C64 tape duplicator - vintage hackery for Zetr0, rkauer, etc

I see you are on vcforum too, you guys are everywhere

Hey, if it's retro and computing, we are all over it like a cheap suit.....what's wrong with that? EAB and the guys at VCF shared experiences along with Atari-Forums and other retro sites when we worked out Retr0bright, so why should the retro community be compartmented off?

We are like Woody from Toy Story; we see EVERYTHING......... :wooha:

:woot:

Can we please try and keep this to a technical discussion of my project, please?

Arkanoid has been good enough to temporarily dismantle the unit he has and here is some more 80s retro nekkid amateur hardware pr0n for Zetr0 et al to lust over....

Warning! Totally topless and naked circuit boards below!!

From these, it's conclusive that the large boxes are power supplies. I also think we correctly figured out how the gates on the 7416 were arranged, although I need a 'coffee and paracetamol' moment to dissect the unit fully.

This, after a LOT of coffee, Paracetamol and Photoshoppage, is the circuit diagram for Arkanoid's unit, as far as I can make out:-

I've asked Arkanoid to check the circuits are mapped correctly and to confirm the colour codes of the resistors as they weren't too clear on his photos.

No worries, Charlie....... I'm just trying to stop this from going off at tangents.....

Arkanoid came through with the colour codes for the resistors and enough info to identify the values of the capacitors, so here's the final diagram as far as I can ascertain, with the values added:-

[attachment=0:cpoakhtr]Arkanoid.jpg[/attachment:cpoakhtr]

One thing I don't understand from this; pin 1 is an input and 2 an output, yet the input from pin 1 doesn't output on pin 2. Can anyone explain why all of the LEDs apparently work with this arrangement? It doesn't seem to make much sense.

@Merlicious

to be fair m8, that schematic is on crack, stick with the one you have developed me 'ol mucker and I believe it will work.

I have included some 7416N details

@ Z

I know what you mean, mate; I kept going over and over the photographs and enhancing them for more detail, thinking I was screwing up, however, that diagram is 100% correct based on the photographs and arkanoid did his best on determining the colours of some really ancient resistors.

The only reason I did this was to preserve the design of the device Arkanoid discovered.
