TekTronix DS1000G (NTSC version) Television Demodulator

The television demodulator can demodulate M/N standard television signals to baseband video and audio. In addition, the DS1001G provides the capability of recognizinga GCR signal and applying
correction to the baseband video output.

TheDS1001A/DS1001G covers the tuning range of 55.25 to 801.25MHz. The high performance of the conversion guarantees a measurement-quality signal after demodulation.

…from the author website:

Since the end of 2015, it became clear that the “good old” 1541 Ultimate-II was at the end of its life cycle. Xilinx, the manufacturer of the most important chip of the cartridge, had started to increase the prices of the chip. Also the memory chip started to be harder to get and at higher cost. When the news came that the company that made the black plastic cases for the 1541 Ultimate-II had lost the injection mold tool, it became evident that the 1541 Ultimate-II would be no more.

I have given it some thought. What would be the best way to continue with this project? When the feelings of being upset about the lost injection tool had subsided, I realized that this may be the perfect moment for an upgrade. This is when set backs change into opportunity.

Since then, a lot of work, and I really mean A LOT OF WORK has been done to create a successor: the “Ultimate-II+”.  Why not “III”, you may ask or think. Well, the foremost reason is the software. The install base of the “1541 Ultimate-II” is rather large (>3000 units), and I do not want to let my customers down that have just purchased a unit. This means that in case of new hardware, the same software should run on both the new board, as well as on the older board. So, the new board will offer similar functionality. You could see it just as an upgrade, not an entirely new product.

Although the “Ultimate-II+” is similar, there are also differences:

• No more MicroSD!  (… that needs to be pushed in with something sharp, could fall into the case, … etc)
• More USB ports (… one to compensate for the lost SD, and just one bonus: 3 in total)
• IEC connector moved (… further back to facilitate use on some C128 models)
• Integrated Ethernet (… no more need for an external USB2LAN adapter, and a smaller step to CS8900A compatibility)
• Dual Flash (… no more worry that a software bug or upgrade failure leads to a bricked device)
• Integrated Speaker (… who connects a speaker set to the audio jack for hearing drive sounds??)
• External power supply connector with auto-switch over circuit (… for stand alone mode, and to lower the demand on the power supply of the C64)
• Improved Audio (… audio codec, 24 bit/96 kHz*, for sampled sounds and SID emulation)
• Improved Tape connector (… no more custom board and able that snaps in on the bottom, but standard USB 3.0 cable)
• Improved power supply circuits (… for some reason they seemed to break down relatively often)
• Slightly bigger and faster FPGA, as to control the new features

DirMaster is a Windows-based GUI application designed to help Commodore enthusiasts explore and manage their disk image collections.

DirMaster supports common (and uncommon) emulator disk image formats (such as .d64, .d81, .d2m, etc), almost every native Commodore archival format (such as .arc, .sda, .lnx, etc), and many native graphic formats (such as koala, doodle, amica, etc).

DirMaster was designed to give users a perfect blend of familiar appearance (e.g. natural looking disk image contents using the PETSCII character set) and modern GUI functionality (e.g. drag and drop, opening multiple disk images at once). The first version of DirMaster was released in 2006.

v3.1.1 addresses a few bugs reported by users:

• Issue opening NAT partitions (.dhd)
• .dhd performance (no md5, .dhd BAM)
• Horizontal BAM display (.d71)
• Disk initialization when unzipping a 1-4! zipcode set when dragged from Explorer.

Sorry, this entry is only available in Italian.

Ikari has released a new firmware for the SD2Snes Flash Cartridge (Super Nintendo/Famicom). The upgrade instructions can be found here.

Here’s what’s new since preview 4:

• Configuration menu. All settings are now available through the menu. Changes take effect immediately after confirming a setting with the A button. It can use some polish but should work fine. Note that the Video Mode settings are only effective on SuperCIC modded consoles.
• SRM files (save files) are now stored in sd2snes/saves/<romname>.srm – existing save files will be moved upon save, there is no batch migration.

Game fixes:

• DMA de-initialization has been reintroduced and changed from $00 to $ff. This reflects a real SNES better and hopefully finally fixes sprite corruption with SGnG and SSF2, AND title screen glitches/crashes with Pocky&Rocky US.

MSU1 enhancements:

• MSU1 volume boost: In case MSU1 audio is too quiet you can now increase volume in several steps. Available via Configuration->Chip Options.
• Interpolation filter to reduce aliasing, resulting in cleaner sound.
• Fixed a bug where volume calculation introduced DC offset to the waveform output. This eliminates clicking or humming on volume changes/fades.
• Changed MSU1 audio playback rate to exactly 44100Hz to match bsnes/higan implementation. Sound that syncs on bsnes should now also sync properly on sd2snes.
• MSU1 resume feature implemented (Thanks to Michaël Larouche!)

Miscellaneous:

• Missing ROM files are automatically removed from the “Recent Games” list. (Thanks to borti4938!)
• Background text is now properly greyed out in the SPC player.
• Ultra16 awareness (mostly thanks to borti4938!):
  • Ultra16 serial number and autoboot setting is displayed in the System Information screen.
  • Exiting from the SPC player doesn’t crash the menu anymore on Ultra16 consoles.
  • Soft reset is prolonged a bit on Ultra16 consoles so you have the opportunity to release the controller buttons, not entering the Ultra16 menu by accident.
  • Auto region patching is disabled on Ultra16 consoles so it doesn’t interfere with the Ultra16’s own facilities.

Critical & Minor bugs:

• Firmware locked up when loading Zelda 3 after soft-reset. I am surprised that it actually worked so well with all other games.
• Auto Region Patch setting wasn’t saved properly.
• Satellaview custom time had a garbled default value (year 1035). The default has now been fixed. If you’d like to apply it you can delete your config.yml or just the “BSXTime” entry from it to load the new default.

• .d1m (read/write)
• Windows Explorer right click context menu, “Extract All Here”: extracts all files from the disk or archive file into the same directory.
• Add %H parameter to run in, to convert filename to $ hex characters.
• File properties adds file size in bytes and md5 hash.
• Ctrl x/c/v in a directory window will cut, copy, and paste files to and from the clipboard (mimics Windows Explorer behavior)
• Mouse over a sector in the BAM shows the file name and sector.
• Selecting a file will number the linked sectors in the BAM.
• Tweaks to batch output (html, seq, txt, csv), GEOS file handling, disk error handling (23/24/27/29), sfx/sda title handling, PETSCII tool.
• Bug fixes addressing d2m, d4m, d81, t64, g64, nib and other general functions.
