I've added emulation of most of the functionality of the 98550A 1280x1024 8bpp card. That makes now a nice virtual HP-UX for playing! :-) I'm now on the 4xx Systems - got a bootrom from someone which looks like a 400t Boot ROM - it expects a 68030. As you have a real 4xx, would it be possible to dump the boot rom + configuration eeprom? If you don't have the possibilities to dump it physically, it might be possible via /dev/mem in HP-UX, if someone on the list knows the details on how to use that special device. Best regards Sven

Yes, someone happened to have one on eBay: https://www.ebay.com/itm/302169367965 An Apollo keyboard and mouse also shouldn’t be hard to emulate with something like an Arduino and a PS/2 keyboard and mouse; the combination speaks a sensible and documented TTL serial protocol, and the 7-pin DIN connector can be obtained easily. The biggest difficulty would be mapping a PS/2 keyboard reasonably to all the special Apollo keys. — Chris

Re: HP-Apollo 9000/425t RAM
To follow up on this with what I’ve learned: As expected, lots of places online will say they have a thing on their web site, and then when you ask for a quote they won’t actually have it. However, ServerWorlds not only had HP 98229-66524 16MB memory modules listed, they also had a price and in-stock quantity listed! So I ordered a couple to try. https://www.serverworlds.com/hp-98229-66524-16mb-simm/ They have a whole lot fewer now, because it turns out that despite what it says in the HP-Apollo 9000/400 Series Owner’s Guide, the 425t *does* support 16MB modules! My system comes right up, all self tests pass and it says it has 32MB of memory with two modules. So I’ve ordered six more to get to 128MB. In the worst case, I figure it’ll only allow me to put half that in, and I can pass the memory along to someone else who buys a 9000/375, 380, or 400 series with no RAM. All that said I’m quite surprised MAME doesn’t include HP-Apollo 9000/400 series emulation. The hardware is very similar to the 9000/380, which is supported, and several Apollo DN series systems are also supported… Hopefully I can install Domain/OS on a virtual disk using MAME (using the same node ID) and just blast the raw bits to a SCSI disk to make something bootable. Anyone know whether that wouldn’t work? — Chris
HP-Apollo 9000/425t RAM
I’ve come into an HP-Apollo 9000/425t which uses memory boards with 72-pin headers rather than using SIMMs. Based on what I can see in pictures online, the boards themselves don’t appear to be anything special (they just carry TMS444000 etc. DRAM) and the connections aren’t anything special either, so I figure it shouldn’t be hard to design a SIMM adapter. Does anyone have or know where I could find the pinout and timings? -- Chris
