The Sinclair QL Forum

Maybe I could use QIMSI gold instead on this QL and swap the SD to one containing a dummy $C000 ROM

That is one possibility. You could rename a toolkit of your choice to QL_ROM.SYS and copy it to the card, or a file containing just $FF.
If a legacy QIMSI is updated to the latest FPGA logic, it ...

Not possible due to QLiberator abusing the upper three address lines. 512 MB is maximum.

Why "missed"? You can still vote.

I'm fine with the existing Q-emulator, would prefer the arcade game.

Maybe connecting a Raspberry Pi or Pico to the Q68 expansion bus could achieve this, just then got write the SMSQ/E device driver and the Pi code to send data from the GPIO pins attached to the Q68 expansion port to the Pi USB connector.

A directly connected FDC controller as Dave suggested ...

Floppies are fun.

I have the opposite experience. Sometimes I still have to use floppy on the Q60, and I hate it everytime. It's the most unreliable medium, practically all my old QL floppies have damaged files. Even the tape of my microdrive cartridges has aged better. Also floppies tend to be ...

At the moment I use only QLib programs which already have a built-in in runtime The solution is actually quite simple: simply load "QLib_run" in the boot program, then everything will work....

:D :D :D

Not reliably, because there were different versions of "QLib_run". If the library is ...

Especially in this case, where a million more computer guys use it for Linux packages (former "RedHat Package Manager"). Even myself. ;) In QL terms? Never.

Sure. I've used Q40/Q60 and UQLX a lot, but never any Qliberation programs. Didn't come across that "Resident Program Manager" in over ...

A QL with >= 68000 maybe?

Hi Dave,

not sure about V2. At https://omega.webnode.page/products/product-1/ there are GAL sources in "qubide_gals.rar" which might be worth looking at. If I was you, I'd rewrite the logic from scratch though, using a PLD.

Good luck, Peter

By the way, the "68K bandwidth theoretical best-case" table looks wrong to me. E.g. the 68060 bursts 16 Bytes in 5 clock cycles maximum.
