Do you have a working 68K core with all the support chips? What would convince you to release that so that efforts could be made to port that to inexpensive dev kits? I know this runs contrary to the current QL culture of charging for every little thing, but if a semi working core were made available, I'd be interested in putting what little expertise I have to help finish it. But only on commodity hardware now that it's becoming ubiquitous (e.g. arcadefpga) _______________________________________________ QL-Users Mailing List http://www.q-v-d.demon.co.uk/smsqe.htm
