Mandelbrot fractal on QL

I was just playing with QL and SBasic, but the result, I think, looks nice.

QXL host computer

What are requirements for QXL card? I wanted to use small, quiet system, so as host computer I used Cyrix 233 MHz mini-PC with PCI and ISA slot (as QXL requires the ISA slot). VGA, PS/2 mouse and PS/2 keyborad connectors are present together with ethernet and USB. With MS-DOS 6.22, CuteMouse mouse d...

Re: Books about SuperBASIC

As said the Jan Jones book is superb, it's also worth checking sellymyretro, ebay and even amazon for QL books.
Now I'm selling one on german eBay. http://www.ebay.de/itm/Sinclair-QL-Buch ... 4177599a96

Re: Microdrive data line format

From this point of view, the ideal peripheral device was the ROMDisq (four expansion ROMs, e.g. Toolkit II, and flash-memory based storage). Pity, it was limited to 4 MB.
With larger space on flash, or with SD card, this will be unbeatable expansion.

Re: Using Microdrives Today

I think, that Spectrum Microdrive format and QL Microdrive format are too different, and the book will not help.

Re: Seen on eBay

I was interested in this, but all the removable chips are missing. Seven processors, seven ZX8301's, seven ZX8302's to complete this will eat much money. I wanted to use Q-LAN connections between boards to build a QL based parallel computer - like AppleCrate II ( http://home.comcast.net/~mjmahon/App...

Re: Microdrive data line format

Shouldn't this be the opposite?
Higher frequency for 1 bits (byte 255) and lower for 0 bits (byte 0)?

Re: Making my own Text adventure game

I think, that even in the ZX Spectrum community, there is no common knowledge, what "TZK file" means.

Edit: maybe TZX?

Re: Super Gold Card + Scart

I use their cables with SGC QL and with three different monitor types I had no problem.
Better thing than to force them to change the cables is to build analog / TTL switch for the monitor.
