I got to the bottom of the “PRINT ERROR”; it thought that it had a serial port attached and tried to talk to it. I’ve currently set that so that it looks like the chip is missing, which has got rid of the error. I *might* do something with it later on. I’ve re-designed a […]
Oh, and I added scanlines.
I spent a few hours this morning porting the 6502 emulation code across and loading in the EPROMs. There was quite a bit of refactoring and optimisation, after which I was pleasantly surprised to see this happen… I’m not sure what the “PRINT ERROR” is for, but it worked!
I’ve started getting the display emulation working first, as this, along with the sound emulation are the biggest unknowns to me. I’m using C and SDL, which seems to be pretty straightforward to use. The Standard Microtan 65 Display The basic Microtan 65 board had a 32×16 character display which could show the standard ASCII […]
Remember the Microtan 65? It was my very first computer, and I have fond memories of tinkering with it. A couple of decades ago, I developed a Windows emulator for this classic machine.

I recently had the urge to have a go at making a cover of the excellent Airwolf TV series theme tune. I used to watch the programme when I was a kid and loved both it and the music. So, I had a go at a version of the theme tune from memory. I now […]
Although I live pretty much in the middle of a forest, most of it is plantation and is mainly long straight rows of pine trees. There are little pockets of wildness dotted about, but most of that is just densely packed thin spindly little things and not very photogenic. Yesterday on my walk with the […]
One of my favourite pieces of music is Tangerine Dream’s White Eagle/Girl on the Stair and I decided to have a go at making a cover version of it, and here it is… White Eagle Cover
I’ve still not been able to get out with the camera much this year. So, I thought I’d revisit some of my photos from my visit to the Lake District last year. The first one was a photo that I took last year in the Lake District which I’d initially rejected because roughly a quarter […]
