These CPU MOS 6502 received from China are very interesting.

The production date is really very curious; 43th week of the year 1935. They certainly recycled non-MOS CPUs and sanding the top layer of the chip and have printed a new label.

7 CPU of 10 are working.

This is the last batch of iNTY ZOE RGB v2.0. I just want to inform for those interested that i’m starting the assembling.

I could not resist the temptation to try also this “we hope it will be the last one!” FPGA implementation of the SID (Sound Interface Device) MOS 6581 / 8580, i’m talking about the fpgaSID by andi6510.

Probably this is the best implementation using an FPGA of the sound chip of the Commodore 64. If we make a quick comparison with the implementation made by Gideon for the Ultimate-64, both are the best ever.

It remains however understood that the audiophiles and purist of the sound generated of a original SID will never accept any implementation of the SID via FPGA.

andi6510 also wrote a software for the Commodore 64 (ConfiGuru) to configure the various fpgaSID options and for upgrade the firmware.

Below some information taken from the fpgaSID site.

Accurate replication of the original SID MOS6581 and MOS8580:

• Exact reproduction of the digital sound generation part
• Spice simulation of the analog filters
• Advanced models for all 6581 non-linearities

Many extra features on top of the original SID:

• FPGASID includes two fully functional SIDs for 6-voice stereo sound
• Perfect audio quality – much better than the original SID!
• Pseudo stereo mode mixes traditional tunes or game sounds to stereo
• Digitize the analog input to 8-bit samples (in your own software)
• Sample playback of 8-bit samples (in your own software)
• Nice light organ effect visible when mounted in transparent case
• Paddles readout even more accurate than the original SID

High compatibility:

• Works in any C64/SX64 or C128
• Works with any software written for standard single SID computers
• Works with large existing software base for dual SID stereo tunes
• Paddle and 1351 Mouse support
• Analog input EXTIN fully supported

Easy configuration with the software tool ConfiGuru:

• Individual configuration of every SID
• Easy- and Expert configuration modes
• Save up to two configuration sets permanently in flash memory
• Easy update to new firmware directly on your C64
• Flexible address allocation of the second SID
• Diagnostic function to troubleshoot hardware problems

Easy installation:

• Installation done in 20 minutes
• No soldering required for all main features (except external configuration switch, when needed)
• Much smaller than traditional stereo boards thus avoiding installation trouble

New update : HxC Floppy Emulator file selector version 1.89.

Amiga -> Better multitasking/Workbench compatibility/support:

• Don’t “overtake”/hand-initialize the screen anymore : Let the system initialize the bitplane and just use it.
• Don’t reboot anymore the system but just exit the file selector if we are not track-loaded.
• Don’t lockup the system anymore in case of error if we are not track-loaded.

With these modifications the file selector is now more “Workbench-friendly”.

Amiga Workbench tips and tricks :

• Press Left-Amiga+N keys to switch to the Workbench.
• Press Left-Amiga+M keys to switch back to the HxC File selector.

Firmware upgrades for THEC64 Mini provide new features and/or correct any technical issues.

We always recommend that you use the latest version of the firmware.

Version 1.2.0 – Changes:

• Adds a complete new game for free to the GAMES CAROUSEL! Galencia for the Mini is licensed from Jay Aldred and is the winner of the Reset64 Magazine 2017 Commodore 64 Game of the Year Award
• Introduces the Virtual Joystick. You can now select all options on THEC64 Mini and even play games just using a USB keyboard. See Virtual Joystick for further information
• Improves the File Loader to allow multiple programs to be configured at once. See Setting a Default Configuration for Multiple Programs for further information
• Remembers the mute state of the CAROUSEL music between reboots
• Improves the general performance of THEC64 Mini screens and menus

Note:

Galencia is the winner of the Reset64 Magazine 2017 Commodore 64 Game of the Year Award. It is a colourful, highly polished, Galaga inspired single-screen shoot-em-up.

Jay has worked really hard to produce a special version of Galencia just for THEC64 Mini and its 720p display, and it makes maximum use of the upper and lower borders for graphics, right up to the edge of the screen! Be aware however, that some HD TVs might crop some of these border graphics when displaying the 720p image. This is not a fault with Galencia or the Mini and we recommend that you refer to your TV settings.

Please be aware there is currently a 256 item limit (files and/or folders) to assist improved USB memory stick performance.

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

Changelog:

• SA-1 support by RedGuy! Big thanks to RedGuy again :) This was a really tight fit for the FPGA so there’s a little catch – MSU1 is not available for SA-1 games.
• Also from RedGuy comes partial SRAM detection for some known games (SuperFX & SA-1). This calculates a ROM CRC and chooses to monitor only specific regions in cartridge RAM for changes. This enables automatic saving without having to resort to periodic saving, reducing wear on the SD card.
• SNES CPU <-> PPU clock phase alignment. This is a long standing issue on a sub-CPU-cycle base inside the SNES. HDMA to certain registers can cause flickering sprite slabs to appear when CPU and PPU are out of phase after a cart-side reset (which does not reset the PPUs). This fixes the notorious flickering of characters with the giant frog attack in Chrono Trigger, sprites in Kirby Super Star, characters behind the text box in Star Ocean, and probably more. See https://github.com/RedGuyyyy/sd2snes/issues/6 for technical details.
• Added an option to always go back to menu on reset, regardless of whether it’s a short or long reset.
• LED brightness setting (16 levels)
• Added an option to choose whether you want to start a game with or without cheats enabled (of those that are marked as enabled in the YAML file). You can enable / disable them later using the L+R+Start+A / L+R+Start+B button combinations if you have in-game buttons enabled.
• Disable Satellaview emulation when a real Satellaview base unit is detected to avoid bus fighting and facilitate Satellaview development.
• System Information now shows the currently effective video mode (50 or 60 Hz).
• Fixes:
  • Control signal edges are detected a bit earlier, improving stability on some consoles (Github Issues)
  • Fix timing of auto region patching. This should solve cross-issues with Super Scope games because they rely on the same register that is also used to read the console region.
  • Fix brightness patching / limiting for games that use HDMA to alter the brightness register. (e.g. Star Fox)
  • Fix an occasional imaginary access cycle carried out by the FPGA after reconfiguration. This fixes lockups when loading games with dedicated FPGA files, i.e. SuperFX, SA-1, OBC-1.
  • Fix SuperCIC pair mode entry for consoles with ≤ 3.072MHz CIC clock (notably GPM revisions). (Github Issue)
  • S-RTC register state is reset when the console is reset.

This Commodore Amiga 600 is arrived in laboratory in immaculate state still with the warranty sticker.

Immediately after the disassembly i have immediately noticed that were are several problems of acid released from the capacitors and dirty that affected this poor Amiga 600 and its Floppy Drive.

A decoupling capacitor it’s exploded with a pit on the PCB side, solved this problem i started to replace all the electrolytic capacitors and to clean the pcb with specific products.

After the replacement of the electrolytic capacitors, i have tried to turn on the amiga that apparently worked, shame about the distorted sound and the floppy drive that read 1 time of 100.

I had to replace the electrolyte capacitor on the Floppy Drive and soon after i looked for the fault of the audio problem that 99% is always the usual LF374.

In this case it was not only LF374 but also a 10ohm resistor that did not let the +12v to the LF374 and a short-circuited ceramic decoupling capacitor.

Components that have been replaced:

• IC LF374 substituted with a fully compatible TL084C (U15)
• 10Ohm resistor (R301)
• 330nF capacitor (C301)
• 330nF capacitor (C41)

Unfortunately the welding of the LF374 did not come very well how i like to do it but the pad are destroyed and corroded by the acid and they were about to detach, indeed the pad of the pin 2 of the LF374 was really detached, that’s why the pin 1 and 2 of the IC LF374 are connected together, they were connected via the pad.

I leave you to the photos and the video.
