I Frankensteined a P/390 together out of a P/325 server and the PCI P/390 card back in the day. I assume you do have the LIC for the P/390 card, without which you?re dead in the water. At least the PCI model wasn?t picky about the disks it used. And I?m pretty sure it?ll work with whatever the final Warp Server release was (4, maybe?) by which time the native TCP/IP support was a lot better. It was a nice little machine for its day, although Hercules is now many times its speed on modern hardware. I used mine to run VM/CMS and Linux (under VM) quite well. Adam

Mostek MK50312

by ajwills＠scorchingbay.nz

Does anyone have any datasheet/hardware details of the early Mostek calculator chip MK50312N ? It may be listed in "Mostek, MOS Integrated Circuit Guide", 1975 - a magazine sized, 138 page, blue and silver book.? Which apparently covers the F8 and several early memory chips and some calculator chips. (Not listed in the Mostek 1974 "Integrated circuit guide") Any help would be appreciated, even just confirmation that it is listed in the '75 guide. --Tony

Modifying microcode

I'm pretty sure that I have a complete set of 11/730 TU58 tapes in my storage unit. I might even have some brand new tapes. If I can find them, I would be happy to send them to you. They have been sitting in storage for probably 20 years, so there are no guarantee that they are readable. I'm cleaning out the storage unit right now, in preparation for moving, so I'll keep an eye out for them. Alan "Pack rat" Frisbie

Logic Analyzer software for the HP-IB/RS-232 bus pre-processor HP 10342B

by marc.verdiell＠gmail.com

This has probably been asked before, but does anyone have the software package that came with the HP-IB/RS232 HP10342 bus pre-processor for the HP1650 series Logic Analyzer (actually I have a 1670G)? It should have a config file and an inverse assembler file. I'm interested in the HP-IB files. Can't find it anywhere. - Marc

M68020-PGA to M68EC020-PGA

by carlojpisani＠gmail.com

hi I am playing with an old Motorola board and I have a problem As you well know, the 68020 is a 32-bit microprocessor from Motorola, released in 1984. Motorola also manufactured MC68EC020 - embedded version of the MC68020 CPU, housed in different packages than the Motorola 68020 microprocessor, but even in the case of PGA package of 114-pin PGA, MC68020/PGA is not pin-to-pin compatible with M68EC020/PGA They both use 114-pin PGA package, but some pins are different, (Vcc and gnd are placed differenly in the pinout), and you need an adapter! My board's socket is designed for M68EC020, but I need to use a M68020 chip because only the goldcap version, i.e. MC68020RC33 114-pin ceramic PGA, is available at 33Mhz. Code: Select allCPU: MC68020 114-pin PGA ----[adapter] ---> socket: MC68EC020 114-pin PGA Do you happen to know *where* I can find an adaptor M68020-PGA to M68EC020 PGA? Do you happen to have for sale? here I am Thanks!

Fairchild 9440/445 MicroFlame?

by bob＠jfcl.com

I'm looking for manual scans, software, really any documentation of any kind for the Fairchild F9440 or 9445 (aka the MicroFlame) microprocessors. Yes, bitsavers and a few other places have datasheets for the chips, but that's really about all the documentation I've found. And yes, I know that they're Nova clones and can run DG software, but Fairchild had their own development tools too that seem to have disappeared completely. In particular, Fairchild had a single board computer for the 9445 called (I think) the PEP-45. It had a built in EPROM monitor called PEPBUG-45. I'd love to find manuals and schematics for that gizmo. Actually I'd be interested in documentation for any systems that used either of the 944x chips. Bob

It's more advanced and it can be used as mini Wiki - Chunks (of users/stuff) offers FTP-like with manuals and links to other sites bookmarks Durcheinander is an advanced area with the possibility for the (local, only from the local intranet) user to upload and execute JavaScripts, JavaAplette, Node.Js code, and Java bytecode. It's not yet safe enough to be open to the public Internet, and it stills needs to be hardened in its profile. Due to what happened in December 2017, cyber attacks destroying the whole website, it's a reserved chunk of priv? stealth rooms for the team, whose access from the Internet is reserved and features are reduced e.g. it checks the socket.connect.ip, and if it comes from outside the intranet it blocks the whole scripting-engine allowing just a plain text browsing. My participation to SGI is merely focused on my needs, as I'd like to port an HDL simulator to Irix. But I sold my Octane 1 year ago, and I am willing to sell my dual Tezro rack-mountable racks cause I lost enthusiasm. Anyway, does anyone happen to have a copy of an Ada95 compiler for Irix? Or a working copy of GNAT? Needed for IRIX >= 6.5.27 I will for sure sell the Tezro, Maybe I will reconsider the purchase of a tiny Octane. I am more focused on Linux/HPPA and Linux/PPC32, which are used for job tasks. At the moment. I am developing a fast FiberChannel ram-disk for the radio telescope. cheers

M6809E/63C09E databus behavior question

by brain＠jbrain.com

I agree this is very specific, but I thought perhaps someone could help. As I look at the '09 datasheets, I can't tell when the data lines become valid on a write cycle. I ask because I have created a few projects that place themselves between the CPU and the CPU socket (CPLD based). To play nice with a potentially shared address and databus, my code honors the BA and TSC lines on the IC.? If either line is high, as noted in the datasheet, I tristate the address and data lines. Otherwise, the address lines are valid during the entire E cycle. As for data, it depends on the state of the R/W line. If R/W is high, the external databus is connected to the CPU databus during the entire cycle if TSC and BA are both low. If R/W is low, I initially set the external data bus according to this assign statement: assign data_ext = (!r_w & e& !(tsc | ba) ? data_09 : 8'bz); The '09 boots, but certain devices fail to operate.? If I change the assign to: assign data_ext = (!r_w & (e | q) & !(tsc | ba) ? data_09 : 8'bz); or assign data_ext = (!r_w& !(tsc | ba) ? data_09 : 8'bz); The devices begin working. Either of the modified equations works, but I don't know if can safely place data on the external databus during the entire cycle, like the address lines, or if I need to be off the bus for some small portion of the cycle.? I was hoping the datasheets could help, but I am missing the key portion of the timing diagrams. I hope someone can enlighten me.? I have the system working, I just want to make it as good as possible. Jim -- Jim Brain brain at jbrain.com www.jbrain.com
