Re: ZX81 clock, but this one is different !
well as long as they are not glass or ceramic platters (usually only found in higher spec drives) they will most likely be aluminium in which case they'll never shatter if you do find yourself with a glass or ceramic platter i guess a fine diamond dust cutting wheel might do it if your very careful ...

Re: ZX81 clock, but this one is different !
a couple of videos for you... normal ruinning mode, sorry about the flickering, it's the mismatch in camera shutter speed and refresh speed of the POV clock, much like when you try to video a tv and get black bars. http://www.youtube.com/watch?v=VICIvcE9U_0 http://www.youtube.com/watch?v=NV5Zj8m4e18...

Re: ZX81 clock, but this one is different !

Re: ZX81 clock, but this one is different !
i cut the platters with a dremmel, the vibration is very smal as long as you get the slots opposite each other, they counter balance each other :D but one thing whne selecting a hard drive.... i found that after ripping out the heads and voice coil that after a while maybe 30 seconds or so the spind...

Re: ZX81 clock, but this one is different !
Well that was a nightmare... decided as my code was growing to split the source up into modules... and added a few tweaks along the way, i think that was my downfall, i should have just split it and re-tested it before doing the tweaks. my i2c bit banger is ugly as heck, it was nice and readable ful...

Re: ZX81 clock, but this one is different !
ah ah... it's not that i particularly want it to go faster, i write code in a very haphazardous way, commenting out sections and putting in new bits, then when i am happy with the results i sit down and tidy it up, add more comments to make it easier to understand what is going on and delete all the...

Re: ZX81 clock, but this one is different !
Well it works, i can tune it off and come back to it some time later load up the program and have the correct time displayed :D still tweaking the code before i start adding extra display modes (when i can tihink of them) first bit of code that i'm trying to optimise is this BCD_TO_A LD D,A ;SAVE TH...
