What do other people use for connecting the Oric video output to HDMI? I'm using something custom, constructed by joining two other devices together 😂

tbh, the output isn't perfect but it works. I feel like there must be a better option.

I probably could have tidied up the Cumulus cable a bit, but with the LOCI, it is so compact, self contained and easy to use out of the box.

I'm sure I'll be tempted to get the Oric out a lot more now.

One thing I like very much about the LOCI is how small and self contained it is. The device I had previously was always a bit fiddly to use.

Now that I've got the Oric Atmos working with the LOCI, it's time to try out the new Encounter release by @dbug.defence-force.org. Old school retro adventure with amazing graphics. I love it!

With the firmware now up to date, it is time to try loading tape files again. This time it is working, e.g. the Stormlord tape loads, as shown below. The Hobbit also loaded.

My first few attempts at loading a tape file didn't work, so I thought it was time to upgrade the firmware. The update process was trivial and appears to have worked without issue. The versions have indeed changed in the LOCI UI from what was shown in my earlier photo.

Loading from disk appears to work fine, with the few demos that I have tried so far.

I'm about to try out the LOCI for the first time with one of my Oric Atmos machines. Let's see what this thing can do! First check, the red button brings up the LOCI UI. Looking good so far.

During development of the game, I drew the rooms out in a notebook. The floor plan is actually based on a real building called "The Solitude", built by John Penn in the 1780s, now part of the Philadelphia Zoo.

I thought I'd try out my 2022 js13kgames entry "I've Been Ghosting" in the browser app on my Samsung TV. Turns out it works quite well.

A few years ago, I was busy attempting to reverse-engineer the schematic of the Commodore VIC 20's 6561 video chip from a photo of the silicon die. I mostly finished that effort and produced the image below of the silicon die showing the functional blocks labelled.

The programmer's manual is a bit used, as I certainly used it a lot back then. I wrote a tool to convert Visual Composer ROL music files to the Sierra On-Line AGI game sound format, for fan game creators to use.

I also have the books for the Composition Projects and Jukebox. #AdLib #SierraOnline

Brings back memories. I ordered mine from Sierra On-Line. I don't have the Adlib card itself anymore but I still have all the books. #AdLib

Ever wondered what a point and click adventure game might look like if emojis were used to create the scenes?

Well, it looks different depending on what platform and OS version you are using. Mac v Win11.

The following is a screenshot of my circuitverse.org SAA5050 simulation being used to render a full Teletext page. I had to break it up into multiple smaller screens due to the max size limitation of Circuitverse's screen component. #Teletext #SAA5050

For those who really love the early history of Sierra On-Line, here is a digital scan of the invite to Ken & Roberta Williams's housewarming party at this very house on the 3rd Sept 1983. 200 guests received this invite. #SierraOnline #KenWilliams #RobertaWilliams

The house includes a racquetball court. Ken Williams was a big Apple II fan and expert in those early years. Not surprisingly then, he had an apple computer logo built into the floor of the racquetball court. #KenWilliams #SierraOnline #appleII #appleiie

The stained glass windows either side of the front door, showing characters from Sierra On-Line's 1983 "The Dark Crystal" hi-res adventure game, are simply amazing!! #thedarkcrystal #SierraOnline
