I a building a copy of the Altair 8800.

The 74367 has been used as a substitute for 8T97 on peripheral cards.

The 8080 CPU card uses 9 8T97 chips. Since the 8080 CPU can't drive a standard TTL, should I use a 74L367 on the CPU card?

Also, what are your favorite places to get L series logic chips?

Thanks, Grant

I think the 74L family is obsolete - and so are most parts in the plain 74xx family. You will probably have to use 74LS or 74ALS now.

I have several used N8T97 chips which you can have for the cost of postage from Australia. All are socket pulls out of a minicomputer system from the early 80's.
