    I have question

    I have ACA1233N 26mhz and I want to put faster CPU 40mhz or 50mhz

    If I takeout this 68030 26mhz and I solder new 68030 40mhz or 50mhz

    Ofcourse I swap crystal as well

    card I'll be work ?

    Any body done this swap ?

    No need to swap the Xtal; both the 26MHz and the 40MHz card use an 80MHz crystal. The CPU swap won't get you far; it will run at the exact same speed.


    You can buy an updated CPLD for the difference in price of the two cards. That means: You ship the card to us with the new CPU on, we do the re-programming of the CPLD to 40MHz for 80,- EUR incl. VAT, take note that the card is out of warranty, and you have a 40MHz card. Might be cheaper to buy the real thing in the first place :-)
