Multicomp Cycllne II-C で先日flex, Nitros9を動かしたが、それだけではもったいない。同sdでFUZIXがあるので試してみた。
電源を入れるとCamelForthが起動する。そこでFUZIXと入力すると起動。
知らなかったが、調べてみるとfuzixは結構有名。8bitCPU Z80, 6809, 6502 などで動くunix likeなOS。
(バンクでのメモリ拡張は必要だが)
unix likeというだけあって、良く使うコマンドは大概使える。

8bitCPUでこれだけ動くのは素晴らしいが、unixに似ているのだが微妙な違いが引っかかる。(例えば日付の合わせ方がわからない。説明が見つからない。manでも登録されていない)。これなら母艦のlinuxで良いじゃないという気になってしまった。
他に気になったのは、バックスペースがうまく動かないところ。
stty -a では以下のように表示されるが、baud rateは9600ということはないし微妙...

github上にソースがあり読めば色々おもしろそうだが、各種platformに対応しておりややこしい(github上にsetdateのソースはあるが、このSDには入ってないし)。もう少し調べないと。
