Just on the off-chance... does anyone have schematics for the Perq 1 portrait monitor? Mine is sick... and there are none on bitsavers. On first power-up there was a faint raster pattern but that quickly vanished and now there's no sign of life from the tube heaters...

I know the square root of bugger all about Altairs; I'm mostly a DEC pdp and IBM mainframe/midrange guy. I picked up the Altair a few years ago as an 'oh by the way' thing when I saw it at a cheap price; I'm only just getting into it now. It does basically work; it seems to be running some kind of ROM because when I power it up it runs and the lights chase like a register increment thing. But can't do much else due to broken/flaky switches. I'll pick up some Altair schematics and see what's called for in each switch position.

So you reckon those 7105SY9V3BE would suit the Altair? OK I'll go shopping. I've had a wee Google for Altair pics and mine seems to be an oddball. Most of the pics I've seen have all the switches the small type with rounded 'baseball bat' ends. A couple had all the switches the larger type with rectangular 'cricket bat' ends. Mine is the only one I've ever seen with a mixture; small switches for address and data - large for the control switches.

I wonder if Guy has had any time to work on his. A plug-compatible Massbus disk/tape emulator would be a Good Thing; there are things like pdp-10s that rely exclusively on Massbus and rare finicky power-hungry beasts like RP06. I kinda heard that LCM were working on something like that but don't know how far they got. Setasi had a disk emulator system based on a PC with a Massbus-on-FPGA card but they're rare and pretty unmaintainable too; I have one but not got it working yet. IBM channel-attached DASD would be another good one. It exists - the FlexCub. I know LCM use those too - but the price is commercial and way way up there. A hobbyist license for that would be helpful! I have a System/3 pretty much ready to boot - but it never will unless I can find or emulate the 3340 disks which are the only things it can use.

OK I still can't get at the box; it's apparently buried deep. So can't confirm what the label calls it.

On the XVM systems I have the paper tape function is integrated in the BA15 Peripheral Expander (a small collection of boards which lives at the bottom of the CPU rack) and which doesn't have any indicator panel. I'm not aware of any memory indicator panels associated with any pdp-15 configuration but I could be wrong!

Negative - I think. The PR68 was a small orange paper tape reader AFAIK; Robert Krten has one: http://krten.com/~rk/projects/pr68.html I have one of those too!

Have a look at http://www.corestore.org/pdp.htm It's very badly in need of a refresh and update but you might find some stuff there... especially the unique style of panel applied to the later (XVM) pdp-15s. I also have an odd box... it's pdp-8/L in style but housed several sets of boards for controlling multiple paper tape readers/punches IIRC... can't recall the DEC designator. It has an indicator panel built in to the front of the box rather than mounted at the top of the rack.

If you opened up one of the modules it would look like this... bunch of ECL chips with copper heatsinks conducting heat to the outer alloy casing where the water cooling manifolds would be bolted on. And all that internal cavity with chips and heatsinks was filled with a... sticky goopy fluid to aid in heat conduction.

Someone provided me with a hex dump of memory starting at location 80 as you say and what I found was that the code I was seeing that the UC17 had loaded into memory had several locations with quite different values to those that had been dumped from a working system. I did the obvious and manually deposited at least the first few 'wrong' locations to the 'correct' values; the behaviour changed. Instead of halting with an error the run light stayed on but no utility menu was displayed; the machine was hung. I recently obtained and very briefly tried a second UC17 with similar results - except on this card (same firmware version) the values in memory prior to 'S 80' were even more 'wrong'. Haven't got further yet but will have a hack in a few days. Do you know beyond peradventure that the NPG wire-wrap IS removed? I don't and will have to check. My 11/730 also passed all diags - well until it got to the RL02 bit where it failed due to no RL02!

Wow good luck with that. In 20 years I've only ever seen *one* - mine. It was working a few years ago but it's currently dead and I'm not optimistic; power supply issues - but there also seems some kind of 'blotchiness' inside the plasma display sandwich itself - like something has delaminated or leaked or something. If you find a small herd of them I'd certainly be interested in getting hold of another one.

RE: Getting an ibm as/400
I agree little point in imaging. First step: password guess; try logging in to account QSECOFR password QSECOFR; you may luck out and find it is the default. If that fails do a DST IPL (Google it) and use the DST QSECOFR account (NOT the same as the system QSECOFR account!) to reset the system QSECOFR password. You may luck out and find that even if they've changed the system QSECOFR password from the default, the DST QSECOFR still works. If that fails you're down to a partial reinstall - 'slipping the LIC' as Benjamin described. There IS a way of breaking into a System/36 by patching specific sectors and offsets on the disk; I have it written down somewhere. But I know of no analogous procedure for AS/400.

Key thing is what color it is. If it's light grey it's definitely an old CISC machine - classic 48-bit AS/400. They're good and desirable but they do need the MULIC (Model Unique Licensed Internal Code) tape to get going. If it's black... Well some of the very last CISC AS/400s (e.g. 9406-500) were black - but it's much more likely to be a RISC machine. With those you get 70 days unlicensed use - then it reverts to only allowing login at the console IIRC; I don't recall what else stops working. Licensing on the RISC machines is just a long code you type in to the system; no MULIC tape! :) Another possible gotcha is keys; hopefully it comes with them. If it doesn't, hope the lock is in the manual position which allows full front panel function. Then there are password issues; QSECOFR is the key account - equivalent to root - and if you don't have that password you may be able to reset it using an alternate boot sequence involving something called DST... Unless they've changed the DST password too, in which case you can only wipe the system and reinstall the OS. If you need install media I can help...

Re: Shipping big things across the atlantic.
If you're in no hurry best bet is an international mover on 'consolidation' - basically it's delivered to the mover and it's loaded in a shared container and it only moves once the container is full. And if you can pick it up at the arrival end that saves big-time too.

Sun 4 disk images?
I'm presently working on a couple of Sun 4/110 systems. To save time, does anyone have a bootable Solaris disk image for such - to use with SCSI2SD? Note sun4 architecture - not sun4c or sun4m. Also may be on the lookout for a colour frame buffer; mine may be terminally flaky. Anything that works with a 4/110 - VME or P4 bus.

Nothing hobbled about them. And by the time Z-Architecture did come alone it was no longer necessary to use custom hardware to implement a usable mainframe CPU; it could be emulated entirely in software - Hercules; Flex/ES; z/PDT etc. - hence no 64-bit *hardware* successor to the P/390 was ever built or seriously contemplated.

IMO it's something > like a RX211 board for hard drives. Well you were right on the money! I found a manual for the thing. More precisely I found I had a manual for the QBus version of the thing squirreled away. Baydel called the entire Qbus subsystem the 'Baydel D405' - and Google returns precisely zero relevant hits for that search! I don't know what they called the Unibus version. The host interface (Unibus or Qbus) was indeed only half the system. Bayel referred to it as the 'I-board' (for 'interface'); it talked via the 40 pin connector to the 'P-board' (for 'personality') mounted in the drive chassis; the P-board did indeed implement the drive controller functions. The drive was a Pertec D8000 20MB Winchester; the drive chassis could contain one of these (which all my systems did) or two of these (which needed a special handler for the OS) or one 20MB hard disk plus one Shugart 8" floppy - which emulated an RX02. That all rings bells with what I had. Doesn't help much as the chances of me finding such a subsystem are tending to zero I suspect. But mystery solved!

Baydel Unibus disk systems
Folks, I've found something I forgot I had; a Baydel Unibus disk controller. At one time I had 3 or 4 of these in complete systems but carelessly managed to trade them all away(!) - except this one board. They were all identical; a pdp-11/04 with a quad Unibus Baydel disk controller hooked up to an 8" hard drive in a separate rack mount. In use the Baydel subsystem emulated multiple RK05s. The part number on the board is B01061. Unusually Google seems to be utterly silent on the subject; it seems Baydel and these products have slipped beneath the digital waves without trace. Does anyone have any information? I just have the controller board; I don't have any of the hard drives left. All I remember is the disk was an 8" and the interface is a single 40-pin cable; so not SMD and not SCSI. Far too early for IDE or ATA. Any suggestions for what the interface might have been and what disks might have been used? What hard disks were around in late 70s / early 80s that used a single 40-pin connector??

Xerox: MFM emulator: disk images available
I've been hacking Xerox recently and using Dave's excellent MFM emulator. I'm making two working bootable images available. One is Lisp - the 'Lyric' distribution. It boots and works and appears complete and useful but I haven't explored Lisp enough to grok it. The other is a clean install of Viewpoint 3.1 with document editor and a few assorted utilities and games - and terminal emulators. Both come with readme files and configuration info. They can be picked up at: http://corestore.org/vpemu.zip and http://corestore.org/lispemu.zip With a following wind I may get other Xerox disk images up in the not too distant future - Star; 8010 and 8090 servers for starters. Maybe a Medley Lisp system. I'd be interested in hosting any other useful images for disk emulation - not just Dave's and not just Xerox - SCSI2SD etc. too - that anyone feels like contributing.

VAX-11/730 success!
Thanks to those who helped and advised; I discovered a problematic pin on the TU58 10-pin DIP connector. With this fixed, TU58EM worked correctly and the console code loaded. The CPU passes diags as far as the RL02 test; not surprising as there's no RL controller or drive - or the special diag pack! - installed. On a point of order... is there any reason an Emulex UCxx Unibus SCSI controller wouldn't work in this machine? Anyone with any experience there? If it emulates an MSCP disk closely it should Just Work? I'm thinking a SCSI2SD solution to give me a reliable one-box system...

But the VAX still doesn't want to play; from the behaviour and messages it's falling over at exactly the same place. The Arduino serial console displays: Continue after 2 INIT flags. online! And VAX shows the now-familiar ?27 DEVICE ERROR... Which looks a HELL of a lot like how tu58em is ending. So I don't think the problem is with tu58em... Is there anything I should be looking at on the VAX end here? Any configuration or cabling details that could be screwing things up before I drag the RS232 analyser out? I've tried changing the 'delay' parameter on the Arduino to various values between 0 and 255 to no avail - and I've tried a couple of different tape images in case I got a bad one...

No worries I'll puzzle it out; the main branch tu58em builds cleanly with no issues on Linux. Mike http://www.corestore.org 'No greater love hath a man than he lay down his life for his brother.

I did wonder how one might go about writing a tape image to a physical tape... I'm happy to get the thing loaded via the emulator for now - but I'd like to get real working tapes eventually. If it helps your 'hard part' I have at least a couple of brand new TU58 tapes - still sealed in plastic wrap...

Mark, Actually I do have a Mac within easy range of the 730. Could you do me a favour and throw a prebuilt OSX binary somewhere I can grab it? I have flaky internet in the workshop and this Mac isn't set up with Xcode or any other dev environment...

That's my understanding too - complicated by the fact that are two Tx/Rx pairs for the two drives IIRC... http://www.corestore.org 'No greater love hath a man than he lay down his life for his brother.

Thanks for that. Are you able to provide confirmed working details & pinouts for the cable? IIRC it was just three wire; Rx/Tx/Gnd? Would help if I could have confirmed working setup there. http://www.corestore.org 'No greater love hath a man than he lay down his life for his brother.

Re: VAX 11/730 quickie
Well I haven't figured out exactly what the problem was but I'm embarrassed to report it was indeed serial comms finger trouble. I could have sworn that VT220 was fine and the cable wired correctly... but to cover all bases I tried it with a USB serial port on the Mac that sits in the lab. It worked. First time. CONV011 Bugger me. http://www.corestore.org/730cons.png OK next is console tape... I have around 100 TU58 tapes. On close examination the collection contained ONE console tape... for an 11/750 of course! So I'll be reaching for an emulator. Looking back at a long thread on vintage-computers last year it appears that tu58em had timing issues and was unusable on 11/730 but is now patched and working correctly... watch this space! Thanks for all the pointers.
