Re: BBC Model B+ video problem...
I picked up a Scart cable on eBay and it had the wrong resistor for sync 220 instead of 270. Lovely scrolling effect. Didn’t bother to return as I had another working cable. When I next pass an Electrical component store I’ll pickup a replacement resistor. For the correct wiring check out this page....

Re: Electron with Plus1 and Plus3
Key issues are not so uncommon. They can usually be fixed by pressing the key repeatedly, or by unsoldering the key, removing the legs of the key and cleaning the legs. I’ve done this several times. For the interference on the screen, I’d check the rf output to see if that has interference as well. ...

Re: P.R.E.S. Advanced BASIC Editor ABE - ROM and Cartridge
Still not working.
Procedure: *BE, Load program, type UTILS or Escape and it hangs
Tried with AP5 with BeebSCSI and with Pegasus with Gotek. I also tried swapping Elks. At the weekend I’ll try a Basic Electron with just GoSDC to see if there is an issue with the Plus 1 and AP6 combination.

To run the ABEs Utilities - Start BE with *BE - Load your BASIC program and then type UTILS Dave H :D I’ve tried that but no success. I’ll try again this evening to see if I missed something. BTW, once ABE is enabled I’m not able to change directory. I can load a program if I enter the full path.

Re: P.R.E.S. Advanced BASIC Editor ABE - ROM and Cartridge
If anyone is interested the ABE works just fine in Elkulator loading the ROMS into the two cartridge slots.
BeebEM, I'm struggling to get it to work with SCSI harddisk enabled.

Re: Reducing Basic Program Size
Static variable definitions also can be farmed out into a *EXEC file as immediate-mode statements; just be sure to start the program using GOTO as opposed to RUN which will wipe them out again. Neat idea. 10 CLS 20 PRINT'"Program begins"' 30 *EXEC INIT 40 END 50 PRINT'"Program contin...

Re: New Batch ROM / RAM Expansion Board for BBC B
Unfortunately not. The B+ already has most of the features that the IntegraB offers; that being the 20k of shadow RAM, 12k of private RAM and the 4 x 16k SWRAM banks (assuming you have the 128k model). I remember asking the same question a while ago. It led me into thinking what would be a nice and...

Reducing Basic Program Size
Does anyone have some tips about reducing the size of a Basic program to share? I have a program on my Electron which I need to almost half in size to fit in mode 1 on an unmodified Electron. Currently running it with a MRB. I generally know I should reduce the number of lines of code by combining t...

reading this topic for the first time. My thought would be, why replace the plus 1 with a new implementation? Why not build something that combines functionality of the Plus 1 and 3, AP6, AP5 and Gotek, for those that don’t have any extensions to their Electron, and have some type of all-in-one solu...

I think the sideways RAM version of Elite for the Model B loads once then doesn't access the disc again. Could be wrong. Not quite what you are asking but quicker than the original disc version. I've been searching the interwebs for a B+ 64kb Sideways Ram/Rom Module but have only found some for the...
