Prototyping modules

[Steve Cousins]

I've added a couple of designs to my range of prototyping modules for RCBus, making my range now:

SC733 - Standard size module


SC711 - Large module


SC735 - Extra large module


SC736 - Extra large with two bus headers

The last one has two RCBus headers providing a 160 pin bus, shown here connected to two backplanes. Anyone want to build a 32 bit system with 32 bits of data and 32 bits of address?

Good alternative form factor for doing the buffered bus extender or for the dual port memory card between two systems perhaps.

Steve Cousins, referring to the new SC736 board.  And the Dual-Backplane for 

32-bit Machines.  Right what I have been trying to do, eventually  getting there. 

If  SC736 is the prototype board itself, when will the Part Number be for the 

Dual-Backplane ?? 

IMHO - The RCBus connectors - female sockets on the Backplane and  

the Male pins along the Bottom of the card - Much easier to work with 

as compared the the VME Bus. 

I look forward to the possibility of buying this new Double-Wide SC736

prototype card and the matching Motherboard /  Dual-Backplanes.
