Improve debug performance, abstract debugger. (#61)
Stop stringifying opcodes during runtime and only do so upon inspection. Moves all the debugging logic to a common place to allow building an interface.

Update Typescript and Jest dependencies (#55)
This is a mechanical update to Typescript and Jest dependencies, but
since I also upgraded `npm` to 7.5.2, the `package-lock.json` file has
a lot of churn.

Convert cards/disk2.js to Typescript (#54)
* 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.

See
https://www.growingwiththeweb.com/2020/10/typescript-readonly-typed-arrays.html
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.

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.

ProDOS image format tests and fixes (#51)
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.

DOS 3.3 image format tests and fixes (#49)
* 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.

More typescript conversion (#46)
* 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.

Apparently, I broke everything when I removed the underscores from the

Typescript conversion of several files, including js/cpu6502 (#38)
* Convert `js/util.js` to Typescript and add tests

Besides converting `js/util.js` to Typescript, this change also adds
`js/types.ts` that defines common types used in apple2js. Some of
these types, like `byte` and `word` are for information only.

* Convert `js/base64.js` to Typescript

This also adds a new type, `memory`, that is either an array of
numbers, or a Uint8Array.

* Convert `js/ram.js` to Typescript

This change does not convert `RAM` to a class; it just introduces types.

* Basic typing of cpu6502

This is a really rough first pass. There are some problems that can't
be fixed until this is turned into a real class, but at least all of
the function arguments are now typed. This caught a few cases where
extra arguments were being passed in.

* Convert `js/cpu6502` to a class

In theory, idiomatic classes should be better than the previous
closure-based classes. However, this conversion shows that the
instruction table does not fit well with idiomatic classes as method
referenced in the table need to be called with the correct `this`
everywhere.

This should, at best, be considered a first attempt.

Add configuration and dependencies to support Typescript (#37)
This change adds basic, non-optimal support for Typescript with
webpack. It functions well in development mode and deployment boots
ProDOS. There are probably many ways this configuration can be sped
up, but I haven't investigated that yet.

Note that no Typescript files are added in this change; it is merely a
configuration change.

Track raw parallel port output and allow it to be downloaded (#36)
This change adds a download link to the printer dialog. The contents
of the download will be the raw bytes written to the parallel
interface. Note that often these bytes will have the high-bit set
causing the contents to look like gibberish.

However, this is extremely handy because it allows one to turn the
printer output into a PDF:

1.  In Appleworks (for example) configure an Apple ImageWriter in slot
    1 and print a file.
2.  Download the printer output.
3.  Download the header file from https://github.com/AppleWin/AppleWin/files/1168047/ImageWriterEmulator-NoLF.ps.txt
4.  In Linux, run:
    ```shell
    $ cat ImageWriterEmulator-NoLF.ps.txt raw_printer_output.bin | ps2pdf - printer_output.pdf
    ```

Note that the parallel port emulation in apple2js does not yet support
Print Shop, so I haven't been able to test that out.

Fix bug where the alert dialog would not close (#32)
Micromodal maintains a reference to the current open dialog in
this.modal. If one dialog is open while opening another, Micromodal
can get confused and maintain a reference to the wrong one.

One of the problems is that the close action is not instantaneous, so
even closing one dialog and opening another immediately after can
cause the problem.

This change adds a small delay before opening the alert dialog to work
around the problem.

Fix a problem where sometimes the emulator would run too fast (#34)
Before, when using `requestAnimationFrame`, the emulator did not save
the id returned by the browser. This broke the invariant of `run`,
namely that on exit either `runAnimationFrame` or `runTimer` would be
set. This meant that sometimes when the emulator restarted, there
would be two callbacks to `requetsAnimationFrame` run on every frame.

Now the id is saved correctly and the invariant of `run` is maintained.
