⊳ Modifying a Sony Hitbit 10P to use a standard barrel jack power supply - 2022-03-13 07:37:39

Greetings everyone!

A couple of weeks ago I got a Sony HitBit 10p from a mechanical keyboard enthusiast from the University, a great guy :). He know where to leave MSX things. There was a particular issue: There was no power supply. After changing one power supply for a Sony HB-T7 I thought that it would not be much of a problem. And actually it was not!

I found a tutorial in spanish on how to do this with a phone charger. As you can see in the video, what he does is to use a soldering point below the switch connector to solder a 5v input.

⊳ How to config your Vortex Tracker for the MSX computers family - 2021-08-22 19:56:31

Hello my friends!

This is a reminder for me and for the future generations to come. I’m not going to show you anything very magical or new, but this happen to me and I didn’t have clue about it. So if you didn’t know, now you will!

Are you tired of compsing something in Vortex Tracker and hearing something odd when playing it in the machine? Your tracker might be wrongly configured!

So it seems that the truth is out about Bitlogic and the BAIXO Corporation.

Let me share it with you all:

⊳ Get the most out of MSXHub - 2019-10-12 14:48:22

In this post I’ll introduce MSXHub and how to use it in a very “linuxy” way just by organizing our packages a bit. You’ll need an MSX with MSX-DOS (probably in a flashcart) along with a network card and your fingers.

Introduction to MSXHub

MSXHub is a superb repository tool for our MSX Systems that allows us to download MSX software (tools, games…) directly from our MSX without needing a computer. We just need a UNAPI compatible network card and a flashcart to run the software over MSX-DOS.

⊳ Changing MSX HB-T7 Power Supply Unit - 2019-07-09 08:03:18

Hellllooooo everyone!

I’m alive, again. Maki asked me to make a blog post about how we changed the MSX HitBit T7 japanese power supply unit (from now on PSU) for a more modern and european one. So, let’s do this.

Update (2020-05-29): Victor Muñoz tutorial

Victor Muñoz followed this post (plus the discussion we have had on email) and did this mod. He has shared with me a PDF containing the tutorial he has made. So check this for additional notes and photos so it’s clearer.

⊳ Connecting to modern Instant Messaging services with an MSX - 2018-04-08 20:11:15

Hello!

It has been a while since the last post. Yes I’m alive.

So, in this post I will introduce you to two marvelous concepts:

BitlBee
IRC on an MSX with an TCP/IP UNAPI compatible network card.

Let’s begin…

Introduction

Why would you do that? I mean, there are more efficient ways to communicate with other people that require less effort, right?

Well, here are my two cents for the first point, BitlBee. BitlBee is a service that acts as a gateway for several instant messaging services, e.g. Facebook Messenger, Google Hangouts or Slack. Ok, but… a gateway to what? IRC, of course.

⊳ MSX2 Sony HB-F5: SCART to Japanese21 - 2017-09-30 18:10:15

We have adapted a standard European SCART cable to use it with an MSX2 HB-F5. You have to change the pins of one of the ends (the connector that will be on the MSX) as follows:

**SCART – Japanese21

** X means not connected.

1 – X
2 – 6
3 – X
4 – 3
5 – 8
6 – 2
7 – 20
8 – X
9 – 7
10 – X
11 – 19
12 – X
13 – 13
14 – 14
15 – 15
16 – 16
17 – 17
18 – 18
19 – X
20 – 10

WHILE - FOR:

We usually use B as counter. The main trick here is that DJNZ decrements the counter in B and then checks, so that you don’t need to do two operations.
