Hiya, Not sure which specific chip is used in the drives (not owning one) but the reading and writing is done through the command channel, hence CMD DOS must know about device. If you need the chip protocol I'd expect some disassembly is required and you'll need to find the memory map location for the RTC. Regarding the SmartMouse, the protocol is different for this device. Alan Dickey once sent me a driver so I could examine the source... I could forward it on to you. There is a Joystick port device which uses the Dallas SmartWatch chip available on the internet with GEOS driver. The chip is quite expensive (one guy tried to sell me one for US$30). If you wanted to go the generic route the RTCs used in AT machines or higher would be cheaper and more readily available. This is the DS1287 or DS12887 chips. You could also go for the older MC16818 RTC. Personally I gave up and used the clock on 64HDD ;) - Nick -----Original Message----- From: MagerValp [mailto:MagerValp@cling.gu.se] Sent: Sunday, 28 October 2001 6:14 PM To: email@example.com Subject: RTC There are a lot of CMD units with RTC chips in them and I'd like to hack together my own compatible unit. Does anyone know which RTC is used and how it's addressed in the different units? Especially the SmartMouse' chip would be good, a small joyport dongle should be easy to make. -- ___ . . . . . + . . o _|___|_ + . + . + . .
