fine in this design, of course, but the whole point was to be historically
accurate, and the article to add a 1861 _does_ list a 74L00.
The actual machine in question is not a classic, but the design certainly is.
By "Popular Electronics Elf", I assume you mean the COSMAC Elf? 256 bytes of
RAM, two HP hexadecimal LED displays (I used TIL311s instead), toggle-switch
data input and a CDP1802 CPU :)
I built one - nice little machine. Never really used it though.
Later.
