Dave Horsfall scripsit: Just so. The constraints are pretty tight. The GBA has 32K of on-chip RAM and 256K of off-chip RAM. Cartridges have 32M of ROM, so the system disk is stored in ROM with a shadow overlay in RAM. In any case there is no keyboard or other character input device: all it can do is run a preprogrammed set of commands in the shell. So running an ancyent Unixe on SIMH makes a lot of sense, since the device can never be anything practical. -- John Cowan http://www.ccil.org/~cowan cowan(a)ccil.org Assent may be registered by a signature, a handshake, or a click of a computer mouse transmitted across the invisible ether of the Internet.

I'm surprised that they chose Ed5, as Penguin/OS is normally the choice for weird devices. -- Dave Horsfall DTM (VK2KFU) "Those who don't understand security will suffer." It is running V5 in SIMH on the Gameboy. Pretty nifty, however, the ARM processor varient does not have a memory manager, so I suspect that it had to be something simpler then one of the modern systems. This wasn't a bare iron port. If you go to the page, he does not one of the early BSD systems running in SIMH on it too. -- Brad Spencer - brad(a)anduin.eldar.org - KC8VKS http://anduin.eldar.org - & - http://anduin.ipv6.eldar.org [IPv6 only]
