32-bit Z8000 the Z80,000 and Z80320 Microprocessor

[Nathan Brown]

Looking for information about the old (Zilog) application note "Memory Management and the Z80,000 32-bit Microprocessor" (Zilog document number 00-2329-01).

I was googling "Z80320", as I do every few years, and found this.
comp.os.cpm is the "unofficial home" for conversations about obscure Zilog parts even when they're not running CP/M. (There is a Z8k CP/M freely available, inc. source. I tried to port the assembler to something sensible but failed.)
(I built a Z8001-based computer in the early '80s. I've got the 'Preliminary Z80,000 User Manual' (have you got that?) and a 'Z80,000 Electrical Specs' booklet, but no other Zilog Z80,000/Z320 documentation. I'd love to build a computer using one of them.)

- I have read the above message, but unfortunately google Gmail does not all for message read conformation when they are forward from a group/forum easily. Back in the old days with a paid service provided we could send a message acknowledge back to a Compuserv, AOL, Prodgy or etc email client host. (so they know their message was received and read). So anyways I will now thy to answer his questions without doing a bunch of retyping/re entering.

Yes I know about CP/M 8000 from the Z8000 microprocessor (the Olivetti l1m20 version of it).
Yes I have the same documentation as the Preliminary Z80,000 User Manual but I don't have any special
"Z80,000 Electrical Specs' booklet". The "Z80,000 Electrical Specs' booklet" might be interesting if it has the missing signal pins that Zilog omitted from their Z80K data sheets. As for the electrical requirements on the Z80K I just use the values from the hybrid version from Hitachi/NEC/Fujitsu OEM Components version.
..
On the more advanced clones of the Z80K from the OEM component sales dept. of :Hitachi, Fujitsu, NEC the chip is somewhat improved and had full backwards compatible with the 16-bit version. (unlike the Zilog version).
The 3rd party Fix chip (support IC) for the Z80320 and Z80,000 are not available.
..
As far as building a computer using one the CMOS version of the Z8001 and Z8002 is still available cheaply out of China, but the support MMU and other devices are not so freely available above 4 MHZ range. The Olivetti L1m20 computer is well
documented with firmware/software available to download. There were other systems with that processor but if you don't
have all disks, documentation or its semiconductor devices, I don't recommend trying to build one of them.
..
If you want a simple Hex based Z8002 DBC then check out https://store.shopping.yahoo.co.jp/orangepicoshop/pico-a-023.html
There are a couple of other Z8000 based SBC projects online - sorry data not handy - you will have to do an internet search.

I thank those who have replied.
Hopefully this entry will be read by some .
