Re: FPGA replacment for the ZX8301 ULA and more
Awesome, Leon! Now, just when can we get our hands on one (or more)? :-) (No pressure intended...) BTW - should a firmware come about in the future, what sort of ICP programmer can one use to reprogram your ULA replacements in the field? I have a Lattice USB programmer that does the FPGA on the Q68 ...

Re: what is the difference between a ql microdrive and the spectrum version ?
Hi again techy! Ok, so you want to attach a ZX MDV unit within the nice QL style external drive casing (I think that was originally designed for the vDrive.) Makes sense. The other point that becomes relevant is that the orientation of the MDV expansion bus is reversed between the QL and Interface-1...

Re: what is the difference between a ql microdrive and the spectrum version ?
Hi techy! There is in fact very little (substantive) difference indeed. Here are the main points that I can think of: A. The drive electronics of the ZX unit are all incorporated in to the enclosure, with the equivalent of the power circuitry that drives the motor and Erase line on a fixed, but stil...

Re: SMSQmulator v3 and the QLUB Adapter...
Hi Daniele! Interesting idea... It would certainly be helpful to potential QLUB users to have more ready access to the driver, rather than searching for it here and having to pull it off the Forum or else Dilwyn's site, but I think it does belong on the 'QL' side rather than part of the Emulator - i...

Re: Serial QPC to QL
Hi Just start with Martin's suggestion below - copy directly with COPY 'ser1hz' to 'con_' on the QL to avoid latency waiting for tokenisation - and get a clearer idea of precisely how many characters arrive successfully before things 'hang' (and the I might suspect your USB to Serial adapter on the ...

Re: Software updates
Hi Per! Did you notice whether or not the Q68 bootloader detected a 'normal' or 'extended' PS/2 mouse at start-up? (It flashes-by a bit quick...) I find that my extended PS/2 mouse isn't always detected as such intermittently. Probably a timing issue, but not something I usually bother about (I hate...
