a href="DEC-12-OSYSB-A-AC1-b-t1.jpg">picture 1</a>
