I am wanting to get that, and I am watching one on eBay, but those things are so overpriced, it's a killer...
Am I able to daisy chain the SIO2PC out of the SIO port on the 1050? If my OS is on the thing I would think that would be important, but I heard something about the SIO2PC using all IO channels for virtual drives and I don't know if that would conflict with the physical drive, being on D1 currently.
I actually did get a strobe light today, I can fine tune it too, it's excellent. I just need to know exactly what to tune it to. It gives me a digital readout on the top of the strobe, I -think- that it displays rotations per minute. I could be wrong. What do y'all think? It's this expensive thing: http://www.grainger....0140123191932:s
'Am I able to daisy chain the SIO2PC out of the SIO port on the 1050? '
Yes. You would boot from SIO2PC/APE .atr with your real 1050 set at D2:. You would plug your SIO2PC into the 1050 and the 1050 into the computer.
There are instructions for making your own SIO2PC. It uses a max232 or 1489.

*NOTES: If you're positive the cable will never be used with other
peripherals like a 1050, you don't need the diode. If you do use a
diode <recommended> make sure it has a low forward voltage. In the
prototype I tried one with a 1.2V forward drop & it failed to operate,
but a diode with a .65V forward voltage drop worked like gang busters.
This means you can surely get away with any germanium diode & probably
most small signal diodes like the 1N914.
NC means not connected, you don't tie it to anything. Only pins 13 & 14
are tied together. If you feel bad because the thing is too easy, you
can add a few more parts like a .1 Micro Farad disk capacitor between
pins 14 & 7 for decoupling. The funny \ /
o on the 1489 are just an
attempt to show the inverting logic of the 1489. All parts can be had
from your local Radio Shack, but once again, I hate Radio Shack & would
recommend going anywhere else. The SIO pin out when looking at the back
of the Atari is
2 4 6 8 10 12
1 3 5 7 9 11 13
Colors I've found in addition to what Nick Kennedy found
4 & 6 Black & or bare wire. Both of these are grounds, one logic & the
other shield. If you really want to be sure you have a good ground you
can use both of them. Black wire is pretty safe if you're in a hurry &
don't want to bother.
10 +5V Blue in every cable I've seen.
5 DATA OUT It's Green or Dark Green on cables with two green wires.
7 COMMAND Violet on some, light green on others.
3 DATA IN & I don't think it comes in any color but orange.
That's it, 5 connections to the Atari serial cable, 4 to the IBM serial
cable, 1 chip, 1 diode. The IBM connector will have the numbers on the
plastic, but you may need a magnifiying glass to see them. If somebody
wants help building a cable, you're better off asking me about this one
vs the MAX or 7400 as I'm quite bored with them & this circuit is IMO:
The obvious way to go.

I'm not sure that formats correctly the chip pins. Here's a txt file.
