OctoRAM Card Information Needed

[Bryan Villados <news001@macgeek.org>]

Hi, guys!!!!

I'm just now installing an MDIeas OctoRAM card with an OctoRAM ESP card.

One difficulty I'm running into is upgrading the RAM on the OctoRAM
card. I've installed eight 1MB 30-pin SIMMs (80ns each). The first bank
and second bank are different makes, but they're both running at the
same speed. When I boot my GS up, it only recognizes 4MB. I notice that
there's a block of jumpers on the ram card, but I don't have the
manuals for it. Is there some kind of jumper setting I need to set to
have it recognize all 8MB?

Another problem I'm running into is the ESP card. It's functioning
fine. However, when I copied the PRODOS file and the SYSTEM folder from
the install floppy to the ROM disk (it has Apple II Desktop on it), set
the control panel to boot from ROM disk, then boot from it, the system
crashes when it attempts to load ProDOS-16. I booted from my hard disk
running GS/OS 6.0.1, then attempted to drag the contents of the ROM
disk to the trashcan. When I tried to empty the trashcan, it gave me an
error message saying the disk is damaged (it's still enabled for
read/write). Are there any utilities I could use to test the ROM disk
integrity? I'm wondering if one or more of the static RAM chips on the
ESP card is damaged. It requires low profile 32KB x 8 static RAM
running at 120ns or faster. So if anyone knows where I can buy this
kind of RAM, please let me know! :)

Mahalo, guys!!!
