I'm glad to hear it!

I'm actually having some unresolved technical difficulties with that one at the moment, so it's good that you'll be trying it on a known working keyboard.

People still use the IRC, maybe it's just the American time zones died off for a bit…

Come back, guys. sad

Yeah, if you could find generic multi-cables that have both the DMG and CGB head and a full pinout, that would be the primo keyboard cable for sure.

I bet you are going to mop the floor, dude.

I've been listening to your soundcloud for like a week straight. heart heart heart

I had three DMG-07s and decided against using them, because I really hate destroying rarer hardware.

Also, these link cables are cheaper and you get two adapters/keyboard cables out of one.

None of that is to disqualify your input, which is certainly valid. What was the debate? I'm not sure why the re-pinning method wouldn't work… it's not like the fifth (ground) contact in the DMG-07 cable actually goes to anything inside the keyboard when you use one of those instead.

As for the jeweler's screwdriver thing, the smallest ones I have a 1.2mm diameter flatheads, and they were still too big to depress this style of pin on each side. hmm

I also felt that my early keyboard woes were to blame on the adaption of PS/2 to DMG link port.
Don't worry though I feel your pain man. Still trying to get a any keyboard (Mostly the #70009 as its been verified functional by Vex) to sync with PS/2 socket.

For the record, I think I'm the only other person who has been using an Inland #70009, because it was literally the cheapest PS/2 keyboard I could get. I don't think Vex has used one. I apologize if I played any part in creating confusion about that.

That said, I can't think of a conceivable reason why one PS/2 keyboard would work and another wouldn't – the entire point of a standardized bus is universal compatibility. I mean, if they all varied that greatly in clock timing, then they wouldn't work on every computer that uses PS/2 keyboards, would they?

I'm also not a programmer, and don't know anything about how LSDj handles keyboard input. So, if by some dumb luck I picked a PS/2 keyboard that is different in some undocumented way from almost every other PS/2 keyboard, that'd be pretty crappy. I really hope that isn't the case.

I guess the quick way I could find out would be to open it up again and solder my re-pinned DMG-04 cable straight into the keyboard, but I'd really rather just get my adapter working.

On the upside, that PS/2 port Justin put in your DMG is fresh as hell – it looks so clean! Major props!

Also, thanks for compiling all of that information about the keyboard interface. I've been crawling google for a few weeks now and haven't found information that detailed.

Hi,
well, it has been broken to and from. There are no real guarantees that it will work since the code is a hack that seems to work mostly… but I would not be surprised if some keyboards have timings that dont work. You could try for example 4.1.0 or 4.6.4…  or maybe really old versions as well…

This question and all of its potential answers will go way over my head, but has anyone figured out what the "acceptable range" for keyboard timings would be? I seriously doubt anything like that has been done. I'll play with some different versions, perhaps.

Well, I finally got that pin situation figured out on the other end of that cable.

From what I can tell, the two slots on the top of the cable body are accesses for a pair of microtweezers to spring the barbs that keep it captive in the plug body. So, instead of pressing them out with a jewelers screwdriver, one would ideally use a pair of tweezers smaller than I have to squeeze the two sides of the pin – I ended up using bent staples. Really.

When I got it out, I took another picture to illustrate what I mean:

By the time I finally got this one out of there, I'd bent the pin in such a way that it wouldn't spring back and stay in the new slot. I had to carefully bend the barbs that hold it in place back out a wee bit, and then it stayed in its new slot.

So, there you have it: One weird hardware variation on the DMG-04 Link Cable. Modders Beware!

The keyboard is fine – the adapter I just finished is the likely culprit.

Is there any kind of obvious indicator that LSDj recognizes the keyboard it's synced to?

Yeah, that adapter I just finished didn't work. I checked the pinout that I set up and it's all accurate, to my understanding.

I wish I had more experience, so I'd know what an appropriate response from the keyboard and the game boy would be. The keyboard LEDs should light up on boot, right? Should I get any response from LSDj that says it recognized the keyboard?

This is my first LSDj keyboard interface project, so I've got some troubleshooting ahead of me…

Thanks for your interest, everyone. As I've said, when I work out kinks, I'll get back to you.

EDIT: Is there a documented problem with LSDj 4.6.3 and the keyboard interface? I might have just taken apart a working adapter over a software problem, hahaha.

I'm really interested in this. Even if it is a bit pricey. http://www.asmretro.com/product/ps-2-to-gameboy-adapter

I'm one solder away from finishing one of those.

Let me tell you, they are a bitch to make, and going rate in a used game store for a DMG link cable is $7 (here in Austin, at least). So, the raw materials themselves come to five or six bucks each at retail. It's not a bad deal at all.

actually, ive been really thinking about getting an LSDJ keyboard and the specs on this looks pretty good. id be down to commission one for ~$40? i would even be down with a similar color scheme. PM if you are interested.

Sweet. I'll get in touch with you in a bit when I've tested mine more and feel like I can provide a truly high-quality product.

Wow dude, those are all sick!

What all have you changed on the Kaossilator, and what does it do?

I feel you, dude. I've been putting off a craigslist ad selling bike parts from when I was a racer for far too long. sad

Greetings,

My name is T, and I've been an alcoholic for three years.

Really though, my name is Cameron, and I'm an Austin native who's been into the chip/demoscene community for a few years now. I believe my first big experience was Datapop 2009 during SXSW? Man, it's been a while…

Anyway, I've been an avid listener for years, but just recently committed enough to buy dedicated hardware (flash carts), and start refurbishing my equipment—I bought a bunch of broken DMGs on clearance over the years and I've just about finished repairing most of them. I've never felt adequate as a musician, and it's actually a huge personal insecurity I'll have to deal with sooner or later—that's why it's taken me so long to get this involved. I'm a lot better with computers and electronics than I am with music, so maybe I can overcompensate my way into musicianship. tongue

The Austin scene is small now, and mostly overlaps with our larger noise music scene. Hopefully I can reacquaint myself with the people I've met over the years (or you lovely new people) and we can start putting together dedicated chip shows again.

So, after finishing my LSDj Keyboard the other week, I've embarked on my quest to build PS/2 to DMG adapters, which is relatively simple in theory. I chose to use DMG-04 cables and to swap the pins using Trash80's method.

However, when I got my cable apart, I found something anomalous:

As you can see, these don't match the plug body and pin design from the DMG-04 used in Trash80's demonstration.

Anyway, I've managed to complete one of these, but I'm having a lot of trouble getting the pin to release on the second (the other end of the same cable). I had to cut part of the plastic bridge over the pin slots away to even be able to depress the pins.

This raises some questions:

  • Has anyone else encountered this DMG-04 hardware variation before?

  • If so, what were your experiences?

  • How the fuck do I get this pin out?!
