A while back my HP 2000 Access TimeShare BASIC system went down due to memory problems in the IOP (a 2100S). I thought the problems were in the core boards or the XY drivers, but just yesterday noticed that the main memory controller card (Data Control, 02100-60011) was introducing parity errors into a known good set of cards. So I suspect that many of the 8K core stacks I thought were bad, really werent and it was the data control board all along. So.... I wanted to ask if any of the list members had the following: Either 1) An HP 2100A or 2100S cpu that they would be willing to sell me or 2) An HP 02100-60011 Data Control card that they would be willing to sell me While a data control board is all I really need, I would certainly entertain buying someones 2100 cpu if it's sitting on a shelf as it would be extremely helpfull to have a spare set of the cards that make up the cpu section too. After all, the cpu is pretty much useless without the data control card anyways. Of course, I'd be perfectly willing to trade as well as buy if I have something people are interested in. Thanks in advance if anyone can help! Regards, Jay West
