Temporarily, you can comment out line 232 in config.h (turns off printer). It appears the sketch is right at the limit of the size, and depending on how I compile it, it's too big. I'll see if I can trim a bit (it's only over by 75 bytes when it compiles too big. I was able to compile it with all functions on, but it looks like it depends on what has been cached. Or, you can use avrdude to load in the precompiled files in the m328-arduino directory, which are compiled using the native makefile system, and are smaller (The Arduino IDE compilation is not as compact, 29K versus 32K). Jim

If someone is willing to pop open the module, take pics, and measure (and be reayd to measure or take a few more pics), I'm happy to lay out a replacement PCB for the image. Jim

Hehe

Why did the earlier boards become FujiNet obsolete?

Version 0.9.3.3 released: https://github.com/go4retro/HEXTIr/releases/tag/v0.9.3.3 Some bug fixes (access beyond an EOF) and the unlink open file command implemented. Peter Engels should take all credit. I just merged in his changes.

Ultimate II+ is similar. Tougher to do a FujiNet for CBM, as the serial, drive, and otehr stuff are on different points, not the SIO port.

Yay! If you can email me the Fritzing fzz file, I will update the repo.

Hmm, nothing under the email address I sent my note to. Let me send another note out. JIm

I bought both kinds. We'll see. Jim

I understand, but I thought someone else figured out a solution. If not,I'm not sure how I will be able to address the issue. These long IDC 2x4 connectors are nothing I have seen available anywhere. I typically use a regular IDC cable and a 2x4 arduino header/socket combo: Like the 2x4 one in this set: https://www.ebay.com/itm/Arduino-MEGA-Stackable-Female-Header-Pin-Shield-Kit-5x8-1x10-1x-2x3-1x-2x18/121561736528?hash=item1c4da4e550:g:0T8AAOSwPhdU0e48 Jim

OK, anyone have an enclosure I should try to fit? I'm looking at Hammond units, but nothing is reaching out. The current PCB is 38.10x81.92mm, but I can finesse it a bit for a good case. If I went a bit wider, I could put the DockBus and HexBus connectors in parallel on the back, with a Mini USB for power and the switch int eh back. Let me know if anything looks interesting. Jim

Hmmm, I thought someone already offered the cables? Jim

Sure, email sent. For others, PM or (better still), fire off a note via the contact form at go4retro.com and I'll email back, and then we can converse via email. The above says the bus is not correct, so that narrows things down quite a bit. JIm

I'd like a little more clarity on your question, but I'll try to answer: The DockBus and Hexbus connectors are completely different, but they are electrically compatible. If you install both connectors (1x10 under the board, 2 2x4 connectors on top), you will not be able to plug into both DockBus and HexBus at the same time (by design, as I don't think that is supported), but you can use either a DockBus cable or a HexBus cable to connect to the unit. Jim

I am prepping a new PCB run. Any suggestions before I move forward (mounting holes, etc.?) The unit has dual hexbus ports and a dockbus port, as well as power and activity leds. It does include a real time clock and headers for the 2 serial ports.

Well, I tested it, and it works here (I did get a few #39 errors early, but can't seem to reproduce). Is it possible to send me some pics of you wiring of the dockbus port and cbaling to the ti-74? I tested on my TI74 using my hexbus to dockbus converter, but I can't get it to fail here. I did find a bug in the PRN subsystem, but I don't think it makes a difference here. I also used the Arduino 1.8.13 IDE, but I doubt that would be an issue. Something else you (and others) can try. At the top of the config.h file, there's: //#define CONFIG_UART_DEBUG Given the additional code space needed for debug, you'll have to comment out #define INCLUDE_SERIAL, #define INCLUDE_CLOCK, or #define INCLUDE_PRINTER to get a small enough code file to upload to the Arduino. Uncomment that and fire up the internal serial monitor in the Arduino IDE, and after flashing the app (it should be set to 115200bps, but change if needed), it should greet you with "HEXTIR ... 0.9.3.1" When you execute a HEX command, debug should show up on the console. THat debug data is helpful as well. Jim

Sorry, I have to remember to quit answer these later in the evening (and yet here I am doing it again). Line 222 (or around there, my local copy has some newer changes): #define INCLUDE_CLOCK You need to comment that line out to: //#define INCLUDE_CLOCK Make sure it's the one under the : #elif CONFIG_HARDWARE_VARIANT == 3 /* ---------- Hardware configuration: Arduino with low power sleep---------- */ text. See if that helps. If not, let me know, and I have one of those boards, I can quickly set up the test here.

Oh, clock functions might have an issue, since this has no clock. So, keep that in mind. If it does cause issues, we can turn the clock function off in config.h (comment CONFIG_CLOCK=1 out).

Yes, though you also need to tie pin 8 and 9 to ground (since this uSD board does not bring out WP or Card Detect.) Should work fine with the stock Arduino build. Let me know if there are any issues, as I have the same little board here and I can wire it up and test it if needed. Jim

There's a IAC parser in tcpser: https://github.com/go4retro/tcpser nvt.c

I can't speak to Meinhard's application, but HEXTIr has been tested against the cc-40 and the TI-74 by Peter Engels (or TIIF fame) and all tests have passed. He uses it with his TI-74. Jim

Wow! I buy DIN6 all the time for projects, and they used to be $.50-$.90/unit. Not sure what is going on with the $3.XX pricing. But, if there's a need, I buy them in bulk now for cheaper prices. Still, eBay has you covered: https://www.ebay.com/itm/Circular-DIN-Jacks-Right-Angle-PC-Board-Mount-6-Position-NEW-Qty-5/200766611764?hash=item2ebe9f6134:g:G4UAAOxye5BREkvs And, there's a footprint in EAGLE which can be easily converted. Jim

It's not hard gold, but I've had units in production and use for years with ENIG and no issues. If it does wear away, there's copper below it, which might get a bit of patina on it, but nothing a quick run with an eraser or something won't fix. Unless the item is a collector unit, I am not sure the extra cost of hard gold on the fingers is worth the expense. On the other hand, depending on PCB house, hard gold on the fingers may not cost that much, so if folks care a lot, a batch of 100 PCBs might only be only $.50/PCB more for hard gold. For my money, though, I don't think it's justified. Jim

PAL and NTSC use the same power supply outputs, so just use a NTSC PSU. Unlike the 64, I don't believe the 50/60 Hz issue plays a part. Jim

I agree with @arcadeshopper, merges tend to be a bear, unless they are automatic, at least for me. That said, it's unclear if the poll is: 1) how many people use online version control in general or 2) How many people use github.com versus gitlab, bitbucket, or other options It's probably not: 🙂 3) How many people use online source control as opposed to a offline set of repos or 4)How many people use source control at all As for me, I have used source management for many years, standing up SVN long ago on the main home Linux server and periodically publishing tarballs/ZIP archives of my working files. But, since I release almost all of my projects as open source anyway, tools like github are attractive as they automate some of these things and make it easier to be transparent about project efforts. For some projects that I don't share publicly, I use bitbucket, mainly because at the time they allowed private repos for a lower cost.
