 Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me. |

Wondering if anyone can recommend a product that is known to work. I tried one of those USB types, some years ago but it was flakey as heck. |

I'm not exactly sure what you mean by "upgrading", but are you familiar with this?: https://www.gotekemulator.com/Gotek-Floppy-Drive-to-USB-Emulator.html These are available with modified firmware and pinout to fit many systems. For example, there are also modified firmwares for the Amiga (so that the device can emulate 880kB and 1760kB Amiga drives and floppy disks).  If you search on Google, you might find DIY projects on GitHub. I vaguely remember something about the Pico as well...  Greetings. |

The Gotek is generally considered to be very reliable once it's set up right. Of course, the settings have to be correct for the disk controller in the machine. Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |

Gotek: Depends on the system. I tried a Gotek in a HP54622D scope, and that was not succesfull, since it could not save screenshots as BMP, only as TIF. And they did not save as a file on the USB, but packed inside an .img file. At that time Windows could not open the .img (a floppy image). Linux could. But it was so clumbersome that I purchased a second hand floppy drive, and a USB floppy disk to attach to the PC. Volhout P.S. and I almost fried the scope since there was 12V on the 26 pin cable from the scope. And 5V logic does not like 12V. PicomiteVGA PETSCII ROBOTS |
