Unfortunately my first pc gave up the ghost quite some time ago. A Tanden PCX 20 4.77 mHz 8088
Shipped with 256Kb (yes 256Kb) but had been upgraded to 640 by the time I got it. Eventually the floppy controller gave out and by that time no one I knew had a controller for a machine that old

.
Served me proudly for many a year, amber screen and all.
Fondly remembered hope she is in a better place now.
