🍎 Apple IIc ROM 4X Upgrade Kit - Brand New ROM!

Add to Cart
Upgrade your Apple IIc to ROM 4x

This kit is used to upgrade an Apple IIc (ROM versions 255, 0, 3 or 4) to version 4X. The "kit" consists of the ROM 4X chip and an 8-page photo-illustrated step-by-step guide on CD on doing the upgrade yourself. Our ROMs are brand new chips, not recycled.

Please note that soldering skills are required if you are upgrading from a ROM 255 or ROM 0; there is a small bit of soldering to be done on the motherboard. If you are upgrading from a ROM 3 or ROM 4, it is a simply chip swap. Providing the manual on CD allows you to magnify the 8 high-def photos as much as you desire to see details! Please also note that there are a few motherboards which will not accept the upgraded chip. We do not know of any way to determine this in advance; the only way to know is to perform the upgrade and if the system does not work, revert back to your original chip.

Critical Note: ROM 4X is a non-official-Apple version created by mgcaret & offers several improvements/changes over the earlier ROM4 version. From mgcaret's github page:

ROM 4X adds the following features to the Apple //c firmware:

♦ Identifies and reinstates a bootable (it must have something that looks like a boot block!) RAM disk from battery-backed expansion memory.
♦ Provides a menu of various tools upon pressing Ctrl+Closed-Apple+Reset (or holding Closed-Apple when powering up), that let you:

♦ Enter the monitor unconditionally.
♦ Reboot the machine (enter standard boot sequence).
♦ Zero the RAM card, in case it is corrupted.
♦ Execute the machine and RAM card diagnostics.
♦ Tell the machine to boot the SmartPort, the internal floppy drive, or an external floppy drive.
♦ The system drops to BASIC if no bootable device is found (this is the default behavior in the IIc Plus).
♦ Configure default boot device by saving a file on the RAM Disk.
♦ XModem-CRC support.

Please note: This is a non-official Apple version of the chip. If you would prefer to have the official Apple Corp. version ROM 4 chip, please see our other listings.

We personally QA test each chip to ensure it works BEFORE packaging.

This package includes:
♦ Brand New Apple IIc ROM 4X upgrade chip
♦ 8-page photo-illustrated directions on CD (not shown in photos)
♦ Protective lidded box to protect the old ROM chip after it is removed.

Our kits are shipped in boxes, not padded envelopes, to ensure that the chip arrives safe and sound without bent or broken pins.

Payment Policy

Payment via PayPal ONLY. Valid email address & phone number are required. Please make sure that both are present on your PayPal payment so shipping is not delayed.

Please Note: Commencing January 2020 - PayPal has ceased refunding PayPal fees for all cancelled/refunded transactions. As such, all non-refundable PayPal fees will be deducted from refunds.

For example: If you make a PayPal payment to us with an incorrect ship-to address, you will need to submit a new payment to us with the correct ship-to address. Your original payment to us will be returned to you less the non-refundable PayPal fees.

NON-USA CUSTOMERS: Please contact us BEFORE purchasing (1) to see if we ship to your country and (2) what the additional S&H fees are for international shipping. If you fail to do so, we will send you a PayPal Invoice for the additional S&H. If you elect not to proceed with the sale, we will refund your original payment less the non-refundable PayPal fees.

Shipping Policy

You MUST send us your daytime phone number & email address in a note attached to your purchase, as this information is required for our Sales & Inventory System. If this is unacceptable to you, please do not purchase.

Return/Exchange Policy

All items are tested to work properly prior to listing, unless otherwise specifically stated in the item's ad. Because vintage electronic components may go south without advance warning, The Apple2OnlineStore does not offer any extended warranties. Unless otherwise stated, hardware components and systems are guaranteed to work upon receipt. Buyers have 7 days from delivery to determine if their purchase is working properly or needs to be returned. If a return is necessary, contact us to receive an Return Merchandize Authorization.

Returned Items MUST be in the exact same condition as were shipped. Any alterations will affect your refund. The Apple2OnlineStore is the sole arbitrator of alterations and refund deductions for such.

Other Policies

Our store host - eBluejay - does not charge any fees whatsoever. Compare to eBay, which charges 12.5% fees on both the cost of the item AND shipping - which, through the wonders of compounding interest, result in a 20%-25% increase in price to the customer. We do occasionally dual list items so when you see one of our items on eBay, check her first as the price is usually less (and on larger items, significantly so!).

Please note that as of January 2020, PayPal's now non-refundable fees will be deducted from refunds given by The Apple2OnlineStore (see Payment Policy above).

Our store policies are for our safety as well as your's! We like to work with our customers and be as flexible as is reasonably possible. If you have an issue with your order, please contact us as soon as possible in order to get a satisfactory resolution. Please realize that we, too, are human and make mistakes, as well as have family demands which occasionally make demands on our time.

Vintage electronics are subject to failure. Unless otherwise specifically stated in a listing, our items have been thoroughly inspected and tested and their condition is clearly stated in the listing. Please realize that vintage electronics are subjected to a variety of environmental conditions during transit: extreme temperatures, magnetic fields, rough handling, etc. If you receive a non-functional and/or physically damaged item, please contact us immediately as most items are insured against loss or damage. Please keep ALL packaging materials as the shipper requires you to present the damaged contents along with ALL packing materials for inspection. Your cooperation in submitting the contents to the shipper (USPS, FedEx, UPS) is required for successful insurance claims.
