I will buy the A-0604 option when available.

I'm planning to buy a more powerful compute module when available, but wanted to start with the RPi compatible for the software (Wolfram, Mathematica, Dyalog APL). Be warned though that the CM3 module seems to draw down the batteries significantly after six hours of inactivity. This may be the result of breaking in a set of new 18650's, or just a lack of power management on the part of the O/S.

Finally tested the thermal printer today and it works quite well. You simply redirect text to a "file" in /tmp, linked to /dev/pts/2 and it appears on the printer. The printer handler runs in user space, not kernel. The printer interprets Eos/Pos command set so you can set font size, image darkness, etc. Someone even posted a Bash function to output a PDF file to the printer. The main problem I see is a lack of a tear bar. If you try to tear the paper you usually succeed in detaching the paper holder first. Best to use scissors instead.

The microHDMI connector and my adapter didn't make very good contact (HDMI device is detected at boot time and only then enabled). It was amusing though to see the usual boot messaging scroll right to left rather than bottom to top. Best to enable and stick with SSH or VNC.

Finally, here are a couple of pictures I did manage to take of the box content before assembly. There are two separate plastic containers with snap on lids to retain parts, one with the 3D printed parts and the other with the electronics.
       
Definitely not a box o' parts, but a well crafted carrier...

Postscript: Wine doesn't seem to run in the limited memory space of the CM3, so there goes my hope of running Emu71. Time to try J-F's DOS-based emulator.
