I think much older than that. Being an old git my mind is unclear but I am sure I remember using a Z80 to talk to them possible as early as 1980.
You could be right. I just figured that if I got one surplus in 2004, they were likely out at least 5 years prior to that. Digging into my displays box, I now see one of them that I bought at the same time in 2004 has what is likely a date code of 1991 on it.
