Epson QX-10 Q10CMS board

by jules.richardson99＠gmail.com

Hi all, There was a post in one of the Facebook vintage groups from someone who has Epson QX-10 Q10CMS and Q10GMS boards. The GMS is what I have in my own QX-10, but does anyone know what the CMS board is? Both boards have a NEC 7220 graphics controller, but the CMS appears to have more on-board memory (384KB vs. 256KB). On the other hand, I'm not seeing any on-board ROM in the photo of the CMS, unlike on my GMS. cheers, Jules

by me＠larbob.org

Does anyone have a copy of Compaq C V6.5-303 for Tru64? It used to be available from https://h20392.www2.hp.com/portal/swdepot/try.do?productNumber=T64_DTK, but this link has been dead for a while and hasn't been archived.

ISO: DW8E parts

by derschjo＠gmail.com

Hi all -- I picked up a DW8E backplane from a friendly listmember this week and now I just need to find parts to populate it (a simple task, right?); I'm hoping to use it with my negibus PDP-8/I for my ongoing TSS/8 project(*) (in order to provide numerous serial lines and if I get really ambitious/lucky, an RK05). It looks like I need an M7101 and four M7103's. I intend to build the cabling myself unless anyone has a set of single-to-Y (BC08D) I/O cabling. Also on the hunt for a chassis to put these in; this is identical to the one used for the PDP-8f/m (but sans blinkenlights). Thanks! - Josh (*) RF08 restoration is underway and emulation of multiple RS08s is in progress...

BA11 power filter

by steve＠cosam.org

After a few years in storage I'm finally getting to play with my PDP-11 stuff again. Figured I'd start small so rolled out the 11/23. PSU looks fine, pulled all the cards and checked voltages, no problem. Shortly after however, some magic smoke was released from the block in the back where AC comes in and the power switch is mounted. The only other thing in there is a big old line filter. Judging by the smell, I suspect a filter capacitor has given up the ghost. I'd check, but the whole thing is soldered shut so not exactly easily serviceable. Would I be correct in thinking such filters aren't entirely necessary and could just be bypassed? It looks like the manufacturer (JMK) is still going so a new replacement might not be out of the question. Whether I could find one with the same mounting holes etc. is another question I've not looked into yet. Cheers, Steve

VAXstation 4000/vlc mouse issue

by healyzh＠avanthar.com

I now have my VAXstation 4000/vlc up and running OpenVMS 7.3, DECnet Phase IV, and part of my cluster. It?s using a SCSI2SD v5.2 board for the hard drive. While have plenty of DEC Hard Drives, I like the lower noise, power, and heat of the SCSI2SD?s, plus I can really cram the disk space in there, this has a whopping 32GB. :-) I?m using a VSXXX-AA mouse (Hocky Puck), and when I use the middle-button on the mouse, it messes up DECwindows, and I?m no longer able to use the other buttons, which means I can?t change to another window, or access menus. It remains like this until I either logout, or reboot. Does this sound familiar to anyone? This is actually the first time I?ve used a VAXstation as a VAXstation, so I don?t know if this is normal (though I can?t imagine it is). Zane
