It used an 8-pin TI switching chip to generate the programming voltages. Being from the “so, use a bigger hammer” school of thought, I un- soldered the switcher and instead ran some cables from a nice Lambda 50A regulated bench supply to the programmer. The ST Microelectronics part referenced above has a 64 byte page buffer, which means you can write up to 64 bytes to it – quickly – then pause and all 64 will program at once. Reason Report to Moderators I think this message isn’t appropriate for our Group.
When I set up my shop a few years ago when I started grad school, I got a programmer from Conitec. D to be more accurate: Their site has forums that may point you in the right direction.
Sometimes 2 extra supplies. This cannot be undone. To go even more off-topic At 10mS per byte, it would get quite tiresome.
No contracts, No fees, No Kidding! Do they require an exact datasneet pulse to be applied to the “not WE” pin, in order to write to it? What do I need to do, in order to write data to the or 28C16?

Been there and successfully done both. Thanks anyway for your valuable time. Are you sure you wish to delete this message from the message archives of neonixie-l groups. I got away with just using a 74C keyboard encoder, and feeding an inverted version of the “valid data” output from that, directly to “not WE” on the Dallas part.
There was a most satisfying “BLAM! Datasgeet when I just got started in the electronics business, I was working as tech and general slave. Writing was a bit different.

The intent for these devices was to hold configuration info, and other field alterable data. The new topic will begin with this message. Some as low a 10, Reminds me of the Old Apple ][ Disk ][ Drives.
What am I missing here? The Group moderators are responsible for maintaining their community and can address these issues. I think it’s an open-source homebrew programmer — you can build it daasheet or buy it already built.
EEPROM, slightly O.T.
Once I fixed that it has been great, and the blame goes to the Korean manufacture of my particular unit rather than the design itself. It reads just fine, but it won’t take any new data. First hit on google: That’s why several types of memory datazheet similar pinouts, though hardwire jumpers also had to be set, due to the differences.
It was an ‘ad-hoc’ job, using pre-existing assemblies. Again, read the data sheet carefully and make sure it’s for the exact same device and manufacturer. Back in datasbeet late ‘s I had an S ratasheet programmer that did ‘s and ‘s. A RAM device, obviously, can be written to, about the same speed as it can be read. Mine did arrive with a construction error though, a resistor was the wrong value and caused the programming voltage to be too low and writing would fail most of the time after the first few uses.
Chuck Datashewt Chuck, The is an electrically-erasable version of the The 8-bit CPUs back then all had bit address buses and, therefore, a max memory space of 64K 65, bytes.
