Re: QIMSI

Referring to the QL Technical Manual by Tony Tebby, in Section 2.4, page 15: 2.4 Start-up The first thing that Qdos does when the system is reset is to execute a RAM test. This test determines the amount of contiguous RAM present, and if there is a...

Re: 3.5" Floppy Disk Issues

Hi,

I thought the Trump Card could handle Double Density Disk Drives (720K or 1440 Sectors)

Re: What is really in the header of binary files?

HI, This QL Emulator file header attachment is a real mess, I do not store QL executable files in a non-QL environment and extract all compressed files into a QWA or QUB container file.
