My modified calculator cable is probably the Japanese calculator type, although it seems to work OK with 163-type sockets despite the mention of the pin diameter of the 163 being a little larger (presumably the receptacles within the plug are pressing up against the pins of the 163 type socket, but not actually fitting over them). I would much rather have the right type, obviously! Big thanks to our own Brent Hilpert for the great reference! Indeed :-) Jules
RE: Old HP test equipment power connectors...
Right now, I'm cursing the guy who thought that the cloverleaf or mouseketeer power receptacle was a good idea. I'm sitting here looking at an HP ScanJet wondering if it would be worth the effort to replace it. Fer heaven's sake, what was wrong with the IEC connector? If you mean the one that a mad friend of mine calls the 'figure of 12' (on the grounds that the 2 pin one used on radios, etc, is often called a 'figure of 8') then I believe it _is_ an IEC connector, in the same standard as the more familiar 'kettle plug'. The thing that annoys me about this connector is that a rewireable cable socket does not seem to exist. Just moulded cables, which I dislike on the grounds I can't check that the wires are properly connected (and not just held on one strand). A rewireable 'figure of 8' does exist, but the version I have seen doesn't have a proper cable clamp. -tony

Thanks for the mention. Note the 163 name is my 'best estimate' for the type name.

Re: 8-bit Computer TV Channel Use
If you do end up building a custom solution, I have a feature request :-) It would nice if the device was also a frame grabber that could, under command, snap one or more frames of the legacy video and export it over USB perhaps. This would allow us to document operation of legacy software with high quality frame grabs since persumably you'd have access to the image in a relatively good quality domain before you turned it into DVI/HDMI or whatever.

That was already on my possible-feature list! ;) If I do end up using a Zynq FPGA, then hanging things like Ethernet and/or USB OTG would be cheap to add. Those wouldn't be my first priorities to implement in firmware, but I should at least include stuff options for the connectors and PHYs on the PCB. I'm not sure yet whether I'd start with a dev board or go straight to a custom board. The Zybo board is cheap and has the cheaper Zynq chip that I'd like to target, but it lacks good physical connections for a couple of relatively high-speed DACs, and it only supports 720p HDMI output because it lacks a dedicated HDMI PHY. I could get 1080p and an FMC connector out of the much more expensive Zed Board, but it uses a larger Zynq chip that would be prohibitively expensive for this project, and if I had to build a board with an FMC connector for my analog front end then I'd already be making a board that's too advanced for me to solder up at home, so I might as well thrown down the FPGA, too, rather than spending $500 on a not-quite-right dev board. Sigh... This would allow us to document operation of legacy software with high quality frame grabs since persumably you'd have access to the image in a relatively good quality domain before you turned it into DVI/HDMI or whatever. Agreed! Grabbing some live video might also be an option, but I think that would be a smaller incremental value add than getting high quality single frame grabs. BTW, every good project deserves a good project name. I'm tentatively calling this one Crazy Cat Lady. It has a nice ring to it. -- Mark J. Blair, NF6X n...@nf6x.net http://www.nf6x.net/
