Re: Newbie: Where to start to learn QL assembly language?

(although I think GST's Macro language still has a bit more funky features). YEAH! I love it, especially the syntactical sugar macro GOTO (It's really not needed! Really just syntactical sugar) p.s.: Thanks for info about GWAS(S/L) Well, GOTO is a bit more than syntactical sugar. I've used it a few...

Re: ICL OPD

My mentioning of sequencial access only on the Spectrum: The Spectrum doesn't have a concept of a user-modifiable file pointer - You cannot append to a file once it's closed, you can't write to a file you have opened for reading (that is, no "rw" mode) and you cannot access specific recor...

Re: ICL OPD

Even the Spectrum supports random access (in a sense that it can scatter-load parts of a file - the physical access to the media is always sequential since it's a tape loop!) when using LOAD etc. The QL is more sophisticated in that most of the physical access is done under interrupts so normal pro...

Re: ICL OPD

I do not quit right remember but someone told me, that MDV handling on the Spectrum/IF 1 was hardware and on the QL it is software or vice versa. That's not true. Microdrives on Spectrum/IF1 and QL basically work identically. It is true that the QL implements more software, because it supports non-...

Re: Newbie: Where to start to learn QL assembly language?

GWASL: http://www.dilwyn.me.uk/asm/gwaslp08.zip The "light" version of the GWASS assembler that runs on 68000 (GWASS needs a 68020 processor) I dunno GWASL, what syntax does it use? The one from the AS68 assembler or the traditional as (e.g.) the GST Macro Assembler? It uses Motorola nota...

Re: Flightdeck program

To quote the technical guide: For monitor operation, a 50Hz 624-line non-interlaced system is used; this is the same system as is used on the English QL. The full 512x256 pixel display is available, and the default windows and character size are the same as for the monitor mode on an English QL . Fo...

Re: 512k + Backplane

Would be interesting to see whether the board supports a GC/SGC on the backplane - these sometimes have unexpected data directions.

Would also be interesting to see if the backplane needs to be connected directly to the driver board or whether a piece of ribbon cable could be used in-between.

Re: Q68 Ethernet

Yes, there doesn't seem to be one, at least not for relatively recent Windows or MacOS X versions. And it's highly unlikely that someone will provide one - SLIP has been obsolete for years, replaced by the (largely MS-driven development of) PPP. Hi, I do not use Windows or MacOS X, does mean it is ...

Re: Q68 Ethernet

A big problem with SLIP is lack of Windows support. At least I never found a solution. SLIP would more or less restrict the other end to Linux/Unix. Yes, there doesn't seem to be one, at least not for relatively recent Windows or MacOS X versions. And it's highly unlikely that someone will provide ...
