Ah, thanks for clearing up the PAL usage. I just tried it, and the Sync-inator seems to be working fine in Apple IIgs PAL mode. The horizontal refresh rate is unchanged at 15.7 kHz and only the vertical rate changes to 50 Hz. If I had the right kind of Samsung SyncMaster or other LCD with 15 kHz...
I think I've got the Sync-inator working on the Apple IIgs, and the hsync/vsync output looks right on the logic analyzer, but none of my six LCD monitors are able to handle the 15.7 kHz horizontal refresh rate. If I had an appropriate monitor, I think it would work.
For the IIgs, this will draw...
According to the standards for composite video, which Apple may not have followed exactly, NTSC should be 15.734 kHz horizontal and PAL should be 15.625 kHz. Reality may be different, as I'm measuring 15.70 kHz here rather than 15.734 kHz. So maybe Apple chose a single horizontal rate to split...
Could anybody help provide some timing data for Apple IIgs PAL video, from the composite sync signal on pin 3 of the DB-15 monitor connector? This is probably the same as the timing from the composite video jack, but just in case it differs, I'm looking at the DB-15 monitor connector. I'm trying...
Or another possibility, use Disk Jockey to extract the HFS partition, mount that (but don't try to boot from it) in Basilisk II, and replace the System Folder. You might also need to run Disk First Aid on it.
Try using Disk Jockey to open the image. If it's just the driver partition that's messed up, then you should be able to extract the HFS partition and reuse it.
Pin 8 has no connection on the standard Mac video port, but pin 7 is sense bit 1. Depending on how you set the DIP switches, that could connect -5 volts to sense bits 0 and 2 (pins 4 and 10) or to ground. Maybe it's possible to work on the IIgs, but at the risk of a miconfigured DIP swtich...
The final pieces are coming together now, and I've got everything mostly working on the Toby card and the SuperMac ColorCard SE/30, as well as the other more normal cards and Mac models.
What do you do with a microcontroller-based VGA adapter when you have one free pin remaining? Turn it into a...
Yes I completely agree. But if you're purposely trying to design a CRT look-alike, as this Kickstarter is, then I think you need a solution for a faux curved surface. IMHO it just looks strange with a flat surface, but maybe I'm too picky. :)
I wonder if you could add a curved glass front over the flat LCD. It would probably be too expensive to justify just for nostalgia's sake, and it might distort the image too.
Was this feature just added? I'm running Disk Jockey 2.5.2.2 and I don't see any way to extract files. Dragging and dropping an item from the file list doesn't do anything. The whole Disk-o-Matic section of functionality is also missing in the Windows version, so it's not a solution I could...
It does, and wow! This is really great! It's a standard Mac app with a nice GUI and I can drag files in and out of the disk image.
Unfortunately the HFS support seems to have some bugs. It was able to open many smaller disk images I tried, but anything non-trivial resulted in an "invalid file...
I had some more time today for finishing up the VGA Syncinator. All the other sync pass-through modes are working now, which wasn't necessarily a given. The "pass-through" isn't a physical switch, but a microcontroller function using built-in programmable logic cells to asynchronously copy...
I'm not going to say you're wrong, but why would you rather have it that way? I can see your point about having a standard power connector - Zulu SCSI has this as a $3.50 option when ordering. But as for the rest, from my viewpoint there are only drawbacks to whole-card emulation and no...
Disk Jockey is nice, but I think it's focused on a different purpose. As far as I'm aware it's not a tool designed to look inside a disk image and manipulate, add, or remove individual files. I've used Disk Jockey to add and remove whole volumes from a multi-partition device image. CiderPress 2...
In another thread, I was lamenting the lack of good cross-platform tools for working with HFS Macintosh disk images. Thanks to @NJRoadfan for pointing me to CiderPress 2, which is currently in 'alpha' development but is already very capable. The original CiderPress only handled Apple II disk...
You're trying to do SCSI2SD-style emulation where the whole SD card is the device, or file-based emulation where a file is the device? Unless you have a specific use case in mind that requires SCSI2SD-style emulation, I think file-based emulation is a whole lot easier.
1. Format the SD card as...
CiderPress II tooks very promising! I didn't realize it had added MFS and HFS support.
The proposed feature set seems very ambitious, but if he gets all of that working it'll be awesome. It's targeting eight different filesystems (not just HFS), with eight different disk image formats (not just...
