Copy Corner was a great article written in INFO magazine. If first appears in issue #10 which dates May 1985. There was only a few installment of this series, but they are all very interesting. The article talks about copy protection and then usually reviews one or two copy programs. It starts by saying: Copy protection just keeps getting worse. Some of the latest titles include recordings out to track 40, that is five tracks beyond what the 1541 was designed for. Here is the two page article.
What is this? REU stands for RAM Expansion Unit, get it? REU!! SO what does this have to do with this copy site? Well I was looking for a way to copy a disk without making 3-5 swaps from Source to Destination disk, without using two drives. Well the simple answer was to add more memory (add an REU).
The three main ones for, Commodore was the:
1700 with 128 kB
1750 with 512 kB
1764 with 256 kB
These need a more powerful power supply to work. There is also something called the “Super 1750 Clone” which is the size of a normal cartridge, plugs into the cartridge slot and needs to extra power. This is one I own and use. It’s that RED cartridge below.
There’s one more to talk about called: GeoRAM this was by Berkeley Software and was to tie in with their GEOS operating system for the Commodore 64.
