- Ayup. The 040 bus is quite a bit different than the 030, and it is more
- difficult to design stuff to work with it. Most 040 systems have a bunch
- of high speed memory, etc., on the local 040 bus and then a generic bus
- interface of some sort to connect the rest of the peripherals to (Zorro III,
- 030, whatever...)
-
- Now assuming that C= has not produced two different 040 cards, is the
- connector ("Kel from Hell'?) and bus in the A4000 the same as in the 3000?
-
- If so, a 030 card for lower end would be fairly easy without having
- bus translation to do. Then, would it not be easier to make a EC030
- card for the lowest model computer than make an 020 card?
-
- The 030 and 020 buses are basically the same. An EC030 would be a good
- choice for a low end machine. I am continually amazed at C='s decisions
- to continue putting 68000 cpus in new machines (A600, A2500, etc., etc.)
- *Nobody* makes PCs with 8086s anymore, and there are *very* few 80286
- machines being made anymore. C= continues to crank out 68000 machines,
- though...
-
- (Are there even any Macs with 68ks anymore?)
