I have a Motorola MC1463G here. 200mA adjustable negative regulator in metal can.
New old stock, date code 7430. I've no way of testing it but you are welcome to have it for the postage cost.

I dug through my collection of old Motorola power-regulators but was only, alas, able to turn up a MC1469R which is the positive-voltage version.

That IC had been hanging around in one of my component drawers for years, with little to no likelihood of my ever finding a use for it.

Thanks to this forum (i.e. Paul and his volunteers) for finally enabling it to put it to good use!
