POK had hard time adjusting to the rules, monthly charge had to cover original development as well as ongoing development and support. unbundling posts http://www.garlic.com/~lynn/submain.html#unbundle JES2 NJE couldn't come up with business case ... at any price, market was somewhat price sensitive, as they raised the (forecasted) product price (to try and make up the shortfall), the number of (forecasted) customers dropped. What they eventually hit on was announcing JES2 NJE & VM370 VNET as "joint" products ... where the revenue from VNET was used to make up the NJE shortfall. hasp, jes, nje, etc posts http://www.garlic.com/~lynn/submain.html#hasp JES2 had tried $300/month, $600/month, & $1200/month for NJE ... but forecasted customers were dropping faster than the price was going up. VNET easily met its business case at $30/month ... they announced joint product at $600/month (with effectively nearly all the money going to NJE). ISPF had similar problem coming up with business case ... but by the early 80s, they had relaxed the rules so the products just had to be in the same organization. They moved vm370 performance products into the same business unit as ISPF ... reducing the staff to three people ... and used the VM370 products revenue to underwrite the cost of the 200 people in the ISPF group. https://en.wikipedia.org/wiki/ISPF some misc. recent posts mentioning ISPF: http://www.garlic.com/~lynn/2017c.html#2 ISPF (was Fujitsu Mainframe Vs IBM mainframe) http://www.garlic.com/~lynn/2017c.html#82 Great mainframe history(?) http://www.garlic.com/~lynn/2017e.html#25 [CM] What was your first home computer? http://www.garlic.com/~lynn/2017g.html#34 Programmers Who Use Spaces Paid More http://www.garlic.com/~lynn/2017i.html#23 progress in e-mail, such as AOL http://www.garlic.com/~lynn/2018d.html#48 IPCS, DUMPRX, 3092, EREP more (editor) drift, trying to promote RED which had quite a bit of internal use and maturity at the time Endicott decided to develop XEDIT. Endicott eventually responded it was the RED author's fault that RED was so much better than XEDIT, and therefor it should be RED author's responsibility to bring XEDIT up to RED level. http://www.garlic.com/~lynn/2006u.html#email790606 in this (long winded) post along with other old RED/XEDIT email from the period (and other subjects) http://www.garlic.com/~lynn/2006u.html#26 -- virtualization experience starting Jan1968, online at home since Mar1970
