IIRC it was just two lines pulled to ground via resistors, shouldn't take much space.

Actually You can try to implement MC68030. These CPU are electrical compatible with MC68020, only socket and pinout are different. But it require PCB redesign, what may be problematic.

Perhaps in a future revision when the gerbers have been released

It's only a idea, not a request.

Without FastRAM and higher CPU frequency benefits over EC020 are close to nothing, and it's better to use turbo board with 030.

Meanwhile I found something interesting:
PIO2mod for A1200: http://leblogdecosmos.blogspot.com/
Maybe it will be worth to integrate.

There was some madman on AmiBay who hacked off the right hand side (next to mouse port) to make the board fit inside an A600 (and it did and worked).

Just saying, if the right hand bit was a connector of some sort this board would also be A600 case compatible :-)

A little insane but.....

Why putting an A1200 in an A600 case without having the extra keypad because only this can be done ??? Not everything what can be done makes sense. Second, we don't have new A600 cases. Finally, this doesn't make sense.

Got PCBs today. .working on it. with luck I might be able to try to turn it on today

tnt23 · 30 July 2018, 21:24

O.m.g.

PR77 · 30 July 2018, 22:39

Wow! Very impressive with the work! Fingers crossed it fires up without any smoke! Who manufactured the PCBs?

Chucky · 30 July 2018, 22:52

Well no short between power and ground so..

board done by JLCPCB

AJCopland · 31 July 2018, 11:28

omg Chucky that's amazing

fluffkitten · 31 July 2018, 12:11

That is just brilliant.

Chucky · 31 July 2018, 13:25

unfortunally no boot. cpu and budgie gets hot and there is issues with 12V and -12V within audio. soo guess quadruplechecking stuff wasn't enough OR I have some bridge. tiime to check even more

hard luck, good luck with next revision you can do this!

Amazing Work Chuckie. Looks amazing

Level 7 Int activation a little bit easier please. I'll be happy with the SVIDEO where RF used to be, Also is there going to be a toggle jumper to Set Amiga to permanent NTSC/PAL for the US/Japan crowd?

Chucky · 01 August 2018, 01:42

Composite,. Svideo.. NO RF. will simply not be supported. NTSC/PAL yes

Chucky · 01 August 2018, 20:36

Found a small bridge on budgie.. now I atleastget a sync on the monitor

Pffeww

RF is a prehistoric thing anyway.

Chucky · 02 August 2018, 01:17

YET a small bridge.. diagrom now boots with chipmem issues. the pads for the memory are SMALL (fixed in the file I will release) so it is HARD to solder the memory.. guess just a bad solderingpoint...

getting there!!
