    PowerLogix UltraCache 1MB UC1MB

    It's the same IC on both sides. FYI, the images in that dropbox folder are the original 16MP that haven't been downsampled.

    @Trash80toHP_Mini thank you, barrel extension: It's still tricky because it's etched, not printed, and not very deep...

    I'll get a better shot of just that one.

    Here's side A: https://www.dropbox.com/sh/b0htt7cndolqywa/AACmfGGbtGxQ1gmJWpYiRLBXa?dl=0 Here's side B: https://www.dropbox.com/sh/lb9bheme7a0cns4/AAA-xySf03qlM7hie8N_hXjna?dl=0 I couldn't get the auto panorama to work on these... so hopefully you can glean something from them. if you need a better light on that center IC let me know.

    looks like that uploaded as a 0 byte file. Here's another. CY7C1345G-farnell.pdf

    Yes, I'll get some better, overhead shots with legible P/Ns

    Laterally speaking, my 4400 (granted a 603e) without the cache is painfully slow. With it, it's marginally chipper for its architecture, and that's only 256k. I think motorola made 512k and 1MB cache DIMMs for all the Starmax line, but good luck finding any of those in the wild.

    About lubricating that floppy drive...

    From what I've seen, application with something small, like a toothpick, is a bit more precise and controlled than a spray.

    I should also note that there's a Cache Profiler driver disk, which I will happily archive if it's not somewhere already. It's more than likely required to get those higher benchmarks, but I could be wrong.

    It is on both chips—sorry if the photos looked too identical or if I didn't call it out, but they were of each chip on the DIMM. So carefully remove the bridge there? Also, no need to try to bridge the pins to the surface connections? (please say 'no need' ) And yes, without the DIMM, the PowerWave works just fine without the DIMM installed. IIRC, the original 604/120 card was also set a 45 MHz bus. If you're interested, I don't have the means, but I'm happy to send the DIMM your way for analysis, trag.

    97 – 96 97) Chip enable: This active HIGH input is used to enable the device. 96) BW4# | BW4# controls DQ25-DQ32. Data I/O are high impedance if either of these inputs are LOW, conditioned by BWE# being LOW. not that I know what to do with that, but that's the connection.

    Here's the original press release dated June 1997: https://web.archive.org/web/19970627084117/http://www.powerlogix.com:80/news.html

    I would agree with you, and I wish I could find more corroborating information about the UltraCache, specifically, which I have yet to do, but I did find this for the RapidCache, which I'll assume is a predecessor to the UltraCache in terms of product timeline, but I did find this tidbit: https://web.archive.org/web/19980504163706/http://powerlogix.com/cachemarks.html At the very bottom is a MacBench score with a 225/45 MHz 604e, so one could assume (based on another assumption) that this product should work. I wish I could find information SPECIFICALLY about the UltraCache... I'll go search MacUser archives again.

    So, does anyone know if this was standard procedure? I think because it's identical it might be... but can anyone confirm by chance? I was looking at the cache dimm to see if there were any broken traces, etc, kind of a pipe dream now, perhaps...

    Centris 650 surprise

    I think RC was the full-featured version. LC lacked a coprocessor, and EC lacked n FPU and MMU.
