TF1230 Beta Interest (Open Source)

[terriblefire]

Yeah we're working on getting it booting on all systems.. Putting IDE and burst back in wont take long.

OK interesting.. I got a board here for recap 1D.4

tested with TF1230 and got a guru.

as newer A1200 and ReAmiga 1200 have NO components put obn E125R, E125C, E123R, E123C I removed all those and then it worked fine..

checking where they end up. they go to NOTHING! they are basically (very) small antennas and nothing else. so commodore was right in their technotyes: those should be removed. not just the caps but the resistors aswell

Another machine. guru. had 3.0 roms. removed timing stuff. still guru.

put in 3.1 roms. all just fine.boots great

Just pullover E125R, E125C, E123R, E123C form 1d4 ofcourse
nothing that changed amiga still doesn't work on 3.1

In teresting. E121C and E122C should also not be populated. on my 1D.4 they are...
on reamgas not..

can you pleae test without them aswell CPUCLK and CPUCLK_A

[kulamario]

All components is pulled out
E121C and E122C 
As well

Ok so I solved my `Not Booting on 3.1 rom`

I tried all the suggestions as mentioned here by Chucky and still no joy but was getting a purple screen, and all the info on the interwebs points it to a ROM fault , but mine are orignal 3.1 so I thought must be good, anyways cut a long story short I tried an old pair of EPROM 3.1 roms and I got a partial boot ! hmmm but tried everything and stil no full booting but progress

So in the end I flashed the excellent USB Rom Emulators by CMORELY on here with 3.1 rom images and bingo ! worked out of the Trap !

So all I can say regarding this problem is perhaps our 30 year 3.1 roms are slowly dying , so please someone else try another set of 3.1 roms or burn a set to see if you get the same result
