Thanks everybody for the suggestions, very interesting reading, keep the ideas coming.
One of the objectives of a new production run of A1200 hardware would be to keep Ebay prices in check at a sensible level and to provide quality readily-available hardware with a warranty.
I honestly don't think that a RAM card could be commercially viable at under £50 due to the high tooling costs of the trapdoor connector for a relatively small run of cards. Although a good quality accelerator for WHDLoad purposes is a better idea maybe?
We wouldn't want to commission old designs from previous manufacturers- it is better to manufacture new progressive hardware (as per ZorRAM
) using modern components and design techniques.
