Anyone interested should email me cluso -at- clusos.com
RamBlade is a double sided SMT pcb designed to run my OS and ZiCog/CPM/PropDos/Catalina/SphinxOS programs using the on-board 512Kx8 SRAM.
(Guess I should state it is essentially the best bits of the TriBlade Prop#2 which we are using for ZiCog)
