Cyrix MII 300GP/66x3.5

A lot of CPU's in my collection look almost identical from a distance. It's hard to tell a Pentium 100, 120, 133 or 150 apart if you aren't close enough to read the sSpec information on the chip. The logo's and detailing on CPU's often stay identical in its course of production.

There are exceptions however and Cyrix really wanted to shine as the odd one out!

1 (this CPU). Cyrix MII 300GP/66 with big MII logo
2. Cyrix MII 300GP/75 with big MII small v logo
3. Cyrix MII 300GP/66 with buig MII 'dithered' logo
4. Cyrix MII 333GP in black
5. Cyrix MII 333GP in grey
6. IBM 6x86MX PR300 in black

The latter is based on the Cyrix MII but sold as IBM product.
