tools/upload: use A! instead of C! to write
By default, it changes nothing, but it allows interesting setups, such as using AT28! for directly uploading to EEPROM. I've also updated the EEPROM recipe to upload directly to 0x2000. I'm not sure what has changed, but it's working fine now.

## Writing contents to the AT28

|

The driver provides `AT28!` which can be plugged in adev's `A!*`.
|

The driver provides `AT28!` which can be plugged in adev's `A!*`. You can do so
|
||||
with `' AT28! A!* !`.
|
||||
|
||||
First, upload your binary to some place in memory, for example `a000`. To do so,
|
||||
run this from your modern computer:
|
||||
Then, upload your binary to EEPROM with:
|
||||
|
||||
./upload <tty device> a000 <filename>
|
||||
|
||||
Then, activate `AT28!` with `' AT28! A!* !` and then run
|
||||
`0xa000 0x2000 <size-of-bin> AMOVE`. `AT28!` checks every byte for integrity,
|
||||
so it there's no error, you should be fine. Your content is now on the EEPROM!
|
||||
|
||||
Why not upload content directly to `0x2000` after having activated `AT28!`?
|
||||
Technically, you could. It was my first idea too. However, at the time of this
|
||||
writing, I always get weird mismatch errors about halfway through. Maybe that
|
||||
the ACIA interrupt does something wrong...
