Have a Helping of 8-bit Holiday Cheer!
0Here is a great post I found the other day on BYTECellar about various old demos about the Christmas Holidays.
I’ve been a computer guy for a long time now, but I’ve been enjoying Christmas even longer.
I got my first computer, a TI-99/4A, on Christmas morning, 1982. I was 10 years old, and from that Christmas on, it was games and hardware I wanted Santa to leave me under the tree. On through my teenage years, part of my ritual for getting into the Christmas spirit and enjoying the holidays was downloading and watching Christmas demos on whatever system I had at the time (and every platform out there had a few of them).
Enjoying these demos is a personal tradition that I had, sadly, long left behind until last Christmas when I was inspired to seek out one of the demos I remember best, Audio Light’s 1985 musical slideshow for the Atari ST. With the help of an emulator, I captured it to share online with readers.
Here, a year later, I recently brought it up and watched it run through it’s pixellated images and 3-voice musical holiday greeting. As I watched, it occurred to me that it might be nice to gather a few of the other demos I remember from those good ole’ days and present them here, in order to perhaps share some of the holiday cheer that they used to inspire within me.
The following list of demos ranges across a number of platforms of olde. I’ll start with the Atari ST demo I presented last year. Happy holidays, and I hope you enjoy the shows!

Action Replay Mk 4.1 to 6.0 upgrade (C64)
0
This 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
What you need to do.
- Program your EPROM/EEPROM with version 6 of the Action Replay software.
- Dismantle the Action Replay. Mine was held together with 1 screw.
- Take the PCB out of the case.
- Carefully remove the large PROM at the bottom of the PCB near the edge connector.
- Solder in the 28 pin DIL socket.
- 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.
- Insert the SRAM chip in the new socket.
- Insert the EPROM you just programmed into the ROM socket.
Once you have finished, your board should look like this.
SD2IEC – Commodore to SD Card adapter
1
SD2IEC 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

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.
Retro Desk for April Fools Day
6One of our DBAs at work decided to go on sabbatical. Part of the company policy is that if you do go on a sabbatical, you have to leave your company laptop behind.
Nick returns to the office on April 1st, so we thought we would play a little joke on him. We are going to say that we had to give his laptop to someone else. In its place, he now has a Commodore 64 sitting on his desk. Check out the photo below!
We didnt have a Commodore 1084 monitor to hand so we had to use a 17″ TFT screen. Obvously, the C64 does not have a VGA or DVI output! Luckily I had a VGA box going spare. This allows you to connect a composite video device to a VGA monitor.
