Current status: Zilog Peripherals board is supported by configuration. Baud rate selection is supported. Parity, Data and Stop bit changes are not currently supported. Driver changes are available as part of the 2.9.1+ build of ROMWBW. https://github.com/wwarthen/RomWBW ===== Proof of Life ===== SBC V2 Settings K12 Pin 1-3 ZILOG PERIPHERALS SIO/0 Port B0h 4.9152MHz X5 Pin 15-16 (Use Crystal) X5 Pin 9-11 (/16) X6 Pin 3-5 (TXCA=PHIX) X6 Pin 8-10 (RXTXCB=PHIX) X6 Pin 7- X4 Pin 12 (RXCA=PHIX) <code code> RetroBrew HBIOS v2.9.0, 2018-07-17 SBC Z80 @ 8.000MHz 0 MEM W/S, 1 I/O W/S, INT MODE 2 512KB ROM, 512KB RAM UART0: IO=0x68 16550A MODE=38400,8,N,1 SIO0: IO=0xB6 SIO MODE=38400,8,N,1 SIO1: IO=0xB7 SIO MODE=38400,8,N,1 DSRTC: MODE=STD Sat 2000-01-01 01:05:16 MD: UNITS=2 ROMDISK=384KB RAMDISK=384KB FD: IO=0x36 UNITS=2 PPIDE: IO=0x20 NOT PRESENT Unit Device Type Capacity/Mode ---------- ---------- ---------------- -------------------- Disk 0 MD1: RAM Disk 384KB,LBA Disk 1 MD0: ROM Disk 384KB,LBA Disk 2 FD0: Floppy Disk 3.5",DS/HD,CHS Disk 3 FD1: Floppy Disk 3.5",DS/HD,CHS Serial 0 UART0: RS-232 38400,8,N,1 Serial 1 SIO0: RS-232 38400,8,N,1 Serial 2 SIO1: RS-232 38400,8,N,1 SBC Z80 Boot Loader Boot: (C)PM, (Z)System, (M)onitor, (L)ist disks, or Disk Unit # ===> BOOT CPM FROM ROM CBIOS v2.9.0 [WBW] Configuring Drives...
