It's Basilisk II, they don't emulate any specific machine. Only DingusPPC and MAME emulate actual specific models with correct Gestalt IDs and correct innards.

English was common in Japanese software in the 80s because a full Japanese font would be gigantic and Japanese characters, and Japanese characters are more complex than Western ones. So in addition to the large storage for the font, you need a higher resolution for them to be legible (or the...

From what I can tell, there were multiple versions of these cards. The ROM version for the card I emulate in MAME is marked "TPD FPD-ASIC v4.1" and the ROMs are at locations U6 and U7. I would expect a card that works with both monitors to have two crystals: one 51 MHz (FPD) and one 99 MHz...

Low brightness I'd suspect the replacement tubes want a different voltage range on the main video grid, although if you can adjust it to get retrace lines it might be that the second anode voltage is too low.

The SuperMario code I pointed to indicates that a real 6100 returns 0x3010 from the hardware, but then it checks if it can freely set and read back bits 2 and 3 of the DMA control register for the SCSI bus. If it can't it's "first silicon PDM" and it doesn't change the ID. Otherwise, it checks...

Correct. https://github.com/elliotnunn/supermario/blob/9dd3c4bef84df2ea30f5ec2c5e97b043e8267b3f/base/SuperMarioProj.1994-02-09/OS/Universal.a#L2780 indicates that PDM does have to read the ID register a byte at a time, and the code there is fascinating in terms of how it differentiates the models.

EVT is Engineering Verification Test, which is pre-final hardware. For whatever reason some EVT logic boards had different IDs and even boxflags/gestalt IDs from what shipped.

The second half of that DuoDock II ROM likely has additional useful data, so it'd be nice to get a complete dump. Regarding the original point of this thread, ESC+L+F+W works great in MAME. Edit to add: ESC+S+E+T works for me on the Quadra 900 but not the 700.

The 9FEB69B3 (77D/20F2) ROM should be the original PDMs and 9B7A3AAD (77D/23F1) in the speed bumps, I think. (It's possible later-production non-speed-bump machines also came with the newer ROM though). The 9FEB69B3 ROM shows these 3 non-68K machines in UniRom. [info 15010, vers 1] Box...

GGLabs' page for the card says they fixed the card to ID 7 and changed the ROM and GS/OS driver to reflect that. That's likely why the stock Apple driver won't load.

Heathrow and Paddington both have PC-compatible MFM controllers built-in. O'Hare had SWIM III only, and KeyLargo has no floppy support at all. The documentation suggests that PowerBooks needed MFM controller support so you can plug PC-compatible drives into the media bay, but I don't think...

There was supposed to be an updated IIgs introduced in the fall of 1991 on a satellite broadcast to user groups along with the LC IIe Card, Mac System 7, an Apple II Ethernet card, and IIgs System 6. It would've had a built-in SuperDrive and SCSI HDD, a SWIM instead of the IWM, DMA SCSI...

The original LC PDS does have all 32 data bus lines. It's missing like 6 of the 32 address bus lines in keeping with the LC's general addressing weirdness. LC III PDS adds back those missing lines and more slot interrupt signals, so LC III PDS probably could be adapted to run at least some...

It's not uncommon for declroms to have MacsBug symbols. Even the ROM on the big A/ROSE-based Ethernet card has them (for the on-card 68000 routines, which is nice).

As far as I know it's original. Some of them are just in blue for reasons I don't understand.
