Found Commodore/DKB A4091 SCSI controller

[8bitbubsy]

Not much to write here, I want to buy one (working or not).

 

[davideo]

I might have a spare 4091.

I'll check in my boxes of bits tomorrow night.

Be sure to keep me updated

I've checked and unfortunately I've only got the one 4091 so don't really want to let it go - sorry.

What i have got that I inherited with the 4000 I bought a few years ago though is a GVP A4000 HC+8 Series II card.

This is non-working and the previous owner has attempted a repair on it. I've never plugged this in because I wasn't sure of his skills

If it's any good to you - you can have it for postage.

I'll give it a chance (the GVP), sending PM.

 

[davideo]

And replied with approximate postage cost

Piccys as requested.

If you look through the blurred image at the chip near J2 - this has a broken track to the chip. It has also been off at some time and refitted. There are a few shorts on the soldering - which is why it was shoved in my box as a "I'll sort it out one day job".

Also one of the clips on the RAM sockets is broken.

[8bitbubsy]

Thanks

 

[davideo]

You are welcome.

I hope you can sort it out

I don't think I will get this posted tomorrow but I should get it posted Friday for you.

Do you want this thread marked as Found or do you want to hang on and see if a 4091 turns up?

Dave G

 

[8bitbubsy]

I'll keep the thread alive to look for a 4091, after all I still want a super fast SCSI card for my A4000. The GVP might do if I can fix it, but it's far from as fast.

 

[davideo]

No problems and thanks for the payment

@8bitbusby

As promised this was posted today.

I slightly overestimated (guessed ) the postage - I'll stick a small refund back into your paypal later tonight.

I hate to state the obvious but before you plug this in and apply power - check the board out and make sure you're not gonna damage your Miggy with it.

I have a a Commodore A4091 Rev A card I was just about to list here, would you be interested?

 

[8bitbubsy]

Nah, I decided to not get an A4091 after all. I'll probably do with the card I got from davideo.

Has this card arrived yet?

Dave G

Yep!
I bathed the SCSI chip in SMD flux, resoldered the pins and wire-patched the main damaged pin. I also found two pins shorted on the chip --I carefully bent them back perfectly. Lateron I glued back on the broken SIMM clip.
It works great, I even burnt out the latest official ROM on an EEPROM for it.

Thanks a lot!
