Ian Flanigan	9d4a265daf	Refactor storage types ... Today, lots of information about how a file or JSON becomes a disk image is embedded in the metadata for the image and/or disk. This makes it hard to write back to the source when the in-memory disk image changes. This refactoring is an attempt to break out all of the bits of logic into composable pieces. While this is mestly concerned with reading right now, the idea is that it will eventually allow configuring writing as well. The main goal is to allow round-tripping to the same file on disk, but, in theory, it could also save to a different file or the local database, too. Note that this is a work in progress.	2022-06-05 23:30:34 +02:00

Ian Flanigan	dc13b6a59a	DOS 13-sector tests and fixes (#53) ... Like the DOS 3.3 and ProDOS sector order issues, this change fixes the physical order of the sectors on 13-sector disks when nibblized. This change also adds tests for the 13-sector format to verify the sector order. One of the crazy things is that _Beneath Apple DOS_ failed me in this instance because it doesn't discuss what happens to the last byte in "5 and 3" encoding anywhere (AFAICT). I went back to the DOS 3.1 source released by the Computer History Museum here: https://computerhistory.org/blog/apple-ii-dos-source-code/ The code is in `appdos31.lst` in the `POSTNIB` routine on line 4777.	2021-01-03 15:01:30 -08:00
