Got your email from above group.
I use a TMS1000 in a model railroad contgroller from the late 1970s called Hornby Zero One.
Do you knlow if anyone has been able to dump ram easily via the test mode ?
I would like this to be done and then make a small change, allowing more addresses available (16 now, need say 64) and place on 8-bit modern processor.
Your comments would be appreciated.
