...I think every piece of GVP hardware only accepts GVP SIMMS.
;-) One of my A500s is equipped with a GVP Impact! Series II SCSI controller / RAM expansion. It uses 30 pin SIMMs, up to a maximum of eight megabytes. I don’t recall seeing the GVP name on them. I would recommend trying whatever type of RAM that you can borrow, or purchase cheaply. A charity thrift store is good for such things.
