The MiSTeryNano is a port of the MiSTery Atari STE FPGA core to the Tang Nano 20k FPGA board.
The MiSTeryNano is a work in progress. Current features are:
- Atari ST/STE
- Complete Atari ST/E chipset
- ST or STE configurable
- Cycle exact 8 MHz 68000 CPU
- 4MB RAM, optional 8MB STRAM
- color and monochrome video via HDMI
- YM2149 and STE DMA sound via HDMI
- Blitter
- Supports most TOS versions
- Full IKBD implementation
- Mapped to USB via BL616 MCU
- Mouse and keyboard via USB
- Joystick via USB or dedicated IO pins of Tang Nano 20k
- Floppy disk images
- Read and write support for drive A: and drive B:
- Images stored in .ST format on regular FAT/exFAT formatted SD card
- ACSI harddisks
- Read and write support for ACSI 0 and 1
- Tested with AHDI, PP's driver and HDDriver 12.03
- Images stored in .HD format
- MIDI
- Physical MIDI-IN and OUT
These videos primarily document the progress during development:
- MiSTeryNano #1: Is the Tang Nano 20k the cheapest and smallest Atari ST?
- MiSTeryNano #2: Booting TOS 1.04 for the first time
- MiSTeryNano #3: We got a rainbow!
- MiSTeryNano #4: Drives and Blitter
- MiSTeryNano #5: Playing Atari ST Frontier
- MiSTeryNano #6: B.I.G. DEMO
- MiSTeryNano #7: Tang Nano 20k running Atari ST Oxyd2
- MiSTeryNano #8: Atari ST with USB keyboard and touchpad
- MiSTeryNano #9: Tang Nano 20k as USB host
- MiSTeryNano #10: New OSD for the FPGA Atari ST
- MiSTeryNano #11: Advanced SD card for FPGA Atari ST
- MiSTeryNano #12: Atari ST first boot from virtual hard disk
- MiSTeryNano #13: Atari ST in Tang Nano 20k FPGA running Cubase 3 from Harddisk image
In order to use the MiSTeryNano the following things are needed:
- Tang Nano 20k FPGA board to run the MiSTeryNano core
- M0S Dock to connect USB keyboard and mouse
- a breadboard to wire everything up
- some jumper wires
- a USB-C to USB-A adapter to connect regular USB devices to the M0S Dock
The installation of MiSTeryNano on the Tang Nano 20k using a Linux PC is described here. Instructions for Windows will follow later.
You can use the on-screen-display (OSD) to change disk images. The F12 key will open the on screen display.
Since version 1.2.3 the MiSTeryNano exposes physical MIDI IN and OUT to be used with appropriate interfacing (output driver + resistors, input via optocoupler).
A digital DB9 joystick can be attached directly to the board.
