* 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 
<a href=splice1.jpg>was spliced</a> on the
* end to give enough blocks. <a href="splice2.jpg">Other side</a>. Most of them had leader between the two sections
* and <a href="danreel.jpg">a mark on the reel</a> 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.

*
* Dan4b block 467 is bad which corrupts danmark manuscript.

*
* 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.
