Re: shorten basic files saved to wespi
I haven't checked the poke. But you have to execute NEW instead of clear. There is a way to reduce it without retyping: Reduce RAMTOP to 2K and new. Now you can load from wespi. After this execute CLS, then save again. The ZX81 collapses the screen if less than (not exactly shure) 3K of RAM is avail...

Re: shorten basic files saved to wespi

Re: EPROM suggestions
There are w27c512 eeproms with EPROM pinout that I often recommend. These can often be reprogrammed and about the waste: It's the question of price per piece and not 8k against 64k.

This is the display driver device name.
There are several display with various sizes available.
Make sure it's 320x240.
I have a 3.2 inch which is very readable and a joy to work with. I saw 3.5 inch, but not at a reasonable price.
