Should I use 7-year-old Sonar Power Studio 660 or start over?

[JLCMLC]

I have a SONAR Power Studio 660 that I bought in 2006 (and used only once), which originally included SONAR software and used a SPS 66 with firewire interface.

My 2 problems:
1) I have lost the SONAR software that came with this device and
2) I also no longer have any computer with a firewire port (seems awfully difficult to find on a PC nowadays).

I understand that Firewire to USB adapters don't work right. I suppose I can buy a firewire PCI card for my computer (they don't seem to come installed anymore), and I can buy the new Sonar X3 if necessary? But I'm interested to hear from your wisdom: Given the range of options available today, should I bother trying to adapt this machine (it's in new condition, used only once) or should I just start over with a new standalone multitrack recorders or PC-based systems. At least when I bought it, the Power Studio was ~$600 and reasonably good quality consumer-level system, but I don't know if present-day low-end products (wouldn't want to spend more than $400 now...) are better?
Also, I wonder if the SONAR SPS 66 requires SONAR brand software, or if I can get it to work with free or cheap software?

BACKGROUND:
-- I am interested in making simple acoustic recordings (2 vocals and guitar) for home purposes. Lullaby for baby (with moderately sophisticated ears).
-- I have an Audio-Technica 'studio pack' (AT2020 side address cardioid condenser mic and AT2012 small diaphragm condenser mic).
-- I use a Windows PC.

Thanks!

Dont know if I can post links here, but this is a description of the SPS 66 audio interface.

I'm curious to hear how this compares with something like a TASCAM DP-03 Digital Portastudio standalone or some other system in the <$400 range, if I'm interested in a cheap, good-sounding, simple-to-use system for recording acoustic music w guitar and vocal. I wonder about issues like latency, versatility, features, etc.

Double check your PC, on desktops they are referred to as the 1394 port. (Just in case)

I've been looking at portastudios myself. Couple of people have given the Zoom systems some good reviews.

SONAR Power Studio 660 from 2006

Thanks. I'm buying a new desktop, and believe 1394 ports do not come standard. I can have one installed or do it myself, but it will only make sense to do so if the Power Studio 660 is a functional product in the 2013 world. [Typically, I consider any 7 year old computer equipment to be usable only as paperweight/doorstop.] Also considering the fact that I have lost the original SONAR 5 Studio software and don't know if this old hardware will work (as well) with something like Reaper or Audacity, which I could get today?

From a 2006 product review of the Power Studio 660:
"includes a six-in/six-out interface capable of up to 192kHz sampling that connects via FireWire... the full version of the SONAR 5 Studio Edition software (64 bit) -- not crippled LE versions... includes MIDI I/O, optical digital audio I/O, two RCA inputs, two dual-purpose XLR/phone plug jacks, 48v Phantom power for microphones, a 1/4-in. headphone jack, and a Hi Z switch for recording guitars and other high impedance sources. A user-selectable limiter is also provided... 102 db signal-to-noise ratio on the inputs and 105 db on the outputs... zero latency monitoring... Sens dial beside each of the XLR/phone jacks, which is used to set good absolute input levels... Soft Control [button] allows the volume, panning and on/off status of each jack to be adjusted from SONAR 5's onscreen controls when using ASIO drivers... four 1/4-in. output jacks, the two RCA output jacks, the optical jacks, the MIDI I/O jacks and two FireWire ports... on-off switch on the rear selects bus or conventional power... limiter switch adds a gentle compression to signals that exceed the threshold of distortion."

The I/O is sufficient for my uses, and I'm not aware of a needed feature that this product is missing. I'm open to getting something like a portastudio or something else if this product is a dinosaur, but I'm wary of drawbacks that I may not know about (like latency or something else) for buying lower-end consumer grade products. No idea if I would be better off just trying to adapt the 2006 product for today's environment/recording software or starting over?
Thanks!
