Thank you. Re: CFFA3000, I had never heard of that, looking at ReActiveMicro it sounds real nice. I'm still using a SCSI HD and Zip disk in my IIgs and another with an Alltech Electronics/Parsons Engineering card. Then there's my //e I just replaced a failed CMS HD with an Apple HD pulled from some Mac or other from eBay, oh and the //c. That they all work brings a real smile to me. I'll try mounting that ProDOS v4.2.3 .po file with KEGS or Bernie ][ the Rescue and see if I can move it to the //e. ProDOS v 2.0.3 doesn't know 2/29/2024; thinks it's Wednesday. I know there has been talk of date tables or some such in ProDOS but I don't remember what or where. Nothing really earth-shattering , just something else to think of. -- Mark Wade
