Will take a look myself later... Would it be possible to one-file them, or do a d64, in order to try them on real hardware? Hello Orion70, how does one d64 a tap file? Let me know and I can do that. Also, I've tested all the games I attached and they work fine on my Vic, I just had to use a Tapuino...

The only way to prevent this from happening is putting extra diodes into the keyboard (which wasnt done in the vic20 and c64 to reduce cost). [... so] all you need to do is connect the diodes to make it work[?]. To decouple the matrix, each key contact needs to have a diode put in series, on the ke...

Very intresting, do we have perhaps another working link of it? The video is loosing the connection over and over

Hi necronom, reset button always good idea. Red marks on your pic is showing a connection from pin 1 (GROUND) to pin 3 (RESET), so it's showing right. Some attention should be paid to pin 2 (+ 5V max. 100 mA // References: Programmieranleitung C64 - user port pinning seams vic 20 compatible). Keep a...

It doesn't seem to behave well on my (NTSC) VIC 20 - the screen is offset to the bottom right to the point that the bottom few pixel rows aren't on my monitor and the farmer disappears when he gets close to the right side of the screen, only to reappear when he gets caught by a chicken. [...] Check...

Ciao fr.,
Dipende cosa vuio raggiungere. Il cassette buffer é perfetto per corti programmi max. 204 Bytes.
Pure utilizzabile é l'area @ 02A7-02FF dec. 679- 767. Entrambe aree non bisognano die essere dichiararti al basic.
A presto

Very interesting reading. I will check this asap on my home made paddles.

So this would mean that if you build a keyboard yourself, all you need to do is connect the diodes to make it work.
What kind of diodes would it have to be?

Interesting found. Maybe rare piece, never seen before. Seems US stuff only. I could't find anything too either https://www.google.com/url?sa=t&source=web&rct=j&url=https://opencorporates.com/companies/us_ks/0702530&ved=2ahUKEwjQwsiBhM_yAhUz_7sIHePVDJwQFnoECBQQAQ&usg=AOvVaw0KV91B...

...However, I am curious what the problem was, if anyone has any input! I guess the loader ran out of memory. Starting at 4609, with Sys 4880 remains 271 bytes free for basic. In addition the machine code program must be protected, lowering basic room with, for example Starting with Run 80 80 Poke ...

I gave a hint some time ago, if you really want to find out then use $900D instead.

I've found a solution where my hands stay clean. Fax paper roll. It no longer matters how good the ribbon is. Maybe not good for business, but for some listing dumps IMO OK. The fixation of the bracket is a bit tricky, but doable. Look that. Is not the on original MPS801 but compatible SP-180VC. WP_...

Good idea. It could also be about demos, ones with unusual graphics and sound effects, in my opinion there are too few for our brave MHz ace machine
