Turbo card working with CDTV Amiga in CDTV mode

I would like to greet everyone.
Im new here and this is my first post

I have a question for everyone. I am looking for a card with at least 020 processor for Amiga CDTV.
Which would work in both A500 and CDTV mode.
I know there were also some T30 prototyp with a 020 / 28mhz processor and 8mb fast ram but I don't see such a card anywhere at auction.

Greetings to all and thank you in advance for your answers.

long time ago, i have installed a main 68020, but the fastram not auoconfig and i used addmem, next time sold

like this AMIGA 500 MTEC 68020i


Matze on a1k.org make some card with 68010 and fastram working on cdtv

So this card (AMIGA 500 MTEC 68020i) below could work in cdtv mode. Only this card is not on sale. I found one offer at auction but the price is very high :-(
Maybe there is some open source design of this card for own construction?

And these two below card, did any of you test the Amiga CDTV in the CDTV mode?

1. Terrible Fire 534
2. 68030TK on Matze

i have sold outside amibay my mtec for <Snip> last year

Piacc64 is a very good price for this card. Does anyone here have such a card for sale or a similar one working in CDTV in CDTV mode?
