I must have been completely out to lunch when I wrote those numbers
down. Actually, it was accidental, I took this down from a mod faq
where the author himself had confused both parts in the discussion and
I wrote down the numbers he had in that context. Man, I should have
double checked this stuff!

Indeed the original IBM part was a 174 hex latch, the 244 is indeed
the octal driver/receiver and the 373 the latch. WOW! I've never been
this WRONG in a million years! Thanks for reading the reply, Roy!!!
And here I was thinking nobody read this stuff...
My sincerest appologies to all concerned!

 M*i*k*e
