Smoke… again….

Yesterday I was building a Amiga to scart cable.
But when I was testing the cable, I had no picture on screen (only as shadow on a black screen).
So I looked on the internet and found that my TV (LG) must be manually changed to RGB mode.
So I turned on my Amiga and TV (cable disconnected) and while I was busy searching for the option, I hear the floppy drive running and noticed a funny smell…

I immediately look at my Amiga and noticed gray/white smoke rising from her.
So I turned her off.

It looks like R406 that started to smoke.
I have to find out what could cause this, and what I need to replace.

I killed a switch.

Last night I was working on a ZX spectrum keyboard replacement when a solder pad broke lose from the switch.
The switches are very tiny, the solder pad are even smaller, so the traces are to small to solder a wire to it.

Now I ordered a new batch of switches as I had just enough of them.
I hope that they will arrive soon.
sometimes it looks like an Asian is cycling to the Netherlands to deliver the package from China (it can take up to 6 or 7 weeks).

Found a music maker keyboard

Today, my lovely wife found a music maker keyboard at a second hand store.
So we paid the 1 Euro they asked, and I added it to my collection.

The keyboard came in it’s original box, but it has a big hole in it.
The keyboard is fine, but the tape with the program is missing,
Finding the program on the internet shouldn’t be a big problem.

New member to the family, A VIC-20

Today I collected a VIC-20.
I swapped 2 Commodore 64 computers for one VIC-20.
The VIC-20 is the predecessor of the Commodore 64.

The VIC-20 specs:
CPU MOS 6502 at 1 Mhz (1.108404 Mhz for PAL and 1.02 Mhz for NTSC)
20Kb ROM and 5Kb RAM (expandable to 32Kb)


I’m not sure what I’m going to do with it yet, it’s in working condition but I’m thinking about adding Jiffydos and a internal 32Kb ram.
