With a 2-4MB PCMCIA SRAM card it'll be perfect, and with that 68010 mod it's probably the only way you'll be able to add more RAM. Put in a 3.1 ROM (or custom EPROM) and a 4-8GB CF card for the hard drive, an
RGB S-Video adapter so you can hook it up to a LCD TV (unless you have SCART), and get
a couple of brand new control pads, and you'll have the ultimate little Amiga games machine, which will be fully capable of running plenty of decent productivity software too.
