No magic, there are probably small signal inverters in the socket below the EPROMs. The basic schematic for using EPROMs is documented many times in this forum.
Enter

Code: Select all

SBYTES flp1_lightning_bin,49152,16384

to get the lightning binary.

Probably _lngINIT command to activate it. As Marcel says, discussed often before e.g. viewtopic.php?t=224

Link to a manual in that thread too.

Makes me wonder, why it appears twice on the screen, I often have seen this by others.

Old TK2 ROMs had special code that detected if it was invoked from $CC000 and in that case checks if it was already initialised from $C000. So probably some incomplete address decoding going on.

The ICE rom does the same thing, showing up twice.

Hi,

I bought LightningSE on ROM when in the 1990s, it was a good addon, but used up the ROM port.

Minerva rom graphics improvement give 98% of speed of LightningSE, according to the Minerva Manual,but I never compared this in a test and I can not remember anyone doing a speed comparison.

There is a nice attach font option to specified channel command, a little redundant,since TK2 and SMSQ/E does it better.
