Strange A590 mod

[Lurch]

Trying to work out the mod that's been done to an A590 PCB before I go connecting power to it ;-)

Photo attached, seems to run from the memory jumper to a a chip I can't quite make out. Will be probably remove it.

First A590 I've seen with it, plus it doesn't look like the blue wire and has a lot of glue stuck all over it which you can see in my crappy photo.

Ah well will have a play on the weekend.

Not sure if it's working, was marked as bad. Trying to get a working A590 from this PCB and my old one which decided to melt one of the memory chips.

Will find out today when I get home, if all is good I have some V7 ROM's and some new RAM on it's way.

If not it's back to hunting for a working A590, was offered one for 75 euro's but that's more than I really want to spend on it.

For less than €75 you could get the superior GVP Impact II HD8+

LOL Cheapest one I've seen is $110 euros + shipping on that

Anyway the RAM works on the "new" A590 PCB, just need to suss out a scsi HDD and the new PCB has a different power connector for the HDD so will need to sort out what to try there.

After looking at it closer the new PCB is using a standard molex connector were the old PCB was using a weird Commodore connection.  The power connector has the strange connection at one end then the molex connector at the other, so will just swap the strange connector over to a molex connector and see what happens

On another note if I put in a larger than 4GB HDD and partition it as 4GB would there be any issues?

[Lurch]

Nope. There's a chance it will be recognised by HDtools as something entirely different, but just correct those figures until they represent the correct values.

For example: I have had an 20 GB drive I used for testing showing up as 60 MB. After partitioning (which took a while to figure out), it worked without problems.

Nice, that's good news as I can get my hands on some cheap drives but they're all 37GB. Have to purchase a 50pin to 68pin adapter though but they're pretty cheap

Thanks for the NFO Jiffy, just worried about the power adapter but will find out tomorrow when I give it a shot :-)
