Designing a 9010 replacement LED display?
by John Robertson via Techtoolslist 09 Feb '24

09 Feb '24

I was looking at my 9005 and grumbling because the tube is missing, then I pulled out the 9010a service manual and you know, it looks like it would be a pretty easy fix to replace the tube with 32 digit alpha-numeric LEDs of the correct size on a small PCB and all that would be needed is to replace the UDN6118 fluorescent drivers with suitable LED drivers and find a place to grab 5V and ground and then mount the new display to the board... Maybe it would work? Anyone interested in poking at the KiCAD layout? I have no free time, but I know there are folks out there looking for a solution to bad or weak tubes...

Fluke 9010 ram test for 4 bits? Or any non 8 bit wide memory?
by davids＠oz.net 04 Dec '23

04 Dec '23

Have a suspect bad pallet ram on Missile Command, and I see that it is on the CPU memory map so I should be able to get to it from the fluke. Now it is only 4 bits wide (and only uses 8 addresses) so I can just do it manually but I have seen this on other boards before and never could find a way to use the fluke to test these 4 bit rams. Would also assume it could be a problem for 68000 based boards which use 16bit wide memory.

Data I/O Unisite - Issues
by Steve Larkins 24 Jul '23

Hey all I am hoping someone can help me with my Dat I/O Unisite. I have had this for a really long time but got it on the bench a month or so back to use it and it would not pass the self test. I ended up getting a fatal error reported on the com port via telnet and based on someone else's suggestion I tried replacing the floppy controller. This worked and got the system to the point where it reported a boot disk fail. I used a gotek with flash floppy and copied over a boot disk which then allowed me to get the system to boot but with a mass storage unit failure. I replace the original PCMCIA hard drive with a PCMCIA Flash adapter (Added a jumper to the adapter to allow it to work) and got it to pass a self test. I am now trying to transfer the system software via the \configure system\Mass Storage\Install new version of software and it fails at Algorithm set 3 disk. I have successfully transferred the 9.4 software disk, alg#1 disk, alg#2 disk but when it prompts me for alg#3 disk it tries to read from drive 0 rather than drive 1 like it did for the other alg disks. I have tried to switch disk 0 to alg#3 but it stops responding to the "enter" on the terminal and I have to press "^Z" to abort which it does. Even after this process off transferring the system software I cannot boot from the mass storage unit and it asks for a valid boot disk. Has the installation not completed caused this? Can anyone help?

Williams System 7 test ROM

I have an original Williams System 3-7 test rig, but I only have the original ROM image, that deals with System 3-6 (fits on a 2516). Can anyone point me at a copy of the later 2532 image that includes the System 7 tests?
