Re: help with unknown cards

The Echo II is a sound card, however it�s really meant for the IIe or II+. You
can get better sound out of the headphone jack than you can from this card.
If you aren�t interested in music then the Echo card has one possible
advantage,
it came with an external volume control knob on the speaker.
The RamPak 4GS was one of if not the earliest memory card made for the IIgs.
It was designed and made to the specs Apple gave to developers before the
computers release. The engineers at Orange Micro were understandably miffed
that on release the IIgs didn�t conform to those specs.( one I have was made a
month before the IIgs was released) The down side of this is the card has
problems with DMA so if you have a Hi-Speed SCSI card, DMA may have to
be turned off. Also like a number of other cards it doesn�t function correctly
with the ROM 3.
The card comes with 512k built in. It can be upgraded in multiples of 256k
(2 chips). The chips are 256 x 4, 150 ns or faster, CAS before RAS
A few examples of the chips #s are M514256A-10R, HY534256S-70,
KM44C256AP-10
Alllech has these chips.  phone 760-724-2404  They were at www.allelec.com,
however I haven�t been on that site in quite a long  while so I don�t know if
they list any Apple II stuff any more. Last catalogue I have had them for .75
each. However you need them in multiples of 2. I�d suggest bringing it up to
at least 2mb. More is always nicer.
