Interesting... is that the same ECU connector as 90's Mitsubishi/Toyota? Denso OEM ECU case?

Yes, same 64 pin connector as 90's Mitsubishi/Toyota/Honda/Mazda. Yep, Denso OEM case from a Mazda 323/Protege/Miata.

Second batch of assembled version 0.4 has arrived. Note larger proto area and two extra low current drivers.

New batch of same exact Frankenso 0.4 has arrived - boards are back in stock.
