Re: Minerva Mk2 Remake

Ah yes, that's the thread I was remembering - thank you! I see now that the zip archive I uploaded only included the original plus a more readable version of Tony's original EQN file. I've since found my updated version 'v1.10' - attached here. This version uses Pin 6 (which I chose to rename to 'Up...

Re: Minerva Mk2 Remake

Hi Derrick et al There is a simple GAL update that allows you to selectively enable/disable the upper 16KB of the onboard 64k EPROM (disabled in the original design). With the addition of a micro SPDT (or should that be a DPST???) connected to the board with a flying lead (3-way), you can then have ...

Re: FPGA replacment for the ZX8301 ULA and more

@Leon

As I have a range of QLs of all three motherboard versions as well as both GC and SGC, perhaps I can also do some testing if I could purchase your ULA replacements?

I'll PM you :-)

Ok. Once I've completed work on the next ND-Q68 driver release (imminent) and touched-up the latest ND-MQ Net driver for the QLUB, I'll turn my attention back to the MQ/QLUB technical note.

Re: QL replica

Hi everyone! It is interesting to hear others' views and experiences re-purposing the original QL case to house a more modern heart (and lungs...) Just to add my own experience fitting one of my Q68s in to a QL casing (and a bit more besides...), I attach some photos. If anyone is interested in the ...

Re: Bug in string handling in SMSQ/E

Hi everyone! I concur with Per - the case of "n TO n-1" (or, similarly "n+1 TO n") results in a valid, empty string and is "philosophically" not an error. Its actually quite useful (for lazy programmers like me), as you can catch the result and know that you have now sc...
