9816,9826,9836,9000-300 Message #1 Posted by Mel Heillman on 15 Nov 1999, 11:11 p.m. These machines are a few of an entire line of 'things' made by HP that fall into a gap between computers and calculators. Because of the power of these machines, and the low cost on the used market, there must be on the Internet, somewhere, a vast storehouse of knowledge. Does anybody know of any WEB sites that include info on these machines?

Re: 9816,9826,9836,9000-300 Message #3 Posted by Joe on 18 Nov 1999, 8:12 a.m., in response to message #1 by Mel Heillman The HP 9000 200 series machines were the replacements for the HP 9800 series calculators (9810, 9820, 9830, 9815, 9825, 9835 and 9845). The 9000 200 series were later replaced by the 9000 300 series. One of the odd things about the 9000 200s were that most of them also had a 98xx designation. 9000 236 = 9826, 9000 216 = 9816, 9000 236 = 9836, 9000 220 = 9920 (not a typo). The 9000 200 series were a major engineering change for HP, they no longer used custom CPUs but instead used an off the shelf 8 MHz Motorola 68000. The U machines used a 68010 at 12.5 HMz. The 9836 C was a color version of the regular 9836. You could also get a 9836 CU. Another major change was that the 9000 200 machines did not have a built-in langauage, instead they used disk-based langauages. HPL, BASIC and Pascal were available. It's interesting to note that you could have all three on one disk and tell the machine which one to load at boot up. In fact, you could have multiple versions on each one on the same disk and pick the version to be loaded. You could get HPL, BASIC or Pascal in ROM on a plug in card but they're not very common. I've seen a few BASIC cards but I've never seen HPL or Pascal on a card. BTW HPL is what HP called the arithmatic language that the 9825 used. The 9825 was a VERY popular instrument controller and the 9826 was it's designated replacement. That was the only specificly designated repalcement in that series despite the similarity in model numbers. I have some pictures and info about the 9000 200 series and the 9800 series machines posted at "http://www.intellistar.net/~rigdonj/hpdcalc.htm". It hasn't been updated in a while. If you have any more questions, just ask. Joe
