macintosh rom simms

Every Macintosh from the II forward (well, probably not the Classic) was built with a ROM socket. However, the vast majority of them have ROM chips soldered to the board, and the socket is only there for updates which were never deemed worthwhile. Unless you have an incredibly rare Q700, there are ROM chips soldered to the board. They'll have a part number something like 343S0xxx or 341S0xxx and there will probably be four of them (each with its own, probably sequential, number), although there might only be two if they used 16 bit wide chips. I'm not sure if the Q700 is recent enough, but at some point they moved to 44 pin PSOPs for almost all their soldered down ROMs. Symptom of a missing ROM would be that the machine powers up just fine and all the drives spin up, lights come on, but there is no start-up bong and never any video from the monitor output. If the machine fails to power up all-together, then you have a different issue than lack of ROM. If you have a power supply failure, the power supplies from the IIcx, IIci, IIvi, IIvx, Q700, Centris 650, Q650, and PowerMac 7100 will work in the Q700. It was a long-lived power supply model.

The built-in SCSI is unenhanced SCSI. That means that its maximum theoretical performance is 5 MB/s. It's okay, but can seem a trifle slow. The best SCSI NuBus card only goes up to Fast & Wide (20 MB/s theoretical maximum). There are no Ultra-SCSI nor IDE/ATA NuBus cards for the Mac. If the thing has an original hard drive in, you could probably get some speed boost just by installing a more modern SCSI drive with a faster media speed. As slow as the built-in SCSI was in older Macs, the hard drives of the day usually couldn't sling data even that fast. > I still need to track down that goofy ethernet dongle that gives you an > rj-45. The connector is called an AAUI (Apple AUI) so you need an AAUI to UTP transceiver. Of course, if you're hunting on Ebay, there's no telling what the seller will call it. There were also transceivers for thinnet and thicknet, so do not accidentally buy the wrong one. Those things were cheap to free a few years ago. They may have all made their way through the second-hand system to the point where they're not as easy to come by now. If you have a Goodwill Computer Works store in your area, you might check their cable bins. Ours used to be full of the transceivers. > Date: Tue, 10 Mar 2009 15:49:18 -0500 > From: Brian Lanning <brianlanning at gmail.com> > On Tue, Mar 10, 2009 at 3:31 PM, Cameron Kaiser <spectre at floodgap.com> > wrote: >> A Radius card would go nicely in a unit like this, though. > > ok, so I'll start shopping for that. > > I'm having a hard time telling the difference between the video cards. > They all look the same to me although I'm sure some are better than > others. It's been a while since I checked, so my memory may be faulty, but I think that I remember that the built-in video on the Quadra 700 and 900/950 is faster than you're likely to get with a NuBus card. It's primarily a bandwidth issue. Telling the difference in NuBus video cards can be truly dizzying. The four main players were Raster Ops, Radius, SuperMac (not the later Umax owned clone maker), and E-Machines (not the much later PC maker). Around '94 SuperMac bought E-Machines. Not long after that Radius bought SuperMac. When they were being made, the NuBus video cards fell into two categories: consumer and professional. The late model consumer cards are good yeoman-like cards. The professional cards have some great QuickDraw acceleration on board. The fastest Mac NuBus video cards were the Radius Thunder IV GX series and the Villagetronic MacPicasso 340 (not the 320). I think Sonnet also sold the latter under another name. Raster Ops may have had a card in the same class, but I'm just not very familiar with the Raster Ops products. The Thunder IV GX series came in four models, 1152, 1360, 1600 and the Thunder 24/GT. The first three indicate the first number in the highest resolution of the card which supported 24 bit color. The latter, differently named card is just like the 1152, except it lacks the DSP daughter board. The IV GX models were about $3000 when new. The Thunder 24/GT was a bargain at just under $1000. All of these usually command a pretty high price if they come up for sale at all, but they are faster (in some functions) than a PowerMac PDS-based HPV card. They excel at tasks which are amenable to Quickdraw acceleration. They are still limited by NuBus' bandwidth and so are not so good at throwing frames up on the screen in quick succession. The late model consumer level cards include the Radius PrecisionColor Pro 24 series and the E-Machines Futura II series. Each of these contained three or four models which carried different amounts of VRAM. To truly muck things up, there was an earlier card called the Radius PrecisionColor 24 (no Pro) and the Futura (no II). The earlier cards were bigger and slower and less compatible. Again, Raster Ops probably had something too. SuperMac's last professional level card is often recommended by people and it's a good card by all accounts (I haven't tried one). The Futura II SX had a couple of optional daughter boards. One was a DSP coprocesser board, which isn't all that interesting these days. The other was an ethernet daughter board, which isn't especially enhancing in a Q700. The ethernet driver for the daughter board doesn't work with Open Transport and will freeze the machine at boot time if both the driver and Open Transport are loaded. The ethernet daughter board only works with Classic Networking. Okay, that's probably way more detail than you need, but how often do I get to dump this accumulation of now mostly useless knowledge out? Personally, I would just get the VRAM, unless you need support for larger displays for some reasons. Jeff Walther

Soldering to batteries - a word of warning...

by ian_primus＠yahoo.com

Well, I did something mildly stupid recently, and I did it even though I _knew_ the dangers. Some people might not know these dangers (or think about them), so I figured I'd post a word of warning, since this is bound to come up in classic computing. So, I was recently givin a copy of "Mario All Stars" for the Super Nintendo. It played, but the save game feature doesn't work. These cartridges use a battery-backed SRAM chip to store save games. So, my assumption was that the battery was simply dead. Opening the cartridge revealed the problem. The battery (a solder-tab style CR2032) was actually good, but the positive terminal 'tab' had come off. The spot-welds just let go. It must have been poorly made, and then got dropped at some point. I don't have a replacement battery with solder tabs, nor do I have a way to get one quickly. But, this seems simple enough, I'll just solder the tab back on. Now, I've soldered to coin batteries before and never had a problem. The trick is to rough up the surface of the battery so the solder can stick, and work quickly to avoid damaging the battery. Well, this battery wasn't having any of that. The solder simply would not flow. It was then that I thought "I can't heat a lithium battery too much - it might explode!". So I donned my full face mask and got back to work. More attempts to get the solder to stick were failing. I tried piling on more solder, so that the flux might have a chance to get it to flow. It looked like it was just about to stick and.... PFOOOF!! Yes. Lithium batteries _do_ explode when heated too much. The battery exploded sending bits of black crud and molten solder (that never stuck to the battery) everywhere. It suprised the hell out of me, that's for sure. I heard a little *plink* as the top cover of the battery landed behind me. I just stared at the bottom of the battery on the bench for a minute, startled. I took off the face mask and went to get the vacuum cleaner to clean up the mess. After cleaning up the debris and finding the battery tab and the battery cover, I was trying to figure out how to replace this battery - and if I should try soldering to another cell (more quickly, this time). I then looked over at my face mask on the table. It was covered with solder spashes, and quite a lot of it too (remember, I was trying to get the flux to help the solder flow). Had I not been wearing that mask, I would have gotten all sorts of crud in my eyes. I've always worn this mask when drilling, dremeling, using the table saw, and yes, when soldering to batteries. This is the first time one has actually exploded though. Yeah, it was my fault, I heated it too much - I should have known better. But it's easy to get frustrated and forget. But never forget to put on safety equipment when working with stuff like this. Givin the choice, I'd always rather have a piece of impact-resistant polycarbonate between me and flying shards of hot metal. -Ian
