It seems almost entirely pointless: the SB 1.0 has a big place in history but that's due more to market share than technical excellence or uniqueness compared to, say, the C64's SID chip, or even a true contemporary like the Gravis Ultrasound.
And unless I'm mistaken vintage Sound Blaster boards are not exactly in short supply... though I'm not entirely sure about that; it's tough to search for them thanks to the countless scads of products bearing the "Sound Blaster" moniker.
And yet, this is cool. This is a complex piece of work, a very nice piece of engineering by the look of it!
Preservation of computing and gaming history is important, and ensuring we can make more physical copies of things if needed/desired is crucial when it comes to keeping that history alive.
