But the higher clockrates are a nice thing - and maybe the z180 for 3.0 style bankswitching. BTW: LDOS - I have a Modell III with external HD - hasn't there been an LDOS to boot from ?

What I want to point out is that the price of a OS isn't just the package you buy at a shop. It's about the time you spend in installing and trying and reconfiguration etc. So, to come back on topic, the best for a TRS-80 emulator is still DOS. Install it, or even boot >from a Disk. You could even put the emulator and DOS and some TRS-Apps on one 1.44 bootdisk. And best of all - Disk access will be Disk access. Gruss H. -- Ich denke, also bin ich, also gut HRK

Its funny, I read through the list, crossing my fingers and hoping for a PDP-8 core stack, and 90% of it is PC junk. Then I kind of laughed because of course that stuff will probably be "collectable" for my daughter. Assuming she decides to collect computers. Although if history is any measure then she'll probably collect Pentium II machines since that will be the "hot" machine that she can't afford (stuck with a measly 75Mhz P5 :-) Another factiod registered which is PC collecting is going to be *much* more of an art than say mini-computer collecting is because the technology is changing soooo quickly. In case you haven't noticed there is a certain temporal component in the PC compatible space where the hardware, and more importantly the software, are tied together at their release dates. "Visual BASIC, Win 3.1, Borland C++, 486/66" they make a set. Use this stuff on a Pentium and it won't use half the features, use it on a 386 and it won't run acceptably. And how "long" was the 486 PC window? Perhaps 3-5 years? Compare that with the utter contempt with which people treat 486 motherboards (3 for $5.00 at Weird Stuff Warehouse) and you realize that these things are headed for landfill big time. Along about 2010 or 2015 and trying to put together a representative 486 system from the "early 90's" is going to be damn near impossible. Look at the PDP-8's which spanned 15 years of production and are now pretty difficult to get hold of. I don't know if I should laugh or buy an old Dell 486 box and wrap it up in plastic and dessicant and save it for 20 years. --Chuck

TRS-80 emulators

by roblwill＠usaor.net

I'm searching for a TRS-80 emulator for the Model III. I need it to be able to use disk images (such as LDOS), and boot from them. ThAnX, -- -Jason (roblwill(a)usaor.net) ICQ#-1730318 PS>> The only reason that I need the emulator is to make LDOS, and a few other programs for the Model III - not to imitate having an actual III :^)

Linux on-track topic (was RE: TRS-80 emulators)

Sounds like they have buying power greater than Wal-Mart's to offer such pricing. Either that, or they have exclusive rights to manufacturer or publisher overruns or defects.

PDP-11/70 rescued!

by CLASSICCMP＠trailing-edge.com

>While I don't regret rescuing this stuff, I have no clue how long it will be >until I could ever power this stuff on. The Hut has its own 60 Amp feed >seperate from the house, but 110/220, no three-phase power. I suppose I >could purchase/rig-up a 220V<->3Ph mechanical converter, You don't need three-phase for the equipment you got - if you look at the DEC power controllers, they just split out the three phase into three 120VAC circuits which power the individual boxes. Especially as you have MOS instead of core memory, 30 Amps will be plenty for a CPU, memory, and a couple of Fuji Eagles. Some big Massbus disks (and their Memorex and CDC mechanical equivalents) do need three-phase for the drive motor, but I didn't see these in your list. >P.S. ISTR that PDP-11/70's and VAX-11/750's use the same hex-height 39-bit >ECC memory boards. Is this true? Assuming you have the DEC MK11 memory boxes, yes this is true. There are also third-party memory boards available for 11/70's; my favorite are the board sets that pop into the 11/70's backplane and give you 4 Megs of cache memory, so there's no need for memory boxes! -- Tim Shoppa Email: shoppa(a)trailing-edge.com Trailing Edge Technology Voice: 301-767-5917 7328 Bradley Blvd Fax: 301-767-5927 Bethesda, MD, USA 20817

Booklovers: Danger!

by Philip.Belben＠PowerTech.co.uk

Rax (Sorry, can't remember your real name) wanted to know, and it seems I kept the original message. Philip. ---------------------- Forwarded by Philip Belben/PTech/PowerGen on 23/10/98 13:10 --------------------------- classiccmp(a)u.washington.edu on 06/09/98 06:29:19 To: classiccmp(a)u.washington.edu cc: (bcc: Philip Belben) Subject: Booklovers: Danger! Maybe I shouldn't post this.... O wot'th'ell, here goes. I have discovered recently a very dangerous on-line book service, which, in my *very* humble opinion, just beats the bloody tar out of the 'major' ones.. (Amazon, Barnes, etc). Some of you Listmembers may already be aware of these folks.. if not, the URL is; www.abebooks.com I'm *definitely* in Big $$$ Trouble. I have a very large library, around 10K volumes, journals, periodicals, papers... collected over many years. A lot of it is old, wierd, rare, fringe-science, technology, engineering, computing, etc. Now I find ABE (American Book Exchange) and they've got titles I've been searching for for *ages*... including a book I read in 4th Grade and never heard of since... oh dear: most of the booksellers on ABE take credit cards... damn, damn, damn...! I've already found over $1K of stuff I must have.. NOW! Anyway, I hereby disclaim and hold myself inurred and harmless >from anyone who goes bankrupt because I turned them on to ABE. Just try searching with Van Nostrand or Wiley or Howard Sams entered in the 'Publisher' slot... or pdp-11 in the 'keywords' section.... I'm in **trouble** ! Cheers ;} John
