PDP-8 File list for dial/Dan

These are a collection of media images in DIAL format
Images of DIAL LINCtapes used on a PDP-12 by Daniel Gray
They are unusual since they have two 512 block DIAL systems on most of
the tapes. Since the tape isn't long enough extra tape
href=splice1.jpg>was spliced on the
end to give enough blocks. Other side. Most of them had leader between the two sections
and a mark on the reel showing where the second section starts. dan5 doesn't.
Class-assignemnts only had one section.

I had problems reading these tapes. These errors exist but are outside the
blocks used for data so no files are bad.
Dan0b trailing blocks 513 and 514 are bad.
Dan2 trailing block 520 is bad and is the last block.
Dan4 block 517 is bad and is the last block.

Dan1b block 469 is bad which corrupts mildred manuscript.
Good copy

Dan4b block 467 is bad which corrupts danmark manuscript.
Good copy

I'm not sure what is going on with safety tape. It looks like some files are
corrupted but multiple read give same results with no checksum errors.

 Image Name  Description 
 dan0.linc Various programs picture 1 picture 2  
dan0b.linc Mostly sources, some are for binaries on first section of tape. picture 1
dan1.linc DIAL sources and other programs. picture 1 picture 2
dan1b.linc PIP, Index utility, spectrum acquisition source. Block 469 bad.
dan2.linc Data acuisition and processing source. picture 1
dan2b.linc Tape is copy of DEC-12-SE2E-UO but since only 512 block all files past that are not accessible. Had TC12-F and THREEDE not on other tape.
dan3.linc Various programs source and binary. picture 1 picture 2
dan3b.linc PDP-12A UTILITY AND DATA REDUCTION. Fast Fourier. Some LINC-8 source.
dan4.linc Various programs and source. picture 1 picture 2 picture 3
dan4b.linc Various demo program instructions and demo monitor source. Irvine demo. Block 467 bad.
dan5.linc Various sources. picture 1 picture 2
