ColorCNC Colorlight 5A-75E/5A-75B as FPGA controller board

Firmware for 5a-75e board
Compared to 5A-75B: added 6 encoders (total 6), 20 DO (total 32), 6 DI (total 30), 3 PWM (total 6). This version will be tested in hardware as soon as i'll get the board
For safe operation under disconnect condition, a little modification - reset of all pins to predefined state - is needed

Quick question, I've gone through the process of installing
arachne-pnr
icestorm
nextpnr
prjtrellis
yosys
and the Litex stuff, all from git and after running colorlight_5a_75e.py and build_colorlight_5a_75e.sh (which completes without error) the bit file comes in at 610185 bytes compared to 626411 bytes from your archive. Any idea of what may cause this ?

Or is the latest OSS CAD Suite the tools to use ?

This sounds very interesting.

How do these cards compare to a Mesa 7i76e? Looks like the 7i76 has pins tolerant of higher voltages 24V+ and the these colorlight are 5v tolerant (and anything more would need external components)?

Would one of the colorlight boards be comparable to a Mesa 7i98?

(I'm a big fan of Mesa boards and have a couple. Peter gives amazing support on this forum  But here in Australia price of shipping means MESA price goes up a lot. <AUD$40 delivered for a Colorlight E board versus AUD$245 for a 7i98 delivered)

A generic Parallel BoB would work, I have some boards left over from the BeagleBone that I can use. But yeah it's a bit exy getting stuff sent to Aus. Doesn't matter what it is really. I just grabbed a colorlight and yep under 40 beer tokens delivered. I have 5 MESA boards for the Mill....I could have got away with just a 7i92 & 7i76, but I went a bit OTT.
