I have a chip here, an 1101 marked "sample" with a datecode of 7103. Very likely it is a second sourced Intel 1101. The logo is a new one on me, and I think it may be a mutant AMI, but from my resources, I am just guessing. I dug up a 1970 AMI databook, and the logo does not match. The one on the book is the A over M next to I version, and the thing on the chip looks like five lines next to each other, with the first line being somewhat curved (sort of like a half-circle) and the last being a tad shorter with a dot over it. The standard mid 1970s AMI logo is simply A next to M next to I. Does anyone know if AMI tried a strange logo between the two known ones - perhaps one that matches my chip? Could this logo not be AMI? William Donzelli aw288(a)osfn.org
