I'm looking for rare chips (processors, co-processors) listed in the
table below. In addition to them I'm looking for different kinds of processor
samples: engineering samples, customer samples, mechanical samples, thermal
samples and marketing samples (see the table below for more information).
If you happened to have one or more processors or co-processors from my
wanted list please contact me.
If you have any datasheets in electronic format, or if you have data
books for you no longer need them please check my list of wanted
datasheets.

samples |
| Engineering sample
| Usually marked "engineering sample", "eng sample",
"eng eval", "es", or "sample" on the
chip top, and sometimes on the chip bottom. Some Intel 80486 and Intel
Pentium processors are marked with "ES" on the bottom -
these are not samples unless there is an "ES" marking on
the top of the processor.
|
| Mechanical sample
| Marked "mech sample" or "mechanical sample".
|
| Customer sample
| Older Intel processors were stamped with "CS" on the top
of the chip. The "CS" letters usually differ from other
markings on the chip - they may have slightly different color and
font.
|
| Thermal sample
| Usually marked as "Thermal sample"
|
| Marketing sample
| The processors that look similar to pictures in press releases and
official product announcements. These usually have a nice looking
company logo and/or product (family) name. Marketing samples don't
have any specific information about the chip - speed, voltage, etc.
|
Please contact
me if you have chips from the list above, or if have samples of
any old microprocessors, microcontrollers or co-processors. |
