Interesting... PDP-8/m Mem problems

by healyzh＠aracnet.com

OK, granted I don't know what I'm doing, but... I don't think there is anything wrong with the G104 board. I've been examining E24 and E28. The problem with E28 is it's not getting any input, and unless I'm mistaken E24 isn't either. The board is broken into 3 sections, and I've also checked the section next to it to get a better idea of what I should be seeing. Now for some very un-technical talk. I've been trying to find the lines that bring the bits from the Core board to the G104 board. As far as I can tell the bits are brought over on the back side of connectors 'F' and 'G'. There are 12 dual pin groups. The four that correspond to E24 and E28 aren't acting right. With the logic probe, when examining locataions, I only get a beep on the 8 that are acting right when it checks Memory locations: xxx0 - xxx3 (the ones effected by the bad 8251 on the G227 board). On the other 4 I always get a beep, no matter what location. So.... My conclusion is that the section on G104 that contains E24 and E28 isn't getting any bits, and may very well be a totally functional section. Having said that, I'm more than a little stumped as to how to attack the Core Board itself seeing as how it's sandwiched between two other baords. Zane | Zane H.

>The SCSI<->SMD configuration still eludes me, however. I know >they exist (Adaptec ACB-55xx), though I've never seen one. I believe the Adaptec boards are what were bolted onto the Fujitsu SMD drives I saw with a SCSI controller on them. I want to say that I've seen some OMTI ones too, but those may have been SASI. At one point I had a Pertec Formatted <- SCSI bridge, but it never interacted well with the hardware I wanted to use it with so it got traded away. -- Tim Shoppa Email: shoppa(a)trailing-edge.com Trailing Edge Technology WWW: http://www.trailing-edge.com/ 7328 Bradley Blvd Voice: 301-767-5917 Bethesda, MD, USA 20817 Fax: 301-767-5927

"The SCSI<->SMD configuration still eludes me, however. I know they exist (Adaptec ACB-55xx), though I've never seen one. Docs are *really* hard to get. Still looking for the docs for the Emulex MD-23, possibly the best darned SCSI<->ESDI bridge ever made: Handles four drives at up to 24MHz data rate. Smokin'. " They exist.. I'll check if a friend of mine still has any. I have a big pile of adapter docs. The only thing on line currently are for the Xebec 1410 and 1401. Next time I'm at my storage locker, I'll see if I can find the box that has all this stuff. I know that Tony asked me for some old OMTI info a LONG time ago.

4381 (was: Re: Grrrrrr)

This is exactly what I was told by local hobbyists I > approached to find help in saving an IBM 4381 mainframe. Well I replied to the address you set up, but it seemed to have problems, so perhaps my message didn't get through. I worked at IBM when the 4381 was current, and I'd like to see one saved. Not sure how much help I can be at this distance, since I mainly worked on PCs, S/34s and S/36s. I did try and grab any technical info I could find (which was very little since I worked in a marketing unit) and I will try and look things up if I can find anything... > Now I have found at my university floor space, power supply and internet > connection, but almost nobody seems interested in it.

If you think it's worth saving, save it. I think it's worth saving, but I'm not sure there's much I can do to help (which makes it easier for me to declare my support, I suppose). I will e-mail you privately... I tried to save a 4341 around 10 years ago when I was still a student. There wasn't a hope, though...

NCD 15r + monitor 15b

by edick＠idcomm.com

NCD apparently just private-brand-labelled monitors from HITACHI among others. If you take the plastic off, you'll likely find a "real" manufacturer's name and model number. good luck!
