- Hi, Roy Brown , on 30-Mar-96 22:19:18 you scribbled....
- >Hi Mike,
-
- >I noticed that you wrote about Re: RAM in A4000/30, and I just had to reply
- >thus:
-
- >>>What kind of ram is used in A4000?
-
- >> 72pins with (36bit) or without parity (32bit) (doesnt matter)
- >> single sided are easier to fit ;)
-
- > According to my manual, singled sided are the *only* type that will fit

-
- this is a matter of size/space ...not electrical...
-
- >> 1,4,or 8 megs

- > Again, according to my manual, you can only use 1mb or 4mb simms on the

-
- ok, in full
-
- for fast ram on the MB:
-
- up to 4x 1meg simms or
- up to 4x 4meg simms or
- up to 2x 8meg simms
- ^^^^
- tried and tested (the MB thinks each of those 8megs simms are 2x 4meg simms
- hence the limit of 2x 8 meg simms ;)
-
-
- >> (but you can only have 16meg (fast) total on the motherboard, not mixing
- >>different types..need more mem - get a processor card)
-
- > Ah, you got this bit right. ;)
-
- >> comprehensive enough? :)
-
- > Yes.... but not entirely accurate. ;)
-
- MORE accurate than the manual ;)
-
- Also, did you know you can mix CD audio with the amiga's output via a few pins
- on the MB? (this is vaguely referred to in the manual page 4-9)
-
- BTW I'm also known as "the mad MB hacker" on account of me soldering more ISA
- slots in when I had a bridgeboard (both on A2000 and A4000) which worked fine
