As Steve Jobs would tell us, the correct solution isn't always the one you think you need. Stringing wires is expensive and causes a permanent major maintenance hassle. A large majority of the rural US has LTE or 5G coverage, both of which blow the doors off dial-up, and the parts that don't...

That must've been a very early setup originally. You don't see many IIcs with the "proper" IIc styled external drive, and you definitely don't see many with a printer that's not an ImageWriter II.

For what it's worth, there were PC MOD players at the time that worked on the internal speaker (generating PWM on the fly, similar to speech on the 8-bit Apple II). I don't recall how fast of a CPU that needed - I saw it running on a 386/16 I believe.

That's known, there's even code in GitHub demonstrating the interaction.

Incidentally, I said before there was a combo PC/Megadrive where the halves can't interact. It turns out there's also the Sega TeraDrive, which is a 286 PC/AT clone with a Megadrive built-in, and both halves can access each other. The 68000 can talk to the VGA card and SoundBlaster and...

Even some shipping hardware synths have issues with active sense and other real time ($Fx) messages since they can legally appear at any time. Some lose track of running status for note on/off when a real time message comes in, for instance.

I emulate 3 of the Lapis cards in MAME now, the NuBus ProColorServer 8 and ProColorServer 8*16, as well as the SE/30 ProColorServer 8. The twist with them is that the the ROM contains a complete Xilinx bitstream for each color depth and resolution, which takes a *lot* of space and is probably...

Is OP aware of Shoebill, which does exactly what they want? A/UX currently falls over hard on MAME. I haven't spent much time trying to discover why because Shoebill exists. MAME does run many other 680x0 UNIX versions, including Apollo Domain/OS, HP/UX, Sony NeWS OS, and SGI IRIX (we also...

I got to check out these ROMs. The FPD and TPD hardware is completely identical except for the resolution (640x870 for FPD, 1152x864 for TPD), and also identical to the later ASIC-based version of the cards. ROMs from the later 1991 632-0022-A1 ASIC-based board will likely work fine on these...

The ultimate reference is the ProTracker 68000 source, because there's a fair amount of corner-case behavior that certain MODs rely on. But that's only correct for newer MODs that were made on ProTracker rather than SoundTracker. There's a famous (and very good) MOD called "Klisje Paa Klisje"...

The SuperMario code in general has some obvious gaps. I'm guessing it was forked from the previous generation before a lot of 1993/1994 machines were added. To give one example, the DFAC 2 audio I/O chip first seen in the LC520 only gets a mention as a feature flag bit in the Universal tables...

I don't know of anyone that's done that, and I'm not sure how SRAM would play along with the way Woz hid the DRAM refresh cycles, but it doesn't mean it's not possible.

ADB on the Duos is a little weird. On the 280c the keyboard is a bare matrix keyboard like the Apple IIe and the trackball is a quadrature device, like an M0100 mouse. The Power Manager microcontroller emulates ADB devices for both of them, but it also has a pin to communicate with a standard...

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...
