Allen Huffman    I did a thing. I wrote a BASIC program which will create 68 files named 0.TXT to 67.TXT . Each file is 2304 bytes so it takes up a full granule. (That is not really important. It just helps makes things obvious if you look at the disk with a hex editor and want to know [&]

Allen Huffman    The Micro Works Digisector DS-69 DS-68B digitizers were really cool tech in the 1980s. Looking back, I got to play with video digitizers, the Super Voice speech synthesizer that could sing , and even the E.A.R.S. electronic audio recognition system for voice commands. All of this on my Radio Shack...

Allen Huffman    Rules to the Challenge Vintage Computing Christmas Challenge 2025 Logiker The Pattern Observations I typed it up to figure out what the bit pattern would be. (Actually, I typed up a bit of it, then pasted that into Copilot and had it tell me the bit pattern.) . .------ - 2.- - --- [&]

Allen Huffman    A correction, and discovering the order RS-DOS writes things& A correction from part 2& This example program had BIN and ASC mixed up. 0 should represent BINary files, and 255 for ASCii files. I fixed it in line 920. (I will try to edit fix the original post when I get a moment.) 10 ’ FILEINFO...

Allen Huffman    The 2025 edition of the Logiker programming challenge has been announced via a YouTube video: This year’s pattern is a snowflake, and I am very curious to see the approaches people come up with in BASIC to do this. I have some ideas, but none of them seem small. This 19 19 image won’t fit on [&]

Allen Huffman    Obviously, things done today can be quite different than how things were done 30 years ago, especially in regards to computers. Is it strange that out of all the places I’ve worked where I wrote code that only one of them had an actual coding standard we had to follow? (And that was at a [&]

Allen Huffman    Step 1: Rename the .PIX file so it has the extension .data. This is needed for GIMP to recognize it as a raw data file. Step 2: Open this image in GIMP by expanding Select File Type and choosing Raw image data. That should allow the .data file to show up in the browser to [&]

Allen Huffman    Updates: To this date I still think one of the most useful products Sub-Etha Software ever created was MultiBoot. For CoCo hard drive users of the era, most of us had to boot from a floppy disk. That boot disk would contain the necessary drivers to access the hard drive. With boot files, one size ...

Allen Huffman    OS9Term was an RS-DOS terminal program written by Sub-Etha co-founder Terry S. Todd. It emulated the OS-9 text screen control codes. This not only included things like color, move cursor position, and underline, but also the overlay windows OS-9 Level 2 windows on the text screen were all created...

Allen Huffman    I am writing this so one of the 6809 experts who reads this can chime in and tell me a better way& Often I post things so they can get in the search engines in case anyone else looks for that topic later. This is one of those. Using DEF USR is a great way [&]
