Re: Testing for installed TURBO

That method should work with any toolkit function that
  • does not require any parameters
  • can be relied upon to return anything different from 0 or an empty string in the default case

Toolkit II DATAD$ could be an example to test for Toolkit 2.

Re: Sinclair QL - blank screen.... HeLp!

In case the QL microdrive doesn't show activity when you press F1, the fault is most probably not with the video circuitry. The QL should just ignore a dead 1377 and go on with its startup, so no microdrive at F1 is a bad sign. +12V and -12V are generated by IC37 (7812) and IC36 (7912) - I assume yo...

Re: Sinclair QL - blank screen.... HeLp!

Hi, First: If you press F1 on your blank screen, does mdv1_ start to whirr? If yes, it truly is a video problem, if not, we need to look somewhere else. Nearly all video failures normally indicate a faulty 8301, this is a socketed chip, so I would assume you already checked that. When you're saying ...

Re: Best QL UK ROM

There never was an official MGUK ROM.

Apparently, a few people patched English error messages and other strings into MGG or MGIT and created an MG ROM with English messages and keyboard layout. One of them is available on Dillwyn's page.

Re: SMSQ/E V.3.31 compiled for GOLD CARDS

Simone,

SMSQ/E should support the Miracle hard disk - there's extra code in there and some comments in the release notes.

You could try re-enabling the Winnie ROM after SMSQ/E has loaded with

Code: Select all

CALL $C000 + PEEK_W($C006)

Re: QL Snapshots

Hi, I hope a software routine could could achieve this, but most of the QL games I have tried to disassemble in the hope that they could modified to run on a modern QL system, run in Supervisor Mode and probably have the Interrupts disabled. So the multi-tasking is stopped, how would the monitor ro...

Re: Issue 8 and WiFi

That's all the same issues the Multiface had to "face" - You couldn't restore 16k dumps on a 48k machine and vice versa, and you couldn't restore Opus Discovery dumps on, for example, a Betadisk system. Later Multifaces even artificially restricted re-loading of dumps to computers that had...

Re: Issue 8 and WiFi

Martin, I guess special hardware wouldn't help. The QL already has most of the hardware that was added to the Spectrum by the likes of Multifaces - A button to trigger an NMI and some memory that holds the service routines - Only that in the Multifaces it was an EPROM. What you need is a piece of so...
