The Sinclair QL Forum

Ciao Fabrizio! I don't have an answer to why your Q68 should restart like that, though I have some ideas. However, if you are more interested in getting a working solution to time sync your QLs to the Q68, you might want to take an older, less exotic but perfectly effective approach that was origina...

Marvellous!

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 ...

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...

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...

Hi Peter!

I guess you meant '...rise and fall times are too low/fast...'

Hi Jbizzel! My boot file looks like this - not with xxxx yyyyy zzzzz, but the file sizes. 100 base1=RESPR(xxxxx) : LBYTES FLP1_PTR_GEN,base1 : CALL base1 110 base2=RESPR(yyyyy) : LBYTES FLP1_WMAN,base2 : CALL base2 120 base3=RESPR(zzzzz) : LBYTES FLP1_HOT_REXT,base3 : CALL base3 110 LRESPR FLP1_PTR_...

Great work, Leon!

Hi again Jbizzel!

Which is about line 88 in the original code I was trying to copy

And how many characters would you say those 88 lines represent?

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...
