I really like both seller and product.

For CGA2RGBv2 - Digital to Analog RGB for MDA/CGA/EGA

The product works as I expected without any complications. I highly recommends both product and seller if you have any retro computer with CGA.

Good little test rig if you are messing with RS232.

For T232 - Mini RS-232 Monitor and Breakout

I mess alot with retro computer equipment, a lot of which use RS232 are the primary means of communications. So this little rig is perfect when I am trying to get systems talking.

This would have save me a lot of time when restoring a SUN SPARCStation a year ago as getting the custom console cable working was a chore.

Well worth the money and is now an important part of my Serial cabling kit.

Perfect exact fit

For Replacement power switch DPDT Commodore 64/128

This is a great product and exact replacement for original power switch. I have installed one in my "SixtyClone", C64 replica pcb. I'm building an all new C64 with modern replacements for obsolete MOS chips. This switch could not be sourced through the usual vendors, so very happy to find it available on Tindie.

Nice addition to SE/30

For MACSIMM - MAC SE/30 IIsi IIfx flash ROM SIMM

I'm using this on my SE/30 to skip the startup RAM test and use the full amount of RAM without MODE32. I haven't had a chance to flash the ROM to include a custom bootdisk, but I love how that's an option!

Does exactly what it should

For T232 - Mini RS-232 Monitor and Breakout

Very nice card which does exactly what it should.

I ordered an unassembled card and could not find build instructions here in Tindie or on their website. Most of the assembly was obvious some wasn't. I figured out which end got the male and which end got the female DB-9 from the pictures. It matters since the silkscreen would wrong for the signals if they were reversed.

The resistor pack orientation wasn't obvious and the "normal" convention of pin 1 being near the silkscreen wasn't right. Fortunately, I figured it out before soldering it in place. Pin 1 is the common and goes to the ground pad which was easy to spot on the bottom traces.

What I couldn't figure out was the correct LED part orientation. The LED is one of those 8 bidirectional LEDs in a DIP package. I assumed it matters since the LED color is a function of orientation. I picked a direction which was likely wrong since good on the Tx/Rx shows as red. I think the "right" orientation is probably to have the side of the LED with the marking go towards the R-pack. I'm not sure if the design intent was correct or not since Tx/Rx normal states are reversed from handshake normal states. The way I built it shows Rx/Tx as red and RTS/CTS as green. I'd prefer if a "good" state was green on all the lines but that would mean flipping the handshake or Tx/Rx pins into the LEDs and putting the part in the right way.

If the designer just filled in these details for builders this would be a perfect project. Or just order it assembled.

Lots of ram, more space in the case.

For RAMGS/4 - 4MB expansion for Apple IIgs

Replaced my old 1gig card with this, 4times the memory 1/3 of the physical space used. Good communication from seller, and fast shipment.

no issues!

For GS2HD - Apple IIgs RGB to HDTV Component Adapter

No issues, My IIgs is happy now. solid video output. not sure how the soldered on rgb port will hold up, but it seems sturdy for now.

Just perfect.

For RAMGS/8 - 8MB expansion for Apple IIgs

Really, just a perfect product. Well designed (just 2 ICs and a few passives), up to the task, compatible, and a reasonable price (could be a bit cheaper, but let's face it, it is a niche market). Keep up the good work.

Kay | Sept. 12, 2021

It's great for 68K Macs

For MACSIMM - MAC SE/30 IIsi IIfx flash ROM SIMM

I have three of them, but the ROM is removable so it can be used by rom programmers, which is convenient.
Next, I will try to edit the ROM.

Gregory | Sept. 11, 2021

SE30 restoration project Phase 1

For MACSIMM - MAC SE/30 IIsi IIfx flash ROM SIMM

Just get the hardware running, and tricked out with a nice 32bit clean ROM upgrade!

Next is complete rebuilds of the power supply and analog electronics boards so this baby outlives me!

A2SCSI - great addition to an Apple ii

For A2SCSI - SCSI Card for Apple II IIgs IIe II+

It’s great! I’m using mine to boot my enhanced Apple iie from a Zip drive, and you can also use Sony SCSI CD drives with an Apple ii.

Works great, no complaints with the card.

Only complaint is that Asendia is a terrible shipping company - but that isn’t the sellers fault!

Works as advertised.

For RAMGS/8 - 8MB expansion for Apple IIgs

Works as advertised. Some direction as to installation would have been helpful, but I was able to find some good photos online. The word "front" is printed on the card and the only clue you get. Standard protocol regarding static discharge and making sure your machine is turned off, etc., apply of course.
Overall, this is a good product: Small, uses less power, creates less heat, does not have dozens of chips to reset regularly, cannot 'wiggle' and touch your SCSI card in slot-7. I am very happy with it. Competitively priced.

Beautiful results on Commodore 128

For CGA2RGBv2 - Digital to Analog RGB for MDA/CGA/EGA

I'm using the CGA2RGBv2 with a Commodore 128 for its 80-column RGBI port, plugged into an OSSC (Open Source Scan Converter). The picture is emulator-clear - razor sharp and flicker free once OSSC is properly configured. I don't have any 15kHz capable displays, which is why I needed to use CGA2RGBv2 in conjunction with an upscaler. HIGHLY recommend and good documentation on the seller's website https://gglabs.us/

I would have liked an optional pre-made USB-A power cable to be available for an extra charge, but wasn't hard to make once I borrowed the appropriate tools.

Perfect

For RAMGS/8 - 8MB expansion for Apple IIgs

From ordering to shipping, everything perfect. Anytime again. xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxThanks

Great product

For RAMGS/4 - 4MB expansion for Apple IIgs

Works exactly as advertised. Great way to keep old Apple IIGS alive a while longer now that original expansion boards are getting hard to find!

Timothy | Oct. 10, 2018

Tiny, beautiful, and works great!

For RAMGS/4 - 4MB expansion for Apple IIgs

An easy way to fill your Apple IIgs with lots of memory.

I had an old RamPro card in my ROM3 GS with only 2 MB of RAM installed on it. Recently I decided to upgrade it to 4 MB but I found that the memory chips for it are no longer easily available. Rather than try to scrounge together expensive old chips from eBay or similar, I decided to go the easy route and buy a brand new RAMGS/4. No hassle, easy availability, and no messing around with installing chips or flipping DIP switches.

Now my GS has more memory than I'm likely to need and I know my memory card is new and reliable. And I bet it generates less heat than the old one (always a concern in a GS packed full of cards).

Probably the most useful device I've seen.

For T232 - Mini RS-232 Monitor and Breakout

It is exactly what is useful to examine the operation of RS-232 interconnections. Excellent addition to my tool box . Recommended highly for troubleshooting RS-232 problems since each line is both broken out and switchable in or out. Nice device.

Łukasz | June 5, 2018

Highly recommended for any IIGS owner

For RAMGS/4 - 4MB expansion for Apple IIgs

Zero problem with the shipment and delivery, the RAM expansion works in my IIGS ROM1 like a charm. System 6.0.1 and all of the games are running with no issues. Highly recommended!

Nice board, but no docs

For RAMGS/8 - 8MB expansion for Apple IIgs

The RAMS/8 works really well, and replaces the huge Apple RAM expansion board nicely. Everything I've thrown at the board under GS/OS indicates that the board works perfectly.

A little bit more documentation might be nice, though. There's none in the package, and none that I could find on the vendor's website. Only a small mark on the board indicates which way round it should be installed. It might be nice to have some links to RAM tests or other diagnostics too.
