Note that this is only for male DB-19s (i.e. for peripherals). Alas, you'll still have to hoard your battery-bombed vintage motherboards for female DB-19s. (Or hopefully use a physically different but electrically compatible connector...)
BMOF dropped over $10K into those connectors and even then I wondered why does he think he can recoup that. There isnt enough retro enthusiasts to sell enough Floppy Emu. Its been almost 10 years and sounds like he is still sitting at over 9K spares.
