 it's ok: right now the project is not targetted 100% at busy
average-use-case people.

 ok clarification:

 * 5 years ago the first version we paid USD 10,000 for them to fail
to fucking well listen.  i said the OUTER dimensions were 54 x 96,
sent them the datasheet with the part from china and expected them to
read it and communicate with me about the internal PCB dimensions
needed to fit into the casework.  luckily, when the PCB turned up and
was 54x96 mm in size, there were critical flaws which indicated that
the JUNIOR pcb engineer given the task had completely fucking well
failed to even run the Design Validation Checks.

 * 4.5 years ago the second version was handed over to a COMPETENT
engineer... we were ONLY charged USD 5,000 for this service.  i
decided that from this point onwards i would do the PCB layout myself.

 * 4 years ago the HDMI connector utilised on this second revision

 * 2 years ago the REPLACEMENT HDMI connector went END OF LIFE

 * 1 year ago yet *ANOTHER* replacement HDMI connector turned out not
to be available in reasonable quantities at reasonable prices.

 * 6 months ago the pressure on legacy TSSOP48 NAND (the A20 having a
BOOT ROM that only reads older NAND block sizes / speeds) became too
great and i went "fuck it, it's gone".

you do not know that you do not know.

 this is the latest development, yes.

 we don't know that yet.  it is *suspected* that that is the case.

 .... and be prepared to cover the *INCREASED* cost due to reduced
quantities but not a reduction in the fixed overheads associated with
component sourcing, supply, and PCB production *and* PCB assembly...

it could... if someone else is prepared to take responsibility for it.
i'll be absolutely honest: i'm getting tired of handling this stuff on
my own.
