After many years i have found in my historical backups the developer kit for Gameboy that i have used to make Demo & Trainer for Gameboy (color) for Nightfall and then Nightfall^Eurasia.

The last time that i have used this compiler was the late 90′s.

I just had to replace the old no$gbm the GB emulator that didn’t run at 64bit and i don’t like the new version of this emulator with the Visualboy Advance and everything started working perfectly, including the compiler.

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

Issues reported by users that were resolved in v3.1.5:

• BAM can display a file chain for an offset file depending on Show Deleted Files toggle [0200] (M. Huth)
• allow VIC-20 BASIC files to be viewed [0201] (S. Houdek)

Issues resolved due to user interest in v3.1.5:

DirMaster has supported 40 track disks since v3 in a limited read-only manner. Some users (most recently, hedning/G*P) expressed interest in better support for 40 track .d64; in response, v3.1.5 resolves these issues, with more features likely in a future version:

• PrologicDOS diskname and id are read from the wrong location [0176]
• improve detection of PrologicDOS, DolphinDOS and SpeedDOS [0208]
• blocks free doesn’t account for tracks 36-40 when an extended track DOS format is detected [0209]
• enable writing files to tracks 36-40 on extended DOS format d64 [0210]
• extending a disk from 35 to 40 tracks should initialize the extra BAM for a default extended DOS (default = DolphinDOS) [0211]

Thanks to all who made an effort to submit bug reports and feedback. If you sent a bug report and don’t see it addressed here, don’t worry, it’s in the queue.

Other issues resolved in v3.1.5:

• Can’t set a sector error to 29 [0202]
• a .cvt file that contained a .cvt file would unarchive back to the containing .cvt [0203]

There are not many interesting things to recover, for example the 256k x 4 ZIP Ram are absolutely useless.

So what i have recovered that could helpful (never) is the Motorola 68030RC20B CPU, the 68882RC25 math coprocessor and 3 x Clock Oscillator.

This monitor is the PAL predecessor to the Commodore 1802. It appears to be a contemporary of the CM-141 and the brown-casing 1802. They both have dual inputs (Composite video/audio, and chroma/luma/audio) with a switch in front to select between them.

The Monitor although in excellent condition don’t work correctly, the image displayed was in black and white.

The problem was the oxidation of a little trimmer (see photo / orange trimmer) and it was enough to turn it a bit and put it back in its original position.

Other small defects fixed:

• Bad geometry – Calibration of the Deflection yoke.
• Out of Focus – Calibration Trimmer Focus on Flyback.
• V-HOLD fine adjustment on the Monitor PCB.
• Glued a piece of plastic broken at the base of the monitor.

The ZX Diag Cart by ByteDelight will visually show all kinds of details of your ZX Spectrum, which is both looking cool and useful at the same time!

It will make diagnosing defects a lot easier:

• Quickly check if voltages are present.
• If there is a dataline ‘stuck’
• If the M1 line is working…

The ZX Diag Cart automatically detects to which ZX Spectrum model it is connected, so it can control the ROM signals on ZX Spectrum 16/48K, 128K+, +2, +2A or +3, and many clones.

ZX Diag Cart Test and Sinclair ZX Spectrum 48k Issue 2 Repair:

I wanted to try this nice but also useful interface with my historical Sinclair ZX Spectrum 48k, not even doing it on purpose after several years of total inactivity the ZX Spectrum no longer worked.

The defect can i see is a total malfunction of the Basic interpreter with random errors and using the ZX Diag Cart i have see an error on all 16k RAM banks.

The voltage monitoring LEDs on the ZX Diag Cart show me that the -5v and the +12v are missing, consequently it was not a RAM problem but instead the transistor ZTX 650 (TR4)

Replaced the transistor it all work perfectly and passed all disgnostic test of the Diag Cart.

Two new mounting system for the optional RGB controllable 24 LED light strip for inside the 64c case.

Angled mount version:

This mounting design attaches to the top of the metal shield surrounding the cartridge port. Its angle allows the light of the RGB LEDs to exit through the ventilation slots of the C64c case.

Keyboard mount version:

This mounting design attaches to the back lip of the keyboard through existing factory holes using black oxide screws and heatsets. It is a two piece system with a left and right component.

Like the previous version, the RGB LED light comes out through the ventilation slots of the C64c case.

Note:

This version is not fully compatible with my keyboard mount that i’m using on the left side. I had to remove with the hacksaw a piece of plastic to solve the problem. (see photo)

Not fully satisfied of the Pi2SCART purchased a couple of years ago i also wanted to try the RGB-Pi (Scart & Jamma) interface and i must say that in combination with the RGB-Pi OS software it does his dirty work.

What i liked about the RGB-Pi OS software is the extreme facility to adjust the size and position of the screen and all games (vertical or horizontal) adapt perfectly.

The Software also includes other enhancements that you may like or dislike.

Monitor used: TAXAN Vision EX Monitor.

After many years i have decided to made some improvements to my Sinclair ZX Spectrum 48k Issue 2.

Below what has been done:

• Replaced the obsolete 7805 voltage regulator with a modern and performant one that heats up much less; the TRACO Power 2450 (DC / DC Converter)
• Replaced the ULA Ferranti with a fully compatible FPGA solution (vLA82 designed and created by Charlie Ingley). Again it does not heat anything.
• Replacement of all electrolytic capacitors.
• Rework of an old Composite MOD with a more performing one.
• Replaced the Membrane and the bioadhesive to fix the keyboard with hard keys.
