A pair of 25Mhz Motorola 68NC040 processors. While the 68LC040 lacked an inbuilt FPU, and the 68EC040 lacked both FPU and MMU, the 68NC040 lacked FPU, MMU, and CPU to come in as the cheapest 25Mhz processor on the market in 1991.

A picture of two slightly purple ceramic package PGAs typical of the early '90s. Each is a rectangle with a large complete square hole right through the middle, as no silicon was required for correct operation. One is pin side down on the desk, while the other is tilted at a fun angle sitting over the other, with gold pins pointed upwards.

@NanoRaptor There's a certain longing when you're missing an FPU

#MeIRL. Also longing for an MMU, more than 4GB RAM, and... oh yeah, COLOR!

(Of course, NOW I long for the days of monochrome-capable operating systems. The grass is always greener on the other side of time.)
