Attention: Al Kossow See url: http://www.classiccmp.org/pipermail/cctalk/2004-January/035417.html You discussed options with TMS1000. Have you found a way to read the rom as yet. There is : http://www.google.com/patents?vid=USPAT3988604&id=Py4uAAAAEBAJ&dq=3… in the PDF it explains using the 'test mode' to dump rom. Is this of use ? Beyond my capability. Would appreciate your comments. charlie at tech-j.biz Charlie Harris New Zealand
