Last Meeting (May 21th)

Our last meeting was May 21st at the regular location (Christ the Lord Church)

Thanks to Jeff Stokes on a very detailed and wonderful job of relaying the insides of all things CP/M.   When he has a complete set of instructions ready to post, we will included a link here.

Overall, he covered how to get software/files onto your CP/M machine.

He demonstrated an easier (compared to making your own floppies) way to get software/files onto your real CP/M machine from your PC using a NULL Modem cable, a CP/M Terminal program like MODEM901.COM or IMP.COM, CP/M Emulators and serial server software running on Windows/Linux/Raspberry Pi. He showed that you can also logon to BBSs on the internet using this setup.

One of the details that he pointed out is that you definitely need to know what kind of serial port it has.  Does it have a UART chip or is it CP/M SIO software driven?  This information is needed in order to assemble/link a working terminal program for it.

CP/M software needs to be re-compiled in a lot of instances to run on the various machines.  Jeff demonstrated  two main ways  to do this.

 If you ask, he can provide copies of the SW he used (maybe at our next meeting if you weren’t able to get it at this meeting.)
