Apollo DN 4500 looking to be saved from computer recycler

It's located near Rochester, NY. Information below. Reply to original sender.

Macur <amacur(a)frontiernet.net> Subject: RE: Apollo DN 4500 looking to be saved from computer recycler I have a vintage Apollo DN4500 including 19" monitor looking for a home I also have all the HP/Apollo docs & software (although I doubt the DC600A tapes would be readable) I also have lots of DC600A tapes but my guess is after 10+ years the media would have deteriorated. Its in Webster (Rochester) NY. When I moved from Syracuse to St Louis in 1993 I hooked it up and it booted to the Apollo Domain/OS prompt. I didn't bother to unpack it when I moved from St Louis to Rochester. -- Sellam Ismail Vintage Computer Festival ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintage.org * Old computing resources for business and academia at www.VintageTech.com *

amstrad pcw available

by classiccmp.org＠irrelevant.fsnet.co.uk

Hi.. is an Amstrad PCW (8512 I think) c/w printer of interest to anybody. From memory, it's a CP/M machine, but uses stupid little 3" discs (not 3.5") and originally came with a boot-up-into-wordprocessor disc... It's currently in my neigbours front yard waiting for the bin men, but I've a mind to rescue it. Apparently it works fine, just needs a new fuse. It's in Salford, England, btw .. Rob.

>Besides, at modem speeds, who WANTS to retrieve a 100K message that only >has a paragraph of new content? Could be worse... this comes to mind only because as I read your message, I noticed a new email coming down from one guy that I want to strangle. I am on a mailing list for state surplus property so my Fire Deparment knows when good stuff comes in. The guy that sends out the notices keeps taking digital pics of the stuff, and importing them into MS Word documents before sending them as attachments. So he takes what would be a 50k JPEG, and turns it into a 2.5 MB word doc... just so I can take a look at whatever he is hocking that day (today it was a GMC dump truck). Even on DSL, downloading a 2.5 MB file to look at one picture is annoying! -chris <http://www.mythtech.net>

BBC Micro - assemblers - info needed

The way Acorn did that with things like the Master 128 Welcome Disc was to make all the directory entries (on track 0) point to tracks between 5 and 9, and 20 and 39. Track 20 on a 48-tpi drive is where track 40 would be on a 96-tpi drive: 96tpi 0 5 9 19 20 39 40 59 60 79 | | | | | | | D |X| |XXXXXXXXX| | | |__|_|____|_________|_________|_________| | | | | | | D |xxxx| |xxxxxxxxx|xxxxxxxxx| | | | | | | 48tpi 0 4 5 9 10 19 20 29 30 39 So you need to format parts of the disk as if they're 40-track and parts as if they're 80-track. Start by formatting the disk normally, at the density-of-your-choice. Next, write some dummy files that will occupy exactly tracks 0 (less the directory area) to 4, 5 to 9, and 9 to 19, and then delete the dummy that is in the space 9 to 19. You only need to do this for one density, thankfully, as the object is just to get the right placeholders in the space map. Then write the real data. Switch densities, format the tracks that need to be the alternate density (Disc Doctor can do this), and write the real files again. You may need to do the second set of writes with raw disk access, as IIRC ADFS will "overwrite" a file by writing a new version andf then deleting the old one -- which is not what you want because it will use the wrong space! -- Pete Peter Turnbull Network Manager University of York

>Before we got DSL at work (we're about 17K feet from the CO) we had to get by >with a Dialup. Good old PacBell charged us about a penny a minute... DSL @ >$99.00 a month is actually cheaper... We actually has a similar thing here... I had been trying to get DSL put into the budget for months, and accounting kept saying no. Despite all the added benifits it would bring us, they didn't want the $250 a month price tag that I was proposing (this was early DSL, before you could get it dirt cheap, I was one of the first in my area to get it). So I was smart. I pulled out the last few months phone bills to show the cost we were paying to have our "unlimited" dialup line connected all day. It was connected to the network, and we were running a mail server, so the only time it hung up was after 11pm, and then it went to connecting once an hour to update the mail server, until 8am when it came back up full time again. Showing them three months of $450 line charges got my $250 a month DSL put onto the budget with no further complaints. -chris <http://www.mythtech.net>

>Pay by the minute for connection time? You're getting screwed. Maybe they are, but from what I gather, that is not unusual outside the USA. Even here in the USA, if you are on a dialup connection, and calling from a business... guess what, you are probably paying by the minute. Most business lines in the USA are billed per minute of connect time (or worse, by the "message unit"). -chris <http://www.mythtech.net>

Toshiba laptop wanted (previously?)

by jwest＠classiccmp.org

I had posted a while back about wanting a Toshiba 3100 laptop.... I think someone replied with one I could have, but I can't find that email anywhere. Long and short of it is I need something along the lines of a 286 or so, that is small enough to fit easily on my electronics bench, and has one ISA slot, preferrably two. I was thinking the Toshiba 3100 was pretty close to this. Can the original person who responded please get back to me, or does someone else have something close? I'm wanting to put an HP-IB card in the unit to interface with my test gear, and possibly a wireless card or at least an ethernet port (I could get the ethernet port with a zircom parallel port adapter that I have)... Thanks! Jay West --- [This E-mail scanned for viruses by Declude Virus]

PET 2001 Oddity 6550 Unobtainiums MOS TECHNOLOGY

by kandres＠epssecurity.com

Eric, Yes, you are correct. My fault. I've always mixed up MOSTEK and MOS Technology. It seems I remember that the MOS Technology folks left Motorola because of the way the 6800 was progressing, but that could be a faintly remembered rumor also. MOS Technology was responsible for the 6550 ram. I seem to remember having a book from 82 or 83 from MOS Technology somewhere. Kev --- Outgoing mail is certified Virus Free.
