Zwischen dem Eierbemalen („Ostern steht vor der Tür“ 🙂 ) haben wir heute (mit KKRYS) das Diagramm und Design der Schnittstelle zum AD724-Chip verbessert. Ich habe den PAL-Träger-Duplizierer und einige passive Bauelemente entfernt und eine Softstart-Schaltung für den Konverter hinzugefügt, die auch a...

Hi Janko, VGA1 ist für den HDMI-Grabber vorgesehen, da an Pin 6 ein CVBS4HDMI-Signal anliegt. VGA2 auf Pin 6 Massesignal. Der SC1224-Monitor sollte an beiden VGA-Ausgängen gleich gut funktionieren, da an beiden die gleichen H- und V-Signale verfügbar sind... Den Monitor schließe ich an VGA2 an und d...

I agree Wolfram. We need to correlate our steps :-) Yesterday I try to place a few extension together (someones only printed because I'm waiting for PCBs) and it looks like this: image.jpg Atari 800XL is little problematic because we have not so much space between original PCB and keyboard. Let's tr...

Ansatz ZWEIT Parallel zu meiner Arbeit mit AD724 habe ich beschlossen, ein weiteres sehr interessantes System zu testen – den CXA1645 von Sony, der einst in Viera-Fernsehern verbaut war. Die Anpassung des Systems ist deutlich komplizierter, aber die ersten Tests zeigen, dass es sich gelohnt hat. Ic...

I tried to convert ATR to CAR using @gienekp software called atr2car which is using to converts full disc games to MAXFLASH format cartridge. It doesn't work with XDOS (despite jump translation option used). If anyone is interesting how it works: http://dcart.pl/ Could you please share XEX/COM file ...

pancio

Hi,

Is possible to have XDOS installed on cartridge? I need to XDOS as alternative to SDX on MIDIcar device and other hardware staff (because of speed, flexibility, monitor included, etc.)

Ich möchte Sie darüber informieren, dass die Funktionstests abgeschlossen sind und SavoNARA: VBXE2VGA/SVIDEO einsatzbereit ist. vbxe2vga_v1.0.2.png Hauptmerkmale: - Erzeugung eines S-Video-Signals in sehr guter Qualität – Anschlussmöglichkeit an DIN-5-Buchse (Original im Atari) oder HDMI-Konverter. ...

Ich habe in letzter Zeit darüber nachgedacht, wie ich das Bild von VBXE auf HDMI übertragen kann. Das Problem ist, dass die fehlende separate H/V-Synchronisierung am VBXE-Ausgang die Anzahl verfügbarer Geräte, die RGB-Bilder anzeigen können, erheblich einschränkt – im Grunde sind es ältere Fernsehem...

I'm still interested in!

I'm interested... if you have one more :-)

Will send PM.

If it possible I'm interested to participate as well.

As you expected :-)

Two different verison, first with bigger holes, second for ZIF40 socket.

When you will do 20 pieces... you will came The Master of Soldering - it takes about 30 mins :-)

Hi, Vielen Dank für Ihre netten Worte :-) und gleichzeitig entschuldige ich mich für die zu dynamische Entwicklung von UGV2-FF/GF – es kann Verwirrung und Bestürzung hervorrufen, aber es besteht kein Grund zur Sorge – alle Versionen sind miteinander kompatibel und unterscheiden sich normalerweise in...

I sent PM.

Just give HIGH on input.. will be good :-)

pancio

It seems that I have a different revision of the board. It is also version 2.6 but on your photo I can't see the capacitor C8 22p. In the schematic you write the component is optional. But should it be assembled or not? Since I have not yet programmed a CH32V003, I wanted to start without this comp...

pancio

I'll do it when find a while :-)

Normally, I soldered thin wires directly to pads and connect to oscilloscope's probes. But it's good idea to have dev-board like you shown for futures projects and modifications :-)

BR,

Just tell me if you want to have one piece as reference - I'll sent it immediately :-) During assembly I've one accident with 47u capacitor: after 2 minutes under load it has short circuit on power - probably was degraded during soldering process. I can imagine it's probably possible frequently. I k...

Hi, I'm sorry... What you means blue screen? Is it screen on your TV/monitor when you have no signal? Check clock on FOUT/74HCT175 pin 9 - shall be ~7MHz or 14MHz - depend on ICS501 S1&S0 configuration. Have you oscilloscope? Check signal on 1 pin of FMS6400 - it's VIDEO with SYNC. I know that i...

Ich werde noch mehr hinzufügen.
Es gibt eine weitere Version von UGV2-GF – sie enthält ein zusätzliches Modul, den sogenannten GTIA Fixer. Es verbessert die Qualität des Videosignals und beseitigt den GTIA-Defekt Typ 1.

Trust me... you will be very helpfully :-)

Just for fun.. first part of UGV2 assembly process:

Marcin shared STL files so it's not a problem to have one :-) as well as enclosure to 1090.

Wow... I need to spend a week to find this kind of adapter in the drawers :D . Instead of this I'm using cheaper version:

Programming header is not necessary. All process takes not more than 1s, so you may just only touch header pads during upload firmware. I'm using this method from v2.6 :-)

Hi,

I'm not sure... but as I heard there is no place for additional piggy board inside A800. I haven't it to check. Maybe it's time to make something like SCCC2? :-)

I'm wondering that HOKEY is not FPGA based solution but using micro-controller and software (P)OKEY implementation. A few months ago I decided to take off heat sink and I saw IC like tiny CH32V103 or STM32F103 with reduced 2 rows SOIC pins. Will check my shelfs and make soem photos. These are my con...

. I have now taken a closer look at the circuit diagram and the component list and have two more questions. Why is there a 0 Ohm (R8) resistor? The two capacitors C1 and C9 are shown polarized on the circuit diagram. Can I also use simple unpolarized MLCC capacitors or do they have to be tantalum c...

pancio

Fantastic. Thank you very much. You are really fast and develop faster than I can read. :D Should I wait with the assembly of the board ... Will there be more changes? Nope, v2.6 is really good tested and working perfectly. Version 2.9 has added optional capacitor on Fout line (you may add it if ne...

I attached PDF and BOM to previously post. Yesterday I sent to production new boards v2.9 which is little bit smaller.. to fit Atari 1200XL with UGV2. There was not possible with existing v2.6: a1200UGV2_placement.png So the new one PCB shall be ok: UGV2-FFv2.9.png I'll update you after tests. Of co...

Hi,

Programming is easy, just use CH32V003fun from github: https://github.com/cnlohr/ch32v003fun
If you want we may set short session in order to explain how to compile and flash image.

I'll attach PDF to my web page - as well as I may add it here!

I am very impressed with the image quality! I would like to make the board myself. Can I get the Gerber and BOM from you? Are the smaller SMD components of type 603 or 805? @pancio: What do I need to program the MCU-CH32V003? I only have an XGecu T48 [TL866-3G] . Was benötigt man um den MCU-CH32V00...

Hi UGV2 Freaks :-) I built and tested UGV2-FF v2.6 with very good results. Changes from 2.1 to 2.6 are: - values of resistors were changed to fit better luminance gradient, - MOSFETs were dropped and replaced by quick smidth's buffers (saved some PCB area), - LED diode was dropped, - added SELECT fe...

pancio

Thank you for your interest. I usually order PCBs from JLCPCB - cheap, fast and very good quality. So in my opinion is best option. I encourage you to assemble it yourself, but if you don't feel up to doing it yourself, I can assemble a few. I can also send it in bulk to avoid multiple shipping cost...
