Looking forwards to seeing you there Tom.

Concerning the clicking in NitrOS9 - two things I would try: 1) Before typing 'GShell', try typing 'keyclick off' first. Or 2), after it boots to the Shell, hit CLEAR to go to a different window (3 full screen windows are set up by default) and run GShell from there. Keyclick is on by default only in the /term window; the /w1 and /w2 that are also started on boot both have keyclick off by default. Hopefully that fixes the issue (unless it is MAME itself on the Pi as you were mentioning). Level 1 vs. Level 2: Level 1 is for 64K RAM machines (like the Coco 1,2 and the Dragon 64, all of which had versions of OS-9 Level 1). Level 2 is for systems with >64K of RAM and an MMU, so that is exclusively Coco 3 (well, there are versions for GIMIX machines and other "big iron" 6x09 systems, but those don't have GUI's). The menus getting screwed up could be a couple of things (accidentally loading a font overtop the system font, etc). Oh, since you are running on a PI with a nice clear screen, you could select the 80 column option from the VIEW menu to view a lot more icons at once. Feel free to ask any questions here or on the Coco Discord about NitrOS9!

FYI if you add status=progress at the end of the command you can get a real time progress rather than just waiting for an unknown amount of time.

how come some floppy images are just 12 kilobytes ?????in size i don’t quite understand this because most of them are either 200 k or 400 k yep

The AMX Mouse looks like a copy of the Genius Mouse GM-6 for PCs

going on the Saturday, Tom - hope to see you there !

Great video Tom, I’ve always liked that keyboard to type on for the buttons feel and sound.

I tried to get 3d Zicon working with Beeb Em but it just crashes out. I really want to try and get it working. AMX Desk was a nice bit of software. As was SuperArt. It would have been good if they had done a mode 2 version somehow! How on earth did they get 3d pool working like they did. Amazing!

I had the exact same AMX mouse that I used on my bbc master and with an interface board I could also use it with my z80 pcw to run stoppress a desktop publishing program. I loved my AMX mouse with the red buttons. I always thought the archenemies mouse was the same body with a different connector. But looking I realise while simulator they are different. Thank you for a wonderful video down memory lane.

waiting for my X1 to arrive. too bad not manyy youtubers covered this. but gonna be using a 4k touchscreen on it over hdmi+usb. hoping it'll cope enough to handle a web browser with a server in the back end.

Great stuff, Tom! I just got my Rio board going yesterday. Excited to get the SD card rolling tmro.

interesting video! RISCV has done quite some leaps the last couple of years.

Need to upgrade the berry to 4Gb ram and 32GB Emmc like the banana BPI-M4 Zero

Can I do this with just an Arduino uno 328pb???

wanted last few years just got pi 800 as used today its nice upgrade from my raspberry p4

Just bought one of these, the project potential is huge!

Sorry - I know this is an old video, but I have just followed it (along with the Diet Pi Docs) to install DietPi (I prefer visual learning). In the video you start the LXDE Desktop by entering sudo startx. How do you get the Desktop to auto boot?

With using a usb keyboard- will a usb keyboard with a number keypad work? ( ie will the numbers work? )

I can't wait for the amiga maxi

I have a slightly different problem. I actually want the PB version as I wanted to use one extra 16bit timer. To my surprise the board is recognized as ordinary Nano and programs without issues. However when I switch to MiniCore and PB version it looks like the bootloader is unable to connect to the board. Seems like this time the chinese manufacturer actually did put an effort to make it Nano compatible but made my life harder in the process. The problem is I cannot simply switch to Nano in Arduino IDE and upload hex compiled for PB as IDE is trying to compile it again and of course doesn't find some registers from PB. Edit: OK, I have verified that it has a botloader that with "Old bootlader" setting in IDE allows to program it as a normal Nano. And in AVRDude it indeed gives a signature of ATMega328P not ATMega328PB. I've used the "Export Compiled Binary" option in Arduino IDE to get the hex file and used AVRDude manually. It worked as a charm - I can run program written for PB variant and loaded with the old Nano bootloader. Since the last time I've used AVRDude was probably 15 years ago if not more I've took the execution command with all the parameters from Arduino IDE console when it was set as normal Nano and used it as a hint.

Yeah, I tried this the other day with a new flash on my Pi400 and I wasn't impressed. Wifi connected and I got an IP address, but that was about it. The black border (overscan) was present and I don't see why it should be given that 5.28 didn't have this issue. I had the same issue on my PI 4. Sad really as I was hoping for a beautiful experience out of the box. New users won't go passed their first boot, call it a day and repurpose their SD card.

Interested that there will be a 2354 version of the chip with 2MB non volatile internal flash according to the data sheet. That chip with onboard WiFi is going to be pretty cool.

Didn’t have to reboot to get the mouse to work!

Great video! Hint: you don't have to keep saying both: It's officially "RISC-five. not "V".

So... Who is this kind of operating system for in 2024? What is the actual usecase for it other than just being another niche OS?

Cool gadget from M5Stack! Can you take a look at MSX0 too?

I'm dithering on getting one of these. I've a couple of Pico (1) projects I never quite finished. I'm interested in the RISC V, but I think I might hold out until they release the 'W' version of the 2 later in the year.

Probably the next announcement will be a new Zero board, with more memory or an updated CPU, or both...

I remember when I got GEOS with my C128 and it was amazing, but then ultimately I went back to playing Uridium in C64 mode after a few minutes and didn't load it again.

The 26 pin connector is compatible with the Raspberry 1.

Nice video. Thanks man. Will you be covering SymbOS for Amstrad and MSX computers in this series?

Interesting ! Do you have a version on the Arc software that used a SHAKUHACHI flute as a bong? I only want the bong :-) It was the start up of my first Arc, the first HiFi sound that I ever heard from a computer. Magic. I looked on in wonder at it ..

It is really weird that the Arduino console calls it "Both NL & CR" instead of "CRLF". Idk why they would diverge from the standard ASCII notation for the characters.

WARNING! The ATmega328PB is NOT a drop in replacement for the ATmega328P. TLDNR See Atmel Technical Note AT15007 "Differences between ATmega328P and ATmega328PB" for more information. Of particular concern is that two of the pins that are used for VCC and GND on the ATmega328P are now I/O pins on the ATmega328PB. Pin 3 is GND on the ATmega328P but is PE0/SDA1/ICP4/ACO/PTCXY on the ATmega328PB. While pin 6 is VCC on the ATmega328P but is PE1/SCL1/T4/PTCXY on the ATmega328PB. If the PCB is made as per the original Nano spec for an ATmega328P then pins 3 and 6 will be connected to the GND and VCC rails respectively. If you use an ATmega328PB firmware and enable either of these pins as output things are not going to end well. Pins 19 and 22 have additional functionality on the ATmega328PB but at least these pins are taken out to the ADC6 and ADC7 pins on the Nano. Pin 19 on the ATmega328PB is PE2/ADC6/PTCY/ICP3/SS1 while pin 22 is PE3/ADC7/PTCY/T3/MOSI1. The technical note does, however, state that the ATmega328PB is fully software compatible with the ATmega328P so it "should" be possible to upload a Nano firmware to this device and use it as an ATmega328P without the additional features of the ATmega328PB. This assumes that there are no bugs in the firmware which alter any unused/reserved bits in the ATmega328P registers that are used by the ATmega328PB. Such bugs would go unnoticed on an ATmega328P but may cause issues when executed on an ATmega328PB. This caveat also applies to any libraries used. As others have commented the old Nano bootloader appears to work but the new one does not, this may be the reason why. The Arduino IDE will not program the Nano bootloader into the ATmega328PB because it has a different signature to the ATmega328P and AVRDude checks this signature before uploading anything. It is, however, possible to upload the firmware from the command line using AVRDude with the -F switch. The -F switch (note upper case) forces AVRDude to ignore the signature bytes and upload the firmware. The ATmega328PB also has additional fuse bits and uses a low power oscillator, the rail to rail oscillator option is no longer present. This low power oscillator has a clock failure detection (CFD) circuit and fuse which force the ATmega328PB to revert to an internal 1MHz Calibrated RC Oscillator when it detects missing pulses. This clock failure detection can occur due to poorly routed boards that would not be a problem with a rail to rail oscillator. CFD can only be recovered by power cycling or a hard reset. This can result communication issues and other errant behaviour. caveat emptor

The good thing is that the 328PB has much more peripherals compared to the 328P, you've got 5 timers, 2 UARTs... So we can say that we were not scammed, quite the opposite :'D And the other thing is that with my nano board I noticed the TX pin always on when I first plug the board, but I was able to reprogram it by selecting the ATMEGA328P old bootloader... Cheers

Definitely a piece of tech that's on my wishlist.

Cool little system. But I don’t see any use case for myself. Could be mounted on a little robot or so. To drive with? 🤔

Had to buy one on the m5 website as pi hut don’t ship anything with lipo batteries to Scotland! So I’ll be a couple of weeks before I get mine! I’ve had this before with pi hut and it’s really annoying!

They are nice , I have a couple, the keys hurt my fingers though ...

cool device. and i love the excellent flag behind you.

I got some of these a couple of days ago and finally got them working fully. Initially using "old bootloader" worked. Various reports said the old bootloader has bugs so I wanted to update it. I tried usbasp but that failed because it said it was the wrong chip signature. I tried adding a 328pb board but the implementation I tried failed with a strange avrdude error message when I tried to write the bootloader. After readiing a few forums I found out you *can* burn the 328p bootloader by changing the chip spec for the 328pb. That can be done by manually entering the bootloader upload commands it uses with avrdude. When you do that the bootloader will lie to the IDE and it will behave pretty much like a normal 328p thereafter. The two chips are apparenly so similar that will work: but you can't use any new features in the 328pb. After finding that solution I found the bug in the other board implementation and now everything works fine.

I made it work with the Vonets router, but it was tricky. I think I had to edit some DHCP script. TLDR: it needs the wifi driver ported properly

I wonder how DietPi would do in comparison.

Hey, as a newly to the retro World, I fully understand. Work comes first. I do enjoy the discussion. In my own interests, I am an advocate of projects, over long-term schedules. Can be easier to manage. Hence like another commenter, I'd love to see more on the BBC Micro, or BASIC - or something I could follow and try!

Can you do more shows about the BBC Micro? I love your content and I just bought a BBC micro!

The book is $400 on eBay!

You deserve a lot of subscribers

It's been a while since I used Atari Basic, but I think Control-C will break the program from running.

First comment!

I am using rpi zero w itworks beyond wonderfull. everything works.
