Same. As far as I know, though, the black PS1 didn't actually do anything special to enable development, it just allowed Sony to arbitrarily make the devkit incompatible with retail PS1 consoles. It still required a special memory card dongle and boot disc in addition to the special console model for some reason. I seem to recall that someone cracked the boot disc to run on retail consoles without the dongle, and the serial link just needed a level shifter like a MAX232 (though these days you'd probably use a USB UART like CP2102 or FT231).
