Re: Random hardware ideas!

The Vinculum chips are far easier to implement than a "standard" USB host controller. They actually might be a solution for the QL. But I go with Peter in saying "Solution? - To what problem?". Keyboard/Mouse is not really a problem, storage neither, and printing should be solved...

Re: SERNET question

Sernet used to be part of the SMSQ/E distribution of the Q40 and Q60 computers and was also offered separately, I think through Jochen Merz.
I have no idea about its current legal status.

Re: Fun things to do with an MC68EC020....

You might also want to consider PCB routing issues: You'll be having up to 6 buses on your board (Address of different width, data of different width and control with some QL-specific signals, each both locally and towards the QL), depending on how far you want to be able to decouple your board's ad...

Re: Random hardware ideas!

Anyone interested in the driver side? I have programmed two (full) USB drivers in my life - The first and the last one (incidentally, the same one). USB as such is not so hard - you just hand small blocks of memory to and from the hardware. The problem is: You need to put USB devices on top of you ...

Re: MAKE_DIR command needed for uQLx

Text87 should actually work in uQLX when you set it up in original resolution and with a non-Minerva ROM (JS or MG). This makes uQLX emulate the video memory just like on the QL and in the same layout - In this case, I don't see a reason why Text87 shouldn't work.

Re: Q68 case

Dave,

honestly: I doubt that anything the average sausage laying machine ;) could produce would look more professional than this really sharp case

Re: (Nearly) solved: FuNction which tests if a variable is set

Surely a nice and entertaining exercise trying to move SB windows about - But, the WMOV command that is part of the now free EasyPtr package (see Marcel's site) does that using a machine code extension nicely and interactively, if you want.

Re: Using ZX Microdrives on the QL

My discovery was that you can use only one extension microdrive unit on a QL if they are used backwards as forced by the connector. When fed from the left, they know their position in the chain to do drive select, when fed from the right side this doesn't seem to work right. That was assumed as a g...

Re: Using ZX Microdrives on the QL

Then I must have been lucky with mine - My (single) Spectrum Microdrive that came with the IF1 that I no longer have worked perfectly on the QL. I was under the impression everyone's does. Apparently not.

Re: MAKE_DIR command needed for uQLx

Depending on the file system, it might simply be not implemented in uQLX. Last time I looked, there was no MAKE_DIR support in the emulator for QXL.WIN file systems, only for the native file system - Don't know, though, whether anyone bothered to implement it in the meantime. Even if you had a MAKE_...
