Thread: WTB: Intel or IDT TurboCache 485

  1. #1

    Default WTB: Intel or IDT TurboCache 485

    I am looking for this rather obscure external L2 cache module. This board was manufactured by Intel and IDT and used over about a two year period on a variety of 486 systems using a 33Mhz bus in the early nineties. Machines that I know of using this item:

    Multibest Industrial MB4861DX
    Epson ExpressStation 486
    Packard Bell 22/23 motherboard
    NCR 3350 and 3434
    Reply 80 Planar
    Intel L486
    DECpc 433
    Morse Technologies KP 486EDX
    Zenith ZDS
    Zeos 486/33
    IThe board contains a total of 4 rows of 28 pins and looks like this:



    There are 64K and 128K versions and here are some of the part numbers:
    IDT7MB6091
    IDT7MB6098
    IDT7MB6098SA33K
    I82485MA-33 (64K)
    I82485MB-33 (128K)

    I would be happy to pay a reasonable amount for this card to finish off my project:

    NCR System 3300 Model 3350 Microchannel Desktop

    486DX2 upgraded to Pentium 83Mhz (POP5V83)
    16MB upgraded to 192MB RAM
    Windows 95 upgraded to Windows NT 4.0 Server (looking for MP-RAS)
    Conner 540S upgraded to Quantum SE 2.1 SCSI Hard Drive
    3Com529TP Ethernet

    Also, I have a complete Apple IIGS system (but w/o any fancy network, storage or accelerator cards) with drives, RGB monitor and dot matrix printer free to a good home (I need to have shipping & handling costs covered that I estimate to be around $40). Every thing works fine except the printer that needs a cartridge. Plus a bunch of games and school software. Hurry before I get around to listing it on eBay!

    Send me a reply for more details if needed.
    I have a case of sealed modules. It's the same carrier as shown in your
    photos. This version has the 80485 cache controller and micron cache
    chips.
