These are perfectly compatible my friend. In fact they are the best EPROMS that I've used and never had any issue with them.

I also have them on 120ns as well :D
 
Hi Marios my friend.

Great news!!! Time to more experiments :D

All the best

3.9 roms for A1200 with boing bag stuff embedded

3.9 roms for A1200 with boing bag stuff embedded

I heard that someone here mightbe able to produce for me some 3.9 roms for the A1200 with the appropriate OS3.9 and boing bag 1 & 2 additions to the roms. I own a legal OS 3.9, OS3.1 and legal 3.1 Roms. Is there anyone who can produce these for me? I have neither the time nor epromming equipment myself. Any help would be greatly appreciated. PM or Post here.
 
Hi Marios,

I made some test with the Toshiba TC574200D-120 and I agree with you, these EPROMs are the best ones I used. :thumbsup:

For now I updated the A500 (with KS switch) and the A600 and both works great :)

Tomorrow I will try with the A1200 and the A4K's..... :coffee:

My best wishes as allways my friend

Hi again,

Well, my first A600 1MB ROMs works.

Now KS boot screen shows: 3.9.1 / 45.74

Classic WB & WB 3.1 also run good.

but.....

I receive all times one window request with: Insert Volume ENV in any drive.... :blink: , jut clicking on Cancel, all boots without problems.

Any idea to solve this issue?

You all may be interested with RemApollo 1.8 version. What is interested in this version that supports 1MB ROM. But so far no one knows how to prepare kick to work - even autor do not remember well, too. Here is a link for download remapollo1.8
and for version 1.7 wich one is requested to upgrade from it : remapollo1.7
 
Thanks for sharing Tomski mate.
Does it requires a special version to be able to kick an 1MB ROM then?

The 1MB ROM procedure isn't something peculiar. It works just fine on burned EPROMS and Loading it via WinUAE.
 
Just finished putting all my ROM updates in my new Deneb card and now it boots as a full 3.9 machine :thumbsup: No need for a custom EPROM anymore and far easier to update as well.
 
I've now tried a couple of times burning a regular Kickstart 3.1 (no extra or replaced modules) for my A4000. But they just won't work in my A4000, no boot.

I ripped my Kick3.1 from my A4000 with "transrom >ram:kick31.rom"... tested the rom with WinUAE and it booted to kickstart screen as it should.
I ran "SplitROMIMage kick31.rom SWAP" and it created 2 files:
- kick31.rom.hi (256kb)
- kick31.rom.lo (256kb)

Those where then burnt with my Willem parallel burner and they burnt/verified OK... but no boot when put in my A4000. (I've tried the HI/LO in both sockets, still no luck)

Is there anything obvious I'm missing here? :unsure:
 
first of all... it seems that you want to make a copy of your ROM right?
If so... then why don't you just take the ROMS and perform a READ on Willem and then WRITE to an empty one?

Anywayz... procedure seem just fine. I'd suggest to not use SWAP parameter and instead, use the ByteSwap procedure through Willem.
 
Yes, I want to make sure a plain copy of a 3.1 ROM works for now....
And when I'm sure that works I want to add/replace modules (perhaps make a 3.9 ROM).. so I would like to use all the required programs so I know they work and I learn how to use them :)

I'll try byteswap within the burner program instead...
 
Also don't forget that the EPROMS need to be at worse 120ns of speed.
Anything slower than that won't run on the Amigas.

I definitelly suggest some Toshiba EPROMS that tend to be really resilient. AMD's are ok as well though.
 
Still no luck in burning a rom I splitted myself :(
I tried doing the byteswap in the burning program but that didn't work either, still no boot.

I also tried to read one of the original ROMs and then burn it directly from the buffer.. and that works. It boots fine then...
So clearly I must be doing something wrong when splitting/bruning my ripped ROM :unsure:
 
Hi,

Under Remus, select "Split & Swap 16 bit" then burn directly the .HI & .LO files.
 
Ok I was thinking one thing....
- 27C400 is an 512KB ROM
- Amiga 4000 uses 2x256KB ROM.

So... MAYBE the problem is that the ROM needs to be full (not sure about it) but I'd suggest to double the info to it.

For example to make a dual Kickstart with 1.3 and 3.1 you need to double the 1.3 (being 256KB) and join it with the 3.1 (being 512KB) to form the 1MB ROM to burn to an 27C800 EPROM.

I'd make 2 tests if I were you.
1. Make the ROM (512KB) then double it on the Amiga and the SplitROMImage it and burn it.
2. Make the ROM (512KB) then SplitROMImage it and then on PC, double each file and burn it.
 
@merlinkv
Just tried that... still no boot.

@mfilos
How do I double a file?
