This is really cool. I'm looking forward to trying this out when I have some free time. Also thanks @cheesestraws for pointing me to this listing for a Data Cannon ROM v2.4 upgrade kit which also included MacinStor v3.2.5. https://www.ebay.com/itm/354631040717 All of the contents are attached...

A few oddities I'm accustomed to when acceleration is enabled alongside drag and drop: - Netscape Navigator draws 'Back' in every button across the toolbar. - Drawing dropdown menus more than once consecutively becomes garbled (e.g. open the control panels menu from the Apple menu, then slide...

This is an exciting project! Excellent work! As a reference point, I've hit a peak of 9.6MB/s using a 32GB SanDisk Extreme (120MB/s) > Stratos CF AztecMonster > Sixty Eight Thousand SCSI Bolt > IIfx (50MHz clock). Seems likely the SCSI Bolt is actually the bottleneck here since it's a 10MB/s...

Here's a couple pictures of the kit and a scan of the manual. Probably less practical than an oscillator swap in most permanent installations, but these are fun and pretty nifty for benchmarking.

The Sonnet/Daystar 100MHz version doesn't decouple from the host's bus clock, it switches from a 4x multiplier to a 3x multiplier to allow for use in 25MHz and 33MHz hosts. The 80MHz model with 72-pin SIMMs does have it's own decoupled clock, but apparently is nearly intolerant of clock...

I'll try to take some more detailed photos of this card next time I have the machine it lives in on the bench. Can't promise that'll be tremendously soon, but I'll push it up the priority list a bit.

A little goes a long way. It's a very low viscosity fluid, like WD-40 or water. I'd expect only a small immediate improvement, but quite a bit more with some careful exercise of the hinges over the course of 10-20 minutes. In my experience the trick is controlling the trigger so you don't drench...

I think the purpose and subsequent speed limitation of the FPGA is to allow the pins to be remapped, since the accelerator needs to be installed at two different 90° rotations on the socket to accommodate the different physical constraints on beige vs blue/white models.

I posted the two cards I found on my Truevision page: jeremywork.com/rd/rd_truevision.html

Did you reset PRAM on the 700 in between the tests? 24-bit addressing may have been re-enabled and that will impact scores.

Not sure about your RAM issue, but I recall a similar SSD symptom when using an OWC Mercury Legacy Pro, which [still] works fine in a TiBook. At the time I concluded it was a thermal issue since I would also experience lockup >30 minutes into a CCC clone. I switched to an IDE-CF adapter with a...

I realize this is no longer the question at hand, but for what its worth the 64MB Mobility Radeon 9000 in the TiBook will limit each display's frame buffer to 32MB, though the total can exceed this (3840 x 2160 can run at 32bit/Millions [~31.6MB] while the onboard panel is at 1280 x 854 /...

Great work @Realitystorm, this is excellent news. It also helps explain why I was consistently able to produce a working system by generating new .img files for the zuluscsi or restoring known working ones from modern macOS. Do you have a snapshot of this? I'd hope now that the variable has...

I took a risk and sprayed mine with PB B'laster a few years back. It made a significant difference, maybe 80% of the way back to new. It's still pretty smooth today, and hasn't ruined any of the paint/finish. If you try this, use plenty of paper towels to keep the spray off the screen and...

Not sure of the technical difference, but if I recall correctly: KTA-PBG3/128 is recognized as 64MB in 3400 models (80MB total); 128MB in Kanga. KTA-PB3400/128 is not recognized in Kanga (boots with only 32MB onboard); 128MB in 3400. Both variants use the same KTA-PB3400/128 PCB. Eventually...
