It's nice to finally be able to contribute something to the Commodore community after only downloading stuff for a few years. I'm sorry about the size of the scans, but I didn't want to compromise on the quality. If I had chosen a lower resolution, the text would have become almost unreadable. >According to the PCB scan, the cartridge has six 2114 chips, which makes >me suspect that it has a built-in 3-kilobyte RAM expansion. When I plug it in to my VIC, it says "3071 Bytes free" just like it should do according to the manual. Wouldn't it show more free memory if there was a 3k expansion in there? Or do you think part of the program is copied from the ROMs into RAM? >Alternatively, you could try remap the 16k expansion from BLK1+BLK2 to >BLK3+BLK5, but you'd still need to plug in both the 16k expansion and >the 3k expansion simultaneously, or the program won't work. I've thought about that, but I don't think it's worth the trouble. I think I'll go for Ruud's or Adam Bergström's internal 32K expansion instead (or wait for your cartridge to become available). To MagerValp: I have already read your article, but I don't like the idea of putting a soldering iron directly onto the VIC's chips. I do live in Gothenburg (Mölndal to be precise). I'll ask Tema Elektronik what they have. /Niklas Message was sent through the cbm-hackers mailing list
