Beta 4 Question about Chip - GSM-Forum

Pampersrocker · 08-24-2012, 17:51

Hi there,

i've got an Grundig Beta IV VWZ2Z2X4429565 on my table.

I think i have to look for the MC68HC11E9 to read.

But i can't find this chip. I've got two Motorola Chips.
On is a smaller 16 pin MC33074D and a bigger one with the title: "Motorola VW BETA 4 by Grundig 4E28B SSAB9850"

Which one of the two chips do i have to read?

Equipment is available.

Not my first Radio. But the first Beta 4

Thank you.

Best Regards

Hi!Pin 1 is GND and must put pin 2 also to GND because is modeB.And you can use Motorola cracker software and interface to read the mcu.
