= On original designer's webpage. I've been happy with how it was for a long time (just mirrored copies), because people knew where to find it, and contents was still accurate.
Unfortunately HansO pulled most of his pages recently (thx. Hans, for hosting a copy so long!), leaving -sometimes partial- copies in random places like this. Somewhat silly situation IMO with me still around & having my own site. So - memory cycles, M1 cycles, wait cycles, duty cycles, clock cycles & more @ Bitcycle.org:

If you're hosting one of those old mirror copies, I recommend you replace that copy with a link to above page. Easier for you, easier for me & I intend to keep that online for a loooonng time. Changes:
- Added generic procedure on how to build into MSX machines (with pointers to related info), with tips on how to do it in small steps. So that if something goes wrong, you only have a few changes since last working point, and should be able to find cause of problem faster. I always try to minimize steps myself, not because things go wrong so often, but because it's so easy to make mistakes, and I don't like backtracking through a heap of changes... ._,
- Info on possible improvements - if you're planning use of this circuit, you might want to check that section.
- Re-formatted the webpage, with many small edits here & there.
In case you were considering a turbo upgrade: I think Repair-Bas may still have some 7 MHz. kits ATM, suitable Z80 chips are still for sale at large online sellers like Digikey or Farnell, your local electronics shop may still have a Z80B on offer, and 74HCxx logic can still be bought 'everywhere'.
Btw. if you're hosting a copy somewhere that includes my e-mail address in plaintext, I would very much appreciate if you could remove that (at least the e-mail address, that is). Not that you can't find my e-mail elsewhere, that the one on my homepage has heavy spam-armouring, or that I'm getting much spam, but... I wouldn't want to get more. B-) Thx...!!
