Implementing Kermit was one of the first things that you did back in the 70's when I was involved in this stuff. Great memories!

Totally I am currently working on and old bunch of 8088 gear i found at a tip. Step by step it is growing into a fun beast. This is great stuff

Awesome stuff, watching all these youtube videos on the Z80 and CP/M really have me wanting to build something up myself now. :)

great video as always have just built an RC2014 full monty kit over xmas and have had great fun with it and basic. there is now a Cp/m add on kit from RC2014 with flashcard module and new 64K ram and Rom boards available and have just received and started building that to add to my RC2014 system to play with so thanks for the Cp/m video

Thanks much. You've provided a path for me to get my S-100 system to a CP/M functional state. Very nice.

I don't recall exactly which BASIC this was for, but I remember typing SYSTEM to exit and return to the operating system environment.

Super awesome!

Thank you Sir! for great videos. I like them a lot :) So i want ask for master what is cheap eprom programmer and what is common logic chips caps and resistors you using your projects. so i can order bunch of them

The bank selection can also be called MMU. ;-)

Hmm You mentioned overflowing the buffers when copy pastin laege programs,, I'm shore you have tried eunning the serial connection at a sliver rate, what was the result, still overflow, or was that the one tjing you forgot to tes. It is rather easy to forget the simple things

hi great work! is the bank switching strictly necessary? im curious and just about to experiment i was thinking of using just a single sram chip with no rom or memory glue logic and have an arduino with bus expanders hold the z80 in busreq state while it fills the sram from an sd card then let the z80 loose on the sram chip giving a flexible selectable rom system... i have the basic nascom system running as such atm, and would like to take things to cpm but im not sure if i could load the bios into the lower portion of sram and let it do its thing on the upper parts of memory then instead of switch the rom out just let cpm overwrite the bios? hope that makes sense

I'm interested in the process of creating your CP/M installation.

what makes this difrent than your blog post 15 bank switcher.blog 15 looks like try invent wheel and will this board work on rc2014 oh yes work,but will this work on your samples or you have made major changes and i should build board from blog 15. just want get started z80 assebler stuff.

You could have edited out the part where we're waiting for stat.com to download :)

hahahaha woops and i just erased it. hahahahaha

Why would you bother making a micro computer that will run CP-M? CP-M was never meant to be an operating system. It was a minimalistic OS that was used, by engineering professionals, to create fully working operating systems, it was only partially completed and was in what we today call a pre-beta stage operating system. There were so very many bugs and errors that the CP-M system had in it that is was the reason that many model 3 and model 2 Radio Shack systems came into my service center in the 80's, of which I was the service center manager, like BDOS errors which users insisted were computer errors but were only bugs in CP-M coming to light. I would have to run a full diagnostic on these systems, including burn in test on the RAM, only to have no errors found and only resulting in the customer having to pay a service charge to not have a problem found with the system. If anyone was to build a 'system' build one that will run a 'tried and tested' full operating system not an 'engineering' trial system
