Welcome to #MOVember, one asm MOV instruction each day.

The Motorola MC68000 has a BEAST of a MOV instruction.
Official assembler mnemonic: MOVE. Refreshingly clear!

You could move to and from registers and/or memory. 8-, 16-, 32- data sizes. Post increment, predecrement. Including memory-to-memory moves (*Ferris Bueller soundtrack voice*: Oh Yeah).

`*d++ = *s++` is a single instruction in 68000.

Officially destination on the right: MOVE A7,D0 copies the A7 register to D0

Please 🔁

#68k

Screenshot from the M68000 Programmer's Reference Manual showing the bit-encoded layout for the MOVE instruction. bits 15:14 are 00, selecting the MOVE instruction; bits 13:12 select size; bits 11:6 select the destination register and mode; and finally bits 5:0 select the source mode and destination.

Day 5 of #MOVember

The Z80 powered my first computer (ZX81), and was the first machine code that i learnt.

When is a MOV not a MOV? When it's a LD! The Z80 is a compatible extension of 8080 that, for copyright, has a different assembler syntax.

MOV, STAX, LDAX, MVI, and others have all been unified as LD (load).

A is the best register, and supports the most addressing modes:

LD A, reg ; from register
LD A, (HL|BC|DE|IX+dd|IY+dd) ; indirect
LA A, (nn) ; external addr

and the reverse.

#Z80

Extract from Z80-CPU Z80A-CPU Technical Manual, showing a table that shows the possible addressing modes for source and destination for the 8 bit load group, and their encodings. It's quite bewildering, but a core block of moves from one register to another dominates, with vertical streaks and horizontal streaks that represent LD to A (accumulator) with more possible modes, and LD from A with similarly more modes.

of all the different processor instruction sets I’ve forgotten, the Z80 was the easiest to pick up and then forget. And the 68000 was the one I wished I’d spent more time using.

The 8051 is probably the one most seared in my memory as I had to write code for it before the assembler arrived (i
n the post fro the US I think).

While I was out for a walk earlier my brain titled the TV hit series “Donaldson and Creece, Lesbians at Law”. Sadly it did not give me any further details.

what is fun is that I am surpisingly ignorant about [uncleftish beholding] and so when reading about it in any form it's always like learning not just reading, so despite being tired rn and unable to remember many of the words in English, I do feel like I learned something of the subject - familiar words are not necessary to advance the concept for me. The concepts, of course, exist regardless of our names for them and being able to learn from this demonstrates that beautifully.

UK state overreach, misuse of abortion laws against patients

Reminder that abortion in the UK is actually illegal – we just disapply the legislation in most cases.

So, when The State can use this legislation against citizens, it can most certainly do so.

@lewdum Yes! It’s all a song and dance. You have to say the right words, have the right doctors, and fill the right forms in, and the law is dis-applied. There is no “right to abortion”, it’s just behind a legalistic process instead of a medical one.

hey so if you can swing it, now's a great time to look into picking up a few radios for you and your friends and your partners.

not walkie talkies, though. regular amateur ‘ham’ radios. they don’t even have to be expensive ones and you don’t even need to know how to use them.

just make sure they’re dual-band, which means they transmit and receive on both major frequency ranges (UHF and VHF—think AM and FM, but different) and high-power (at least 4 Watts but shoot for 8 Watts or more).

if you happen to be using money to acquire them (i feel for you and i get it lol) we’re talking roughly $15-40 each depending on stock / demand / greed. start with one and do some price-watching… they always go back down.

🤔 The US government is the most well funded in the world. We have Federal agencies dedicated to emergency management (FEMA). We have a robust network of highways. We have the best access to electricity and fossil fuels. Most US citizens are adults. Despite all this, when there is a hurricane, we struggle to evacuate a few million people from the path of a slow moving weather event.

If most Gazans are children, who have no fuel or electricity, how do they evacuate a million people?
