Somewhere :-) I was right -- I found it, all 118 lines, including comments, along with a pile of other stuff from David Ahl, such as KING.BAS (same idea, but twice as big).

>I'm sure I've seen a copy on one of the Vax sites somewhere. It's not "a VAX site", but Hammurabi does appear on the Spring 78 RT-11 SIG tape, and this is available by anonymous ftp from ftp://sunsite.unc.edu/pub/academic/computer-science/history/pdp-11/rt/decus… The top looks like: 100 PRINT "YOU ARE THE RULER OF THE ANCIENT KINGDOM OF SUMERIA." 101 PRINT "YOUR PEOPLE CALL YOU 'HAMURABI THE WISE'. YOUR TASK IS" 102 PRINT "TO DEVELOP A STABLE ECONOMY BY THE WISE MANAGEMENT OF" 103 PRINT "YOUR RESOURCES. YOU WILL BE BESET FROM TIME TO TIME" 104 PRINT "BY NATURAL EVENTS. THE ONLY HELP I CAN GIVE YOU IS THE " 105 PRINT "FACT THAT IT TAKES 2 BUSHELS OF GRAIN AS SEED TO PLANT" 106 PRINT "AN ACRE. MAY YOU JUDGE WELL, ALKNOWING HAMURABI." 107 PRINT "***********HAMURABI IS HERE***********" 110 P=95 (...) > I'm fairly > sure I have a copy on one of the hard disks here, too. Somewhere :-) Heck, I've got my set of 4 8" SSSD floppies straight from Creative Computing with "101 Basic Games" and "More Basic Games". It's fun to fire up the IMSAI, load a game, fix the typos (yes, there are typos in many of the MBASIC sources!), and play a game of blackjack, lunar lander, or Hamurabi! -- 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

Intellec 8 -v- Altair 8800

by headcase＠eclipse.co.uk

When collecting vintage/classic computers it would seem to me that the apparently much sort after Altair 8800 is the Model T to the Intellec's R.R. Silver Ghost. At the time - 1974 - I thought the Altair was a very very cheap copy of my very very very expensive Intellec - and I still do! But then I would, wouldn't I? Have I fallen for all the eBay hype or have I've been wrong all these years? Jim Bunting - headcase(a)eclipse.co.uk M.V.

More thoughts on building a Z-80 (64bit!!!)

by allisonp＠world.std.com

< Wire wrap?...hmmm I have problems with that in ohmic losses even the < connections is good, soldering them helped a bit but no dice. Huh? I have 6 cards, s100 protoboards with about 25-40 pieces of mos and TTL on them that I wrapped in 1981 still running. Ohmic losses? What were you doing wrong. Remember #30 is for signals not power! < Have data transfers done with DMA, all memory mapped and irq driven < to knock subCPU as needed to grab data then place it in CPU's lap. < Leave CPU alone for processing. How about that? Those 6 boards built a multi z80 system with DMA and slave processors for things like IO and disks. It helps but the z80 bus is so busy that it's very hard to slip inbetween cycles so you steal cpu cycles by holding it off with BUSRQ/. Z280, z8000 and Z380 use burst mode access to the bus so that other devices can get in and get a few cycles without holding up the cpu. Even with slaves you reach a bottleneck between memory management and overhead to move data around. Still the results with 6mhz z80s were enough to blow away 386/16 class machine for text oriented applications. Allison

PDP-11/70 rescued!

by Innfogra＠aol.com

What third party Unibus disk controllers are you looking for. I may have some non DEC controllers. I also have an HSC50, 5 RA81s, an RA60 and a TU 81+ in Portland Oregon that I am interested in selling. I think I have a couple of Eagles for sale too. I also have a VAX 730 with R80 & RL02 for sale.

Not all micro BASICs support this. > I'm pretty sure Applesoft is onethat does _not_. Hmm shure ? I have to admit that I don't remember (stupid meone). But I think it will . After all Applesoft is jsut another MS-Basic. I'll try as soon as I'm back home. I'll post the result. Gruss H. -- Ich denke, also bin ich, also gut HRK

Be carefull with you bidding, there can be a lot of bulk wiith this stuff. Bid slightly over the scrap price unless you can't live without it. If you can't live without it bid 30% maybe. Watch your quantities. Paxton
