Some recent experience that might be worth adding to the troubleshooting guide:
When booting SMSQ/E for the Gold or Super Gold Card and you end up with a non-working keyboard:
Reconfigure SMSQ/E for "ABC keyboard: none"

Re: 68060 based QL system?
I am specifically talking about devices that share the processor bus and are addressed in CPU space, and use the A line and F line instructions. So you meant the peripheral chips that used the official coprocessor interface of th m68k. Indeed , these were only the MMUs and the arithmetical co-proce...

Re: 68060 based QL system?
There were at least the 68440/450 DMA controllers, 68681 DUART, 68901 MPU and 68230 PITPr0f wrote: The original coprocessor architecture of the 68K was supposed to be extensible, but I only recollect FPU and MMU being made availabe, were there any others??

Re: 68060 based QL system?
MacOS is written in a high-level language, most probably C. Porting it from PPC to x86 involved "only" recompiling it on the new platform and "fixing a few quirks". Still, it took a company like Apple about a year. SMSQ/E is written in 68k assembly completely. Porting to a new pl...

Re: Hardware values...
Dave, retro computing stuff is worth what people are willing to pay and price depends a bit on how urgently people want stuff - An SGC is one of the most urgently wanted pieces of QL Hardware and is thus worth nearly the price when it was new to some people. Last few eBay auctions I have seen were b...

Re: Problem at boot time
For me this looks like a bad contact somewhere (memory ?). I had a similar problem, it went away when I moved the SGC DRAM chips a little inside their sockets. Same here. The RAM chips on the SGC seem to suffer from oxidation of the pins in the sockets over time. Wiggling them very carefully helps ...

Re: Mawdraw problem (easyptr4)
Giorgio,
the simplest way to achieve that is to create a bitmap of that two lines of text and put the bitmap in the menu.
There are probably better ways to do that, though.

Re: C1 Pascal
Here's another thread where I described how to create a Prospero Pascal programming environment for modern SMSQ/E computers using C68 make:

Re: C1 Pascal
Are C1 PASCAL and Metacomco Pascal (with the ROM dongle) comparable? From a language view, yes - All tree implement a somewhat standard Pascal with similar language features, although the QL-specific implementations differ a bit. The main difference is that C1 Pascal is not what I would call a true...
