Hello everyone! Is there such a thing as a Mac emulator for a PC? I'd like to download some Mac stuff from the internet, but the only computer that has internet access is a PC. Any suggestions (besides buying one of those Mac/PC programs)?

Most early "home computers" do have the functionality of a debugger in ROM - they just take decimal numbers, not Hex/Octal, and require you to type PEEK and POKE :-). Tim.

I know about that. A ROM-based debugger would be helpful if I don't have a bootable system. > >On Sun, 1 Nov 1998, Max Eskin wrote: > >> It's too bad most micros don't have a debugger in ROM.

< It's too bad most micros don't have a debugger in ROM. Except for < computers made by Apple, I don't know of any. I especially wish the < PC had a ROM debugger. It would really help me feel like I'm using a < worthwhile machine. Shows what you don't know. Non exhaustive list of micros with debug roms: PDP-11/03, 11/23, 11/73, 11/83, 11/84 (most all the non front pannel 11s) SC/MP IMSAI IMP-48 Kim-1 SYM-1 AMI EV68 series Motorola 6800D1 and D2 intel SDK-80/85/88 SWTP 6800 ALTAIR-8800b (the front pannel is in a 1702 prom!) Godbout 8080/front pannel replacement (octal keypad!) Netronics Exploror 8085 CCS 2200 series s100 crate Heath H8 Micromint SB180 (z180) Intel MDS-800 Intel MCS-8 (8008) MicroVAX series including VS2000, 3100, 4000 and others. I am very certain I've left a truckload of them off. Also if the PC had rom basic there are instruction in basic that allow access to memory, IO and machine language subroutines. Allison

ATMs

by maxeskin＠hotmail.com

Actually, my father asked me, which got me thinking. You know, here in Boston, we had text terminal ATMs until about a year ago, when they were replaced by touch-screen graphical ATMs. I don't like them too much just because of the lurid colors. But anyway, I was just curious if they used a microprocessor, microcontroller, or something else... >> Has anyone here had any experience with ATMs? >> What sort of specs might an ATM have?

Repair strategy (was Re: eBay strikes again...)

by maxeskin＠hotmail.com

Because while VCRs are not considered modular by the general public, computers are. This means that while you can't tell someone that their VCR's motherboard is fried, you can say that about a computer. A repairshop trick to get more money, really. Companies help out a lot too. I'm sure schematics for a NSX Penitum-II 933 Turbo motherboard are a lot harder to find than those for a JVS VCR. And that's another reason why noone bothers to fix motherboards, because while a VCR has certain standard components, a motherboard can have damn near anything on it. It's also interesting how while a power supply is often the easiest component to diagnose and repair, it is always treated like a module, and I doubt many techs have been curious enough to open a PSU. I read in a book once that opening a PSU will cause damage to a special layer that prevents interference from the PSU to the motherboard. I haven't been able to substantiate this... >Actually, in the UK, it's _very_ uncommon to buy complete PCBs for TVs or >VCRs. Buying individual components is a lot more common. And custom chips >should be available while the device is in production, but good luck >finding them in 10 years time :-(. > >I am not sure why 'repairing' computers is done by module replacement >while TVs/VCRs are fixed to component level.

Week end acquisitions

by fauradon＠pclink.com

Hi all, Pretty good finds at the Minnesota Hamfest yesterday. 2 Gridpads Complete (only one set of manual) Anybody has software for those? The Voice, Odyssey 2 Spech and sound effects module Others that are not 10 years old but I'll brag about them anyway: 75 MHz pentium laptop ($20 working) Epson ActionLaser 1500 ($25 working) set of SCM ethernet cards ($2 each Unknown condition) Tere was a few other Grid computers, laptops of all sorts (zenith, toshiba, ps/2 70 ...), and a lot more but my budget was very limited this time so I pcked up the one I wanted the most.

A record?

So am I. I'd have to concede that as being an act of considerable fortitude. I thought I did well moving a Vax 8530/6310 cluster, complete with 2 HSC50's, TA78/TU78 and about 15 RA8x and some RA7x drives from a warehouse to my parents house, then getting it up a narrow gap into a vacant granny flat. Over gravel. But we did have a forklift load it on the vehicle for us. I think the PDP effort beats that one. The TA78/TU78 was the hardest, and the heaviest.. It took six of us to move it all. (Called in a few favours, and a mate with a ute, uh, pickup in us-speak) This doesn't include the several large station wagon loads of 1/2" r-r tape and the docs for VAX-VMS 5.5. For those not acquainted with VMS, the manuals are loose leaf A4 Binders, and there are close to 40 of them. It's normally shipped on a pallet, and referred to by users as the "great grey wall" after the colour of the ring binders. (Some earlier versions were other colours, orange I think, but they weren't quite as big either.) Cheers Geoff Computer Room Internet Cafe Port Pirie South Australia. netcafe(a)pirie.mtx.net.au

Didn't impress me in 40c+ temps. I still have this system. The 6310 (now a 6320) and 1 HSC50 + Star Coupler & the SA550 with it's 8 RA7x (3 72's & 5 70's) are the WWW, FTP and Email site for the school I work at. When it eventually retires, (again!) it's coming here, but that won't be for a few years yet. The 8530 and its CI adapter cabinet, and the TA78/TU78 are used as a room divider at the internet cafe. The 8530 console (DEC Pro380 alias a PDP-11) is sitting on top of it. It lacks only the console cable to make it a goer. The 78's need a couple of new power supplies, but were working til the psu's failed. 1 HSC50 and a cabinet with 3 x RA81's serves as the counter, with a side panel as a desktop. Makes interesting decor for an internet cafe. Mind you it will be a lot more interesting once I get it all working again.

As I use Teledisk for commerce, I don't have any problems with the $150 fee. I agree, it is a shame that the shareware version can no longer be registered for a small fee, especially because large quantities of freely distributable software is out there in Teledisk-image format (for example, all the POS-related RX50's for DEC Pro's are archived at Uppsula in teledisk format.) >Anybody know of any reasonable alternatives, for those of us that >are hampered by rules against theft? Sydex does have a product which fills many of the same needs that Teledisk does, and this is CopyQM. It supports 3.5", 5.25", and 8" floppies and even has some features that Teledisk didn't have. I don't have as much experience with it as I do with Teledisk, but CopyQM does have the advantage that single-user licenses are available for only US$25. -- 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
