Well, c't went the way most mag's do today: Everything that is Messydos is
HEAVEN and everything else (especially CP/M) is HELL. Last few issues, they
even bashed CP/M in *every* editorial. Hard- and software articles about
Z80/180/280 and CP/M weren't published for a long time, and (I guess) will
never be again.
But there are some CP/M groups here in germany being still active with hard-
and software. For example, I just designed a Z280 single board (europe card)
computer capable of running CP/M+ without externals (Power, floppy and
terminal, of course). Fits onto ECB bus (64-pin VG connector), and contains
64/128K EPROM, 512K/1/2/4M DRAM, FDC, RTC, NVRAM, 2x RS-232. Clock speed
12.288 MHz, as soon as 12.5 MHz CPU is available. Meanwhile 9.8304 MHz.
CPU runs with 16-Bit Z-BUS, the DRAM circuit supports 'Burst Mode'.
The prototype board works very well, I'm now implementing my (180-proven)
autoformat-BIOS for CP/M+ and re-layouting the PCB.
Cost of the 'naked' PCB is supposed to be under $50.
