The Sinclair QL Forum

Hi Bytesguy! Well, that was something of an adventure, wasn't it! Some of those switching regulator replacements can certainly be noisy and, given the closer proximity to the MDV in slot#2 versus slot#1, coupled with (typically) the MDV in slot#1 having a simple shield around the ULA, the end result...

Hi TCat! Some time ago I designed a number of methods to add EPROM (NVRAM, actually) in to the upper 128KB area, allowing for up to 640KB (additional = 768KB total) RAM. I have placed most of those utilities in that space, including many other DIY TK routines as well - all merged with T & EM (th...

Hi Steve I have been reading your thread on loading QL screen-files in to QPC2 - very interesting. However I'm left curious, as I have been doing this using the normal LBYTES approach without difficulty - as long as QPC2 is set to 512x256 and the relevant MODE to match the screen-file. Rather than u...

Hi Bytesguy! In addition to my PM of earlier today, I'd recommend you testing one of the suspect MDV units in the position of MDV#1 of the second QL. It is highly unlikely to cause damage to the QL, and would quickly confirm whether or not the first QL mainboard was contributing to the MDV format fa...

Thanks Badaman - what an interesting use of the otherwise oft-neglected RECOL procedure!

Hi Dave

I can confirm that I continue to receive the periodic Quanta magazine, so my understanding is 'yes, Quanta is still very much alive...'

Sounds like a sensible plan, Vyper68!

Hi agan!

Being reminded of Vitaly's 'multi-ROM' availability, I'd recommend like Chr$ to go that route as the path of least resistance

However, should you want to 'tinker', just let us know - several options, depending upon your taste...

Hi Vyper68 :-) You have a few options and the final approach would be determined by a few factors, namely: a) Whether or not your Issue5 board has IC17 still fitted (later builds - I forget which build-standard - settled on ROMs and dispensed with IC17 - originally a quad 2 i/p NAND) b) How much you...

Hi Bytesguy!

OK, so I'm stumped, but still thinking...

That your vDrive formats indicates that the digital signalling from the 8302 is all-good.

Back to you once I've pondered some more...
