First attempt at making fire starter from collected sawdust, paraffin wax, and an empty egg carton.

The molten wax seemed to leak from the bottom of the carton. So the whole operation was time consuming, messy, and I’m lucky I didn’t set the backyard shed or myself on fire. Obviously I’m an amateur at everything I do. But it was lots of fun. 🔥 😅

Empty egg carton has been filled with sawdust and molten paraffin wax to make fire starter for camping.

I'm debugging the ROM emulation on the Firestarter. It looks as if the code to monitor ROM enable and ROM selection is working but the host crashes once it starts accessing the ROM.

The first access of the ROM is when BASIC calls KL_INIT_BACK to initialise background ROMs.

The first read is the LD A,(&C000). A few cycles later the ROM's init routine at &C006 will be called.

A nice end to Sunday morning with a quick Delphi utility to convert a ROM binary to C source code.

Time to try some ROM emulation. The first step is to sniff the ROM enable/disable states and the currently selected upper ROM.

The code for this is, again, simple. It tests the I/O address for the ROM select IO port, and also the gate array IO port. If it's the gate array it tests the register select bits of the data and extracts the two ROM disable bits.

$Source code: //IO *into* Firestarter void io_in_irq_handler() { //Get the IO address read by the address PIO uint addr = PIO_IO->rxf[SM_IOINADDR]; //and the data from the data in PIO uint data = PIO_DATA->rxf[SM_INDATA]; //Mask to get the I/O address bits for device select uint maskedaddr = addr & IOMASK; //Decode IO address here. If it's for us then... if (maskedaddr == ROM_IOADDR) { //... process it rom_select = data; // printf("%.2x %c ", data, data); // lastioindata = data; // in_count++; } else if (maskedaddr == GA_IOADDR) { //Gate array register uint ga_register = data & 0xc0; if (ga_register == 0x80) { //RMR register, grab the ROM select bits upper_rom_disable = (data >> 3) & 1; lower_rom_disable = (data >> 2) & 1; } } //(The interrupt is automatically cleared when we read the FIFO) }$
