First, the Applicard is new to me. Second, making bootable CP/M disks is a distant memory. I'm trying to dust off brain cells that haven't been accessed in 30+ years.
I download the two CP/M disk images (PCPI ProDOS Disk 1.po and PCPI ProDOS Disk 2.po), copied them using CiderPress to my ReActiveMicro CF card on my Windows PC, booted the Apple IIe with the ReActiveMicro CF card, and used DiskMsker 8 (I'm not very familiar with Diskmaker 8) to create the two system disks. I removed the ReActiveMicro card, installed the Applicard in slot 4, and tried to boot from the first system disk, and I get "UNABLE TO LOAD PRODOS" error message. The disk1 image has the following files on it:
I'm sure I'm doing something wrong, but I have no idea what it could be. Any suggestions would be greatly appreciated!
