The Commodore 64 EasyFlash Cartridge

With some money I had left in my PayPal account, I decided to buy one of the EasyFlash programmable cartridges for the Commodore 64 from Sinchai.de

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. For smaller drives EasySplit can be used to compress and split large cartridge images.

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.

Did you have a Commodore 64 when it was released 30 years ago? Do you still have it? Do you still use it?

It would be great to hear your memories of this brilliant 8 bit computer. Please leave a comment below, and I will compile them all together at the end of this week. If you wish, you can also email me at andy@retrocomputers.eu

I look forward to hearing your stories!

Happy birthday to the Commodore 64 – 30 years young.

Taken from the excellent article at The Register : The Commodore 64 is 30

Commodore took the wraps off the Commodore 64, one of two immediate follow-ups to its popular Vic-20 home computer, 30 years ago this week.

The 64 made its public debut at the Consumer Electronics Show (CES), though it wouldn’t go into production until later in the year before going on sale in the US market in August. It didn’t make it across the Atlantic until late Autumn.

Action Replay Mk 4.1 to 6.0 upgrade (C64)

Action Replay for the Commodore 64This is a very easy upgrade for your Action Replay 4.1 device. With version 6 of the software you get a few updates to the original software, and a few bugs are also fixed.

You will need :

  • 8 x 32k SRAM Chip (I used a UMC UM62256A I removed from a BBC Model B SRAM mod)
  • 28 pin DIL socket (You dont need this, but its a good idea)
  • 27C256 EPROM or equivalent EEPROM
  • Action Replay 6.0 ROM image (Available here.)
  • Soldering iron, solder etc
  • EPROM programmer

Action Replay - Front What you need to do.

  1. Program your EPROM/EEPROM with version 6 of the Action Replay software.
  2. Dismantle the Action Replay. Mine was held together with 1 screw.
  3. Take the PCB out of the case.
  4. Carefully remove the large PROM at the bottom of the PCB near the edge connector.
  5. Solder in the 28 pin DIL socket.
  6. On the underside of the PCB, under where you just installed the DIL socket, you will see 3 solder pads. Join the 2 pads that are closed to the 2 buttons at the top. Photo here.
  7. Insert the SRAM chip in the new socket.
  8. Insert the EPROM you just programmed into the ROM socket.

Once you have finished, your board should look like this.

SD2IECSD2IEC is a hardware mass storage device using an SD/MMC card and interfacing with the IEC bus. It is based on the ATmega644 microcontroller from the Atmel AVR microcontroller family. The most prominent use of SD2IEC

SD2IEC - Front

is emulation/replacement of a Commodore-1541 disk drive for a C64.

My board was made by a guy called ‘Charlie’. Its a brilliant little device!

Its very easy to use. You can copy either PRG files or D64 disk images. I’ve not found 1 D64 file that hasn’t worked. Ive tested it on my C64 and my C128 which has JiffyDOS installed. Its so much quicker on the C128 in JiffyDOS mode.

There is more info about the device at C64-Wiki.

 

 

My VIC-20 PC Project

One of my latest projects is to put a PC inside a VIC-20 case. I already have the very small system board built, with an OS installed and the VICE emulator.

I will be putting updates on this project on the following page. http://retrocomputers.wordpress.com/the-vic20-pc/

Make sure you check out this page in the next couple of days. I will be posting photos!

(Edit : Ive changed the system from Commodore 64 to the VIC-20 + corrected the link to the project page)
