Can confirm from experience that 16 MB is supported. However, even while shut down, a 16 MB RAM disk will deplete the main battery in less than 24 hours. So if one wants the Silicon disk to be persistent, one needs to leave the Outbound plugged in. I've toyed with the idea of building some...

Are you using the correct key sequence when you boot the Outbound? There's a different sequence for keyboard - docked, and keyboard - not docked, and if you use the docked when they keyboard is detached it usually won't work. Vice versa and one gets strange behavior, IIRC.

IIRC, various old Connor 2.5" IDE drives worked including 20, 40, 60 and I think 80 MB. You may have already discovered this, but you can switch between internal floppy and internal hard drive, by installing the desired hardware and then running the EEPROM updater (forget what Outbound called...

Vulnerable part of the display seems to be the flat flex cable that is so aggressively folded.

Bought one back in the 90s that someone had done that to. It killed a diode in the power supply. Machine would not boot up until I replaced that diode. Happily, Perfit was still operating at the time and they were willing to give me the part number for the dead diode.

Thank you.

I guess I should back up and ask, what, specifically, is a "gotek" drive? Is it different, somehow, from a standard PC floppy disk drive?

Thank you. So that's a proof that a standard PC floppy will work with the Outbound, as long as the Outbound Floppy Controller Board is present? Suggesting these Citizen W1D floppy drives should also work if connected?

Datasheet for the 85C80 is in this AMD Data Book, chapter 3. https://bitsavers.org/components/amd/_dataBooks/1992_AMD_Data_Communication_Products.pdf

Just to be clear, you connected the Outbound Floppy circuit board in between the Outbound and the gotek floppy drive?

Can you elaborate on this? Sources? Details?

CURIO is a physically separate chip from Grand Central. However, CURIO interfaces to the PCI bus through Grand Central. CURIO is a custom chip from AMD, designated AM79C950. Grand Central is a custom Apple chip marked 343S1125. CURIO contains a 53C94/96 SCSI cell, 85C30 SCC (serial)...

What's considered a reasonable price for 16 MB IIFX SIMMs these days?

Yep, as far as I can tell, the Beige G3 is the only machine that used this ROM module and ran on 3.3V. It used different pins on the DIMM to supply the 3.3V so installing a ROM DIMM in the wrong machine should just result in it not getting power at all, as opposed to damaging the DIMM's chips...

HY29F800 from Hynix or Hyundai also work. 90 ns or faster are needed. 70 ns is faster so they worked. I've seen 120 ns work, but I also saw some glitches, so I don't trust them. Memory Masters has a large supply. https://www.ebay.com/itm/175602575946?epid=1228687524 The 341-0757...

The through hole socket, which that design used, seems to be unavailable. I knew a source as of a couple of years ago and posted it in a Tinkerdifferent thread. Either the supplier got rid of them, or someone bought up all the stock after following my link. Similarly for the surface mount...

Might not help in Germany, but so folks don't need to "salvage" the 64 ROM socket: https://www.connectorpeople.com/Connector/TYCO-AMP-TE_CONNECTIVITY/8/822019-2

Heh. I tried to make an ANS to Mac CPU card adapter back around 2000 - 2001. Didn't work, but then my skills at the time were rudimentary. Might be worth another try. To begin with, it should be at least a 4-layer board. But back in 2000 4-layers at that size would have cost well over...

Are you sure that wasn't the memory for the PEx? I can't remember what we finally figured out it needed. I think it was 3.3V though... And if that's EDO then presumably it isn't SDRAM, which is what the Beige G3 needs. The only memory I have in large quantities is the 32 MB 72 pin sticks...

Thank you for pointing out that thread. I missed that one too.
