No worry James, Now I have Satanic SE/30I normally use this 100% (not 99.9%) version sold on Amazon Japan:
Amazon.co.jp: 100% Isopropyl Alcohol 500ml IPA 2-Propanol : Industrial & Scientific
Amazon.co.jp: 100% Isopropyl Alcohol 500ml IPA 2-Propanol : Industrial & Scientificwww.amazon.co.jp
But for the bathroom dunking shown in my Part III video, I did use this 99.9% stuff:
No, there's no noticeable difference once you get past 99%. Just don't use the 70% rubbing alcohol because that has a fair amount of water in it.
In the past, I used Anhydrous Ethanol, but it tended to leave a film, so I switched to IPA.
I'm not sure if this discussion helps Zane, or not, but I just wanted to clarify.
Zane, your work on this accelerator is amazing. If it works without distorting the sound, you will have done better than Levco SuperMac! Honestly, I don't know how they released a product with distorted sound though. I can't remember if there was customer outcry over that back in the day. I do know that @Kay K.M.Mods is not a happy camper about the distorted sound when using his Carerra040 on his SE/30. A big part of the Mac experience is sound, so it's important to get that part right, in my opinion.
The Turbo 040 I bought the other day is also broken, and any further investment in the SE/30 seems wasteful.
Instead, I would like to support Zane's project It's completely different from other clones. If there is a pre-sale, I will buy it, and I think there are many people who donate if the funds are tight. Of course I too.
