about 《Revenge of the Son of the Lisp Machine》 Appendix

I have read this paper.

I encountered a problem when I tried to run the code at the end.

After reading this article

, I added at the beginning

#lang racket

(require (lib "unitsig.ss")) ;;<- that's what i added

(define SchemeEsq

  (unit/sig () ;; no exports

    (import mredˆ)

    ;; The repl editor class

    (define esq-text%

Then the problem becomes

unit/sig: signature not defined in: mredˆ  

Does anyone know what should I do？I don't know how to solve it. The f1 page doesn't work,

Unfortunately, that code that pre-dates the current Racket module
system, so it did not keep running for very long.

Enclosed is a somewhat modernized version of the code that should run
in recent (last 15-20 years?) Racket.

thanks for the reply!

I'm sorry I didn't specify the version and OS of the racket, it works very well, thank you.
