ISO: Harris Micro-12 (HB-61000) docs

by derschjo＠gmail.com

Hi all -- Got me a Harris Micro-12 (AKA the HB-61000), this is a single-board computer based around the Harris 6100 (PDP-8 on-a-chip) microprocessor.? I'm working on bringing it back to life and I'm trying to find docs and schematics for it. There's a high-level overview starting on page 5-4 of http://bitsavers.org/components/harris/1979_Harris_CMOS_Microprocessor_Volu…, but that's the most I've found.? Right now it looks like the FLAG 2 signal on the PIE chip (HD-6101, discussed in the aforementioned manual) is holding the 6100's RUN line low; I don't see anything telling the PIE to do that at reset, nor is anything else attached to that signal that I've been able to find, so I'm wagering that the chip is faulty at the moment.? (If I pull the PIE chip out the CPU appears to be running.)? Schematics and/or docs would make this a lot easier. Anyone have a copy of these? Thanks in advance, Josh

UCSD p-system manuals and disks?

by mattislind＠gmail.com

I received these nice binders. https://i.imgur.com/L80ZGusl.jpg I think that most of them are already available online. Not sure about the UCSD Pascal manual? One of the binders contained some disks. https://i.imgur.com/FYIBbmjl.jpg Are these disks available online already or should I dump them? Bitsavers seems to have the Mac version. /Mattis

AlphaServers

by BHuntsman＠mail2.cu-portland.edu

Place your wagers... How many more years do you think it'll take before decent, practical-sized Alphas, like the DS15, and to some degree, the DS10, will be obtainable at hobbyist-friendly prices? I have an ES47 I got for a price I could stomach, but it's sans rail kit, drinks power like it's going out of style, and can anchor a 40-ft yacht. Anyone out there do Alphas anymore?

Four Unibus boards from radiation dose measurement system.

by mattislind＠gmail.com

Hello! I have four unibus boards that came in a 11/34 which was used for radiation dose measurement at a hospital. Three of them are made by Computer Design & Application inc and is a three board set interconnected with over the top flat cables. It has some kind of AMD 29xx based bitslice processor with 2903,2910 and 2914 chips. One board has some kind of dedicated memory one board has 4 TRW chips which I think are AD converters. https://i.imgur.com/lMvhxOp.jpg?1 https://i.imgur.com/LEVN5Qp.jpg https://i.imgur.com/kcSnDRy.jpg https://i.imgur.com/ZfFrq3j.jpg Then there is some kind of serial com board with four UARTs on it. https://i.imgur.com/YvnTlxq.jpg Is there any interest in these boards? Trade for something interesting DEC stuff maybe? Or something else? /Mattis

Compaq Storageworks V5.4 kit for SUN Solaris

by Flash688＠flying-disk.com

I'm cleaning out my accumulation of "stuff" and there are several things that aren't worth the effort of putting on ebay. If anyone on this list wants them, they are yours for the cost of shipping. The first item is: QB-5JCAG-SA Compaq Storageworks RAID Array 450 V5.4A Platform Software Kit for SUN Solaris Contains: AG-R20SE-BE Software CD "RAID Array 450 V5.4A for SUN Solaris" AE-RBDYB-TE Software Product Description SPD 64.64.05 AA-R20TD-TE Release Notes AA-R20RD-TE RAID Array 450 V5.4 for Solaris 2.x Installation Guide AA-R24LA-TE StorageWorks Command Console (v1.1) User's Guide EK-HSZ50-CG HSZ50 HSOD v5.1 Array Controller Configuration Manual EK-HSZ50-SV HSZ50 HSOD v5.1 Array Controller Service Manual EK-HSCLI-RM HSZ50 HSOD v5.1 Array Controller CLI Reference Manual It weighs just under 5 pounds, so I estimate the shipping cost would be $10 to $20. Send me an email if you want it. If I don't hear from anyone in a few days, it goes into the dumpster. Alan Frisbie

ounting screw threads for VR201?

It's likely > larger than 1/4-20 from what I remember. There are four brass inserts in a trapezoidal pattern, each threaded 1/4-20 (National Coarse). The trapezoid is 7.0" center-to-center for the two nearest the screen, and the rear ones are 5.0" center-to-center. It is 5.0" between the front (screen) pair and the rear pair. This is for a VR201-B -- other dash-variants may be different. If there is a base with a single large threaded insert, it may be an adapter that goes between the VR201 and the stand. Now, could someone please tell me the pinouts for the 15-pin connector? I would like to use it to view RS-170 video, if possible. Alan Frisbie

Mounting screw threads for VR201?

by ethan.dicks＠gmail.com

Hi, All, I don't happen to have a VR201 here right now to measure directly (or I would just do that), but IIRC, there's a threaded mounting insert on the bottom (for the "E.T. Stand", if nothing else), I want to fabricate a shelf clip for a VR201 and am seeking the diameter/thread pitch for the insert. Does anyone have that info handy? It's likely larger than 1/4-20 from what I remember. -ethan
