1MB Chip with 1.5MB expansion

Misko78 · 09 December 2021, 10:43

Is it possible to have 1MB chip ram + 1.5MB slow ram?
It's a Rev.6 board and expansion is Zydec Superboard with Gary adaptor.

Ah, found all the answers in earlier forum posts. It's not possible.

Back in the days I had a similar board and with a Gary adapter and an Agnus adapter it was possible to have both 1M chip and 1.5M ram. However that didn't work well with any other expansions so I never really used it - 1.5 of the 2M on that expansion card became donor chips to my A590. Can't remember the name of the board though.

It is dr. Jones! Have you looked here? I have one in my rev.5 A500 to give me 1MB chip and 1.5MB (slow) fast ram.
