ProtoCache1.1 - IIsi/SE/30 PowerCache Adapter Prototype

I was working on cloning the MacCon and had this funny idea:

Why build a MacCon in original form factor that needs another adapter plugged on top of it if you can make it just one big thing and safe a few bucks on useless connectors?

Curious if this will work.

This looks very interesting.  I had pondered if something like the 10/100 board someone here developed (I think Mac to the Future).  It would be nice and not terrible to integrate both.  Though I wonder if something likes @ants did could be integrated with WiFi.  That would bypass the need for other stuff

Very cool, you also save on capacitance added by the connectors, making the assembly more stable for supporting PowerCache and passthru stack.

That’s true as he designed it is very optimized to have the most functions.

@Trash80toHP_Mini  I missed the bump.  Sorry.

How many pins is this one?  I always get them confused with the LC PDS and the NuBUS.

Bumpage was Bolle's exciting announcement his project: equipping his tall naked DiiMO form factor ProtCache Adapter with the addition of a MacCon clone in the blank real estate on the PCB.

Going from memory in a hurry during lunch: LC PDS is 96-pins, same connectors used for NuBus. IIRC the LCIII moved to a 120 pin interface (same as 030 PDS Connector) with at least a couple of rows of pins missing for the two part connector extension setup. ISTR the Quadra 630 PDS moved on to a full 120-pin implementation, but most LC cards were missing the 'gate" at the extension end of the connector by then, so they work fine in the longer full 120-pin implementation of the Q630 series pin compatible with the original LC PDS.

Are you using the same components the maccon uses? And you still need the smaller board that you plug in ethernet, right?

Yes, mostly the same components. The bipolar ROM will be replaced by a normal flashrom but other than that it will be the same.

I was planning to just wire up an AUI port to the breakout box connector on the card and use an external transceiver. (or use the standard Asante breakout - for some reason I have more breakout boards than ethernet cards)
