 |
|
I may have mentioned it in previous threads but since it's a very useful function present in many copiers, most notably Super Magicom/Supercom, Pro Fighter and pro fighter clones, I'll make a dedicated post about it.
If you have a cartridge inserted in the copier, press reset and keep the B button pressed, it will copy it to the DRAM and run from it.
Even though some copiers have built-in ram test functions, these can sometime fail to detect a bad connection or an issue with a ram board.
Using this function is much faster than loading from a floppy drive.
Some revisions of the Supercom Partner (a PF clone with a banking system) will dump to content to the DRAM and the SRAM, then verify both.
