Super rare variant. collectors would bight your hand off, I have yet to see this on the market for sale, and if you could ensure collectors know, I would expect nothing less than 150GBP plus!
PLAYINGNot that it can be played really...I actually owned one of these in 1984, it cost my parents ?12.99 and the shop had to order it in, I remember it came in a brown shipping box that perfectly fit the cart, and the manual was Videopac manual size but fat. anyway, it soon got shelved as you spent hours typing in the most rudimentary of operations. and then you ran it, and then you switched off as you couldn't save your work in any way as the cart had no battery storage and it wasn't until the BASIC module arrived that programmers could save their work.
