Help Toshiba TMP90C840AF

[petrus bitbyter]

I'm looking for information about the Toshiba TMP90C840AF.

For all I know it's a Z80 like 8 bit mpu that Toshiba sells (sold) and also
used in some of their own products.

I Googled a lot but I could not find anything but parts sellers. No info,
not even a pinout descryption.

As I have to do some work with it I like anything you can tell.

It's in their 1990 8-Bit Microcontroller databook. But it's 161 pages
on just that part!

Yow. Two stepper motor control ports, serial port, 3 timers and 5
other I/O ports (which can be used as an external bus). 256 bytes RAM,
8k bytes ROM.
