Hi Steve, i'm located in Germany, an i was responsible for INTEL from 1980 to 1986 at an Distributor. I found your ISIS-II stuff, when i'm looking for an CrossAsm for Mostek MK3870. If you need something i've a lot of original INTEL Software for ISIS-II and ISIS-III, and also Literature - feel free to ask me I read you have disassembled ISIS-II, - i'm interested in the source code. Also i'm looking for an XASM running on ISIS-II for MOSTEK MK3870 an Single Chip Controller based on the FAIRCHILD F8. Greetings from Germany Walter
