Maybe you can find someone in your area with an HP/Agilent logic analyzer that you can borrow. There is an 6800 Inverse Assembler than can run on an HP/Agilent logic analyzer that can be set up to work with a simple DIP test clip connection to 6800 CPU. The CPU address, data, and control signals...

Thanks for the update that you were able to get those diag images to work for you. The funny thing about you needing to convert the .DSK files from logical to physical format is that my work flow here must have been to first create the ImageDisk .IMD disk images by reading the physical floppy...

Looks like I never uploaded those disk images here. The file attachment size is larger now that it was 6 years ago. Those disk image are now attached here. MICRO-11_Cust_Diag_V18.zip contents: CZFNAP0.DSK CZFNAP0.IMD CZFNAP0.TXT CZUF1S0.DSK CZUF1S0.IMD CZUF1S0.TXT CZUF2T0.DSK CZUF2T0.IMD...

Oh yeah, I forgot what might be the most common reason why some PCMCIA linear flash cards might not be recognized on a Linux system and not do anything when you insert them. Plug and Play for PCMCIA cards normally relies on the cards having a valid CIS (Card Information Structure), which...

What is the AMT service / driver? I'm not familiar with that. Two years ago I spent some time looking into reading and writing PCMCIA linear flash cards on a Ubuntu Linux system. I was eventually able to get things set up and working with a desktop system with PCI add-in card CardBus...

Sounds like you want utilities that your can run from a system booted into DOS. If you're also open to running SCSI utilities on a Windows or Linux system, I've found the sg3_utils package to be helpful. https://sg.danny.cz/sg/sg3_utils.html There are basic info commands such as sg_inq and...

Do you mean the module expansion adapter, or the SBX-251 bubble memory module? The module expansion adapter doesn't look like it is too complicated. Two 8259A interrupt controllers and 18 common 74LS TTL parts, and a few passives. Maybe the more difficult part would be the getting an accurate...

I took a look at the iPDS units I have. Only one of them has the second 8085 processor board and the SBX-251 bubble memory module installed. None of the others units have any expansion boards installed. If I'm going to bother keeping any of them, the one with the expansion boards is the one I...

Anyone not too far from the Seattle area interested in a 2 drawer, 4 processor AlphaServer ES47 system? Due to the size and weight of these this would be local pickup only. The two system drawers are meant to be rack mounted. They are approximately 18 inches wide x 7 inches tall x 36 inches...

I don't think I have every heard of Eon Silicon Solution, Inc., previously. If that flash chip is actually a EN29F010 with a customer part number printed on it, according to the datasheet it should have a MANUFACTURER ID of 1Ch and a DEVICE ID of 20h. JEDEC PUBLICATION Standard Manufacturer’s...

Most likely it is a 128Kx8 flash chip. If you just want to read it, you could try selecting something like a 29F010, 29C010, 28F010, or 28EE011 device. If you try that and the programmer reports incorrect vendor and devices IDs when you try to read the device, what values does it report for the...

All your PAKs are belong to us. For sure, for hobby use on VAX or Alpha, at this point just gen your own. (IANAL, this is not legal advice :))

The main reason why I shared that particular Figure 8-19 from the EK-PDP94-MG-001 PDP-11/94-E System User and Maintenance Guide is that it shows the H9277-B 54-17228-01 9-slot backplane with the 5 ribbon cable connectors J1, J2, J3, J5, J6 to contrast it with the 9-slot backplane photos in that...
