# Configuration (Draft)

The S-132 requires only minimal configuration to get working.

The majority of features require no configuration to make work. However, the boot.conf file on the IMSAI8080 or Cromemco Z-1 replica must be edited to enable the TTY: (TTY2: & TTY3: - Cromemco Z-1 only) and VIO: keyboard (IMSAI8080 only) to be recognized as input/output devices by the HAL in the IMSAI8080 or the HAL in the Cromemco Z-1 respectively.

The VT100 terminal emulation (VT132), on the other hand, has extensive configuration options. See the VT132 Operation Manual for details.

# Start-up

With the S-132 connected to the IMSAI8080 or Cromemco Z-1 replica along with a VGA monitor and suitable keyboard, apply power and press the hardware reset on the IMSAI8080 or Cromemco Z-1 replica. As the replica boots it will force the S-132 to reboot.

The S-132 will perform a hand-shake with the ESP32-PICO-KIT on the replica and you will (may) briefly see the message

Host found

displayed in the upper left-hand corner of your VGA monitor. This will rapidly be replaced with the message

Wait

and a brief bell tone from the buzzer while the VT100 terminal initializes and retrieves its setting from the NVRAM.

# Power Options

The S-132 can be powered from the connected IMSAI8080 or Cromemco Z-1 replica. Additional power is not required.

Alteratively, the S-132 can provide power to the connected IMSAI8080 or Cromemco Z-1 replica if you connect a DC power supply via the DC barrel jack on the S-132. In which case you should remove any USB cable providing power to the connected IMSAI8080 or Cromemco Z-1 replica.

# Configure the IMSAI8080

You must edit the HAL settings in the boot.conf file. You can use the Web Desktop, or mount the µSD card in a PC and edit the /imsai/conf/boot.conf file directly.

Enable and initialize the S-132

### Enable S-132
S132.init=1

To make the S-132 the first (and only) preference for the TTY: and VIO: devices, use:

### SIO-2 default port mappings (HAL)
SIO1.portA.device=S132TTY,WEBTTY,UART0
SIO1.portB.device=S132VIO,VIOKBD

To make the S-132 the first preference for the TTY: & VIO: devices and also simultaneously use the Web Desktop devices if connected, use:

### SIO-2 default port mappings (HAL)
SIO1.portA.device=S132TTY+,WEBTTY,UART0
SIO1.portB.device=S132VIO+,VIOKBD

To allow the Web Desktop to capture the TTY: and VIO: devices with priority ove the S-132, use:

### SIO-2 default port mappings (HAL)
SIO1.portA.device=WEBTTY,S132TTY,UART0
SIO1.portB.device=VIOKBD,S132VIO

For more information on the boot.conf see HAL configuration for the IMSAI8080

# Configure the Cromemco Z-1

You must edit the HAL settings in the boot.conf file. You can use the Web Desktop, or mount the µSD card in a PC and edit the /cromemco/conf/boot.conf file directly.

Enable and initialize the S-132

### Enable S-132
S132.init=1

To make the S-132 the first (and only) preference for the TTY: devices, use:

### TU-ART default device mappings (HAL)
TUART0.deviceA.device=S132TTY,WEBTTY,MODEM,UART0
TUART1.deviceA.device=S132TTY2,WEBTTY2,SCKTSRV1,UART1
TUART1.deviceB.device=S132TTY3,WEBTTY3,SCKTSRV2,UART2

To make the S-132 the first preference for the TTY: devices and also simultaneously use the Web Desktop devices if connected, use:

### TU-ART default device mappings (HAL)
TUART0.deviceA.device=S132TTY+,WEBTTY,MODEM,UART0
TUART1.deviceA.device=S132TTY2+,WEBTTY2,SCKTSRV1,UART1
TUART1.deviceB.device=S132TTY3+,WEBTTY3,SCKTSRV2,UART2

To allow the Web Desktop to capture the TTY: devices with priority ove the S-132, use:

### TU-ART default device mappings (HAL)
TUART0.deviceA.device=WEBTTY,S132TTY,MODEM,UART0
TUART1.deviceA.device=WEBTTY2,S132TTY2,SCKTSRV1,UART1
TUART1.deviceB.device=WEBTTY3,S132TTY3,SCKTSRV2,UART2
