libtrace – a library function tracer for FS-UAE

During development traces are a really helpful source of information when doing debugging or if you simply want to understand how a system works. When developing for the classic Amiga platform you learn a lot about the inner workings of applications if you could see what library functions they call and what parameters they pass . . . → Read More: libtrace – a library function tracer for FS-UAE

romdisk 0.1 released

romdisk

Recently, I was thinking about a minimal Amiga emulation setup that is required to run Exec and Dos from a Kickstart ROM image. Think of a reference platform for vamos. I soon came to the conclusion that all kinds of boot types result in accessing a device that provides the requested file system blocks. As . . . → Read More: romdisk 0.1 released

Amiga Parallel Port: How fast can you go?

In my plipbox project a fairly fast AVR 8-bit MCU with 16 MHz was connected to the Amiga’s parallel port to transfer incoming and outgoing IP packets from/to the attached Ethernet controller. A protocol on the parallel port was devised to quickly transmit the bytes in both directions. In version 0.6 a data rate of . . . → Read More: Amiga Parallel Port: How fast can you go?

A lua shell for FS-UAE

fs-uae-ctl-ui: FS-UAE Image Changer Utility

While FS-UAE recently added a scripting interface with a Lua scripting binding, it only provides capabilities to write scripts with hooks that will be called on certain emulator events. I hacked this scripting interface and added a Lua remote shell. With this shell you can connect while the emulator is running and issue commands. I . . . → Read More: A lua shell for FS-UAE

plipbox 0.6 released

It took quite a while to finish the release (over a year :)) but I think it was worth the wait:

A new parallel burst transfer mode was added that really improves the I/O speed on this Amiga port. You will get up to 235 KiB/s across the lines! Added new test modes for performance . . . → Read More: plipbox 0.6 released

plipbox 0.5 released

Release 0.5 of plipbox is now available and contains a software-only update that ships both a new Amiga plipbox.device driver and a new AVR firmware.

New features are:

Most important change is the handling of the MAC address. While in previous versions you had to set the correct MAC in both the Amiga driver and . . . → Read More: plipbox 0.5 released

Networking on the Minimig with PPP and Roadshow

TC64 with SilverSurfer attached to Raspi

When working with an Amiga running on a Minimig platform then data transfer is not as convenient as one might think: You have an SD Card connected and copying files around with SD Card is not the biggest deal, but unfortunately your Amiga is currently running from a system drive stored on this card :/ . . . → Read More: Networking on the Minimig with PPP and Roadshow

A clockport for Chameleon64’s Minimig

tc-cp

The Chameleon64 is a very powerful and versatile cartridge: Although its initially a C64 cartridge, it also runs standalone and allows to emulate different machines by replacing the FPGA programming. Today I use mine mainly as a HW Amiga emulator with the brilliant Minimig FPGA implementation.

If you look at the HW of the Chameleon . . . → Read More: A clockport for Chameleon64’s Minimig

Added SegTracker in FS-UAE’s Debugger

For most classic Amiga developers Michael Sinz’ Enforcer is a valuable tool for debugging. Especially the contained tools SegTracker and FindHit are very helpful when analyzing bugs in your compiled code: SegTracker patches AmigaDOS’ functions for loading and unloading binary files and then tracks where the (code/data/bss) segments of each binary are located in memory. . . . → Read More: Added SegTracker in FS-UAE’s Debugger

Building AROS hosted for Raspbian

The Raspberry Pi platform really looks very suitable for running AROS. I wanted to play with this setup and build a Raspbian (armhf) release from source (so I can hack on if I like to). I chose the Linux hosted version of AROS as it is already available in the source tree and Raspi’s Linux . . . → Read More: Building AROS hosted for Raspbian
