| # VIC20Nano on Tang Mega 60K NEO | ||
|
|
||
| VIC20Nano can be used in the [Tang Mega 60K NEO](https://wiki.sipeed.com/hardware/en/tang/tang-mega-60k/mega-60k.html). | ||
|
|
||
| Besides the significantly bigger FPGA over the Tang Nano 20K, the Tang Mega 60K adds several more features of | ||
| which some can be used in the area of retro computing as well. | ||
|
|
||
| Although the Tang Mega 60K comes with a significant ammount of | ||
| DDR3-SDRAM, it also comes with a slot for the [Tang | ||
| SDRAM](https://wiki.sipeed.com/hardware/en/tang/tang-PMOD/FPGA_PMOD.html#TANG_SDRAM). Using this board allows to use the same SDR-SDRAM memory access methods.<br> | ||
|
|
||
| The M0S required to control the VIC20Nano is to be mounted in the | ||
| **right PMOD** close to the HDMI connector with the help of the [M0S PMOD adapter](board/m0s_pmod). | ||
|
|
||
| Plug the optional Dualshock [DS2x2](https://wiki.sipeed.com/hardware/en/tang/tang-PMOD/FPGA_PMOD.html#PMOD_DS2x2) Interface into the **edge PMOD** slot.<br> | ||
|
|
||
| The **SDRAM 1** slot is allocated for a digital retro Joystick interface. | ||
| A 40 pole 2.54mm pinheader need to be soldered into the Meag 60k NEO. | ||
| An 40 pole receptable to be used connecting the 7 signals to the D9 connector. | ||
| > [!WARNING] | ||
| > Joystick interface is 3.3V tolerant and therefore the Joystick 5V supply pin has to be left floating when no level shifters are in use!<br> | ||

|
|
||
| The whole setup will look like this: | ||
|
|
||
|  | ||
|
|
||
| The firmware for the M0S Dock is the [same version as for the Tang | ||
| Nano 20K](firmware/misterynano_fw/). | ||
|
|
||
| On the software side the setup is very simuilar to the original Tang Nano 20K based solution. The core needs to be built specifically | ||
| for the different FPGA of the Tang Primer using either the [TCL script with the GoWin command line interface](build_tm60k.tcl) or the | ||
| [project file for the graphical GoWin IDE](vic20nano_tm60k.gprj). The resulting bitstream is flashed to the TM60K as usual needing latest Gowin Programmer GUI 1.9.10.03 or newer. | ||
|
|
||
|
|
||
| **HW modification** | ||
| [Tang SDRAM Module](https://wiki.sipeed.com/hardware/en/tang/tang-PMOD/FPGA_PMOD.html#TANG_SDRAM) V1.2 modification to fit on the TM60k NEO dock.<br> | ||
| The capacitors are a bit too lange and touching the 60k FPGA plug-module. | ||
| Use duct tape to cover the capacitors avoiding shortcuts or unsolder three that are blocking. | ||
| There is a also newer Version 1.3 of the TANG_SDRAM available (90° angle) that likely fit. | ||
