@hkz There's no real changelog that I know of. I took the firmware source for the Apple IIc and modified it enough so that it can also build for the Liron card, and all the different SoftSP variants, so you can use that to see what is actually changed. https://github.com/btb/ProtocolConverter

@hkz It's definitely confusing. SoftSP is the work of Wing Yeung, from MFA2 labs and KbooHK, a modification of Apple's original SmartPort code, which bit-bangs the DiskII hardware in the absence of an IWM chip. v6a is the latest version, released in conjunction with the Grappler Minus, but as far as I know it applies to all hardware.

@hkz simplest of all would be making it use the non-diy softSP firmware variant, then there’s no need for bank-switching, etc. but in the end i think it would only save 1 chip, and I hadn’t done it because I didn’t want to undercut mfa2 labs too directly.

@hkz there’s not really that much to simplify anyway, my page explains what can be easily left out.

@hkz The SoftSP-DIY firmware works on my grappler+ clone https://github.com/btb/GraphicPlus
There are also simplified versions of it out there but afaik those just have gerbers available
