So a couple days have passed, and I have some news.
As I've said, Holger has been working hard finishing an awesome piece of code to run a single chip High Density solution for Darklords' STacy.
So it is not to rain on the latest product release from Exxos for his ultimate logic based hardware step rate corrected, Dual drive supported HD modification.
Darklord encountered a stability issue with the logic configuration of a successful HD FDD mod I supplied him. The simple design has served many for years
. Exxos uses the same chip for frequency switching.
It didn't work for Ron at first, but eventually worked fine after his apparently dud WD1772 got changed, and we gained another working conversion.
Until it got hit with the awesome power of the PAK030!!!!!!!
,, this little board then caused an odd issue that crashed the machine (STacy) reliably.
Major PITA dude. The design is honest.. but could be described as brutish in the switching arrangements. There has long existed, few alternatives.
Holger bounced to the rescue (again) and offered a really tight HD mod using a single GAL chip. I would be the beta tester, and Ron the victim. GALs are cool and available- looking at code imitating logic is weird.That- in reality, emulates and expands on the hardware logic of the Exxos mod. Everything is clocked together and neat. It is a compact piece of awesome!
The code is ready and tested, and some workable pcb ideas thrown about. A mate should be dropping a full toner cartridge off to me this week so I can print some CAD to etch a pair. Yay.
I really don't know if anything commercial will come of this.. Exxos has something good to sell, and anyone should consider it. This mod is for Darklord right now.
Now the bad news.. My 2TB drive in the workshop computer keeps 'chirping' again!!! Was only a few months back the system drive did the same thing, and almost fell over.
And barely a year since the 2TB was purchased...
The bios still gets amnesia and forgets which drive is bootable occasionally, meanwhile losing the RAM settings. No the battery is fine.
These troubles won't hold up the mod going out to Ron. Just more dramas for my bench to endure.
Never a dull moment.
