Re: Printer Emulation..(ie ESC P printer emulation)

Also, on Linux, there's "escp2topbm" as part of netpbm-progs It turns out this only works if the printer has been switched into graphics mode and a bitmap sent. For text interspersed with escape sequences to control highlighting it complains "no image". I don't know how useful it is to be able to g...

Hard drives in B-EM

How in very detailed steps are they set up for use with MOS 3.2?

The preview B-EM claims to have SCSI emulation, but no tools are provided to initalise them. The supplied HDinit.SSD image from 2.2 is not recognised by the current preview release (something I've mentioned on the Github for it).

There is and those lines are NOT present, which is odd given it's the config file in the Distro..
Checked and it seems an old version of the cfg got mixed up... Copied across the lines, and it all worked...

It would of course help is the current Preview build actually started at all - It doesn't for me at the moment, moans about no models being defined. So the models are defined in the b-em.cfg file.

Re: Designer Castles..

I don't recall any extra logic . I was using a Master at the time and Masters can take 32K ROMs. How does that work? I thought ROMS were 16K because of the upper 16K of ROM being the OS? You mean 32K Roms that appear in the Memory map as 2 16K slots? In using the Printware ROM on a Master128 I don'...

B-em..Current Build?

Where was a current build /distribution for Windows 7?

I was wanting to experience the improved version with the Music 500/5000 stuff in it., which isn't present in the 2.2 build on it's nominal website.

Anyone got a current Windows build of this?

Thanks

IIRC there is something funny about the ROM ( e.g. 32K ). I have memories of moding it to run from SWR.
BAnked?

I seem to recall some other BBC roms like Quest Paint had additional logic on their chips, Not sure if this is something current emulators can handle.

In B-Em it is possible to redirect the parallel port to the clipboard: pp.png You can then paste that into another application. I have only tried this with text, though.

The only reason the code isn't crashing in earlier BASICs is that the maximum string length is in any case only 255 characters so it gives up looking for the terminator before it gets past the end of the buffer you have allocated.
