The Elusive Intel P80C85

[gmphillips]

Has anyone actually seen one of these? They were supposed to have been used in one of Tandy's early portable computers.

I have also seen a reference to an 80C85-6 (6 Mhz) part.

Netcomponents show 0 worldwide inventory on any P80C85.

Does anyone know why these chips are so rare? Does anyone have
an Intel datasheet for it?

Thanks,

George

Are you sure these chips built into tandy portables really were Intel parts? There are a lot of second-sourced 8085s around which you'll be able to find from time to time, e.g. like this Mitsubishi version of a P80C85A-2:

I never heard about Intel 80C85 before. Google shows only one Chinese site that has Intel P80C85 in stock:

I also found multiple references to the chip on the net.

Try the following Google Search:

+"Intel 80C85"

and you'll get hundreds of hits.

If you wonder why it's taking years for me to write my collectors guide
for vintage Intel microchips, this is a perfect example:)

On an unrelated subject, thank you for teaching me how to search for an exact phrase in Google

I just did a search on Netcomponents and it shows 35 Intel P80C85 plus datasheet, but I am 99.9% positive that the 35 Intel P80C85's on Netcomponents are the same 35 Intel P80C85's on the Chinese site.

When I searched for Intel 80C85 I noticed many web pages mention that TRS-80 model 100 has this processor. Well, now I'm a happy owner of TRS-80 model 100 computer:



Sadly, the computer doesn't have Intel 80C85 processor. Instead, it has OKI 80C85. Memory chips on a system board look very nice. The picture of the board:

Of course, this is not a proof that Intel 80C85 does not exist, but is it possible that people mean "80C85 compatible with Intel 8085" when they say "Intel 80C85"?

This is a better example of using mythical Intel 80C85
