1818-2295A dump has been uploaded to ko4bb site, probably there's need to be moved in the right place before it's available. On Mon, Oct 10, 2016 at 9:32 AM, Francesco Messineo wrote: > Hi Dave, > right, once I find the dumps, I'll upload them. > thanks > Frank

Hi Bob, I will send you my dump, but you have to wait at least until tomorrow evening. I'm not near my backups today. I can confirm that 2 x 28C64 (I used ST parts, so if you can scope your Atmels for glitch, I would be very much curious to see if they've the same problem) worked in my 59309A, but

Hi Francesco, That's wonderful, I hadn't dreamt that anyone has dumped out that ROM. If you can find your copy of your good 1818-2295A ROM it would let us avoid trying to fix the bit rot in the one I was able to read, especially as we don't know if the 1818-2295A exactly matches the tables in

I have a dump of the 1818-2295A somewhere, it should be archived in one of my backups. I also made a replacement with a board having 2 x 28C64 SO-28 eeproms and it worked in my 59309A as far as I could test it. However these eeproms present many glitches on the outputs during address toggling, so

Re: [time-nuts] HP 59309A Clock runs, sets via GPIB, but no GPIB output?

Bob, I just looked at the clock I am not using and it is 1818-2295A, it is not convenient for me to check the other one as it is running and in a place where I would have to disconnect it to get it out. I could dump this ROM for you but it may take me a few days as I have other things on

[combined replies to Paul, Tom, Mark and Pete below] Hi Paul, Thanks for the helpful suggestions. Yes, I spent a pleasant afternoon with the little 59309A, sides and bottom removed, 0.025 pins soldered on to the RAM, other interesting signals, and U2 the ROM. That makes it easy to pick any
