- They were microprogrammed. That doesn't mean that there was microcode.
-
- For example, on the 360/50, the microprogram was stored in blown fuses; I think
- the 360/40 used ferrite cores--just like main memory. As I recall, only the
- 360/44 used a writable control store.
-
- (Some of this is from hazy memory--the book is in a storage locker. Shamir
- Husson was the author's name, I think. Something like that, anyway. I read it
- back when programmers *did* know about the internals of their machines...)

- Carter? *Carter*??? CARTER??????
-
- That suit was slapped on IBM in 1969, when I was in college, by the *Nixon*
- administration. IBM was a huge *Democratic Party* contributor. Read Watson's
- _Father, Son, and Company_, for starters.
-
- I'm not an IBM fan, but I *do* insist on accuracy in my folklore.
