Hi Jan, Your VT52 term works also nicely, as it can cope with many ANSI escapes. I use your earlier version `qlterm v232'. I've added some features in the meantime such as 512x256 in 8 colours on SMSQ/E. Possible to open port with handshake, i.e. SER2HR rather than raw SER2IR? Actually not sure if ...

What emulators would you recommend for QL end, I wish to test something simple, not PE driven for a start? You might want to try QLTerm, it's a simple terminal emulator supporting ANSI. It allows redirection of the input channel which enables it to work as a Telnet client when running under an emul...

Typical non-Minerva applications that make use of the second screen need do the following: ⋅ Allocate any needed memory from the system ⋅ Go into supervisor mode and never leave it again while the second screen is in use. Note that implies that your program will take over the ma...

Bottom half seems almost writable by a program, I wish to decompose the rest. At the top I can most likely see system variables, there comes somewhere superbasic area, QDOS stack. I wonder what is that piano keyaboard pattern, that looks very regular? The thin lines are the slave block table (8-byt...

Defining your own traps is fine for jobs, but would that be a good idea for a global device driver? Probably not, but that wasn't mentioned in the original post. Speaking of which, I recently discovered such a thing in the SD card driver for the Q68 supplied with Minerva. It was a TRAP #14 in the r...

Darn it - I thought I had researched thoroughly :-) So, what does it mean I wonder when the Guide states 'Therefore, all reads of the status register are emulated.' Does this mean that MOVE SR, <ea> can be used and, if it does cause an exception due to running on a later processor, that SMSQE will ...

I’m working at editing the 6850 driver I believe you wrote to work with a 68681-similar device. It’s tough going but I am making progress. I don’t suppose you have a commented copy of it? :D I don't know which version you have, but I believe the source on GitHub is reasonably well commented? https:...

I also had one of the very first USRobotics HST modems in 1987? It got destroyed by lightning in 1989 or 1990. I just googled it and they still sell a model in the exact same style, but supports 56K - I think mine topped out at 9,600 HST. I bought my first USRobotics in 1990, this was a 14400 HST m...

This is an enquiry about the current state of play with the filing system on the QL, and the realistic or unrealistic prospects for an improved FS. One of the issues with Qdos is it uses a block filing system. As the system grows beyond anything Sinclair imagined in 1983, the blocks consume more an...

Hi Peter, I still don't quite understand what you mean. In the QL modes, the Q68 creates rectangular "QL pixels" that are 2x3 screen pixels, so the complete 4:3 flatscreen area is used. I assume most CRT monitors used with the QL were also 4:3 in geometry - and the picture also filled the ...
