RetroMatic 2000 update 11: user interface prototyping

It’s now time to start prototyping the user interface for my RetroMatic 2000 box. As a reminder, the box will have two functions: a video converter to allow an 8-bit micro to be used on a modern monitor, and a USB stick floppy drive emulator.

The plan is to have each function controlled by a rotary-encoder (with a click button) with feedback via 16×2 LCD displays.

RetroMatic 2000 update 8: Jumpers! In an Adventure with Floppy Cables!

In my previous posts I flashed HxC firmware onto a Gotek USB floppy emulator, and tested it with my Video Genie.

I’m now going to delve into the intricacies of the Shugart 34 pin floppy disk interface (emulated by the HxC firmware); the jumper settings on the Gotek hardware; and how to extend the hardware to do some cool stuff :-)

RetroMatic 2000 update 6: HxC floppy drive emulator

The second part of my retro computer “helper” is to be a floppy drive emulator, to load files off a memory card or stick. This should be more convenient and reliable than physical disks. It will also allow me to transfer files to more modern computers.

My chosen floppy emulator was the HxC: it seems very well designed, and supports almost any format you can imagine.

RetroMatic 2000 update 5: user interface ideas

My RetroMatic 2000 project has two halves – so far I’ve been working on the first half: a module that converts a weird video signal from a 1980s computer to clean VGA.

Before starting work on the second half (a floppy drive emulator to load software onto these machines), I’ve been having a think about the final aesthetics of my project.
