CBM prg Studio Version 3.2.0 is released. There are a lot of new features in this version. I’d really appreciate it if you report any bugs you find or have any suggestions/comments.

CBM prg Studio allows you to type a BASIC or Machine Code program in using a nice Windows environment and convert it to a ‘.prg’ file which you can run on an emulator, or even a real C64 / VIC20 or PET if you’re feeling brave and have the right kit.

CBM prg Studio is the result of merging C64PrgGen and VIC20PrgGen. Adding new features and fixing bugs in two apps which were 95% similar was a bit of a nightmare so merging them made sense.

It was also a good opportunity for a face lift and to add some new features, such as:

• Programs are project based, meaning all related source files, sprite files etc. are kept in one place and multiple source files can be linked more easily.
• Tabbed MDI.
• Syntax highlighting.

What CBM prg Studio isn’t is a front-end for tok64, cbmcnvrt, bastext or any other tokeniser / detokeniser / assembler. It’s all been written completely from scratch.

New features:

• PTEXT and NULL directives.
• NULL added to GenerateTo directive.
• Colour printing.
• Source overview.

Bug Fixed:

• Assembler:
  • Reformatting code.
  • Some arithmetic problems with variables.

• Basic:
  • Some screen code fixes.
  • Renumbering TRAP keyword (BASIC 3.5 & 7)
  • Mixing upper/lower case in DATA statements.
  • Wrong load address for some C128 BASIC projects.

• General:
  • Better support for Turkish language.
  • Wrong toolbar shown after start-up page.
  • Case sensitive auto-complete
  • Problems with the build events.

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

Full Changelog:

A minor update, mainly in the name of stability. This hopefully eliminates glitches unrelated to the in-game buttons on some consoles, e.g. Seiken Densetsu 3 rebooting intermittently or graphical glitches in DKC 2+3, that had been introduced with v0.1.7 preview 1.

• Reintroduce more aggressive filtering for control and address lines from the SNES, previously removed after v0.1.6
• Unify and centralize signal edge detection for all sub-units (e.g. S-RTC, MSU1, BSX, DSP etc.) instead of each unit having its own (slightly different) edge detection.
• In-game controller scan has become slightly more time effective under certain circumstances (Auto Joypad Read enabled but no NMIs).
• In-game hooks are now disabled for 10 seconds after loading or resetting a game to help certain games get past their boot screens. This will be configurable in the final.
• Reconfigure the FPGA only when necessary on warm reset, speeding up “reset to sd2snes menu” by a couple hundred milliseconds.
• Fix an MMIO access priority bug for DSPx.
• Fix BS-X ROM detection for games with 2 startups left.
• Fix directory browsing being broken after setting the clock.

The Commodore 4040 is the replacement for the previous models 2040 (USA) and 3040 (Europe). It’s a dual drive 5¼” floppy disk subsystem for Commodore International computers. It uses a wide case form, and uses the IEEE-488 interface common to Commodore PET/CBM computers.

These drive models use a similar single density, single side floppy data storage format to that used by the Commodore 1541 drive, but with a slightly different data marker indicating which model originally formatted the disk. The low-level disk format was similar enough to allow reading between models, but different enough that one series of drive models could not reliably write to disks formatted with one of the other model series.

I have adapted a power supply Cisco (P/N 34-0874-01) to be used with the Home Computer Amstrad CPC 6128/664 that use two voltages +5v and +12v (pinout). If you want to use this computer without the original monitor the only way is use a external power supply.

The photo speak for themselves, the modification is very simple. The only thing that i want to say, maybe not everyone knows it, the Cisco power supplies uses the STANDBY remotely, you need to connect together the ROF line with the one of two RTN (GND).

I have also added a third cable in case you want to use an external Floppy Drive.

The HxC Floppy Drive Emulator is a software and hardware system created by jfdn aka Jeff.

The aim of this project is to replace the floppy disk drive by an electronic device emulating the floppy disk drive (list of supported Computer/Hardware).

There are two differents emulators:

• A USB version which allows to connect the floppy disk drive interface of the computer to a PC via a USB cable.
• A SDCARD version which allows to emulate floppy disks which images are stored in a SDCARD.

Release notes for the HxCFloppyEmulator software v2.0.26.0:

• New Loader : PC Magazine (FLP) file format support added.
• GUI – Track viewer window : Track editing functionality added, internal sanity check added.
• libhxcfe : Casio FZF loader -> non sector-aligned file image size issue corrected.
• libhxcfe : Generic flux stream analyzer enhanced – Track encoding & RPM correctly reported.
• Batch converter : Now use the folder name for the output filename while converting KF stream files (raw).
• FAT12 Disk Browser:  PC98 FAT disk support enhanced, free space reporting corrected.
• Raw Loader – Predefined raw formats added (XML) :
  • Logical Interchange Format (LIF) 3″1/2 264KB (single side).
  • Logical Interchange Format (LIF) 3″1/2 616KB (double side).
  • Logical Interchange Format (LIF) 3″1/2 1232KB (HD).

The Tandy Radio Shack TRS-80 DT-1 is a video terminal. It is ideally suited for communications with the TRS-80 Model 16 Multi-User Office System or with other host computers. With a low-cost Tandy acoustic coupler it can also access time-sharing information networks.

Gallery:

12►

State-of-the-Art Design:

Unlike many terminals, you can easily set up and change the configuration on your DT-1 from the keyboard. A revolutionary non-volatile memory that retains your terminal configuration even with power off and without battery backup!

Multiple Emulation Modes:

The DT-1 is completely code compatible with four standard terminal protocols.

• Televideo 910
• Lear Siegler ADM-5
• ADDS 25
• Hazeltine 1410

The 30.5 cm diagonal CRT displays 24 lines of 80 upper and lower case characters per line. Special single-character symbols are used to display control characters.

Dual-Speed Repeat:

Any character can be repeated by merely holding down the desired key. After several characters are repeated, the DT-1 will automatically repeat the characters at a faster rate.

Two Printer Ports:

The TRS-80 DT-1 can be equipped for hardcopy output by connecting a printer to the built-in RS-232C serial interface or parallel interface.

Special Features:

A local monitor mode lets you enable printer ports and position the cursor using local control and escape modes. The carrige return key can be programmed with or without a line feed. Control key termination codes are also user programmable. An electronic bell is standard.

TRS-80 DT-1 Highlights:

• Data Transfer: 75,110,150,300,600,1200,2400,4800,9600,19200
• Cursor: Four keyboard-selectable types: Steady, Blinking Block, Steady or Blinking Underline.
• Video Attributes: Normal, reverse, Invisible, Blink, Underline and Half-Intensity Video.

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

Full Changelog:

It addresses some issues reported with v0.1.7 preview (and some others).

• Satellaview works again. BSX alters the original interrupt vectors at run time. The original interrupt vectors are now saved per hook call, not only once when loading the ROM.
• In game buttons now work with MSU1, too.
• Automatic hook method choosing: NMI is default but switched to IRQ when no NMIs are triggered. If both occur, NMI has priority. This should enable the in-game buttons for games that previously did nothing.
• The hook routine saves some CPU time when auto joypad read is enabled by the game – it will just reuse the result instead of doing its own controller scanning. Also the controller is now only scanned every 8 frames. This helps alleviate some glitches, e.g. Secret of Mana now starts up correctly. There are still some glitches left which can’t be eliminated fully.
• Auto region patching works again without having to delete the sd2snes.cfg.
• BSX now emulates Type 1 memory packs instead of Type 2. Apparently the BSX BIOS is buggy with Type 2 packs when they contain HiROM games that are supposed to be run from PSRAM. So, at least Bomberman works now, and probably others too.
• Fixed BSX PSRAM shadowing for HiROM.
• Files and directories with “hidden” or “system” attributes are now actually hidden from the file browser.
