They never fixed the chip. Easy fix then! Better than the Pentium 'divide by zero' problem. A hardware fix was easier than recoding all software to trap for zero divisors (which arguably should be the case with good software design practice anyway). 8 2 2 Link to post Share on other sites More sharing options...
RMweb Gold Popular Post DaveF Posted May 2, 2023 RMweb Gold Popular Post Share Posted May 2, 2023 I've now got a few minutes to write something, I had several minor interruptions earlier. I had a walk along the Links and beach this morning and found that the temporary fence has been put back up on the beach with signs saying it is to protect breeding shore birds. This time there are more posts and they are in the sand more deeply. It might be for terns. There were a number of larks ascending and descending singing loudly so it was a lovely walk even though it was a grey sky. On the way back I remembered to post a card and gift token to my godson which I mentioned yesterday,I've worked out he is 28 now. I was home in time for coffee and then had a long chat on the phone with a friend, as usual we put the world to rights and commiserated with each other about our health issues - his are much worse than mine - I should consider myself perfectly OK and should not complain when I hear what he has to put up with at times. After a simple chicken salad I felt tired, probably because I woke early so had a nap before going in the greenhouse to check the plants. I put in the young plants which germiated a week or so ago on the kitchen window sill. I stll have a few more things to sow sometime this week. Then I had a delivery of a new footstool to replace one which is worn out, so far I am pleased with it. Evri delivered it on time and with no problems. I've just watched a programme on BBC 4 about travelling on canals, this time it was from Kaedby through West Stockwith on the tidal part of the River Trent and up the Chesterfield Canal. Very simple but enjoyable. Back in the1960s Dad kept his boat at West Stockwith for some years, there were moorings there along with a small yacht club, so the programme was particularly interesting. You could either travel upstream or down to the Humber and out to sea. In those days the Chesterfield Canal was closed, it has been reopened. About 60 years I rowed a dinghy along the first part of it and walked along other bits! Shortly it will be time to watch the French series of Maigret and then I think an earlyish night.

RMweb Gold Popular Post Hroth Posted May 2, 2023 RMweb Gold Popular Post Share Posted May 2, 2023 In 1986 my parents and I took our family narrowboat on a long circular trip from Chester that included the Leeds and Liverpool canal and the North East Commercial Waterways. One portion was the passage from Keadby to Torksey on the Trent, we followed a small coaster which moored at Gainsborough. We locked up onto the Fossdyke to moor overnight before proceeding to Newark the next day. 20 Link to post Share on other sites More sharing options...

Sixty quid, to you sir..... Bear here..... A rather productive day today; this afternoon's fun started with phoning the MG Dealer that supplied Mickey - this time I spoke to one of the Bosses who sounded much more positive about being able to offer a repair; photos have been emailed and I await a response. Then I totally lost all common sense (or what little I had left) and decided that The Bearmobile was in dire, dire need of a bluddy good wash - Mickey now gleams once more and there's no sign of the Birdsh1t that once adorned the paintwork; one of the downsides of having a bluddy great tree overhanging the front garden - complete with Pigeons that seem to return year after year and cr@p everywhere. B'sterds. In other news.... Whilst I was washing Mickey an Amazon delivery guy arrived at Bear Towers clutching a parcel .....for the same Guy that (a) doesn't live here, and (b) this isn't his address either - the house number is the same but it's the wrong street name and post code. Yet the (obviously foreign) delivery driver showed me the map on his phone and the little map piccy shows the "dot" on Bear Towers..... I guess a lot of Amazon Drivers can do their numbers and little pictures but haven't progressed to reading yet.... I've a feeling this won't be the last parcel for him that I see - hope he buys something really, really good n' expensive next time - a nice small milling machine, for example. If he buys an American Fridge- Freezer I'll be totally b*ggered, however..... Bear saw a bit of "Love your Garden" earlier....they had SEVEN decently sized sheds in their garden. Just sayin'.....

Around that time DEC had a PDP-16 card with 16 ferrite cores and you could create ROM words by threading wires through the cores where you wanted a '1'. Probably only allowed for 16 words. It was quite cool but it was not small. I did work on an even earlier machine where the "initial orders" were created by threading plastic or ferrite cores in the first plane of a core-store. 8 2 4 Link to post Share on other sites More sharing options...

Some years ago he did an interview for a living history project connected to an exhibition about the people of Birmingham. We knew he had been in Normandy and through Belgium including Caen and the Falaise Gap, but he just dropped out the name 'Operation Market Garden' in the conversation. He never said more about it but it turned out that his Redcap Provost were attached to ground troops trying to link up with the airborne attack. They did manage to capture Eindhoven while they were there but were then stranded for the winter due to ground conditions. He was sent home on leave where he met my mother before being transferred to the Indian Army. I had a colleague who was also with the ground troops trying to link up with the airborne troops. He was a sergeant in the REME and he received the MM for erecting a Bailey Bridge while under fire. 11 2 Link to post Share on other sites More sharing options...

We used to have a couple of non-interpreting single card manual punches in the office to avoid the need to walk across to another building to get the “punch girls” to correct a single card. That’s not to say we could all use them - you had to know the punch combination for each character. One of our system programmers could use one and carry on a conversation at the same time. 8 6 Link to post Share on other sites More sharing options...

Roasting a cluckbird on average every other Sunday we are left with at least half the meat for Later Ron. Dr. SWMBO, not one for re-heated meats, came up with the idea of "Coronating" it. Mix Keen's curry powder (other brands are available but she insists ..... ), mayonnaise, mango chutney, raisins and flaked almonds in a bowl; a little salt and pepper if you wish. Roughly chop cold chicken meat and add to the bowl. Mix the goo and the meat together well and serve. So easy. And if you still don't use it all the remains will still keep for a few more days. As a student I learned how to get six decent meals from a chicken; we still do. Two breasts, two legs, trimmings and soup back in the day. Nowadays it's usually two roasts, two Coronation Chicken salads and two Coronation lunches. Plus stock or soup now and again in season. 15 3 Link to post Share on other sites More sharing options...

Yes, but IIRC we had that chip in '73 (it might even have been late '72 but maybe not.) The planning went back a bit before that too. I also have a lot of experience with the earliest ePROMs and they were a complete load of crepe 😁 To avoid the manual bootstrap a small fusible-link PROM would have been ideal but I don't think they were around or easily obtainable quite then. You have to remember that at that time there was no such thing as a micro-computer. There were plenty of competing minis but the whole idea of a programmable micro-computer made little sense (or so it seemed). 8 3 1 1 Link to post Share on other sites More sharing options...

Then your text books clearly missed the point. DEC's PDP-16 (a product of the early 70's) was not intended to be any sort of general purpose computer. It was for process control applications, a predecessor if you like for the way microprocessors are embedded in everything from pencil sharpeners to nuclear power stations. DEC sort of missed the boat but they had the right idea and they understood that a small cheap-and-cheerful control system needed an easy way to boot-up. 7 4 Link to post Share on other sites More sharing options...
RMweb Premium polybear Posted May 2, 2023 RMweb Premium Share Posted May 2, 2023 Oh yes.... And a Rant to end the day on...... Bear has one of those clever hose pipes that magically "grows" in length when you put water thru' it.....or did..... I was fighting to get it to connect onto the quick-release pipe coupling on the outside tap this afternoon (it was a bit of a p1g the last time I used it too); when I eventually managed it and turned the water on it was fine....for a few seconds, after which it started leaking big-time thru' the wall of the pipe itself. Turdycurses - another one bites the dust 🤬 They seem to last for 3 years or so, after which they give up and die. Fortunately I have a decent old-school style of hosepipe in the shed so that's now the go-to jobbie; I'll not bother buying another clever one for the foreseeable whilst this one does the same job.

My degree specialized in electrical power generation/distribution and linear control theory. By the mid-80s there were a number of microprocessor-based microcontrollers in the control lab. That had become the main focus for the control theory teaching staff projects. A third-year project involved a 6502-based system running (of all things) FORTH, rather than "bare metal" assembler. (It turned out to be slightly too slow for my project.) My undergrad thesis was a process control lab setup using a PLC for later student experiments. 9 4 Link to post Share on other sites More sharing options...
