hey there guys
as many are aware there is the known issue that some early/mid 90s macs
can have problems with the serial port communications; (such as the performa 5x00 series)
im just wondering, can anyone confirm for me that the quadra 630's serial ports
function on the same level of fantastic as other 68k macs
just because this is the sole reason for my interest in downgrading my performa 5200CD,
to achieve a better result with MIDI performance over serial.. as it is my Opcode 64XTC is unable to
stay synched as long as its connected to the Performa 5200CD's serial port (modem). it errors out then oms complains it cant see the interface any longer, and then if i power cycle the 64xtc interface again, it will see it again, but it has some type of intermittant problem, im guessing this is due to the serial port not being able to maintain a 1mhz connection (or whatever speed it is working at?)
it is of course a documented shortcoming of the performa
http://lowendmac.com/1995/performa-5200/
THIS page lists it as a problem specifically to do with "hardware handshaking"
im not sure of all the specifics
i just want to make sure whether or not the Quadra 630 is afflicted with the same malperformance..
because the parts are almost identical except for the cpu being powerpc vs 68040.
(the real quadra 630, not the LC models that came with 68040LC chip)
