Indeed, the quick reference only scratches the surface of how cool the Cleuseau ROM is.
I like the ability to quickly find matching lines, grep-like, using `.LIST =foo` and it is great that the same syntax works for setting debugging points. The various BASIC compaction tools (DELCOM, SQUASH, PACK, MIN) are nice, but I was surprised that `.EXPAND` is also handy; it splits long lines filled with colons into multiple lines which is just what you need for setting `.STOP` points for debugging. The `.RENUM` command is smart and treats lines which only have a REMark as anchors and doesn't renumber them, since they are usually the start of subroutines. And, of course, a `.FILES` command that actually shows file sizes is something the Model T computers should have had from the beginning. Oh, and I almost forgot to mention the major changes to the TEXT editor -- you can hit ^X and any key to get help on it, or ^X ^X to see every key's function. (The one thing I dislike about Cleuseau so far is in the editor: they hijacked the Esc key into a "Repeat" function, so now I have to use F8 to exit. Bleh. I hope I can find a patch that lets Esc Esc exit like usual. I do like that they let you switch back to the Microsoft version of TEXT by just hitting ^J.) And that only covers the Cleuseau half of ROM2/Cleuseau. I'm looking forward to investigating the ROM2 side, which appears to have a powerful macro assembler with a debugger that can simulate the 8085! The truly crazy thing is it seems that both ROM2 and Cleuseau together take only half of the 32K ROM. Giants walked the Earth in those days, I tell you. —b9 P.S. Does anybody know if the hex file of ROM2/Cleuseau for the T200 on Club100 <https://www.club100.org/library/librom.html> actually works? I tried it with Virtual T, but it would lock up every time I tried to set a breakpoint. When I replaced it with the same ROM file that has been working on my actual Tandy 200, R2C2D.BX via REX, Virtual T had no problems. I notice that the internal copyright date for the Club100 version says 1985 and the version bundled with REX is 1987, but I'm not sure they can be compared that way. It appears R2C2D is the Developer's Version which has different features. P.P.S. I've added a few extra BASIC Inspector examples to the quick reference guide <https://archive.org/details/cleuqr/page/n1/mode/1up> since there was extra space. I hope folks don't mind. I did not remove any of the original information and refrained from unnecessary stylistic improvements. On Tue, Oct 13, 2026 at 4:15 AM Brian K.
