Rotronics Wafadrive Information Sheets ~ Sinclair ZX Spectrum

As shown. In good overall condition.

A brief history of these:

They were taken from a closed-down computer shop around 2008. The owner was also a distributor back in the 1980s and bought out the liquidated stock from Rotronics. 

I don't know if these were meant for the public or trade only. I had a couple of full sets (1-22 page) in the past but this is the last complete set. Some parts are single pages and others are multiple. The only other sets I have are incomplete (odd page missing).

I'm sorry but I do not know / can't remember anymore information than that. The only other interesting item that came with these was a Rotronics Wafadrive pre-production unit that was destined to be developed the Commodore 64. I donated this to the Centre of Computing History in Cambridge some years ago if you want to check with them.
