Greetings to the List -
Does anyone have a copy of the text of the actual ISO 1863
standard that defines, I think, the formatting of the
ancient 1/2" magnetic tapes???
I am interested to understand better the format of the
calculated LRC at the end of tape blocks, sync signals,
record gaps and all the rest.
For 800 BPI I have most of this in my head, if you have any
specific questions. (I wrote up a mostly software
read/write interface for 800 BPI NRZi mag tape many years
ago on a CM/M system.)
800 BPI is a VERY simple format.
