and my last addition to the family for a while i think...
A 1980 CBM 4032
4032 refers to 40 character display, with 32K RAM memory.
The PET 4032 was released three years after the original PET 2001. Although it has the same CPU running at the same speed, improved circuitry allows the 4032 to run substantially faster. Other improvements include more memory and a better keyboard.
The 4032 has four port to the outside world. An eight-bit parallel port, a port for a cassette recorder, a port that brings out the system bus, and an IEEE-488 port. Still in use today, but mostly for laboratory and scientific instruments, the IEEE-488 bus is relatively complex, allowing up to 15 devices on the bus.
The pet is a non-runner with a smelly PSU and no life yet .... the volt meter and soldering iron will be out over the weekend to make the old girl live..
The monitior does buzz for 2/3 seconds then goes quiet. the PSU gives off a rancid smell but outputs 8v 18v AC ...more checks later.
