So, I just picked up an MISE from Bartlett Labs (cause I really liked the M3SE I had) and decided to revive one of my TRS-80 MOdel I's. In my box of "stuff" I found an interesting ribbon cable the function of which I don't know. It is a 40 pin to 50 pin ribbon cable with a black box connecting them that is labeled TANDY. I know of nothing the Tandy made that used a 50 pin connector other than a hard disk. Could that be what this is for? Anybody ever seen one? I no longer have any Tandy External HD's but then, with things like MISE and FreHD why would one still want one other than for nostalgia.
