Hi Peter and all, I would highly prefer (D) the Internal interface, replacing a microdrive, wich seem to be fast and well integrated. If a such device exists, i would be interested for 2 or 3 units for me. If this project starts one day, I may help for a driver adapted and derivated from Qubide wich i mostly re-wrote for my own usage after I have managed to do a working prototype for an Expander for Qubide.
The (B) External interface, plugs into QL ROM port, can also be enough good for me if exists but no idea how complex is hardware nor driver. I would be very happy if a such project can born for the QL community scene.

I can _not_ promise to really make a piece of hardware available, but it would be nice to know, just in case... A) External interface, plugs into parallel port of SuperGoldCard Pro: - Interface also works on Q40 and Q60 - QL Case doesn't need to be openened - Easy reconnect from one machine to another - Hot-plugging might work - ROM-Port remains usable Con: - Slow data transfer through parallel port handshake lines B) External interface, plugs into QL ROM port Pro: - QL Case doesn't need to be openened - Faster data transfer - Onboard Driver ROM - Works on QL without GoldCard / SuperGoldCard Con: - ROM-Port occupied - Complex hardware C) Internal interface, plugs into CPU socket Pro: - Fastest data transfer - ROM-Port remains usable Con: - QL Case needs to be openened - Only GoldCard/SuperGoldCard machines D) Internal interface, replacing a microdrive(!) Can easily be bolted inside the case, after a microdrive was removed Plugs into CPU socket or maybe other place Pro: - SD/MMC-card can be plugged in like a cartridge - Looks cool - Very "QL-style" - ROM-Port remains usable Con: - QL Case needs to be openened All the best, Peter _______________________________________________ QL-Users Mailing List http://www.q-v-d.demon.co.uk/smsqe.htm _______________________________________________ QL-Users Mailing List http://www.q-v-d.demon.co.uk/smsqe.htm
