Prototyping board?

[willjlong]

I can't locate documentation on prototyping board. I'd like to conjure up some simple external "peripherals" such as LEDs and switches.

The S-132 provides a protoboard and some basic I/O capability.

The Cromemco D+7A Input/Output card emulation contains some physical I/O.

I saw the overview link. I'm looking for specifics as to how the prototyping board is used in conjunction with IMSAI.
Thanks,
Bill

You'll find the pinouts at:

You'll find port info etc. here for programming against, see Table 4 Port Assignments

Remember that the emulated version is a subset of the original, it doesn't implement all the D/As / A/Ds and digital I/O bits due to limitations of the ESP32 doing the emulation. I don't recall the details, but it's covered in the first link. I've been able to program it using BDSC C and assembly.
It looks like the web page for it doesn't have the setup menu options to set the emulation in various modes. There are some notes here:

The setup menus allow you to enable/disable and configure the D+7A to various modes. My IMSAI and S-132 still need to be unpacked so I don't have a working one to document the setup.
I have example C code I wrote but I can't access it until I get my IMSAI set back up.

Thanks. I'll get to digging...
