Found some "odd" 486 DX Cpu's.

Engineering Samples.... No sSpec, Q0123?




And without the SX or DX and with a "PR"?

Those seems to be eng. samples yes with that Q code! That 25 MHz are made 5 weeks before the earliest known 486 that we got here.

Think you'll find that your DX-33 E Simple has a Sspec of Q0128 not Q0123.(this might help you find it better). Wink
