Just in time for the new 68k build of AROS!


I'm seriously considering getting one of these to hack AROS 68k on.

I've looked at these before. The Coldfire is a really bad fit for Amiga... Ok we can now build AROS for the coldfire, so we can get AmigaOS functionality, but that doesn't magically make Amiga programs coldfire capable... There is a really good link on the Coldire wiki page that lists the differences between the coldfire and the 68k... It's pretty horrific... Coldfire software should run on a 68k, the reverse isn't true :(


Getting it running on these boards would be my first priority,  68k binary compatibility would come much later, if at all.

When you take into consideration that i've not written a line of 68k assembly for nigh on 15 years it would take quite a long time indeed! :)

68K compatibility on coldfire has improved in more recent cores, but you are still left with trap-and-emulate for various operations. Not sure what happened to those instructions where they were implemented but with different behaviour to the 68K; they were the real killer.


The ACP guys are more qualified than I am to answer that. They've obviously come up with some way around it though. Quite what compatibility issues and/or performance hit their solution entails I'm not sure.

I was thinking I should learn VHDL or Verilog or something too. When you think of all those "I wish I had XYZ for my old machine" moments...

My word this looks sexy!

All those years of PL-SQL and Turbo Pascal are flooding back to me.

Ada is nice! :)

Don't be so sure, the interwebs are a positive haven from the torment of the real world... but I bring it upon myself as someone not necessarily wishing to conform. :)


Not wishing to conform probably explains why I'm a minority within a minority within a minority. ;)

I'm making up the verb from the adjective:


Ham-fisting, in Karlos-speak is to perform any action "in a manner that lacks dexterity or elegance, clumsily"... Not to fist someone with a Ham...


Who knows what sort of thing they get up to in "that London"?

On a more related note,  I've dug out my RKRM's and various 68k books to get the old synapses firing in nostalgia mode.

AROS 68k source here we come.

This VHDL stuff is looking very tempting though, anyone suggest a first-timers FPGA kit to buy or perhaps shuld I just get one of MikeJ's boards?

Well, that's the point of AROS! Shame others don't get get stuck in and have some fun!

I think MikeJ's board is probably the best option... that way, if you find yourself totally stumped and bored with VHDL... at least you will have a new Amiga... :)


There's some real hardcore Amiga coders (68k and C) on this site and I personally a couple of them.  As you say it's a crying shame they haven't helped out so far. :(

Being under NDA/no-compete from certain PPC dedicated software houses might be the problem though.

MikeJ's board does look rather tempting, moe tempting than a MorphOS licence key for my Christmas pressie (If you are reading this love!)

IMO it would be better to get the fpgaarcade board, not only it is cheaper, but anything meaningful you achieve could be tested by others people.


I'm sold. :)
