Hi,
I saw an ACA1233 with FPU on Ebay and it is missing the additional oscillator. Is it not required and does the FPU run at same speed as the CPU (40 Mhz) then?
According to http://amiga.resource.cx/exp/aca1233 the FPU can run synchronous or asynchronous.
EDIT: After examining this picture https://www.ppa.pl/artykuly/pics/sekcje/sprzet/aca1233/20150129_234908.jpg I saw a solder bridge name 'FPU clk' on the right side of the FPU. I guess that when it's closed/shorted, the CPU clock signal (40 mhz) is used also for the FPU.
