Creating new CF disk for ZRC

This page describe the process of creating a new CF disk from scratch for ZRC. There are multiple approaches and I have not decided on the final one. I'm documenting the current process. We start the process with a ZRC with a new CF disk.

After power is applied, there is a 3-second window when a serial bootstrap file can be sent to ZRC to be executed. ZRserld.bin is the file that should be send as a binary file. Once ZRserld.bin is received, it will run and display: ZRC Loader v0.0 Auto start at 0xB400

once loaded, ZRCMon will run automatically: ………………………………………………………………………………………………………………………………………………………….UX

Initialize disk C with “clrdir c:”, type 'Y' to execute the command

Switch to drive C and use xmodem to create the file 'ROMWBW.IMG':

“b:xm r romwbw.img” and pick 'RCZ80_zrc.rom' as the file to upload.

Once xmodem completed the loading of ROMWBW.IMG, the installation process is completed.

The CF creation process can be automated with TeraTerm macro. Unzip and place the file in c:\TeraTerm\ZRC. The serial port is set to 115200 N-8-1 with RTS/CTS hardware handshake. Press reset and run the macro 'newZRCCF.ttl' within 3 seconds of releasing the reset button. It will take about 5 minutes to install.
