Apple IIe enhancement kit questions

Hi there,
I located the US enhancement kit for my Apple IIe PAL and it seems the video ROM is a lot smaller than the PAL version. It does not fit my socket???

The US video rom is listed as: 342-0265-A on the http://www.reactivemicro.com website but in the Official Apple IIe document its referred to the character ROM and the PAL german video ROM is listed as: 342-0275.

http://www.apple-iigs.info/doc/fichiers/Apple%20IIe%20Enhancement%20Kit%20Dealers%20Installation%20Instructions.pdf

Is the 342-0275 rom bigger than the 342-0265? If so I'm in need of a 342-0275 rom if anyone has one Smile

So close but yet so far. hahaha

Hi SpeedyG,
Unfortunately no. Are the 342-0275 roms available? Its strange why its a bigger rom than the US version.

Here is my motherboard. Ive changed the CPU where its written 6502A, The CD ROM, the EF ROM and the one I'm missing or does not fit is the VIDEO rom. In the second photo you can see my original Video rom with the "US Video Rom" Its two pins bigger than the US one.

hello robo007,
if you want to
get by yourself further in understanding the topic, i recommend you to read the book from Jim Sather - Understanding the Apple IIe.pdf and downloading it from:

http://mirrors.apple2.org.za/Apple%20II%20Documentation%20Project/Book /Jim%20Sather%20-%20Understanding%20the%20Apple%20IIe.pdf

there in the book your eyemark should concentrate to the following chapters and parts of the chapters:

10-10
and
G-2
amd
I-2
it anyhow should be a good idea to download the book and read it sometime entirely to better unterstand the IIe in depth..... and using that time will be well invested for the future of your Apple.....
