Now easier for people to get HP2000/Access up (was:

Yep, I agree, that?s how I remember it happening, and in fact we have evidence of this in our possession. The Access Internals documentation 22687-90020 on page 4-39 has a snip of source code for the power fail routines and the very first comment references TSB/G. As for a company (as I recall from Canada) supporting a version called TSB-G, I think this was also the case. I want to say that their version also supported accounts that started with an at sign (ie @000-@999). After the 2000 line was ended the source was made available to existing customers and VARs for the price of $500, as I recall. Not many took advantage of the opportunity, but HP would allow a VAR to put systems together and sell them with the TSB software. I may even have a notice here in an HP users group publication about this. Access and I assume System were the only versions that required IOP micro-code. And the descriptions of the micro-coded instructions are in the above-mentioned document along with the rational for this enhancement. Now a big ?HIP HIP HORAYYYYY? so glad that last version of the micro-code has been found! That is fantastic news! And by the way, the next version of SIMH should run Access without tweaking, at least under windows. ZIPs are still available for people wanting to play with a pre-release package. (Yes Jay, still waiting for you to put up an Access system on classicmp, it runs under SIMH.) FWIW Mike Gemeny

Intellec 4

by JMeyer101＠aol.com

I recently acquired a few older computers. One of the units is a working MCS Intellec 4. Unfortunately, I have no knowledge of how to program this computer or what accessories can be used with it. Can anyone help me out? Thanks, Jeff

Sellam was able to track me down and return them :) I don't think that extremely valuable items should be left unattended( like an Apple 1 ). Also small easily hand carried items are not a good idea to leave in plain sight. It is not that I don't generally trust those that come to such events it is just that in any large group of people, there are always those with psychological problems the are related to snatching things. Often these people are otherwise respectable. I doubt we've yet see anyone come to one of these events with the intention of stealing things. The first rule of people is that most are strange. Each has different motivations. Dwight

Out of >the first batch of ten, 4 are now unreadable or give multiple errors. Hi This would put the per unit failure higher than even floppies. I have floppies that are in the 25 year range and still read correctly ( not used regularly for archiving ). The only large issue I've seen on floppies is those higher quality ones with the liners. The adhesive used to attach the liners tended to bleed through the liners and get on the disk. I do keep things stored in areas that rarely see more than 75F or more than 75% humidity.

True bugs can have most any number of pins, so long as it is an even number. I believe that some like to use them in the bulk sense but just some notes on the proper way to connect the pins can be useful. Dwight

Article on data rot on CD's

by mmcfadden＠cmh.edu

I saw this today on USA today website. I've been scanning 50 year old slides to CD's and I still have my older PDP-11 data backed up as paper listings and now on CD's. The NIST also has a paper on data longevity and storage suggestions for CD's and DVD's. http://www.usatoday.com/tech/news/2004-07-26-longevity_x.htm Mike.

8" floppy project

by trash3＠splab.cas.neu.edu

I've stuck my RX02/RXV21 into my microvax and used it. However, I prefer the DSD880 subsystems, as they have formatting built into the front panel and firmware. I also prefer to run RT-11 to do all the fooling around, not VMS/Unix/RSX/RSTS,etc. If I recall, the DSD box or the SMS/Qualogy boxes used the standard 850/851 drives. I haven't powered up the DSD 440 floppy subsystem I have, but I'll bet that does both/all three densities. I have some OLD 8 inch IBM drives in external boxes. Never opened them. If you want to try one in the project, let me know, you can have one. No idea of the model or if they are single density. I'll pop one open if you want. Joe Heck

Now easier for people to get HP2000/Access up (was: MoreHPmicrocode & loader rom detective work)

by aek＠spies.com

Timesharing Consultants (TSC) sold a version of TSB for a while. I got a couple of hibernate tapes from him, which is probably where the IOP board came from Apparently the systems were called TSC-200 and TSC-300. Mike Gemeny may know more about this.
