Hi,

Some month ago i bought a japanese memory mapper (ASCII MEM 768k) with afcourse an japenees manual.

It works fine, but i think that its working a bit different then other mappers.

It simply crashes with WB-ASM , when i select a page from that memory mapper and then use mon or dis to se the memory in that selected page the whole computer locks up.

i used testram.com to test the cardwridge and this program finds no errors!

Loadrom.com crashes to and mega16.com is working fine ...very strange...


On the box of the cardwridge there's a japanees text bla bla bla MSX-DOS2 bla bla bal, msx2,msx 2+ and TurboR ..

But it also works on my msx2 and 2+ without dos 2, and it works on my msx1 machinens without a problem (i use it on my msx1 for Sunrise IDE).

And afcouse i tried both cardwrige ports.

Ow normaly the page instruction in wbass = page <page>,<slot>,<subslot>,<mem>
but with this cardwridge page <page>,<slot>,<mem> is used , i asume this is because its in a cardwridge slot.

Does somebody now a bit more of this mapper ?

by the way, normaly in wb-asm u use page

Oeps forgot to say i that i have to use the page number with the wbasm instruction page with the mapper, maybe this is the problem ???

the PAGE instruction syntax for wbass2:

page <page>,<prim.slot>,<sec.slot>,<memmap>

for turbo R is't: page 2,3,0,7
puts mapper 7 in page 2, prim slot 3, sec slot 0 which will activate RAM on page 2

who remembers the philips and sony pages?

jups, and works perfect on the internal mappers of my philips 8250 (1 mb) and sanyo wavy70fd2 , but when i use the external mappers memory wb-asm simply crashes after trying to read those mem-locations.
