wanted v20 cpu

I have one here that's been waiting a long time for another member to send me a mailing address.

It's untested, but hey, it's free and it's sitting in an anti-static tube inside a bubble mailer.

PM me an address and I'll ship it to you instead.
 
If that didn't work for you I found one while searching for 68xx parts for another member. Its a good pull.
 
Z80

Z80

I think you're thinking of a different one. Hitachi used to make a replacement/more features one, but I'm drawing a blank as to the part number.

I just found the Z80382, which looks really interesting, here:

http://www.z80.info/z80382bd.htm

I was thinking of making this work inside a Genesis, and drop pcmcia into it since the capability is there for it. I dunno, maybe I'm over tired. Seems really workable to me right now.

And I think I remember the v20 replaces the 8088. I think.
 
Something came up today. Can the V20 replace a Z80?? Or is that a different processor that I'm thinking of?

The V20/V30 has an 8080 emulation mode, but not the Z80 instruction set.

By "replace", exactly what do you mean? AFAIK, the Z80 is the only chip that's pin-compatible with the Z80. As far as the instruction set, there are a bunch of other candidates, such as the Z180/280/380/EZ80, NSC800, and even the "Z80-ish" Rabbit R3000, not to mention various implementations in FPGA.
 
I believe some of the Amstrad / Schneider XT class desktops used the v20 and v30 processors. I have a PC 1512 that is complete but won't read from the 5 1/4 floppy. It has the V30 processor installed.
 
The guy with the V30 page has a strange idea of the availability of 8080 software out there. CP/M-80 and a ton of application software and languages, such as WordStar, SuperCalc, Multiplan, Microsoft FORTRAN and BASIC, DRI's PL/I, CBASIC,....

I think it would be fair to say that there's more software that will run on the 8080 than there is software that's Z80-specific.

There are many chips that include the Z80 instruction set, for example the ATJ2085 or KL5C80A12.
