Re: QL2VGA on American hardware

How did this work out for you? It works very well, with a good image quality. However, I am not sure my QL with JSU still have the video chip (ZX8301) that was installed originally in this north america QL, as I did many modification over the years. The one installed right now it a CLA2310. Another...

Re: Defective QL PSU

Probably more useful to monitor the voltage levels on the main 9v output whilst the QL is running. The requirements for the 15Vac supply are a lot less demanding - and even the higher voltages are within the specification of the small regulator IC's that reduce this to +/- 12V DC My guess is that t...

Defective QL PSU

Hi, I recently plugged my old original QL PSU to my QLs (I have a modern replacement for everyday use) and got unexpected results. This PSU has always worked great. But now when I plug it to QL #1 (goldcard) the QL doesn't boot and instead produced a very scary buzzing sound. When plugged to QL#2 (5...

Re: Breaking news: The QIMSI Interface

Peter,

Do you see any problem using your QIMSI Interface with a Aurora board (assuming the correct ROM interface converter) ?

Would you program it in C or assembler?
Assembler most likely. Would use it as computing accelerator for chess algorithm.

Re: Breaking news: The QIMSI Interface

I have 3 QLs and all of them are maxed out with either super gold card with mechanical hard drives, QL-SD on another and a V-Drive on the last one… but but I MUST have this new interface!!! 68040 like coprocessor that is difficult to use! What can be more appealing!

Re: ROM, 512k RAM, felt pads + VGA

Hi Chris,

Do you know if the VGA adaptor works with an american QL with its slightly different video timing ?
