It has been in a bin liner in the garage for the last 20 years so I was expecting the worst.
It was pretty dirty and the external drive had rust on it. The power supply looked like it has seen better days too.
I opened it up and cleaned it up. So much dust had built up in there.
Looking much cleaner inside and out
The 512k expansion looks to have survived pretty well.
After cleaning I tried to power it up and hey presto
Even the floppy games I had stored seem to load although I had no sound. Could well be a sound chip problem but I will look into that when I get my decent RGB cable sent from ebay
Overall I'm just happy it powered up after all this time
