Some nice results in the 2nd video. I'm sure they'll improve the Ethernet in due course & implement speed enhancements across the whole board as time progresses.

Had no time yesterday as work interfered with my Amiga time. MYiR board also arrived from Mouser. I put in for a board after Wranglers video. My bank account is much lighter after his AA3000+/BFG/3660…. videos… |

It looks like a great card, the dual CPU design is simply genius, it not only addresses the problem of 060 shortages, but also considerate to those users who still want to use the 060, with users having the option of either one, or the ability to switch between both.
I can't wait to see how this project matures, any plans for EU/UK builders to come onboard? |

Please forgive the possibly stupid question but will this work on an A3000 '030 25MHz with RAMSEY4 and DMAC2? Or, will I need a RAMSEY7 and DMAC4?

Should I be concerned?
I don't want to fry my newly acquired 060.
5V and 3.3V measurement at power on (Z3660), attached pic. Code:
11.2.1.2 INPUT SIGNALS DURING POWER-UP REQUIREMENT. The second issue involves the requirement that during power-up, input signals to the MC68060 not exceed Vdd by more than 4 V. This is achieved by ensuring that the 5-V supply not exceed the 3.3-V supply by more than 4 V. In any of the previously discussed DC-to-DC conversion solutions, it is possible to add three diodes in series from the 5-V supply to the 3.3-V plane. During power-up, the diodes forward bias and thus provide a current path between the 5-V source and the 3.3-V plane. This solution provides no more than (0.7 * 3) = 2.1 V drop between the 5-V input and the 3.3-V plane. When the voltage regulator stabilizes, the difference of (5 – 3.3) = 1.7 V is insufficient to forward bias the three diodes, hence not dissipating any energy. Both Motorola and Linear Technologies have indicated that the three diode shunt does not adversely affect operation. |
