I want to apologize about the misinformation I posted about the V20. The V20 is indeed manufactured by NEC, and until now I beleived it to be manufactured by Zilog because of the Z80 emulation mode. It is also a direct replacement of the 8088, which is the 8 bit bus version of the 16 bit 8086. (excuse mode on) It was late.

Actually, this article (apologising for misinformation) contains some more.
The V20 contains 8080 emulation; NOT z80 emulation!!!

There's no Z80 emulation, of course. Just good old 8080. If there was a V30 with Z80 mode it'd be in my 6300 so fast . . . Meanwhile the V30 with 8087 work like a charm giving me the 80186/80286 instructions, faster indirect memory references and less power drain (the V20/V30 are CMOS). -- Bill Pechter -- Home - 103 Governors Road, Lakewood, NJ 08701 (201)370-0709 Work -- Concurrent Computer Corp., 2 Crescent Pl, MS 172, Oceanport,NJ 07757 Phone -- (201)870-4780 Usenet . . . rutgers!pedsga!tsdiag!scr1!pechter ** Why is it called software when it's so hard to install.

I don't know ) Zilog built the V20 and V30, presumably under an alternate sourcing arrangement with NEC. I have in front of me two "Preliminary Product Specification" booklets from Zilog summarizing the Z70108 V20 and the the Z70116 V30 devices, both dated May, 1986. Contact your friendly neighbourhood Zilog person for details. jeff ---- -- Jeff Cole 360 Tapscott Rd. Perle Systems Limited Scarborough, Ont.
