Shown here, a software engineer at Roklan spends his evening doing a build and test of GORF for the Intellivision, to be sold by CBS Electronics.

The purpose of the piece is to visually show the process of assembling the software into its final form, in real time.

For the first time in more than 40 years, we are able to see the ATARI CAMAC Cross Assembler working in an emulated Data General MV/8000 environment, where we assemble a copy of DIG-DUG on a machine with a faster processor, and much more resources than an ATARI 800.

We are working on a version for the ZX Spectrum that connects via the expansion bus.

This work is part of a much larger push to create a generic bus interface.

If you can help, please join the discord. :)

FujiNet is a multi-function network adapter. It was initially developed for the Atari 8-bit systems, but we started adapting its firmware, and building other hardware versions for other platforms.

To date, we have implementations for Atari 8-bit, Coleco Adam, Apple // and ///, TRS-80 Color Computer, Atari Lynx, Atari 2600, Commodore (64/128/Plus4/VIC20). There are also system bring-ups happening for many other computers, such as ZX Spectrum, IBM PC (ISA and RS232 versions), RC-2014, BBC Micro, and more.

It provides virtual disk, for loading software from the Internet, a virtual printer which rasterizes to PDF, a network adapter with tons of protocol offloading, and a whole host of other subdevices (e.g. CP/M emulation, speech synthesizer, and more)

It is a public project, that anyone can jump in and hack on, and we want people to come in and help hack on versions for their favorite systems.

This video shows off what became of Island Graphics ProPaint, for the Commodore Amiga. The Professional version of Commodore GraphiCraft. It became Aegis Images. It has some unique features that paint programs like Deluxe Paint doesn't have. Enjoy with Vaporwave soundtrack + slight glitches in video.

As the speaker in question here, I wish to reply.

I am formally apologizing for minimizing the question. It was not my intention to be derogatory.

But to formally address your question:

The same issues that affect any FujiNet device, are the exact same which affect any IoT device. The problem sets are one and the same, and are addressed by a combination of disciplined test driven development (which we are now doing), and auditing (which we need people to help with.), as well as leveraging fixes from the upstream vendor framework (ESP-IDF).

Since this issue is very close to your heart, would you like to help address this issue directly? All of the issues that the FujiNet team addresses are a direct result of champions who drive them forward.

Thank you for your time, Thomas Cherryhomes, Firmware Engineer, The FujiNet Team.

In this #retrocomputing #archaeology series video, we show how the tools at #ATARI coin-op worked, in-context. We modify Centipede, assemble, link, and create new EPROMs with our changes.

This video shows the process of doing gamedev using other, larger systems to develop software for the Atari 2600 and 5200 game consoles using a cross assembler. This example contrasts a cross assembler from Sorcim running on Atari8bit and S-100 hardware. Enjoy.

After many weeks of work, I've now released a comprehensive deep dive into video the ColecoVision Adam Computer. It is not meant to be watched all the way through, but rather used as a reference for those interested in seeing the Coleco Adam in context.

I needed an extremely simple battery meter for my minimal Arch Linux X11 environment on my Thinkpad T61, so I wrote one in raw Xlib.

Were some games for the #ColecoVision written in #Pascal? Instead of speculation, Let's validate this assertion by using a quick tool I wrote to check for calls to the #Pascal routines documented in the Programmers Guide and OS Listing.

tschak | 3 years ago | on: Composing a song in the first Amiga Tracker (SoundTracker 1.21)

Ever wanted to see how the very first Amiga tracker worked? I am spending a chunk of my Friday (starting 10am CST) putting together a cover of Gazuzu's "Go Go Gorilla" (1983).

The system itself is an emulated Amiga 500 running WorkBench 1.2 in WinUAE, using a copy of The Ultimate Soundtracker version 1.21.

The resulting track will then be upconverted using NoiseTracker, while also updating the effect commands, to be able to save a MOD version of the song, that can be downloaded.

tschak | 3 years ago | on: UA 571-C Remote Sentry Display Program from Aliens Resurrected

Well, I had to test the development environment, somehow!

(apologies for the audio, new filter chain, and I only had time to record this ONCE)

As part of @tr1nitr0n and myself rebuilding the GRiD Development Environment from batches of GRiD server hard drives, I needed something to test that the development environment that could compile Pascal, PL/M, Fortran, C and Assembler was working as expected. Then I thought about the sentry remote weapon system scenes that were cut from the theatrical release of James Cameron's Aliens (1986) film, which used GRiD Compass II 1129 laptops. GRiD had developed a set of working displays in GRiDBASIC for the film. These were never released, but now that the same tools are working again, I recreated them.
