Just a couple of quick questions:
1. What's the best (least expensive, easiest) way to expand an Amiga 1000 to
1 Meg?
2. What kind of memory chips are needed for the starboard memory expansion?
I know nothing about Amigas, I'm asking this for a friend who has one.
Please post responses to comp.sys.amiga since he can read the posts but not
post.
Thanks,

Depends. The least expensive is not the easiest. Probably the least
expensive method is to get an internal memory expansion, such as the
Inboard or Spirit. The easiest is a slap-on-the-side deal like the
starboard.
yun-fong> 2. What kind of memory chips are needed for the starboard
memory expansion?
The starboard takes standard 256kX1 chips, the same kind you stick in
a garden-variety AT clone. I think they have to be at least 150 ns,
but they might have to be faster. I bought some used memory chips
that came from an old AT clone and they work fine in my Starboard.
If your friend (or anyone else) is interested in purchasing a used
Squeeze-RAM memory board (adds one meg of memory at $C00000,
autoconfigures, installs internally between A1000 motherboard and
Kickstart daughterboard, has worked fine in my A1000 for two years)
then drop me email or call me: (415) 335-1503 (w), (415) 759-6590 (h).
I'd let it go for pretty cheap.

It will hold up to 2 Mb but can be ordered with 1 Mb (or 512Kb I think). Incidently, I have both the Minimeg *and* Insider on my A1000 with no problems (although Insider can be tricky to install).

The least expensive (if you have the skill or know someone who does) is the solder in piggy back mod as outlined in an old issue of Amazing ... This method is by far the most difficult and time consuming but it is hands down the cheapest route to bring your A1000 up to one meg (autoconfig also with Dave Haynie's mod).

Ok, I've been off the net for a while, so I just wanted to repost this: I've got a NEW MEGA-AMIGA MEMORY EXPANSION for the 1000 that I won at the 0th BKDC contest a year ago. I tested it when I got it, but have NEVER USED it. I don't want 16-bit ram, as I've got a FRANCES/LUCAS board now, so I want to sell it. It should also work on a 500, if you don't mind putting your 500 on a book and having the memory's power led face backward. The thing's a good-looking, well build board with its own power supply, so it doesn't tax your amiga's. It auto powers on/off with your machine so you don't have to switch it on or off manually. (neat) It has no pass thru, so it has to be the last thing on your bus. That's about all I know. It's looks well-engineered, and worked great when I tested it. Make me an offer. Best offer walks away with it. ( U pay shipping ). Since I don't check my account often, best to reach me by phone (415) 527-WARP (berkeley, california) any time is ok. -vince

I am planning to expand my 512k Amiga 1000 to at least 2 megabytes. Could anyone recommend a good memory board or warn against the ones to stay away from. I realize that this subject may have come up before on the net, so please E-mail your response. Thanks. -subrata

It will give you 1M chip ram, relocate your existing 512K chip ram as fast, and allow you to (eventually) have 2.0 in ROM while keeping the ability to KickStart into 1.3. This will give you a 1.5M system (1.75M if KickStart is in ROM), plus all the benefits of the ECS. This will tide you over until you save up for a 020/030 accelerator card with 32 bit fast ram. > > -subrata -- Fred Hamilton Any views, comments, or ideas expressed here Harris Semiconductor are entirely my own.
