… or adventures of a lame modder
Yeah, I admit that I was super lazy for past few months if it is about writing posts. Thing is that material for future posts is being made in exponential rate so I have to do something about it. There is no better way than start posting all that gathered stuff.
This particular post is waiting in queue for almost a year and is still fresh if compared to other gathered stuff. Obviously, I’ll spare you another lengthy description of things that were already covered on this blog many times. Don’t expect stuff like C128 retr0brighting or other super-common topics.
Wanna become l33t in retr0brighting? then please read previous posts 🙂
The story began a long time ago when Wendell (cheers my friend) has ordered a modded C64 from me. Sometime later he’d asked me If I can refurb and deliver a few other machines. Two C128s were on that list too. He’d asked me to repair, refurb and add some mods to these Commodores – custom stuff! My fav! 😀
I wouldn’t be myself if I’d declined it. Moreover, I was like …
Finally, I could start to work on a C128 machine and I must point out that I’ve never had an opportunity to even see it, not talking about playing and modding it 🙂
I didn’t want to be cornered with one faulty machine so I’ve managed to win four auctions with C128s.
Unfortunately, all of the ordered machines didn’t work. It took a while to fix ’em all.
I’ve started off with fixing electronics.
After many hours spent on getting familiar with C128s circuits, I’ve figured that CHARROM is playing games with me. Since this particular motherboard had an already made (I think it is an original mod) mod accepting 28 pin EPROMs, I’ve decided to replace it with an overkill FlashROM -> W27C512. Overkill, just because I have plenty of 512s on the shelf 🙂
Next on a list was a dual OS ROM mod. Obviously, JiffyDOS is the first OS and stock OS as a second. I’ve bought all the needed files from guys running Retro Innovations and was ready to burn.
While working on electronics, I’ve also spent a while on refurbishing keyboards and cases. I’ll spare you another description of this boring process.
However, there is a one cool thing worth noting.
Keyboards had issues with broken … I’ll be honest, I’ve no idea how these are called in English… hammers?
Anyway, I’ve made a cool observation. The blue one is an original C128 ‘hammer’ and the black is from Amiga 500 keyboard. There is a slight difference. Black ‘hammer’ has an inside chamfer which makes is unusable unless …
Next task was to mount inside an SD2IEC mod with my own layout that I sell through store.retrohax.net
First I’ve picked a proper place to mount it in a way that allows easy and convenient access to SD card – right side of the upper part of a case
C=KEY – again from Retro Innovations.
A mod allowing to connect a PS/2 keyboard to a C128 (among other Commodores) in this case.
I’ve bought a DIY kit and below pic of an already assembled units.
I wanted to mount it on a metal cage in the middle of the motherboard.
The problem is that this mod cannot be mounted directly as in C128D or DCR because of surrounding components.
That creates another problem – lack of original and custom plugs used in internal C128 keyboard. I’ve figured that I can make my own out of 2.54mm gold pins.
…because at this very moment, I’ve realized that my wonder-socket won’t fit…
Awww yeah! SIDFX! A really nicely done mod. I was surprised when it came in.
Nice package, nice manual and the nice mod itself. Basically, it was a really easy job to mount SIDFX – Thank you SIDFX team for this extremely well-done project!
Hardware modding on these two C128s was ready.
However, I’ve also ordered one more thing for this setup.
It was a solution to address 80col mode and supports RGBi to S-Video conversion.
It is made by Pyrofer – a very cool guy that I’ve met on IRC – Cheers buddy 🙂
You can get one here.
Excellent piece of hardware I must admit and works like a charm.
I didn’t take any “after” pics but I have something better 🙂
A movie with all above working demoing two SIDs and PS/2 keyboard.
A small note though, that vertical bars are there because of my faulty plasma screen.
That’s it 🙂
Now you can safely watch a C128 80col demo!
