* Refactor disk handling to allow disk processing to happen in a worker
* Type cleanup
* Convert format handlers to TypeScript
* Convert CFFA to TypeScript
This is mostly a mechanical change; there are still lots of things
about `ui/apple2` that could be improved. The change also converts a
few dependencies of `ui/apple2`, like `applesoft/compiler`.
Besides the straight conversions, some other packages have changes to
make all of the typing work out.
Lastly, `@types/micromodal` has been added as a development
dependency.
* Convert `cards/disk2.js` to Typescript
This is mostly a straightforward conversion of `cards/disk2.js` to
Typescript, with the following exceptions:
* `setState()` did not restore the drive light state correctly
because the callback was called with the old `on` value.
* `setPhase()` did not work for WOZ images.
* `getBinary()` did not work for `nib` files.
* `getBase64()` did not work for `nib` files and maybe didn't work
right at all.
Even with these fixes, local storage still doesn't work correctly.
I have also added several TODOs where methods don't support WOZ disks.
* Convert most uses of `memory` to `Uint8Array`
There are many places in the existing code where we use `Uint8Array`
directly. This change merely makes the `memory` type equivalent to
`Uint8Array`.
This change also changes most ROM data to be read-only in Typescript
to ensure that it is not modified by mistake. This can't be done just
by applying `as const` to the declaration because `Uint8Array`s are
can not be expressed as literals. Instead, we create a new type,
`ReadonlyUint8Array` that drops the mutation methods and makes indexed
access read-only.

for details.
* Tighten types and document `disk2.ts`
While trying to understand the Disk ][ emulation, I tighted the types
and documented the parts that I could, including references to other
sources, like _Understanding the Apple //e_ by Jim Sather.
The one functional change is the addition of the P6 ROM of DOS 3.2 and
earlier. This is automatically selected if the card is initialized for
13 sector disks.
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.
Like the DOS 3.3 sector order issues in #49, this change fixes the
order of the physical sectors on the ProDOS disk when nibblized.
This change also adds tests similar to the DOS 3.3 tests to verify the
sector order.
Because the DOS 3.3 and ProDOS tests are so similar, the utility
methods have been refactored into their own file.
* Adds an initial test for DOS format (.do) files
* Fix physical sector order when nibblizing DOS 3.3 ordered images
Before, when `.dsk` or `.do` images were nibblized, the resulting
track had the sectors in the wrong physical layout.
Now the nibblized track has the correct physical layout (all sectors
in order) which results in the correct DOS 3.3 layout as well.
There is also a test that verifies the order.
* Add another test for a non-zero sector
The new test checks that the values in physical sector 1 are those for
DOS sector 7.
* Add test for all physical sectors on all tracks
This change also removes a few stray console.log calls in the test.
* Convert js/ram to a class
* Convert js/mmu to Typescript
* Convert js/apple2io to Typescript
* Convert js/canvas to Typescript
* Use new types in js/mmu
* Rename js/symbols.js to js/symbols.ts
* Remove the difference between readPages and writePages
As @whscullin said in PR #38, there's no need to have both readable
and writable pages since all implementations are currently both. This
change combines them into `Page`. Likewise, `PageHandler` now extends
`Page`.
`Apple2IO` now implements `PageHandler`. This caught a bug where `end`
had been renamed `endend` by mistake.
There are a few other formatting changes as well.
* Convert js/apple2 to Typescript
* Convert js/prefs to Typescript
* Convert all of the ROMs in js/roms to Typescript
Now all of the ROMs are classes that extend the ROM class. There is
some rudamentary checking to make sure that the length of the ROM
matches the declared start and end pages. (This caught what looks to
be an error in roms/apple2e, but it's hard for me to tell.)
The typing also caught an error where the character ROM was being
used for the main ROM for the apple2j version.
* Convert js/roms/cards/* to Typescript
* Convert js/formats/format_utils to Typescript
This change also seems to fix a bug with `.po` image files that
weren't being read correctly.
* Sort disks in category order
* Fix saving disk
* Fix keyboard not working after modal
* Make caps lock key on keyboard work, while keeping caps lock on virtual keyboard working too
* Fix delete local storage
* Fix minus key on Mac
* Remove backtick
