System 816

The Compupro 8/16 system was one of the last, big, expensive CP/M system that appeared at the end of the S-100 Bus and 8-bit professional systems era.

It was actually a typical S-100 box where the user could insert almost any S-100 card build by the manufacturer or anybody else.

As Compupro manufactured a large range of S-100 card, the system could be fitted with either 8-bit and/or 16-bit processor cards. One of the best-selling card was a dual processor 8088 + 8085 that allowed running both 8 bit CP/M and 16 bit MP/M software, at a speed of 2 or 5 Mhz, in a multi-user, multi-tasking environment.

Several advanced CPU cards were available later: Z80 at 8 Mhz, Intel 80286 and National Semiconductor 16032.

Due to the large range of available CPU cards, practically all operating systems and programming languages of the time could be used.

It appears that Compupro still exists and offers a limited support, spare parts and manual hard copies.

Please consider donating your old computer / videogame system to or one of our partners from anywhere in the world (Europe, America, Asia, etc.).


I have a complete CompuPro 8/16 system that I would like to sell. I do not know if this is the proper forum for this. This belonged to my father and I am in the process of settling his estate. I have posted pictures of the system components. If anyone has any interest or advice on how to proceed, please feel free to contact me.

I''m soon going to be working on the system, and will be doing upgrades to it as well. If everything goes well, I hope to start making videos online. I want to see if i can make a old computer do new tricks. as well as teach people 74 series logic. I hope to reach out to someone that may be willing to donate parts for this. I want to make a all original and one that is fully upgraded. I want to start with this system first because, not many people know what this pc is.

If you are interested in getting rid of your Compupro Components, I would be interested in having them.

I don''t know if this is allowed on this Forum, but I''ll post my email address for you to contact me.
