I received my 2 cables in the mail: Here's how the continuity works out between the 2 ends of that 2 cable chain: Again, doesn't look perfect! I went ahead and tried it: Mac side: There's not much to do but to launch the game, select "Mac to PC" in the Communications menu PC side: this...

thanks for the suggestion, I wasn't aware of it, and it should be easier to pick up with my son as well (aka not have to read 40 pages in the manual) thanks for that. I think I'll do a 2-prong approach. Irreversibly modify the badly wired cable I have according to your notes, but also figure...

Last year, I bought the boxed game of Falcon F-16. In the supplemental documentation added with v2.0, we can see this paragraph: Goal: serial link multiplayer game between a vintage Mac and vintage PC using a null-modem link between the two! Mac side: Falcon F-16 v2.0 (the update that...

"Screen Shaver" Concept and art by Japhy Riddle C programming from me, Mu0n aka 1bitfeverdreams aka Michael Juneau Very elegant concept where a razor will "shave" on a new classic b&w pattern on screen until it's filled, then it starts over again. Once I learned and saw Japhy's mock up...

Thank you! If you think it can help the readme section of the project's GitHub page, I'd be happy to have my video linked from it as a sort of complementary guide to using and building the unit. I tried checking my Super Studio manual, as well as the still running madcapps website that hosts...

I made a 23 minute video on building it and messing with it (mostly for Studio Session)

Attempts made Mac Plus: SoundEdit 1.0 crashes if I open it from my bluescsi system 6.0.8, but runs if I let it boot from these diskettes (finder 4.2), then you're left with 60kb free on disk unless I whip out a FloppyEMU or external disk drive SoundEdit 2.0.5 runs under System 6.0.8 no...

I'm happy to sell: 1x bare main PCB 1x front case plate PCB 1x back case plate PCB 1x pre-programmed pic12F1501 chip, which you'd then be able to remove from the Bom list you'd buy yourself. Keep in mind I'm in Canada and sending even a small box to the US is now salty.

Let's do a napkin economic analysis about this particular project. First of all, despite it being well known in the late 80's, it concerns mostly 68000 macs since other solutions started appearing around the time of the powerbooks, making it relatively niche. While the PCBs are cheap (around $6...

I tried my hand at building my own unit thanks to the great documentation from the github page. Happy to report: success.

thanks all, it seems to work taking 0 chances with: -using a MaxApplZone() at the start -using MoreMasters() for good measure (who knows how some .midi files go up in size and data content) -NewPtr and DisposePtr for those arrays in case a 2nd, 3rd, etc file is loaded up (so I'm currently...

MaxApplZone(); MoreMasters(); is a promising avenue being tested atm. edit - and using NewPtr for those dynamically allocated arrays instead of malloc and using HLock HUnlock on theBigList....

ok, the same example above, after running back in forth into my main project, rebooting my emulator, etc. no. longer. works. I bet it's something really easy I'm missing but I'm properly stumped. this should output 0,1,2,3 in the first 4 trackno debugging values on the right since I'm at...

so maybe the solution is to use a handle so I can avoid my structs pointers to get trampled over? seems to work here:

I've been working on programatically open up a .mid file, parse it to find the minimal MIDI command bytes out of it and set up a data structure that makes it easy to play it back on a System 7 Mac SE/30. All the more esoteric parts of the project have been more or less solved already, but this...

YES, it finally works. Thanks for the refresher tips on bytes and on how to address pointer offsets more efficiently. Thanks for your patience and offering great guidance and some good ol' vintage docs. As soon as I saw the scope behave well with this under 31,250, I disconnected my breadboard...

Can anyone verify if I'm doing what I think I'm doing? int *addr = (int *) 0x0001DA; *addr = 11; asm { MOVE.B (SP),(SP) } *addr = 0x28; this freezes my program but I still can move my mouse cursor around. When I click, even that freezes as well.

Good idea. It gets my bytes correctly at 38,400 set in both the mac SCC through SerReset and on the scope, using these 2 lines: const int kConfigParam = 1+data8+noParity+stop10; gOSErr = SerReset(gOutputRefNum, kConfigParam); I have no easy way to probe these lines. My small MIDI...

Getting MIDI across to my sound modules I have achieved, no problem, for years. However, only through commercially developped software that I open and execute as an end-user (Cubase, Space Quest III, Master Tracks Pro 4, etc). The goal is to recreate what they did through my own C routines. If...
