[Coco] About those EPROMS...

[Stephen H. Fischer]

I said my memory could not fetch the method. 

Perhaps the ROM was enciphered or ????

It was short lived and the code to be protected was for a computer of high value at the time.

It was like the Toshiba thinking on the hard drive in my first laptop.

Take the SCSI interface, flip top and bottom and left to right.

I could not put a larger standard HDD in that laptop.
