[comp.os.cpm] Z280 Ultraboard?

doug@hisata.UUCP (Doug Allison) (07/01/89)

A few years ago, I heard that High Tech Research was working on a 
Z280 board for the CP/M Kaypro.  The claims about it seemed pretty
grandiose, and I haven't heard anything about it since.

Does anybody know anything about this board?  Is it on the market?
Is it everything it was claimed to be???

Thanks!

Speaking of Z280's, there was an article on how to build your own '280
CPU board(S-100)...It's pretty simple, and uses only 16 TTL chips+'280.
So does anyone know of a source for the chip? I haven't found it in any
standard catalog(Jameco, JDR, DigiKey, etc...). IS it available, and if so,
how much? Thanks...

Mark

The article is in issue 2 of SuperMicro, pg 63.  At the end of the article
it says to call Zilog for information about the chip.
