CT60 and related things BBS
Re: CT60 not found

Okay, thanks for the tip, Instream.
I checked the pins on the CT60 expansion headers using oscilloscope.
I can see the clock as well as activity on the address bus.
However, all data lines are static at +5V.
I'm not sure if this is normal.
So, this seems to indicate that the connection to motherboard is there, since I do have a voltage.

Could you think of any other test points to try on the ct60 board?
On the ABE for example?

Also, how does ct60flash.tos determine whether or not ct60 is present.
I may write code to check the contents of the flash, since it should appear in memory at $e00000 (same as TOS ROM) according to the ct60 harware guide.

Thanks again.

Message board and comments are now read-only

Due to abuse of the message boards we have put the entire site in read-only mode. That means you can't post new threads or reply to old messages and you can't add comments in VideoDB and PicDB.

Some messages have been erased from reading, but are stored in case they need to surface again.

After 17 years and 45000 messages we're shutting down due to one person.
