IMSAI EPROMs

by jweder＠telusplanet.com

Tony... Even better idea! Yeah, I was a bit bothered by the idea of hacking this nicely built Godbout EconoROM board. Might just try your idea, though not THIS month! Life is too dang busy! (sigh) Joel A. Weder jweder(a)telusplanet.net 403-556-4020

IMSAI EPROMs

by jweder＠telusplanet.com

Thanks to everybody who's replied about how to read these EPROMs. I'll likely be contacting somebody within a couple of weeks to get it done, or I MIGHT get crazy and buy a Data I/O 29B burner (tho I'm not feeling all that wealthy right now!) I like Dick's idea of modifying the board for 2716's after getting the data read out of the 2708's mind you... It'll be interesting to see what's on these dang things. I have an idea one program might be some kind of ham radio software, as I just found some pencilled notes about AFSK and CW outputs to one of the ports. Sure be nice to find BASIC! Joel A.

sol-20 + Helios II system score, plus plea

by frustum＠pacbell.net

Well, sometimes great things just happen when you aren't looking. Friday night I got an email from a woman who lives 10 minutes from me. She was moving and had a Sol-20 with a Helios II disk system and would I want to take it? Needless to say, I did. I'm a happy guy. Well, I was before I got it, so maybe I should say even happier guy. There are two problems: although she had about 8 8" floppies, only one of them appears to be hard-sectored, which I think the helios system was. Second, although there is a very nice persci manual, the manual containing the technical information (programming, schematics, theory of operation) for the two-board disk controller wasn't to be found. So, a few pleas: 1) Does anybody have the technical docs for the P.T. disk controller for the Helios system? 2) Does anybody have any disks images for the Helios? Any disks? Bob Stek was kind enough to supply me with a copy of a listing of the source code for PT-DOS, but OCR'ing and correcting over 200 pages of source code in a very small font might be too much to take on. 3) What should I do with my one disk that might work with this system? 3a) Just try and boot off of it 3b) Try to tune up the persci disk (and maybe make it worse) then boot the disk 3c) Find a service that specializes in recovering data from old disks On 3a, I'm discouraged from doing this as the cabinet is full of dust and spider carcasses. If I do a thorough job cleaning, then perhaps as long as I'm there I should adjust things. On 3b, has anybody done this (back in the day)? Is it for mere mortals, or does it really require special skills to prevent making things even worse? On 3c, does anybody know how much that costs for doing just one disk? Ten disks? Are there any risks of the disk getting trashed? My ultimate hope is to get PT-DOS running on Solace. I know it is a pain to dig out old docs, but if you have them, please contact me and I'll try to work out something with you to make it worth the effort. (BTW, a few weeks ago I updated Solace to fix a few bugs and add a few minor features -- it is at version 2.3 now: http://www.thebattles.net/sol20/sol.html http://www.thebattles.net/sol20/solace/solace.html ) Thanks. ----- Jim Battle == frustum(a)pacbell.net

DEC Searchings

by SPEDRAJA＠mail.ono.es

Hello from Spain. I give all of you a little list of DEC old items I'm searching actually: * VT100\VT102 terminals (until FOUR) with cables. * VT52 terminals (until FOUR) with cables. * TU58 tape unit with cables. * External tabletop DEC rack or support structure for 19" items. * RX02 disquette units cabinet with two disquette units + controller + cables * RL01/02 disk unit (TWO) + controller + cables * One paper tape reader/puncher * One card reader/puncher * One LA100 or similar terminal/printer In CPU's chapter... * One VAX-11 of little size, with disk and tape unit (and even better with diskette unit(s) ). * One PDP-8 cpu minimally operative * One UNIBUS PDP system minimally operative. If somebody has this items in Europe and with 220 volts power supply unit it would be better. With spanish keyboard it would be wonderful, but not imprescindible. I know about shipping cost matters, but is not neccesary to locate and ship all items at same time, etc. You can contact in my e-mail address. Thanks for all and best regards ---------- Sergio Pedraja Santander Spain ---------- mailto: spedraja(a)ono.com ----------

All states have had tornadoes, some just more than others

by mmcfadden＠cmh.edu

Today I drove through Pleasant Hill, Missouri, the site of one of NOAA's weather radar units. Large radar dome on a stand, it's pretty neat to see the radar track of a severe storm, especially when I'm within 7 miles of the radar. I can go online on the cable modem and watch the storm real-time >from the NOAA radar. When the neighbor's boat and dock flipped upside down into the yard I knew the wind was howling. It's only a tornado if the house explodes and there's not much left standing. Straight-line winds are more common. I tried to tour the place during an open house but the line was 1/2 mile long.

OT: PC AGP slots

by healyzh＠aracnet.com

OK, this is seriously off-topic, but I know someone around here has to know, and I'm not sure where else to ask. Can you put a AGP 2x or 4x card in a system that only has a plain AGP slot? I've got a PII/333 in a 440LX system I'd like to put something like an ATI All-in-Wonder Radeon card into. Zane -- | Zane H.

Booting RSX-11M On A PDP-11/34

Assuming you have a standard DL11-E or DL11-W, you do have the settings correct. Some third party serial cards (and some DEC multiplexers) have software-programmable baud rate, but not the standard DL11s. It's possible that RSX is faking the parity, but that would be easy to check by setting the LA120 to 7E1 (or, less likely, 7bits, odd parity, one stop bit). > I'm not sure I have all the right packs mounted, because > A) I only have 2 of the 3 drives connected, and > B) the labels on a lot of the packs are faded, or have come off > completely.

How many RL01 packs does an > average RSX-11M installation use? If you have a non-bootable pack mounted it should print a message on the console and then halt. Or maybe just halt (I can't remember for 3.1). If you have a bootable pack, it should boot (not surprisingly!) and print stuff on the console but it might complain about hardware being offline if you don't have the same setup it was built for (eg missing serial lines or missing disk packs). A normal RSX 3.1 installation would use 2 x RL01 or 2 x RL02. Fitting a useful system into a pair of RL01s is a bit of a squeeze, and building one like that is a pain, which might explain why you have three drives. > Also - do the drive numbers (0,1,2...) > depend soley on the order they are connected in? They don't depend at all on the order they're connected in. The depend only on the unit select plug (the white one with the number on it) plugged in to the front panel of the drive. Usually the system would boot from drive 0. -- Pete Peter Turnbull Network Manager University of York
