Netronic TinyBasic for the ELF II

This repository contains a version of the Netronic TinyBasic interpreter, with the Basic IL (Intermediate Language) in a readable and assemblable format.

Tinybasic_IL.asm

When assembled comes close to the original.

Tinybasic_IL_Fixed.asm

There have been changes to the Interrupt Service Routine (ISR) for the 1861.

The original version used the R0 (Register 0 - DMA Pointer) to increment the time counter. This could potentially lead to memory corruption issues.

How to assemble

You will need to use ASL assembler: wel97459/ASL

asl -cpu 1802 -x -P -L Tinybasic_IL.asm && p2bin Tinybasic_IL.p Tinybasic_IL.bin

To test

Use EMMA 02

• Elf Tab
• Quest Super Elf
• Load the config for Netronic TinyBasic
• (File->Configuration->Load->Netronic TinyBasic->*)
• Then for RAM 2 load the the bin file.
