It's been some time since I've been this impressed with a retrofit....
I've just fitted an HxC Floppy Disk Drive Emulator (3.5" form factor SDcard version) to my old Emulator II and it's utterly brilliant!!
Installation is pretty simple. You need the 3.5" form factor SDcard version of the Rev.F HxC available here:
http://lotharek.pl/product.php?pid=42You also need a black 5.25 to 3.5" drive bay adaptor and a 34 way IDC socket suitable for a 3.5" drive.
And a suitable 3.5" floppy drive power Y-lead eg:
http://compare.ebay.co.uk/like/290736168104?var=lv<yp=AllFixedPriceItemTypes&var=sbar&adtype=plaBasically you remove the top 5.25" drive. Fit the 34 way IDC plug to the existing ribbon cable. Fit the HxC in the drive bay adaptor and screw it in place of the original floppy drive. Make sure the HxC is set to ID0A & B and set the jumper on the remaining 5.25" drive to drive 2. Plug the power into the Y-lead to both drives.
Format an SDcard in FAT32 on your PC, run the HxCFloppyEmulator program to generate a config file and download the EOS file image for a blank disk with OS from the EMXP website - emuiios31.hfe and copy it to the SDcard.
You can insert the card into the HxC and the EII will boot up off of it. You can configure the drive to boot from the floppy image of your choice.
The really cool aspect of this retrofit is that it supports both read and write which means you can load up your favourite floppies on the remaining floppy drive and copy them over to disk images on the HxC.
I've spent this afternoon doing just this and now I can take the SDcard out, place it in my PC, and simply copy all of the virtual disks over to back them up - Brilliant!!
The more of us who fit this upgrade and the more of us can exchange and share samples via the internet!
