**Need Setup HELP** with Classic Amiga 2000 HARD DISK (Bridgeboard)

[wbrejnia]

Darkage,

I haven't heard from you on your offer or at least on how  make the Multi Kickstart on A single Larger  EPROM.  I assume the Large EPROM has more address pins and your convert down the the 40 Pin Motherboard IC Socket.

I guess you are busy or away.

However I since I'm getting a full refund on the Other Switcher, and I can return all the parts, I've decided to go with one of these.

It's the Circuit board I'm after.   Made for Music ROMs. But Sam 27C400 EPROM /pinout as a kickstart ROM.

 I'll mod it with a Couple of Nand Gates to buffer the switch, and also the switch to not be noisiy with the Mhz Frequency of the CS pin.



Plus I'll have I'll 4 of my Original Kickstarts Installed (which will be better then sitting in a box).

Darkage,

I guess this is the way you mention you use.
Larger EPROM to fit 4 ROM images and select Address Banks by flipping Higher Address bits.



I ordered the other one since I want to finished my Amiga build this year.
PLus (if I decide to sell the Amiga Someday, it will be nice to have 4 Real Licensed roms inside)

Lost over a month waiting for the other switcher, so lost all my patience.

GOOD NEWS (BAD NEW - Lesson Learned)

The Good news is the Kickstart Switcher is at local post office, I got a paper notice for pickup.

THE BAD NEWS is my 1 TB hard drive on my Desktop Computer CRASHED.
Making a clicking sound and gone.

My last backup was March, so I lost about 10 Pages of documented progress. (( AT LEAST I have this forum as backup))

I do backups every 4-6 Months and (Photo's/Important STuff) I store in two places (so not lost)

Can't wait to pickup ROM Switcher and see if it works (unmodified).

The BREAK from this Amiga Project was kind of good.
I got that Controller Built and installed on my Fish Tank.


Even Had time to add some Special Effects and Lighting for Alerts, Notifications and Status.

[[ The base lighting was discovered by accident. I had a single LED to top, and the Base I just used a scrap piece of Clear Acrlyic that was the right size ]]
[[ While mucking around, the LED on a wire fell off, behind the Acrlic. It lit up the base, and I liked it. So I drilled a tiny hole into base and installed LED there ]]]
Pretty amazing when Flashing and switch colors during Run Modes ,etc .


Now my Tank is 90% Automatic, so more spare time...

Maybe I can get this AMIGA project back on track.

Here is the Switcher

So the Unitech Switcher that got Lost in Transit from Australia would have been easy to mod, since board circuitry was exposed.

The new switcher from UK (which arrive in a week) is painted over.
I should still be able to use a multimeter to figure out what pin is switched (OE or CE).



I would be thrilled it the Switcher works with all 4 ROM as is.

[wbrejnia]

Switcher Works (Just as I expected)   ** WON'T Work with mechanical Switch and Long Wire **



I was happy that the Switcher Board FIT into the Amiga.

But I was very disappointment at first when nothing would work (wire and switch).  Thinking it won't work at all.

Then I put on a SHORT JUMPER and it worked.

So as I thought, the Frequency of the R/W access is too noisy for unsheilded long wire and mechanical switch.

At least it works, and now I'll try shorter wire, and if needed build the Nand-Gate Switching module, which will install-piggyback onto the board.

[wbrejnia]

WOO HOO!! Short Wire Works.

I quickly just did a short wire, and put two ROMs in.

WORKS!

[wbrejnia]

INTERNATIONAL (UK) Issue (Left vs Right)  ** ROM Switcher Works 100% **

Duh!!!

I was in a rush to pick up kids.
I assumed ROM1, on rotating switch would be FIRST-LEFT Position.
We drive in North America on Right side of Road, Maybe similarity to Driving on LEFT-SIDE in UK switches go 4,3,2,1? I have no idea, this switch is backward (and No template label)

And since I only had 1 ROM installed, I was selecting ROM 4 (which socket was empty).

Of course with Jumper, I picked the right connector (#1).

So it works perfect (as Shown Below)

Finally a well deserved break



One thing I noticed is with the Wrong ROM my Hard Drive with Amiga OS3.1 crashes (With for example Kickstart 2.0).  

I disabled the AutoBoot on the Hardrive Controller.

That will be an easy fix:

-> Multiple Partitions
-> Boot from Gotek as needed.
-> User the DOUBLE-MOUSE (Auto Boot Selector)
-> Other ways when I play with combinations.

I can now move my Amiga off the Workbench onto my COMFY DESK for the Software Install/Setup Portion of this build.

FUTURE (Amiga SideKick Module) Feature

I got an idea.

I keep talking that I'm going to build that Amiga SideKick Module.
It will be a simple box with buttons that will do some INTELLIGENT control things for this Multi-OS, Multi-CPU(AMIGA/8086) Computer.

Similar to making that Gotek LED display driver, I will use that Ardiuno Nano controller and do some Pre-Configured Mode switching.

I can modify the 4x ROM switcher and replace the Mechanical switch with some Nand Gates and switch with the Ardiuno.

Similarity if needed I can turn off AUTOBOOT jumper, control Gotek, PC Hard drive, Lotek Adapter, IDE-SD Card reader, etc ,etc, etc, etc

The nice case for the Side-Kick that I found on Alixepress is SLOWLY on it's way.

More details to come. First I have to setup OS's.  Know the combinations that work (Ie bridgeboard, Which ROM, which OS, which config)

[wbrejnia]

So the DrumKit ROM switcher works fine as an 4-ROM Amiga Kickstart Switcher, even with Long cable and Mechanical switch.
https://www.circuitbenders.co.uk/forsale/RROM/kawaiRROM.html

It was the Left-To-Right thing and incorrect ROM placement.

The Wire reaches the rear card slots, so I'll take the plate I made for the VGA Indivision connector and install the switch at the back of A2000.

Now I need to figure out how to backup my GVP Hard drive.  (Maybe onto Gotek, or if I get Bridgeboard working, transfer onto PC side IDE-SD card)
The GVP Hard Drive came with some pre-installed Software which I don't want to loose.  OPUS, Paint, etc.

And the Seller partitioned the 2nd Partition for the whole 500MB,  which I want to break up into multi OS partitions. Partition one is OS3.1 50MB.

The hard drive also comes with Amiga Backup program, but it only backs up onto DF0.  COnfig thing I need to figure out.
Plus I am worried about using it, since the Backup image is compress-proprietary and to get back files, you need the backup program.

Amiga ACCELERATOR Arrived (Won't be needing a Vampire Card )


Yup it finally arrived from China.



Well, at least it will be good for WHload, when I get around to installing.

Never pulled out a CHIP this long.  Should be fun, if I don't crack the 68000.

I will be restarting this project, hopefully soon.

[wbrejnia]

The Photo of my ROM switcher Testing dissapeared from the Post above.

This is where the project stands now.



Basically I need to start install the Various Workbenches (Either on Hard Drive Paritions, or Gotek) and see which ones I can get working with my Bridgeboard.

[wbrejnia]

Shoot!!!

I peeked at the Motherboard.
The Amiga 68000 CPU is much larger then the 68010 I got.

I never knew they came in different sizes.  (What is the part # I should be looking for, for proper 68010)

Oh well the 68010 was only $5

[wbrejnia]

NEW Phase of A2000 Build Project Starting (Multi-OS, SW install, and SideKick)

HW build is done, so Moved A2000 & Explorer off my workbench and Onto My desk.

Much more Comfortable.  No more standing for hours.
Get to watch the Fish Swim while I wait for Slow stuff to happen.



Also the Case for the AMIGA "SideKick" arrived from China.



This is the box (Matches nicely with Amiga Color) that will have some Automation to Run the Amiga.
Not sure exactly how, but time will tell.

So first step is to backup current Workbench 3.1

The build multi Partitions for each OS and figure out which Kickstart's I need.

Top Priority is to ensure Bridge board Works.

I ALSO found a Proper 68010L8 CPU (Sufix must be L8 to Fit into Amiga)
China wanted $60 US, but then I found one in a Bulgaria Electonic Supplier for $16.59 US (Shipping $6)
http://panda-bg.com/bg/product/%D0%98%D0%BD%D1%82%D0%B5%D0%B3%D1%80%D0%B0%D0%BB%D0%BD%D0%B0-%D1%81%D1%85%D0%B5%D0%BC%D0%B0-MC68010L8-DIP-64/040191/

And a while Back I won this InfoCom Treasures Package on Ebay.
This will bring back some Good Old Memories.  Plenty of games I never tried.



I know for sure, and I tell my kids, that my excellent problem solving skills today are because I played the Infocom Games a lot, and enjoyed solving them.

[wbrejnia]

Proper 68010L8 CPU arrived.

This one came all the way from Bulgaria.  Price was resonable for Brand New.

Much better then the last one.  Looks like it will fit.

Project is on Hold with Busy summer.

[wbrejnia]

Summer break is over.
 Kids back in school.
 
 Getting the itch to restart and finish this project.

[wbrejnia]

HI Mashmalow,

Good timing I just finished my Fish Tank Project

I need something to do.

I will help you.

I will power up my Amiga & Bridgeboard tonight, and remind myself what worked. (I kept my one Floppy where it worked)

If I remember correctly, It worked with SD card, but not with Compact Flash.
Let me double check since that testing was long time ago.
 
 My name is Wally.
