您仍然使用哪些古老的守旧学校代码？

最近几天请病假，我实在是太无聊了，所以我决定尝试挖掘一些旧代码。我可以找到我写的一些古老的 Atari ST 内容的二进制版本，但我找不到任何来源。我确实设法从传奇的旧 x2ftp 站点的存档中挖掘出许多个月前我在 ASM 中编写的旧 ModeX 库：

过去的爆炸:-)

还有人想让自己看起来很老并发布一些旧学校代码吗？ :-) 很遗憾我还没有任何 68000 ASM 的东西，尽管我现在可能都认不出它了！

啊..回忆:-)

Having been bored out of my brains the last few days off work sick, I decided to try and dig up some old code. I could find some binary versions of some ancient Atari ST stuff I wrote, but I couldn't find any source. I did manage to dredge up an old ModeX library I wrote in ASM many moons ago from an archive of the legendary old x2ftp site:

http://ftp.lanet.lv/ftp/mirror/x2ftp/msdos

Blast from the past :-)

Anyone else want to make themselves look old and post some old school code? :-) It's a shame I don't have any of my 68000 ASM stuff still, although I probably wouldn't even recognise it now!

Ahh.. memories :-)

有一船旧的 Atari 8 位 BASIC 和 Atari ST 的东西（我仍然有 ST，但它没有联网，所以我很少使用它）。

我曾经输入过 David Ahl 的《BASIC Computer Games: Microcomputer Edition》中的大部分游戏，并将它们移植到 8 位和 ST BASIC 上。

我有点想将这些旧游戏移植到Processing/Arduino，以获得老式的乐趣。

我有一个 MUD，是我在 1990-1993 年大学期间编写和维护的。都是C。那是迪酷MUD的一个衍生品，叫SillyMUD，是我当时的骄傲和喜悦。

您仍然可以在 Intertubes 上到处找到该代码。

我从 Atari ST 获得的大部分代码都在 GFA-Basic 中，我不想碰那些布满灰尘的软盘。
