It truly was amazing to read the development given the lack of documentation available (15-year old proprietary chips of a dead company, etc), and set a high watermark of hardware development and testing for the classic Amiga platform. My hat remains off to you to this day.
Put your hat back on :-)
The most amazing thing was to find a bug (believed to be killed from Rev9 to Rev11 changes) in the last Buster Rev11. Personally, doing the DENEB development gave me quite some experiences on designing in a hostile environment, so to say.
Even the developer group from phase5 seems to have stumbled on some Buster Rev11 issues while doing the FastLane Z3, but they couldn't solve the problem... the DENEB V11 firmware does fix that Buster bug in "hardware" and allows operating Zorro III RAM next to one (1) DMA master finally in a stable way.
That was the most surprising issue... even the schematics published in the patent stuff for Zorro III seem to reflect that problem :-)
As stated already, I'm open for licensing the hardware design to some guy willing to invest money on production and product service. Anyhow, this guy should better check first if he is priviledged enough to acquire the Poseidon licences needed for legally selling the cards he has spent his money on in advance, and on his own full risk.
