There is SSI and there is MSI
In the latter days of MSI it got a bit
LSI-ish
TRUE-LSI was reserved for P-Mos N-Mos and upward.......

Am I the only one who finds it a bit perverse that there are 74xxx standard
TTL circuits for such complex functions as ALUs? I thought that the way to go
would be to construct it out of simpler TTL circuits, such as all the 740x
gates, not buying it as a package. I suppose I'm not used to the concept of
single 74xxx circuits carrying out such complex tasks.

Iggy tipsar: Koppla aldrig en C128-transformator till en A500. ?ven om
kontakterna ser likadana ut, ligger sp?nningarna fel.
