Title: Standard PAL IC's for EMAXII Memory Expansion Board - needed - Post by: Mikke on April 01, 2021, 02:36:30 AM I decided to make a new Post here...
Hello EMAX II Guys, Maybe someone can help me here..... ? I managed to grab one of this old MemExpBoards ::!! It is a REV B Board ? It has the following PAL IC's mounted. IP430, IP437, IP436, IP440 So in my opinion it is a 6MB Expansion for a 1MB EMAXII vor full most possible 7MB My inquiries in some old PDF's etc. tell me the following about the PAL configurations on the MemExpBoard. For a 2 MB EMAXII you can do the following steps. 2MB -> 4 MB with 2MB DRAM MemExpBoard and "Standard" PAL's IP430, IP432, IP431, IP433 4MB->6MB with 2MB DRAM and "Standard" PAL's IP430, IP432, IP431, IP433 6MB->8MB with 2MB DRAM and "Standard" PAL's IP430, IP432, IP431, IP433 For a 1 MB EMAXII you can do the following steps. 1MB->3MB with 2MB DRAM MemExpBoard and the PAL's IP430, IP437, IP436, IP438 3MB->5MB with 2MB DRAM and the PAL's IP430, IP437, IP436, IP439 5MB->7MB with 2MB DRAM and the PAL's IP430, IP437, IP436, IP440 Can someone confirm this ?? Maybe someone can have a look at his 8MB EMAXII ?? Take a picture of the used PAL IC's ?? So if i want to get my 2MB Stereo EmaxII (Model 2213) run with 8MB i have to get the PAL IC's or PAL IC-Files from IP432, IP431, IP433.. ! A source for IP432, IP431 files i found in the net.. But has someone a IP433 Pal File or can burn a working PAL IC for me?? I will pay for it.. !! So please can anyone here help me ? Best regards Mikke |
