No 5.25" disk images.

Question

No 5.25" disk images.

Closed this issue 11 years ago · 4 comments

Producing 5.25" disk images would allow me to run PoP on my actual Apple ][e and a greater number of Apple ][ emulators.

I don't currently support the production of these images because the RW18 routines included in the github repository only exist for 3.5" media.

Having access to a nibble copy of the two sides of an actual retail 5.25" disk would give me access to the machine code for the RW18 routines and probably provide enough information about the actual disk encoding that I can verify the RW18 support that I would need to add to my crackle disk imaging tool.

I still need to get my hands on nibble images of the original 5.25" PoP disk.

I am currently investigating an interim solution that may allow me to hack 5.25" support into PoP so that I can run it on my Apple IIe hardware. It won't be the exact same code path used in the released 5.25 PoP disk but it will be progress in the correct direction.

I have made some progress on this issue. I committed notes that I have made on the RW18 format required for getting PoP to run off of 5.25" disks. 66a44bb

Now builds 5.25" disk images on OS X hosts with commit: dee4b43 I will update and test for Linux and Windows soon.
