My game Metro Wars for MSX2 ranked #14 out of 50 entries in the highly-competitive MSXdev'25 and I got a Moon Light Saga game as a prize 😃✌️ #retro #retrogaming #msx
I didn't have much time to look around but this is my Yesterday's catch. Three posters and a MSX game that I found mixed into a lot of Famicom games. #retro #retrogaming #rgf #rgfmini #retrogamefest
Ya listos en el Retrogamefest Mini 2026 #rgfmini #rgfmini2026 #retrogamefest 😃✌️
I got a nice looking Sigma C64 non-working. I discovered the PLA enabled all chips at the same time! The bus contention made chips really hot! I bought a replacement PLA and I had to change all the RAM chips for BASIC to work. Also repaired some broken lines for cartridge. #retro #retrogaming #c64
I finally tested my ECS Extended BASIC language with an Aquarius Data Recorder and a real cassette tape. It works just fine 😀✌️ #retro #retrogaming #mattel #intellivision
I've these in the collected volumes but always wanted to get the original magazines for these issues of Dr. Dobb's Journal. Steve Wozniak writing games and Landon Curt Noll (way before the IOCCC) announcing the discovery of the 26th Mersenne prime. #retro #magazines
I wanted the power led working in my Atari 600XL so I bought a new membrane from Retro Fuzion. The installation is relatively easy and now it works! The original membrane is oxidized. #retro #retrogaming #atari
Isn't it beautiful? Casio FX-750P programmable in BASIC language #retro #calculator
Cellphones from India for Mexico and someone supplies this cheap adapter. It works, but the metal softens along time and starts to deviate to the side and this happens. Lots of sparks, and it will blow your fuses. If you get one make sure it has retention pads at the top to avoid side movement.
Today is the MSX computers day. Let's put some MSX in action! #MaySiXth #retro #retrogaming #msx #msx2
I made a Motorola MC68000 processor tester just to make sure the ones I ordered from China were legit. Bus fixed to 0x4e60 (Move to USP). I couldn't use NOP 0x4e71 because it is odd and used for the reset vector. #retro #motorola #mc68000 #diy #electronics
I just put a hair band for the time counter to work. The original one become goo.
A few weeks ago I ordered an Aquarius Data Record because I never had tested my new ECS BASIC with cassette, and a few days ago I bought some Atari Mexican cassettes. Today, I received the recorder and I connected it to my PC and dump one of the cassettes. #retro #retrogaming #atari #cassette
After my previous attempt, I decided to apply hydrogen peroxide to my Atari 600XL and I managed to get the right tone this time. #retro #retrogaming #atari #atari8bit
For my first application of hydrogen peroxide, the bottom TI-99/4A (the one I changed the TMS9900) is now whitest than a nice one (top) 😅 and the keyboard couldn't be bothered, instead developed white streaks. You can see my old picture with the yellow tone #retro #retrogaming #ti994a
I was age 12 (circa 1990) when a local shop put up a pseudo-arcade Atari with B&W screen and a weird sea game. My only clue was the walking monster. 36 years later, I've found it: Crash Dive, and the bullets barely are seen, at the time I didn't knew why my ship exploded #retro #retrogaming #atari
My good friend Troy Schrapel sent me this from Australia. These Pico9918 replace the old TMS9928 video chips (TI994A, Colecovision, MSX, etc) and give HDMI/VGA output. The Pico PEB extends the TI994A with 32K RAM. emulated disk drives, and a ton of peripherals. #retro #retrogaming #ti994a #msx
I always wanted an #Atari 600XL, I got one in bad shape and shipping broke a corner. I cleaned it, and I got a black screen. Replaced DRAM and 74LS158, I got a BASIC screen for few secs. Testing cartridges I discovered it behaved better. I inserted DKJR 20 times and solved! #retro #retrogaming
I never have used a key holder, but I bought this, maybe I can start today 🤪✌️ #retro #retrogaming #donkeykong
I got another E.T. from the same vendor, and I discovered the cartridges and manuals were switched. Can you notice the 1986 copyright and the different windows on the spaceship? E.T was reedited! The original box looks silver, while the newest one is yellowish. #retro #retrogaming #atari
Crystal Castles rulezzzz. 2nd edition but still sealed #retro #retrogaming #atari
Ya estamos en Plaza Galerías Estrellas de 11am a 8pm. #retro #retrogaming #atari #Commodore #nes
I had loose cartridges for E.T and Snoopy, but this is my first time getting these complete-in-box for my collection #retro #retrogaming #atari
I'm going to have a table with retro systems this Saturday and Sunday. #retro #retrogaming
I disassembled the Atari 130XE keyboard. Can you see the broken lines? I got conductive adhesive from Amazon (very difficult to manage!) made a very botched repair, put the hair dryer, and corrected glued lines scratching with a screwdriver. It works! #retro #retrogaming #atari
The keyboard has some bad keys, and I think I can repair it. In the meanwhile I can play Borzork by yours truly using a joystick 😀 #retro #retrogaming #ti994a
