Hi all,
My RGB to PAL/NTSC adapter project is ready for sale. Full and comprehensive details, including photos are on my website:
http://www.amigamaniac.com
I'm selling them fully assembled from AUD$30 (no connectors), for Amiga & non-Amiga applications, to AUD$33 for a fully assembled and tested unit ready to use on an Amiga - just plug it in!
It outputs both Composite and S-Video.
Wow! Very nice indeed. I expect there are lots of Amiga users interested in this.
I am. Just need to check my funds, then might order one myself. :)
This is sweet. How long will you be selling these? I definately want to order one when im Back in Australia in December.
I'll be making them and selling them as long as people want them ;)Quote:

Wouldn't it require a different connector at the RGB end for other systems?
Have you considered making it a universal connector into the actual unit, and making different adaptor cables so the same unit can be interchanged between systems?
Yep, but by leaving the 23 pin D-Sub off, it leaves the holes available to solder wires too. There's detailed notes about how to use it on my website :)Quote:

I'm positive there is quite a large market for this device.
It is getting harder and harder to get hold of monitors that are capable to running the low resolution signals needed for vintage computers, so users are constantly looking at alternative solutions. For the A1200 an internal flicker fixer is one option, but being expensive these are non viable or just not affordable for many.
RF output, while bad quality, is also going to be a declining option as well, especially in the UK, and already in the US. This is because analogue TV broadcasts have already been switched off in the US, and in some parts of the UK, with all gone in the UK by 2012, meaning only digital TV tuners will be provided in new TV sets. Therefore old games consoles and computers won't be able to use their RF ports. So another output option will be gone.
This leaves the monitor output found on most old systems as the only option, and it is the best option for good quality visuals, so their users need a way to convert that output to be able to run it on a TV. S-Video, composite, and RGB SCART being the three main inputs needed by most users. With HDMI, VGA and DVI being something that is now being talked about, with many wondering if it is possible to convert to those inputs.
Regarding your adapter. Yes, I meant make the unit with a universal connector of some kind on the unit itself, allowing different adapter cables to be plugged in for different systems. The only thing that could cause a problem is that some systems do use different methods of output and wiring is different. Some need inline resisters to get the image right. Therefore adapter cables with the requirements for each system already setup would be a great solution. And you maybe wouldn't even need to invent and test these cables yourself. You could sell the unit and let those in say the ST community build the cables for them.

I took your advice onboard, and I have incorporated a plug into my RGB adapter V2.0 :) I'm very excited about the V2.0, and I should have them in stock in less than one month :thumbs:
Here is a picture of the top silkscreen to give you an idea of the new features (there is also some useful info on the bottom silkscreen which is not seen here):

That is great Nathan. I might be interested in one of these myself once you have them ready.
Keep up the great work. :thumbs:
Hi all,
I forgot to let everyone on Classic Amiga know that my V2.0 RGB adapters are now listed on my website for sale :) There are some photos of the new adapter, and a little info on the new features of V2.0. I just need to update the technical info page, as the data on there relates to V1.0. It's getting harder to find free time for my 'hobby', between uni commitments and the family :(

On a side note, I am looking at making another ROM switcher, one that my take three (or even more!) ROMS/EPROMS. I will announce developments accross forums when I have more to tell...
Sounds great.
Would you also be interested in making an Atari ST rom switcher? Not sure how complex that would be though as there are 2 roms involved, like AGA.
I love making hardware, and I will make it for absolutely anything as long as there is a market/buyers/interest :) I would just need to know the specs of the ROMS & their pinouts, and how the ROM socket of the Atari behaves on resetting the machine. I prefer to make ROM switchers that don't require a toggle switch, or a mini-clip that has to be attached to the leg of an IC on a M.B. Drilling a hole in one's Amiga or Atari (or any case) is wrong IMHO.Quote:

Although, A1200 users might like to select between KS 3.1 and KS 3.9 or something I suppose :)
I have limited knowledge in how the rom sockets behave on resetting the machine. However those on the Atari Forums should know. I will post on there to see how much interest there would be in an STE rom switcher. I know myself I would be interested to boot between 1.6 and 2.06 roms. Not sure if roms earlier than 1.4 would work in an STE, but if they did then I would love to be able to switch between 1.2 and 2.06 as that would give maximum compatibility.
