SIO2OSX on OS/X 10.9.5 using Cheap Prolific2303 Adapter

[Isonium]

I got SIO2OSX working on OSX Mavericks 10.9.5 with an $8.77 USB-to-Serial Adapter (using the Prolific 2303 chipset)...

 

I used the default SIO2OSX configuration except I selected 'SIO Hardware Type' of 'DSR' in preferences.

 

I suspect other software would work as well...

 

Don't know if this will be useful to anyone else...

Yeah, I forgot about that, it is a developer release but it should also work on 10.9.x as well as 10.7.x and 10.8.x... I will also test it on 10.10 Yosemite beta probably this weekend.

Thanks Isonium.

 

Just to warn people the shipping price is crazy for this item. The actual total was $18. Still a good deal though (as long as it works)

 

I'll post my results when I get it.

Oh, I have Amazon Prime so shipping was free. You can get a free trial of Amazon Prime. I was unaware of the cost since on prime it just shows as free.

It may be my set up, but I notice if I drop the speed to 19,200 in SIO2OSX I get overall better performance. I notice on higher speeds it is faster per sector but gets more errors this slowing it down a bit. Each setup may be different as I hear you really need to pull the capacitors out of the Atari to push higher speeds. I have a fairly long cable and that may be part of it as well.

I have tried several other cheap adaptors with little luck. I know the more expensive FTDI adapter are said to work very well. I have not tried those.

Thanks Isonium.

Did you get it working? It also works on OS/X Yosemite 10.10 (Developer Preview as well.

There are other suppliers besides Amazon listed, KOOTION has it for only $7.03 + $1.99 shipping.

I would be somewhat cautious about 3rd party sellers. Sometimes they sell knockoffs or what they consider equivalent items. I see this a lot in comments on some items. I would check the comments carefully to see if anyone has complained.

Cool you got it working! $50 is pretty pricy for me. My OSX-based rig uses an FT232RL USB->TTL serial breakout board, a butchered SIO cable and a mini-USB cable. Cost about $15 to make. Works fine with most OSX releases back to 10.4 with driver package. On an unrelated note, these little boards are incredibly handy for adding serial consoles to cheap Linux-based routers like the Linksys WRT54GL too.

 

I should start stuffing these little breakout boards in cheap project boxes with a male SIO connector and sell them for $35 on ebay.

I paid a total of about $35 (total shipped) for the SIO2PC and the USB to serial adapter.

 

I am actually making an internal version using a FTDI breakout board, mini-grabber clips, and a flat retractable USB cable. So, no permanent mods to the Atari, easy to install, and pretty cheap. I will post pictures when I am done.
