Hi
Does anyone have a schematic of a memory mapper that can use 1 MB SIMMs ?
2nd question: where do I get 50 pin header connectors or experimental MSX
slot PCB's ?
3rd question: anybody happens to have the schematics of a Canon V20 MSX1 ?
4th question: does anyone know of a MSX-site tha

Depends on where you buy it.
The cheapest I have seen is the Padial´s one. It´s wthout the box,
only the card. It cost approx 80USD.

Too much. Programmes don't arrive even to 512 K.
If you refer to the price, something like 85 US$ or so...

The POKE -1,shit is different for every machine. Try with this universal
