I've seen the ads for the 1500 and 1525 when the ZipGS was just being
introduced. I may be wrong but I was under the impression that Zip had
decided not to market those and that they were never actually sold.
Anyone ever seen any for sale in a store or seen one in person?
Still, it's a good that they had Zipchip type accelerators for the IIgs
developed. Wish they'd made something upgradeable like the ZipGS
for the IIe
