TensorFlow Lite for Microcontrollers is an open-source machine learning framework in which a TensorFlow model is built and trained on a host computer. That model is then reduced in size and computational complexity by an exporter that converts it to the TensorFlow Lite format. For the tiniest of compute platforms — microcontrollers — that model is then converted to a C array containing the model structure and any trained parameters, like weights and biases. On the microcontroller, an interpreter parses the C array to extract operations and data to run inferences against new input data.
Given that TF Lite for Microcontrollers runs on some heavily resource-constrained devices, I got to wondering whether or not I could run inferences against these models on a Commodore 64.
The Transactor was started life in 1978 as a Commodore Business Machines publication used to explain low level details of the Commodore PET. In 1982 it was reborn as a bimonthly independent magazine published out of Milton Ontario (Toronto) covering all 8bit Commodore’s. This revised magazine used the slogan new slogan was “The Tech News Journal for Commodore Computers” and was paid for through advertising and subscription prices. A quick scan of the covers below and you will be able to see when this change occurred. The Commodore Transactors were mass produced using a very inexpensive mimeograph technology while the independent magazine was created using a proper printing press.
Both publications were known for their depth. They covered hardware hacking in detail and were read by serious users. One issue even boasted that it was 95% advertising free right on the cover.
What can you do with Vision BASIC? Pretty much anything you want to. Speed will no longer be a problem! Why? Because on it's own, Vision BASIC is VERY fast! But when you need to crank out even more speed, all you need to do is insert machine language anywhere you wish to. Yes, you can actually type machine language instructions right next to BASIC commands! You won't need to load in external machine language files, and you won't need to poke machine language code to memory. This is because Vision BASIC also doubles as an assembler – you can write BASIC programs with it or machine language programs with it, or a blend of the two!
Vision BASIC also includes a whole new batch of commands to help you realize your programming dreams! Need sprites? Vision BASIC's got you covered! Need sound and graphics? Yep, gotcha covered there too! Vision BASIC was designed to greatly minimize your need to POKE around with all those crazy registers. In fact, you might never need to POKE again! And if you find yourself needing a command or function that isn't available, you can simply create it yourself – by creating the needed subroutine and calling it by whatever name you choose to give it. These "user defined" commands and functions can be saved into separate files and added to your programs whenever you need them!
PCBway community page for an adapter for a Commodore 1541-series disk drive. Makes it possible to add a parallel interface port to the drive for the purposes of disk ripping. Rather than cutting traces and soldering directly to a 6522 chip, it fits in between the chip and its socket. Add some ribbon cable and a DB-15 plug and there you go.
The picture is a helpful reference for how the IC socket and header bars are positioned.
Note that, per the response to my question:
Pins 9 and 10 are connected to pins 18 and 39 of 6522 - CB0 and CA1 (some count it from 1 so it's CB1 and CA2 then). They are needed only when drive is connected with C64 via userport to handshake while sending data. You don't need those for XUM1541/ZoomFloppy.
A collection of cartridges, adapters and replacements for the Commodore C64.
I offer the most common X cables that Joe Forster/STA lists on his site, not the X adapters as I have no ability to make the PC boards required. Special cables not listed below will be considered on a case by case basis and if I have the parts to build them.
The prices for the cables are in Canadian dollars and do not include shipping. The cable costs vary as each one contains different components and take different amounts of time to build. Shipping is typically $7 for one cable in a bubble-wrap envelope and multiple cables would mean a different shipping container and higher costs. Since I have no shopping basket, e-finance capability or ordering page, please email me with your orders. All of my cables are verified working under DOS, and are tested using various drives with the latest ROM versions and/or JiffyDOS.
The main goal of this project is to archive pristine versions of original Commodore 64 software, including copy protection. A secondary goal and benefit of this will be to catalog and document all the different copy protection methods used. This information will be used to improve emulation, as well as allow remastering of the software onto new disks for you to enjoy on the real thing.
Win 7/8/10, and Linux/i386/AMD64 kernel driver and development library to control serial CBM devices, such as the Commodore 1541 disk drive, connected to the PC's parallel port via a XM1541 or XA1541 cable. Fast disk copier included. Successor of cbm4linux. Also supports the XU1541 and the XUM1541 devices (a.k.a. "ZoomFloppy").
OpenCBM provides an interface to the Commodore IEC bus at the level of simple TALK and LISTEN commands, similar to the one provided by the Commodore kernel routines. Additionally, some higher and lower level bus control is available as well, allowing for full control of the bus.
The CBM serial devices are connected to the PC either to the parallel port via an XM1541 or XA1541 cable and, optionally, an XP1541 or XP1571 add-on cable. Alternatively, more modern USB cable solutions like XU1541 or XUM1541 (a.k.a. ZoomFloppy) are supported.
Any Linux, FreeBSD or MacOS X variant that support libusb-1.0 should be supported. Linux, FreeBSD and Mac OS X have been explicitly tested.

C64OS.com has grown from its original purpose as an outlet for me to blog about my adventures in learning to code in 6502 and my progress towards the development of a simple, single–tasking, event–driven operating system. It is growing into a resource for new and returning users of the Commodore 64 and 128 to find out about all the great new things being developed both in hardware and software. The aim of C64 OS is to work with the limitations of the Commodore 64 and enable it to become useful.
GeoRAM System 2.0 (64er Magazine - December 1992 Issue, Page 36) is a RAM Disk utility & machine code monitor for the Commodore 64. With this utility you can create a 2015 block storage device that can be used from BASIC 2.0.
After the program loads and runs, it will do a warm reboot. After the reboot, issue SYS 56832 to activate the software. The built-in help can be access by typing "HELP" at the > prompt
It is here you'll find all sorts of 3D printed parts for your Atari, Apple, Commodore 64/128, VIC-20, Amiga, Texas Instruments computers and other interesting applications.
