Re: Flex Disc options for the HP 9825

I wonder if the crowbars might have been a later revision of of the power supply. After the accident with my 9835A I had to completely rebuild the +12V regulator both the 723 and the pass transistor as well as a few passive components. I did not see any evidence of crowbars, and the power

RE: Flex Disc options for the HP 9825

Marc, Building a crowbar is easy, just take a Zener a little higher than the psu voltage eg 5.2V for 5V rail put a resistor of 1k in series take a Thyristor big enough to take about 150% of the schort current and connect it to the zener through a small resistor. I suppose you can do the math ;)

Intel SDK-85 monitor ROM

Hi List, I've started looking at my SDK-85 after having it on the shelf for years. I know the 8355 mask ROM on it isn't working but I haven't been able to find a suitable replacement. I wired up a temporary solution with a 2716 EPROM only to find the ROM image and source code aren't available

RE: Flex Disc options for the HP 9825

For what it's worth a small warning about the HP 9825 series computers. The power supply doesn't have a crowbar(over voltage protection), so a transistor failure in the Psu can be catastrophic. On the other hand the two 9835's I have, which uses the same form factor and almost the same power

Re: Intel SDK-85 monitor ROM

I sent him a private email with a binary dump of the 8355 from my SDK-85. It shouldn't be hard to find an Intel 8755 EPROM version of the 8355 ROM version. Then you just need to find someone to program it if you can't program it yourself. I can program 8755 parts, but postage to Australia might

Atlanta warehouse

I can see that one day's notice did not do much good. I am sorry, but Atlanta is over 1500 miles from home for me, and I usually do not get much notice. Next time I will try to give at least a week notice. There can be absolutely no viewing on the weekends. That is out of the question for him.

Kermit version compatibility.

Multics 12.6 has a Kermit program; the history log in the source indicate that it written circa 1984 and last modified circa 1990. My local host runs CKermit 9.0, circa 2015. They do not play nice; some Kermit protocol change is causing high packet retry rates, timeouts and sometimes complete

Re: Intel SDK-85 monitor ROM

I'd like a copy of the SDK-85 ROM also. Those using an SDK-85 should be aware that there are at least two different released monitor ROM versions, versions 1.2 and 2.1. The RAM usage of the two is different! I wrote a program based on the manual for one ROM version, and discovered that it
