Questions for any Data I/O 29B experts

Archived from groups: rec.games.video.arcade.collecting (More info?)

I recently purachased on of these off ebay as unested. I have the Unipak 2
plugged into it and when it turns on it runs the self test without any
errors. It seems to respond to commands ok, goes into remote (CRC) mode,
etc. I built the serial cable as listed here:
http://www.leopardcats.com/dio/dataioserial.htm and tripple checked all my
serial port settings to make sure they match the programmer. I opened it up
to make sure everything was seated properly and everything looked fine...
except... The filter board (as it is labelled) has some burn marks on it.
Here are some pictures:

Here are my questions:
1. If this filter board was faulty would the data IO power up and respond to
commands?
2. Is it possible the filter board is working fine but has some char marks
from heat and maybe past repair?
3. Any tips on trying to get it to link with my computer (aside from check
your cable and check your port settings because I have done that many many
times on many computers)
4. Are there some other commands I can run to test the unit?

The problem was promlink could not communicate with my programmer.

Well, you solved my problem :-)
I was hitting <select><F1><start> and not the second start.

Alex,

Do you have a diagram of the serial cable between the D I/O 29B and the DB9 and my computer?

Thanks,
