[Questions] My CD32 adventure - TF USB riser and RGB

[nico7550]

Hi,

a few day ago, I found a video showing a dual port USB riser for the Terrible Fire:

I found a 3D model for the cover:
https://www.thingiverse.com/thing:4936943
I found the github page dealing with an experimental riser
https://github.com/terriblefire/cd32_riser
But cannot find any other trace of it.

I also find the Imperator CD32 riser with VGA/RGB/AUDIO OUT and SINGLE USB:

But didn't find a cover?

And I aslo found the Hefesto CD32 riser with VGA/AUDIO OUT and DUAL USB:

and the 3D cover: https://www.thingiverse.com/thing:3364994

So here are my questions:

I have a TF360 and I want USB, Should I go for USB riser or use adapter?
If riser, Imperator or Hefesto ?
Any shop? Or only when they appear on ebay or direct selling with the creator?

Last question, on the VideoGamePerfection RGB modding page (https://videogameperfection.com/products/cd32-rgb-modification/), they said:
'This modification produces significantly better visual results than the plug and play RGB output options such as SX32, Terriblefire etc. The problem with those modifications is that they route the RGB signal all round the CD32s board, picking up noise as it goes.'
What do you think?

Thanks

You can find some more information about the TF CD32 riser here:

(They sell PCBs in this forum. I don't know, whether these are still available.)

The riser is sold on Amibay in a bundle with a TF330:

I bought my riser from Steve Clifford. He has listed it in a bundle in his shop, but he sold me a single adapter on request:

Please note that you won't get full USB ports. Exxosforum says about the TF CD32 riser:

Specifications​

1. Buffered DB23 out​

2. Two USB HID ports with following support​

• HID Keyboard support
• HID Mouse
• Support for Keyboard+Mouse combo
• Support for standard HID Gamepad :
• In Joystick mode with 3 buttons
• In CD32 Gamepad mode

3. RTC - M6242 emulation - easiest way to set it up, and test is by using AmigaTookKit.​

The printing on the Imperator CD32 says: "USB KEYBOARD"
Therefore, I assume it doesn't support anything except a keyboard.

I don't know the Hefesto riser in detail, but I bet it also supports solely HID devices.
