[retrocomputing devroom] Submission : ZX Spectrum in the new Millenium

Hi, I have made a submission for a talk named: ZX Spectrum in the New Millenium Upgrade ROM to 512K This documents the process of defining a larger Cartridge System that is retro compatible with existing original hardware. I'm not sure if this will be squeezed in a 15 or 50 minutes talk, depending on slots availability, but would like to know with some time to spare, so that presentation can be adapted depending on which will be available. I'm not sure exactly when or where the acceptance (or not) of the talk will be available. Can someone give some pointers on these issues ? Regards Rui Martins
