Now be honest. Is there anyone aged between 35 and 55 in the UK who hasn’t used a BBC micro? This little machine was massive over here. They were everywhere, Rugged, dependable, terrific BASIC interpreter, in-line assembler. The list goes on and on.
This machine came to me from my friend Tris. He is another retro-computer collector but unlike most of us, knows when enough is enough and decided the his BBC Master would be enough and gave me this non-functioning unit.
Under the lid.
The machine has an Issue 4 mother board. I think this is a bit unusual. From memory I think Issue 3 and Issue 7 were the most numerous. Another thing it has is a lid lined with aluminium foil. Curious. I wonder if it gave out too much interference for the TV or somesuch.
When power is applied, I here one beep. There should be two. With a monitor connected there is a nice raster on the screen and a flashing cursor. Nothing more.
A look inside shows that the keyboard connector is very tired, with a number of connections broken. I tried to reconnect the broken ones. There was a brief bit of activity as the words “BBC Micro…” started appearing on the screen. _VERY_ Slowly. I tried a reset and things got worse. The beep didn’t end.
Now I’ve seen that the machine is close to working and so my strategy is this.
- Replace the keyboard cable – I have one on order.
- Replace the capacitors in the power supply – It won’t hurt.
- Re-asses the situation.
