Under q-emulator I’m doing this:t0nyt wrote: Mon Apr 29, 2024 7:03 pmIt seems to run under Minerva in q-emulator, but I’m not able to test on my QL until I make a final decision on whether to switch ROMsdex wrote: Mon Apr 29, 2024 6:50 pm In my opinion, the only essential software, which does not run with Minerva, is the game Vroom.
May be I could do something with this? Though it would tie up the expansion slotdilwyn wrote: Mon Apr 29, 2024 8:52 pm Yes, one of my QLs has a very old QLEA ROM switcher board where I can switch between a Sinclair and a Minerva internally. It even has different colour LED for both. The Minerva could do with updating at some point, it's not one of the more recent ones.
The other QL has one of Marcel's QL-SD-ROM devices with multiple ROM images on board, but no internal ROM IIRC (shows how long since I last looked inside it!). Sadly, no longer available.
There's also the option of having one of Tetroid's ROM switchers if still available.
And of course EPROMs on plug-in cartridges (a 64K EPROM could hold a Sinclair or Minerva EPROM plus a 16K Toolkit 2), although that ties up the EPROM slot.
I believe it's an in-store Demo board so I guess Sinclair designed. Each screen is a mock-up with info (rather than the actual programs)dilwyn wrote: Mon Apr 29, 2024 9:28 pm Never seen one of those before - what type is it (or is it homebrew) ?
As you say, ties up the expansion slot.
And depending on where in the memory map that puts the ROMs, might not allow expansions like Trump Card which use space allocated for ROMs to make up the difference between 640K total RAM and the 896K total of Trump Card.
Never tried adding a Minerva via the main expansion port, don't know if all signals needed are present there.
All these things have their merits and drawbacks.
Well I’ve bitten the bullet and installed Minerva (without breaking my JS ROM board this time!)t0nyt wrote: Mon Apr 29, 2024 7:03 pmIt seems to run under Minerva in q-emulator, but I’m not able to test on my QL until I make a final decision on whether to switch ROMsdex wrote: Mon Apr 29, 2024 6:50 pm In my opinion, the only essential software, which does not run with Minerva, is the game Vroom.
Just loaded 1.98 a1 into Q-emuLator and Vroom doesn't work nowt0nyt wrote: Fri May 03, 2024 6:53 pm It's odd that it runs in Q-emuLator but not on real QL?
The only difference I can see is Q-emuLator is on 1.98 and my QL is 1.98 a1
