As this is right up their alley, you may want to post about this over on the SHMUPS hardware forum: https://shmups.system11.org/viewforum.php?f=6

Case closed, move on.

That full size crystal with the bent legs IS the original part shipped with the card. I was able to push my card to 12Mhz. Anything above that was a crap shoot, but I haven't upgraded the power supply yet.

6.25Mhz points to an earlier card I think. The GAL set installed is a good indication as well (more rev A parts = earlier card). A better date would be the ROM revision if you had the original 8k cache card. The 32k cache upgrade was offered separate and usually came with v1.8. What GALs is RE...

You should be able to lever is out slowly with a pick or hook style tool. At least that is what I did on my card, but I think mine has a more traditional style PLCC socket with slots on the sides for the extractor tools. I would be prepared to replace the whole socket though because the...

None of this is a surprise. Tons of "green screen" applications are in use today. I use a TN3270 session daily at work along with many other IBM CICS applications that were, ahem, "upgraded" to a web interface. A well designed 3270 or 5250 terminal application is WAY easier to work when than a...

Surprised Apple didn't have a Twinax solution as that was the most common way to connect 5250 terminals at the time. Today all this stuff is obsolete with the advent of TN5250 gateways so not surprised this stuff got tossed. The client performance quoted is pretty terrible. These are block...

I'll try to respond the best I can here and on the github issue request. To put it simply, I don't have an AsantéTalk bridge to do actual testing of the various Netatalk services. The only AppleTalk "bridge" solution I have ready access to is Apple's LocalTalk Bridge running on a Mac. The rest...

A lot of those Dell monitors have GENESIS "Display Perfection" video processors in them. Seems that supporting down to 15khz is an undocumented feature of them. Believe it or not, I have TVs that support 15khz, but only via the HDMI port. This is mostly only available when using something like...

AFP has a function called FPCopyFile that can duplicate a file 1:1... well at least it should. Its dependent on the server's file copy routines, which at least with Netatalk DOES produce an identical file. What I see here is a Finder bug..... and there are MANY. Not surprised there are bits of...

Does the drive work on a real Apple IIe 5.25" card or IIgs? I'd rule out if the drive is working first if you haven't tested it elsewhere.

The Apple IIe card only works with the later "Apple 5.25 Drive" (model #A9M0107). If you have the identical looking "Unidisk 5.25 Drive" (model #A9M0104), it will not work with the LC IIe card since the card doesn't output the required -12v on its 19pin connector.

Either do the above, or implement proxy ARP in macipgw like the hardware MacIP routers do.

These were so called "QuickDraw" printers. All the rendering was done on the machine itself and sent to the printer as a raster image. Generally no 3rd party drivers exist for these printers. The best printers to find are the ones that use Postscript and hopefully have Ethernet along with...

The ImageWriter doesn't reply back as a plaintext papstatus response. It outputs 2 bytes, and the various bits need to be decoded to get the current status. The current versions of papstatus now decode this, but the output might not be what this script is expecting. Sending PostScript to an...

Can you post the contents of the check-maciprpi.sh script? Its likely assuming the printer is a LaserWriter.

Quadras are going to get a bit of a boost in transfer speeds as they have newer SCSI chips along with SCSI Manager 4.3 drivers.

This isn't going to work with Ethernet. The IIe card software likely only has support for LocalTalk. AppleTalk is a two part system on the Apple II. One part of the stack is resident in ROM (or the IIe card software in this case) and supports all the lower level protocols, while the OS loads...

Its likely MAC locked, looking for the Apple OUI (MAC starts with 00:05:02 in the example above). Looking at OUI registration dates, it could also be 00:10:FA too.
