1Soldering ceramic capacitors
The capacitor C7 (CPU) must be placed on the solderside of he PCB and soldered on the component side, before placing the IC socket.
2Led polarity: Power, Disk, Reset and Halt.
The square pad on the PCB indicates the Cathode side of the LED. Long leg of LED is the Anode.
After inserting the ROM with the Scrumpel monitor you can power-up the board. But you need to connect COM1 via FTDI or better a TTL-to-RS232 converter to a PC running a terminal program with hardware handshaking on. Otherwise the board will not run the monitor, because it's waiting for sending serial info on COM1. The default speed is set to 38400, data is 8N1 ( 8 bits, no parity, 1 stopbit). The Dead-on DS3234 RTC-module is required for saving and setting the baudrate to another speed.
If you have connected the 20*4 LCD some info is shown with the current time and date if the RTC is also inserted. On the terminal the monitor greets you with displaying monitor greetings and, if RTC is installed the current temperature, time and date.
ATTENTION! You must install the LC- display to be able running the monitor. The software uses hardware LCD-status check, if no LCD is installed the monitor is waiting for LCD to become ready.
4Copying a diskimage to a sd-card
Download the file zcpm.tgz, uncompress it. Copy this image to a sd-card with less or equal then 2GB capacity. In Linux this is done by the dd command: sudo dd if=zcpm.img of=/dev/sdX
Where sdX is the device which is assigned to the sd-card. I.e sdc. Caution! Be careful! Be sure it is not your boot-disk, otherwise you make your computer unbootable! For windows users: use a sd-card image copy utility.
