    Don't bother desoldering anything. Just add the 36 pin extension connector to the empty holes.

    Part of the problem with any of these modes is sync polarity. In NTSC and PAL, both the H and V sync are negative polarity. When you XOR them, they produce a complementary product where you get a...

    Thanks for the investment. I know the tooling can't be cheap. And the community will certainly appreciate it!

    To bad I'm after the opposite - D-23F and D-23M with RA PTH tails for PCB mounting.

    You don't have to go through all that work in your video. If all the IDC connectors are oriented on the same side of the cable with the tab in the same common direction, they will all tap the same...

    Afaik, he's sampling the RGBI bits with PIO and pushing them to a frame buffer clocked out over HDMI with bare-metal assembly. If you want to avoid tearing, you'd need to at least double buffer...

    Unless you are slewing a VCXO, it's impossible to have true genlock. You can match timing.. but that's not genlock in a broadcast studio sense. Amiga users have so corrupted the meaning of that...

    Considered that. Amiga 'chip-memory' is poorly named. It's really graphics ram. If that is the only RAM in the system, it is also used for everything else. Agnus contains the blitter and copper...
  8. Amiga 2000, 2MB chip-ram upgrade, and Genlock timing

    I have a couple dead and one dying Amiga 2000s - the later with extensive battery leakage but still works. I was planning on replacing the MB in the dead ones with the rescan/remake by Floppy209. ...

    It's more than that. You NEED the '245. Even if you put a pull on the unbuffered ISA bus, there are strong PUs and sometimes totems on motherboards that will still cause indeterministic levels when...

    You would have to write twe different values - one to the main CGA window and a different one to the aliased window / back to back - then read from either. It's a very contrived use case. I doubt...

    I don't see how that's possible. The only electrical stress issue would be if a high side and low side driver are turned on at the same time causing a low impedance path between 5V and GND (aka a...

    Yes.. the only thing worse than micro USB is micro USB 3.0! I'm not sure I still have any products that came with one that isn't broken off.

    Bitching, ranting, yelling, or any such diatribe about mini-USB is never considered a 'rant'. I always consider it well thought-out rational sane exercise in perfectly normal critical thinking.

    It's literally what it says it is. It is a SDLC adapter (Synchronous Data Link Control). It's a synchronous serial (RS-232) card likely used for connecting to an IBM SNA network.

    That is a IBM 5250 TwinAx Terminal Emulation card. The DA-15M goes to a TwinAx dongle.

    I was about to bring up Diablo. Not sure if those qualify as 'Xerox' products or not but they did carry the name plate after the acquisition. I gave away two 3200s a few years back as I had no...

    I just wish you had put the connector and riser plate on the correct side. It is meant to go downward, not up. It would have just taken 1 more spin. So you are using up two plus slots with this...
