It's been some years now that I got my Intellivision. I own only 5 game cartridges and have been dreaming of a multicart ever since. But I wasn't willing to buy the RTO for over € 100. Now I've built a PiRTO II. That's a cheap and simple project based on PI Pico. Happy! 🤩

I've bought some old literature! First edition in German from 1982. For a long time I was wondering if I would like this classic. And if I should read the English original or the German translation. When it turned up for cheap I thought I'll give it a try now.

Title of the German translation of Tracy Kidder's 'The Soul of a New Machine'.
It's about two hardware development teams at Data General around 1980.

This one was released in 1982 in German. The English original came out in 1981.

Long persistence green phosphor is a thing of beauty. The deep green color can't properly be captured by the camera. The slow fade of the image when it changes is magical.

I only have very few games cartridges and it's not easy to find other games for a reasonable price in Germany. Apart from the 2 player sports games I don't like that is... But at least I have some of the other great classics like Frogger and Q*Bert! 😍

This is my entire games collection for the Intellivision: Burgertime, Space Armada, Frogger, Tennis, Q*Bert, Poker & Blackjack...

From time to time you have to get things from your collection out and try if they still work! This time I took my Intellivision. Still working fine what a relief! 🤩 Especially as I want to build a Pico based multicart for it in the near future.

One of the quirkiest controllers of all times. The directional disc actually has a total of 16 digital directions.

Burgertime is in my opinion the best arcade port of the console

It's not that common to see 2 Mega 65 and 2 Apple IIc at the same event here in Germany!

A Mega 65. Modern FPGA implementation of an expanded Commodore C65. There's a small business card standing on it telling about Retronetzwerk Nord, the retro community of northern Germany.

Dirk's Apple IIc is a bit yellowed. It's a north American version with QWERTY keyboard and NTSC composite output. A SmartPortSD device is connected to it.

That's my Apple IIc. A German version with QWERTZ keyboard and monochrome PAL composite output. In order to get colour out of it there is an RGBtoHDMI connected to the expansion port. Also running a SmartPortSD.

For the Bubble Bobble highscore competition you had to play it on 3 different computers. The Commodore C128 (in C64 mode), the Commodore Amiga and the Atari ST. Incidentally all those came to the market in 1985. That's 'XL' years ago.

Interface XL Doesn't stand for extra large interface, but for the 40th 'Interface' retrocomputing event that happened yesterday in Klausdorf near Kiel, Germany! Mostly four times a year happening since around 2013. Couldn't find out exactly. More photos coming up...

Group photos of yesterday's attendees. Some of those have been there from the beginning. As usual it's a bunch of old guys.

There was a Bubble Bobble highscore competition. You could win an ArcadeR joystick for example.

How did the SmartPortSD project go on? Well, in the end I made two of them. Had a wrong firmware on the Arduino at first. Took some time to diagnose. Then I had to print my own DB19 plug because a standard one won't fit the Apple.

Two SmartPortSD devices. One in a white 3D printed case and one in a black one.

Oddly enough there were a lot of MSX machines on display...

The event was themed 'emulation on vintage and modern computers'. So I showed my emulation work horse from back then, the Atari ST. Got some emulators running on it: Spectre Macintosh emu, TRS-80 emu, ZX Spectrum emu and PC Ditto software emulation of an XT class PC...

'Manic Miner' works just fine on ZX Spectrum emu. Even in monochrome high res.

PC Ditto is emulating an XT class PC on an 8 MHz 68000 machine. That's impressive in one way and very slow in another. Good for running text mode software, but much too slow for games. 1987 Spectrum Holobyte's Tetris in CGA took literally minutes just to drop one tetramino.

February has begun and this ISA month with no less than 3 retro events for me. Started already at the 'connected' in Uetersen, Germany, yesterday. Pictures following...

I sat down to try to record a video tonight but I just can't get into the right frame of mind. My mind just keeps going back to the millions of marginalized people who are on edge and scared about the future.

With the MSX Pico the computer starts directly into the menu screen of the cartridge without going into that Sony menu before. And it runs both games perfectly fine from there! I'm quite happy now! 🤩

While I can start Burgertime by exiting out of SofaRun and using the command line tool ODO, that doesn't work with Godzilla Balls either...

Oliver Klink (kolli) @kolliretro.bsky.social · 16/01/2025

The boot process takes relatively long. And there are at least two ROMs that should be able to run on my machine but SofaRun can't handle them: Burgertime and the modern homebrew Godzilla Balls...

Using the SD512 my Sony HitBit 75D will always start with it's internal menu. Requiring you to go down to 'BASIC' with the cursor keys and after pressing Enter the machine will boot up with the Nextor DOS into SofaRun, a ROM launcher application...

New hardware has arrived! I've bought an MSX Pico! I already had another flash media solution before. But the SD512 has issues that the MSX Pico doesn't have...

Two SD card based storage solutions for the MSX. The SD512 from 8bits4ever in the back and the MSX Pico by Jeroen Taverne in front both come as cartridges.

I was at the monthly Atari meeting at Elmshorn, Germany, today but didn't take any pictures. While it was a nice event there was really nothing very interesting to see for me. But of course I won't let you down. My friend Frank generously allowed me to use some of his photos!

3D printer action going on. For one the screws M2.5x24 for the RGBtoHDMI case arrived. And then I printed a case for the ULIfAC. That's a multi purpose floppy emu, RAM expansion thingy for the Amstrad/Schneider CPC a friend gifted to me. Haven't yet tested, but at least it's in a case now... 😉

... after some detailing with a file and some sandpaper it fitted perfectly. Glued it with superglue to the DragonMMC case. Seems to be sturdy enough. Happy! 🤩

Test fitting it to the underside of the DragonMMC case (into the recess I mentioned earlier)

Glued in place with superglue and DragonMMC inserted into cartridge slot of Dragon 32. Looks neat!

...so I guess it's up to me making something! And that's with me being a total noob in 3D construction and CAD software. 😱 Actually after watching a tutorial I managed to build something with FreeCAD and slice it with Cura! 🤩

Screenshot of FreeCAD showing my little object. It's basically a rectangular case with one side open.

After saving it in STL format and loading it in Ultimaker Cura I was able to slice it for printing on my Ender-3 S1.

Oliver Klink (kolli) @kolliretro.bsky.social · 02/01/2025

The DragonMMC has a lot of overhang and there are buttons to press half way out. I thought that a little support would be good. There's already a recessed area on the underside as if it was meant to have a stand there. But nothing came in the package with the STL files...

And while the 3D printer was already running I've printed a case for the RGBtoHDMI that I use with my Apple IIc too... Now I have to wait for the screws to arrive. Don't know about you, but M2.5x24 are not a size I have in stock... (Size due to screw holes in PI Zero.)

Oliver Klink (kolli) @kolliretro.bsky.social · 29/12/2024

Bottom part of the case for the DragonMMC ready. Top has to wait a few days.

3D printer doing it's job. I've already shown you my new DragonMMC SD card device for the Dragon 32 and now it needs a case. Luckily the STL file was already available, as I'm no good in modeling 3D parts.

In 1994, a math professor discovered that Intel's Pentium chip sometimes gave the wrong answer when dividing. Fixing this "FDIV" bug cost Intel $475 million. I analyzed the Pentium chip and found the bug. 1/N

It's time for the Grand Unification. 🖖 I have 5 Zx Spectrum +2s one of which is an eBay rescue that I haven't even opened yet. I've been prepping for this for a while and the plan is to bring them all up to the same spec with upgrades and fixes. I apologise in advance for the thread length.🙂

I've made myself a somewhat early Xmas present and bought a DragonMMC for my Dragon 32. Other option would have been CoCoSDC, but that wasn't available in the EU and more expensive as well. I'm pretty happy now! 🤩 Just have to 3D print a case later.
