Nice!  I wonder about performance - i.e., weren't the original ROM's something like 160 or 200ns?  Wonder if the bus can support anything faster?  :lol:

Doesn't matter if the chip is rated faster.  Whatever clock is used is the speed the data is doled out.

So, even if the chip is rated at 50ns, if the buss and clock speed is 100ns, the speed is 100ns.

I may have that backwards, but a faster chip won't matter!  :confused:

I want this! Will be so much easier to try out my custom kickst on my Amigas, no more burning new ROM's left and right, just power off and plugin a programmer and done! Also two is great when testing modifications.

This will sell like hot cakes :)

I wouldn't mind to have one of these "kickflash" if it used 2MB flash instead so I could use a 1MB rom with Poseidon/PFS/updated graphics.library/updated icon.library/updated exec.library/68060.library/updated scsi.device/fat95... I'd like to boot with less resets due to loading rom modules and also to be able to easily interchange data even if my HD dies.

Well, in fact 1MB would be enough as long as I could use original roms (as emergency and for re-programming) and the complete megabyte for a single rom. I won't boot my 1200 with kickstart 1.3

This would be a better product if it contained several megabytes, maybe even a couple dozen to allow storage of any stock or custom ROMs that may be wanted. With simple logic and r/w settings allowing a software switch to list and or choose the desired ROMs.

So this does not allow you to write to the roms from software need hardware ?

is it not like that zorro thing , what am i thinking of ?

 That is what it says.
 
 However it should be possible to modify your motherboard to allow writing to the flash chip. At the very least you'd need to hook up a write strobe from the cpu to the flash chip, because by default the kickstart socket doesn't have any way of signalling a write.
 
 You might want to put in a "write protect" switch so that software couldn't accidentally (or deliberately) rewrite your kickstart without you realising. It's easier safer to require you to remove the rom and put it in a programmer.
 
 I'm not that jazzed about the optical sensor. I preferred the ctrl amiga amiga for 10 seconds switching that I had on my old (unfortunately dead) kickstart switcher. I don't know how that worked as there is no reset line to the roms either, it possibly just monitored the address bus???

Hopefully he sorts out the mentioned licencing and gets the product rolling.  I designed and produced a similar tidy solution around 6 years ago (see attached) which was aimed as a simple flash based ROM replacement for anything A500 upwards.  The ROM modules were intended to be sold blank, so avoiding issues of needing licences for the product; and programmed using a purpose built low cost programmer connected to the Amiga parallel port.  I also developed all the Amiga software for controlling the programmer, which included facilities for manipulating ROM data (odd/even split/combine, verification, etc) and other fancy features.

Unfortunately I'm an electronics engineer; I'm not into retail supply, so needed someone else to do sales.  It was all rather disappointing after talking to a number of Amiga retailers who were all keen to know more, then sending away a number of free samples, only to never hear anything back.  Even a simple "sorry, not interested" would have been fine, or at least some kind of response to repeated follow ups.

And that was that....

That truly looks amazing, Anthony.  It is sad no one ever got back to you; perhaps with the renewed interest within the community there might be someone to take your project on.

You would think this would be the sort of thing amigaKit would pick up

@Castellen

You could have tried to open your own micro business from a web site without investing much. Then if it doesn't work it doesn't. With a degree and some good skills you probably could expand it to other stuff later and grow a bit, and then grow more later... And then.. Ah forget it:)

Yeah, you would.

Jens walked away from his completed design while the Amiga rights were still in circulation. Nobody has offered any similar device (no, that wossname thing that is some kind of early boot does not count).
Not until private persons havr been able to design and build these themselves has there been any movement. And _still_ no reaction from any commercial entities. You really have to wonder why.

Is there some kind of secret handshake among the last sellers of things Amiga to not do any unit that could be set up to be sold with an unlicensed Kickstart rom in it???
