Re: Trying to fix A1 CPU module

UPS from Florida to Israel including handling is 40$(it's resellers statement). However, if I perform a rework in US (alrady found a place there) I would order the cpu directly to the rework station. So that's not an issue.
And I suppose that 7457 isn't electronically compatible with 7455 and that makes 7455@933MHz from the reseller for ~290US$ as the only option. Total rework price would be <500US$, maybe even <400US$.
The only catch here is if the module itself ok. That's why I'm waiting for news from Adam. If I was patient, I would wait for 1.7GHz ones to be released and then get a 2-nd hand G4 cheap, but that means a used cpu module. 850US$ for cpu is too expensive for me. The ideal solution I would jump onto it right now us <=500US$ for 1.1GHzG4 (sigh)...

A question about compatibility between MPC7455 and MPC7457 G4-s:

7455 page states this:

"Offered in a 483-pin CBGA package, the MPC7455 processor is
pin-compatible with Freescale's MPC7451/MPC7450 processors:

7457 page states this:

"Offered in a 483-pin CBGA package, the MPC7457 processor is
footprint-compatible with Freescale's award-winning MPC7455/45 processors"

It isn't the same thing (At least doesn't reads the same) . Footprint indeed the same. But electronically? Number of pins and their geometry are the same too. But the layout(electronically)?
Can anyone throw some info?

It's not a bug, it's a thumbs up to the bugbusters

The response(actually the dissaperance of the bugs) is astonishing!

Meanwhile there's this confusing bit on prices:

I found at some surplus part reseller MC7457RX1267LC (@1267MHz) for 791US$UPS shipment, about 30US$ imho)

I also went to Freescale's online store and found a MC7457RX1267LC (1GHz, the only 7457 available online) for 248.88US$(without shipment/handling)

Go figure

Afair, there's some documentation on OS4 CD on how-to set up a firewall on AOS side (in Roadshow docs). I didn't try it then (and can not now). If it is useable, there should be a pointer.

I'm not sure about the A590 - I think this wasn't IDE as such but Mitsumi and the like. It would be very hard to find a CDROM with these interfaces nowadays!

A590 is XT-scsi combo + ram. As afar as I knew about it when I had one.

Just ressurecting this to see if any of newcomers (welcome!) are in this sad boat.
So far there are 3 of us (me and two more) that confirmed their situation. According to my and others estimates there should be much more.

Now that you have mentioned AREXX, I noticed that I should have explained myself better.
I intend to learn a language which I can also use on my Windows PC

There's REXX for windows too. Look for REGINA. It's user guide cover differences between numerous implementation of REXXes. Including AREXX. Actually I owe already about 5 years of work (not fulltime though but it counts) to knowledge of AREXX. During the interview I was asked (as a student then) which languages I can program, and when I said REXX, interview ended and I was in

Do you think learning C++ is too hard for a beginner? Are there any alternatives? Basic is easier, but might be too slow. The concept of the language is also a bit outdated I think.

C /C++ is the most common these days (imho). Pascal is probably easier to learn, but it's certainly doesn't come close to C++. All depends on your needs.

I would also like to know if there is a good editor that runs well with older Amigas. When I participated in the Java course, we had an editor that highlighted the commands and variables.

Golded is the most advanced imho. Full version is commercial though. I perfer CED for quick edits (no colour and syntax highlighting).
Otherwise there's Emacs (there's a verson of it for Amiga that doesn't require geekgadgets afair, but I might be wrong, When I get to my a1200 I'll try to remeber to check).
Vim is an option too.
There are more, but I prefer these.

Sister_Rita:

Do you intend to write with or without gui?
Imho the most intermedite language is AREXX.
Afait, it is part of WB2.0 and later or so.
There's an amigaguide userguide for it somewhere (aminet afair)

Good luck

According to Amiga hardware book, no (afaik).

However there should be some non-GVP.

An AT psu is easy and cheap (can be even free) to get and there're plenty of diagrams how to wire the A1200 power cable to it. However the fact that removal of the accelerator didn't help is a bad sign...

at the moment both my amigas's , a a3k and a a500/gvp 030 have un patched/modified wb 3.1 on em..

Great! Is that a GVP A530 expansion? I am using one of those too! With which processor speed is your expansion equipped? Mine has a 68030 processor running at 40MHZ.
In my opinion, this is one of the best hardware devices ever made for the old Amiga. Great Valley Products was one of the most respected Amiga companies.
Did you know that these expansions have become extremely rare nowadays? They are very expensive when you buy them second hand. You better keep the Amiga in a safe place.

Reminds me the old days when I had an a500+a590 (afair) with 2MB of ram and extra 0.5 onboard modded to be swtchable to act as chip of fast ram. 3MB in total. It First I had an XT 20MB HD, then dumped it for 40MB scsi one and felt like riding a race car. On the pain 68000. When compared to it, 386 with windblows 3.1 felt like pulling a cart with stones in it.

Nothing like that can happen under OS4. Even hacking utilities like NMAp can't identify
the host operating system, let alone try to attack OS4.

True and it's good. But that's easy. No other AOS had an open port (no tcp/ip stack). And I don't thing they (nmap) bothered collecting any identification of any network service available on AOS.

Quote:

Also, not having any open port by default, does certanly help.

However it's certainly not sufficient. Every protocol has to have the highest (if it is possible) security-wise level.

Quote:

For the record, I've been running an A1 on the internet for the last 4 years, with a STATIC ip address and without any kind of firewall.
Never had a "security" problem.

A bit paranoid look on this: it is good untill something happens

Is anyone running stock ( no patches or gizmos ) levels of Workbench?

I tried recently, here is what I found:

Workbench 1.3

ARRRRGGGHHH!!! God this is AWFUL. Like the busy pointer though.

Workbench 2.04

Ugly, more pro looking but really ugly and doesn't do much. No backdrop picture!

Workbench 3.0

Disgusting. How was I ever persauded to use one of these?

Workbench 3.5

Hmm, almost like a real OS ;)

Workbench 3.9

Getting better, works pretty well off the CD.

Workbench 4.0 ( AmigaOS 4.0 )

Now that is what I call a decent out of the box experience.

I don't entirely agree.
Appearance is a personal taste (I mean appearance besides the imposed standards/expectation of the specific time). Besides that every single AOS release brought in it's innovations (all of them except 3.5/3.9) or facelifts (3.5/3.9) that were a must when I look backward. Every single of them. And without any bloat. And that should be appreciated nowadays. And it was very Unix-ish OS when you take the multi-userness out, ant that's good imho.
