This is the Floppy Disk Controller PCB for my replica Acorn Atom Computer.
It fits into an Electron case in place of the original PSU.
As well as being able to hook up to 'real' 3.5" or 5.25" floppy drives it also includes a built-in (optional) GOTEK (note the GOTEK requires a surface mount CPU to be fitted to the board).
I am now able to supply the board with the surface mount processor fitted and programmed, see this listing https://www.ebay.co.uk/itm/405065617734.
Please note this board will not work with a real Atom as it doesn't carrying the additional memory required.
Further details can be found on my website, including the Schematics and BOMs (Bill Of Materials).though you'll have to search for it because I can't put a link here - try 'replica acorn atom'.
I will combine postage on multiple items, please ask for a total before paying as I cannot combine postage after you have paid !
