I'm a little surprised to see a list administrator specifically calling out a critical response to an original statement that seemed destined to provoke one; and not including the original post and poster in the admonishment. It may lead one to presume Jay sympathizes with the original

Tandy Technical Reference Manuals

I have several Tandy TRMs that apparently are not yet posted on-line. I just scanned in the 4000 TRM and will upload it to the tvdog archive today. Will take a few weeks to get the rest in. But in the meantime, if there are any requests, I can reshuffle the order: Tandy 2000 Service Manual

Re: TRS-80 Model 12 versus 16B

Jim, I'll have a 16B at VCF-SE this weekend. You take as close a look as you want. It has a single slim 8" drive, an internal 15MB hard disk, and an external 5 MB hard disk. It also has the 68K card stack with 768KB RAM. I don't have a keyboard for it though. I bought a 16 keyboard thinking it

Being a long time Eagle user, I'll chime in too. Most responses from KiCAD advocates miss the mark on the fundamental issue. Sure the features are converging and I have no doubt KiCAD will catch-up. It has already surpassed Eagle in many feature areas. But people who routinely spend dozens of

Not sure if you are aware, but FYI - Malcolm MacLeod with some involvement from Kyle Owen, Jack Rubin, and others ported your code to a ATF1508 CPLD with a minimal test board. I believe the longer term plan was to make a full featured community project from it, but it's stalled a bit atm. You

One caution about isopropanol. I keep a lot of 99% around for post-cleaning electronics assemblies, soldering, etc. I used to use it as a general cleaning and de-greasing agent for most vintage computer things until several plastic and a couple painted surfaces showed changes not in color but

Tandy 5000 MC maybe - though it still needs a power supply rebuild and the infamous missing Reference Disk. A fully expanded 3B2/1000-80 (5 CPU + 3 MPB) that isn't as rare but it is quite fun to play with - and I do often. A few systems that are new in the box, stay in the box climate
