- I have a surface mounted buster rev9 and 3.0 CPU card. I've been following
- these threads reasonably closely, and my conclusion is:
-
- 1. buster v11 & cpu 3.1 = no problem
- 2. buster v9 & cpu 3.0 = problem
-
- To fix said problem, you can either replace the 74FCT244 chip on the A4000
- motherboard beneath the CPU card with a 74FCT240 - although these appear to
- be difficult to source. Or, on the CPU card, you can lift pin 6 of the U200
- chip and short pads 6 & 7 of the U200 chip. Finally, you must set the
- "slow buster" jumper on the CV64.
-
- Note I haven't received my CV64 yet, but the above is based on reading a
- lot of these posts...
