found the binder.. The HP 2600A is a Datapoint 3300. There was even a brochure from Datapoint in the binder along with an HP brochure. FWIW, the HP 2615A is a Beehive Mini-Bee (also in the same binder)

Datapoint 3300

by aek＠bitsavers.org

The service manual for the 3300 in on bitsavers under datapoint A line drawing of the case is on page 3-41 I have a brochure and the service manual for the HP 2600. From memory, it looks the same. Will dig it out and scan it.

Datapoint 3300 and DEC VT06 terminals

by swtpc6800＠comcast.net

I am doing a bit of research on Computer Terminal Corporation terminals and I am looking for a picture of the Datapoint 3300. I understand that CTC OEMed the terminal to many companies. I have found references to the VT06 being the same as the Datapoint 3300. I also found a HP document that list the HP 2600A as be compatible with the 3300. Can anyone clarify this. The designer of the SWTPC CT-1024 Terminal, Ed Colle, had worked at Datapoint on video terminals. My area of interest is SWTPC 6800 computers and they have an interesting connection with Datapoint. Both were located in San Antonio, Texas. When SWTPC selected a computer to run their business they selected a Datapoint 2200. They liked the way the machine booted up and did not require a front panel with switches. The SWTPC 6800 did not have front panel switches and lights. It booted up with a monitor ROM. I have some interesting notes from Gary Kay, the designer of the SWTPC 6800 here. (And a good photo of the Datapoint 2200) http://www.swtpc.com/mholley/History/SWTPC_History.htm Michael Holley

CP/M archive to image 8" CP/M floppies

by shoppa_classiccmp＠trailing-edge.com

I used to be more on top of CP/M archives on the net, but I haven't kept up in the past few years. I have images of several hundred 8" CP/M software, including original distribution disks and a lot of stuff pirated in the 70's/early 80's. I also have maybe 100 more 8" floppies with CP/M related stuff that ought to be archived. A decade or two ago I would image these other floppies myself but I'm no longer with the free time to do these activities. The floppies I have already imaged are available on the net at ftp://ftp.trailing-edge.com/pub/cpm/ Most of the images reside in cpm.zip, in a format where each physical sector is mapped to the image, resulting in a 256256 byte image. For the floppies that are in CP/M file format, there are "*.cpmdir" files that list the individual files on the disk. There are also "*.index" files that say what was on the floppy label. Are there any takers for the remaining 100+ CP/M floppies? Tim.

Actually saw one in use back around '81. It would be fun getting one of those going again, wrong coast though. If memory serves they (DCC) also did a 16bit machine cloned after a different platform.

looking for a book on monitor theory

by Watzman＠neo.rr.com

Re: > Purpose: the investigate the possibility of modifying > a recent multisync to sync down to TV frequencies. Eeek! ... Personally I think it would be easier to find an old TV-rate monitor and repair it, even if you have to wind replacement transformers yourself. But anyway..." This may not be all that hard. In fact, the early NEC "multisync" monitors DID this, as they came stock from the factory. CGA, MCGA, EGA and VGA. They even came with 9-pin to 15-pin adapters to deal with the two different connectors in use. I'm not sure that current monitors still do it in their "stock" configuration, BUT I WOULD NOT RULE OUT THE POSSIBILITY THAT SOME MIGHT.

Emulex SC02/C SMD Qbus controller

by hachti＠hachti.de

Hello folks, who has experience with the Emulex SC02/C controller? I tried the hardware format sequence - but it didn't work as expected. Perhaps my controller has a problem. Perhaps there is something set up wrong. And hardware formatting my disk packs is the way I hope to get these packs usable. In my documentation to the controller there's mentioned a diagnostic software - which I don't have. Does anybody have that? Best wishes, Philipp :-)

Could be wrong of course. Thats exactly what it is, a PDP-8e (work alike) clone. It's been a while since I'd seen one. A good washing and maybe new switches and I bet it's salvagable. Allison
