 ===== Introduction =====
-The CPU280 is a single-board ECB-interface computer based on the [[https://en.wikipedia.org/wiki/Z280|]] microprocessor from Zilog, designed and originally manufactured by Tilmann Reh in the early 1990's. The CPU280 runs the in the Z-BUS mode with a 16-bit data bus. 512KB, 1MB, 2MB, or 4MB of dynamic RAM can be installed. The system boots to CP/M+ from EPROM. The CPU280 was one of the very few //hobbyist-buildable// CP/M computers ever made. RBC forum member [[227|fritzeflink]] maintains an archive of information about the CPU280 at his site [[http://oldcomputers.dyndns.org/public/pub/rechner/zilog/z280/index.html|http:%%//%%oldcomputers.dyndns.org/public/pub/rechner/zilog%%//%%index.html]].

 Late in 2016, RBC forum member [[193|lowen]] contacted Tilmann Reh and obtained permission to have a new run of boards made. Tilmann very graciously provided the manufacturing files as well as all necessary documentation and source code to rebuild the system, and [[193|lowen]] was able to get a beta run of ten boards made and distributed to several beta builders. RBC forum member [[92|Wayne W]] developed a build setup to rebuild the EPROM images and floppy disk images and set up a github at https://github.com/wwarthen/CPU280 for distribution and development. Several boards were successfully constructed using the beta run, and [[193|lowen]] had another ten boards fabricated. In spring 2018, another ten boards were run.

 ''%%Take care that in the 90s, there was no schematic editor in EAGLE. Instead, i just drew the schematic with the board editor. So now you need to edit both files to keep them synced. (I include the “schematic” file so you can update your documentation/PDF according to the patched PCB.) %%''
