Finally found a good spot to stick this Reddy Kilowatt sticker a friend made 😏⚑️

@tbn97 CoCo2b's (cat 26-3127B)have a 6847T1 VDG that supports true lowercase with a POKE. You can tell 2b's by typing the number zero on the machine. If the 0 has a slash through it then it's a 2b. If it's a hollow zero then it's a normal 2 with the original 6847 chip.

Also 2b's say TANDY on them instead of Radio Shack.

See here for a good summery of all the coco2 models

@wilkie I still have the key to my LASER Turbo XT. irrc the lock disabled the keyboard.

@goosey my first car in high school was a 71 gmc stepside. 3 on the tree 6cyl. I really regret getting rid of that truck.

Well I got a EPROM burner and rigged it work on the 2364 rom I pulled. I see 8 bytes that don't match the ROM images I find on the internet. I put my read image in an emulator and it never boots. The live memory map shows it stuck in a bootloop at about the same rhythm I am seeing on the scope. I think I am on the right path 🀞

@Truck Ya I thought the CoCo1 "chiclet" keyboard was bad. The ZX81 one is next level πŸ˜†

You could always get/make one of these

Well RAM is ruled out. I think I am dealing with a bad ROM. D3 off the ROM seems to have lots of 0's. Also I am told there are HALT instructions in the rom code but the /HALT pin never drops on the Z80. What ever code it is executing sure doesn't seem right. Sockets installed. Ordered a 2364 to 27c64 EPROM adapter from RETRO Innovations. Now to wait for the mailman 😴

@publius Ya thats the plan. The ZX81/TS1000 boards are not the most study things so I want to minimize the amount of times the iron touches it.

Who knew such a little computer could be such a big pain πŸ™„

@scearley Ya. I actually have a real fax machine at my house. I work from home so the fax machine saves me from having to go to the office to drop off paperwork.

Also if someone faxes to my SDF sip extension my pbx detects the tones and routes it to the fax machine. 🀣

@guizzy Neat. To bad mastodon doesn't seem to have a ssh interface like Pleroma. My color computer 1 may still work (1980) but Lynx would be unusable with it's terminal.

@jynx ok thats good to know. I'll have to educate myself about the scripting side of ed.

@jynx I dont think there is much reason to use ed unless you are using a teletype or on a real limited connection like 300baud or packet radio.

@W10x12_UNO Ask him if Berkeley owns Free/Net/OpenBSD. πŸ€”

@publius @capngloval yesterday I was in alpine but then it crashed out. I tried to log in but sshd couldn't spawn a shell. Today I can log in but no alpine. I hope it is nothing serious πŸ™

@apiziali It has done that for me when I have my TERM set to something wacky. Try doing a
export TERM="vt100" and see if it loads?
