A4000 Mediator - Page 5

trixster · 03 August 2022, 13:22

Thanks for the kind comment. I bought this machine in 2016 from a local ad, luckily for a relatively small sum compared to today's prices. The machine was in great condition and the previous owner had had the varta removed and the small amount of battery leakage professionally repaired. The machine has been perfect since.

I always wanted a 4000 and remember seeing the picture Amiga Format published of one in their 1993 Good Hardware Guide Special. It looked completely amazing, so when i got back into old computers about a decade ago i decided i'd see about buying one.

These machines were made to be expanded, so that's what I've done

A BFG9060 has arrived

A314-CP now added to the clockport of the Prisma - provides the PiDisk for wireless file transfer

Hey trixster.... Happy new year to you.

How's the 0ld girl running these days? (13 months on)

This is still an awesome thread to read for 0ld School Hardware nutters like me.

Hi mate.

Yeah the machine’s running well, still 100mhz with the BFG, it hasn’t missed a beat. The only addition since the (amazing) A314-CP is one of arymanx’s excellent metal sfx psu mounts (https://www.amibay.com/threads/sfx-p...4000d.2440471/) and an a.mi.goun Corsair atx adapter (https://www.amibay.com/threads/a4000...4#post-2484284)

These really tidy up the airflow under the sfx psu and remove a lot of unnecessary cabling.

Other than that, nothing new to report. I think the only thing I’d consider adding to this machine is a half-length Re4091 were someone to invent such a thing as scsi would be a significant improvement over ide.

I'm looking at an upgrade possibility that will make your best Amiga look like a clown Amiga. Then I will hold the title of the best Amiga. *drops gloves*

trixster · 12 January 2024, 13:41

I look forward to the details, sir!

Aye.... SCSI takes a lot of CPU loading away. Warp 060 @ 100Mhz not an option for you?
On board SCSI then.

trixster · 12 January 2024, 14:11

I was reluctant to run the WE at higher than 80mhz for long periods as I didn’t like the overclocking of the board’s logic chips to reach 92 or 96mhz, plus the BFG has significantly faster memory access speed than any other 060 accelerator out there. This memory speed makes a big difference when comparing a BFG to other boards.

The other show stopper is that the Mediator stops the scsi working on the WE! Details are in another thread here on eab, and confirmed by Wrangler.

grelbfarlk · 12 January 2024, 14:38

And yet I have two Mediators with Warpengine/060s and they work fine.

trixster · 12 January 2024, 14:45

yes, it's odd, can't explain it.

Details are here, about post #23 onwards. We have to remove the L jumper to get the WE to boot with mediator. the affect of removing the L jumper is it disables the WE's rom which in turn means scsi wont work amongst other issues.

The drive attached to my WarpEngine seems to have decided to eat itself again for the sixth time. I have given up trying to explain why this keeps happening but I maintain that the WarpEngine SCSI is still second to one.

Second to none in killing your drives apparently, which IMO means it does not work.

My CS MK3 was killing the attached SCSI drives immediately after proceeding past the early boot menu. (several different devices lost their RDB repeatedly on two different machines)

Replaced MMUlib with original CPU lib and it started working perfectly again.
(Possibly I had not selected the ‘do you have a phase 5 cpu card’ correctly?)
