CP/M Boot Menu?

Is it possible to have a simple menu to appear once CP/M has booted? I'd like to be able to select Newword, SuperCalc, and some games off it. In MSDOS I'd use a batch file, but there's nothing similar in CP/M AFAIK. Any ideas?

Thanks.

Re: Building a replacement MTX PSU

Oh, BTW, my last name isn't quite spelled correctly. The R & E need to be transposed so it reads WYER. Thanks. :D

Re: Building a replacement MTX PSU

But still with time to play :-) So I can see! You have been a busy bee. Now to find somewhere to print it for a decent price. The web page looks great too, although it might be worth mentioning that fuse F3 is a slow blow type for the 110v model. It's listed as such in the BoM, but it may be missed...

Re: Building a replacement MTX PSU

Attached is the BoM for parts from US suppliers.

@Mark, do you want to merge it with yours, or keep it separate? Best to give it the once over as well.

Re: Building a replacement MTX PSU

Thanks a lot for the additional photos, as I said, your example is looking really good, it may be your first DIY electronics project, but you've obviously done other projects before, the build is excellent. You're too kind! I've been busy with my TI-99/4a and it's Peripheral Expansion Box (PEB) ove...
