HEPAX and CCD - Conflict of Interest? - Peter - 04-19-2005 Hi, I have a CX halvenut with a Hepax (1D) and a CCD (B) as I love the direct access to System registers via CCD yet I'm alos playing with m-code. However the Hepax has the annoying tendency to simply dissapear from Cat 2 every so often. Unplugging it and replugging it into different slots, unplugging CCD etc eventually brings it back (with memroy lost naturally, how convenient, 'Goto "Key in 500 m-codes again", do not go over start, do not collect 200'...). I wonder if there are any incompatibilities with the CCD that cause this to happen. I read that the early/beta versions of the HEPAX had some internal problems yet I thought by version 1d that should have been resolved... Anyone any thoughts? Thanks so much in advance! Cheers
Peter
Sell the Hepax on ebay and buy a Clonix Hepax module - John - 04-19-2005 The clonix NoVram Hepax module does not lose it's contents when unplugged.
You might even make money selling the Hepax and buying a NoVram module.
Re: HEPAX and CCD - Conflict of Interest? - Raymond Del Tondo - 04-19-2005 Hi Peter,
does the HEPAX disappear completely,
You know that the HEPAX moves itself
Then you'll find the CAT entry *only*
From my experience, the HEPAX and CCD modules
However, I have to admit that I only used the NoVRAM
You could also try another approach:
Another complication could happen if you plug
And of course the general tip:
Raymond
Re: HEPAX and CCD - Conflict of Interest? - Ángel Martin - 04-20-2005 I think Raymond's last observation is the issue: if you plug in the CCD *after* the HEPAX has been previously initialized, then it is more that likely that the XROM ID's assigned to the HEPAX RAM would conflict with those of the CCD (i.e. 9 and 11). This is trivial to correct: using HEXEDIT change the first word of those RAM pages to non-conflicting id's
Best, Re: HEPAX and CCD - Conflict of Interest? - Peter - 04-21-2005 Thanks guys, I'll try all those things out. As for some of the questions raised: The strange thing is that it works for a while all fine and then suddenly disapears. As I was programming my own rom, one issue could be that I used the wrong XROM numbers (despite trying to pick a free one...) Anyway, I'll apreciate all the info and let you guys know how it goes. Ah, one more question - Raymond mentioned this one thing, that makes one laugh, what was it? - called reversehigh, Rueckenauf, ah, no: backup! That's it. What kind of advanced technology is that???

Re: HEPAX and CCD - Conflict of Interest? - Peter - 04-23-2005 Thanks to all involved I was able to fix the issue it seems. And Osram's razor stroke again - the contacts were dirty and caused the "wackelcontakt". Some alcohol and TLC fixed it, to my utter delight! Thanks again for all your infos, I also learned something about the right sequence of plugging those things in! Cheers peter
