THIS PROJECT HAS BEEN SCRATCHED!

Straight up RS-232 for the PSX. No USB.
This should help get those files and PS-EXE's uploaded for now.

Option 1 Includes: Populated board and 10 pin ribbon connector to PSX serial cable.
Price: $24.95

Option 2 Includes: Un-populated board, no populated board and no 10 pin ribbon connector to PSX serial cable.
Price: $12.95



IC1: SN74LS00 (DIP)
IC2: MAX232 (DIP)

I don't know much about electronics so... elements for that PCB-board are freely available in shops and i can just solder them? [without any programming/flashging or stuff like that, if you know what i mean].

Yes. The parts can be found online extremely easily, as well as in electronic stores.
You then just solder them. No need to flash the circuit.

So am i correct in thinking you are using DB9 connectors rather than USB A or B on the PSX side? Eg PSX -> USB -> USB -> PC? If so why wuould you use DB9 connector? would be much nicer to use USB ( especially MINI usb )

Went down that road remember. It didn't work well. Maybe i'll look into it later on...
This is just pure RS-232 from the PC to the PSX. This is pretty much a Net Yaroze serial cable replication.

Ok cool, this is great and all, ( i have one of these types of things, but far from being as nicely produced as you have ).. but are you going to consider a basic board to allow PSOne -> USB PC? I know Dans did this a while ago, im not really into the electronics side of thing, so not exactly sure what id need, so keen to see a project like that, would mean nothing more than a small PSone and USb cable to get going

Is it possible to use this device in combination with PC software to play "Link Cable Compatible" games over Internet?

No.

difficult to say, technically possible, but depends on delay between some kind of "packets" that sio used in protocol.

if create something faster ETHERNET adaptor for example or somthing more faster than sio, and then redirect function calls of sio to work with this device, its possible)))

Arrived today.

All finished. I have some debugging to do though, because it isn't working with SIOCONS -_-*
I have a feeling it's because I am only feeding the MAX's 3.5v and not 5v.
There are 3.3v 232's, but I will need to order some.
I can fix that for now by using the 5v rail on the MULTI-AV OUT.

Heya.

So wondering if you would consider coming up with a simple board using one of these

UB232R

http://www.ftdichip.com/Support/Documen ... UB232R.pdf

Pretty much would do the job to get a mini usb port on the machine. The board would handle any inverted signals etc..

Thoughts? Something you would consider for those of us who dont want old schoool 9 port serial connectors

Just wait for the PSX Blaster...
This was just a quick side project for some people to get their code uploaded for now.

looking forward

I'm not sure if using a bunch of transistors instead of MAX232 chips to convert the voltages will work. The country where I live sucks because there's no way I can acquire any MAX232 chips.

Theoretically you can make any IC with transistors. Google for it.
The inputs just seem to be going through inverters with pull-down/up resistors.

Thanks Shadow! Time to make an extremely lame excuse of a MAX232 clone.

You're welcome and good luck! Please share a photo of your progress as you build it

shadow,
you could run homebrew?
managed to do what?
