Supporting larger than 1 gig volumes and FFSv2 would make worrying about space less of an issue, and/or supporting having a small partition used for transferring files and booting the kernel in a simpler, better documented way would be good, too.
I’ll put these on my ever-lengthening queue of things to work on. I have a fair amount of low-level Classic Mac OS development experience, plus a legitimate copy of the Jasik Debugger, so I’m up to the task as long as I have enough round tuits.
I’m also working on the details for a SCSI<->iSCSI bridge for vintage machines, which should help with both the speed of filesystems as well as the fact that real SCSI drives are starting to bite the dust. Even at 100Mbps (12.5 MBps) it’ll be faster than 5 or 10 MHz narrow SCSI and should support local SD cards as well.
I’d like to also add support for EN/SC emulation for devices like the PB1xx series that don’t have a good way to do it otherwise, but I don’t know if we have driver support for that. Nor have I found any kind of documentation on the command set they used, plus my old Asante EN/SC seems to have evaporated into the ether, so if anyone has some leads on getting a real one, I’d be grateful.
