Анализ медицинского анализатора: Bayer Clinitek Status+
Приветствую всех! Думаю, многим из вас доводилось в рамках диспансеризации или по предписанию врача идти в лабораторию и сдавать что-то на анализ чего-то. А ещё, уверен, многие хоть раз задумывались: а как вообще работают приборы, которые там стоят, и как они вообще определяют наличие тех или иных гадостей в вашем организме? Самое время узнать это. Однажды ко мне в руки попал один из таких приборов. В сегодняшней статье попробуем его запустить, посмотрим, что у него внутри, и, конечно, разберёмся, как он работает. Как водится, будет много интересного. Press F1 to continue

@wyatt As I understand it, there isn't enough data on the 68000's stack frame to properly recover from an aborted instruction (bus error or address error), but there is enough to recover from an illegal instruction and emulate it. That's what the line A and line F exceptions were originally meant for: emulating things that Moto was going to put in later processors.

Having an awesome time putting my new Parceiro II+ that just arrived in the mail through its paces on my Amiga 1000. I had the original Parceiro and it was a game changer, but the Parceiro II+ is just a polished vehicle for perfectly experiencing the Amiga as it was in its heyday.
Kickstart in ROM (no floppy needed!), HD / volumes on removable SD card, 8MB FAST RAM expansion, real-time battery-backed clock.
And I've been focused on the Kickstart 1.3 partition so far; I've hardly had a chance to play with the KS 2.04/WB 2.1 and AmigaOS 3.1 modes / partitions.
Such amazing work, David Dunklee! What a way to make the Amiga shine.

There are quite a few oldschool Amiga OCS/ECS demos that will run as intended, perfectly, smoothly only on base Amiga 1000, 500, 2000 systems with 68000 CPU -- unaccelerated. One example is TBL's Eon (2019) -- an incredible demo.
I've encountered a few games that fall into this category also.
Will these run properly with 68000-emulator accelerators such as the PiStorm? It emulates the 68000, but can it do so with 100% never-failing, cycle-exact precision when operating as a base, unaccelerated 68000 at 7.16/7.09 MHz?
The demos I speak of fail to run or run visibly broken with most accelerators, including my A2620 (14.32MHz 68020).

If you love Assembly, I am sure you'll love my #UltimASM #DSL it allows you to design the Assembly of your dreams or to code in #6502asm , #MC6809 , #mc68000 and even #VAX #ASM on #RISC_OS (and all other supported platform by my #UltimaVM).
Want to know more? Come at the RISC OS London Show Saturday 25th October!

Novomatic Coolfire. Самый навороченный игровой автомат двухтысячных
Приветствую всех! Пару лет назад я уже рассказывал про игровые автоматы. И вот сейчас ко мне в руки попало довольно интересное железо — Novomatic Coolair, игровая платформа от одного из самых продвинутых производителей такого оборудования. Сегодня мы узнаем, как были устроены «топовые» игровые автоматы и как заставить работать начинку от них. Заодно соберём своего «механического гангстера», выиграем первый миллион и тут же его проиграем. Как водится, будет много интересного. Congratulations! Jackpot won!

I just found my Sinclair QL lurking at the back of the garage. It's going to take a bit of work to get it going again.
I built it into a metal toolbox to sit beside my desk and used a separate keyboard, which was borrowed from a VT100 and rewired to work with the QL.
My QL had not the usual 128 K of RAM, nor was it expanded to only 640 K, but I had 656 K, with an extra 16 K battery backed on a board which I could also use as an EPROM emulator when doing things with other micros. That board also contains a Dallas clock chip, so I didn't have to set the time everytime that I booted the machine up.
The extra 16 K of RAM was actually in the slot usually reserved for a ROM cartridge so it usually contained the dongle from Metacomco's port of the Lattice C compiler alongside a bit of extra code of my own.

I am considering the configuration of my Amiga 2000 w/ 68020 accelerator... I would appreciate opinions from drivers of slotted Amigas, here.
I have an Amiga 2000 with SCSI + SCSI2SD, 4MB 16-bit FAST RAM, 1MB CHIP RAM, etc. It also has an A2620 68020 accelerator (14MHz) with 2MB 32-bit FAST RAM which is meager, but makes things noticeably faster on the Workbench. Most of what I do on this is watch demos and play games, though. All I do on desktop, really, is use AmiTCP and ncftp to bring files over and run IMP sometimes.
I recently downloaded the Amiga demo 'Downslope' and noticed it's less fluid / smooth with the accelerator enabled. I've seen this before here and there, but assumed that the accelerator was doing my a solid in demos - giving a bit of a boost.
I commented about this in the Pouet 'Downslope' thread and the developer came in and commented,
---
"Accelerators often introduce an asynchronicity between CPU and chip memory, which adds to chip access latency.
This can be worsened by the occurrance of many interrupts, which can cause additional strain on memory on a higher CPU.
If we are unlucky, not even the much faster execution time of the higher CPU can make up for the additional latencies and strain on chip memory.
It's a matter of focus on the target. There are side effects on higher CPUs which are difficult to anticipate, and usually you have only a limited number of machines for testing."
---This makes sense, I suppose. Is this common? Are people with '030, '040, '060 accelerators having a lesser experience with demos due to CHIP RAM latency than with base '000? Certainly in some scenarios the more powerful CPU helps hugely for demos and games alike - I've seen this on my '020. But, yes -- demos are the most tightly coded of all Amiga apps, certainly. To the metal, etc.
So I am wondering now, should I remove the accelerator to get the most out of OCS/ECS demos on the system? Yes, I can disable the accelerator with a right mouse click at reboot, but that gets in the way of keeping Degrader's PAL state in effect, causing a hassle. (it's an NTSC A2000, unfortunately).
Anyone been down this road? Thoughts?

It's easy to forget just how huge 68000s in DIP format are. There are a couple of tubes of these 8 MHz parts at A1 in Etobicoke. As ever, the price will be highly dependent on how amusing your haggling skills are.

Got a real 68000 computer to hand? Can you run a bit of test code? There's a bit of doubt about a test suite:
> One of the tests in the repo is for ABCD D7, D7, where D7 = 0x397C714F and the X bit is clear. The test specifies the answer should be 0x397C7104
question is from

Boosts welcome of course

I was in need for a vector graphic of a #MC68000 for my "framing" project but i didn't find one. So i made it by myself. It's the most komplex SVG i've ever made #Atari #Amiga #m68k #retrocomputing
