I’ve added an /int button, and there are a few other minor improvements. If the Z80 wants to write a byte on the data bus it sets /WR low, if it wants to read off the data bus, /RD is set low. It adds Z80 CTC which is used for generating periodic interrupts and as a vectored interrupt controller for UART and PPI. Build a PIC controlled DDS VFO, 0 to 6 MHz. Single board computers are used for a variety of things. The system also includes a memory management unit, serial ports, and keyboard interface. pdf), Text File (. A0 to A10 go into the ram chip from the Z80 and that is 2k. This is the latest variant from Just-4-Fun, after the Z80-MBC2 and V20-MBC. To be able to do this, I used some of the basic schematic elements and features available on the SBC V2 board and used some glue logic to match the signals for the ECB backplane.

The Vector ZCB and FlashWriter II video card are implemented. described it, the Z180 originated with Hitachi as Z80 not freerunning. It is the “evolution” of the Z80-MBC, with a SD as “disk emulator” and with a 128KB banked RAM for CP/M 3 (but it can run CP/M 2. you can easily find Basic, C, Assembler, Pascal, Fortran, Cobol compilers, and some of these are already provided in the virtual disks on the SD). These are all the minimal requirements to have a fully functional computer. The SoftCard mode does take over the Apple II and halts the operation of the 6502 and this card has direct access to the Apple II's bus and hardware pluged into it. e. The N8VEM Single Board Computer is a home brew Z80 small computer project. Compared to the first version this version features updated MMU with four banks, each one of those banks can be mapped to any 16 KiB page in 1 MiB on-board memory. Read-only memory, as the name implies, is only readable and not writable which creates a problem for us. by Thomas Scherrer and Kenny Andersen. It follows the same "concept" of the previous Z80-MBC2 and V20-MBC boards, using a PIC18F47Q10 MCU as EEPROM and… It's a Z80 SBC (single board computer) that can run CP/M and can be built very cheaply - the PCBs are $20 plus shipping.
