I know I’m being very repetitious on this subject. But SDLTRS is supposed to read WAV files. Which TRS80GP cannot. So I was trying to reduce a conversion step in the hope that one less step might help my odds of reading a tape file. So, I tried to read the WAV file created by …

Yahtzee best load yet
It goes bad after this! BTW: I don’t remember how to play. I wish I added the date to the comments. I assume it was 1980 or soon thereafter. No sooner than I post the above…then I get this, although this is a different version. A screenshot wasn’t big enough to show so much. I …
Perhaps a better cassette player?
To recover old TRS-80 tapes. I saw this on Amazon. I don’t think QFX is known as a great brand however it does have adjustments for Bass, Middle and Treble. The question is, do these equalizer settings get transferred to the USB device or are they only for playback? Also the volume on the far …
Some other TRS-80 programs
Prime numbers. To do 1000 it took 2min 28sec. In turbo mode about 25 sec. You can tell I was a computer student. I found some convert to hex and binary programs.
My TRS-80 Bowling Score program
Well I was able to retrieve my TRS-80 bowling score program. It was the last file in a multi file wav download. Strangely enough I was successful by adjusting the volume. In a previous volume setting I was able to get a good load of the first few programs…but not the bowling program. Then I …
I Found my TRS-80 Yahtzee game
I found my TRS-80 yahtzee game. Well at least on one tape. And so far unsuccessful recovering it. But why are the first few lines always readable? Then it turns to crap! There were also multiple versions on the same tape. Below…The 1st two screen shots are the same program (the 1st file on tape) …
Created/uploaded a video about recovering old TRS-80 cassettes
I was so excited that this worked, that I had to make a YouTube howto video.
My cassette player arrived today for my TRS-80 project
I recently talked about this project here. When I first read in an old TRS-80 tape, today, in Audacity (using this new player) I noticed the high’s and lows were getting chopped off so I immediately lowered the cassette player volume. Here is how the volume looked in audacity, after I adjusted the volume lower. …

What was possible on our DEC PDP-11/70?
For my first “real” computer job, I sought after work on a DEC PDP11. Hopefully using RSTS/E. And luckily that’s what I got. The company had a DEC PDP 11/70 running RSTS/E. They also had a Data General Nova 3, running BLIS/COBOL (an OS written in COBOL). I knew nothing about the DG, as we …
Successful RSX11M COBOL
You are supposed to type COBOL to compile. But COBOL didn’t work. So I found C81.CMD on a DU1: directory listing. Glad the compile included the link, because my link wasn’t working DU1:[005004]LINK. Below was before I renamed HELLO2 to WORLD BTW. This is the command file… So, actually, the C81.CMD file includes C81 and …
