TF536 Rev 2 Design Complete (all gone)
Posted: Fri Mar 20, 2020 11:01 am
Ok here is the list of changes on the rev2
1. Pull ups on A24-A31.
2. 68000 data bus is buffered with a 5V 74HC245 (like the TF534 design... to clean up voltage drop at the socket).
3. Generally more caps.
4. *ALL* passives moved to the bottom so they can be SMT Assembled by the boardhouse.
5. A new buffered/unbuffered design to allow buffering if desired.
I have ordered 10 of these. I'm going to build one to test.
I'm auto reserving for @8 Bit Dreams & @alenppc... who else wants to be on the list?
