To test a bare Tandy 1000 HX motherboard before hacking together a keyboard I made a boot disk with an ancient version of PC Anywhere on it set up to...

Been there, done that. I sell on eBay, and yes, as a seller you are screwed when dealing with buyers. The "Does not match description" thing is used...

I snaggeda Raidmax case 2+ years ago for precisely 12.09$ after the rebate. It's lite, it's a full mid atx tower. And best of all it's black....

The doc that I have says that the ST-01 can use IRQ 3-5 or none. I used interrupt 0x64 and 0x68 and still the same issue.

Don't really need it but I bought one anyway. The price is right - come on down!

I use those cases for a lot of my projects. They typically list for around $39 but now and then Newegg will bump the price down to $19. I snapped up...

I have a nicely-recapped (circa 2017) 1.8A DataPower-made Lisa PSU on my bench --- the ungrateful poodle is crowbarring for some reason. Lisas give...

Also curious if your CPU is by chance known to be good, ie: tested in a known good working board??

Does the ST01 even need an IRQ under DOS? Seagate's dox say no. If you don't use DHCP, can you still ping using naked IP addresses? I had to...

I think the original tantalum capacitors were 10uf ... maybe you don't have enough capacitance to keep things smooth? Also, I don't think you need...

I'm always open to improvements. Lord knows, I've been down the confusion path many times. Generally that takes a little to come back from, Thanks,...

Yes. Way back on the job days we used PC Anywhere with Banyan Vines. Pretty good stuff for the mid to late 90's.

this is really interesting that the tandy-sound-device get's it's patches. For me as a tandy1000 owner I still think about, why e.g epyx did not...

Gold box games, Zeliard, Ultima IV/V, Bard's Tale, Battletech, Castles, Defender of the crown, Lemmings?

Ok, so after some testing, it seems that it's mTCP's dhcp that hangs there, reseau is a batch that starts the packet and then it lunches dhcp. That...

I would wait for BUSY=0 and /ACK=1 (as you are doing at the moment). Next, send the desired data byte out and wait for 0.5 us (data setup time). ...

I waited for ACK because the interface wave form that the manual showed (with very little explanation) seemed to need it. Maybe checking the ACK is...

From what I understand, Turbo C 2.01 only supports inline assembly through the use of __emit__. I'll dig through the PDF of the manual to see if...

Thanks Al. I will have a look. Hopefully, that will save some time and hassle! Dave

Great, sounds like it working now - the missing piece being the CR/LF. Your code looked alright to me, you are waiting for "not busy". I also was...

Doesn't TCC have an inline assembly feature (sorry, I'm a MSC user)? It should be possible to include this in your code and automatically handle the...

Easy--it was merely to demonstrate how display data can be sent over a printer port--and what to expect. (not a lot). RPi notwithstanding.

I opted for the big Dell heat-pipe passive unit. If it gets too warm, I can add a fan. I've got room--it's a 4U case. In the meanwhile, I'll...

The best air coolers to exist for S478 are these: https://www.alphanovatech.com/en/cat_cpuhse.html#so478 I own a few of them, and they look to...

Yes, the CR causes the printer to print the outputted characters. Although, the printer will not actually do a carriage return. The print head stays...

Enjoy that while programs still being developed continue to work on old releases. Current releases of browsers are the worst for abandoning old...

Nice! Congratulations. Scott

The COPS was one of the IC's I removed for the rebuild but recycled. Two traces had to be repaired and a new socket was installed along with a pin...
