Hi Zuiko21, i have got a spare IIsi i want to get rid off, i will keep the ram and floppy but probably not much else, if you want it you can have it for free... as long as you want to pay p&p from France to Spain.
I have tested it and know the psu is working properly, the disk was dead !!
Let me know, as i will probably get rid of it soon.
Un saludo.
