Re: WP-34s: Missed key strokes? Message #5 Posted by W. Bruce Maguire II on 16 Apr 2012, 4:20 p.m., in response to message #4 by Marcus von Cube, Germany
Marcus:
Thank you for the detailed response.
Unfortunately, I don't have a cable. I just e-mailed Gene. I hope that he still has some available. If not, are there schematics such that I could make one?
I have access to both another WP-34s (due to my greedy/excited response resulting in the purchase of two), and I also bought a spare 30b from Amazon, so I will definitely perform some experiments.
I don't believe it is a problem of keystrokes filling the buffer, because it can happen on the first or second key-press. It seems to me that it is either flaky hardware, or a FW architecture that can miss a quick keystroke. I'm getting the impression that the FW is not at fault---otherwise many people would be complaining about what I'm seeing.
I know that you have probably heard this many times before, but I want you to hear it again: To you, Pauli, Walter, Eric, and all the others who have invested serious time into making the WP-34s a reality, I owe a *HUGE* debt of gratitude! I haven't followed the MoHPC forum for 10 years---because of the sad decline in HP calculators---but I am now greatly excited about the WP-34s and the other custom-HW / custom-FW offerings! I've worked with enough embedded-FW people to realize the effort involved. I'm heading over to the donation page on Sourceforge right now. You guys have really made a mark!
