Re: New Minerva ROMs for Q68

Hello Jan! I've been playing with your Minerva4Q68 recently as we continue to develop the QL-Net driver for the Q68 (ND-Q68, already working under SMSQ) and wondered if you felt up to the task of re-assembling your patched Minerva to incorporate the 'I/O Fix' that Marcel added to Min v1.98. Effecti...

Re: TTY ANSI Terminal

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 ...

Re: TTY ANSI Terminal

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...

Re: SCREEN1 = SYSVAR @ JSROM

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...

Re: SCREEN1 = SYSVAR @ JSROM

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...

Re: How to reliably detect USER or SUPERVISOR mode across CPUs

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...

Re: How to reliably detect USER or SUPERVISOR mode across CPUs

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 ...

Re: Today I Received...

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:...

Re: Today I Received...

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...
