Building a HP35 scientific calculator clone
It's nice to present this project - Building a HP35 scientific calculator clone with a Z80 cpu from scratch.

[Image: 1_25.jpg]

But without using emulators, HP microcode etc. I have always wanted to rewrite original algorithms, created by David S. Cochran.
As the original HP35 was built 50 years ago, this is a good time to do the same :-)

Everything (hardware, software, source code, working gerbers etc) is on my github page:

https://github.com/olekgr/HP-35_Z80

I hope this project will be interesting for someone.
