Latest update

Project source code (latest snapshot including MINC):

Major changes in this version: Most obviously, this is the first release that includes MINC – look for the sources called mncXX, where XX is the name of the module. There are ADC drivers for the DE0-Nano and DE10-Lite boards, and MNCAA can be connected to a PMODDA2 for analog output.

Also, I’ve moved to Quartus 20 (and fixed an issue that comes with Q20). And cleaned up the source tree – a lot of old and no longer useful files have been removed.

Previous update

Project source code (latest snapshot before MINC):

New in this version: a number of new build directories for the CYC1000 board – look under cons-c1k-(rk|rl|rh|rhxu). Those directories also contain bitstream files for that build, both in SOF and in JIC form.

There are also a few minor changes for CYC1000 that should improve stability; for instance I’ve added pull-up resistors for inputs that may not be connected.

F-11 cpu support (11/23 and 11/24) has also been improved.


The gerber files for the shim board to connect CYC1000 to a PiDP-11 console (see CYC1000 page for more info):

The gerbers are according to Seeed’s design and cam job rules. I’m not sure if they work for other vendors – please check, and let me know if you need a different format.

Disk image

For convenience, I’m putting up my base image of 2.11BSD here. It’s installed according to the page under the HOWTO section, and patches have been applied up to #469.
