Help needed for Vlab External

[Rabbi]

Hi fellow Amigans,

     I recently picked up a Vlab External for my A1200 (NTSC).  It's not the Y/C later version.  I've got version 4.2 of the driver.  Is this the latest & greatest version or is there something more current?  Also, I need help with the P/S.  What is the proper:
1) voltage
2) minimum amperage
3) polarity of the tip?

If someone out there has one that's currently in operation, your knowledge is greatly appreciated.  I'm still looking for a Vlab Y/C External to purchase, BTW.  This will have to do until I get one.

4.2 was the latest.
Thinkin' ya don't have the manual that came with the V-lab. It might have the info you need for the power supply.
