I'm taking a second run at explaining what the "Agena Shield" does.
I've illustrated a dual purpose combination SMT Pad/Thruhole footprint that allows either type PLCC Socket to be installed (hopefully) on Prototype or the QFP 68030 Agena Shield.
A DIP strip socket/tall header board interconnect system for mounting Shield to Prototype also provides headers for attaching leads of Logic Analyzer. Same for the BGA socket/tall header setup, the headers plugged into the PGA 68030 Socket correspond 1:1 (crosses fingers) with the pads of the QFP 68030.
A nice overhead shot of the SMT Socket with a size reference floated to the surface of the 'Bay, so I dragged it on board. Gotta find a nice Pic of the PGA socket, that gradient thing was an accident I left alone.
Does anyone have a link to a
REAL PostScript PDF data sheet for the QFP 68030? I need to snag the outlines and text for use in AI. Same for the PGA IC pinout. I HATE scanned in paper page images, they're awful.
Unifying the Killy Klip/68000 leg interface with a Right Angle SE PDS Connector installed puts Agena vertical for easy probing The "NuBus" type connector is far more robust with additional power/ground lines, buffering and some strange voltages and clocks thrown in there too!
The cutout necessary for SIMM Socket clearance make use of the setup in the horizontal impractical. It's gonna be open air testing on the bench for a while.
That's the plan anyway. I've got two more pages to go in the GAL Coloring Book and a bit of GAL rearranging in the AI file to relax between connection buzzing sessions. I'm running on empty ATM, but I've got three days to rest up at work! [
