That's odd. If the trackball appears in ADB Parser then ADB communications is working, as far as I'm aware. The 180 isn't like the 150 and the Duos where the power manager can spoof ADB devices.

Current MAME at least does fetch the samples and disk PWM data per-scanline during the live raster for the 128/512/Plus/SE, and I have some stuff queued up to make the output filtering more accurate to Burrell's. Having done it when I was young and stupid, half of writing a MOD player is...

Thanks!

Yes, you can turn slots 5 and 6 to Your Card and the on-board IWM basically doesn't exist at that point.

Incidentally, there were a few combo MS-DOS PC + MegaDrive/Genesis machines. None of them actually had any sharing between the two sides though.

It is possible to crash many commercial Genesis games, particularly if you modify a controller to allow you to press contradictory directions at the same time (up+down or left+right). A very well-used controller will eventually wear down to where you can do that as well.

Just to verify, your own ROM dump from your card has an SHA1 of 451c85c46b92e6ad2ad930f055ccf0fe3049936d? If that's the case, it sounds like the card is working perfectly fine, but you are missing the Apple SCSI drivers. MAME has register-level emulation of the Apple Rev. C SCSI Card (which is...

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...
