Yeah if you can keep the ram in the ZII area you will have no issues. 9.5mb of ram... I guess I have got too used to 128mb now

EDIT: didn’t mean that to sound negative. This board looks good

I guess this card is on its limit with 8MB Fast and 1.5MB Slow RAM because of the EC CPU Type, it can't address more than 16MB in total... 🤔
This is ok though since CDTV doesn't have any Zorro slot..

There is no "seller web page", these are available through Polish web site allegro time to time. I got hinted, registered there and bought one.

Ram is 8mb + 1,5mb slow fast area.

It comes with tool wich syncs card's rtc to CDTV's rtc, have kickstart to fast ram, disable fast ram options etc.
With that shape / size it fits perfectly inside of CDTV, without any tinkering.

Requires extended roms v 2.30 to work with CD-drive.

I'm going to use it with 7-bit clock port to SPI apdapter for a networking.
