Hello all,
I have a German Apple IIe PAL and was wondering if the USA Enhanced upgrade kit would work in it?

ENHANCED IIe and the Video ROM is 342-0265, CD is 342-0304 and EF is 342-0303. Processor is 65SC02P-2

I see that the Video ROM is different to the Germany one. Will it still work? I'm not fussed about German language support as I run it in English mode.

Cheers,
Rob

Hello Robbo007,

it also works in the german PAL-version ....... i have an upgraded IIe by myself.... and i had no problems after the update.....

so just go ahead and upgrade..... the difference in the coding of the new VideoROm are only related to the so called mouse-signs ( a special Char set ) and some routines related to the double-hires-pages 2 and 3 ( the double hires pages 1 and 2 had been left unchanged... )..... and some additional code had been integrated related to the Interrupt and DMA-handling....

sincerely speedyG
