Help Identifying Mystery SBUS Cards

by classiccmp＠jouhe.org

Hello all, I was hoping to tap into the considerable Sun Microsystems experience within this group. I picked up a significant quantity of Sun SPARC equipment back in the early 00?s and due to life/children/etc. have only recently been able to start cataloguing it. In particular, I had a somewhat tatty box full of assorted SBUS cards. Amongst the usual GX / TGX frame buffers, ethernet and narrow SCSI cards were some more unusual ones I?ve struggled to identify. I have photographed (poorly, I only have my mobile phone camera) the items, and they can be viewed here: https://www.dropbox.com/sh/kv42ig8nucikt0p/AAAKMZkqn9r19Ti0yKllQ2g8a?dl=0 <https://www.dropbox.com/sh/kv42ig8nucikt0p/AAAKMZkqn9r19Ti0yKllQ2g8a?dl=0> Here is a text description of the cards, in case it can be useful: (1) A dual-width SBUS card with no internal or external interfaces or backplate. Other features include 2x LSI chips 'LIA7321 EK7B7483' and 'LIA6371 EK7B7484? and a sticker displaying '7B7488 011 0110-014 0643 1700556 9651? a barcode ?J0BAW?. I wondered if it might be a DSP of some kind? (2) A dual width SBUS framebuffer, with space for a piggyback daughter SBUS card in the middle. It features 3 x Bt457 RAMDACs and an Actel A1020A chip. (3) A 3M fibre card, looks like a prototype based on the number of bodge wires. FDDI? Marked '3M ASSY 78-8095-5382-5', ROM marked FOSSIL BD. 1AS8. (4) Possible Serial card with a DB9 connector, although there?s WAY too much logic for a simple serial card. Has a jumper for 4Mhz / 16Mhz which hints at maybe something Token-ring? (5) A SBUS card with S-Video and what I assume to be composite. Looks like a 501-3019 on first inspection but there?s less logic and no heatsink on board. (6) A rather beautiful (to look at) SBUS card by Performance Technologies Inc. This one strikes me as a multi-port serial card although I don?t have the breakout HD80 lead for it. Has a chip marked 820P010201 HG62S038R02F 9120, a sticker ?120P010001' and on the back of the board '#595801-01 DC 9116 NT2V0 94V0' and '124-010000?. Any insight would be gratefully received! Thanks, Austin.

OT: SiC Radio for Venus lander

by rdbrown0au＠gmail.com

Alan Mantooth, Carl-Mikael Zetterling and Ana Rusu (28 April 2021) "The Radio We Could Send to Hell: Silicon carbide radio circuits can take the volcanic heat of Venus" IEEE Spectrum https://spectrum.ieee.org/semiconductors/materials/the-radio-we-could-send-… "The average surface temperature on Venus is 464 ?C, the atmosphere is dense with highly corrosive droplets of sulfuric acid, and the atmospheric pressure at the surface is about 90 times that of Earth." (Teflon melts at 327 ?C) The following thesis describes the Vulcan II chip mentioned a bit more Benavides Herrera, Maria Raquel, "An RS-485 Transceiver in a Silicon Carbide CMOS Process" (2018).Theses and Dissertations 3067 "The RS?485 was designed in a 1.2 ?m SiC CMOS process technology developed by Raytheon Systems Limited (UK) called High Temperature Silicon Carbide (HiTSiC?). The components available in this process include: NMOS and PMOS devices, on-chip resistors, diodes, and capacitors. The process key features are given below: ? 4H-SiC process ? N-type substrate ? Supply voltage of 15 V 5? Single metal layer, two layers of polysilicon (one being high sheet resistance poly) ? Operating temperatures greater than 300?C" ... --- In 1988's 1.2?m CMOS process the MIPS R3010 floating-point coprocessor was about 75,000 transistors on an ~8mm x 8mm die. Are there markets for SiC CMOS devices with large transistor counts? Watching Curious Marc's video mentioning Triton missile/Saturn V bit-serial computer implementations, reminded me of: Olof Kindgren (2019) Bit by bit - How to fit 8 RISC-V cores in a $38 FPGA board https://riscv.org/wp-content/uploads/2019/06/12.15-SERV-Zurich-Copy.pdf https://github.com/olofk/serv "SERV is an award-winning bit-serial RISC-V core" (RV32I) (Not an engineer - guessing) If process limits mean large SiC memories are unlikely, what other technologies would work in the 400?500?C temperature range? Magnetic bubble memory? Twistors if threading cores automatically remains infeasible? For cameras could you build vacuum tube sensors containing SiC devices if useful?

In search of RLX blade software

by camiel.vanderhoeven＠vmssoftware.com

I?ve been given a couple of RLX blade server chassis loaded with blades (one with Transmeta Crusoe cpu?s, and one with Pentium III cpu?s). I hope you?ll allow me to count these as ?vintage? because of their interesting origin: the Pentium III loaded chassis was part of a 768 node computer cluster at the Sanger Institute in the UK, and was used in the last stretch of the DNA sequencing computations for the Human Genome Project. I?d like to build a compute cluster out of these, but I don?t have the rpm?s they supplied to customize Linux for their blades. Ideally, I?d hope to find a copy of their ?Control Tower? blade management software, and their customized Linux installation images, but just the bare rpm?s would do for now. From the RLX platform guide, I?d hope to find: kernel-*rlx*.i386.rpm kernel-headers-*rlx*.i386.rpm devfsd-*rlx*.i386.rpm ucd-snmp-*rlx*.i386.rpm net-snmp-*rlx*.i386.rpm ucd-snmp-utils-*rlx*.i386.rpm net-snmp-utils-*rlx*.i386.rpm bootctl-*rlx*.i386.rpm atftp-*rlx*.i386.rpm lm_sensors-*-*rlx*.i386.rpm lm_sensors-drivers-*-*rlx*.i386.rpm lm_sensors-devel-*-*rlx*.i386.rpm base-utils-*rlx*.i386.rpm runctl-*rlx*.noarch.rpm networkcfg-*rlx*.noarch.rpm mgmtmode-*rlx*.noarch.rpm namedcfg-*rlx*.noarch.rpm dhcpdcfg-*rlx*.noarch.rpm lilo-*rlx*.i386.rpm grub-*rlx*.i386.rpm rlx-clientpm-*rlx*.i386.rpm This e-mail (including any attachments) may contain privileged, confidential, proprietary, private, copyrighted, or other legally protected information.

Lecture: How I ported Space Invaders to a video game console from 1978, 2021-07-10, 19:00

by stueberahoo＠yahoo.de

Hi all, you're invited to the Update computer club[0] public lecture series "Updateringar"[1]! Update is a Swedish computer club founded in 1983 whose members tinker with all kinds of computers, from Raspberry Pi to PDP-12. The club has a big collection of historic computers. In this lecture series we'll talk about everything related to computers: Historic and modern computers, operating systems, programming, hardware projects, creating art with computers, building a computer museum, and more. When: 2021-07-10, 19:00 CEST Where: https://bbb.cryptoparty.se/b/upd-0mo-m2u-aq8 How I ported Space Invaders to a video game console from 1978 Bjarni walks us through his recent port of the arcade classic to the Philips Videopac, a second-generation video game console. He explains the hardware limitations and shows tricks used to get around them ? unlike in the arcade machine there is no frame buffer, and the functionality of the hardware sprites is severely constrained on the Videopac. The development of the port was done on real hardware with a home-made USB-connected game cartridge. Bjarni Juliusson (Update) The lecture is free and open to everyone. Upcoming: 2021-08-14, 19:00: The Whirlwind I. Angelo Papenhoff (Humboldt University of Berlin) Hope to see you there, Anke [0] http://www.update.uu.se/index_eng.html [1] https://www.update.uu.se/wiki/doku.php/projekt:updateringar

FTGH for pickup in So Cal: PDP-11/44, Macs, Atari ST, RiscPC, ...

by spectre＠floodgap.com

Well, the pandemic turns everything upside down and we're looking at new employment, a new place and probably having to slash a few things. First on the chopping block is to consolidate and downsize storage. These systems and peripherals are all free to a good home; all you have to do is pick them up. Pick up any and all, with priority given to those who are interested in multiple units. I've tried to describe them as completely as possible. A few items have "on your honour" conditions. I'm also giving priority to classiccmp readers before I post public elsewhere. The items are in various places over the Riverside-San Bernardino area in Southern California depending on where and when I acquired them, so send me an off-list E-mail and we'll figure it out based on their location. THESE ITEMS NEED TO BE GONE IN THE NEXT MONTH. If you need a little extra time, we can work something out; I'd rather not scrap what someone has an interest in, but obviously with a likely move approaching, the sooner the better. =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= POSSIBLY WORKING: PDP-11/44 with at least four disk packs and lots of paper tape and 8" floppies, sitting on top of what I think is a TU58. I never got the chance to fire it on. You will need a truck, probably a cart and definitely a hernia belt. There is also a big Kennedy disk next to it but I don't know if they originally went together. POSSIBLY WORKING: DEC VT100. This got bashed around a little and the case is a little loose, and I don't know if it works, but it's an honest to Ford VT100. NOT WORKING: Alpha Micro S-100 system. I got this when I had more money with the intention of rehabilitating it when I had more time, and now I have less of both. It will work for other S-100 cards. Whatever cards and devices are in there are all yours. They are heavy steel drawers and it can take big cards. There are two boxes; please take both. NOT WORKING: Acorn RiscPC 700 and Castle Iyonix PC. Like the AM S-100 system, I got this when I had more money but not enough time, and now I have neither. They need specialist restoration as neither system powers on, and it doesn't appear to be (just) the PSU. In particular, the RiscPC came to me with a leaky board battery which may have something to do with it. Both systems appear heavily upgraded but I don't have any inventory. If you are interested, it is expected you will be restoring the systems and not just turning around to part them out; there aren't that many of these machines on this side of the Atlantic (on your honour). Please take both units; you will get a big box of software and RiscPC artifacts from the previous owner as well. WORKING: Snow iMac G3 (600MHz, 512MB RAM). Works fine, comes up in stock 10.3.9. Needs a new PRAM battery but in good shape otherwise. Add your own USB keyboard and mouse. This was a gift from a good buddy, so it goes to you with the understanding you will try to find it a home if you don't want it instead of trying to sell it (on your honour). Everyone should have the joy of an original iMac. NOT WORKING: Atari STacy, disassembled. I was working on the system to replace the hard disk and one of the power headers got shifted which put 12V on a 5V line. Guaranteed this liberated some magic smoke from the motherboard or a yet-to-be-detected fuse somewhere, but the keyboard, RAM card, screen and such were all functional at the time I effed up and probably still are. You will get it in a fabulous Office Depot box with "STacy" written on it using a half-dead Sharpie. POSSIBLY WORKING: Mega ST4 with Megafile 60 and SC1224 and SM125 monitors. These are a bit yellowed and the keyboard is thrashed. Also, the TOS is on a separate card with two leads that got loose and I don't know where they go (probably to +Vcc and a select pin). Thus, can't test the monitors or the hard disk, but the system does power on, and the hard disk does power up and makes happy hard disk noises. No idea what's on it. The SM125 puts on a power light and does appear to try to make a picture, though its previous owner separated it from its stand for some reason. The SC1224 sounds like the flyback is bad but may be serviceable. Includes ST mouse and hard disk cable. No manuals or software. If you want this unit, you need to take everything including the monitors. NOT WORKING: Breadbox NTSC Commodore 64, in original box with power supply. Last time I powered it up, it generated a garbled display that suggested either bad RAM or PLA. You get to find out. PROBABLY WORKING: Tandy Color Computer 2, in original box. Was working when stored. PARTIALLY WORKING: Quad G5 2.5GHz x2x2, 8GB RAM, Nvidia 6600. Got whacked in shipping and one side of the case is damaged. No hard disk. Does power on and starts Apple Service Diagnostics fine, but the fans roar like the MGM lion and while there is no obvious leak you will need to service the liquid cooling system -- you're not thermal calibrating your way out of this one. Has the wireless card. Aftermarket optical drive needs "help" when you eject it. Add your own USB keyboard and mouse. NOT WORKING: Macintosh SE/30 (marked "Lake Washington"). 8MB RAM. Powers on and bright display on the monitor but Simasimacs immediately. Probably fine with a recap. Case yellowed as hell. I think I removed the hard disk, but if not, hey, free hard disk. Add your own ADB keyboard and mouse. NOT WORKING: Macintosh SE/30 (marked "Clover Park"). Also used to be my file server but then Simasimaced and now doesn't put a picture on the screen at all. Undoubtedly needs a recap and may need other repairs based on the funny pulsing of the system fan when connected to power. I think it had 4MB of RAM, don't recall exactly. I think I removed the hard disk, but if not, hey, free hard disk. Add your own ADB keyboard and mouse. PARTIALLY WORKING: Sawtooth Power Mac G4 450MHz. No RAM, no video card, no hard disk. Used to be my file server but had issues with one of the PCI slots. Has optical drive and ZIP with matching Apple bezels. Does power on, but obviously without RAM or a video card (AGP) will not pass POST. Add your own USB keyboard and mouse. NOT WORKING: Quad G5 2.5GHz x2x2, 16GB RAM, Nvidia 6600. This is in better physical condition and does power on and bong but shortly afterwards puts on OVERTEMP and CHECKSTOP lights, so you definitely will have to service the LCS and possibly the processors (no obvious leaks but I haven't checked thoroughly). No wireless card, no hard disk, OEM optical drive, add your own USB keyboard and mouse. NOT WORKING: Single G5 1.8GHz, 2GB RAM, GeForce 5200. The previous owner seemed to have had a disagreement with the front panel connector and the front panel connector lost. I received it stripped to the chassis except for the processor and the logic board, but it does have the fans, video card, wireless (with T-antenna), power supply and panel cable. Because the front panel connector is busted I can't test it. You get to replace the front panel assembly and put it back together. This unit is air-cooled, but probably could benefit from reapplying thermal compound while you're at it. Has optical drive (disconnected), no hard disk, add your own USB keyboard and mouse. Various other items: Newtek Video Toaster 4000 and Video Toaster Flyer boards with a whole mess of cables (looks like SCSI and some other internal pin header-type). Don't know if these are complete and no way to test. No software. Apple II Super Serial card with DB-25 670-0020-? (uses 6551 ACIA) and Apple IIe 80 column 64K memory expansion 607-0103-K. Can't test them but both look intact. Kurta Penmouse. Serial and PS/2 connectors. Seems to have a power supply jack (9V) but I don't have the power supply and I don't know if it needs it. Can't test it, no drivers, physically intact. Sun model 411 SCSI CD-ROM. Requires caddy. Won't mount discs, might need a recap. UMAX Astra 2100U flatbed USB scanner with power supply. Powers on. Works with classic Mac OS but probably most systems. No driver disc. Pair of Telular SX5 GSM terminals. These were the server room's backup communication system. They work, but no GSM network to connect to anymore. Might be fun if you set one up. Real serial ports! Real GSM modem! Full kits with power supply. Visual UpTime Select T1 CSU/DSU. Has a Cisco V.35 cable connected and jacks for Ethernet, serial, DSX-1 and T1. Powers on, obviously goes right into Red Alarm since there's no network. You telco nerds will love it. Various complete external modem packages ranging from 14.4 to 33.6K. -- ------------------------------------ personal: http://www.cameronkaiser.com/ -- Cameron Kaiser * Floodgap Systems * www.floodgap.com * ckaiser at floodgap.com -- The cost of living has not adversely affected its popularity. --------------
