* 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
field names and added them to the method names. The fix is just to
rename the methods `getCycles` and `getSync` and call it a day.
* 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.
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.
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.
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.

Modern browsers set the 'location' property on keyboard events when
the key is located in several places. The ALT key, for example, can be
either on the left or the right side of the keyboard.
This change uses the location to determine which Apple key to
activate, if it is available, and defaults to the old behavior if not.
Normally, F2 causes the browser to go full-screen, showing only the
Apple screen. However, in Chrome, the user can exit full-screen mode
by pressing ESC. Since ESC is used frequently on the Apple //e, this
limits the utility of full-screen mode.
To work around this problem, this change adds Shift-F2, which will
make the Apple fill the window without going full-screen. This allows
the user to go make the window full-screen in some other way, thus
enabling the use of the ESC key.
Note that the method used is almost entirely implemented in CSS, with
just a few lines of code to change the classes on some elements. This
may not be the best long-term way of implementing this feature.
