The
ACRTC Board |

Here
you will find example programs designed to help with
programming the ACRTC Graphics Controller on Mega-68000
and Mega-68030 Computer Systems using BASIC and 'C'. |

Tiny BASIC |
|
Standard Tiny BASIC does
not offer much in terms of functions and general
mathematical capabilities. The version of Tiny BASIC
here though (Tiny BASIC for ACRTC) is a heavily modified
version of Tiny BASIC containing lots of additional
functions that make programming the ACRTC on a Mega-680x0
Computer System fun and easy to do with next to no
technical knowledge needed. |

From now on
when we refer to Tiny BASIC we really mean Tiny BASIC for ACRTC
or TBA for short. |

Tiny BASIC with
CP/M-68K |
|
Tiny BASIC can be
installed as a transient utility program and invoked
from a CP/M-68K command prompt as and when required -
how cool is that? |
|
|
|
The easiest way to install
it is to use: |
|
C-Kermit on the PC |
|
G-Kermit on the
Mega-680x0 Computer System |
|
|
|
Setup instructions
for C-Kermit for Windows can be found here: |
|
Software/C-Kermit |
|
|
|
The procedure
below will install Tiny BASIC |
|
|
|
Note: |
|
If the
following is not true |
|
B: - CP/M-68K
drive containing the G-Kermit utility |
|
D: - CP/M-68K
drive to install to |
|
apply drive letter
substitution to the procedure as necessary |
|
|
|

Download the following file: |
|
|
TBASIC.68K |
|
2. |
Copy the
file to the C-Kermit transfer folder on the PC |
|
3. |

|
5. |
At the
A> prompt type: D: |
|
6. |
At the D>
prompt type: B:GKERMIT -G TBASIC.68K |
|
|
The
Mega-680x0 receives and processes the binary file, |
|
|
when
reception is complete, the Mega-680x0 will
accept the
next command |
|
|
|
|
To launch Tiny
BASIC from the CP/M-68K command prompt |
|
Type: TBASIC |
|
|
|
Tiny BASIC without

Mega-680x0 Computer System |
|
5. |
At the
SYS> prompt type: LO |
|
6. |
Paste the
copied text into the Console Window |
|
|
The
Mega-680x0 receives and processes the S-Record
formatted binary file, |
|
|
when
reception is complete, the Mega-680x0 will
accept the
next command |
|
|
|
|
To launch Tiny
BASIC from the SYS> prompt |
|

The System ROM
contains Enhanced BASIC |
|
|
|
To launch Enhanced
BASIC from the SYS> prompt |
|
Type: BA |
|
|
|
C |
|
The simple ACRTC 'C' programs/demos
presented here were compiled and
linked on the Mega-680x0 target hardware using
the inbuilt CP/M-68K compiler and linker. Step
by step instructions on how to generate the
executable files from the provided 'C' source
files are included. |
