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.
* 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.
