Magazines for those interested in Z80-Family

AFAIK there aren't (m)any heavily Z80 oriented magazine left, but from time to time there are articles with Z80 related stuff or with stuff adaptable to Z80 based designs.
If you know of more (in whatever language), or if you have URLs of sites archiving old (or new) magazines which may be of interest for Z80 users, please tell me.

  Subtitle: Embedded Controllers Get Respect

  Issue: 8 Apr/May 1989
  Page: 52
  Author: Tom Cantrell
  Abstract: While the state-of-the-art marches toward 32 bits, 8-bit
  	microcontrollers keep getting more powerful. The HD647180X is the
  	latest integrated controller built on the foundation of the proven

• Title: Silicon Update
  Subtitle: I'm 18.432 -- and I Like It

  Issue: 29 Oct/Nov 1992
  Page: 80
  Author: Tom Cantrell
  Abstract: Some people just can't get enough horsepower out of their
  	processors, and Tome is certainly one of them. Zilog's newest speed
  	demon runs the faithful Z180 (HD64180) up to 18.432 MHz and beyond.

• Title: Silicon Update
  Subtitle: Flight of the Phoenix

  Issue: 72 July 1996
  Page: 74
  Author: Tom Cantrell
  Abstract: Zilog has risen from its ashes. It offers the S180 processor along
  	with an evaluation/emulation board. Ironically, it's a chip off the old
  	Z80, CTC, PIO, and SIO, the cornerstones of Zilog's glory in the 1970s.
  

• Title: Updating a Classic: the Z80380 Microprocessor

  Issue: 67 Feb 1996
  Page: 12
  Author: Monte Dalrymple
  Abstract: After reviewing the Z80's popularity, Monte introduces the Z380, a
  	new chip offering a full complement of 16-bit data manipulations and
  	enough 32-bit instructions to handle the new 32-bit addresses.
  

• Title: A Simple RS-485 Network
  Subtitle: Exploit the Nine-Bit Serial Communication Modes of the 8051, 8096BH, 68HC11, 68HC05, and Z180 Microcontroller Families

  Issue: 21 Jun/Jul 1991
  Page: 38
  Author: Jim Butler
  Abstract: RS-485 is a perfect standard for networking controllers. A solid
  	strategy for network design makes the job easier, and the result more
  	powerful.
