A600: Paula NMI Piggyback adapter

Hi my friends.

Recently I got a message from my friend highpuff that he created an NMI adapter for A1200 that piggybacks to Paula!
I was amazed since I didn't knew that the IPL0, IPL1 and IPL2 signals that were needed for NMI header were also available on Paula as well!

Yesterday I got a package on my mailbox out of the blue sky...

OMG, I was really happy that Highpuff sent me one kit for testing it on my beefy A600!
After all... Paula on A1200 and A600 are the same so why wouldn't it work?

Here's the adapter on it's full glory...

Really simple design but elegant and effective!
Time to remove my floppy dual drive combo, and plug the adapter to Paula.
Once it was ready, and switch was put in the adapter header it was time to give it a spin!

Hohohoho! After some custom kickstart fun, just pushing the button gives us HRTMon 2.36 (even from Early Startup Menu! Awesomeness!

For some people who will simple say... WTF is that, it's an Action Replay clone that can give some info and alter some address in RAM for hacking some stuff.

ACA630 had an NMI adapter by default that I showed in the past as well, but since Vampire doesn't have an NMI header the only solution to get the signals so far, was to get the signals from Vampire's Piggyback 68k socket (not something for the fainthearted doing).
Getting the header from another IC is a really awesome solution without affecting at all the rest of the setup. Good thing also is that the adapter is really low profile and doesn't mess with the height of the floppy drive (even my dual drive combo sat really well) and case closed just fine :)


Thanks a lot highpuff my friend... You rock!

A600: Ratte's auto switch working on my A600 beast :O

Hi peepz.

After finishing my Gotek inside my A600, something that troubled me a long time came in front.
I love my Vampire and RTG modes, but I also want native modes which atm I can get either from Indivision SD/FF or from RGB to Scart. Ofc both of these solutions require either a dual input monitor (HDMI/VGA or HDMI/Scart, which I already have) or having 2 monitors.

Since I was always fond of auto switch between RTG and Native I though... what the heck, I have to try Ratte's switch like I had in the past.
Worst thing, is that I would use the parallel port signal if I couldn't find one inside...
After talking with highpuff (ikod.se) who was making a batch on Amibay, I decided to gief it a go after he told me that U8 that I knew on A1200 was also present on A600! Dafuq I never thought they were alike sharing the same signals :)

This is the new switch that I received along with plenty of cabling in PRO quality! (Thanks a lot Claes mate, you rock \m/)

Ok Natives were ok as I knew that Indivision would run ok with Ratte's switch as I tried in the past Indivision AGA, 4000, mk2 without issues.

What about RTG coming through HDMI though :S
First of all HDMI is only digital while Ratte's switch works only with Analog signals.
Only choice I had was to get an cheapo HDMI to VGA adapter from eBay like this...

After making all the necessary connections to a spare recapped A600 mobo of mine... this was the result (btw, I asked highpuff to make me a custom male RTG cable in order to feed it directly to the HDMI adapter).

Result was SUCCESSFUL! OMG I couldn't believe it! Even putting SwitchControl in Startup-Sequence right before IPrefs gave me AUTO switching like it should!!!
After that I thought about dismantling the adapter to see how big it would be inside... Turns out it's rather slim

I couldn't leave the thick HDMI connector as it was would I?

One more test again and it was indeed successful as well! You can see in the following picture the U8 CIA adapter (what a PRO PCB man)

Here's a quick video about the booting and switching phases of RTG/Native using Ratte's switch on my A600.

Stay tuned :)
