Attic

You are in the attic.

The only way out is down through the hatch.

There is a load of old junk here. My first computer, based on a Motorola D-II kit, lies in a box as a heap of boards. It started with 256 bytes of RAM, and worked up to 12k; the hex display and keypad evolved to a 64*16 upper-case character display and QWERTY keyboard. This was real home-brew stuff, even some of the PCBs were homemade. Also here are a Dragon 32k, an Epson Z80 CP/M laptop (with external twin floppy drive) and early PC bits. Somewhere there's the remains of my twin-CPU SC/MP system. My Sinclair ZX80 has gone to a better home.

A cardboard box is full of valves (aka vacuum tubes), including a 2V directly heated triode with B4 base that must be much older than me. Valves were an important resource in the days when 17 of them could be got from an old TV in a jumble sale for about seven-and-six, but transistors cost half-a-crown each at least.
