NEC IFU Power supply

[fredJ]

hi,
I have the NEC "Inter Face Unit" that requires a DC 9V 1450 mA power supply, center negative.
The IFU works well with just 1000 mA 9V if I don't use the CD, and that should not be a surprise.
But I assume the CD, that is currently broken, requires more juice.
Anyone knows how much ampere that is essential, or if I can run it with center-positive polarity?
It is a bit difficult to find the required power supply.
I know a can change polarity myself of the PSU, but that may not be appropriate in case I should sell it.

retrogamecave products are great quality, but they never seem to have the turbo express power supply in stock.
