Any chance to place it at $1C060 ? Then it would be the exact same.
Also my newer machines have a hardware identification register at $1C000, where 0=Q68, 1=Qzero, 2=QIMSI.
If you like, you could set numbers from 8 onwards.
Interesting - so what's happening with 3-7 future products?
I just thought room for five more machines is sufficient for my lifetime. At the moment I only think about 3+4 though.
If Leon starts at 8, that would allow a single bit to distinguish the designer.

Does it work with a faulty ZX8301?
Thanks

This one NEEDS the zx8301, it doesn't care if CPU, ROM, RAM are on board or not.
If you want to also replace zx8301 then you need the "FPGA replacement of ULA" board, it has the same features.
I think it was very smart from Lion to separate the to topics. Making on one hand a replacement for the ZX8301 and on the other hand a expansion card with all this great features.
The replacement of the ZX8301 is already available. You can build one from the infos on his project page or you try to contact Tetroid. BTW did someone get a replacement from him?
There is certainly a demand on expansion cards in the community, the request for prices and delivery times of the QLion card here in the Forum shows it clearly. All those people suppose to have a working QL and no need to open it and remove the working ZX8301. So the plug in card is the way to go.
I don't own the QLion card myself, but have to say it is a fine peace of vintage hardware.
Great for those who appreciate a classic Motorola CPU. Curious if there will be a 68020/030 variant someday.
Just in case it is not obvious: Minerva supports the 68020. And the 68020 has dynamic bus sizing, i.e. one can easily keep the 8 bit bus toward the QL, while using 16/32 bit toward SRAM and FPGA. With the video controller outside the QL mainboard and SRAM instead of DRAM - as the QLion has - it would outperform the Miracle SuperGoldCard.
Hi, if you are doing something new, what you pls mean about this intentionally cpu-decoupled 3V3 PCMCIA-inspired (only peripherals though), later also MIPI DBI-B + SPI DBI-C (8pin conn) inspired "bus". I plan to use it with cheap 2mm pitch 2x15pin connectors having max 7 slots on backplane for hw tinkering against old cpu's various kinds, over CPLD/FPGA. It probably can be driven even over single serialized/rs485 SPI link entirely. At least I hope )) ...7xbus https://chatgpt.com/share/67275032-7fd4 ... 3e96f89e82
future products?
