I do agree but unfortunately the same 16 k size does not seem to work on Colibri T20 despite using the exact same ASIX USB to Ethernet chip. I tried to pinpoint the exact reason behind this but so far could not figure it out. I fear it has something to do with this Gizmo/bus arbitration stuff on T20 which has been fixed/improved on T30. Would be interesting to try on a Trimslice but unfortunately we never got our iron back from service.
