When I arrived in Brest at the end of 1982, I had only the first computer that I bought in Halifax, Nova Scotia, in 1980.
I was using it on the ship I was posted on and at home too. And I was programming it with the Pascal compiler that I had created.

Commodore 64 Portable (SX-64)

In 1983 in Brest, I bought my second computer, a Commodore 64 Portable (SX-64).
Although it was a "portable" computer, it was rather heavy: 10.5 kg (23lb). But it had everything: small display, keyboard, CPU, a memory 0f 64 Kbytes, and one floppy disk drive.

My goal was to port my Pascal compiler to the Commodore 64.

In a small computer shop, I had met a young man, whose name I don't remember. He owned himself a Commodore 64, and he agrees to work with me to port the compiler.

The microprocessor was an 8-bit MOS Technology 6510 microprocessor, a close derivative of the 6502 from the same company.
So, it was completely different from the Intel 8080 or the Zylog Z80.

Although the Commodore 64 had 64K of RAM, the upper 20K were shadowed by a ROM that contained the BASIC interpreter and Kernal. So, to access the full 64K of memory, you had to swap out this ROM, and when you wanted to use the Kernal, you had to swap back in the ROM.

We managed to create a small operating system that roughly emulated CP/M, the operating system of my first compiler, to port my Pascal compiler in its both modes and to write a 6502 assembler and disassembler.

I never sold all this, but I think I gave it away to most people who asked for it.

I cannot remember exactly what happened later to my Commodore 64 Portable. I believe that at some point it broke down and I threw it away.

Amstrad CPC 464

On the Cybèle, I bought another microcomputer, an Amstrad CPC 464. It was to stay on the ship and to be used by the officers and myself.

I mostly bought it to play video games.

I remember that I play for many hours a game whose name I cannot recall, where the goal was to escape from prison.

When I finished the game, I was disappointed that there was no more challenge. I don't like a game that finished, I much prefer never-ending games.
