“Microsoft has open-sourced the version of BASIC it created in 1976 for the #MOS #6502 processor used in many early #microcomputers.

As the software colossus explained in a Wednesday post, Microsoft founders Bill Gates and Paul Allen wrote the company’s first product, BASIC for the #Altair8800 #microcomputer and the #Intel8080 #processor that powered it, in 1975.

A year later Gates and Ric Weiland, Microsoft’s second employee, ported Microsoft #BASIC to the #6502Processor.

In 1977, #CommodoreComputer licensed it for $25,000 and used #Microsoft #BASIC in its #PET, #VIC20, and #Commodore64 machines.”

Mein erstes Spiel in MOS6510-Assembler aus dem Jahre 1988...FlinFlon entstand im Jahre 1988 und ist ein aufgepimptes Pong für 2 Spieler. Das Spiel wurde damals wegen dem etwas "veralteten" Spielprinzips vom Markt&Technik-Verlag abgelehnt. Nichtsdestotrotz landete das Spiel 2005 auf einer Go64!-Disk...

Design an test of PHASE OUT LPE levels with my self-developed level editor (C#.NET) direkt in the Vice emulator. The latest editor version supports saving level data in the cloudbased database via webservices.

The C16 is cleaned and reassembled. Not pictured is the filthy Datasette that will be restored at a later date. I haven't installed the diode to allow it to work yet anyway. I'll probably pop that in when I upgrade the RAM.

This was such a satisfying repair. The machine had a blown fuse and a dead CPU. I'm just happy the TED chip was not destroyed as that would have been harder/more expensive to work around.

A Commodore 16 computer sits on a green cutting mat. The "Commodore 16 User Manual" is on top of the computer. There is a joystick and a monitor with the "Commodore Basic" screen on it.A before picture of the Commodore 16 when I got it. Quite dusty and dirty.

Last night I spent some time building an adapter to connect the C64 6510 CPU to the C16. I burnt a modified KERNAL ROM image from Andy @ hackjunk.com and was surprised to see I still couldn't access my Pi1541.

Silly me naïvely didn't follow the wiring diagrams for the CPU adapter and just sort of wired the external registers with a "near enough is good enough" approach, P0 to P0, P1 to P1 etc. A couple of the registers are actually supposed to be swapped over.

After correcting my mistake, the C16 boots! I've given the case a wash and pulled the keycaps off. The keyboard fully works but it is filthy.

To do:
Clean keycaps and reassemble case
Install diode for cassette motor line
Look into modding to increase RAM to 64k
Clean and repair datasette and joystick

A messy wooden workbench with hand tools, a cathode ray oscilloscope, crt monitor and a Commodore 16 motherboard with keyboard. The computer is working with a game called "Burger King" on the screen.

Back in 2021..my first self-developed logic game PHASE OUT for the Commodore 64 was realeased in 2014 by RGCD and Psytronik. After this time I made some bug fixes and created new level packs for the game. For my self-publishing I used new cover plastic sleeves with printed paper inserts and put the game on 5 1/4-inch floppy disks...

The keyboard is dusty, but all the keys work! The left and right cursor keys were missing their springs for some reason, bit I found some similarly sized ones.

The circuit board from a Commodore 16 sits on a green cutting mat on a bench. There are wires and tools scattered arround on the bench. A computer monitor displays a "hello world" BASIC program.

Perfect to „showcase“ my C64-Boards.

„Case“ is done by Plexilaser and badge, once more, from Retrobadgeman.

Ideal um meine C64-Boards zu präsentieren.
