First RGBS to YPbPr converter finally came out of pre-production

This is ou very first “pre-production” RGBS to YPbPr converter. Signal to noise ratio is exceptional and video quality too. It was fully tested on a video output from an Amiga 2000. It can be connected to any machine that outputs in RGBS standard, in both NTSC and PAL like arcade motherboards in cabinets, Sega Genesis, NES and Super Nintendo systems, Amstrad CPC, Atari ST and many many more.

External floppy drive adapter prototype underway

We’ve worked hard recently to build an external floppy drive adapter for the Amiga familly of computers.  It uses a male DB-23 connector and a female 34 header to externally connect three type of drives:

  • Gotek USB floppy emulator (HxC and others)
  • Amiga “Shugart” floppy drives
  • IBM-PC compatible floppy drive (in Amiga 880KB format).

Using a simple jumper configuration, you can connect these three type of drives externally.

Full production should be available Q4 2017.

New RGBS to YPbPr video adapter prototype

After a long prototyping, testing and validating process, we finally have a perfectly working product without needs for calibration. Secret is that we designed around a gaming console video converter IC. This IC has been around for a long time now and has a perfect, noise free output.  It works with both 240p and 480i NTSC formats. It can also work with PAL 50Hz formats. No color bleeding on vertical edges nor flickering in interlaced mode. It’s even better that the original thing on a CRT!  My workbench screen of my Amiga 2000 is crisp and bright!

If everything goes well, it’s going into full production by Q4 2017.

RGB to YPbPr conversion vs new LCD TV

During my tests with the new RGB to YPbPr video converter I discovered an interesting (but painfull) limitation with new LCD TVs.

Amiga and most machines of ’80s and ’90 have a video output of 240p in resolution. This 240p corresponds to the “non-interlaced” 480i mode which was known under that name back then. Amiga native video mode is 240p but can be set to 480i. Remember that only 200 or 400 lines are usable in non-overscan mode.

New LCD TV are not equally compatible to this 240p video mode. My Sony Bravia supports it while my Sanyo don’t. A very nice article was written on this subject on the HD Retrovision website with a list of tested LCD TV.

Refert to that list to see if your LCD TV is “Amgiable”
