Howdy,
I had this old Digitech RP6 that I bought in '96 and I've been wanting to salvage some of the parts. Seems like a gold mine compared to my small amount of inventory. Spent several hours reading data sheets and trying to figure out how things are supposed to work. Here are some of the more interesting chips on the board.
PCM54HP 16Bit dac
Z80 (sweet!)
D41464 Dynamic nmos ram
5532D dual op amps (supposedly low noise high quality)
Some kind of DSP by Harman International
A couple of questions for the dumpster divers.
What is the best way to unsolder some of these surface mount chips? From what I've read, keep the soldering iron as low as possible. Sometimes the data sheet will have the maximum time for the soldering iron to be in contact with the component... and sometimes it doesn't. I've seen tips for the soldering iron that span multiple pins. I would really like to be able to use some of this stuff, that DAC is $30 on mouser. Well... that one is in a socket.![Big Grin :D :D](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
anyway,
thanks for spreading the knowledge.
