>Can somebody give me a hint as to how to get into this thing to install >more ram? The outlets are along one side in a vertical configuration.
There are two RAM slots. The first may take a double-sided (two bank) stick, whereas the second can take a single-sided (one bank) stick only. This significantly reduces the number of possible combinations. Eight megs, minimum, is required for 600 dpi operation. The original four meg configuration gives you 300 dpi operation with loads of cache space; the optional 6 meg configuration gives you 600 dpi and some cache space ... not a lot. I believe 24 MB is the maximum, using one 16 MB two-sided and one 8 MB single-sided stick (an 8 MB two-sided stick was standard on Pro 630s which had the PhotoGrade option installed at the factory, and, obviously, that stick may not be moved to the second slot should one later do a RAM upgrade on the Pro 630) but do check Guru for the several supported configurations. >Also, where would a hard drive go? A third-party bracket was sold for several months after the Pro 630 was introduced. Apple never made a bracket, nor would it support problem with internal hard drives on the Pro 630. The main hard drive manufacturer then was Conner, and the 40 MB version, usually found in PB140s, would not reliably work in a Pro 630. The 20 and 80 MB Conners, and the 80 and 160 MB Quantums were OK. (The IBM drives were not introduced into PBs until after the Pro 630 had been replaced by the similar 16/600. The Japanese version of the 16/600, the 16/600-J, had an IBM drive as standard equipment). While the drive mounts on the I/O board on the 16/600 and 16/600-J (but different ROMs in each), a special bracket is required on the Pro 630. And, as I stated, this bracket was discontinued after several months. Too many customers were installing the prohibited Conner 40 MB drives, and the bracket manufacturer decided to go belly-up rather than field all the criticism of its product, which was actually traceable to a defect in Apple's Pro 630 ROM. Well, there was a defect in the bracket itself ... it would not mount in the Pro 630 chassis and also allow the Pro 630's cover to be reinstalled ... not without super-gluing a pair of nylon washers as stand-offs on one side of the bracket. This was traceable to a manufacturing defect, where the two PEM nuts were installed on the wrong side of the bracket. So, what with all the support problems on account of the Conner 40 MB drives, and the basic defect in the bracket manufacture, it is not surprising that the product failed. The concept of an internal hard drive was successfully handled in the 16/600 by the simple expedient of not requiring a bracket at all, and by Apple supplying a hard drive which had been qualified on the product. The Pro 630 bracket is a complicated nightmare to manufacture, requiring many punching and forming operations. Surplus brackets from this failed product never showed up in the "usual suspect" Silicon Valley surplus outlets (Halted, Haltek, Weird Stuff, etcetera) and I can only presume that the remaining inventory and the manufacturing tooling was scrapped. I have one Pro 630 with a working hard drive kit, and one 16/600 with a factory hard drive kit. Although I own an Adobe Systems "Font Folio" (a 105 MB hard drive in a Taiwan case, attractively labeled with the Adobe Systems logo, and loaded with all Adobe fonts up to a certain number in the high 100s, and priced at about $10,000), it is far easier to load the fonts onto the internal hard drive. My Pro/630 has a 20 MB Conner (its 80 MB Conner and 160 MB Quantum each failed after about a month of use); my 16/600 has its original 500 MB IBM. A 160 MB drive is more than adequate, and even true Adobe PostScript RIPs which came with hard drives because they were "banding" type devices (LaserWriters are "frame" type devices and do not require hard drives) came with 20 MB (300 dpi) or 80 MB (1540 and 2540 dpi) drives. It was assumed with an Adobe RIP (Redstone, Atlas, etcetera) that the fonts would be in a Font Folio hard drive (external), although this was not a requirement of the mass-marketed RIPs, which were embedded in several LaserWriter and QMS models. (The Linotronic 200P and 300P were never mass marketed. In fact you couldn't even get Linotype/Hell to give you a price quote on one of their machines ... they wanted to sell you the machine only with a service contract, for nearly $100,000 plus several thou per year for on-call service). More than you probably wanted to know, but there you have it. -- 1st-PowerMacs is sponsored by <http://lowendmac.com/> and...
