I need a clarification about that, the vlb slots they all share the same bandwidth so we have 133mb\s for all the bus, or every slot has 133mb\s to use? If it is the first option then yes a combo card is ok since the bandwidth is shared between all slot, but if every slot can use 133mb\s then (it's …

Just going by the pins... JP15 5pin pwr led & keylock JP14 4 pin speaker JP13 2pin JP12 2pin JP11 2pin JP10 2pin no idea, but there should be turbo button, turbo led, reset button & ... ? JP3, JP? JP4, JP5, JP?, JP9, JP? mostly no idea, though JP9 might be selecting between SIP and DIP memory.

Well, Ndc2012, we don't know what CLK2 is so.... if it's 33MHz (the cpu clock), then best to set it to CLK2/4 just like pc-sound legacy suggested already. Anything over 8MHz is already overclocking the poor ISA bus.

Well, you don't need them in the most cases, but regarding datasheet, you should still add them. I heard, that the in/out voltage could otherwise resonate against each other, which will lead to a very fast overload on the regulator. I didn't see such behavior yet myself, but some experienced guys …

True, but don't forget the capacitors.... Just as I told in my video, there is no THE solution, there can be many. We just made one, which is unusual and definitely has it's flaws, but still useful in many cases. If you need -5V in your retro machine, just plug it in. If you don't just remove it …

So Phil is still alive? Haven't seen him for ages on Vogons. Also, some cons of this design that come to mind: - Wastes an ISA slot - Misses further blocking caps of 100nf, 10uf etc - No heat sink, no fuse - The 7905 misses vital parts mentioned in the official 78xx/79xx datasheet! Diodes, caps etc …
