- Well, Marc, since you know so much as to how to build computers (you
- are always saying we don't do it right, so you must know more than we
- do) why don't you do something constructive for the Amiga and the Amiga
- users such as yourself and build this device? I mean, you have even
- said it was so simple and "totally feasible" to build.
-
- Now, I can not say it is 100% impossible to build an AGA hack for the
- current ECS machines. However, from why "little" I know of the hardware
- involved, it will be rather hard to do. In fact, it would be more
- than just rather hard. Best of all, it would cost a rather healthy sum
- for such a device and with the 68040-based A4000 with 6meg of RAM and
- a 120meg hard drive selling for under $3,000 (street price) it does not
- sound like it would be a very cost-effective device for the users...
- Unless they already have a 68040 board A3000 and wish to use that, but
- you are saying to replace the CPU board... Oh well, guess I have to have
- a 68030 and throw away that 68040...
-
- But then, why would you want "AGA" in the A3000 anyway? You have already
- stated that you do not like the A4000 because it is simply an A3000 plus
- 68040 plus AGA and that it was a "kludge." (Your words, sir, not mine)
- So, if that was so bad that you think the A4000 is not worth it, why
- would anyone spend money on the A3000?
-
- But then, Marc, why am I even writing this? After all, you are really
- not worth it...
