THN038 - S-132 (1) - Introduction - an add-on for the #IMSAI8080 Replica

The S-132 provides many I/O features of the IMSAI8080 normally provided by additional cards on the S-100 bus. It connects to the "Patch" header on the IMSAI8080 or Cromemco Z-1 replicas from @TheHighNibble (see: https://thehighnibble.com) And produces output on a VGA monitor with support for either a PS/2 or USB-HID keyboard.

Powered by an ESP32: S-100 + ESP32 = S-132

With the S-132 attached to the IMSAI8080 or Cromemco Z-1 replica you have all the functionality of the following S-100 attached devices, without the need to use the Web Desktop:
• VT100 (TTY:) terminal via serial UART (IMSAI SIO-2 S-100 card)
• two additional VT100 (or C3102) terminals (TTY2: \u0026 TTY3:) via serial UART (Cromemco TU-ART S-100 card - Cromemco Z-1 only)
• IMSAI VIO (CRT:) S-100 card
• Cromemco Dazzler S-100 card
• Cromemco D+7A Input/Output S-100 card
• two Cromemco JS-1 analog joysticks
• a Centronics parallel printer port (DB-25) via the D+7AIO with passthrough for the LPT: device

Additonally, the S-132 adds a System Menu (SYS:) where you can
• mount/eject disk images from the 4 emulated floppy disk drives
• view and control the Run/Stop/Reset/Ext.Clr state of the front panel (CPA:)
• view all the system information normally found in the SYS: device on the Web Desktop

Lastly, the S-132 has a DC barrel jack and a selectable 7805 5V regulator allowing you the option of powering your IMSAI8080, along with the S-132, from a standard DC power supply (from 5V to 12V).
