the Tiny A440 was sold by OT computers, prior to Granville Technology purchasing the Brand name. However their systems did come with verious CDs on of them a driver CD included the manual on it as a .PDF
If you no longer have that please drop me an email and I will see what I can locate for you.
Please include your invoice postcode and/or Tiny (ot computers) account number and I will check your account to ensure I am looking for the correct one (O.T. did a couple of versions of the A440)
