Bonecruncher (Commodore)

Does anyone have any details of the layout of the Commodore 64 and Amiga versions of Bonecruncher (i.e. where the maps and passwords are located)?

Re: A310 - late production or relabelled A4x0/1?

I had a 310, which I fitted a hard drive to, and ARM3 and 4MB RAM. I then cut a hole out of the label for the hard drive light (the hole for the LED was already in the facia). I then got hold of, somewhere, a A440/1 and swapped over the labels. The 440/1, IIRC, was not as highly specced as the 310 b...

Re: BBC Master Cartridges

One thing that annoys me about the Master Cartridges is that if you plug an EPROM into them, they then don't fit too well into the slots. They're fine with 'normal' ROMs. I also have a couple of Technomatic cartridges which accept RAM chips - both have 2x16K RAM, meaning I can get up to 8 banks of S...

Couldn't you use a PC PSU, as it doesn't require AC power (unlike the C64)?

Re: Repton - Around the World in 40 Screens - 80 Track Version

The 80T and 40T are identical, as far as I am aware. Certainly no extra levels. The disc itself, IIRC, is copy protected and is likely just going to be data saved directly to the disc (i.e. no filename). Without digging out my ATWIFS floppy, and rigging my Master up again, I can't be certain.

Re: Commodore 64 PSU replacement

The easiest way to replace a C64 or C128 PSU, is to build a 9V mains transformer and a modern +5V SMPSU together in a new case. Think that'll be the answer - what I'll probably do is get a PC PSU to get the +5V and +12V lines for the C64, and also my two drives alongside the 9v transformer. Power a...

Re: Commodore 64 PSU replacement

It's actually 5V DC + 9V AC. Apparently, the 9V AC is used to provide +5V and +12V DC inside the computer (so why the 5V DC from the PSU?), plus also feeds the Time Of Day clock (which is not used by anything). I'm not keen on modifying the computer, so it'll have to be a replacement PSU. I was ther...

Commodore 64 PSU replacement

Was moving my 'cave' around the other night and thought about the PSU for my C64, as I was moving it. It would be nice to be able to use a modern replacement for the supply, considering that the two 1571 (or are they 1541 mark II?) drives can run off a normal PC power supply.
