Jan 3 at 21:55 | comment | added | Greenonline | There might not be any empty IC slots: "There is anecdotal evidence that 48K machines that failed factory testing with faulty upper RAM were packaged and sold as 16K models. Open the machine up to check first – if the upper RAM is present and not socketed, then a repair of the faulty RAM is more appropriate, and will be covered in another article." - Source Upgrading a 16K Spectrum to 48K. What isn't clear is whether an external RAM pack would work, in this case. Would it "switch out" or "page out" the bad 32k RAM? | |

I purchased mine for £24.95, installed it myself, and marvelled at the difference in the simulated speech in Meteor Storm (Incomprehensible with 16K, clear in 48K) | |
