I remember the 7488 was used in the bootstrap loader for the Data Generl Nova minicomputer. Likewise, I believe the 7407 is available only in conventional TTL. I missed the original posting on this topic. I assume it is a response to a request for a substitute for the 74LS88. I have used the Signetics S82S123 successfully as a replacement for the 7488. Same pin-out and bit order as I recall. -Jim -- ----------------------------------------------------------------------- J.V. Pieronek Internet: jvp@ll.mit.edu M.I.T.
