Can you post a photo of the front and back of the gm 849a card, from what I can make out the difference is the addition of some straps for DMA access and would like to check for any other changes.

I'm still unable to get any files off the gotek unit, I have firmware version 2.14 and can scroll the files on the usb stick and can select the unit and see data being read and all other signal but the system either says bdos error or the system reboots after loading.

I've tried all versions of RPM and simon but the only luck I have is with the original rpm eprom and the .25 floppy disk.

time for the "Nicolet Z80 NICE".
