Re: My TS1000 is lifeless

When I went to the Commodore 64 it became a monthly routine to pop the case and re-seat all the chips as they would gradually "walk" themselves out of their sockets. Although the "old" ULA seemed to be firmly in its socket, I may just have to take a shot at giving it another try. As always, thanks f...

Re: My TS1000 is lifeless

By "lifeless" I meant that "No Signal" was displayed on the monitor. Sorry for the lack of clarity. The ULA and and Z80 are socketed. I gave each a good push into the socket and they seemed fine. After my posting I realized I had two spare ULAs to try, one a reclaim and the other from Andy. I pulled...

My TS1000 is lifeless

It has been a few months since I last powered up my TS, but today it is showing no signs of life. Was functioning just fine the last time used. Voltage from the power supply is good, and got 4.7 and 9 volts when checked at the Traco. and connection is good to the ZX8-CCB. It had previously been fitt...

Zxpand+ boards available once again

Just a heads-up for everyone that Sirmorris has just re-listed a quantity of 50 Zxpand+ boards available on the SMR site.

https://www.sellmyretro.com/offer/details/40565

It is a pre-order as was the last batch, which were all claimed within a couple of hours.

Cheers,

Mike

I have decided to part with the untouched ZX80 replica kit I purchased last year from Oricfan on Ebay. It is in as-received condition.

Price is $125 USD plus shipping. Does not include case or power supply.

Re: ZX Printer Belt

Yes, the printer I recently purchased came from there. Some evil unseen force coerced me into opening it up to have a look-see at the belt Ian is using. This, of course, voided the warranty, but all in the name of science, right? Dimensionally they are for all practical purposes identical. I don't k...

Re: ZX Printer Belt

Hey Vopni. Thanks for the complements. Yes, a lot of time and effort have gone into this project and none of it could have been possible without the help and information from a lot of great folks on the forum. Standing on the shoulders of giants, as it were. I don't have them for sale yet due to a c...

Re: 3K Rampack issues

Yes, the 74LS138 was fitted. I'l try your suggestion using only one RAM chip at a time in those locations.

Then I'll probably just sob quietly to myself over in the corner.

Re: 3K Rampack issues

Hey Mark. Yeah I probably mis-named the 74LS138 1 of 8 Decoder / Demultiplexer IC as a "timer" chip out of my abundant ignorance. Thanks for the info on addressing schemes on the machines. That's good stuff I am trying to digest. The TS edge connector has little wear and is clean. Plugging my ZXpand...
