from 1541 Ultimate homepage:
It is about time to release some news about the 1541U-II. I think some of you must be really curious about the extra features and possibilities that the 1541U-II give, and about the progress on production and firmware. To start off with the 1541U-II features, I can tell you that it differs from the ‘standard’ 1541U Plus/Ethernet that:
- the board itself is about 30% smaller than the 1541U;
- it has a MicroSD connector, instead of a full-size SD;
- it has a real-time-clock function, for correct file time and date;
- it has a larger FPGA, which enables the implementation of more features;
- it has a USB Host port, which can be used to connect USB-sticks;
- it is targeted to have a suitable case for the device.
Some of you have written in the forums, that the MicroSD connector is not much of an improvement. But the rationale behind going to MicroSD is mainly the available space on the board is less, and that with the addition of a USB-A port, the average user will use the usb-stick rather than the SD-card.
So the MicroSD-card does not need to be removed from the cartridge very often. However, because at the moment that I announced the 1541U-II, the USB port was not yet tested, I could not reveal this feature as I did not want to make promises that I can’t keep.
The USB turns out to be quite a bit of work to get it to work, but I can now announce that I managed to implement enough of a host-controller function to be able to talk to USB devices and send the most basic commands to access a mass-storage device. I am quite close to have implemented the ‘read-block’ and ‘write-block’ functions, which is the interface level that the file system module uses. In other words, I expect to be able to access the (FAT) file-system on the USB stick quite soon!
How will it work for the user? My objective is to have one ‘directory’ level above the current root of the SD-card, where you can select which partition you want to browse. There the USB flash drive becomes visible, as well as the MicroSD card, if present.

EasyProg is a program for the C64. It is used to write (“burn”) cartridge image files (*.crt) onto an EasyFlash.
Changes:
- Workarounds for 1541U SD-IF bugs.
- Fix hex viewer, it got broken in 1.3

EasyProg is a program for the C64. It is used to write (“burn”) cartridge image files (*.crt) onto an EasyFlash.
Changes:
- Add flash driver infrastructure EasyAP (Makes it easy to support different flash memory types)
- Add “reset and start crt” and “reset and kill”
- Add BING! sound.
- Show all file types in directory list.
- Show directories first, followed by files.
- Internal directory parser tolerates some malformed directories.
- Still problems with 1541U.
- Show message when directory is too long.
- Torture test is more verbose now.

from Homepage:
EasyFlash is a cartridge for the C64 expansion port. In contrast to traditional cartridges, this one can be programmed directly from the C64.
You can easily create various classic computer game cartridges, program collections or even a diagnostic cartridge to track down issues with your hardware with it.
All what you need to do this is a C64, an EasyFlash, the software available here and an image of the cartridge (*.crt). As these CRT files may be quite large, a large disk drive like the FD-2000 or an sd2iec may be useful.
EasyFlash is not a freezer cartridge like the Final Cartridge III or the Retro Replay. And it’s no replacement for a 1541 disk drive like the sd2iec.

Aries was backordered on the required 24 and 28 pin headers needed to finish testing, and the order just came in this past week. Thus, I finally had a chance to solder and test the units. Testing went well, and I can program the units with my Willem programmer.
Originally designed to hold a 29EE512 64kB EEPROM, I found a good price on Atmel AT49F001 128kB 5V Flash, so I made the necessary adjustments and tested with the new memory. Testing went well, so I am releasing the design to production.
I have noticed one issue that I need to address. Some CBM units have an RFI shield that doubles as a heat shield. To perform the latter function, metal “fingers are stamped out of the shield that press on the top of the ICs. I need to ensure the metal shield/heat sink does not contact any of the pins on this unit.
