Re: Bit of fun Part Two - CPU Swap

I can't recall if the Acorn Z80 Co-Pro actually came with a Z80 version of B Basic or not. It did, implemented as a CP/M application from memory. The only issue I'd have with that is the fact that upon startup it erm demands a data disc or such rather than drop straight into Basic, that's what I'd ...

Re: Bit of fun Part Two - CPU Swap

Why? The whole point of the Z80 copro is there was another OS to run, CP/M. There's no equivalent OS for the 6502, so what would be the purpose of a 6502 copro in this scenario? I like having a Z80 'core' and Basic on the front. But that may be because my erm 'computing life' started on such a plat...

Re: Bit of fun Part Two - CPU Swap

I guess the beeb would have a pile of speccy ports like the CPC, but as I wouldn't have bought one, it probably wouldn't have bothered me! The quality of these seems to vary quite a bit, tbh it seems some simply ported and make it work (I realise that's a fair bit of work anyway) but not take advan...

Bit of fun Part Two - CPU Swap

Following on from this topic , I felt given the erm 'nature' of the change it was well worthwhile posting a new fresh one about this. I've also as per the other topic posted it on the ZX forum too, although their change is the reverse. Anyway the question being, if the original design for the BBC Mi...

Re: BBC Master 2.5" hard drive

In regard to the pic in the first post by the O.P , at one time I had something vaguely similar although it was 'home made' It was an empty 5.25 single BBC drive with the IDE HDD interface and a small 1GB HDD inside too, as the drive case had a built in PSU too it was quite neat.

Re: Which games from other platforms did you wish was on the BBC?

Simply plug the ships leaks as they occur, steer it occasionally (more on later levels) and keep the engine topped up wit...

Re: Bit of fun - One change only

How about socketing the Elk's 6502 to allow for easy aftermarket accelerators? That's a good idea. It does seem to vary a bit (with quite a few manufacturers) when you look at different issues of boards to find things socketed or not. Sometimes they go back to a socket I'd noted. And some small cha...

Regarding the suggestion for the larger Elk case, this would of likely meant the PSU could of happily lived inside as well instead of being an external brick. While I'm here talking of Elk's, another 'one change' suggestion would of been the inclusion of perhaps a couple of ROM sockets. I did consid...

Spectrum 'bright black' is the same colour as black, so the Spectrum has 16 logical colours but only 15 physical colours.
