2640 (and maybe 2644, I can't remember) terminals have 8008s,
2641/2645/2648 terminals have 8080s (on different processor boards of
course). An 8080 would likely be in a 40-pin DIP (Dual In-line
Package, meaning two rows of pins). An 8008 would be in a smaller
DIP but I can't remember how small off the top of my head.

18xx-xxxx is an HP component part number (if you buy enough chips, you
can get the manufacturer to stamp them with your part number too), and
the 7xxx is probably a date code (two digits of year and two digits of
week-within-year).

Some boards made with HP house-marked AMD parts, some boards made with
Intel parts?
