The operational differance is which kind of program you boot from floppy. There is a 6-bit language called CORA, which is set up for human beings punching paper tape from keyboard perforators. I believe this language is invariant across the whole Linotron family of machines. There is also an 8-bit language called Binary Byte, which is more oriented toward the computer output, and which I use in my software. As an example, let's talk about skipping ("leading") 130 points of film. In CORA you would code > A 1 3 0 <, where > and < are special FORMAT control codes, and individual (decimal) digits are given for the data. In Binary Byte this would be coded as (212) (202) (001), the (212) is the leading code, the (202) is a (>128) flag and the low order 7 bits of the data, the (001) is the high order 8 bits including sign. Note that Binary Byte used 3 bytes, compared to 6 bytes for CORA. (Modulo the fact that the CORA bytes were only 6 bits). When you start talking about plug-to-plug compatability, I think you need to take this language differance into account... Ben Cranston ...{seismo!umcp-cs,ihnp4!rlgvax}!cvl!umd5!zben zben@umd2.ARPA
