- SD_CARD_X49 mounted on CARRIER95TO49MM
- JOYPAD
Connectors
H1 - I2C Interface
- Connects to Front Panel Card via I2C
H2 - ISP Download
- Connects to PSoC programmer
H3- Serial Port or SPI (SD Card)
H4 - I/O
J1 - USB B
- 5V card Power
- USB to Serial comm port
J2, J3 - I/O Ports
- J3 connects to JOYPAD on GPA connector
J4 - Audio Out
- DAC is the Analog function generator in the PSoC
J5 - Z80 Signals
- Useful for monitoring the CPU lines
Software
- Hardware/Software options are set in the PSoC "Hardware_Config.h" file
- Comment out all but one choice
- Options

- GRANT_FPGA_CPM
- MULTIBOOT_CPM
Front Panel
- Card boots into Front Panel Control
- SRAM can be examined/changed in SRAM from the Front Panel
- Options to run Z80 or PSoC Monitor
- Upper right (SW32) = Increment address, read
- SW31 = Store data, increment address, read data
- SW30 = Load Address, read memory
- SW29 = TBD
- SW28 = TBD
- SW27 = TBD
- SW26 = Run Monitor
- SW25 = Run Z80
Z80_PSoC Monitor
- Press SW26 button (one in from upper left) button on Front Panel For 8 Bit Computers to run the Monitor
- PSoC Code Github repo
- Type to check the SD card
R4000
- Result:
Multiboot Multicomp (MULTIBOOT_CPM)
- CP/M Multiboot - Runs MultiComp 512KB SRAM version
- Insert "M/CPM 512KB" SD card
- Insert USB B cable
- Run PuTTY
- 115,200 baud
- Card will power up and cycle through all the LEDs on the Front Panel
- Press SW25 (upper left button) on Front Panel For 8 Bit Computers to run Multiboot software
- PuTTY will display
Press [SPACE] to activate console
- Press SPACE
- Press H for help menu

Available Commands:
:ccxxxxiibbbbbb Load Intel-Hex file record
Rxxxx Run from address xxxx
Sddd System boot
Iddd Init: Format directory
Pddd[,xxxx] PutSys: write system image[,loadaddress]
(No address: re-use last loadaddress)
Gddd[,xxxx] GetSys: load system track
Dxxxx[,yyyy] Dump memory from xxxx [,to yyyy]
D (no address) shows next block
Cxxxx Change/show memory at xxxx
CR advances "," quits
ddd is a decimal volume number,
xxxx, yyyy is a hexadecimal address.
Leading zeros may be omitted.
ESC or ^C aborts.
