Apollo 1230 problem

macce2 · 07 May 2009, 01:01

I somehow managed to broke the eprom chip.
After that, the memory located in the board ( 8 Mb simm) didn't
show up. So, it was some kind of memory handler chip ?!?
The chip had "window", so I think it was eprom ?!
It was located in "socket", so it could be easily changeable, BUT...
-Where could I get one ?
HEELPP!

Btw, the chip is of 27CI28-2JL type.. If it helps anyhow.. ?!

I'm sure someone could dump the rom for you and burn you a new chip.

DoogUK · 07 May 2009, 22:00

Which model apollo is it? 1230 turbo or 1230 lite etc...

Chain · 07 May 2009, 22:05

Lite does not have EPROM, just a GAL chip

I can do a 27C128, piece of cake, but where to find that dump
(and what is worse macce2 is from andromeda galaxy, whoa, long way to ship it)

I can do 27c128's as well.....it must be the turbo then.

macce2 · 07 May 2009, 22:10

Yeah, I'm not 100% sure, but I do think it's not the lite version..it does have a 68030@50 Mhz on it, and a place for scsi module.. and I think it does have fpu and mmu, too.
If needed, I could send a photo and more information later on.

Oh, not Andromeda, I'm located in Finland :-D

DoogUK · 07 May 2009, 22:11

thats the turbo

DoogUK · 07 May 2009, 22:12

How is the rom broken?

macce2 · 07 May 2009, 22:23

Well, I must admit only a few chip pins (feet) broken..
I'm not sure if the chip itself is broke.
But I have no soldering skills, and would like to play it for safe.. :-)

DoogUK · 07 May 2009, 23:49

If you post me the rom...i will patch it up and copy it for you then send back the new rom.

macce2 · 08 May 2009, 00:48

@DoogUK

Many thanks in advance, for your very kindly offer! :-)
I guess youre into electronics, then... :-)
Where is Dorset located.. (Uk?) ?
I just need your address and contact information, then.. and the price you'll charge !

DoogUK · 08 May 2009, 01:12

Just postage and the price of the rom...and yes i'm in the uk.

I'll send you a PM.

macce2 · 08 May 2009, 01:19

ok, thx!

macce2 · 15 June 2009, 21:53

A friend of mine succeeded in soldering the chip (two new feet).
All seemed to be ok and I expected it to work, but- my Apollo doesn't seem to find any ram fitted anymore.. :-/

Is it possible that the chip is somehow lost its data..?!
o what could I do ? I'd like to try with a new chip, but where could I find it ? :-O
Well, s

Rabbit80 · 15 June 2009, 22:05

Any chance of some photos of the board?

@Rabbit80

Oh, sorry for the "incomplete" link..
But mine is just the Apollo1230 turbo, older version.. not lite or mk2.
I think even if my board doesn't have much different look than the standard one,
I'll send/upload(?) photos of it, if needed.
The chip I'm talking about is some kind of "typical(?!) eprom type chip, the socketed one near the processor chip, as you can see in the photos. (bigbook of amiga hardw)
The chip does have a kind of "window" in it..

Rabbit80 · 16 June 2009, 15:46

I see - I have the later version of the Apollo

Sorry

macce2 · 16 June 2009, 19:10

@Rabbit80
