Intel 1102 RAM

[chip68]

Has anyone here ever seen the 1102, or have one in their collection? I found yet another article that mentions this elusive beast, perhaps the rarest Intel chip there is:




I'll be putting the whole magazine up for auction shortly. It's got a nice write-up on the history of the 1101, 1102, and 1103 - including why the 1102 never took off, and an interview with its designer, William Regitz.

Why no visible markings on the ram chips? The others have, and look mostly like texas instruments chips.

They're marked, it's just barely visible in the photo. (Much easier to see looking at the article itself.) The package appears to be this variety:



Not exactly high-contrast. And you're right, the others are TI chips. Texas Instruments was the biggest supplier of TTL logic at the time.

The 1102 never actually made it to market. I think the 1103 made it obsolete. cpu zone has a reference to the 1102 here...

From 'Recollections of Early Chip Development at Intel'

"Custom products also got Intel started in the dynamic RAM business. Intel worked with Honeywell on a product called the 1102 (PMOS RAM number 2). Bill Regitz was with Honeywell at the time and was hired by Intel to work on an improved part, the 1103"...
