you can probably still get dreamcasts on ebay :), but those lack storage, so |
9 |
you end up having to do everything over nfs which is slow (even w/ethernet). |

i don't think you can buy lantanks anymore. even when i picked them up, they |
12 |
were being replaced by newer models and moving away from SuperH. you can |
13 |
maybe check out this page: |

i do have a dev board that i never ended up using you could have. |

honestly though, the fastest SH4 ever released is dog slow and they never |
19 |
really added a lot of RAM (the lantanks were like 266 MHz and only 64 MiB of |
20 |
RAM). you'd have a better time i think running in QEMU. |

even if you do manage to procure some hardware, i'm not sure learning SuperH |
23 |
is worth your time. it's a dead architecture. the people making the silicon |
24 |
(renesas) have stopped investing in SuperH ... their new "SuperH Mobile" line |
25 |
of processors really have an ARM core and just take their old peripherals |
26 |
(serial/spi/etc...) from SuperH and bolt them onto the ARM. the people |
27 |
maintaining the kernel/toolchain ports have put it into maintenance mode. |

if you're interested in getting into the embedded space, then i'd recommend |
30 |
looking at either ARM or MIPS. the former is super easy to get into -- just |
31 |
buy a Samsung Chromebook 2 for $320 :). there is an older model for $250, but |
32 |
you really want the new one performance/spec wise. |
33 |
|
34 |
other ideas perhaps worth exploring: grab some of the new embedded arches that |
35 |
lack Gentoo and do a new port to it. microblaze is in the kernel and the |
36 |
toolchain and is itching for someone to do the footwork :). |
