Some issues you may encounter are: Motherboard size. An AT motherboard is 13 inches from front to back, while the ATX standard mandates 9.6 inches. If a case takes an Extended ATX motherboard it should take an AT one. Mounting pillars / holes. On an AT motherboard the position of the holes is not precisely defined by the standard, whereas ATX is more ...

Some of the most available adapters which allow to connect a "modern" mouse to an Amiga are: Real USB mouse and joystick: The Ryś MK II. This is a very flexible device which supports not only USB mice (including but not limited to PS/2 ones) but also digital and analog USB joysticks. It is even capable of outputting joystick signals compatible with the ...

The short version of this answer boils down to something pretty simple and easy: Cheap, easy: try more different keyboards with your passive PS/2↔USB pin adapter OR Not cheap, still easy: buy a really expensive, nice keyboard that also works over PS/2 and take it as an excuse to get yourself a nice keyboard for day-to-day computing! The passive PS/2↔USB ...

Not at all. Well, at least not with any simple plug / converter. USB works completely differently from PS/2; any converter will need an active component. And no, those pesky PS/2-USB plugs that were given away with many keyboards during the 2000s are not active, but just rearrange wires - the keyboard controllers themselves were able to handle either ...

Maybe the most difficult task is to find a plug for the Apple AudioVision connector. Here is its pinout, taken from http://pinouts.ru/Video/audiovision_pinout.shtml , in case you find a suitable connector and want to do the wiring by yourself. 1 Analog audio ground 2 Audio input shield 3 Left channel audio input 4 Right channel audio input 5 Left ...

Bus: yes should negotiate. Device size: possibly okay. If your OS can issue (and your scsi controller supports) a read(16), then you'll get the full capacity. If it only supports read(10), then it'll look like a 2TB volume (assuming the drive is bigger!). I've heard of some random old controllers that didn't support read(16) and caused problems for big ...

I want to find a way, using software, to interface my laptop and the PS/2 keyboard/mouse using the adapters I bought. Assuming you want to use the passive PS2-to-USB adapter you just bought to plug it into a USB port on your Windows 10 PC, then this will not work. The passive PS2-to-USB adapters require the keyboard or mouse to be multi-protocol: The ...

The Ryś MKII adapter by Retro 7-bit allows connecting USB mice and joysticks/gamepads to the 9-pin Amiga port. It's a true USB device so it's not restricted to PS/2-compatible USB mice like other devices mentioned here. It's available from a number of Amiga specialist shops (there's a listing of resellers on the page linked above).

Almost all SCSI devices are either 8-bit wide and have a 50-pin connector with single-ended (open collector, no differential drive) electrical signals, or are 16-bit wide, using LVD differential signalling AND having a fallback capability to work with single-ended drives if the wiring harness connects the right sense pins. There are 68-pin data connectors (...

ADB keyboards and mice are readily available on eBay for as little as $10. Apple used ADB from 1987-1999 for Macs and the Apple IIgs so there are a lot of devices around. The monitor adapter from Apple AudioVision to VGA is harder to get and I defer to @mcleod_ideafix.

For a while, many PC cases were made to be both AT and ATX compatible. This would have been in the mid-1990s, during the changeover from Socket 7 to Slot 1 (Pentium II) and Super Socket 7 (AMD K6 series) when motherboards were made in both shapes. You could try looking for cases from that period, or from the early 2000s. AT motherboards (in practice, ...

You are asking how to convert the analog video output from a console for using it on a modern HDTV system. The usual answer is to use some kind of converter from the best video output option available in the console, to the best video input available in the TV. Chances are that your TV already has the right kind of input. In this case, you won't gain ...

It depends on whether you also want to modify the N64 to support RGB output. Without modification, the best output to use from the N64 is S-video. Cables are commonly available on eBay for the N64 that support S-video, and there are upscalers that will convert S-video to HDMI 1080p. This unit from Amazon looks like it would do the job. You can also get far ...

Here is a guide on how to convert an old Microsoft serial mouse to work in the Amiga's mouse/joystick ports. Maybe the guide can be adapted for modern optical mice. (In fact, here is a thread about someone who seems to be claiming to do just that.) And here is a serial mouse driver for Workbench, all it needs is a serial mouse and an ordinary 9-pin to 25-...

No, for many reasons. The yellow connector that you are talking about is called composite video. It's called "composite" because it combines several signals: vertical synchronization, horizontal synchronization, blanking, luminance (the black-white part), and chrominance (the color part). No model of Macintosh bothered to combine these signals, ...

No. The Mac SE vertical and horizontal scan frequencies (designed into both the CRT yoke and the analog sweep generator circuits) are different from NTSC (and PAL) composite timing. And the Mac SE analog board requires separate vertical and horizontal sync inputs, not just a video signal. The analog board sync inputs need to be at TTL voltage levels, ...

Check out this source file for the technical details of the keyboard: https://github.com/mamedev/mame/blob/master/src/devices/machine/myb3k_kbd.cpp The source file contains all information you need to build your own keyboard. The serial protocol that the keyboard speaks to the host computer is unfortunately not even remotely similar to standard PC ...

The cartridge port first appeared on the Electron's Plus One expansion; those on the Master vary the meaning of a few pins but are mostly compatible — ROMs should work without modification (subject to the software, of course), but hardware is likely to be machine specific. The full pinout, including documentation of the machine differences, is contained in ...

While you can still get 1980s-vintage joysticks, some of the PVC cable sheathing is beginning to de-plasticize with age, so the cable can effectively fall off. Before I realized they were basically unreplaceable, I threw out three Konix sticks that had that problem … Building your own isn't hard, though. I made a ridiculously over-engineered box out of 6 mm ...

This is not the elegant solution you are requesting, but it will solve the problem: Buy a Tripp-Lite B042 series KVM switch. Specifications: https://assets.tripplite.com/product-pdfs/en/b042008.pdf This has two USB inputs for a keyboard and mouse, and outputs to USB or PS/2. There is an adapter that connects to the USB output connector to make it work as ...

Most (though not quite all) Android devices support operating the USB port as a USB host, either triggered by the usual OTG role pin on an adapter cable or by vendor-unique software setting. There can be various complex interactions with charging and ability to supply power to a peripheral, but for a low consumption device like a USB serial converter it ...

Any power supply within about 5% of the rated voltage should work, so a 16V supply (or a 17V one) should work. If you're getting a modern switch-mode supply, you want the amperage rating to be at least as large as the one you're replacing, if not larger: I'd go for 2.5A or higher. If you're getting an older transformer+rectifier supply, on the other hand, ...

The first thing to do is check the label on the computer to find out what its power input requirements are (it might be different from what the label on the power supply itself says). Many devices will operate on a range of voltages and currents, and any power supply that falls in that range will work. For example, a Soekris net6501 can be purchased from ...

I would say there are 3 main difficulties: AT power connector, versus ATX power supplies. As you've noted, adapters are available to convert from ATX to AT, you will just need to figure out what to use as a power switch. The AT used the main power supply disconnect as the system power switch, while ATX moved to 'soft power' via a motherboard connector. AT ...

Given this is a PC/XT clone, there are two difficulties: adapting the unusual plug - it's unlikely you find a ready-made adapter, you probably have to make it yourself, have one made, or fit the original cable to another keyboard protocol - the PC/XTs used a different protocol - keyboards in the late 80s, early 90s were often switchable; modern AT-style ...

Another option is to replace the innards of the original Amiga mouse with a new laser PCB. There is this one sold by AMIGAstore.eu that supports most of the popular Amiga mice models. Doesn't solve the ergonomics, if that's really a problem, but makes the original-looking mouse just a little bit less infuriating to use.

I used to keep my own cartridge to use on the 10-or-so BBC Masters we had at work. I'd plug it in when I started work on one. It was just my favourites...Wordwise (WP) and Exmon (debugger/disassembler), I seem to remember.

If you want some DIY, you can try my opensource project, usb2ps2conv. It lets you make a USB-keyboard to PS/2-computer converter out of an STM32F401C-DISCO board and a couple of resistors. This project is currently in development, but it's already functional enough to control a Linux PC via a USB keyboard plugged into a PS/2 port through this converter. The ...
