The SX-64 cartridge port is connected by a ribbon cable, which increases capacitance between the bus lines. I don't have personal experience, but I've read anecdotal evidence that some cartridges do not work on the SX-64. > My UK/PAL SX-64 seems to display the AR boot screen but hangs after > pressing F7 for Fastload. > > However (here's the weird part), sometimes it works OK and drops into > BASIC without any problem. Very odd. Could it be that when you enable the fastloader, the cartridge installs an interrupt hook, causing the cartridge code to be fetched several times per second? That would increase the probability of a crash. When the cartridge is not accessed, it won't deliver garbage data to the bus. > I also have a Lazer/Freeze Machine cart which works fine in the SX-64. How old is your AR? The oldest versions had several chips, which could place more load on the bus. > I've got several AR freezed programs on disk. Most load fine but some > lock up after loading.
