I think we should keep E&S systems apart from DEC systems. They are not the same, and mixing them up just confuses the issue. The system in the video was not something by DEC. However, DEC had bitmapped graphic systems long before this, but not with the resolution and depths shown in the video. > The PS/390 was the first "Picture System" to support raster > operations.

Well, the E&S PS/340 also was a raster display system, as an add-on to the PS/330. See http://www.bmsc.washington.edu/people/merritt/graphics/ps330/ps330.html I think it might very well be that which is shown on the video. Raster operations are another issue. The video is showing a bitmapped high resolution picture, and it obviously isn't too fast at loading another high res picture. And that is all we see them doing. No raster operations of any kind (unless you count the basic setting and clearing of pixels). > Similar technology to that used in the PS/390 was used in E&S's first > workstation the ESV.

Wanted: RS/6000, 5250 Twinax cable/terminator, AlphaServer 1000A SCSI cable/terminator, DEC 3000 motherboard

by andreww591＠gmail.com

I am looking for a few things: I recently picked up an iSeries 270 and an AS/400 Model 200. A terminal and an 8-port Twinax hub were included, but not the cable to connect the terminal to the hub. The terminal has a "Y" cable with a DA15 and two female Twinax connectors. The connectors on the hub are also female, so I think that what I need is an M-M Twinax cable. I'm not sure if a terminator is required for the un-connected Twinax connector on the "Y" cable or not (I'm not really very familiar with AS/400s). I have an AlphaServer 1000A 4/266 which is missing the terminator for the internal SCSI backplane (because this is missing, the SCSI drives sometimes stop responding and cause the system to hang). It is also missing the cable to connect the two sections of the backplane. Does anybody have either of these? I have a DEC 3000/300X that no longer boots. The diagnostic LEDs show "FA", which represents a memory test failure. I think that one of the SIMM slots is damaged. When I got it, it would only boot after I removed and re-installed the SIMMs. I tried cleaning the SIMMs and slots with 99% alcohol, so I don't think that dirty contacts are a problem. I think that replacing the motherboard would fix the problem. I am also looking for an RS/6000 (preferably one with PCI rather than MCA). Does anybody have one that they want to get rid of for free or cheap?

Dear Madam/Sir, My name is Thomas Bervenmark and I work at XaarJet AB in Stockholm, Sweden.

DEC H777 PSU

by binarydinosaurs＠gmail.com

Folks, Got a PDP 11/04 on the bench here at work with an H777 (54-11599) PSU in with a sticker on it that says 'pop, bang & smoke'. I've downloaded the maintenance printset from Manx (yay Manx) but before I even begin I've noticed a terminal block on the transformer that indicates a jumper between terminals 1&2 and 3&4 for 115V and an additional jumper between 2&3 for 230V. This third jumper is missing so have the owners of this PDP just put 230V across a PSU jumpered for 115V? Thanks! -- Adrian www.binarydinosaurs.co.uk

Nice information, thanks. After searching the net for a while, I think it is an E&S graphic system. ES340 seems most likely, but ES390 might also be it. There are information about an older system for the PDP-11 machines by E&S on the net, which strikes me as very similar, and probably a kind of predecessor. Johnny

VAX graphics

by pontus＠Update.UU.SE

Hi All. I just stumbled upon this video of a computer tablet: http://www.youtube.com/watch?v=aPC_w9yYe5M They show a VAX-11/780 with RP06 and TU70 (I think) and claim its doing the graphics. But I'm curious, what terminal and software is used? Does anyone have a clue? Regards, Pontus.

FC5025 USB 5.25 floppy controller - first report

by jack.rubin＠ameritech.net

I ordered my board as soon as I got the announcement on Thursday. I received the board today (Saturday) and took it for a spin - imaged an Apple 16-sector disk and an MSDOS 1.2M disk using a YD-380 as the source drive. Both worked great - the Apple disk produced a .dsk file that opened and read in CiderPress and the DOS disk produced a .img file that looked good in WinImage. I was tempted to hook it up to an 8" drive using my DBIT adapter but hesitated based on the discussions here. Would the DBIT adapter provide the necessary buffering to drive a Shugart 801? I really like the idea of an 8" drive connected to a netbook. Jack

BNC to VGA Cable

by emu＠e-bbes.com

Hi all, a source for a BNC to VGA cable ? (Yes, I have a soldering iron, but like to buy some ;-)) The other way around (VGA->BNC) is easy to get, but don't find any BNC->VGA(15 pin) Cheers & thanks

forget it - DEC H777 PSU

DWQVA?

by mark.kahrs＠gmail.com

Curiosity demands that I ask about the DWQVA. The module catalog(ue) lists it as "2 channel fiber optic interface (IFQ), Qbus to Stealth bus". What IS the stealth bus? No, I am not going to buy any of the ones on epay.
