@Hinoserm Possibly - I was talking to someone who had one. Sadly I think they need a later version of the ACC-4000 software than I have, but they seem to be fairly standard 68k processor boards with Ethernet and a decent amount of RAM, so perhaps something could be done with them. Whereabouts...

If you're using a 154x series, that's a Narrow SCSI controller, so it has no idea about that either. Wide SCSI devices will need to be put into narrow mode (if they support it) to work with a 1540. Because of the way SCSI addressing works, only Wide SCSI devices can have SCSI IDs above 7...

Quite possibly! I'm the same - the Adaptec PCI card in the cable headend has it, and I find it tricky to do without it. You can't beat the convenience of firing it up from ROM without even needing a bootdisk. My AVA-2906 PCI doesn't have it (no boot ROM), and my AHA-1540B ISA card has a boot...

Acorn Fileservers use a hidden vendor-specific modepage containing the text "(C)ACORN" - I expect Apple may have done similar. That sounds like Adaptec's SCSISelect, which is in ROM on the 2940 PCI controller. It's used to configure the controller but can also do some basic diagnostics (device...

Glad you're enjoying yourself! It seems like people are having a good time - I have a couple of friends out there who have been sending photos. I wish I was out there, it looks like a good time! I'll be looking out for the panel recordings when they land on Youtube. That Stylistic tablet is...

I'm not sure I'd recommend that, given @amichlin's experience and my own. Hopefully someone can get through to him. I've had the same experience, sadly. I've no involvement but tried to suggest to Jason in a semi-private venue (Discord) that it might be an idea to step back and take stock...

I've done some more digging ... There's an ACC-4000 manual on Sega Retro which lists several newer models: ACC-4000/PL Model 5500 - a Compaq Proliant 5500. ACC-4000/PL Model 800 - a Compaq Proliant 800 ACC-4000/HX Model 6200 - Digital Prioris HX 6200 Here are some hints for identifying an...

Good news! I got the ANIC working. It turned out to be battery leakage - there's a buffer chip next to the CMOS battery. When the battery leaked, it took out four tracks under the chip ... the buffer was for the RAM address pins. I fixed the tracks and put it back in the PC I built to run the...

I'd ditch the ATX power supply and switch to a lab power supply, if you have one. Disconnect all the boards and accessories from power and start with just the main processor board. If there are any parts which require multiple power rails and might get upset (old DRAMs like 4116es) - remove...

Those are some nice die shots! The AMX14 looks like some kind of test device. There are some tracks going from bond pads on one side of the chip to the other, which I guess would be useful for measuring metal layer resistance. That said, it looks like the silicon is doped underneath - so they...

It looks like you have the Microvitec variant which was intended for use with their Apple II video card. The colour palette you have looks very similar to the colours that can produce. See this post: https://stardot.org.uk/forums/viewtopic.php?p=412755 For CGA you need to program a different...

What an odd thing! Had a dig around and found some old posts on classiccmp about it. Apparently under one of those labels is the text "Corollary Inc". Digging for more on them turned up a few things: https://www.1000bit.it/ad/bro/brochures.asp?id=631...

Digging deeper, I found a Year 2000 declaration which identifies it. It seems like it's an early ACC-4000 (called an ACC-4000/XP): http://web.archive.org/web/20010108065700/http://gicout60.gic.gi.com/year2k/html/product_compliance/ANS_plans.htm By the software notes, it could have been updated...

I was never expecting to see that ...! I think you have one of the ACC access controllers - an early one. Possibly an ACC-2000 or 3000, but it's hard to tell without booting it up (and knowing the passwords) The ANIC is an "Asynchronous Network Interface Controller". It connects the PC to the...

I've spoken to the seller - they're unwilling to move on price. I asked about getting a Xerox of the manual and they asked for $400. I'm not surprised the ACC stuff was recycled years ago. I'm really just hoping someone has a software disk lying around somewhere. I found a photo of what looks...
