Had one for a few years. Never plugged it in, had forgotten what it was for.


I still make them to order (February 2017)

Current pricing (Feb 2017) - subject to change

   RamBlade US$30.00
   microSD Card Optional US$9.00 (SanDisk 8GB with my OS and ZiCog + CPM2.2 installed)
   Shipping US$4.00 unregistered post

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)
