Quick question for those people with HP 1000 machines and the like... what are the front-panel keys like? Only I have a few discarded HP keys here that are all alike: Corbin Cabinet Lock CAT99 Corbin 4T1427 All the keys are brass. Are they for an HP front-panel lock of some sort? If so, which? -- John Honniball coredump(a)gifford.co.uk

Are these in electronic form? I'd like a copy. yep, see: http://home.iprimus.com.au/figjams/apple2/AP-64e.pdf Initial tests on the card seem to show it's working anyway.

I imagine the controller in the Apple needs to appear as a device on the SCSI bus; I believe that rules out some of the available cards at least. Plus the ID of either the Apple or PC controller would have to change from the default obviously - I think this can be done with all the Adaptec PC cards I have, not sure about the various Apple cards that are available. Would be an interesting experiment to try anyway. cheers Jules

That's true for a BA23 (3 slots plus 5), but in a BA123 it's four Q-CD, eight Q-Q, and the thirteenth slot is not bussed at all. > Older boxes can be wired for either 18-bit or 22-bit addressing, > which may or may not involve Q-CD slots. I _think_ the BA-11N is a > 18-bit Q-CD box... that's what I remember my 11/23 is in (but I > added the extra wires some time ago to make it Q22). Yes, a normal BA11-N is Q-CD. So is a BA11-S. If you can read the H92xx number off the backplane (it's often visible without too much effort, for example it's on the top of a BA11-M/N/S backplane) you can look that up to see if it's straight (Q-CD), serpentine (Q-Q) or mixed. The following is not exhaustive, but includes the common ones: PDP-11/03 BA11-M H9270 18-bit 4 x Q-Q PDP-11/23 BA11-N H9273 18-bit 9 x Q-CD H9275 22-bit 9 x Q-Q PDP-11/23+ BA11-S H9276 22-bit 9 x Q-CD microPDP-11 BA23 H9278 22-bit 3 x Q-CD, 5 x Q-Q H9281 18-bit various sizes, only two slots (AB) microPDP-11 BA123 54-17507 or 70-22019 22-bit 4 x Q-CD, 8 x Q-Q, 1 x non-bus DDV11 18-bit 9 x Q-Q, slots EF are separate Q-Q backplanes are usually referred to as serpentine (or sometimes as zig-zag), Q-CD as straight. Serpentine slot order goes like this: slot 1 ----> slot 2 | V slot 4 <---- slot 3 | V slot 5 ----> slot 6 etc Some of the backplanes have optional jumpers to enable/disable LTC interrupt, or for termination. Many carry the SRUN_L signal only on row 1. Beware of such differences when changing backplanes or linking two together. The DDV11 is unusual in being hex-height instead of quad-height; the extra slots are nor bussed, except for +5,V, 0V, and -12V, but may carry odd voltages, depending on which OEM or experimenter last used it! There's a rumour that the first 3/4 slots in a BA23/123 are special and you can't use them for anything except memory or processor; that's rubbish, they're normal Q22-CD slots and you can put anything that's Q-CD compatible in them, so long as it's after the processor. What *is* special is the range of PMI memory boards; if you put them in *front* of a KDJ11-B they use the CD interconnect for the Private Memory Interface but if you put them *after* the CPU they use the Q-Bus like all other memory boards. -- Pete Peter Turnbull Network Manager University of York

Vaxstation 2000 and VXT software, 4 plane color supported?

by sgust＠ithh.infoserv.de

Some time ago I got my hands on a Vaxstation 2000. I searched for some Information about the machine and read somewhere that it should be possible to run the VXT X terminal software on the VS 2000. The only version of the VXT software I found was in VMS BACKUP format which I could not read. So I put NetBSD on the machine, it runs disk-less from a PC with Linux. Last week I searched again and found version 2.1 of the VXT software in tar format, so I could finally try it. It works, but only in monochrome. If I put my VS40X 4 plane color option board into the machine it seems to crash when it has finished loading. Some pixels get randomly set and the machine does not react on the break switch at the back. Is the color board supported by the VXT software? Or is it a firmware issue? My board has version 1.4, are there newer versions available? Or even older version? Anybody want to swap firmware dumps? The loading process via mop often takes several retries or even fails completely, especially when loading the full VXT.SYS version. It seems to work better if there is some load on the Linux server, perhaps the mop daemon sends the data too fast. Has anybody else seen this effect? Is it possible to use the VXTLDR.SYS to load the rest of the software via TCP/IP? I know nearly nothing about DECNET and don't have any other DEC equipment to run it on. Another minor problem is that I don't have a real DEC mouse. I use a small Atmel AT90S2313 micro-controller as protocol converter. It currently only supports one mouse button and needs an Amiga mouse, but I plan to adapt it to PS/2 mice. The information about the DEC mouse protocol I found leaves some minor questions. How many packets per second does a real DEC mouse send in stream mode? I chose to send 60 per second, as this was easy to implement via the timer0 interrupt on the Atmel. What does a real DEC mouse return as revision and manufacturer code? I return 0 for both but fear that there may be some software which expects real data. Soeren Gust
