Glad you found a way to convert files ... I used to have 2-3 KC87 programs on my smartphone for testing purposes 10+ years ago I wanted to look for a few days ago, but forgot :/ I think I used a Win 3.11 tool back then.
Yeah, I found a Windows program that was a bit flaky on Win10 (not updated for some time), but the Perl script worked a treat ... of course, I guess if it's a standard TAP file then any converter should handle it ... ?
I'll have a look at the schematic. On this page ... www.sax.de/~zander/z9001/bw.html ... there is an excellent functional description "Funktionsbeschreibung" which has the RESET logic described in Section 3.2 - we know that pressing the [RESET] button increases brightness, so this would be my starting point: "The RESET logic is implemented by two DL123 (1A) monoflops. The first monoflop is started after the voltage is switched on by the RC combination at the B input and delivers a pulse of approx. 10 ms in length. The trailing edge of this pulse starts the second monoflop, which forms the actual RESET pulse of 5 µs. The pulse duration of the first monoflop is dimensioned in such a way that it is guaranteed that all voltages have reached their setpoint before the pulse expires. The RESET button only affects the second monoflop."
How fascinating. Thanks, noted. From ChatGPT: The German words **"Sie"** and **"sie"** are distinguished by capitalization and context, as they have different meanings and uses: ### **1. "Sie" (capitalized):** - **Formal "you":** Used to address someone formally, whether singular or plural. It's commonly used in professional settings, with strangers, or to show respect. - **Example (singular):** *Haben Sie die Rechnung bekommen?* *(Did you receive the invoice?)* - **Example (plural):** *Können Sie uns helfen?* *(Can you help us?)* ### **2. "sie" (lowercase):** - **She:** Refers to a singular female subject. - **Example:** *Sie ist Lehrerin.* *(She is a teacher.)* - **They:** Refers to a plural subject (any group of people or things). - **Example:** *Sie spielen Fußball.* *(They are playing soccer.)* ### How to Distinguish: - **Capitalization:** In written German, "Sie" (formal "you") is always capitalized, even if it doesn't begin a sentence. - **Context:** The meaning of "sie" as "she" or "they" depends on the verb conjugation: - Singular (she): Verb is conjugated in third person singular (*sie ist* - she is). - Plural (they): Verb is conjugated in third person plural (*sie sind* - they are). **Quick tip:** Pay attention to the verb form and context to determine the correct meaning!

It came out looking great, and good to see it loading software!
Re-uploaded, apologies, forgot a small section on making the cassette cable
I still trust you that you'll fix the original power supply!
Bluetack to the rescue! :)
... and Dads!
Awesome Video !

Schwierigkeit is difficulty off the top of my head... Oh somehow didn't notice your subtitles (-:
I'll be sure to add a warning next time to get your attention 😌
The screen brightness thing may be due to the capacitors reforming or just being weak, I think.
I'll have a look at the schematic. On this page ...

Okay ... ??
Sie w/ capital S is you, not they. sie lowercase is they.

From ChatGPT:
The German words **"Sie"** and **"sie"** are distinguished by capitalization and context, as they have different meanings and uses:
### **1. "Sie" (capitalized):**
- **Formal "you":** Used to address someone formally, whether singular or plural. It's commonly used in professional settings, with strangers, or to show respect.
- **Example (singular):**
*Haben Sie die Rechnung bekommen?*
*(Did you receive the invoice?)*
- **Example (plural):**
*Können Sie uns helfen?*
*(Can you help us?)*
### **2. "sie" (lowercase):**
- **She:** Refers to a singular female subject.
- **Example:**
*Sie ist Lehrerin.*
*(She is a teacher.)*
- **They:** Refers to a plural subject (any group of people or things).
- **Example:**
*Sie spielen Fußball.*
*(They are playing soccer.)*
### How to Distinguish:
- **Capitalization:** In written German, "Sie" (formal "you") is always capitalized, even if it doesn't begin a sentence.
- **Context:** The meaning of "sie" as "she" or "they" depends on the verb conjugation:
- Singular (she): Verb is conjugated in third person singular (*sie ist* - she is).
- Plural (they): Verb is conjugated in third person plural (*sie sind* - they are).
**Quick tip:** Pay attention to the verb form and context to determine the correct meaning!
