The Sinclair QL Forum

Yes, It happend on real QL also, not only in the logo in other parts also, between text and background, like In the like of the red dashes of "-- press any key to start --"

Which is a curious and sad thing, because cp/m was liberate as OpenSource years ago...

This versión work with disk directly? or do the same that success, that create a file with the cpm filesystem and difícult the share between CP/m and QDos or other os?

For me It do not work on a BBQ (minerva)+ Trump card, It show some text and at the end: FTEST is not loaded. FOP_IN is not loaded. FOP_OVER is not loaded. ALCHP is not loaded. But if I boot from a disk where I have pe, It load correctly and is very good. There is some typo in the spanish intro: Line...

I had problems with 2 components in the past: The transistor, chinesse ones are slow or something and got no boot message of the card. Also 74ls04 chinesse for the oscilator cause me problems, in this case you got boot message but not recognice the board (the board shall show boot message even witho...

I don't know if there is interest, but if you post somewhere pictures of the PCB, both sides, I will do my best on reverse engineering it, to preserve the schematic and share it for future repairs or whatever.

I test this cartridge some time ago. Basically it contains a basic program for the quality test of the QL, some basic test like keyboard, serial, microdrive and graphics. I think it's only useful to detect bad soldering on connectors during manufacturing, it depends on a fully working QL to use it. ...

A Genius Bus Mouse is basically a atari,amiga or BBC mouse (wiring can not be the same).

You can use it on QL with a QIMI or Mersey mouse interfaces, also as a replacement for the MICE cartridge mouse, and probably but not sure with a Sandy SuperQboard.

For my, the keypoint of this is that he was able to sintetize the wd1772, this means that is posible to do new (cheap) interface disk for the QL.

Nowdays the WD1772 is more than 50$ and you alwais risk about counterfield chips.

In my opinión, two interesting things for future games in the QL will be AGD and CAAD, this compiler/framework/engines has been used to provide high quality games for several platforms and if we got a versión for QL will got instantanely a lot of games a warranty of future ones.

Have I2C pins and support for read and write will be a good thing. As a first step, I think is not necesary to have the RTC or support for it in ROM, if you add the minimum instructions to manage I2C from basic, later is possible to add a program on boot file that read the RTC and update the QL cloc...
