After a bit of asking around, and with subsequent upload assistance from @fogWraith and GuiBer (on the Garden), I'm pleased to announce we now have functional copies of the floppy drive diagnostic utility, DriveTech on Macintosh Garden: http://macintoshgarden.org/apps/drivetech Functionality...

Iomega was pretty inept to have only put the front two LEDs into the documentation:

While a sealed-in-box defect isn't entirely outside the realm of the impossible, I would speculate that is unlikely. And I doubt bad caps are the culprit either. The most likely explanation is that the previous owners (in the plural, no doubt) threw the thing around quite a bit. That thing...

@phipli I have the same exact USB model Zip drive, except mine is functional and doesn't have that oddball LED flash in back... I plugged the stock AC adapter into mine and the USB cable into my iMac and left it for 3 hours, not inserting a disk once. I then aimed my UTi260B thermal camera...

I just wanted to reconfirm because in your opening post you mentioned having applied solder to the connector, but now you feel you cannot rule out the fact that the solder you applied wasn't perfect. In other words, it could be soldering of that connector, or it could be a "questionable"...

@mac27 So if it wasn't bad soldering of the power connector on your previous DC power board, then it must have been a fried component on it. Very interesting.

Exactly. So even if you were to connect some really fabulous audiophile-grade speakers to the headphone jack on your Mac, the audio the Mac produces is still limited by that sampling rate. That's why I don't think it would matter if you replaced all the caps in the audio circuit with tantalums...

@BeigeBoxSC The previous two posts offer excellent advice about voltage doubling for "SOLID" tantalum capacitors. Polymer Tantalum offers lower ESR, a benign failure mode (doesn't fail shorted), but at a significantly higher price. These days, I use OS-CON wherever possible because they cost...

I just watched your video. Very interesting. I’ll tag @David Cook since you linked to his 68kMLA post. Some video cards like Radius required their driver to be loaded as an extension in order for the card to work as intended. Other cards didn’t have such INITs. So I am wondering if there is...

Please forgive me for the multiple confirmations below, but people know me here as a MAN OF DETAILS. I like to confirm the important things when relevant. After having spent countless hours through the years with various benchmarks, I can attest to the fact that System Software version does...

I just added Speedometer 4.01 with more useful Machine Records to the Garden page just now. I am using that 4.01 version to run my Benchmarks. That way I can compare my results to yours in a meaningful way. Below are my Norton System Info 3.2.1 benchmarks, setup in the same way as yours (in...

@zigzagjoe I found your 68kMLA post where you mention "Speedometer 4.01" and then link to this page on Macintosh Garden, but that page only offers 4.0 and 4.02. So I will assume you meant to say "4.02" and use that in my testing. Anyway, I did find Speedometer 4.01 on one of my old hard...

@zigzagjoe Thank you for another detailed and extremely helpful reply! Your mention of using Speedometer 4.01 and Norton System Info 3.2.1 will allow me to use those two versions with my PDS-edition DiiMO and Synchr030 setup (and later my CPU-socketed PowerCache), so I can make better sense of...

"System bus" via CPU data transfers, you mean? I ask that question because in terms of the opening post's CPU score of 9.83 (in Speedometer 3.??) and my DiiMO's score of 10.42 (in Speedometer 3.23), I am curious if my DiiMO being faster than the Booster boils down to my use of Synchr030, or...

Thank you very much for your kindness in confirming that not only do Tetris and PoP sound great, but that Sound Manager is no longer an issue on the v2 Booster! I am aware of the 180Ω pull-up resistor mod (for the Booster) that is necessary to put your Booster card on top of the Synchr030. Wow...

@Ubik I read in that 68kMLA thread there were audio issues that pertained to the 1st edition Boosters like yours. Would you mind testing the following 2 games to see if the stock SE/30 audio (without Booster installed) sounds the same or different than with the Booster installed? 1. Spectrum...

Unfortunately, I don't have a schematic of the VRM to know which pins are what. Knowing that is very important if one wishes to test the VRM outside the Cube. But you're right, it does make good sense to test it outside the Cube if you are able to find out how to properly identify the voltage...

I talk about that from 53:14 in my video below, which pertains to the SE and SE/30...

Believe me, I've spoken to Steve Chamberlin about this via email and in the comments section of the FloppyEMU page for many months. Even though "it has nothing to do with Intel vs. Apple" in theory, I can tell you from PRACTICAL EXPERIENCE that it actually does have very much to do with an...
