Love DOSBox on java, but don’t like java? Love the power of Google’s v8 javascript engine? Well then you’ll love this, introducing jsDOSBox, a port of jDOSBox to javascript!

That’s right, with chrome, it is as simple as click and go!

Doom in dosbox all in javascript!

So how does it perform? well OK OK, its slow, but it sure does have promise!  Then again it could be my laptop.  But wow, emulation in javascript!

Test it here.

OpenBSD 5.1 released!

I saw the announcement that OpenBSD 5.1 was just released today (May day release?) Anyways I thought I’d boot it up on SIMH to check that the VAX is still working. So here is a minimal ini file, that I used.

set cpu 64m
set rq0 ra92
att rq0 openbsd_vax
set rq1 cdrom
att rq1 cd51.iso
at xq0 bob
boot cpu

I fired up SIMH, and away it went!

KA655-B V5.3, VMB 2.7

Tests completed.
