Good news: I found my old Hitachi mono video monitor.  It has a composite input and should be nicely representative of bog-standard TV resolving power.  It's so small that it consumes less power than my big LCD monitors.  And it still works, despite it's last electric safety certificate reading August 1984 - it can't have been anywhere near new even then!

Bad news: it has a very weird input connector.  I remember borrowing the adapter that fitted it during my amateur radio days.  I'm fairly sure that it's still attached to my good 2-metre antenna.  Just one small problem - I CAN'T FIND A FIVE FOOT LONG ANTENNA!

I seriously need to tidy up in here.

Does it have a DIN type socket. I had a Hitachi TV with RGB analogue input in teh back. I matched a DIN so I just made my own. Had the Archimedes running on it for awhile.

Nope, this is a professional-grade HF socket with a screw coupling - basically a couple of steps up from a BNC.  About an inch wide with wicked-looking serrated edges.  Can't remember the name of it offhand but it does have one.

Found the antenna eventually, where the removals men had conveniently taped it to the back of some shelf struts.  No cable, no adapter - I assume it still exists, but no idea where any more.  Tore apart a known-bad cable with an RCA at one end as a temporary solution.  Found that my test machine was going to require some serious coaxing (haha) to convince it to output anything on the analogue output.  Dug out BBC Micro - has BNC socket for composite video, not RCA - why?  Dug out Spectrum +3 - has no composite output, only UHF.

Now looking for correct adapter for more modern computer.  I'm not entirely sure that the 12-year-old Apple one I found is suitable for a PC video card, and it also looks suspiciously ratty for a cable that's never been used.

While tearing apart the spare room, found a lot of things that I'd previously been looking for (colorimeter, TrackIR, old Airport UFO, and my one good working 5.25" floppy drive) - directly underneath where the little old CRT had been.  No wonder I couldn't find them.

Eventually found original cable I was looking for, in a completely different box at the opposite end of the flat to the rest of my radio gear.  It changes BNC into the big socket, not RCA - time to dig out the Beeb again.

Sounds like a PL259. Easily available from any ham or CB supplier.

(The socket is an SO239. They have different numbers.)

I've a Sanyo VCT 5000 Betamax recorder, and that has a BCN connector on the back for composite input.  I know you said your Hitachi had the bigger version, but even BNC is more pro than RCA.... 

Anyhow, I used to connect my C64 to the Sanyo via that to record opening captions onto tapes before I used them.

(For some reason, I always manage to transpose BNC to BCN which is the acronym for Birmingham Canal Navigations)

10+3  Is this sum generator out to get me?

That certainly sounds familiar.

Anyway, the verdict is in:

- Using 256 lines per field thoroughly fills the visible area vertically.  So much so that any vertical misalignment will result in part or all of the first or last line or text disappearing behind the surround.  My Beeb and this monitor are about 20 scanlines misaligned, so no *TV command completely fixes it.  Using 240 lines per field would be more sensible.

- I can't test whether the interlaced doubling would be resolvable because the Beeb can't (easily) generate such a signal.  I could probably hack it using the VBI and a palette change in theory.

- 320 dots per row is completely resolvable.  640 dots per row isn't, but a bold 8-pixel wide font is still perfectly readable, and thin lines (in either normal or reverse video) every 4 or even 3 pixels still show clearly.

- I'm going to need to do some more shopping if I want to use this monitor with the R-Pi.

Oh THOSE....  I remember them, the aerial connection on my old CB unit (Hello late 70s!!!) had them.  Wasn't CB a dreadful fad?  *g*

I have just had email from a well-meaning reader telling me that if I propose going to China to bring the boards up, I should be aware that I will need a visa.

DO YOU BLOODY THINK? At least the guy telling me I should be sure to book freight space for the boards (he was sure we hadn't thought of it) was commenting rather than emailing me personally. What on earth do these people think I busy myself doing all day?

You may need to buy a plane ticket too. Several, if other people are travelling with you. Hope this helps.

Here is a question?  What country lets you in anymore without proper paperwork?

I can't even go to Canada without a passport anymore.

Its hard to beleave that people say such dumb things, some people just don't think before they talk, but I think some are just genuine idiots.  Since I have been moderating here whenever there is an anoying, stupid, or just something that has been asked to death I have been logging usernames and ip numbers that go with these posts.  I thought possibly someone was making a buch of accounts and asking redundant or inane questions over and over just to mess with us.  My conclusion so far is that there are in fact many unique inqisitive numbskulls out there.  Nothing has matched yet.

You might be amused/appalled (delete as applicable) to learn that one of the lab activities in third-year university was a Caesar cipher, a close cousin of ROT13.  At this point we were just switching from Java (as used earlier in the course) to C/C++ which would be used for more serious concepts.  Caesar was effectively just a shakedown cruise to make sure we could write, compile and run a simple program in the new environment.

I wrote the central code in about 5 minutes, then turned to my lab partner and asked him to describe how it worked.  Bear in mind that Java, which we had supposedly been using every week for the past two years, has many syntactic similarities to C.  Most of the code I had just written was probably legal Java.

He hadn't the foggiest.

It's also a great example of how a reasonable knowledge of Unix commands can help you avoid programming entirely:


tr a-mn-zA-MN-Z n-za-mN-ZA-M

It would make a good blog post - perhaps a sketch of a whole week. And include the rest of the team too.

I may have mentioned that some of the email I get makes me feel a bit like screaming. I thought you would enjoy an example that just arrived. (Not, by any means, the first of these that I've had today.) The pertinent thing is that in order to have found my address, this guy (name redacted) must have had to do at least a minimal amount of digging through the website, and will have read something on the contact page telling him to check the FAQ first.
