Hi all. Let me know if anyone out there has any info on this card. I got it in a box with multiple II+s, III, IIc+ ages ago. STB Systems Inc, 2283 with the number 1765 written down for S/N. 1982, Made in USA. I just hadn't found anything online.
STB = "Simply The Best". A clone manufacturer back in the day.
This card is a clone of the Saturn 128 card. It provides 128K of RAM. It can be used in Slot 0 of a ][+ to fill the function of a "langage card" but provide more RAM or it can be used in other slots. It is not compatible with //e "AUX" memory as it uses a different bank switching scheme. There is software that will allow it to be used to expand AppleSoft BASIC memory or to let it be used as a RAM disk. Some software like Locksmith and some other copy programs will also use this type of memory. I think there were also pre-boots and/or patches for programs like Visicalc and maybe even AppleWorks to use this kind of RAM.
Thanks so much!
Oh, I should mention that the docs and disks for the original Saturn card are on Asimov/Apple II Documentation Project. Not sure about this STB clone, but the original Saturn stuff probably mostly applies if it is like most other clones.
