Contiki OS / ZS DOS / MICROBEE MULTI-BOOT

I asked Claude what OS it would like to build for Microbee. At first it looked at SymbOS but stated memory issues.

Then it told me about the NEC 6001 microcomputer from Japan

and the Contiki OS port which features a process list, command shell, calculator, text editor, and a RAM filesystem as well as internet connectivity, telnet, email etc.

I said build away and it did. So now I have working internet @ 9600. An email client is a definite possibility if I lose the calculator and text editor.

As Someone has oft mentioned, the Microbee is a true chameleon.

my apologies to someone, his word is doppelganger not chameleon.

So https is working, and my brain was in overdrive. So I thought, so much unused space on the boot image.

Introducing Leeloo Dallas mul-ti-pass Microbee Multi-boot.

Using resources from gaby.de I now have a bootable zsDOS too. I am optimising zcpm video display speed and TPA atm.

I have room for one more OS (Contiki only needs 2-3mb) - any suggestions?
