About a month ago I received an email that said this:
------------------------------------------------------------------
From my experience on using the ispLSI, I doubt that the isp1048
can implement any kind of CPU.
I guess that the MiniForth is running on i8032 CPU. Am I right?
------------------------------------------------------------------

This is a common belief, that it is impossible to implement a processor
on the Lattice isp1048 PLD. Typically this assertion is followed by
the unbeliever explaining that he tried to do so, but that turkey didn't fly.
Having a job interviewer believe that I'm telling a tall tale means that
I won't get the job!

I think that Tom Hart and John Hart were fools to refuse to admit
that I wrote MFX for the MiniForth, saying that I am lying about this
and that I was never anything more than a maintenance programmer for
MFX that was written by John Hart and Steve Brault before I showed up.

When people say that the MiniForth was impossible due to the
Lattice isp1048 PLD being too limited to support a processor,
there are only two witnesses to the development of the MiniForth
who can attest that the MiniForth was successfully built.
These two witnesses are myself and Steve Brault.
When Testra accuses me of lying about writing MFX, Testra undermines
my credibility in attesting that the MiniForth was successfully built.
This leaves only Steve Brault to attest to the existence of the MiniForth.

Steve Brault seems to be quite absent in this thread attacking me.
If he were a loyal Testra employee he would have joined in on Tom Hart's
attack on me, to prove his loyalty to Tom Hart (and keep his job).
He hasn't done so. This presumably means that he quit Testra sometime
after I quit Testra, likely for the same reason (low pay, although he was
likely making two or three times what I made). This means that there are
no witnesses remaining to attest that the MiniForth actually existed.
This is why people feel comfortable in saying that the MiniForth
was not a processor but was just an i8032 program --- there is nobody
to contradict this accusation that the MiniForth is a tall tale.

It is all in the thread I started at the time to clarify what happened,
and many people gave their opinion.
https://groups.google.com/g/comp.lang.forth/c/wydQr643gX0

If this went through to production, many many customers would own it now.

Please dump your shit elsewhere.
