Re: Fluorescent lights (Was: Full immersion emulation)

I bought 4x2 (4', 2 bulb) replacement LED fixtures on Amazon to swap out some of the fluorescent fixtures in my shop. You can get 3 color temperatures (I got 2700k I think). Hard-wired, but an easy install and the light is very bright. $53/per. Rich Sent from my iPhone On Mar 6, 2017, at

Cromemco disk question

All –     I’m trying to test a Cromemco 16FDC controller…long story but it’s part of a QDOS project. I’m looking for recommendations on a 5.25” disk image I could use for testing. The system is simple – 16FDC, CompuPro RAM17 (with $C0 block disabled), and a Z80 card. The 16FDC

Re: RX02 rx-01 heathkit 8 inch drive for H-11 ( lsi11 heath case drive diff?)

Are you referring to having the H-27 drive from Heath? I don't know for sure because I've never seen H27 docs, but the disk capacity is the same as the RX01 (256k) and I think the interface was made deliberately incompatible, likely at the behest of DEC. The version of RT-11 (called HT-11)

Re: PC/AT "power good" problems

Chuck – My wording was probably less than precise, but “never comes out of reset” means that it never POSTs. Nothing on the screen. No cursor. No boot message. No BASIC. Keyboard does reset though (I see the three LEDs blink on, then off). I watched for a good 5 minutes before giving
