http://www.ebay.com/itm/111013285214?ssPageName=STRK:MEWAX:IT&_trksid=p3984… There's already ample bids on it, so I guess I shouldn't feel that bad. The first time I've ever *seen* one. Heard about it all the time back in the day. Looks like the old C64 case. Being a Commie expansion option makes it more collectible in my eyes then the fact that it runs the other s/w. Would be nice to have one. Sure would be nice. Probably not this week.

online cross ref hosting found, still need a few other things

by sales＠elecplus.com

A volunteer has come up for the hosting space and software (all open source, Linux) I have the data, and will put it into uploadable formats, and provide templates for others who want to contribute also. I am NOT a php programmer, so a volunteer is needed who will design the site and create a script to do the searches and display the results. Any volunteers? _____ No virus found in this message.

QX-10 / terminal software

by jules.richardson99＠gmail.com

Morning all, I thought I'd try and get the ol' Epson QX-10 running as a dumb terminal. AFAIK, there's nothing on the 'standard' set of disks to do this (e.g. valdocs has the 'mail' program which is aware of the serial port and which I think can talk via a direct link rather than a modem - but I think its functionality is all quite high-level and there's no 'terminal' mode). So... MEX looks like a possibility, and an overlay for the QX-10 seems to be available (although I'm not sure how much work is involved in merging them yet). Does anyone know of any other options[1] which will work with the QX-10's serial hardware? Or, does anyone happen to have a QX-10 enabled version of MEX archived already? [1] does CP/M abstract serial hardware into a set of common calls, or is that outside its scope? cheers Jules

I have an HP 7975A (TU20) tape deck manual on the way. I will scan it and send it to Al. I have not been able to find any documentation on the rack of electronics in the bottom of the TU20 cabinet. We don't have the I/O cables to connect the TC59 to the PDP-9. We have some spare generic B, R, and S modules. We probably don't have any spares for the special modules for the PDP-9 and TC59.

Need Kermit for Xerox 820-II in .IMD format

by xmechanic＠landcomp.net

(Think I may have goofed on my earlier post (excess formatting)) Hiya, Just wondering if anyone has a Xerox 820-II with CP/M 2.2C that already has Kermit installed, that could make a Image Disk of it and upload it someplace? I have Dave Dunfield's Image Disk program, and I've successfully transferred several programs to the machine this way, but I'd like to have a comm program to transfer stuff, as I'm using a modified cable from the existing 8" floppy drive to an old win98/DOS PC for transfers, and I don't like to disconnect and connect those 50 pin edge connectors on and off the boards too many times. I actually have the .HEX files for the machine, but I tried to get them transferred with 22disk, and it doesn't seem to like 8" drives too much (ver. 1.42 or 1.44). I also tried the host terminal transfer, but hex files seem to wreak havoc and don't transfer properly. So I'm kind of stuck between a rock and a hard place. If anyone can help out, it would be greatly appreciated! Thanks. Dave Land Land Computer Service

online cross reference?

by sales＠elecplus.com

Is anyone interested in hosting an online cross reference for components both small and major? I have a fairly large (3000+ line items) of cross reference for hard drives, CDROM, CDRW, NIC cards, video cards, etc for computers and servers that I would be willing to contribute in spreadsheet format. Also MANY hard copy sheets of old printouts for parts that go into HP and IBM servers. Cindy Croxton _____ No virus found in this message.

DG Nova repair etc.

by RolexTM＠gmx.de

Hi all, Tony, thanks for your input, we will check the PSU on Thursday when we get to the machine again. as Christian pointed out, the problem is not so much the pure amount of components but the puzzle game of identifying them since they have been relabled. Whats definitely worse when comparing to out old VT100 is that the DEC manual has one complete definitive service manual that covers all schemes and logic. For our NOVA i failed to find a comparable thing. I have constantly to go back an forward through all kinds of docs. Again I may be unable to find a "real" service manual, if you know any let me know ;) Bruce, I am looking forward hearing from you. It would be great if you come up with anything helpful before Thursday so we can check everything out. Dwight, we are currently missing the exact schematics for our machine. I hope thats where Bruce comes into play. The only real schematics i found were for the NOVA 2, and a quick glimpse showed that the machine is different (at least the layout of parts). None the less we will keep our eye on the clock(s), i guess it will do no harm and make our scopes and logic analyzers happy ;)

networking via SCSI

The machines are configured as multiple initiators and can send storage requests over the SCSI bus to shared disks or arrays. You still have to have another connection (usually Ethernet) for machine->machine cluster communication. While I haven't looked into it much beyond pinouts, DEC produced the proprietary DSSI which, in some cases, used SCSI ASICs - indicating that at some level it was similar (HSD-05 used, I think, an Emulex at either side. Can't check now, but can later). The protocol was different, and cluster communications could go over the DSSI bus between machines. I'm not sure whether the lack of a similar setup for SCSI is more because of impossibility or because Fast/Gig Ethernet came about and there was no longer much of a reason to not use the Ethernet for cluster comms.
