Re: VIC 20 - very low serial number - 0415 !

I remember City Bomber! Someone brought a VIC into school and we played that. At the time, the idea of a smaller PET with colour seemed pretty cool to me.

Re: VIC 20 - very low serial number - 0415 !

Nice machine! :D Regarding the serial number though, bear in mind that it says "Made in W Germany", and the serial number is prefixed "WG". So yours is the 425th made in Germany. Not all VICs were made in Germany (I would assume). I found this site which contains this list (edited a bit by me to mak...

I don't think so.

You've got me wondering now. I don't have my original tape any more but I do have the ...

Re: Return to E2P - the Electron Second Processor

Thanks Dave, not seen the article in its original format before. The daughterboard is not mentioned - so I think it must be contained within the user guide.

Re: Return to E2P - the Electron Second Processor

That makes 3!
The original design had a modification added to it, although I can't remember now if this is in the magazine or not. I think ìt must be. The mod was a small daughterboard with one chip on. If yours lacks this, it might be the cause of the problem.

Re: Return to E2P - the Electron Second Processor

A bit more experimentation has revealed that the issue is more complex than just an incompatibility with one particular item of hardware.

Long-time readers will probably despair to hear that I have resumed working on this extremely long-term project!

I've updated to the latest version, but it has not fixed the "crash on custom level" problem. This happens if you play the level "properly" or use the playtest facility within the editor.

Re: Meet my new Atom (warning: lots of images)

Images look OK to me. I'm not exactly an expert, but I would say yes, it is normal to have this many empty sockets if you have an expansion board of this kind. All the RAM is moved into the separate board, leaving all the old 2114 DRAM sockets free on the motherboard. My Atom looks like this. (Well ...

Re: What are people happy soldering ?

I'd have voted for "through hole", but actually I have soldered the SMT ICs onto the PiTube Direct level shifter with no problems. I don't know what kind of SMT those were though! So I voted for 1.27mm. Might have been less than that.

The two lines of text in between the top line (Acorn MOS) and the bottom line (BASIC) look unusual to me. Does the machine have any special roms fitted?
