A New Motherboard for Amiga, the Platform That Refuses to Die

I'm feeling a little dense - but what's the point of this?

I get it's a new board, you can take your chips off your old board and now put them on your new board (which is broken down into component boards).

i.e. My understanding is that you could take your existing A1200 and put a new board in the case, move your chips to the new board... and you'll have something that acts like your A1200... The thing you started with..

My best guess from reading 2-links down is that the selling point is that you now have modularity. Purpose of this project is that subsequent work can replace sub-sections of the A1200 with something more modern (for example HDMI-out as mentioned below) - but if you did this (replaced all the daughterboards with upgraded versions) it wouldn't be an A1200 any more..

just generally confused

Wouldn't a FPGA approach be the way to go, if that's what you want?

Not necessarily, FPGA cores are not faithful reproductions of the Amiga custom chips.

I think the main premise here is that the Amiga custom chips can, with proper care, last for a lifetime or more, but the Amiga PCBs (some of which are 30+ years old now) only get brittle with time. Capacitors leak, traces are damaged/corroded, pins on headers break etc. People attempting repairs with substandard equipment/training also exasperate this issue by damaging the (limited) supply of original PCBs even more.

A new PCB solves this issue and also provides modularity for future extensions. At the end, it’s still an Amiga, behaving exactly like an original Amiga would.

Thanks, you're right, I was being dense.

My feeble mind can accept that it's just a replacement board, you can host all your existing chips on.

A1200 boards are over 25 years old. A lot of the boards are damaged because of capacitors leaking, just being old. Many of us that still use the Amigas like using "proper hardware". I like the idea of taking a 25 year old computer and hacking the machine to play DOOM or going on IRC or even checking my emails.

FPGAs have been used for Amiga Accelerators the fastest accelerator (at present) is the Apollo Vampire V2.

Here is a complete rundown of the accelerator:

The point is fun of pointless tinkering in the shed. As someone mentioned in HAD comments this thing doesnt have decoupling, bypassing, impedance matching, nothing, its just someone playing with electronics in his spare time for fun.

This is pretty cool. If he adds an RTG board with HDMI then I will buy it!

Check this out then - http://www.majsta.com

a new implementation of Amiga with insane specs.

"Your [sic] coming from a site that we don't like."

Well, gosh.

To anyone confused, when you click the link in the GP, the website just displays a message "Your coming from a site we don't like", and redirects you back to the hacker news homepage.

I wonder why they don't like us...

EDIT: I'm an idiot, name, not url.

The word 'hacker' in the name probably.

Poor grammar, inability to serve SSL.

The Vampire is FPGA-based which means they are emulating the chipset (AGA in the works) and the CPU (they came up with their own version of m68k and named it 68080).

It’s impressive but it’s not a traditional Amiga. It also has compatibility problems.

Yes, thanks. I have seen it. Looking for more of a real version of the original HW with some "tweets". I want to put this in my A1200 breadbox. I have done the same thing with a C64.

The need for alternative/open platforms grows daily.

Heck, the number of alternative and open platforms grows daily.

That follows logically from the GP's comment.

Big fan of alternative OSes. I would add the word: viable to alternative/open platforms.

In lots of use cases this just means a modern, up-to-date, browser. Firefox OS had the potential to become instantly viable but Mozilla (I feel) was working with blinders on.

Haiku and ReactOS are at the cusp. ArcaOS (the latest OS/2 incarnation) would be jaw-dropping exciting if somehow (not likely) they went Open Source.

Aside from the major commercial players, distroLinux and the BSDs... I don't see lots of viability out there (sadly). Maybe Android x86 (though it's frustrating to use as a Desktop OS)...?

RedoxOS might become interesting as it's written in a new, memory-safe language. Although it's not quite clear if that language and RedoxOS itself can handle the security challenges...

FirefoxOS was eye opening when I picked up one of the cheap $40 ZTE phones they were promoting with it. It ran extremely well on the bottom of the barrel SOCs vs similarly spec'd android phones. I was sad to see it gone so quickly.

I remember Amigas were still sold in specialty independent stores in the late 90's.
