Re: DP's Sprite Generator bug/issue/emulation

I think this is down to a bug in q-emulator - suggest you send all files to Daniele Terdina to look at on his test system. I know that Lands of Havoc has a similar issue - move slightly to the right or left and the character disappears. Daniele thought that this was linked to my removal of the copy ...

Errors in QL Service Manual

A customer has been investigating the differences between his issue 5 and issue 6 motherboards in his QLs and believes that there are errors in the Service Manual relating to the issue 6 motherboard. It may also indicate what the HAL chip is for on the issue 6 boards! 1. The circuit diagram shows th...

Re: Strange problem with Display Toolkit and Q-emuLator

I have just tried your program using the MGE_ROM, Q-emulator and the DISPLAY_cde from the Sinclair QL Homepage - http://www.dilwyn.me.uk/tk/display2.zip

Maybe the version of display_code you have has a bug (or is a different toolkit)?

Re: How to know the device of the last file loaded?

Unfortunately, no, there is nothing stored on the QL to signify where the last file opened was stored - this is partly due to the way in which the operating system's OPEN calls work, because the one call has to cope with any type of object which can be OPENed (or CLOSED). The best way is to do what ...

Re: Strange problem with Display Toolkit and Q-emuLator

The problems with the JM ROM are no doubt due to the fact that you cannot generally use a toolkit in the same program which initiates the toolkit on the JM ROM (this was fixed in JS ROM). Hence you may need to have a double boot program - ie. a short program to use RESPR, LBYTES and CALL to link in ...

Re: Problem at start-up

I don't think there are any user groups in Finland - and I only have 4 QL users on my customer list from Finland. I do think that it will be a steep curve to remove that memory upgrade, as all of the chips have been piggy backed - it is a lot of de-soldering. It might just be easier to get another Q...

Re: How to know the device of the last file loaded?

There is no function for this, as the QL does not store any information about the last drive accessed.

However, if you use the PROG_USE and DATA_USE commands in Toolkit II to set up the default program and data devices, you can access them with PRINT PROGD$ and PRINT DATAD$

Re: Modifying modern floppy drive for QL

Of course, the second floppy disk drive just needs to be placed on the cable before the twist on pins 10+12 (as PC floppy disk drives are set up as DS1 (FLP2_) by default).

Re: Problem at start-up

My first step would be to remove the internal memory upgrade - these were slower than the external memory upgrades in any case, and it is probably one of these memory chips which has failed.
