You said 74S267 but is that the correct part? I know 74S287 to be a PROM with 256x4.

Well spotted. I was clearly asleep when I wrote that. It’s a 74S287.

Trying to locate something which is both available and has programming data sheets and isn’t extortionately priced. The Tesla MH74S287 actually looks the best bet at the moment.

Have opened a case with the seller of the original part now. Their service and communications are terrible so I’m just claiming it back via eBay now. They’re disinterested in dealing with it or sending another part out and are pushing back asking to give it another couple of days after it has been missing for two weeks now on a RM 24h delivery I paid for. So screw them. User test-equip forget it. Shame because they have a lot of tek and HP parts.

Edit: if anyone has that ROM (U1605 on vertical amp board) on a scrap 465B and are willing to part with it I am interested so I don’t have to futz programming a ROM for it :)

To escape the the heat, visit fortifications.

To manage wine buying habits, install reinforced springs on your car.

From Fort d'Uxegney just west of Epinal. Meter is from the original 1914 installation of "Groupes Electrogènes" in the fort.

Today, having visited the immaculate condition fort above, we're going to teach the realities of war, with a visit to forts Douaumont and Vaux, along with the actual boneyard,  outside Verdun.

Replying to self - eBay decided in favour of me almost instantly. Refund on the way. Good job as always  :-+

Discovered recently that due to the chip shortage, the availability of shit Arduino clones is pretty bad and the prices have gone through the roof. Considering buying the last decent "on device programmable microcontroller and electric swiss army knife" at the moment, the BBC Micro  :-DD. That and the user and printer ports give you a 6522 VIA worth of IO to play with, BASIC, assembly support and decent documentation...

EV's and non-gas heating is driving  three phase supplies for some new build housing though.

You might need quite long extensions, from what I can make out (from observing single phase power failures) the phases down my street change about every six houses.

From observing the telephone poles, in my road they change every house, and every house could easily tap all three phases.

Since I've mentioned before my struggle with the diabetes and getting my blood sugar under control I'll give an update which is good news. Checkup with the doc on Wednesday and had blood work done. The purpose was to check my A1C which represents an average of your blood sugar content over an approx (I think) 3 month period. For reference if your A1C is approx 5.5 or below you are normal (non-diabetic). If it's approx 5.5 to 6.0 you are considered "pre-diabetic". Anything above 6.0 and welcome to the low carb club. Back in April my A1C was a dangerously high 8.9. Which is why I went on insulin. Wednesday's blood work shows an A1C of 7.2. So I'm making excellent progress. And the daily insulin dose has been upped from 15 units to 17 units. If a diabetic can get their A1C consistently between approx 6.5 to 7.0 they are considered "controlled". So I'm not far from that objective. I go back to the doc in September and I hope by then to be within that range.
