 EOMA68 is a standard.  you may be referring to the first computer
card in the series, called the EOMA68-A20.

 done already. tested the armhf packages - they installed and worked
perfectly on an already-prepared debian/testing rootfs i had around.
the speed and startup time was impressive.

 i am considering deploying TDE on the 800-or-so cards going out on
the crowdsupply campaign.  if however qt5 or systemd is to become an
integral part of TDE i would reconsider that decision.  qt5 because it
so heavy compared to qt3 that i would be deeply concerned about it
over-burdening these low-power devices (qt3 is extremely
light-weight), and systemd because of both the resource
over-utilisation as well as the lack of accountability, security
risks, design flaws and the many other factors which are well-known
and do not need to be discussed further.

 the A20 processor has only a 32-bit memory interface (unlike x86
systems which often have 128-bit-wide data bus bandwidth to DDR3 and
in high-end systems have 256-bit-wide buses) and is only a dual-core
1ghz ARM Cortex A7.  TDE - *as it stands* - therefore boots up in a
reasonable amount of time, applications start up in a reasonable
amount of time, and KOffice is, for example, extremely useable.

TDE basically, because it has *NOT* quotes moved forward quotes, is
perfectly matched for the capacity and capabilities of low-power
systems.
