[sdiy] string machine technology?

[Loscha]

I was told by a Roland service guy in Sydney that the RS-202 was
almost exactly the same as a VP330, and that all the "rare" silicon
inside it was common.
 The conversation came about because I was interested in Laurie
Anderson, and her use of the VP330 in the Oh Superman piqued my
interest.
 An RS-202 was in a local shop, and I really liked the sound of it.
Someone remarked that it came out at the same time as the VP330. I was
wondering if I got the VP330, and a hardware Vocoder, if I could sound
just like Laurie.
 I had to call Roland Service to get the schematics for a Dr-110 I'd
been given, and I asked the techie about the VP330 vs RS202. He told
me when I wrote above, however, It was going to cost me more money
than I could afford to get both those schematics.

 I didn't end up getting the RS-202, shame, was only $125 - but, this
was back in 96 when I was exceptionally poor.

 I would like to see the schematics of both side by side to confirm
this, though. I wouldn't take what I have written as Gospel, it is
based on the experience of talking to One techie, one time.
