Yesterday I got my hands on what seems to be a very well preserved Epson Equity LT Portable PC (the power adapter is not original, but improvised using a Cisco switch PSU, but it works) - it looks just like this one:

It came with MS-DOS 3.20, but I wonder if I can upgrade it - ideally to MS-DOS 5.0 (is this the latest available on 720KB floppy disks?), if supported by the Nec V30 CPU. Other than that, I learned that pretty much is "fixed" on it (the 640KB of RAM, the 20MB hard-drive, no FPU socket), but I can't wait to put it to some good use 😀.
So, what's your experience with MS-DOS on ancient PC XT (8088/8086/V20/V30) architectures?
Thanks.
