After two years of tapping with my fingers I decided to treat my old Gen 1 7" resistive Scroll to a Keyboard Case.
I ordered from this e-bay seller tomtop_shop. Yes, delivered for under £7 and arrived in four days
Copy paste into ebay search: Mini USB Keyboard Leather Case Protective for 7 inch 7" Tablet PC Black UK
(look for UK Shipping)
The old 7" resistive Scroll has a USB mini Host so the theory is this keyboard should work. I can report it works a treat. Even the function option works allowing escape to Home screen or Sleep mode etc.. Does not seem to impact on battery life either Oh, its not leather its 'faux' leather. The top clamp is spring loaded, pull it upwards to fit the top of the tablet. I did have some sticky rubber strips so have stuck to the inside of each clamp to stop it sliding ok now though
NB: I am not sure of the functionality of the newer Scroll tabs mini USB ports i.e.. USB Host- allows the connection of a mouse or keyboard etc... So please only go for this if you are sure the USB mini will support 'host'/ OTG 'on the go' on your newer Scroll Options tablet.
