If my house were on fire and I had to pick what to save, near the top of my list would be my MicroVAX in a BA123 enclosure. It is by FAR my favorite computer. Sadly, there was a tragic accident and the ventilation louver, just about the power switch got broken. I know, I know. How could this happen? I am overcome by guilt. I can't rest until my poor, sad VAX is fully repaired and back to it's perfect condition. I've tried to repair it, but not had satisfactory results. Is there anyone out there that would be willing to sell me a replacement?

seeking EK-OLA30-OP - LA30 DECwriter User's Manual

by nw＠retrocomputingtasmania.com

Not an essential manual but for completeness I would like to find a copy. If anyone has one would they be willing to scan it please or I can arrange to get it done. The list of manuals for the DECwriter I LA-30 are: (missing) EK-OLA30-OPLA30 DECwriter User's Manual (online) DEC-00-LA30-DC1972-08LA30 DECwriter Maintenance Manual (online) LA30 Engineering drawings Nov-1973 (online) via Manx or bitsavers. If anyone has paper for these printers in the right size I'd be glad to have some (whatever would fit in an large envelope). LA30 is fixed sprocket position, needs 9-7/8 inch wide (1/2 inch pitch x 0.150 inch diameter feed holes) continuous paper.

Olivetti M24 Mounting Bushes for Bus Converter

by robert.jarratt＠ntlworld.com

The M24 I got the other day has the bus converter, whereas the other M24 that I already had does not. I bought a bus converter for the "old" one, but then realised I didn't have any mounting bushes or spacers in order to install it. I thought of removing some of the bushes from the new one to share with the old one, it wouldn't be as good but at least I would be able to install the converter. It looks like I might need some kind of special tool to remove the bushes >from the new machine. Is there a way to do this with ordinary tools? Does anyone know if the mounting bushes are any kind of standard part that could still be bought somewhere? Thanks Rob

Need info for a VAX Station 3100 SPX / VS42A-DA

by pete＠petelancashire.com

Won the guy on the big auction site, put the minimum bid down and $50 later it showed up on the doorstop. http://petelancashire.com/gallery/main.php?g2_itemId=6027 Sorry for the bad photo's but the sun was going down fast. Been trying to find the display interface specs, pinout, freqs, etc. but so far have been overwhelmed with just about everything else. Other things I guess I'll need are Also what keyboard should I be looking for ? What options do I have for an O/S ? The last time I logged into a VAX was one of many 11/780s the company I worked for was like 198? something. A LONG time ago .. -pete

Looking for M865 serial card photo

by v.slyngstad＠frontier.com

Hi, I'm putting the finishing touches on my efforts to re-draw the M865 schematic for the website www.so-much-stuff.com (which has a collection of similar drawings). I am looking for photos of the front and back, reasonably square-on, with enough resolution and light to make out the traces easily. My intent is to "trace over the traces" with my CAD software (Eagle 6.6), to document the board while simultaneously verifying the work I've done to draw the schematic. Does anyone have photos of the component and solder sides of an M865? It's the older Omnibus serial card, with the current loop cable soldered in. Permission to use the photos on the website would also be great. The folks I've found so far who own boards can't get photos of them for a week or more, and I'd like to finish these drawings before my motivation fades. (I know from experience how long it can take me to get back to half-finished projects!) Vince -- o< The ASCII Ribbon Campaign Against HTML Email!

Sun keyboards, yellowed

by sales＠elecplus.com

I collected some Sun keyboards for a customer, but some are too yellowed for him to use. They are all complete, including the cable, if it is supposed to be attached. I am asking $10 each plus shipping. They are not tested or cleaned. I don't have any Sun terminals left to test them on. Type 4, qty 2 (deeply yellowed) Type 6 USB, Unix, qty 10 (moderate yellowing) 320-1273 Type 6 USB Unix, qty 12 (no or very slight yellowing) 320-1273 asking $20 each plus shipping Cindy Croxton --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus

R: RE: RSX-11 trouble

by supervinx＠libero.it

Here I am! RSX-11M V4.2 BL38B I have two RX50 disk units and Kermit. 512kb and one RD51 fixed disk. I planned to archive separately every [*,*] and image the disks. I tried and can write back and read RX50 disks with a properly setup PC. I need only RSX-11M installation disks images but I'm confident they can be found somewhere on the net. I'll give a look to BRU... Thanks!

RSX-11 trouble

Ok, if you don't have [3,54] then you must have RSX-11M not RSX-11M+. In that case you should have two versions of Indirect: [1,54]ICP.TSK [1,54]ICX.TSK ICP.TSK is the default, "full capacity" version and in V4.0 of RSX11M it shows up under TAS as: >TAS ...AT. ...AT. 1.0 GEN 64. 00060000 LB0:-00114253 so try removing it as you did above and then INS the ICX.TSK and try it. >REM ?AT. >INS [1,54]ICX.TSK >TAS ?AT. ...AT. 9.01 GEN 64. 00060000 LB0:-00114033 It would be good to know which version of RSX-11M you have and also a bit about the configuration. You mention backing up your data, what disks do you have? To back up a system disk sometimes it is best to use BRUSYS.SYS which on M should be in [1,51] It is a memory resident version of BRU (running under RSX11S) that you BOOT and then can copy disks. Good Luck! Mark

MiST - Amiga ST FPGA + intro

by swiftgriggs＠gmail.com

http://lotharek.pl/product.php?pid=96 I recently picked up one of these devices. I'll apologize in advance if you folks have already had a discussion about the MiST. Basically, it's an FPGA that's capable of emulation (for lack of a better term) of many platforms on a hardware level. I only got mine about two weeks ago, and I'm still sifting through a ton of material and focused mainly on the Amiga and ST platforms (stuff I played with as a pre-teen and teen). I have to say, so far it's pretty awesome. The coolest feature in my opinion is the standard joystick ports on the side that "just work" with all the emulation targets. I always favored using Sega Genesis controllers in those (rather than the rinky-dink little "red joystick" of the time). They work oh-so-great with this rig. The only issue is finding a monitor that doesn't have a fit over 15Khz refresh rates. I use an NEC MultiSync with sync-on-green and all that fun stuff. I'm still busy getting AROS running on "my Amiga" (which is represented by an SD card with my ROM image from my A3000 and a metric crapton of floppy images). You basically hit a keystroke or joystick combo and you can swap floppies, reboot, etc.. If you are into any of these, I can recommend the MiST: * ST/STE (also on SCART 15KHz) * Amiga 500/600/1200 ( AGA CORE BETA core) * C64 (partially - still developed) * Atari 8bit ( 96%) * Collecovision * ZX81 * Atari 2600 * ZX Spectrum with AY, aslo with DIVMMC and ESXDOS * SEGA GENESIS * Apple II(x) * MSX * AMSTRAD CPC (BETA) * A few others, you'll want to check. BTW, I'm new to the list (1st post). So, I'll introduce myself. I'm just another IT worker with a background in Unix systems. I'm 41 and I started with HP-UX 10.x (high school) and branched out to every kind of Unix box I could get my hands on (Yes. I'm one of those Unix zealots, but that might be too gentle a description). I spent the 90's with SGIs (which I still collect, I have an O2+, two Indys, and a bruzin' Tezro fully built out). I spent the early 2k's coding for supper as a "security engineer" (read: writing exploits which I don't much care for now) and some stints as a Tru64 admin. On the in between gigs and contracts I've touched just about everything (and in the last 10 years a lot of new Unix hardware). I've professionally admin'd or coded for IRIX, Solaris, Linux, Tru64 (OSF/1 or Digital Unix for some), FreeBSD, HP-UX, UNICOS, and AIX. As a hobbyist, I've also tinkered greatly with NetBSD (maybe my favorite), OpenBSD, and Minix. Then of course there is the spacey or rare stuff I've put hands on. I'm talking about things like UnixWare, Xenix, SCO, SunOS, BSDi, DG/UX, NeXTStep/OpenStep, A/UX, and even non-Unix stuff like Sprite, L4, QNX, HURD, BeOS, Haiku, AROS, Genode, and others. I code fairly well in C, shell script, and TCL. I code not-as-well in AREXX, Python, Ruby, PHP, Lua, and a few other scripting languages. I'm pleased to be on this list, and to make your myriad acquaintances. -Swift PS: My spell checker needs and ex-lax after going insane over this email full of Unix variants and ancient platforms.
