 ====== ZZ80RC-CF, Enhanced ZZ80RC ======
+**Note: ZZ80RC-CF and its close relative [[builderpages:plasmo:zz80rc|ZZ80RC]] are obsolete because of an asynchronous serial clock bug of Z280. The replacement design is [[builderpages:plasmo:zzrcc|ZZRCC]].**

-UART Bootstrap software, [[https://retrobrewcomputers.org/lib/exe/fetch.php?media=builderpages:plasmo:zz80cf:loadngo.zip|LoadnGo.run]], loads the 256-byte bootstrap first which, in turn, loads ZZ80CFMon and transfer control to it. If TeraTerm is the terminal software, set the serial port transmission delay to 1 msec/line and check the 'Binary' box in 'Send file…' menu. **The transmission delay and checked Binary box are necessary only for loading LoadnGo.run. All subsequent file loads are with zero transmission delay and Binary box unchecked.**

+For Windows users using TeraTerm terminal emulation software, this [[https://www.retrobrewcomputers.org/lib/exe/fetch.php?media=builderpages:plasmo:zz80cf:zz80cf_all.zip|zipped file]] contains all the programs above and a TeraTerm macro to load the program serially into the CF disk. This is an automated process that takes about 8-10 minutes to run. Unzip the files into c:\teraterm\zz80cf. While in ZZ80 monitor prompt, go to TeraTerm menu “Control→Macro” navigate to c:\teraterm\zz80cf and select “newzz80cf.ttl”. The macro will do a quick test; format drive A/B/C/D; load CP/M2 and CP/M3; copy XM.hex; start CP/M2; save XM.COM; use XM to load CP/M2, CP/M3, Zork; decompress CP/M2, CP/M3, and Zork into drive B, A, D.
