For the floppy emulator - last year I bought this one through amazon:
https://www.amazon.co.uk/gp/product/B01 ... UTF8&psc=1Haven't used it recently, but I think it worked just fine.
Here's a link to a thread in here, where I describe the installation process - it's the same for the HDR as for the D8B:
viewtopic.php?f=2&t=1376As for the CF stuff:
I'd suggest getting one of those that can be seated in one of the expansion slots on the back - makes it easy to change the CF card - of course this is more important on the HDR, but it also makes it easy to backup, or reinstall the D8B, should the need arise.
Here's the one I bought a few of:

For the CF cards themselves:
For the D8B your biggest problem will be finding a small CF card. A 1Gb card will be more than enough. I ended up with a 4Gb one, becuase that was what I could find. Dont spend money on fast cards for the D8B. I think this was the one I got:

Someone else in here had good experiences with the Sandisk Extreme, which is also what I bought:

They work nicely, and changing cards is easy.
Hope it all helps.
