Agree with that - Q68 is targetted to be an SMSQ/E machine, no more, no less. There are a lot of other more "generally usable" SBCs out there that are much cheaper options.Tinyfpga wrote:I understood that one of the "positive features" of SMS was that it does not require an MMU. I imagine that implementing an MMU in low cost FPGA's is far from a trivial task. Would it not be better to buy a Raspberry pi to play with --nixs? They are also cheaper.
Well, what exactly do you miss? I2C is there and usable, same for serial and Ethernet, and if you have further needs to adapt external hardware, there's always the expansion bus. I agree some usable, simple examples would be useful, but building that would require someone with a personal interest in such things.Tinyfpga wrote: Something that would be interesting, is support, both in hardware and in software, for i2C, including i2c to rs485 for long distance communication.
Perhaps a Q68 bus to rs485 interface together with system support would be more useful, and probably easier, than an MMU.
The ability to control and measure external devices would, in my opinion, greatly enhance the Q68.
The Q68 can connect to the QL Network with a simple circuit, which with QLUB can connect Q68, QL and QPC2.TheManticore wrote:From the other side of the pond.. +1 on a deposit.
Additionally, I was curious about how networking is implemented on the Q68, Is it integrated with the PCB, and simply a matter of fitting the additional components while you are assembling them? (I ask as I believe I had asked for the Q68 board only, as I intended to install it in a custom enclosure).
The Q68 is a 68000 based CPU system implemented in FPGA, which does not have a MMU or FPU, nether does a standard QL even with a Super Gold Card.TheManticore wrote:Also, based on some previous posts, it sounds like you chose not to integrate an FPU on the Q68, is that correct?
I personally think Linux on the QL or Q68 would not be worth the effort, if all the Linux applications were ported to the QL/Q68 then why need Linux.TheManticore wrote:Should you choose to evolve the design into something more *nix friendly, please consider implementing both an FPU and an MMU (especially if integrating additional RAM).
