Starting Msx Assembly 4

Published at October 22, 2020 ·  9 min read

So lets start where we ended in part 3. We had a piece of code which printed a letter, one by one, to the screen to finally print “Hello world”.

Execute:
        LD HL, HELLO

LOOP:   LD A, (HL)
        CP 0
        RET Z
        CALL CHPUT
        INC HL
        JP LOOP	
HELLO:  db "Hello world",0

First we point register pair HL to the label HELLO. On that label we define a set of bytes (db) in memory, “Hello world”. Effectively, HL now contains the memory adress of the capital H. INC HL will increase HL so it will point to the next byte in memory, containing the letter e. Now what will happen if we use INC (HL) instead?

Moved Server

When you are reading this, this website is no longer served from my own personal server. I’ve been running my own servers for years, but I didn’t feel like keeping the server up to date, configure it for email etc.

So I moved my domain, bosselaar.net, to Google. My email is now hosted by Google G Suite and this website is now running on Google Firebase. Time to remove my VPS.

Moving was quite straightforward, although the email migration took quite a bit longer then I expected. My mailbox size is about 5GB but it took a couple of days before the migration tool copied all my email over to G Suite. And my own private server was not the bottleneck ;) After the mail was migrated it was just a matter of pointing the MX records to the Google ones and new mail arrived in Gmail.

Time Flies

What a year it has been…

The last 12 months have flown by and no update on this site, so time to change chat.

It’s been a bit over a year now since I lost my brother and a bit over 2 since I lost my father. Most of the time things are going fine and I’m usually a cheerful guy but sometimes the emotions still hit me and it can cost a lot of energy. And the corona thing is also not really helping ;) . Anyway, expect some updates (soonish).
