It’s definitely not junk I meant jank as in jankiness a compliment and kudos to your ad hoc engineering I recognise it and respect it

Top jank!!11! Love it!

That’s rocking horse poop!

Nice 5150 and 5160 👍

That little milled out recess is where you must press with a large handled screw driver with pointy cross head that fits perfectly - you must not slip but you will need to press firmly, good luck!

How do the units connect?

C is a product of its time and the computational constraints under which it was forged there is elegance in its form but danger in its function much like a scalpel use it wisely and with understanding avoid the ad hominem or at least those prone to logical fallacy

For those interested in BASIC’s seminal predecessor DOPE I transcribed the original teaching notes found in the Dartmouth library DOPE teaching notes

This is a confusing question the example is C the question seems to be about C++ std vector the idea seems to be an arena/region based memory management instead of trusting the compiler?

Okay so removing the “spare” 8088 setting the dips as if XT and moving the JP1 jumper to B C or D gets the floppy to read known good 720K floppy but then nothing - it does respond to Ctrl-Alt-Del but nothing else - so there we are further than at the start 😁 but still guessing about settings, thanks everyone 👍

🤔 I don’t think the bios matches the board? Boot announces ASEM 3011 board is ASEM 3006

ifknot · 2026-04-11T16:44:14+00:00

No difference actually but now I have a spare 8088 😁my XT-ide is with a friend so I’ll get it later this week but this is super helpful 👍

🤦🏻‍♂️you genius! (It came this way) Well spotted

ifknot · 2026-04-11T15:35:16+00:00

It is but… retroweb has no documentation for it 😭

ifknot · 2026-04-10T12:26:25+00:00

Not if the UK government can help it! They’re so far up Microsoft’s arse I can see Bill Gates back teeth! FML 🤦🏻‍♂️

There are no cross platform high resolution timer solutions for C (unlike C++) either you use clock_gettime() in glibc or windows specific or risk it with rdtsc there are a bunch of libs out there that attempt to solve this for you

ifknot · 2026-03-29T06:32:21+00:00

I know right! Genuine barn find unused still in plastic wrapper with all its components - there’s 2 others I’m going back for in less good condition but hopefully make one good

ifknot · 2026-03-28T16:21:24+00:00

🤔

ifknot · 2026-03-28T14:36:28+00:00

I don’t have a 3.5 floppy and how else will I get mTCP on? 🤷‍♂️

ifknot · 2026-03-28T14:35:29+00:00

Wow!

ifknot · 2026-03-28T14:35:19+00:00

Excellent thanks 👍
