Chips (nicht zum Mampfen)

Ich habe hier was für Sammler:

80C186 und 80C188 Embedded Prozesoren, aus Videosignalplatinen entnommen, funktionierten noch.

80287 Coprozessor in der seltenen und schönen Gold-Version

Preis VB oder auch gerne Tausch gegen Retro Audio-Signalchips ... schaun mer mal

Stimmt, kurzer prägnanter Auszug aus einer Diskussion:

Zitat

- XL processor is almost twice as fast when executing basic arithmetic instructions (add, sub, mul, div).
- other instructions, such as load, store, special, etc, could be slower or faster depending on the instruction, operand type, etc, but on average they have comparable execution time to 80287.
- The 80287XL divides external frequency by 2, while the 80287 divides it by 3. Because of this, when the XL processor is plugged into 80287 socket, it will run at 50% higher frequency than the 80287.
- The XL has a few additional 80387 instructions - sin, cos, etc.
