 Just taken the plunge and bought a plus4!

As per the title, I decided to add a plus 4 to my 264 collection, it came with all manuals and over 20 games 2 joysticks, scart lead, psu, tape deck etc, it is also recapped and heatsinks fitted.
It works a treat and it is great to play Icicle Works, Treasure Island and Saboteur not to mention all the other classics.
My question to the wider community is- how reliable is a recapped and hestsinked Plus4 given that the machine without these adjustments is considered to be a ticking time bomb generally- particularly when compared with the C16.

A non ticking time bomb!

I think next to the overheating ICs, the joystick issue is the second biggest threat to the 264 series.
Try not using more advanced joystick models, especially: never use autofire
This function causing short circuited TED, and will kill it in no time. Valid to C16 too.

There was a circuit developped some years ago to protect the TED in this conditon from joysticks, but I am not aware of any working prototype.

If I remember well, the Plus/4's extra ROMs also tend to use more current and generate more heat, than if EPROM versions of them would be used (IC swapping). Maybe I am wrong...

I think from PSU side Plus/4 is much more reliable than the too weakly designed C16 PSU, so when I count the Plus//4s' overheated CPU and extra ROMs VS C16 PSU, the risks are somehow balanced.
(TED is DEAD is the same risk for both models)

Thankyou for your detailed response to my question, I will take your points into consideration. The machine is in good working order and the psu is in fine form and I would like to do all I can to keep it that way so any tips on how to maintain and look after my plus4 are gratefully received!

The seller provided a helpful list of do's and dont's regarding the leads and the connecting of said leads - like not connecting or disconnecting anything when the power is on- joysticks TV cables etc.

Wow I did not know that an auto fire joystick could damage the TED chip. Dam I love using my Quickshot 2 turbo joysticks on the Plus4 .

Hi,
there is a very detailed discussion on that joystick matter, lot of useful info from others and some usual offtopic BS from my side ,

Worth to check it.
