Hi you MSX lovers! This might interest all you speed-freaks (and I mean hardware-wise, for those who still use a standard 3,6 MHz. MSX): In the past I have developed my own turbo-circuit, I call it MSX Super Turbo, and this has been entirely through the process of refining, testing, updating, redesigning, having it built into a bunch of MSX machines, and let these work for a couple of months (or years), to find out any problems with it. In other words: we're talking about a 'solid' piece of circuitry here. What is it: it is a solution to the general problem of switching the clockspeed of a Z80 CPU between 2 'random' frequencies, that don't have any relation to each other (unlike for instance the well known 7 MHz. design). Because of timing requirements of the Z80 CPU, this is not all that easy, but I found a good way to do it. Several people have been asking me if I still build these things into MSX machines, and I'm rather reluctant to do it, having not TOO much interest anymore in MSX, were further development is concerned. Therefore I've been wanting to put my stuff on the web, so that anyone interested can build it for him/herself, or find someone else to do it for them (and don't need to bother me about it anymore). Only: they would ofcourse need stuff like the schematics, a practical building description, and some info to go with it. That's coming up now! In contrast to other things I (have) put on the web, I will use a new approach here: I will put everything on this on the web, as soon as I have it, in other words: if a picture doesn't look right yet, I will put it up there anyway, and if I have a better one next day, there will be a better one up there the next day. That's where you come in: ofcourse you will find a mess on this page, and I want you to tell me what should be done! The end result will be that I have my design available on the web, you have an excellent piece of MSX hardware 'for grabs', and you will know that the form it's available in, is tailored to YOUR desires! So, I have 'allocated' the following address for it (in the page itself is a link to it, so that you can use a previously saved version to jump to the web-address where it came from): http://huizen.dds.nl/~alwinh/msx/supturbo If you want to, please add this to MSX hardware-related pages, so that other people 'just browsing' will come along, and be able to comment on it.
