The smallest of those four high-end AS/400 models expected from IBM this year that we told you about last week (CI No 1,117) is tipped to appear tomorrow. The AS/400 Model 70 is expected to offer 25% to 30% more power than the Model 60, mainly by virtue of more main memory and more disk capacity than the 60. Problems that System 36 users have faced when trying to upgrade to the Models 10 and 20 – many have found that at best they got no improvement in performance when running their 36 workload on the baby AS/400s – are also expected to be addressed with new versions of the B10 and B20 offering 20% to 30% better performance, again as a result of better memory and disk. And to address the fact that IBM warns users not to skimp on memory (CI No 1,118), the company is expected to cut AS/400 memory prices. And the company is also tipped to announce that interface to the 3422 tape drive, for ships around mid-year.
