To check if you have a CPLD take a look at this video (10min10sec). It's an altera MAX II.
About bandwidth upgrade, my earlier tests were wrong.
After upgrading again, I could notice that filtervu shows me 200MHz max value instead of 100MHz before, and time\dv decrease to 2ns instead of 4ns before. So I really think there is a chance that have worked.
I really would like to test it with a signal generator to check 3db frequency.

I have a MSO 2024B and I could do it for you. 8)
Please tell me exactly where I have to attach the RS232 level converter.
I read "MPC870 U13(SMTX) and T12(SMRX) pins are routed to B23 and B25 pins on external connector", but I'm too lazy to actually find them. ;D
luisprata:
Look at expansion, you can put some small rigid wires into connector.
They are 8th and 10th positions counting as shown in figure.
Update: **** Please check voltage on TX and RX pins before connect...
drsurfer:
Luis, I did the connections according your picture.
I've verified that the markings on PCB match with your previous post, B25=RX (input) and B23=TX (output).
I've connected GND to the matching pin on the other side, A23.
No significant voltage at pins: on TX I would have expected to see 3.3V or similar.
Then I've connected the TX pin (B23) and ground to my to USB 3V3 converter;
I'm afraid to connect my converter output pin until I'm sure I'm doing right... :-[
No activity on terminal. :(
Should I send some char to trigger the boot log start?
At what baud rate should happen the communication ? (later) Ok, I've read on your posted log 115200 bps.
