I think it's owed to an architectural improvement... the same drive/SEIV on a Q950 reached only about 8MB/s (closer to 9MB/s when overclocked to 40-45MHz or running a 100MHz DayStar 601.)

Not in front of me right now, but I was able to get ~18MB/sec on a Quadra 840AV with a 10kRPM 16-bit drive attached to an SEIV. I think the 8100/100 and 8100/110 will perform within ballpark. The 6100, 7100, and 8100/80 have an older version of the NuBus controller IIRC which may inhibit...

I haven't experimented much with this, but perhaps Classic environment would retain the advantage if nothing else?

The popular mitigation is to populate the IIci's bank A with 4 x 256k SIMMs, then set the disk cache (or use RAM-Muncher) to allocate the first 768k (or more if you plan to use video modes which use less than 640 x 480 x 8-bit = 307.2k) so that only the disk cache needs to share bandwidth with...

I do- do these closeups help?

Here are the two variants I've seen: The long/thin design is for the original G5, and also the Dual 1.8GHz variant of the subsequent June 2004 model. The other one fits the Dual 2.0/2.5GHz June 2004, the Late 2004, and Early 2005 models. The Apple service manual refers to this as "Soft...

I've been running an ATI FireGL X3 in my MDD G4 which @herd flashed with an Apple X850 XT ROM. It'll drive a 30" Cinema at 2560x1600 on one dual-link DVI port and the second port can run a 1920x1200 simultaneously. OSX drivers only, however. I'm not sure any Dual-link DVI card will have OS9...

Is this any help?

If you're using the LFH-60 cables with two DVI connectors + USB, then they're not actually DVI-DL. It's a discrepancy which can be a bit confusing, but those cables provide dual single-link DVI (two signals displayed side-by-side on the T221), whereas dual-link DVI natively interpolates each...

The three variants I've seen are 820-0550-A, 820-0615-A, and 820-0709-A (550c).

Having read your rationale for using this service I don't disagree outright- the site itself may be more than it appears, however. This request appeared immediately upon navigating to the page (Little Snitch, FWIW.) plugin-container is a Firefox component I rarely see activity from when not...

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.
