Per hardware developer notes, Catalyst, TNT, Tsunami etc. only support 5v EDO or FPM. 3.3v has a different keying - it will not physically fit in a 5v socket. The Tanzania (Motorola Starmax or Apple 4400) are the only 3.3v EDO compatible machines afaik.

I bought a 20“ and will pick it up in the coming week. Then it is surgery time 😜

I recently got two acrylic ADC 20“ cinema displays. One is discolored but more or less ok - albeit dim. The other one still works but shows the short-short-long error code (backlight issue). Changing the backlight was described here...

- Only 3.3V EDO will work (5400, 5500 and 6400, 6500 use 5v FPM or EDO) - right, not easy as most ebay listings for 4400 or Motorola StarMax and other Tanzania Clones unfortunately show only 16 or 32mb

If i remember correctly, one of Radius‘ first products was a 16Mhz 68000 accelerator.

I count 24 NEC D41264C 4bit x 64k dual ported VRam chips - 768kb VRam. I guess that‘s not enough for 24bit even at 640x480, you need 921kb or simply 1mb.

Radius Precision color 8 is an accelerated 8bit card and it is not part of the above mentioned benchmark overview.

… and it still pops up at ebay for 1199 € with one CPU…. https://www.ebay.de/itm/374150035863?mkcid=16&mkevt=1&mkrid=707-127634-2357-0&ssspo=StEgxQSlRDG&sssrc=4429486&ssuid=9zjK9FpxTJ-&var=&widget_ver=artemis&media=COPY

It‘s a Sawtooth 450 Mhz. I can also testdrive the card in a G3 Minitower 266 and a 1.25 Ghz dual MDD. Is the PCI Bus driven by the Uni-North IC even without any other PCI card so limited on early G4s? edit: did a retest in the G4 MDD - it is almost reaching 100mb/sec. Thus no real benefit for...

Indeed. Got one today, flashed it and just lifted VCC. Works seamlessly under OS X 10.4.11 and OS 9.2.2. however when i benchmarked an attached Samsung EVO 840 and a cheap Alibaba Sata SSD, the transfer speeds are limited to something like 70mb/sec. Changed from a yellow to a black Sata cable...

See the Motorola Yellowknife L2 schematics…. https://www.nxp.com/docs/en/reference-manual/YKNIFEX4HW.pdf or IBM‘s long trail here: https://www.applefritter.com/files/lt_tour.pdf 160pin Cache on a Stick (Coast) module - more in line with the PCI powermacs……

Back in those prep/chrp days, gossamer and other mainboards like yellowknife or long trail etc. were designed with both 604e and 750 in mind. RS/6000 had 601 and 604 and some RS/6000 were based on CHRP. Thus, a L2 cache would be beneficial for 604e based boards. I worked with a Tatung 6000...

Pinnacle Video Capture for Mac. It has composite inputs and a USB 1.1 or 2.0 compatible interface. https://lowendmac.com/zisman/09az/pinnacle-video-mac.html

Then I guess, the GA21 that I have supports 1152x870 with 24bit as the 21 obviously stands for 21“. In those non-multisync days, 640x480 was assigned to 13/14“, 832x624 to 16“, 1024x768 to 19“ and 1152x870 to 21“

The Formac PCI cards may have the same designer as the older Nubus Versions. Other than that, not much info to be found elsewhere.

Have the same card in a Mac Iix. Wonder what features it has. The Web is quite silent about those german brands....

I went out to grab an old Mac Iix from a garage sale last weekend and when I opened it, it was full of surprises.... dusty but with no visible issues except of the rusted shielding on the bottom of the case (have to examine closer) a nice amount of 20mb Ram huge old style Network card with AUI...

I just received some old Macs with rather unknown cards (to me at least). One is a Modam Mac II Interface - a 12" Nubus graphics card with DB9 video port. It has 4 NEC dual port VRam chips 41264-120 64kx4bit. That is the same IC used on the Apple High Resolution Display Video card. I have once...

I do remember (now almost 28 years ago) that when visiting the Apple certification labs, the reps then said that we‘re free to select any supported CPU. Tanzania (or morroco as Moto called it) was indeed designed to be much more open and also more appealing ( PCI graphics, 5 PCI Slots). Apart...

Indeed. All three need an extension to enable the back-side cache lf the G3/G4. Only Alchemy and Gazelle need another Init to switch over from 603e to G3/G4. Running the patched MacOS X Beta on Tanzania with an installed G3 card worked after some fiddling and the cache could be initialized...
