Catweasel Z-II Mk2 (Urine CAT Cleaning)

Defect:

  • The card is not recognized by the computer.

Cleaning:

  • The Catweasel has traces of cat urine that with time has crystallized causing corrosion and short circuits.  I used the KONTACT PCC & Toothbrush to clean. I also checked the continuity in holes between pcb layers and traces in general.  Now it seems to work properly.

Peggy Plus (Scala MD100) v1.1 Recap

Peggy Plus (Scala MD100) v1.1 Recap

This Z2 card for Amiga has a problem of audio distortion on one channel. I have replaced all the tantalum capacitors, two of them in the Audio section.

Unfortunately i could not try this card, i did consider that could be also a problem of the NE5532  a Dual Low-Noise Operational Amplifier so i preferred put it on a socket, so it’s easy to replace if it is needed.

C64 Reloaded MK2 (pre-production)

July 13th, 2017 No comments

The Commodore 64 Reloaded MK2 is a C64 Motherboard for building a C64 on your own.

The board is shipped with empty ZIF sockets for the key chips such as CPU, port chips, sound/video chips. All other components are already assembled and pre-tested before shipment.

As opposed to the first C64 Reloaded board, the C64 Reloaded MK2 will automatically identify the installed chips. It will not only generate the correct clocking, but also set the right voltages for the chips that you have chosen. Further, it configures the filter-capacitors for your favourite SID combination. This means that the Commodore 64 Reloaded MK2 is a completely jumper-free design.

The Commodore 64 Reloaded MK2 includes the following on the board:

  • All memory
  • Flash rom for Kernal, Basic, Character and your own sets of ROMs
  • Clock generator equivalent to the CSG8701 chip with two custom crystals
  • PLA equivalent to the CSG 906114-01 chip
  • Stereo-SID circuit configurable for three different popular addresses
  • S-Video and 3.5mm stereo outputs
  • USB to serial link for configuring the board with a terminal program
  • High-efficiency power conversion for operation from a single 12V supply
  • Power switch with integrated reset function
  • Six all-black high quality ZIF sockets

Ultimate-64 (prototype) by Gideon

July 12th, 2017 No comments

Directly from the author;

It’s time to announce the upcoming new “Ultimate-64″ board by Gideon.

In order to sustain the love for the Commodore 64, with failing machines, power supplies and flaky old connectors, I proudly present a new main board for your beloved C64 case.

This board is a hardware implementation (FPGA) of the entire C64, and it includes the Ultimate-II+ as well.  An ALL IN ONE solution!

Hyperkin Supaboy S (SD2Snes & Hardware Gallery)

Hyperkin Supaboy S (SD2Snes & Hardware Gallery)

I think it is totally useless to make another review of the Hyperkin SupaBoy S, there are hundreds on the net.

I wrote this short article and made a short video just to confirm the compatibility with the SD2Snes cartridge and take some photos of the inside of the SupaBoy S.

The SupaBoy S is not a Super Nintendo/Super Famicom emulator but a hardware clone of the original console, other consoles like the Yobo FC Twin had used the same choice.

This choice is absolutely winner because the compatibility with the software is very high, i have tested some games without any problems, including MSU-1 games with CD-quality Audio and Video Movies.

The only painful note is the video signal,  external and internal because BOTH are composite, which is not really the best, they could do better, maybe take the RGB signal immediately after the SONY CXA 1645M video encoder and make it available externally with a video connector.

I leave you to the photos and video.
