Re: WANTED: Memotech Memopak RS232 Interface
It seems they are quite rare. I've never seen one on eBay the last 10 years I've collected Sinclair. I don't know if anyone on this forum has one. If they have, they would cherish it, and not part with it.

Re: Any other source of ZXpand+ ?
Well the main problem with the ZX-Wespi is that you always have to load a menu, and select your program from the menu. That does not work with programs, that loads another file.

Re: 90 degree card connector?
I bought these.

Re: Preferred SD Card for ZXpand+
I believe using the SD-Formatter program to format your card before usage is a good idea. I believe there is also an issue that firmware cannot be updated from a large SD-card. I think the firmware update might only work on a SD card formatted with FAT16. I cannot remember. I just know I have an old...

Re: Desoldering heat gun
I have one of these, that with an electro magnet suck once, and when you release the button, blows all solder out again. So it's not very good. However it's better than none at all.
