History and Trivia
Concrete IBM AT model.
Announced 1989-09-26 as a new entry level model. This is one of the few PS/2 computers with the classic ISA BUS (instead of MCA) and 30 pin SIMMs (100-150ns - ugh). It had a 10MHz 286 processor and came with either 512kB or 1MB of RAM, which could be upgraded to 4MB on the motherboard, 16MB with an adapter card. The case is the same elegant, one-drive-only as the 55. It cost between $2,965 and $3,865.
The IBM Personal System/2 Model 30 286 (IBM 8530-E21) is a new entry level 80286 version of the Model 30. It combines existing Model 30 function along with improved processor performance, 1.44MB diskette drive capacity and VGA graphics. The Model 30 286 utilizes the Intel 80286 processor and operates at 10MHz with one wait state to system memory. The IBM Personal System/2 Model 30 286 (IBM 8530-E01) is a single diskette drive, without a fixed disk drive, version of the Model 30 286. An optional 3.5-inch 20MB fixed disk drive feature (P/N 27F4969) is available.
One of the weirder aspects of this model is that it does not have a regular PC speaker, but a "beeper". Where this is physically located, I could not find out. It must be very small. Synthesized music sounds really horrible over this beeper, and synthesized speech is barely comprehensible.
The reason for this lies in the ISA BUS. Full length ISA cards are longer than their MCA counterparts, they fill the whole length of the case leaving no space for a speaker.
And it does not have a regular battery either, but a Dallas self-contained CMOS RAM module with integral real-time clock and battery. This feature, however, it shares with all the other models in the same case, as the 55. You can look at this thing on Tavi's page. It's not as bad as it sounds, it costs less than some batteries to replace, and, as with all PS/2 models, no soldering is needed.
