TF536 Rev 2 Design Complete (all gone)

Post by terriblefire »

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?

Looking good, would love to build one, but I am new here and I do not mind waiting if other older members want to get in first.
Happy either way. :)

This looks amazing!
Will build it with buffered ide, and let it run in an A2000 :P :D

Just one question:
What about CDTV support? Is it planned for that card or rather not because of DMA issues we met on rev.1?

PS
Ordered 50x 68030 CPU sockets and 20x genuine 40Mhz EC CPUs from US, so let the Terrible Fire out!!! :P

This needs someone to spend time to update the cdtv driver to use non 32 bit fastmem for the DMA buffer. I uploaded a resourced version of the code if anyone wants to take that a bit further.
