:-) Thanks, they look useful. This is an old Admiral unit (good ol' 70's styling, and dreadful internal build quality!) and things are hampered by the fact that they seemed to re-use the model number for a later turntable, making searches difficult. Because the drive pulley is crowned I can't use their string method, but I'll be able to get calipers on the pulleys and work out the belt length using their diameters and distance between them. cheers J. ------------------------------ Message: 2 Date: Sat, 1 Jun 2013 18:14:22 +0100 From: Liam Proven <lproven at gmail.com> To: "General Discussion: On-Topic and Off-Topic Posts" <cctalk at classiccmp.org> Subject: Re: MSBBC - Re: Next box with 1991 web page(s) password protected Message-ID: <CAMTenCEQ8NLotH1MAhzHYmVx=LBTYdzZp0N8piMOv4m_rUYP9Q at mail.gmail.com> Content-Type: text/plain; charset=windows-1252 On 25 May 2013 02:48, Toby Thain <toby at telegraphics.com.au> wrote: > On 24/05/13 9:18 PM, Liam Proven wrote: >> >> On 25 May 2013 02:09, Toby Thain<toby at telegraphics.com.au> wrote: >>> >>> The BBC has been thoroughly infiltrated by ex-Microsoft >>> executives, in a very quiet takeover that few Britons have apparently

We already cleared that up in our book "Atari Inc. - Business Is Fun" released last fall, going by direct interviews and actual internal documents. There were never thousands of ET games buried in Alamorgodo, that's a myth that sprung up later and was also never once mentioned by the actual press articles of the time. The dump there was simply a clearing out of Atari's Texas manufacturing plant as it transitioned to automated production methods and a focus on personal computer manufacturing. It had previously been one of the main plants for manufacturing of game cartridges and other hardware, and game manufacturing was being moved overseas to China. As part of the transition the unused cartridge stock of a group of titles (not just E.T.), console parts and computer parts were all dumped there in New Mexico. It was covered in detail by the Alamogordo press at the time as well, and is just such a non-mystery that I'm surprised by all this.

Only this evening I realized, based on your remark on the extra serial port, that channel A is used for both host (HX-20) and 2nd TF-20 and channel B is not used. So connecting my TTL-to-USB to the TXDB and RXDB and boot the TF-20: alas no output or any reaction to Enter, Esc or

By now I know the boot ROM does initialize channel B, but does not write to it. Apparantly TFDos doesn't either. Fred Jan P.S.

What you are looking for is NetBSD. \begin{troll} NetBSD is the reference implementation of The Unix Paradigm. Linux used to be a free Unix for Unix enthusiasts.

In particular, if you want 386 support, you'll be stuck with older versions.

Meh, I think not. I'm trying to cut down on the number of different platforms I have to maintain, not add another. ippool also wouldn't really be a suitable replacement for the way I use ipset, and the idea of trying to use pf in place of ebtables and iptables for bridge-mode firewalling is very unappealing. In fact, if I had to switch to something else, I'd probably go with OpenBSD (which I already use for other stuff) over NetBSD given OpenBSD's hardware support. I plan to stick with Linux for most embedded applications, but the widespread assumption by many userspace "developers" that everyone has 4GB or 8GB of ram and a 2TB hard drive isn't helping anyone except help hardware companies sell newer gear year after year. Right now there seems to be a gap in the market for a Linux distribution tailored for small/embedded systems which is also easy to maintain/update with a halfway decent package management system. I have nothing against pkgsrc, Ports, etc, but when you are dealing with lots of different systems, and especially those with limited CPU/memory/storage, compiling everything from scratch (as with Gentoo)

I have a few machines too small to self-host; those, I simply don't run a full-fledged OS on. Perhaps this stance simply reflects a gap in my computer collection, the sort of thing for which 256K or 512K of RAM is a reasonable memory load - I don't really have anything between the really tiny machines with the likes of 256 bytes of RAM and 8K of flash and full-blown machines with 16 or 32 megs of RAM and at least a few gigs of disk. /~\ The ASCII Mouse \ / Ribbon Campaign X Against HTML mouse at rodents-montreal.org / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B ------------------------------ Message: 27 Date: Sun, 2 Jun 2013 12:42:47 +0200 From: Holm Tiffe <holm at freibergnet.de> To: "General Discussion: On-Topic and Off-Topic Posts" <cctalk at classiccmp.org> Subject: Re: pdp11/93 mod Message-ID: <20130602104246.GA51212 at beast.freibergnet.de> Content-Type: text/plain; charset=iso-8859-1 allison wrote: > On 05/30/2013 03:09 AM, Holm Tiffe wrote: > >Roe Peterson wrote: > > > >>Does anyone have information regarding modifying a pdp11/93 cpu to > >>run at 20Mhz?

Yes. In my case I've changed the older J11 to one of the last available revisions (-09?) to be at least sure that it meets the

I don't had another FPU Chip so the FPU and the Gate Arrays are the 15Mhz Versions. Tested the entire Machine with all available Test Programms on xxdp to be sore the entire system works as expected...no
