Love that detail... !!

I’ll take 100 of each chips when available.

[kipper2k]

I cannot and daren't give an availability date. Parts are available and ordering batches will be kept small . I won't comment too much on the coding side of the house except to say that a fair bit of the legwork has already been done but all the desired features are going to complicate the process. The BGA soldering "appears" to be good, time will tell as the chip is tiny and 0.5mm was no fun trying to get a board manufactured that can do the edge, a lot of trial, error and cost

Sidenote: I will never use PCBWAY for manufacture and projects, their prices for 5 boards are just extreme

Just sos everyone’s knows me better I’m an Amiga Fanny boy from way back. I buy all the goodies for my Miggys. But I’m nots, I repeat I’m nots Dommy, stop spreading big big lies!

I don't know that Doomy was ever on this forum, Thank God!

Kipper can you at least assure us whether these replacement chips step boards will be astrospec, or at least milspec? At the minimum, superspec at least?

Not sure as to what you are actually referring to ?

LOL, kind of happy I am not the only one wondering what that means...

Suuure.

Classic link thanks, even as a former owner of Amiga.org I never read through that gem. Doomy has had lots of crazy threads on Amiga forums over the years.

I can guarantee the PCB is made to military spec.

[grelbfarlk]

Well that's a relief. Are you going to pay the £30 to mark it with The Definite Mark of Excellence from CAGA?

No, but we will get each board Knighted.

[grelbfarlk]

What if... -and I don't know how many LE's this would need- but you could include a basic phylactery in silicon, so if the board ever died it could become like un-deaded?

[Pyromania]

Will these new Amiga custom chips be military spec?

[QuikSanz]

Well, they appear to be conformal coated so close enough.

A few years ago we were making a 'jig' at work and decided to use an Arduino to speed up prototyping it. It didn't work too well -- the constant insertion was ESD hell and the boards didn't make it a week. I found out about this very cool board called the Ruggeduino and among other things it puts a 220-ohm fuse and 5.1V Zener on each and every pin and that's on top of the AVR's impressive 5V design and ESD tolerance. They never failed.

And yet it's still not close to military spec.

Could we make these boards mil-spec? No. Not even 'industrial spec.' Nope, not going to happen. I don't think Lattice even makes a mil-spec FPGA.

Though I was surprised to learn that there are mil-spec FPGA out there. Actel makes some mil-spec FPGA (IGLOO and ProASIC3) based on flash technology. You can get a 12K part for the low-low price of $178 right now. Mil-spec is not cheap.

Fun fact, the ProASIC3 is also a 5V tolerant FPGA and is still being made today. Actually, I don't know why people seem to think this is super rare and opt for level shifters all the time. They even make 100, 144 and 208-pin QFP for hobbyists who are BGA-shy.

Heck, real 5V FPGA are still being made. I mean, here is one, honest to god, real 5V FPGA. Not "5V tolerant", real 5V supply and 5V CMOS pins.

Microchip even makes ones with the AVR built-in. So yeah, 5V isn't dead, you just need to look around.

[Promilus]

Well it is all about technology used by FPGA and complexity of logic. ProASIC3 is 130nm part while iirc Cyclone 10GX is 20nm part. One would expect something like TG68 to work better on 20nm part with level shifters. Cyclone V is 28nm, Cyclone 10 LP series is 60nm. Stratix10 is 14nm. On the other hand things like Agnus can be implemented more naturally with those low-density 5V FPGAs or even CPLD.

[Pyromania]

I pitched the idea of these replacement chips being military spec because imagine the marketing power of having Doomy onboard promoting and evangelizing this new development. No marketing budget can match the pure emotionally charged endorsement of Doomaster himself promoting this idea and I suspect he will also buy these chips and insert them in old rusted A2000's that somehow end up for sale on eBay. Even McBills verbal valuation of 100 million dollars in the early 2000s to DiscreetFX Partners for the price of buying Amiga Inc. pales in comparison to the value of a Doomaster product endorsement.
