In the early 90's, I upgraded my A500 with a 68030 accelerator and 2mb
of 32-bit wide fast ram. The 2mb of ram, made up of the same 41256's
mentioned and some memory controller components, cost around $250.00. I
also purchased a dataflyer 500 ide HD controller. These add-on's really
helped extend the life of the machine, and really made it much more usable.
For what it's worth, I'm still looking for the (16) 1Mx4-bit DRAMs to
take it from 2mb to 8mb. I have some SMT ram that will work, but have
to create a carrier for them, and then have tons of soldering to do,
which I haven't really been looking forward to.

I have a very clear memory (no pun intented) of
spending $19.95 for *one*
256k x 1 (41256?) memory chip. I needed nine of the things to make a full
bank in my PC. This was around 1987 or so. It took a long time to fill
that bank of memory...
I remember those days - 41256s went from about $3.50 to $17.50 nearly overnight.
My main machine at the time was an Amiga 1000. I bought a 0K Spirit
Inboard inexpensively (for the day), then was faced with coming up
