Re: Interrupt vector and Minerva
Hi Wietze, I read from some manual that when using Minerva one should not change the stack pointer. In the Minerva romcode itself, I see there are assumptions made about the location of the stack pointer. Some minimal testing shows that this matters (in my code SP is set to $30100, and Minerva makes...

Re: Interrupt vector and Minerva
What does that do? Disables the interface interrupt (IPC activity). Value gets copied to ZX8302 interrupt mask register. QDOS never used it but Minerva introduced it to respond to IPC (Hermes). But it causes slow down on non-Gold systems (FLP activity, POKE!!53,128 restores performance). Don't know...

Re: Interrupt vector and Minerva
Hi there guys, I found that my most recent demo release is not Minerva-ROM compatible. Because I have no intention to willingly deny Minerva users to run my demos, Im interested in looking into what causes the incompatibility. Luckily for me, the issue can be reproduced using Qemulator! However, I ...

Re: Using the QIMSI-QL Link
I've created a new GitHub repository https://github.com/janbredenbeek/QIMSI-SER4 with the serial driver software I wrote so far. It's far from finished but should be usable for serial transfers between QL and Q68 or PC (for Q68, I recommend using SERNET v2.25 on both sides).

Re: Using the QIMSI-QL Link
Could someone post a photo of what the serial output connection from QIMSI would look like? What type of connector could be used on the QIMSI side? No photo here, but it's clearly identifyable in the QIMSI manual's photo. The serial interface is on the right-hand side of the QIMSI board as seen on ...

Re: Minerva4Q68
There is a tool on the Marcel Kilgus site that adds a few of the Q68-SMSQ/E commands to the QL-SD Minerva package. (CARD_RENF, CARD_CREATE, CARD_DIR$) https://www.kilgus.net/ql/ql-sd/ Thanks, I just discovered I had already downloaded this months ago. I have my doubts if this works for the Q68 (or ...

Re: Minerva4Q68
I've had a play with this. But I've found I can't do what I wanted. I wanted to start Minerva, then use WIN_DRIVE to mount whatever QXL.WIN file I wanted. But there's no WIN_DRIVE, or CART_DIR$ commands in Minerva4Q68. You have to use menu config to set the Minerva4Q68 WIN associations first. I sup...

https://github.com/SinclairQL/sQLux/commit/4a9e88e910ba4ae2a906a6815e0a3e666d0cb148 Was my fix for a very similar problem under emulation. During boot d1 is compared for an expected value, if its not found it reboots without RAMTOP set and finds all the memory, and not just what its supposed to. Bu...
