Z180 Mark IV
The Z180 Mark IV is a single board computer, meaning it may run stand-alone. It also has an interface to the RetroBrew bus (ECB) for access to additional peripheral boards.
- A Z180 cpu up to 33Mhz. Using an 18.432Mhz oscillator, the newest Z180 processors are easily overclocked 2X to 36.864Mhz.
- 512k of static RAM memory. Up to 1Mb of EPROM, or up to 512k FLASH memory.
- Date/time clock with battery backed NVRAM (DS1302). Backup power is usually provided by a 0.22F super-capacitor.
- Terminal connection through an RS-232 port using an IBM-PC serial port 10-pin header.
- Twisted pair FDX communication through an RJ-12 (6P4C) modular jack.
- A Secure Digital (SD) card slot. Standard, HC, and XC cards are supported by ROM firmware.
- A 40-pin IDE connector which supports 8-bit transfers, and is usually used with a Compact Flash card Master/Slave adapter.
Power is supplied to the Mark IV SBC through the ECB bus, or through a 4-pin Molex connector (PC/AT disk drive power connection). The board operates using +5V power only.
