The Sinclair QL Forum

Looks like an Issue 5 motherboard which originally had IC17 fitted but that's been snipped out after the ROMs have been upgraded to JM at some point. There's a Hermes manual and the co-processor is a Philips rather than the usual Intel chip so that could be a Hermes but I can't yet tell. A Philips-...

I've just posted a new paper called "The Sinclair QL in North America" on my website. It has details on the launch of the QL here in the US, the QL & T/S community, the QL shows, the vendors and even QL software written on this side of the pond. Nice to see a mention of QBOX :) . I re...

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...

Hi Jan, thanks for your comment, nice to see another Dutchie here :). Regarding the nop; yes, geez, is my face red. That is supposed to me ending in 5.... ;) Correct: vblRoutList dc.l 0 dc.l demoScriptHandler Where demoScriptHandler is part of the little kernel of my demosystem. That looks OK, thou...

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...

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 ...

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).

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 ...

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 ...
