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...

Re: Redesign Electron Plus1

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...

Re: Elite in ROM??

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...

I must go back to investigating the Electron PSU. As capable as it is, it’s working way beyond its design specifications. So a replacement, I think, would be appreciated by users who like expanding :mrgreen:

Re: Which Gotek for a Plus 3?

I’d visit Mark at RetroClinic. He can provide you with a ready Gotek. Either email him or visit his eBay shop.

If you want to add the Gotek as a second drive you’ll need an adaptor which you can pickup from Dave H. He also has some other upgrades for the Plus 3 like ADFS with PAGE at E00.

Re: Just bought a Plus 3 and problems

Gotek is the best way to go. Dave H on this forum has an adaptor to add a Gotek as a second drive and has a version of ADFS with PAGE at E00 (useful for games that need more memory) which plugs into the Plus 3.
