Are folks completely unable to use Google anymore? Here is what I'd do, go to the website I provide below and learn what you can. I'm pretty sure you need to xfer the DAT files into a format that is usable by today's players - maybe FLAC is your best choice for this.
Then get a PC with a couple of big external drives - one for the files and the other as a mirror - and begin the process of loading the converted DAT files onto the drives.
When that is done, use a PC-based player to playback your files. Not too difficult but it will be a bit time consuming. And I don't think you need to spend $5k, you could do all this for around $3-4k...
