That looks like a plain KDF-11 to me (M8186) - no boot ROM on that board. Perhaps it had more boards at one time - that's a pretty lightly-loaded machine. -ethan

SGI Indigo2 feet

by doc＠vaxen.net

I just unearthed several pair of deskside feet for the SGI I^2. I have a couple of teal pairs and a couple of purple pairs. USPS flat-rate is $10.35, so I'll take $16/pair shipped, first come first served. Let me know *off-list* whether you want teal or purple and we'll arrange payment. I'll post here when/if they're all claimed and will ship within 2 days after I receive payment. Doc Shipley

PCjr Telnet BBS Test

Ahh, I see. I will try and pay another visit to it tomorrow via a landline connection. I would do it tonight, but I don't have the time.

Back in December I made a change to the way I measure elapsed time.? The change gave me like a 30% performance improvement because my original code was so bad, and the new code was counting timer ticks which is pretty easy.? When I made the change I changed all of my units of time measurement from 100ths of seconds to milliseconds. Except in the configuration file that defines the timeouts for the BBS. :-) The result is that I'm retransmitting packets if I don't get an acknowledgment in 0.4 seconds, not the 4 seconds that I intended.? Which? explains why your particular modem connection was driving the retransmits so hard.? Most broad-band users don't have that problem. It's not bad enough to stop and restart the BBS, but it definitely is exercising that path in the code pretty hard. Mike

trs80 Model 4 versus Model 4D

by dgriffi＠cs.csubak.edu

I'm wondering if a TRS-80 Model 4 can be converted into a 4D simply by swapping out the floppy drives. Anyone? -- David Griffith dgriffi at cs.csubak.edu A: Because it fouls the order in which people normally read text. Q: Why is top-posting such a bad thing? A: Top-posting.

Tandy PC's

Portable in a sewing type case - think it is a Model 4P. Monitors of three types. Lots of dos and cp/m (I think). And various types of programs and disks and peripherals. I'm being some what vague because it has been a very long time since I used them. The '80s I believe. They all worked then but the drives might need to be hand spun to free them from sitting. I have moved twice and they are packed up. I am in my early 60's of age now and will never get to put a collection room together. I would like to see them go to a worthy cause and be used - not destroyed.

If I die my son will just trash them and I don't wish that to happen. Thank you for your time. Rick

PET Software on ebay

by silent700＠gmail.com

I don't know how much of the PET world is archived and available out there, but someone (not me, don't know him) but this might be a good project for someone willing to read these tapes: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=320386939956

Installing and running other OS than RT11 and XXDP (with TU58 emu) or BSD (with Vtserver)

by spedraja＠ono.com

As I told in a previous message, I was success installing RT11 v5.3 in one ESDI drive managed with one Dilog DQ696 (treated as a DU drive) in one PDP11 where I boot with one copy of this OS managed with TU58EM (TU58 emulator) >from one PC laptop. I shall try in a while to install BSD2.11 with Vtserver, and to start XXDP >from TU58EM. But I should like to ask to ask everybody insterested about this question: Can I install other OS in the PDP11 using these pieces of software (Vtserver and TU58em) ? I was thinking in other versions of Unix previous to BSD2.11, or other OS as RSTS, IAS, RSX or DSM. By the way... Is this one (DSM-11) available in some form ? I know of one copy from one member of this list which was available some years ago but this is lost actually as far as I know. Regards Sergio
