Hallo Pasi, > Not quite, because for a cartridge you need to generate A13 ... A13 is on pin S AFAIK. Combining RAM1..3 and BLK1 with a single 4-input AND-gate (74LS21) will give you A14. Combining this A14 with BLK2 and BLK3 will give you the needed CS/OE signal. As you can see, in theory my solution can be used for cartridges as well. The GIF-file of this SCH is less then 16KB. I thought about attaching it to this mail but I am not sure if this is appreciated by the people not interested at all in this subject. For this moment just send me a private mail and I'll email it to you. I hope to be able to place on my site soon. Unfortunally the bookkeeping of my wifes bussiness has priority for the moment.
