greetings.
I need some help getting the documentation for a card.
I have gotten some "disk emulator" cards, based on EPROM/FLASH/SRAM/NVRAM, bassically an early "SSD"
From the Promdisk IV (I got one) I have been able to find some documentation and software. but for the PCD-890 (I got 2 of this) only some software.
I haven't tried the cards yet, but I read the chips both had in it. They contain MS-DOS 5.0 and some industrial software.
With the soft and documentation of the PROMDISK IV I will be able to use it (it is a somewhat newer card, it seems), for that I am accumulating flash chips (I don't have an ultraviolet eraser).
But I would like to be able to do the same with the larger cards, because the total larger capacity you can get (12 MB vs 4 MB the smaller card)
I would appreciate if anyone has documentation for the PCD-890 card to share it. I am attaching the only thing I have found about, basically just one specifications sheet.
And pics of both cards
