## Introduction
|
|
|
|
I recently built myself a Microdigital TK2000, a clone of an almost-clone (the MPF-II) of an Apple II.
|
|
|
|
Building it from the files found in [this github repository](https://github.com/clemarfolly/Microdigital-TK2000) proved to be a [bit of an adventure](https://github.com/hkzlab/TK2000_Build_Notes),
|
|
but I took a liking to the computer, so I started developing [boards](https://codeberg.org/hkzlab) for it.
|
|
|
|
Hardware fiddling is fine, but given that there isn't much software available for the machine and that I wanted to experiment with the [Calypsi toolchain](https://www.calypsi.cc/) a bit, I decided to
|
|
pick a simple game concept and develop it for the machine.
|
|
|
|
I decided for 2048, the now-classic tile sliding game, as it provided several advantages as a first time/playground project:
|
|
|
|
- Doesn't need complex graphics hardware or advanced artist skills
|
|
- It can be drawn in B/W with static graphics, but animations and colors can be added in the future
|
|
- Sound is not needed either, but can be added for simple events like a tile slide or a button press
|
|
- The game logic is pretty simple
|
|
- Not CPU or memory intensive
|
|
- Can be expanded with support for additional hardware (sound cards, video cards, timers) if so desired, but it's not necessary
|
|
- Floppy drive can be potentially used not only to load the game, but also for saving the high score
|
|
|
|
|
|
|
|
### Current state
|
|
|
|
The game is playable, and the following features have been implemented:
|
|
|
|
- B/W mode
|
|
- Single graphical tileset
|
|
- Crude sound (only beeps)
|
|
- Control via keyboard
|
|
- 5x5 grid, with randomized start and new tiles
|
|
|
|
## How to play
|
|
|
|
You can move the tiles using the cursor keys. Pushing CTRL-R will make you lose the game and restart it.
|
|
|
|
The game ends once you reach a tile with a value of 2048.
|
|
|
|
### Floppy version
|
|
|
|
Just put your floppy in the first drive and power on the TK2000. It will autoboot.
|
|
|
|
### Tape version
|
|
|
|
Power on the TK2000 with the sound player connected to the EAR input. Once at the `>` prompt, type the following
|
|
|
|
```
|
|
CALL -159
|
|
```
|
|
|
|
This will drop you into the monitor, `@` prompt. Type
|
|
|
|
```
|
|
801.4EBBRA
|
|
```
|
|
|
|
And press play on tape. If the load completes successfully, the computer will beep and give you back the prompt. Now type:
|
|
|
|
```
|
|
801G
|
|
```
|
|
|
|
This will start the game.
|
|
|
|
## How to build
|
|
|
|
You need the following:
|
|
|
|
- GNU Make (I used the one provide via [MSYS2](https://www.msys2.org/))
|
|
- [Calypsi 6502 toolchain](https://www.calypsi.cc/) (tested with 5.10)
|
|
- [AppleCommander](https://github.com/AppleCommander/AppleCommander), "ac" command line version (tested with 1.9.0)
|
|
- [dsk2woz](https://github.com/TomHarte/dsk2woz)
|
|
- vitasam's fork of [c2t](https://github.com/vitasam/c2t)
|
|
|
|
## The future
|
|
|
|
I plan to refactor the whole game, modularize it, and leverage loading of single modules from a floppy disk. This
|
|
should give more flexibility, expandability, free some memory and allow me to exercise the floppy drive routines I wrote.
|
|
|
|
As such, V1.0 will probably be the last one supporting loading from tape. |
