Thanks for your all your suggestions about the video problems my friend was
having. It turns out that it was the 6502 chip itself that was the
problem! My question is where can one of these be ordered from?
Thanks in advance,
Chris
P.S. Please send replies to me directly as I don't always read the
list right away.GREYELF@WPI.BITNET (02/07/89)
To whoever needed a replacement 6502 cpu chip, (was it Chris @ brown?) A 6502 can be ordered from any of several major electronics parts suppliers, eg. Gerber Electronics. Or the person could go to a 65c02, with or without upgrading. Or the person could just get one of these accelerators: ZIP or Rocket, that replace the old cpu anyway. That way they also get a 400-500% speed increase. The chips are pin compatible, just put the old one out and insert the new (as I understand it). Can anyone support my assumption that electrically it won't matter if you just pull the burnt 6502 and put a new 65c02 in? +------------------------------------------------------------------+ | Michael J Pender Jr snail mail: Box 1942 c/o W.P.I. | | Bitnet: greyelf@wpi.bitnet 100 Institute Rd. | | Internet: greyelf@wpi.wpi.edu Worcester, Ma 01609 | | User #20 at H.U.G.E.

Actually, it WILL make a difference electrically. There will be less demand on your power supply, since the 65c02 requires considerably less current than a 6502. There will also be less heat generated by the 65c02. Other than that, no, it won't make any difference electrically. -Phil Albro-
