#PARALLEL TO SERIAL CONVERTER DIAGRAM SERIAL#
The serial line uses a fixed physical protocol at 19200 Baud, 8 Bit x chr, 1 Stop bit, No parity and it can be any system capable to support a serial RS 232 communication. I found at least one project ( CBM PI1541) with that approach. In other words the program acts as a converter of a parallel printer into a serial printer. The TxD line, pin 3, CTS line, pin 8 and the DSR line, pin 6, of the serial port, are used. Use the I/O ActiveX control for serial and parallel communication. It converts a serial 2400 baud signal into a parallel signal. Serial and Parallel cable schematics and wiring diagrams. This converter may help if just the serial port on a personal computer is free, whereas the printer needs a parallel (Centronics) port. Today, PCs don't come with a parallel port, and the USB-to-parallel converters don't offer the same flexibility as an in-built parallel port, so the modern equivalent would probably be a RaspPi or something similar with a level converter, and a port of the software. Serial-to-Parallel Converter Schematic Circuit Diagram. Special software on the PC driving the IEC bus through the parallel port could then emulate a floppy, so you could transfer data. But then you need special software (and today, also special hardware) on the PC side.īack when all PCs had a parallel port, a simple self-soldered cable called X1541 cable was all that's needed. However, you can use the IEC bus on the C64 (where normally the 1541 Floppy is attached) without modifications on the C64 side. General description The 74LV165A is an 8-bit parallel-load or serial-in shift register with complementary serial outputs (Q7 and Q7) available from the last stage.
Signals can be easily stored and transmitted in digital format but in order to be recognized by human or non-digital systems it should be converted to analog. Here the input is given in terms of 8 bit digital data to DAC and output is to be an analog voltage. The C64 does not have a RS-232 port, so you cannot use a standard RS-232 adapter on the PC side without having some hardware and software on the C64 side. A digital to analog converter is a device which converts digital data to analog signal.

Is it possible to transfer text or files from PC to C64 without any software on the C64 side, using similar method as on 8BitGuy's video? If so, how to do it?
