Brilliant picture from Amiga with RGB-SCART

January 25, 2012

I wanted to be able to hook up an Amiga 500 to TV with decent picture quality for an upcoming gaming session. Instead of using the lousy composhite signal or the dreadful RF antenna cable I wanted something much better because modern TVs don’t forgive low-quality video signal. In fact, flat panel TVs tend to make old systems look really bad. Low resolution and sharp, pixelled graphics (in contrary to e.g. real life video) transferred using blurry and noisy signal, and then displayed stretched and processed on a HD panel. You know it ain’t gonna be pretty! The best way to prevent the worst eyesores is to use high quality video signal at least.

So, off to make a RGB SCART cable for that Amiga. Read the rest of this entry »

Stuff from Retro-Donald

January 21, 2012

Just a quick heads-up, I recently ordered some stuff from Retro-Donald’s Sinchai-Shop. Finally the goods arrived, and above you can see the loot I got.

Top: Micromys V3. Below, from left to right: EasyFlash 3, MMC2IEC + programmed AVR, Nano SwinSID, Super PLA.

Sinchai.de is an online shop that is specializing in Commodore 8 bit accessories and DIY kits. Unfortunately the site is in German only, as is all communication and support. Additionally the information and instructions for the products may be very slight, and most of the product support seems to be at the German C64 forum Forum-64. The shop supports the community there and vice versa it appears.

At least the product assortment is very interesting, and they ship worldwide. And Google Translate is your friend if you are like me and don’t speak nor read German.

Apart from the language barrier and almost three weeks’ delivery time I’m very pleased with the experience. Might be that Donald is busy putting the now-released EasyFlash 3 boards together! The pieces I finally got are of good quality, and the packaging was well done. Postage rates were reasonable, and generally, so are the prices at the shop. My recommendations.

Reviving old C64-tower project

January 8, 2012

This is my C64 tower. It has been built nearly 12 years ago by me and a friend of mine. It has seen it’s best days long time ago, but now I’m about to make it better than it ever was.

Built into the old IBM case is a C64E motherboard (the new, short board) from a late C64 C and a much older 1541 disk drive. Basically the machine is an original hardware setup – including the original power supplies. The C64 motherboard is mounted horizontally at he bottom of the case. The C64 PSU is attached to the flank of the case – not very discreet I know. The drive mechanics of the bulky 1541 drive fit perfectly to one of the 5 1/4″ drive bays. The motherboard (or logic board) and transformer have been relocated around the mechanics.

An external power cord plugs into the rear of the machine. The mains voltage is routed to the original transformers trough a two-stage switch and fuses. The two stage switch makes it possible to power the C64 without starting up the disk drive and also to switch off the 1541 while C64 remains on.

The obvious issue of keyboard was also solved in a rather straightforward manner. The keyboard ribbon was simply cut, and then wired to the PC’s serial port connector at the back of the machine. An extension cable for the keyboard was done from old printer cable, which then plugs into the port. Not pretty but does its job!

The other necessary connectors were also routed to the back of the machine. A composite video, dual mono audio and RF antenna connections were routed to the added back plate of the machine using RCA plugs. The transparent back plate is in place of the missing PC PSU. Joystick ports are available at the bottom, as the motherboard barely fits inside the case.

The C64 and 1541 use the case’s power and HDD LEDs as their power LEDs. The power button of the case acts as a reset button for the C64. Read the rest of this entry »
