Interesting to see that result. Did you format the IDE drive HFS or HFS+? I also had mixed results formatting a CF-AztecMonster using many programs which worked great on hard drives. I know the SCSI bridge is likely to change the scenario, but in that case the most successful formatters were...

The bit about modifying the supply for PCI voltage is correct, but the 5300 is the final model before the switch to PCI. Yours should be perfectly compatible as far as I've heard. The 580/630/5200/6200/5300/6300(except the 6300/160MHz) are all share a board form factor and are equipped with an...

There's a Farallon 10BaseT card in the Comm Slot, Video-In/TVFM are both installed, and the hard drive is the (presumably factory) 516MB IDE which did accept the Disk Driver update during 8.1's preinstallation. Mac is running with 196MB RAM, but the DOS card still has only 8MB installed. At the...

I just re-tested this. • Fresh install of 8.1 on my 640CD (with a full 040) • Fresh install of PC Setup 1.6.4 and the PC can start • Upgrade to PC Setup 2.1.7f and the PC can still start Maybe it's the full 040? Edit: also, the boot drive is Mac OS Standard (for dual booting SSW7)

If the AppleTalk control panel is allowing you to select it and doesn't produce an error when you close it, the driver is probably correct. Did you also check that 'Alternate Ethernet' is selected in the TCP/IP control panel? (if that CP isn't present you should probably install OpenTransport as...

This kit would suit the original Orange386, which had two ISA slots (one 16-bit, one 8) and an additional socket for the disk controller (accessed via the octopus breakout cable.) I still have not found confirmation on what your model of card is called. It's 386-based (though some of the late...

I bought one of these in 2020 and I've been happy with it. https://www.amazon.com/gp/product/B07Z3PLKMJ/ The heat seems pretty consistent and it doesn't take long to reach operating temp. I haven't done very fancy things with it, but swapping capacitors, diodes, etc became much easier once I...

That's good news! Thanks for confirming

I remember reading a detailed swap attempt on hackaday a few years ago which ended with the assumption that something in ROM must be different. Maybe they just had two bad chips in a row, though the second seemed relatively thoroughly checked. https://hackaday.com/tag/powerbook-500/

I have a couple like this (but passthrough.) Mine are branded 'SCSI Rx' and 'AST-ST Plugged-In.' Typically yes, but I find them very useful to identify the normal probing patterns of a healthy SCSI chain and work out what's going wrong. When working with (basically undocumented) PDS SCSI cards...

I've had a couple of these displays on my bench for a few months now. I intend to perform more testing, but for now I've assembled a relatively comprehensive page of information here, so I can keep it organized as I update it: http://www.jeremywork.com/displays_ibm_bertha.html Hopefully this...

I've done some more guess-searching on this... The 8•24 has thicker traces for each of the color channels reaching the DA-15 plug. They're each routed behind L3 on the backside, and reach pins 27, 28, and 29 of the PLCC68. Pin 26 connects to the ground plane and Pin 20 connects through R22 on...

It did begin to make perfect sense that it'd be a Rev A, but I'm glad the ROM swap gave you something new! On the bright side, the 8•24 GC was optimized for 8-bit and Millions before Thousands existed, so even with 16-bit color is enabled it's usually not visually faster than 24-bit. Mostly a...

I already just realized I had it backward ;) Upgrading the ROM should add 832 x 624, but only the Rev B hardware gets 16-bit.

That brings up an interesting point though... I have an early example of a 4•8 (1986-90) and a later 8•24 (1986-91) which both use Bt 357S0010-A, same as mg.man's 8•24 GC. My GC however, has an AMD 343S1075, which probably is the hardware difference required to support 832 x 624. It still...

Except with 341-0266 I have all of the features indicated to be available only on Rev B ROMs and Rev B cards. 832 x 624 works fine, and 16-bit is enabled on both 832 x 624 and 640 x 480.

I don't know the answer to this, and the following might be of no help, but Dale Adams had a bit of information about the 8•24's chunky planar scheme which might at least narrow the search? [of the Quadra 700/900]

If memory serves, and you feel like spending the time to remove the little board from the case, you can also poke the broken piece through from the back. Could even glue the stub back onto the knob if it's still nearby.

This is what I've thought as well from my research. My card came with 16-bit working via its original 341-0266 ROM and even after PRAM reset, all I could get with 832 x 624 sense pins was a black screen when 341-0812 was inserted into the same card. Not even mono or 8-bit. I'm curious to know...

Thank you very much! My card happily runs from this ROM (the ROM I had, 341-0266, seems to occupy only the first half of the memory; it's attached below.) 341-0266 is listed as rev B in Apple's docs, but 341-0812 is not mentioned explicitly...
