The maximun power draw would be at 2,5V and then you'd need a step-up regulator to get the 5V that a P/S2 or USB mouse...

Were the CF card written using your Amiga or written with a CF reader on a modern PC?

A factor that hasn't been mentioned yet is what you have access to. If you have an empty eprom and an eprom programmer I chime in with those who suggest 3.1.

The perhaps ugliest of all ungly kludgy hacks to get both the 8MB expansion and an A590 to both autoconfigure would be to add a counter that counts clock cycles (perhaps the E clock to save bits on...

If you decide to build one yourself, I suggest you buy a decent (one of the thicker ones) scart wire at a thrift store. Sure, it's almost impossible to fit the wires in the mini DIN connector, but it...

My guess is that it's either ESD related or related to grounding of the Amiga and the soldering iron.

You should electrically connect the soldering iron with ground on the PCB you are working on...

Nice project!

This seems like something that could be done to hardware that uses those rare GVP SIMMs too, like for example the GeForce 68030 accelerator for the Amiga 2000.

Interesting discussion!

Re buffering the data: Back in the 80's and 90's you would had to use DRAM to get a reasonable price Back then DRAMs were typically rarely used by amateurs as they were...

It's a multi stage process.

Pressing ctrl+amiga+amiga makes the keyboard send a reset warning message. The computer can either answer immediately or defer the actual reset for a certain period....

Hi!

I'm pretty sure that this is the 14MHz accelerator I did build back in the early 90's.

I used the CDAC signal (or whatever it's called) rather than any analogue delay circuit to generate...

I hope it's okay to dig up an old thread.

I'm new to this forum but not to Amiga. This is the first thing I write on this forum.
