[comp.sys.cbm] maverick v5

grx0644@uoft02.utoledo.edu (03/16/91)

Hello!

	I just got my copy of maverick v5 from tenex and the manuel talks about
an 8k drive ram. My question:

1) how much ram is in a standard 1571?
2) can I upgrade my 1571's ram without paying the 49 bucks?? Any ideas what
   chip I need to purchase, estimated cost of the chip,special instructions?

Any other constructive info is welcomed!

A standard 1571 (or 1541) has 2K of RAM, which is insufficient to store
an entire track of data.  Thus, to copy entire tracks at a time, more
memory (8K) is needed.

Sure, you *could* do it yourself, but only if you are an electronic
wizard.  The 1541/71 was not designed to have any memory added to it, so
it is not a simple matter of adding chips.  RAM address decoding logic
must be added, in a way that does not interfere with the internals of
the drive.

When you get down to it, $50 is pretty cheap for what you get.  However,
you might want to also get the Speed Control Box from SSI if you're
planning to do serious disk duplicating.  Many protection schemes
require you to slow down the speed of your drive, a very tedious
process without the Box.
