The Sinclair QL Forum

Dear Leon

May I please be added to your list of friends?

Hi again Rich! What Issue board is it? I ask as, if an Iss5, the 8302 sits on the 'private' VRAM/8301 bus and would be impacted more by any anomalies with the 8301 ULA or memory/bus transceiver/address multiplexors (you know THAT story!) Given that there have been issues with the 8302/DRAM in the pa...

Hi again Rich! I'd also be tempted to reseat the existing 8302 - especially if the legs look in any way tarnished after so long in storage. Given no MDV activity what-so-ever, either the 8302 is not managing the COMMS Clk and COMMS Data/out lines properly, or else one or more of the pair (PNP and NP...

Hi there! Given that the IPC (which handles the beeper, Serial input and the keyboard) is connected to the rest of the system/CPU via the 8302 ULA, and that ULA also directly handles the Microdrives, it seems likely that the 8302 is at least partially faulty. That said, if the keyboard itself is res...

Thanks for the feedback, gentlemen! That is encouraging! I'll fire up a new thread in due course on the topic of the 'X-Net' (for Cross-platform Network) idea. @pr0f - I think I follow your comment - alongside the cross-platform idea, I've been thinking about how the Sinclair Network could form the ...

Just to add that the RetCon event went very well this year. First time for the QL to be on show and I got lots of interested people asking questions, including a lovely Ukrainian couple who were intrigued by the QL and shared their story of growing up with the Spectrum clones coming out of Russia at...

Good afternoon everyone! Just taking the opportunity to publicise this year's retro computer event RetCon 2024 in Greenford, West London this coming Saturday, 15th June 10am-5pm. Whilst not traditionally QL focussed (I plan to change that!), I myself will be demonstrating effective networking betwee...

Good morning Steff!

Welcome to the party - if only to find a good home for your well-cared for QL

If the QL is still available, I too have a friend who is looking to get his feet wet with a QL and hasn't had much luck on eBay recently, so I've sent him the link to this post.

Wishing you well.

Agreed

Hi again fuasn! ... hm, that sounds very thrilling, but i have problems understanding why the extension should be in the address spaces mentioned shouldn't the end of the add-on peripherals address space be $E0000-1 ? especially that in this case it would be $F8000 . isn't that already the add-on ro...
