A few things: Here's a link to firmware for 3114 cards for OSX only: https://www.siig.com/download/search?keyword=SC-SA4M12&f=true .. the flasher works for 10.1 only, I think, but the firmware can be extracted for other flashing methods. The FirmTek 4-port firmware (ROMFILE.7174) doesn't work...

The accelerator is a General Computer HyperCharger 020. For the ci and Quadra, I see as much variability in timings between individual runs than between Pi and Pi20. Also, runtimes vary with different OS versions. For the SE, 7.1 020 accelerator @16MHz: Pi Pi20 100 0.12 0.12 1000 4.00...

These times for Pi. Pi20 is only very slightly faster. SE, 7.1 020 accelerator @16MHz: 100 0.12 1000 4.05 3000 30.57 IIci, 7.1, 030 + cache @25Mhz: 100 0.08 1000 2.53 3000 19.5 Q650, 7.6, 040 @33MHz: 100 0.03 1000 0.93 3000 7.33

Yup, the G3 is a temperamental beast .. part of its endearment. You do need to run Tiger. it installs easily with the XPostFacto dance, and I've found 10.4.11 is nicely stable.

Here's the FWB test result on my Beige G3 DT. The drive is an OWC 3D SSD: In comparison, an HYPERDISK SSD on the IDE bus gives:

If you're not bothered about parity, I've used OWC a number of times: https://eshop.macsales.com/item/OWC/30PS16MB/

Don't get me started about this logic :cool:... Here's a couple of my experiences that: On a Iicx with similar logic, the machine would start using the power switch but not do a soft-startup. This was the result of a re-capping boo-boo with a couple (C15/C16) being reversed. On a IIci which I...

The information out there is indeed fragmented, out of date, and not entirely reliable. There also must be checks in the Classic Mac driver code and probably in the OFW FCODE too. After patching the NDRV section of the rom for OSX to accept my different EEPROM part, OS9 failed to recognize the...

I could have used your write-up a few month ago … I too have recently been down this path. In my case, it was for a Beige G3 DT. There’s several of threads available online as guides -- in particular: https://68kmla.org/bb/index.php?threads/sil3112-flashing-sata.21640/. But I’ve also explored...

I have a SCSI2SD. With HFS you must stick to a SCSI LUN of 2GB or smaller, so that's what I used. I used HDsetup (or perhaps LIDO) to create a small HFS boot partition for a minimal MacOS 7 install together with the NetBSD install/boot kit, plus a UNIX swap partition and a UNIX root partition...

I installed NetBSD9.1 over a year ago on a Iicx (and I presume 9.2 would be similar). Use an ethernet card and do a network install. I was amazed how easily a current OS installed on a 30-year old machine. BUT: it's very slow to use. I subsequently re-installed NetBSD3.1 which is less resource...
