| Message-ID | <878qc8y96x.fsf@rpi3> |
Has anyone in the CP/M usenet community played with modern z80 homebrew builds with CP/M boot ROMS and flash memory. How do they work for you and all that mumbo jumbo. I've seen a few vids on youtube but haven't crossed any content of decent quality. I had been considering a rex/cpm chip for my Tandy 102 device but, have hesitated in doing so - mostly because the producer of the item can't/won't ship it into my country. But secondly, I prefer to use my Tandy 200 for most daily uses due to the larger screen. But, also, I'd prefer to dip my toes into CP/M on a device designed for it. And from what I've seen, CP/M is quite slow to use on the Tandy boxes. To date it isn't an OS I've ever used, but my extensive history with DOS should make the transition straight forward. It is becoming more intriguing as the days progress. I look forward to any discussion on the matter. Daniel sysop | air & wave bbs finger | calcmandan@bbs.erb.pw

There's also RunCPM that's a CP/M emulator that can run on most modern computers, if you aren't in to hardware.

I've considered a kaypro after watching 'tech tangents' youtube channel. I'm not fond of retro computer key configurations and I'm very fond of function keys. I have an interest in making a homebrew kit with LCD and modern keyboard and I'm day one of research. Daniel sysop | air & wave bbs finger | calcmandan@bbs.erb.pw

I have some software concepts I'd like to test. The devices like the kaypro and the TRS-80 models with cpm are compelling for me. I'd like to double my usage and use them as terminals too. I have a vps and a RPI that I use for various things. I also do a ton of BBSing. Ultimately, I'd like to build a homebrew machine physically modeled after a trs-80 data terminal/model 4p. So, a case that holds an LCD screen and a keyboard with a standard modern qwerty layout as well as the hardware. It is going to be a tall project.

I used an old radio case - speaker on the left, small door to access the knobs on the right. The speaker I replaced with a small VGA LCD display. Then I built an RC2014Zed and put it in under the door. The door area made it easy to hide things, including a USB/Serial cable on the aux port so that I could transfer files easily. Finally, I hooked up my own reset button and mounted it externally on the case. The end result is something that looked more like a short Kaypro than a TRS-80 4P, but it works nice.

It's an interesting experience. When you say 'modern Z80' - that doesn't really make a difference. CP/M specs state it should run on an 8080 - which means any Z80 should run the code. The tricky part is creating a BIOS for your particular hardware environment. Digital Research (who made CP/M) produced an 'Alteration Guide' to help users with this process. And I have a Gotek on one of my Osbornes. Very convenient. But I don't use them on all my machines. I prefer to keep the drives running. -J

For my build, I'll need to find a nice LCD panel no larger than 15 inches viewable for what I'm envisioning. I considered finding an older LCD panel but modern models use less power. A requirement is low power consumption and fanless operation. Already have the keyboard model identified from another project.

I should mention it was due to the popularity of the RC2014 that a decade ago I dusted off my CP/M Forth compiler and began developing it again.

The use of an emulator as a help tool for testing and getting acquainted with CP/M has been mentioned a few times in this thread. I like to tinker with Ronald Daleske's EMUZ80 RPI - Z80 / CP/M. A CP/M emulator on a Raspberry Pi. https://www.daleske.de/projekte/prog/11_EMUZ80_RPI/prog_EMUZ80_RPI_en.htm Eisenbahn On 2026-03-06 02:43, Daniel wrote: > John <john@somewhere> writes: > >> On 3/3/26 2:00 PM, Daniel wrote: >>> Has anyone in the CP/M usenet community played with modern z80 >> >> Well, instead of purchasing something, you can write your own CP/M >> emulator and put it in ROM.

I've been pondering getting into RC2014 lately, as part of my exploration of permacomputing. How do you plan to interface the LCD to the system? From what I've gathered, the RC2014 normally uses a serial terminal as its interface, so I'm guessing you'll need to somehow interface keyboard and LCD to the serial port? I'm thinking 'simple microcontroller that drives the LCD and reads keystrokes and acts as a serial terminal to the RC2014'. What are your thoughts? Cheers, Koen

The project is on the back burner while I finish a previous project that's mid-way. What I learn from this project will help with my rc2014 build. Of course, I need to get one first and dick around with it. There are so many add-on cards to the rig I still need to investigate. Is the rc2014 open source? I mean, can I get the plans and get a pcb manufactured or do I have to order it from the dude? It's a bit pricey.

Indeed. I just pulled the trigger and ordered a 'pro' kit, which comes with the backplane, cpu module, rom module (which includes the ROM code needed for CP/M), RAM module, RTC module and a CF card module. I got a few extra modules as well, such as a VGA interface module and wifi module, but I intend to hook up an LCD and keyboard to it, but haven't really thought that out yet. I'd like to keep it as simple as possible. And yeah, I've got plenty of projects to work on as well, we'll see when and how I get to it :) > Is the rc2014 open source? I mean, can I get the plans and get a pcb > manufactured or do I have to order it from the dude? It's a bit pricey. From what I can see, the schematics for all the modules are available as PDF files, but I haven't seen any CAD files. It's all very simple and straight-forward though, so not too much effort to create your own schematics in your CAD program of choice and create your own gerbers. The software is all open source though (although I guess CP/M itself is not). > What does permacomputing mean? Well, depends on who you ask I guess. There's a lot that goes into it, but let me summarise to say that it's about making computing more sustainable. It's a movement that's fed up with the tech industry's wasteful strategy of planned obsolence, but also a movement that considers that the global supply chain on which modern computing relies might one day go away. For me, the RC2014 and similar projects fit in because they use simple components and create systems that can be understood and maintained by an individual rather than requiring teams and teams of people across many huge companies to produce and maintain.

I did look up permacomputing in the meantime. For me, I want a device that will work the same the day I start using it than years later.

It depends on which backplane you get. The pro one fits 12 slots, but there's an 8- and 5-slot version available as well. >> For me, the RC2014 and similar projects fit in because they use >> simple components and create systems that can be understood and >> maintained by an individual rather than requiring teams and teams >> of people across many huge companies to produce and maintain. > > I did look up permacomputing in the meantime.

It's as if some people think completely redisning the UI of whatever every month or so makes for a great user experience. I'm getting tired of relearning everything each time I turn the machine on. I'm curious about the software offerings though, haven't looked into that much yet. Do you have any tips on where to look? > I look forward to exploring the cp/m world.

The whole noveau-BBS scene is something I also plan to get into at some point, but there's only so much time in a day. I'm quite looking forward to diving into CP/M myself, it's gonna be fun. I'm curious to see how far I can take it. The kit is now stuck in customs, but won't be long before it's here.

Just a small remark at the very end of the post, not about CP/M as such. (My first computer was a Kaypro with CP/M.) On Wed, 13 May 2026, Daniel wrote: > [trim] > [...] And there's a RC2014 BBS that > I'll poke around in too. I asked the sysop some questions but he replied > with 'read the fucking manual.' I guess some people don't like to have > conversation anymore. Yes, this seems to be a growing problem online. I am an elderly person and do not always think of some ways of doing things that are outside my experience, so I ask a question in an online forum. Often I get a response of RTFM or "Google is your friend" (even though I tend to use other search engines). It seems like the interpersonal touch has gone away for some people. Sad. -- Paul Bartlett
