Did you ever blow up an MSX or cartridge by inserting the cartridge after the beep?

My first SCC cartridge was already switched when I bought it. Though I've had some scary encounters. The first encounter was not as scary at the time because I was a kid who had no idea what he was doing while resetting his dad's VG 8235 by putting a pair of scissors in slot one... Not the most handy way to reset a computer (the reset button is just left to the slot and scissors have to be found first).
Later on when I had a Sony HB-F700P, an FM-PAC and a Philips Music Module, crap was just waiting to happen since the Philips beast is... well, a beast... It's too wide to accept anything in the slot next to it when it comes to the 700...
While hearing a buzzing noise from one of the speakers I had no clue what it was until I gave the Music Module a firm push... The noise was gone and adrenaline rushed through me... Back in the mid 90s those cartridges were mighty expensive and 17 year olds were not the richest people... Nothing got damaged...
I decided to cut a corner from the FM-PAC to let the Music Module not touch it anymore...

FiXato that's my vote but it's a mistake from my side due I read question too fast, I hope Jorito or someone fix it.

As someone who's done this a few times, I'm glad it's not commonly known to have destroyed SCC carts.

the 8235 also died of this cartridge inserting?

How do you know the NMS8220's problem was caused by incorrect cartridge insertion? I'm asking because I had the exact same problem with my 8220 but AFAIK that didn't occur directly following cartridge insertion.

I blew up the VPD of a NMS8220 as well by inserting a cartridge. Back then it was a repair (by Philips) of 100 Dutch guilders.

I inserted power up like 20x, but then nothing happened because I had Expert and they do have switcher on each slot preventing damage.

In my case it was the drive of a 8245. I inserted Salamander with the computer turned on and then turned on the light of the floppy drive. Thereafter, the drive motor did not return to work (in normal mode). By accessing the disk, turn on the light, but you could not access the disk.

I do not remember how or where, but I connected external power source to the unit and since then it works, but had to turn it off when not accessed the disk.

It's a kludge, I know, but at the time (I do not think I had more than 15 years, no internet and no information for repair), that was all I could get.

Ah, that's nice... Quibus! openMSX should support this (in catapult)

I remember my brother inserting Konami cartridges several times after beep and typing a Basic program to simulate a second Konami cartridge in the other slot to get the extra features. Fortunately our old NMS8220 still works perfectly.

I used to put the MSX in cload state, inserted, then cancelled the cload with ctrl+break.

Meits: It's supported by openMSX but not by Catapult indeed... (I think because Catapult was already not updated anymore after openMSX got the 'hot plug' feature.)
