RCBus/RC2014とエコシステムについて（その２）

　RCBus/RC2014とエコシステムについての続き。

　RCBus(Retro Computer Bus)/RC2014の名の通りZ80系/6800系/TMS9995系/その他の所謂８ビット系レトロマイコンのBUSとそのエコシステム（というか２０２５年で購入可能なECサイトと各種ボードの情報）を引用させてもらいましたが、いづれも

　１９８０年代（当時）の若者？か懐古趣味のジジババ（実質的に両者は同一：）向けのCP/MだのLocal Basicインタプリタ移植だのといった１９８０年代風のアイテムが主題な訳ですが・・・

最近地味に話題になりつつあるFUZIXが動作するハードウェアが上記RCBus/RC2014に存在する様です。対象はZ80、Z180系の様ですが（以下はFUZIX.orgから引用）：

RC2014

There are two Fuzix ports aimed at "official" RC2014 targets.

The RC2014 port requires a 512K RAM/ROM card and supports the bigger RC2014 configurations along with a lot of other compatible RCBus hardware.

The RC2014-tiny port is a "because we can" port that puts the core of the Fuzix kernel in the pageable ROM and pages it in and out in order to run Fuzix on the 64K + pageable ROM setup. This works but isn't recommended. Note that you can (and should!) jumper the ROM card for a 28C256 not a 27C256 part if you are doing this, that way you can quickly erase it and update it.

RCBus (Z80 and compatible)

The following RCbus compatible systems have their own ports referenced elsewhere in this document.

2063 (with adapter)

Easy Z80

RIZ180

SC108

SC111

SC720

Simple80

T68KRC

ZRC

The SBC64/MBC64/ZRCC have their own rcbus-sbc64 target. In general the other Z80 boards are compatible and operate with the RC2014 tree. This knows how to handle Z180 processor cards with the banked memory card, and various variant systems and I/O options.

The rcbus-z180 target handles the many near identical flat Z180 designs that use the RCBus with a 512/512K flat 20bit memory space as well as the modification sometimes used to allow for 1MB RAM.

RCBus (Other)

There are specific ports for RCbus systems with the following processors: 6303 (and 6803), 6502, 6809, 8085, 68008, NS32K. The card requirements vary by port. Please consult the port documentation for detail.

　最後のパラグラフは間違いではないのですがECサイトでボードが入手可能な訳でも無いので念の為（回路情報はリンクがあるものは追跡可能・・・再現出来るとは言ってない：）

　具体的にZ80系のそれについて同じくFUZIX.orgから引用すると：

SC108

Small Computer Central design with CPU, RAM and OM on one card. Also supports the SC114.

SC111

Small Computer Central Z180 design. This tree has been kept apart from the unification of various related Z180 RCbus systems because it also supports the ability to boot from SCM firmware. With RomWBW firmware the SC111 can run either.

SC720

Small Computer Central Z80 SBC. Has a different more limited memory mapping model to the standard rcbus systems.
