Faster, but not "much faster". Depending on where you were writing it could be as low as 300 bytes/second. You're starting to cut close to the margins, especially if the C=64 is having to also manage the modem communications at the same time. So yeah, doable but that's about the max you can expect out of the hardware. A 4800 baud modem would be right out.
- leptons 1y agoThe C64 doesn't control the disk drive directly, the 1541has its own CPU, about as powerful as the C64. > A 4800 baud modem would be right out. Not with a "Warp Speed" cartridge. It does write speeds on a stock C64/1541 up to 2900 Bytes per second. I'm pretty sure reading serial data faster than 2400bps is easily doable too. https://www.obliterator918.com/the-warp-speed-cartridge-from-cinemaware-is-nice/ https://www.obliterator918.com/the-warp-speed-cartridge-from...
- rasz 1y agoModern 1541 turbo, like Krills Transwarp, tops out just shy of 20KB/s on unmodified hardware https://csdb.dk/release/?id=214786 https://csdb.dk/release/?id=214786 with steady 16KB/s in normal use https://www.obliterator918.com/benchmarking-transwarp-the-insanely-fast-1541-loader/ https://www.obliterator918.com/benchmarking-transwarp-the-in... The trick is encoding files in special way to minimize drives CPU load.
