For anyone that needs a clockport soundcard this could come in useful : http://ludens.elte.hu/~vf/ , the VSS.lha file on Aminet also contains information and some details on how to *roll your own*. I've seen this before , but someone on a.org got an e-mail from the author addressing isssues like pricing so i thought it would be useful to paste it here :) :

Hi! > Could you say me the price of the VF Sound System?
> How can i get one of this interesting thing? :))

The price will be about $100.
But I will produce it again, only if I get at least 20 serious
orders. I will re-design the pcb to fit to the Buddha card too, and substitute some components with newer, better ones, maybe add new features.
I never sold anything outside Hungary, so I don't know the available payment and shipping methods.
I you have any idea, or can help, please write me. I don't have world-wide customer service :) (Yet ;))

> Do I need a tower? more info plz!
A1200:
Tower is not required, but the internal shielding plate must be removed. Also the HDD may not fit too. If you have FastATA, it must be shifted with some 40-pin precidip sockets.

Buddha:
The clockport is unfortunately too near to the Zorro socket, the card can't fit. A short flat cable with suitable connectors at the end is required. (2.5" IDE cable will be fine)

I do not post any, because I don't have time to read them either :( But somebody else posted one article to the Czech Amiga News.

Nobody can avoid all mistakes, but I will do my best, of course. I sold about 20-30 pieces in Hungary, except the initial problems with the early versions, all works fine. Never saw any hardware incompatibility problem. A basic A1200 is really too slow for 44kHz AHI mixing, but the mp3 decoding works fine.

The only known hardware problem: If the clockport speed is too high, you can't use sampling frequencies below 22kHz, and mp3 below 32kHz. Buddha/XSurf is sometimes too fast, the speeded-up internal clock port either. (The clockport speedup doc is included in the archive, but currently only in hungarian language :( For these low-quality modes you may use the motherboard sound system instead, it uses 16bit DMA, much faster than the slow 8 bit, CPU- controlled RTC port.
