A500+ with 1,5 MB Chip Memory

mombasajoe · 07 May 2008, 08:28

For testing WHDLoad installs before transferring them to my A500+ I would like to emulate my machine with WinUAE:

A500+, AlfaPower with 8 MB fast mem and CF card (which I also use as HD in WinUAE) and 1,5 MB chip mem (1 mb on mainboard + 512kb inside the trapdoor).

No problem:

including CF Card as HD, 8MB fast mem, chipset, CPU etc.

Problem:

I am only able to configure 1 MB or 2 MB chip mem in WinUAE. Is there ANY possibility to emulate 1,5 MB chip ram?

Thanks for your help.

I hadn't realised what rare beasts the A501+ 1Mbyte CHIP RAM trapdoor cards are.

An A500+ can obviously have 2Mbyte Chip Memory with the right trapdoor RAM expansion. I started to look for a cheap one a couple of months ago for a mate and still have only seen two for sale on Ebay:

In the same time period 10's of 512Kbyte RAM expansions have sold and just two 1 Mbyte ones!

I would´nt call something "rare" that can still be regularly ordered (not ebay but "real" shop : vesalia.de).

I just haven´nt bought one yet because I am too stingy for paying 20 EUR (+shipping) for something I don´t really need.
