Hi MacRorie.

 

I plan on ordering a few UAVs next month, but I will need an audio circuit.  What is the status of the Audio Companion board?

 

I know there are other circuits out there, but it would be much more desirable (for me) to just order the boards along with the UAVs.  (Honestly, I'm not even sure what boards are available.  While I'm not afraid of wiring up a circuit, a premade board is just easier and cleaner.)

 

Thanks.

I want an audio companion board too 

 

ive fitted the UAV board - I foolishly thought the A in UAV was Audio

 

any idea if these will be available soon?

 

thanks

The Audio board is a completely different upgrade that Bryan made. I have reached out to him about it. Will keep you informed.

 

I would like to include this write up in the manual that gets sent out, if that is okay.

 

Fine with me - i hope it will help someone

 

Yeah - I have good composite pic now - just need the AC Audeo board

 

email me if you mange to source this - make sense to me if you can get this from Bryan. Audio & Video :-)

 

All the best

Atari 400 XL – Update and Sound Question

 

Hi Guys

 

I never owned an Atari when I was younger but always coveted a friend of mine’s unit.

So, when I has the chance to buy an Atari 400 for not too much – I jumped at it.

So – Please excuse me for being ignorant of things Atari here…

 

I tried to get an RF picture on the unit when I bought it and could not – I could hear the unit clicking when pressing keys – so I surmised that it was working.

 

I watched the you tube video from “Perifractic's Retro Recipes”

 

https://www.youtube.com/watch?v=JG_9W-LzWXc&feature=youtu.be

 

And so I purchased one of the AV mod units from the Brewing Academy – This arrived and I today looked into getting this fitted.

 

If you have a 400 XL, this ‘might’ be of help - Here’s what I did:

 

• Open the unit & disassemble – be careful not to snap the little tag at the bottom of the keyboard. Remove the power board, metal casing and take the RAM & processor boards from the main board.

So you now just have the main board

• Set the jumpers on the AV mod board to the 400 XL positions (see instructions)

• Take a piece of link wire - around 3 inches in length. Strip a few mm off each end to expose some wire. Solder one end of the link wire to the ‘inside’ leg of capacitor C187

• Remove the chip marked “TC4050BP” and put the new Video mod board into the socket.

 

• Put the other end of the link wire into the green connector – the outside terminal

 

• Then take a single phono wire – about 1 / 2 meters of cable and strip the ends to expose:
  • The outer shielding – Put into the ‘Ground’ terminal – The inside terminal
  • The centre Core – put into the ‘Composite’ terminal – The next one in

• Remove the RF lead from the case of the machine and put to one side.

• Then reassemble and the machine, finding a suitable path out of the metal casing and out of the back.

 

• This should give you perfect AV composite signal from your 400 – It did for me anyway..!

 

Now here’s my ignorance and the subsequent question…

 

Ignorant bit – I saw the speaker when disassembling the unit. I thought...

‘Ah, it’s like the BBC Micro and early spectrum. All sound output must come through this on-board speaker”

 

Never having owned one – I did not know. But I don’t this is the case as when playing Star Raiders it’s in silence.

 

I re-watched Perifractic's video and I then saw he had an additional AC Sound mod board that he purchased from Brian here an AtariAge.

 

I checked the packaging and I don’t seem to have been sent this board.

 

Here’s the question(s):

 

Do I need this AC Sound mod board?

Is all of the above all correct? My fitting and assumptions??

If so – Can I get one??

 

I’ve checked the brewing academy website an cannot see one

 

Is it the Audio Companion board that i need that is here:

Please advise me

 

Thanks

 

Baz

 

 

PS – Does anyone have a 6 Volt power supply for an Atari 410 Program Recorder (tape deck)

(I'm in the UK)

Hi Bryan

 

When things have settled in your personal life - I would very much like to order one of these for my poor ailing Atari 400 unit.

 

Please let me know info regarding payment etc...

 

Many Thanks & Good Luck
