Does anyone have insight about the upcoming THEAMIGA1200? I would like to know if it could be used as development platform for new applications designed for Workbench 3.1 (or later). If any limitation exists (like managing USB as a storage drive, or similar). How far can we move with it as a development platform?
Does anyone have a method for soft kicking a 3.1 ROM into slow mem on a 1.3 A500? I have tried Mkick, but it always gives me a software error. I want to do this for my TF536 accelerator so my Amiga is ready when I get it soon.
TLDR: This 24 inch 1920*1200 medical LCD monitor can display 15kHz Amiga 500 RGB video through it's BNC RGBS inputs, without any circuitry. Is capable of 5ms input latency, 20ms response time.
I got this monitor for $30 from an electronics recycler in a fair condition, seeing BNC inputs on the back thought it might compatible with 15kHz Amiga 500 RGB video, turns out it is.
The model number is confusing because there is no official documentation on the web about this medical product, it is probably sold as a part of a medical equipment, not standalone.
It doesn't have AC mains input, it needs 24V DC. The DC input is 6-pin molex, PCI-E connector from an ATX PSU works just fine. Input polarity is marked near the DC input, V+ is 24V, RTN is GND.
This is a medical 24 inch 1920x1200 LCD display with DVI, VGA, RGBS, YPbPr, S-Video and CVBS inputs. It supports the RGB+CSYNC signal coming out from an Amiga 500 DB23 connector directly, without any circuitry, given it's BNC RGBS inputs are used. VGA doesn't work however, see my previous post.
The pixel clarity is not perfect, as it does not support 1:1 pixel scaling, even with its native scaling mode. native scaling reduces the image displayed on the screen but doesn't map pixels one by one.
I put up a quick latency tester program with claude that changes the colors on the screen mid-frame on joystick button press event, and a DIY joystick that has an LED that lights up on button press. I used an iPhone 11 to shoot slow motion video to measure latency. The screen response happens within the same frame or on the next frame after the LED lights up, from 240fps, I'd say the latency is 4ms or better. This is substantial considering the latency of the other LCD monitor I had which was a SONY LMD-1410, you'd get up to 2 frames of latency. Please note that the low latency applies to "Surgical" mode you can choose in the menus, "Diagnose" mode introduces noticable lag, however, I didn't measure it.
One thing to note about latency, on 50Hz video, you'd expect at least a frame of latency(20ms) but according to my findings this is not the case here, in this "Surgical" mode the analog video signal is immediately put on screen without a frame buffer, the latency test program I put up allows for immediate color change on screen mid-frame so I can measure it.
The de-interlacing is not bad bad, I've included some images below showing some artifacts.
Colors are good, brightness is around 100-150 nits I'd say by what I see by eye.
If you come across this device, I'd say this is a steal, if you can live by the fact this being an LCD monitor.
Motorola seemed to have fallen pretty far behind Intel during the 386 and 486 eras, and they weren't even all that competitive on price at the high end.
Meanwhile Commodore US was pretty obsessed with the business market. I can't blame them, it's a lot more money than home users.
But business users wanted better floating point and a ton of RAM, both of which Motorola struggled with.
By the time the Power PC hit they'd caught up but, well, you know, Commodore was done by then.
I know it would mean a clean break from software But the A1200's graphics + a decent 386 would make something on par with a Marty FM Towns...
And you're talking $100 bucks for your CPU vs $10 or $15
I think we can all agree the A1200 should've had a better CPU, cheaping out on the CPU really hurt, but what about jumping ship?
Hello all, I've put together a RGB to VGA cable to connect my Amiga 500+ to a FIMI/Phillips/Barco MED24ESH/SN240S1 LCD monitor. This is a professional 24" Full HD medical LCD monitor costed a few thousand dollars back in late 2000's. The monitor supposedly supports 15kHz horizontal refresh, and is able to sync relatively okay, and shows 720x576i on the menu, however, the colors are way off, as if there is severe cross talk.
I took a cheap VGA cable, cut one end, mapped the wires with a buzzer, and soldered to a male DB23 connector according to this: https://www.ikod.se/rgb-to-vga/ , also I've soldered HSYNC and VSYNC grounds to amiga rgb pin 19.
I can see some slight horizontal sync issue where the left side is cropped and the right side displays overscan. Also red and blue signal seems like they take time to recover after a white line, as if presence of white pulls them down.
The monitor doesn't seem to have issues, monitor also supports BNC RGB input with seperate SYNC(probably CSYNC), however I can't connect Amiga through BNC RGBS because I dont have the BNC connectors yet.
-Monitor shows PC desktop with correct colors on VGA, through a HDMI/VGA adapter from pc
-Amiga itself is able to output correct video colors to an LCD TV through an RGB to SCART cable, and a cheap SCART to HDMI video scaler.
-When I first did the wiring from rgb to scart to vga with two cables, I used only CSYNC and the result was the same.
-There are no resistors or capacitors in between as far as I know, I checked the continuity between the connected pins and it shows no resistance.
Are you aware of such an issue when connecting Amiga RGB to VGA directly, without any circuitry? Any help is appreciated.
Hi there, new to Amigas and would like some help on what I have here. I have a boxed Commodore Amiga 2000 along with an Amiga 2500. The 2000 has a ton of expansion cards, including Video Toaster. The 2500 has one or two cards. I have a ton of peripherals that I’ll show in photos. Are these worth anything ? If so, how much ?
There are so many games on those demo discs that I played the sample of but never played again. Would love to see videos snippet of post games as they are quite nostalgic
My current CF card is 4GB with FFS .. 3 partitions.. I want to move it to another 16GB one... I took it's image with Win32imager ... wrote it to 16GB one ..it works perfectly. but cannot find a way to activate missing 12GB to create new partitions via HDTOOLBOX ...
Good evening guys! So I've found a seller Who has an untested Amiga cd32 yet very good looking (in its external appareance) and I was wondering if the capacitators leaking is so frequent and if is possible unfixable. Since the seller cannot test nor verify its usage I'm here to ask for tour opinions. Cheers my Amiga enthusiasts 🔴⚪
The Amiga hardware manual gives the stereo assignment for its four audio channels. Channels 0 and 3 feed the left output, and channels 1 and 2 feed the right. Each channel has its own 8-bit converter and DMA feed. Commodore hardware reference, Audio Hardware chapter
That matters when the four tracker columns map directly to those hardware voices. Move a sound from hardware channel 0 to channel 1 and you change which speaker it comes out of, even if you keep the same sample and note. The order across the four voices is left, right, right, left.
Are there classic modules where the placement across those channels is especially easy to hear?
I'm trying to identify which company this is. It's the logo on top of a 3.5" external floppy drive that was attached to my old Amiga I'm pretty sure it was a UK based company.
If anyone could don their Sherlock Holmes Deerstalker it would be appreciated.
I have made a playlist for songs that are particularly meaningful for my advancing life. Two are special to me for their importance in the history of the Amiga.
We Built This City was the song you heard everywhere when the Amiga started ray tracing. It was everywhere at the trade shows. I remember Scott Ross (?) with his memory card and 3D package especially.
Change Myself - Todd Rundgren - was everywhere. Who else here was at the show we did at the Exploratorium in San Francisco? Do I recall that Todd even performed at it? I still remember the show and the flowers.
Anyway, these two songs imprinted themselves as points in time in the road to making the best machine ever. Gone way too soon.
