@@MeinElektronikHobby ja kann man!

I would, be unfortunately I am currently out of PCBs and parts... btw, it's super easy to order Gerbers! Just go to JLCPCB.com and hit the upload button. Gerbers are on the Github: github.com/lambdamikel/picoram6116/blob/main/gerbers/PicoRAM6116-Gerbers.zip If you still don't want to try making your own, I can help, but given that I have to order parts as well (-> shipping costs) plus approx. 30 USD shipping from California, it's going to be a bit more pricey (say, 70 USD, that would include shipping). If you are not comfortable soldering, that's another good reason of course. Else, it's really quite straight-forward to assemble. Happy to help either way, LMK,

@@michaelwessel4953 thanks for your quick reply. TBH - I’d be fine for you to supply a built unit. Not clear if you can send me PM for us to firm up next steps but look forward to hearing back soon.

... I think I should have an M3 / 4 version available as well soon :-)

Absolutely! I have a simple MIDI IN / MIDI OUT & S2 MIDI playback recorder - just the raw data. I've been thinking about making a MIDI Tracker. Basically, like Sound Tracker, 4 to 16 Tracks, but for MIDI. Input is either via MIDI DIN, or from the keyboard. Playback via MIDI OUT and S2. It'll take a while to develop this software, but I am highly motivated. After all, implementing a simple MIDI tracker isn't that difficult at all.

@@michaelwessel4953 WOW. This is incredible. I’m not a programmer but would gladly buy something like this for my model 3. How do I stay in the loop on this? Is there a mailing list? Thanks!

@thishandleisalreadytaken66 thanks for your interest and kind words! I'll keep posting video updates on this channel. The M3 version will be out in 2 months or so.

@@michaelwessel4953 That’s amazing! I’ve subscribed and look forward to updates. Keep up the great work Michael!

@@cathrynm yepp, that's it - the true sound of the 80s!

Dankeschön, ich freue mich auch immer und über Deine Videos! Na, irgendwie sind das gefühlt immer weniger Views und immer weniger Likes. Wenn ich mir die Kurven so ansehen (Views), dann ist auch ganz klar, dass UA-cam "algorithmisch diskriminiert". Was die Kriterien für den Algorithmus sind, weiß ich nicht. Ich werde nächstes Jahr deutlich weniger auf YT machen - ich habe da viel zu viel Zeit investiert dieses Jahr. Ich werde meine Projekte eher nur noch auf Github stellen, das ist etwas "ruhiger" und "weniger aufgeregt". Hackaday bringt auch immer weniger Spaß...

Yeah I guess the utility bill would make running the real machine a bit prohibitive - btw, they also had the Cray 1A from the DKRZ in Hamburg there! Imagine my surprise when one Hamburger met the other 😀

It has nothing to do with the resistors. Even if you replace these with 0 Ohm networks, these chips aren't able to drive blue LEDs. I tried - that's why I put in a socket for the resistor network in the first place ;) I tried this first thing (and I think I also mentioned that in the video?) - don't you think I would have done this first thing before designing an "active" PCB with the 74LS244? ;-) So no, just playing with the resistor values doesn't do it.

PS "Schematics" and Gerbers are here (well, I didn't put a lot of effort in the schematics, but it gives an idea). hackaday.io/project/183618-exploring-the-microprofessor/log/229422-the-worlds-first-mpf-1-with-a-blue-led-display

PS2 The resistor array I currently have installed is actually a 0 Ohms one! You can see from the video that this doesn't do it.

@@michaelwessel4953 Sorry, I'm not following. Your resistor network (RN1 on your schematic) is on the pull down (emitter) side of the 75491 output transistors. I was talking about the pull up (collector) resistors on the original PCB.

@Brian_Of_Melbourne forum.classic-computing.de/forum/index.php?thread/32631-bastelhilfe-gesucht-blaue-7segment-anzeigen-im-microprofessor-mpf-1/ Know that R5 is 0 Ohms already in the original design and on the board, forum.classic-computing.de/forum/index.php?thread/32631-bastelhilfe-gesucht-blaue-7segment-anzeigen-im-microprofessor-mpf-1/ and that I replaced RA4 with a 0 Ohm network as well. To no avail. So I think what you are suggesting doesn't work, and that's why I had to add the 24LS244 as an LED driver. No matter how you tune the resistors, the original circuit is not able to bring the voltages above 2.3 V or so. Insufficient for blue LEDs..

LOL... that was funny. Thank you.

@MattFixesStuff yeah please remove the battery and replace the belt. The CE-125 will thank you with many more years of service.

@@michaelwessel4953 Hey I took out the battery and replaced the belt. Only the main belt though. it seems to run normal now. But I still cant read from the tape (stuck at "busy"). Just writing seems to work. Not sure if the tape is dead or the "read head". I'm just gonna sell it anyways. But its a really fun device. I wrote some basic programmes and they exexcuted fine. If I was born 20 years earlier I could see myself having a blast with that as a kid :D

@@MattFixesStuff they are neat little machines! Of limited utility these days, but back in the day, they were magic. I never had one as a kid, but a friend of mine had a Sharp PC-1500. I now have a rather large collection of Sharp pocket computers, including the CE-1500(a). Hmm, yeah, fixing them can be challenging... well, maybe get yourself a broken CE-125 from eBay and get a new tape recorder and/or mainboard from there. That's what I do... most of them are "untested", and if you are lucky, you can get one for as cheap as 35 $ or so. Good luck!

@@michaelwessel4953 Yeah I would just try another cassette and changing the read head. But I have 7 nintendo switches that I need to fix curretnly. So I'll just sell this to someone who will treat it nicely. Its in very good condition and i'm glad I got to play with it :) Still a sweet calculator for flea markets or something though :D. You could write like a little programme to make invoices for example. It's just so cool. maybe i'll sleep over it before I sell it.

Evtl. haben Sie einen Bezug zu Malchin? Mein Vater ist leider letztes Jahr von uns gegangen. mfG.

@@michaelwessel4953 das habe ich mitbekommen (mein Beileid dafür) , und ich habe nicht nur einen Bezug zu Malchin, ich bin auch in diesem Video, deswegen meinte ich auch das mir dieses Video vorgeschlagen wird ist echt Zufall

@@Black_DeathKnight sind Sie eines der "Kinder" von damals? 9 Jahre ist das her. Welche(r) sind sie denn :-)

@@michaelwessel4953 oranges Shirt relativ oft ganz vorne 😅

Excellent! Enjoy!

So ist es! Das ging damals als "Anwendungsprogramme" durch 😀

@@michaelwessel4953 ... stimmt. Ich hatte die Programme fpr einen Biorhythmus für den C64 im Programm. Das war so ein billiger Schnellschuss, wurde aber gekauft.

Ah! That makes a lot of sense now: "The Magnavox Odyssey²'s "The Voice" attachment uses the SP0256-019. This variant included the same allophones as the SP0256-AL2 (but an external ROM IC is required for the allophones), along with some Odyssey²-specific game phrases." THANK YOU!

@@michaelwessel4953 These SP0256 speech chips were part of the soundtrack of my youth. I will always have a soft spot in my heart for them. Thank you for sharing your setup! 👍

@@BinaryCaves not without modifying the Gerbers... it's not impossible to get these flat mylar foil cables with the right spacing, but requires certainly more work than what I did.

@@michaelwessel4953 Thanks for the reply! I have several broken ones and will give it a go :)

Ging mir auch so - 1985 hatte ich einen Schneider CPC 464 :-) Den MC6400 habe ich erst 2020 bekommen.

Good old days... glad you are still enjoying it! Yes, it never got the love it deserved from the broader retro community, and it has its shortcoming (sprites, ...). But what a rock-solid, stable, versatile (= well rounded!) and mature machine, especially for programming and productivity back in the days: 80 columns, CP/M, the Locomotive BASIC! And some games weren't that bad either (Sorcery, Fruity Frank, ...)! It's amazing to see what people achieve nowadays with this hardware. Sadly, less and less is happening, but we will always love the CPC. Thanks for chiming in, keep the CPC and your love for it alive! Cheers

@@MeinElektronikHobby es kommt sehr auf die Qualität der Vorlage an. Der UPC auf der Box scannt doch hervorragend.

I wish I knew! I got it for a few bucks a while ago from eBay.

@@gregskuza7166 bitchin100.com

Interesting idea. I guess using a Commodore drive would indeed have been feasible, given that both are basically serial "intelligent" devices. Still, a lot of low-level protocol stuff to implement. Thanks for sharing!

@@michaelwessel4953 I saw a video once on how to do this but involved building an interface due to the different voltages used by both machines.

Yes, thank you for making it - it's a really fun game! That'll be useful, it's a bit bright on the color screen - I also really need to get a better camera at some point.

Interessant, das kann ich mir gut vorstellen - wir hatten 1985 noch CBM-Maschinen im Computerraum des Gymnasiums (CBM 4000er und 8000er - sogar einige CBM-II!) Sogar mit mehreren der dicken Doppelfloppylaufwerken. Mit denen habe ich damals die Computer-AG geleitet. Erst 1987 oder so wurden die dann durch Commodore PC-10 ersetzt - Informatikunterricht gab es für mich erst in der 11. Klasse (1988 oder so). Wir haben dann auf dem PC-10 Turbo Pascal gemacht.

Vom Printer-Kit habe ich noch nichts gehört! Klingt spanned. Kommt wohl auf einen Versuch drauf an? Die Printer sind sehr selten.

Na das freut mich - herzlichen Glückwunsch! Ein guter Kauf!
