Hello amiga world: Have a general question: What would you all think of a product that would plug into an amiga 2000 slot, autoconfig, and provide you with 2 - 8 bit i/o ports, 1 - 16 bit i/o port, with built in A/D converters. The board would most possibly be used by amiga hardware hacks, musicians (full 16 bit sampling, compact disk quality), and general users alike. The more general applications would be the followup product line of amiga based hardware addons that work with the board; I.E. Amiga voice mail box, the 16 bit interface with drivers for full 16 bit sampling, switching devices, etc. I have been recently researching this type of hardware product, and have found that the only decent choice currently available, is the Proto 40K board, available for around $1700.00 dollars or so. Well, that is a bit high for the average Amiga user, I was thinking for on the lines of $250-$300 for my board. So, what do you all think?? Please send any response, Pro or Con, and we'll take a hard look at your comments. Thanks, and see ya all later. Mike... Disclaimer: This project is in no way related to SWBT or its subsidiaries.

Please send any I believe that a good portion of this cost is due to the fact that ACDA, the manufacturer of the Proto 40K, gets their D/A, A/D, DIO circuitry from a company called DataTranslation. DT makes boards for PC bus, MicroChannel, and Mac NuBus. They make a fairly high quality board which consists of the epoxy encased D/A, A/D DIO module and then the necessary interface circuitry on the remainder of the board. ACDA's price is not that unreasonable considering how few/small the market is for the Amiga. I am somewhat unimpressed that their board only goes to 40K. I would really like to see a 200K 16 A/D channel, 250K 2 D/A channel with 16 or 32 bit DIO. I mean thinking about how much bandwidth the Amiga can sustain with a disk drive compared to the PC makes me wonder why with the specialized hardware at our disposal the Amiga couldn't put together a blazing interface board. For $250-300, I think that you certainly could do such a board, but I think that you may find yourself expending a lot of effort trying to make the sampling relatively noise free. The DataTranslation boards have about a 10/4096 ths of a volt noise when sampling the zero volt signal. (this is their 12 bit board on a PC AT. and works out to be one least significant bit) Well, this is just my 2 cents. Go For IT! When I get out of school and into a real job, I would like to have the choice to use the Amiga for Audio sampling and synthesising. -- Bill Murphy murphy@newton.physics.purdue.edu
