Looking for complete project information from : https://z8000.neocities.org as it is no longer available at this email address.
If anybody reading this still has those files, you can please reply. Thanks'.

Requesting a copy should not be a problem. As trying to post a new forum under the google forms just seams to violate their terms, we see if any readers of this message has them archived.

Thank's.
 
Rather not. As one can see from the URL it's a Z8000-based project, which is a very different architecture. Apparently the Z16C04 is equivalent ("core compatible") to the Z16C01 except being faster (16MHz vs. 10MHz). See the page in https://archive.org/details/Zilog-ShortformCatalog1991OCR

https://z8000.neocities.org/z16c04.html used to start "The Zilog Z16C04 is a 16MHz CMOS version of the Zilog Z8001 produced for military markets. It's a pin compatible replacement of the Z8001 in PLCC68 package ..." according to Google Search.

According to https://www.kranenborg.org/z8000/ "the Z16C01 as the equivalent of Z8001".

I'd be interested in seeing more about that project as well.
 
I thank you for your reply, but that is not quite what I am looking for. It is quite different even from the old Zilog Data communications development board part # Z16C0100ZCO, which used the Z8000 microprocessor family. The project that was originally posted at https://z8000.neocities.org could of been based of it. But without any hardware I/O Addressing details, I can't be sure of that. Their is no current contact information on anybody who ported a more advance Z8070 FPU to PLAs. The project at ....neocites.org was likely based of the Hitachi Hd68LT8881 FPU. No serving data on that semiconductor either. It was a more advanced FPU them the MC68881 which had emulations for other FPU on board.

I am already aware of the Z16xxx family of components, including the military version of the Z16C04 that is still being produced by Honeywell. Still thanks' for replying.
Unfortunately attaching a copy of the Z16C0100ZCO sales Ad in PDF format is too large for this (VCF.org) server to process at around 2M in size.
 
But it's a closely-related thing :->. Just pointing out a proven SBC design in case anyone passes by and thinks "gee, maybe I want to try out a Z8000" as a new hobby project. Not everyone will want to jump into the deep end of the Z8000-pool with segmented memory on their first outing (assuming that they can even find the necessary parts). And then there's the general issue of software-lack given market failure. One challenge at a time ...
 
Olivetti made a Z8000 based computer. They ran PCOS and CP/M - ported over in C - as an operating system. That means there is a native assembler and at least a C compiler available for it.

Although this requires the use of a Z8001 and not a Z8002.

It sure is...


Some of the documentation is available only in Italian though...

Even the source code (along with the binary disk image and documentation) for CP/M-8000 is available from here:

Anyone know what happened to the software for the Z8000 from the AMD-Siemens venture (AMC)? I was asked if I was interested in doing the software for their development system's EPROM burner; I submitted a detailed proposal with design. The ijits turned me down but used my design to implement said software. I was more than a little peeved!
 
Z16C0100ZCO Product Specification one-pager attached. Thanks for pointing out the GLU; don't know about that.
Thank you for uploading another copy of it, for some reason my newer PDf version of the file is around 2M for 1 page of data, So it excided this host limited.
 
Would that fit in with a copywrite violation?
As far as a copywrite violation/patent infringements it really depends if they have expired and where not renewed. In most other countries after 25 years of none renew its fair game.

Interesting but Siemens did do a couple of Z8000 based control boards, but nothing else externally. As with your detailed proposal and design , if it was copywrite or patented before it was submitted to them, them you could try to get your development cost back. But the legal fees' might exceed its cost. I have had been through hostile takeovers (for product suppression) so I can relate to that.

Cool somebody noted a Olivetti L1M20, I have several Olivetti l1 family members still in active service outside of North America for work. As far as Z80ne.com in the past I have sent them the details on the L1M20 revisions G and H motherboards, but it never got posted at the web sight. Some newer revisions of the motherboard supported more than 512K of memory on board.
 
Yes (https://en.wikipedia.org/wiki/Olivetti_M20) but is any of this software and system documentation publicly available?

Segmented memory and CP/M in the same breath :-}!
Yes the main documents are available at a couple of websites. http://www.z80ne.com/m20/.... (some Bootdisks,Manuals) . Bitsavers.org computer archive section has the Olivetti_M21_M24_Theory_of_Operation_Nov84.pdf
Other they the MMU PLA, the rest on this machine is standard to get logic chips. The optional FPU modules are another story tho. See the above manual for the I/O address for IBM PC Intel based peripherals on the M24 PC.

For those of you that are replying, Thanks. I currently don't have the time or resources to as the old saying goes "to re develop the wheel" then rewrite drivers for it. So I was looking for a newer design that could be easy updated. There where several Z8000 based SBC that had the slow to load Intel/AMD 8231 or 8232 FPU's on board that I not really interested in either, so I note it now (to save us time). AMD part # was 9511 and 9512.
